Description
Technical Field
The invention relates to the technical field of rust removing and preventing cleaning agents for metal musical instruments, in particular to a rust removing and preventing cleaning agent for metal musical instruments.
Background
The material of piano strings is composed of a mixed alloy of iron and copper, and the chemical properties of iron oxide and copper oxide, which are formed after the elements are combined with air and undergo redox reaction, are equivalent to oxidation protection of an oxide film type for the metal itself, but the effect is not sustainable but easily worsens. However, once the original oxide film is forcibly removed by an external force, the metal is irreversibly deeply damaged.
Rust removing lubricants, such as the commonly used WD-40 rust preventing lubricant, are used in the prior art of the musical instrument industry, but have the following disadvantages: 1. the musical instrument parts with heavy rust can not be thoroughly treated; 2. the penetration and diffusion are too strong, nonvolatile components are easy to penetrate, and the nonvolatile components are easy to remain in other material components of the musical instrument to damage other parts of the musical instrument; 3. the use is inconvenient.
Deep analysis is carried out on the characteristics of the metal material of the string and the principle of rusting, wherein the rusting type belongs to pitting corrosion (the term is: pitting corrosion) in electrochemical reaction. And the ferric oxide is used as an oxide generated by ferrous ions in air and iron elements, and plays a basic role in inhibiting the corrosion process of piano strings. How to successfully remove the iron oxide impurities without damaging the original oxide film to form a new oxide film, and the oxide film can be mutually repaired with the original oxide film to really inhibit the electrochemical corrosion process of the string, so that the string can be better protected, and the method and the device for preparing the oxide film solve the problem.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a rust removing and preventing cleaning agent for metal musical instruments.
In order to solve the technical problems, the technical scheme provided by the invention is that the rust removing and preventing cleaning agent for the metal musical instrument: comprises the following components in parts by weight: 1 percent of anhydrous carboxylic acid, 30 to 40 percent of fatty acid, 0.5 percent of oxazole and 68.5 to 78.5 percent of (mixed solvent of alcohol and hydrocarbon).
As a refinement, the fatty acid is an unsaturated fatty acid.
As a refinement, the azole is BTA or TTA.
As an improvement, the alcohol is a mixed solvent containing anhydrous low-carbon alcohol, and the hydrocarbon is a mixed solvent of cycloalkane and halogenated dilute hydrocarbon.
The improvement comprises the following components by weight: 17 g of unsaturated fatty acid, 0.5 g of BTA, 30 g of a mixed solvent of anhydrous lower alcohols, and 1 g of anhydrous carboxylic acid.
Compared with the prior art, the invention has the advantages that:
the solvent has the advantages that the final finished product is colorless and nontoxic, and related irritant gas can not be generated in the using process.
Compared with a WD40 rust removal and prevention agent, the solvent is more stable in chemical property, does not have strong permeability, and can remove the rust of the strings only by means of sponge and other articles during use.
The surface of the string immediately starts to adsorb and generate the nano protective film after the solvent is used, the surface of the string feels smoother when the string is touched again, and the rough feeling caused by rust is avoided.
The solvent can remove rust, and meanwhile, dust attached to the surfaces of strings can be directly taken away, so that the effects of cleaning, derusting, rust prevention and protection are achieved, and the quality of the strings is not changed due to the treatment of the solvent.
Through a small experiment on other parts of the piano, the agent can also be used for removing rust of metal of other parts of the piano.
Sixthly, the solvent is non-aqueous, weak in volatility and strong in adhesiveness, can take effect without long time when being applied to the surface of metal, and is free of residues.
The solvent belongs to a neutral organic solution and is not easy to generate violent chemical reaction with other solutions. Therefore, the solvent can be used as a solution base, and other components with auxiliary effects can be added, so that the solvent can solve the problem of corrosion of different metals from more application angles.
The usage is simple, the dosage and the usage mode can be adjusted according to the actual conditions, and the cleaning agent can be wiped and soaked, and can remove various metal oxidation rust substances. The components have volatility, but weak permeation and diffusion, almost do not affect other material components of the musical instrument, and have high practical value and popularization value.
Detailed Description
The rust removing and preventing detergent for metal musical instruments according to the present invention will be described in further detail below.
A rust removing and preventing cleaning agent for metal musical instruments comprises the following components in parts by weight: 1 percent of anhydrous carboxylic acid, 30 to 40 percent of fatty acid, 0.5 percent of oxazole and 68.5 to 78.5 percent of (mixed solvent of alcohol and hydrocarbon).
The fatty acid is an unsaturated fatty acid.
The azole is BTA or TTA.
