Description
本発明は、金属加工工程に使用される水溶性金属加工油剤組成物の原液を貯水タンクへ投入し希釈液を調整する際、並びに、水溶性金属加工油剤使用液へ投入し水溶性金属加工油剤組成物の補給や成分濃度の調整を行う際の簡便かつ安全な薬剤投入に使用する単位用量物及びその希釈液の製造方法に関する。 The present invention relates to a unit dose used for simple and safe drug addition when preparing a diluted solution by adding an undiluted solution of a water-soluble metalworking oil composition used in a metalworking process to a water storage tank, and when adding the diluted solution to a working solution of a water-soluble metalworking oil composition to replenish the water-soluble metalworking oil composition or adjust the concentration of the components, and a method for producing the diluted solution.
金属加工工程においては、一般的に、水溶性の金属加工油剤が使われている。金属加工油剤は、原液のまま使用されることはなく、タンクや槽に原液を所定量投入し、水で希釈した希釈液を調整して使用される。そして、使用液は、経時による成分バランスの変化や成分の劣化等による種々のトラブルの未然防止のため、定期的な原液や添加剤等補給により使用液の濃度管理を実施している。 Water-soluble metalworking oils are generally used in metalworking processes. Metalworking oils are never used as is; a specified amount of the stock solution is poured into a tank or vat and diluted with water to prepare a diluted solution. The concentration of the used solution is controlled by regular replenishment of the stock solution and additives to prevent various problems caused by changes in the balance of components over time and deterioration of the components.
この希釈作業や補給作業時には、作業者が油剤原液や添加剤等をその都度秤量する手間がかかるだけでなく、油剤原液や添加剤等と直接接触することによる手荒れの危険性や触れないまでも油剤原液の発する臭気が問題となったりしている。 When diluting or replenishing, not only does it take time for workers to weigh out the concentrate oil and additives each time, but there is also the risk of rough hands from direct contact with the concentrate oil and additives, and even if workers do not touch the concentrate oil, the odor emitted by the concentrate oil can be a problem.
これらの問題を解決する対策として、工業薬品メーカーでは、手荒れを起こしにくい皮膚刺激性の少ない配合を工夫したり、臭気のマイルドな原料を選定する等の対策を行っている。 To address these issues, industrial chemical manufacturers are taking measures such as creating formulations that are less likely to cause skin irritation and dry hands, and selecting raw materials with a mild odor.
また、金属加工油剤を使用する金属加工工場では、例えば、自動希釈装置を導入する等の対策を行っている。自動希釈装置を用いれば、作業者がその都度油剤原液を秤量する手間をなくす事ができる点や直接接触による危険性を回避する事ができる点等のメリットが図れる半面、自動希釈装置は導入に費用がかかる点で問題であり、導入しても、構造的に原液をポンプアップする構造を有しているため、原液が高粘度の場合に適用できない等の制限もある。 Metalworking factories that use metalworking oils have taken measures such as installing automatic dilution devices. While the use of automatic dilution devices has the advantage of eliminating the need for workers to measure the stock oil each time and of avoiding the risk of direct contact, the problem is that automatic dilution devices are expensive to install, and even if installed, they have limitations such as being structurally designed to pump up the stock solution, meaning they cannot be used when the stock solution is highly viscous.
一方、家庭用洗剤の分野では、このような秤量の手間を省き、化学物質との接触を回避、更に、包装材の廃棄処理の省略化等の観点から、ポリビニルアルコール(PVA)等の水溶性樹脂フィルムからなる包装容器に洗剤を入れた単位用量物(ユニット包装)が提案され用いられている(例えば、特許文献1、2参照)。 Meanwhile, in the field of household detergents, from the viewpoints of eliminating the need for weighing, avoiding contact with chemicals, and further shortening the disposal process of packaging materials, unit dose products (unit packaging) in which detergent is placed in a packaging container made of a water-soluble resin film such as polyvinyl alcohol (PVA) have been proposed and are in use (see, for example, Patent Documents 1 and 2).
しかるに、この単位用量物を使用する方法は、工業薬品の分野では、実用化に至っていない。その要因としては、(1)希釈作業では、薬剤投入対象は洗濯の場合と同様に真水であるが、補給作業では、薬剤投入対象は真水ではなく、金属加工油剤の各化学成分を含有した水である;(2)家庭用洗濯機の場合に比べ、工業用のタンク容量は圧倒的に大きく、その割にタンクの攪拌力は洗濯機のように強力ではない;(3)家庭用洗剤の場合、各家庭で使用されている洗濯機の洗濯容量に大きな差異はなく、洗剤メーカーは一定量の単位用量物を供給すればよいが、工業薬品の分野では、各金属加工工場に設置されているタンクや槽の容量はまちまちである;等が挙げられる。 However, this method of using unit doses has not yet been put to practical use in the field of industrial chemicals. The reasons for this include: (1) in dilution, the agent is added to fresh water, just like in laundry, but in refilling, the agent is not added to fresh water, but to water containing the various chemical components of metalworking oils; (2) compared to household washing machines, the tank capacity of industrial machines is overwhelmingly larger, but the mixing power of the tank is not as strong as that of washing machines; (3) in the case of household detergents, there is not much difference in the washing capacity of washing machines used in each household, so detergent manufacturers only need to supply a fixed amount of unit doses, but in the field of industrial chemicals, the capacity of tanks and tubs installed in each metalworking factory varies; etc.
このような工業薬品分野、特に、金属加工において実用化可能な水溶性単位用量金属加工油剤組成物を提供することを目的とする。 The objective of this study is to provide a water-soluble unit-dose metalworking oil composition that can be put to practical use in the industrial chemical field, particularly in metalworking.

本発明の水溶性単位用量金属加工油剤組成物を用いることにより、工業薬品分野、特に、金属加工において、油剤の投入対象が真水ではなく油剤の化学成分を含有した水に対しても使用でき、弱い攪拌でも易溶性を示し、異なるタンク容量にも対応できるようになった。 By using the water-soluble unit dose metalworking oil composition of the present invention, it can be used in the industrial chemical field, particularly in metalworking, where the oil is not added to fresh water but to water containing the chemical components of the oil, and it is easily soluble even with weak stirring and can be used in tanks of different capacities.
工業薬品分野、特に、金属加工において、家庭用洗剤分野と異なる要因の一つは、油剤の投入対象が真水だけでなく油剤の化学成分を含有した水に対しても易溶性を必要とし、さらに洗濯機ほどの撹拌が行われないため水溶性フィルムの溶解に時間がかかること、工業製品は用量が大きく、十分な強度を持たせようとして水溶性フィルムの膜厚を厚くするとさらに溶解に時間がかかることである。 One of the factors that makes the industrial chemical field, especially metal processing, different from the household detergent field is that the oil needs to be easily soluble not only in fresh water but also in water that contains the chemical components of the oil, and since there is no agitation to the same extent as in a washing machine, it takes time for the water-soluble film to dissolve, and because the amount of water used in industrial products is large, making the water-soluble film thicker to ensure sufficient strength takes even longer to dissolve.
本発明の水溶性単位用量金属加工油剤組成物は、真水及び油剤の化学成分を含有する水に速やかに溶解し、かつ輸送時の衝撃に耐え、長期保存時においても十分な強度を有するものである。なお、本明細書では水溶性包装容器に水溶性金属加工油剤組成物を封入したもの、ならびに水溶性包装容器に水溶性金属加工油剤組成物を構成するために使用する成分(本明細書では水溶性金属加工油剤構成成分と称する。)を封入したものを総称して、水溶性単位用量金属加工油剤組成物と称する。 The water-soluble unit dose metalworking oil composition of the present invention dissolves quickly in fresh water and in water containing the chemical components of the oil, is resistant to shocks during transportation, and has sufficient strength even when stored for a long period of time. In this specification, the term water-soluble unit dose metalworking oil composition refers collectively to a water-soluble packaging container in which the water-soluble metalworking oil composition is enclosed, and a water-soluble packaging container in which the components used to constitute the water-soluble metalworking oil composition (referred to as water-soluble metalworking oil components in this specification) are enclosed.