The alcohol is a mixed solvent containing anhydrous low-carbon alcohol, and the hydrocarbon is a mixed solvent of cycloalkane and halogenated dilute hydrocarbon.
Comprises the following components by weight: 17 g of unsaturated fatty acid, 0.5 g of BTA, 30 g of a mixed solvent of anhydrous lower alcohols, and 1 g of anhydrous carboxylic acid.
In the concrete implementation of the invention, 17 g of unsaturated fatty acid, 0.5 g of BTA, 30 g of mixed solvent of anhydrous lower alcohol and 1 g of anhydrous carboxylic acid are mixed and stirred until the whole solution is clear and transparent, thus preparing the cleanser.
In the process of developing the rust removing and preventing agent, when the rust removing and preventing agent is used for piano strings for experiments, the problems of the mutual reaction rate of metal and other chemical substances, reaction products and whether an original metal oxide film layer is damaged or not need to be considered.
According to the types of oxides generated by main metal elements contained in piano strings and the oxides generated by the reaction of the piano strings and different chemical substances, the following three experimental comparisons of rust removal and prevention are designed; the chemical solution is prepared by selecting common dilute hydrochloric acid solution, citric acid solution, oxalic acid solution, organic chemical petroleum acid solution, urotropine (solid state), non-volatile alcohol solution, ketone and azole, and mixing at a certain ratio under the conditions of stable chemical valence of each element and no chemical reaction conflict. According to different experimental results, a complete chemical reaction table and a rust removing and preventing effect graph are manufactured.
The first experimental example: the rusted string has the derusting effect in the environment of strong acid and non-volatile solution.
Experimental materials: one each of the bare strings of the piano rusted to different degrees, dilute hydrochloric acid, urotropine (solid state), a glass rod, stainless steel tweezers, absorbent paper and a 250ml beaker.
The experimental process comprises the following steps:
(1) the diluted hydrochloric acid was drained at a rate of 5% using a glass rod and slowly poured into a 250ml beaker.
(2) Solid urotropin is put into dilute hydrochloric acid solution according to the proportion of 0.1 percent. Wherein, the glass rod needs to be continuously stirred to accelerate the volatilization heat of the dilute hydrochloric acid.
(3) Three strings with different corrosion degrees are respectively put into the solution for soaking by stainless steel tweezers, and the soaking time is 1.5 hours.
(4) And (4) respectively clamping the strings by using the tweezers again, placing the strings on the laid absorbent paper, carefully covering the part soaked by the solution by using new absorbent paper after the residual dilute hydrochloric acid solution on the surface is completely absorbed, and slightly rubbing.
(5) After rubbing, the difference between the soaked portion and the original rusted portion (no soaked portion) was observed, and the experimental effect was recorded. (as shown in the following table)
Experiment example two: the rusted strings have the derusting effect in the organic acid and volatile-free solution environment.
Experimental materials: one each of the bare strings of the piano with different degrees of rust, citric acid solution, oxalic acid solution, urotropine (solid), a glass rod, tweezers, absorbent paper and a 250ml beaker.
The experimental process comprises the following steps:
(1) the citric acid solution and the oxalic acid solution were slowly poured into 250ml beakers at a ratio of 10%, respectively.
(2) Solid urotropin is respectively put into a citric acid solution and an oxalic acid solution according to the proportion of 0.05 percent.
(3) The three rusted strings were placed in two cups of the mixed solution with tweezers, respectively, for 2 hours.
(4) And (4) respectively clamping out the strings by using the tweezers again, placing the strings on the tiled absorbent paper, and after the residual solution is dried completely, coating the strings by using the clean absorbent paper, and slightly rubbing the strings.
(5) After the rubbing, the difference between the soaked part and the original rusty part of the string was observed, and the experimental effect record was made thereon. (as shown in the following table)
And (4) experimental conclusion: from the comparison of the experimental effects of the above two tables and the product of the chemical reaction equation, the effect of using the organic acid solution as the basic component for developing the rust removing and preventing agent for piano strings is more suitable than the effect of using the ordinary pure acid solution.
The main advantages are the following three types:
(1) the reaction rate of the organic acid solution and the ferric oxide is relatively slow, so that the rust removal reaction process of the solution can be controlled to a certain extent.
(2) Most of the reactions of the organic acid solution and the ferric oxide are a combination reaction and an oxidation-reduction reaction, and the effect of restoring the chemical structure of the elements contained in the metal can be achieved through the stability of reducing ions in the process of rust removal.
(3) The permeability of the organic acid solution is weaker than that of the common pure acid solution, so that the rust removal in a point-to-point and instant-to-end mode can be realized, and the secondary metal corrosion caused by strong permeability is not easy to occur.