水溶性金属加工油剤組成物は、主剤である基油、油性剤、界面活性剤に対し、添加剤として潤滑向上剤、防錆剤、消泡剤、極圧剤、カップリング剤、防食剤、防腐剤、抗菌剤、キレート剤、油分離剤、着色剤、香料等から選択される成分を含むものであり、水で希釈して使用する。基油としては鉱物油(スピンドル油、軽油、灯油、マシン油等)、合成油(ポリオレフィン、ジエステル類、ヒンダードエステル類等)が挙げられ、油性剤としては菜種油、大豆油、ひまし油、ヤシ油等の植物油、及びラード等の動物油が挙げられる。界面活性剤としては、アニオン界面活性剤、カチオン界面活性剤、ノニオン界面活性剤、両性界面活性剤が挙げられ、アニオン界面活性剤、カチオン界面活性剤、ノニオン界面活性剤が好ましい。防錆剤としては、有機カルボン酸、有機アミン等が挙げられ、これらを併用してもよい。極圧剤としては、硫黄系、リン系、有機金属化合物等が挙げられる。防腐剤としてはフェノール系、ホルムアルデヒド供与体等が挙げられる。カップリング剤としてはアルコール類が挙げられる。 The water-soluble metalworking oil composition contains additives selected from lubrication improvers, rust inhibitors, antifoaming agents, extreme pressure agents, coupling agents, anticorrosive agents, preservatives, antibacterial agents, chelating agents, oil separating agents, colorants, fragrances, etc., in addition to the base oil, oil agent, and surfactant, and is used by diluting with water. Examples of base oils include mineral oils (spindle oil, diesel, kerosene, machine oil, etc.), synthetic oils (polyolefins, diesters, hindered esters, etc.), and examples of oil agents include vegetable oils such as rapeseed oil, soybean oil, castor oil, and coconut oil, and animal oils such as lard. Examples of surfactants include anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants, with anionic surfactants, cationic surfactants, and nonionic surfactants being preferred. Examples of rust inhibitors include organic carboxylic acids and organic amines, and these may be used in combination. Examples of extreme pressure agents include sulfur-based, phosphorus-based, and organometallic compounds. Examples of preservatives include phenols and formaldehyde donors. Coupling agents include alcohols.
水溶性金属加工油剤組成物の代表的タイプとしては、水に乳化するエマルションタイプ(JIS分類のA1種)、水に溶解するソルブルタイプ(JIS分類のA2種)及びソリューションタイプ(JIS分類のA3種)が挙げられる。水溶性金属加工油剤組成物の希釈倍率は用途によって異なるが、通常は5~100倍程度、好ましくは10~50倍程度である。 Representative types of water-soluble metalworking oil compositions include emulsion types that emulsify in water (JIS classification type A1), soluble types that dissolve in water (JIS classification type A2), and solution types (JIS classification type A3). The dilution ratio of water-soluble metalworking oil compositions varies depending on the application, but is usually about 5 to 100 times, and preferably about 10 to 50 times.
エマルションタイプは、水で希釈して乳白色のエマルションを形成するものであり、基油及び/又は油性剤と乳化剤である界面活性剤を含むものが一般的である。ソルブルタイプは、エマルションタイプにおいて界面活性剤の配合量を増やしたものが挙げられ、合成ポリマーを基油とするのが一般的であり、半透明又は透明な溶液となる。ソリューションタイプは、ポリアルキレングリコール等の水溶性潤滑剤を主成分とするものが挙げられる。
これらのうち、油剤を含む溶液に速やかに溶解する観点から、水溶性包装容器に封入される水溶性金属加工油剤組成物はエマルションタイプの油剤組成物が好ましい。
The emulsion type is diluted with water to form a milky emulsion, and generally contains a base oil and/or oil agent and a surfactant as an emulsifier. The soluble type is an emulsion type with an increased amount of surfactant, generally uses a synthetic polymer as the base oil, and forms a translucent or transparent solution. The solution type is a type that contains a water-soluble lubricant such as polyalkylene glycol as the main component.
Of these, the water-soluble metalworking oil composition to be sealed in a water-soluble packaging container is preferably an emulsion-type oil composition, from the viewpoint of rapid dissolution in a solution containing an oil.
水溶性包装容器に封入される水溶性金属加工油剤組成物の水の含有率は10質量%未満であることが、水溶性包装容器の強度を維持するために好ましい。また、水溶性包装容器に封入される水溶性金属加工油剤組成物の原液のpHは、好ましくは7.5~12であり、より好ましくは7.5~10である。水溶性金属加工油剤組成物がアルカリ性から弱アルカリ性である場合、水溶性包装容器を構成する水溶性フィルム材料はアルカリ耐性を有することが好ましい。 In order to maintain the strength of the water-soluble packaging container, it is preferable that the water content of the water-soluble metalworking oil composition enclosed in the water-soluble packaging container is less than 10% by mass. In addition, the pH of the undiluted water-soluble metalworking oil composition enclosed in the water-soluble packaging container is preferably 7.5 to 12, more preferably 7.5 to 10. When the water-soluble metalworking oil composition is alkaline to weakly alkaline, it is preferable that the water-soluble film material constituting the water-soluble packaging container has alkali resistance.
水溶性包装容器に使用する水溶性フィルム材料は、水溶性であれば特に限定されないが、例えばポリビニルアルコール、ヒドロキシエチルセルロース、ポリビニルピロリドン、デンプン、グリセリン、ゼラチン等から選択される1又は2以上の樹脂を含む水溶性フィルム材料が例示される。中でも、ポリビニルアルコールを含む水溶性フィルム材料は、ポリビニルアルコールの重合度、ケン化度、デンプン等の添加剤の配合等の諸条件を変化させることによって、必要な機械的強度や取り扱い中の耐湿性を制御することができるため、好ましく用いられる。 The water-soluble film material used for the water-soluble packaging container is not particularly limited as long as it is water-soluble, but examples include water-soluble film materials containing one or more resins selected from polyvinyl alcohol, hydroxyethyl cellulose, polyvinylpyrrolidone, starch, glycerin, gelatin, etc. Among them, water-soluble film materials containing polyvinyl alcohol are preferably used because the required mechanical strength and moisture resistance during handling can be controlled by changing various conditions such as the polymerization degree of polyvinyl alcohol, the degree of saponification, and the blending of additives such as starch.
ポリビニルアルコール(PVA)の市販品では、例えば、MonoSol社のM8630、M8900が使用できる。 Commercially available polyvinyl alcohol (PVA) products that can be used include, for example, MonoSol's M8630 and M8900.
水溶性フィルム材料の好ましい膜厚は、約40~70μm、さらに好ましくは約45~64μmである。フィルムの膜厚が約40マイクロメートル~約70マイクロメートルであれば、十分な膜強度を有し、かつ、実用的な膜溶解性を有する。市販品では、例えば、MonoSol社のM8630の2.0mil(51μm)が最適である。 The preferred thickness of the water-soluble film material is about 40 to 70 μm, and more preferably about 45 to 64 μm. If the film thickness is about 40 micrometers to about 70 micrometers, the film has sufficient film strength and practical film solubility. For example, MonoSol's M8630 2.0 mil (51 μm) is optimal as a commercially available product.
水溶性包装容器には水溶性金属加工油剤組成物を構成するために使用する成分(水溶性金属加工油剤構成成分)、つまり主剤及び/又は添加剤を封入することができる。主剤としては基油、油性剤、界面活性剤等が挙げられ、添加剤としては潤滑向上剤、防錆剤、消泡剤、極圧剤、カップリング剤、防食剤、防腐剤、抗菌剤、キレート剤、油分離剤、着色剤、香料等が挙げられる。水溶性包装容器に封入する水溶性金属加工油剤構成成分は単体成分でも良いし、混合成分でも良い。混合成分は主剤同士の混合、添加剤同士の混合、主剤と添加剤との混合が挙げられる。また、水溶性金属加工油剤構成成分は、水で希釈することもできる。 The water-soluble packaging container can contain the components (water-soluble metalworking oil components) used to form the water-soluble metalworking oil composition, i.e., the main component and/or additives. Examples of the main component include base oil, oiliness agent, surfactant, etc., and examples of the additives include lubrication improvers, rust inhibitors, antifoaming agents, extreme pressure agents, coupling agents, corrosion inhibitors, preservatives, antibacterial agents, chelating agents, oil separating agents, colorants, fragrances, etc. The water-soluble metalworking oil components to be contained in the water-soluble packaging container can be a single component or a mixed component. Examples of the mixed components include a mixture of main components, a mixture of additives, and a mixture of a main component and an additive. The water-soluble metalworking oil components can also be diluted with water.
水溶性包装容器に封入する水溶性金属加工油剤構成成分の水の含有率は10質量%未満であることが、水溶性包装容器の強度を維持するために好ましい。また、水溶性包装容器に封入される水溶性金属加工油剤構成成分のpHは、好ましくは7.5~12であり、より好ましくは7.5~10である。水溶性金属加工油剤構成成分がアルカリ性から弱アルカリ性である場合、水溶性包装容器を構成する水溶性フィルム材料はアルカリ耐性を有することが好ましい。このため水溶性金属加工油剤構成成分を封入する水溶性包装容器に使用する水溶性フィルム材料はポリビニルアルコール(PVA)を含んでいることが好ましく、水溶性フィルム材料の膜厚は好ましくは約40~70μmであり、さらに好ましくは約45~64μmである。 In order to maintain the strength of the water-soluble packaging container, it is preferable that the water content of the water-soluble metalworking oil components enclosed in the water-soluble packaging container is less than 10% by mass. The pH of the water-soluble metalworking oil components enclosed in the water-soluble packaging container is preferably 7.5 to 12, more preferably 7.5 to 10. When the water-soluble metalworking oil components are alkaline to weakly alkaline, it is preferable that the water-soluble film material constituting the water-soluble packaging container has alkali resistance. For this reason, the water-soluble film material used in the water-soluble packaging container that encloses the water-soluble metalworking oil components preferably contains polyvinyl alcohol (PVA), and the film thickness of the water-soluble film material is preferably about 40 to 70 μm, more preferably about 45 to 64 μm.
水溶性金属加工油剤組成物を貯水タンクへ投入し希釈液を調整する際、並びに、水溶性金属加工油剤使用液へ投入し水溶性金属加工油剤組成物の補給を行う際に、上述の水溶性フィルム材料で形成された水溶性包装容器に水溶性金属加工油剤組成物、好ましくはエマルションタイプ油剤組成物を封入した単位用量物(以下、本発明品と記す)を使用すれば、弱い攪拌でも易溶性を示す。 When the water-soluble metalworking oil composition is poured into a water storage tank to prepare a dilution solution, and when the water-soluble metalworking oil composition is poured into a water-soluble metalworking oil working solution to replenish the water-soluble metalworking oil composition, if a unit dose product (hereinafter referred to as the present invention) in which the water-soluble metalworking oil composition, preferably an emulsion-type oil composition, is enclosed in a water-soluble packaging container formed from the above-mentioned water-soluble film material is used, the water-soluble metalworking oil composition will be easily soluble even with weak stirring.

(1)前記水溶性包装容器が切り離し可能な複数の区画を有し、前記区画が、水溶性金属加工油剤組成物を封入する少なくとも1種の区画と水溶性金属加工油剤構成成分を封入する少なくとも1種の区画を有する形態。

(6) The water-soluble packaging container has a multi-layer structure, and each layer contains a water-soluble metalworking oil component.
水溶性金属加工油剤の各区画又は各層における封入量は、特に限定されないが、好ましくは100~1000g(あるいは100~1000ml)の範囲とすることができ、例えば100g(あるいは100ml)及び/又は、500g(あるいは500ml)及び/又は、1000g(あるいは1000ml)とすることができる。貯水タンク等への油剤の投入量が数十キログラムないし数百キログラムに達する場合は、ドラム仕様あるいは1斗缶仕様の油剤を使用し、それで不足する半端量を本発明品で補えば良い。従って、必要になるのは、数キログラムないし数百グラムに対応した封入量の単位用量物である。これらの封入量の単位用量物を用意すれば、通常の異なるタンク容量の油剤希釈液調整作業や補給作業に支障はない。また、水溶性金属加工油剤構成成分の各区画又は各層における封入量も上記同様、特に限定されないが、好ましくは100~1000g(あるいは100~1000ml)の範囲とすることができ、例えば100g(あるいは100ml)及び/又は、500g(あるいは500ml)及び/又は、1000g(あるいは1000ml)とすることができる。 The amount of water-soluble metalworking oil in each compartment or layer is not particularly limited, but can be preferably in the range of 100 to 1000 g (or 100 to 1000 ml), for example 100 g (or 100 ml) and/or 500 g (or 500 ml) and/or 1000 g (or 1000 ml). When the amount of oil to be put into a water storage tank reaches several tens to several hundreds of kilograms, a drum or 18 liter can of oil can be used, and the remaining amount can be made up with the product of the present invention. Therefore, what is needed is a unit dose of the amount of oil corresponding to several kilograms to several hundreds of grams. If unit doses of these amounts are prepared, there is no problem with the usual oil dilution adjustment and refilling work for tanks with different capacities. Similarly, the amount of water-soluble metalworking oil components enclosed in each compartment or layer is not particularly limited, but is preferably in the range of 100 to 1000 g (or 100 to 1000 ml), for example 100 g (or 100 ml) and/or 500 g (or 500 ml) and/or 1000 g (or 1000 ml).
水溶性単位用量金属加工油剤組成物の取りうる形態として、例えば図1に示すように、本発明の水溶性単位用量金属加工油剤組成物1に使用される水溶性包装容器2は、ミシン目3を備えることができ、複数の封入された部分をもち、ミシン目3で個々に切り出すことが可能な構成としてもよい。図1の水溶性単位用量金属加工油剤組成物1は、水溶性金属加工油剤組成物の主となる量(大容量)を封入する区画4と、微調整用の小容量の同一成分の水溶性金属加工油剤組成物を封入した区画5を備えたものである。水溶性金属加工油剤組成物は、主剤に、潤滑向上剤、防錆剤、抗菌剤、消泡剤、油分離剤らの機能添加が可能な添加剤を配合したものが挙げられる。 As an example of a possible form of the water-soluble unit dose metalworking oil composition, as shown in FIG. 1, the water-soluble packaging container 2 used for the water-soluble unit dose metalworking oil composition 1 of the present invention may have a perforation 3, and may have a configuration in which it has a plurality of enclosed parts and can be individually cut out at the perforation 3. The water-soluble unit dose metalworking oil composition 1 of FIG. 1 has a compartment 4 that encloses the main amount (large volume) of the water-soluble metalworking oil composition, and a compartment 5 that encloses a small volume of the water-soluble metalworking oil composition of the same components for fine adjustment. Examples of water-soluble metalworking oil compositions include those that are blended with additives that can add functions such as lubrication improvers, rust inhibitors, antibacterial agents, defoamers, and oil separators to the main component.
図2に示すように、ミシン目3で分けられた水溶性金属加工油剤組成物を封入するための各区画6,7,8,9は各々異なる内容量であってもよく(例えば、区画6は500ml、区画7は300ml、区画8は200ml、区画9は100ml)、その内容量の組み合わせで、所望の投入量を調整することができるように構成してもよい。 As shown in FIG. 2, each of the compartments 6, 7, 8, and 9 for enclosing the water-soluble metalworking oil composition separated by the perforations 3 may have a different capacity (e.g., compartment 6 is 500 ml, compartment 7 is 300 ml, compartment 8 is 200 ml, and compartment 9 is 100 ml), and the desired amount of filling may be adjusted by combining the capacity.
図3には、ミシン目で切り離すことができる独立した2つの区画10、11を有する本発明の水溶性単位用量金属加工油剤組成物1が示されており、2つの区画にはそれぞれ主剤と添加剤が封入されている。 Figure 3 shows a water-soluble unit-dose metalworking oil composition 1 of the present invention having two independent compartments 10 and 11 that can be separated by a perforation, each of which contains a base agent and an additive.
図4は、複層構造の水溶性単位用量金属加工油剤組成物1を示し、10は外側の区画、11は内側の区画である。例えば外側の区画10に主剤を封入し、内側の区画11に添加剤を封入した場合、主剤が先に放出され、その後に添加剤が放出される。例えば、内側の部分のフィルム材料の厚みを厚くし、外側の部分のフィルム材料の厚みを薄くすることで、主剤と添加剤の溶解に時間差を設けることができる。 Figure 4 shows a water-soluble unit-dose metalworking oil composition 1 with a multi-layer structure, with 10 being the outer compartment and 11 being the inner compartment. For example, if the base agent is enclosed in the outer compartment 10 and the additive is enclosed in the inner compartment 11, the base agent will be released first, followed by the additive. For example, by making the thickness of the film material in the inner portion thicker and the thickness of the film material in the outer portion thinner, a time difference can be created in the dissolution of the base agent and the additive.
また、水溶性単位用量金属加工油剤組成物を保管、輸送のために梱包体とする場合、天井面と底面と4つの側面を有する箱体に、水溶性単位用量金属加工油剤組成物の間に保護シートを配置して、水溶性単位用量金属加工油剤組成物同士が互いに接触しないように積み重ねて収容することができる。例えば、図5に示すように、シート状の本発明の水溶性単位用量金属加工油剤組成物1を箱体12に積み重ねて保管、輸送のために梱包体とする場合、水溶性単位用量金属加工油剤組成物1の間にクッション用の保護シート13を挟み、これらの水溶性単位用量金属加工油剤組成物1が互いに直接接触することのないようにすることで水溶性単位用量金属加工油剤組成物1の破損を防止することができる。保護シート13としては、アルミニウム製のシートが挙げられる。 In addition, when the water-soluble unit-dose metalworking oil composition is packaged for storage and transportation, it can be stored in a box having a ceiling, a bottom, and four sides, with protective sheets between the water-soluble unit-dose metalworking oil compositions, stacked so that the water-soluble unit-dose metalworking oil compositions do not come into contact with each other. For example, as shown in FIG. 5, when the sheet-shaped water-soluble unit-dose metalworking oil composition 1 of the present invention is stacked in a box 12 to be packaged for storage and transportation, a cushioning protective sheet 13 is sandwiched between the water-soluble unit-dose metalworking oil compositions 1 to prevent these water-soluble unit-dose metalworking oil compositions 1 from coming into direct contact with each other, thereby preventing damage to the water-soluble unit-dose metalworking oil composition 1. An example of the protective sheet 13 is an aluminum sheet.
本発明を使用することによって、所望濃度の水溶性金属加工油剤を調整することができる。例えば第一の使用形態において、所定濃度、所定封入量に設定した本発明の水溶性単位用量金属加工油剤組成物の単位用量物を用意し、前記単位用量物を貯水タンク又は水溶性金属加工油剤使用液へ投入し、所望濃度の水溶性金属加工油剤組成物の希釈液を製造することができる。 By using the present invention, it is possible to prepare a water-soluble metalworking oil of a desired concentration. For example, in the first mode of use, a unit dose of the water-soluble unit dose metalworking oil composition of the present invention set to a predetermined concentration and a predetermined amount is prepared, and the unit dose is poured into a water storage tank or a water-soluble metalworking oil solution to be used, thereby producing a diluted solution of the water-soluble metalworking oil composition of a desired concentration.
第二の使用形態において、所定濃度、所定封入量に設定した本発明の水溶性単位用量金属加工油剤組成物の単位用量物を用意し、前記単位用量物を水溶性金属加工油剤使用液へ投入し、水溶金属加工油剤の濃度調整を行うことができる。第二の使用形態によって、水溶性金属加工油剤全体の濃度調整を行うこともできるし、特定の成分だけ濃度調整を行うこともできる。なお、第二の使用形態において水溶性単位用量金属加工油剤組成物に含まれる成分が水溶性金属加工油剤使用液に含まれていなくても良い。そのため、もともと水溶性金属加工油剤使用液に含まれていない成分を新たに添加することで、水溶性金属加工油剤の性能を強化したり、新たな性能を付与したりすることができる。 In the second use form, a unit dose of the water-soluble unit dose metalworking oil composition of the present invention set to a predetermined concentration and a predetermined amount is prepared, and the unit dose is added to a water-soluble metalworking oil use solution to adjust the concentration of the water-soluble metalworking oil. Depending on the second use form, the concentration of the water-soluble metalworking oil as a whole can be adjusted, or the concentration of only a specific component can be adjusted. Note that in the second use form, the components contained in the water-soluble unit dose metalworking oil composition do not have to be contained in the water-soluble metalworking oil use solution. Therefore, by adding a component that is not originally contained in the water-soluble metalworking oil use solution, the performance of the water-soluble metalworking oil can be strengthened or new performance can be imparted to the water-soluble metalworking oil.