The disadvantages are as follows: whether citric acid and oxalic acid are used, or ordinary dilute hydrochloric acid, compounds with crystal water are produced after the descaling reaction. Although crystal water belongs to a hidden structure in the atomic field and is different from common water, the hidden danger of electrochemical corrosion of the piano strings from inside to outside still exists for the piano strings along with the time.
Experiment example three: the rusted string has the derusting effect in weak acid and weak volatility environments.
Experimental materials: the piano strings rusted in different degrees are respectively one, organic petroleum acid solution, alcohol solution which is not easy to volatilize, glass rods, tweezers, absorbent paper, 250ml of beakers and azole substances (solid).
The experimental process comprises the following steps:
(1) the organic petroleum acid was slowly poured along a glass rod into a beaker in an amount of 200ml.
(2) The alcohol solution is introduced into the organic petroleum acid solution by a glass rod according to a certain proportion.
(3) Three rusted strings were soaked in the solution using tweezers for 2 hours, respectively.
(4) The piano string is taken out and placed on absorbent paper, and after 2 minutes, the string is well coated by the tight absorbent paper and is gently rubbed.
(5) After the rubbing, the difference between the soaked part and the original rusty part of the strings is observed, and the experimental effect is recorded. (as shown in the following table)
And (4) experimental conclusion: the effect of the third set of experiments compared to the first two, it can be seen that the petroleum acid and the non-volatile alcohol solution are better than the former organic acid.
The main advantages are as follows:
(1) the petroleum acid belongs to an anhydrous organic compound, and no crystal water is generated in the rust removing process.
(2) The main component of the non-volatile alcohol solution is also anhydrous alcohol organic matter, and the characteristic of weak volatilization can stabilize the permeability of the petroleum acid at a neutral level.
(3) After rust removal, petroleum acid can automatically secrete a layer of oily substance to generate an oily protective film to cover the surface of metal, so that preliminary antioxidant protection of strings is achieved.
Experimental example four: the result of the development of the rust removing and preventing agent is compared with WD-40.
In a specific experiment process, the metal of the string has certain precision, and the integral derusting area required by the string is smaller than the derusting amount generally used in industry, so that the main components of general chemical derusting such as phosphoric acid and the like cannot be directly used for reference.
The rust removal of piano strings is required to achieve an obvious rust removal effect in a short time, and toxic gas or toxic substances cannot be generated in the process of manufacturing the rust remover from raw materials. (the chemical rust removing agents such as phosphoric acid, etc. mentioned above generate toxic gas during their use) therefore, it is necessary to select a chemical substance having both catalytic and solidifying effects. The material which is used more in ordinary times and has the two attributes is urotropin. The compounds are commonly used in the medical field, catalysts, disinfectants, curing agents, and the like.
At present, in the field of piano repair and construction in the piano industry, a common rust removing and preventing agent is WD-40. In order to compare the specific use differences of the WD-40 rust remover and the related rust removing efficiency differences, except the three groups of rust remover experiments, the experimental results of the WD40 rust remover and the final finished product effect of the rust remover are compared and completely disclosed in the following table.
As can be seen from the comparison of the experimental data in the above figures, the preliminary rust removing effect of WD-40 and the rust removing effect demonstrated by the third group of experiments using the rust remover can be nearly the same. However, WD-40 in this experiment has the following disadvantages:
1) WD40 agent has a very strong permeability, and when the string is sprayed, no matter how much, or the agent is adsorbed by using a paper towel and then wiped, excessive liquid residue is easily caused on the surface of the string. Thus, for suspended piano strings, there is a particular tendency for the chemicals to penetrate into the piano soundboard and other wooden parts, thereby causing collateral damage to other parts.
2) WD40 contains a small amount of silicon as a main component. After being sprayed on the surface of the string, the agent can prevent the generation of metal rust in a short time although the agent has a certain water-repellent effect and can not remove the rust of the part if the metal is rusted due to electrochemical reaction.
3) WD40 is also highly corrosive, because of its high permeability, and the extent of local corrosion may be continuously deepened, tending to cause uncontrolled excessive corrosion of the metal.
4) WD40 has a high volatility, high lipid solubility, and also an accumulative effect, as the main component of n-ethane. Meanwhile, in terms of physiological safety and pharmacological toxicity, if the medicament is used for a long time, multiple peripheral nerve lesions are easily caused.
5) The string for removing rust by using the WD40 not only removes rust of the string, but also shows the ground color of metal. However, the metal background color is not the restoration of the color of the metal, but is the light effect of the metal surface generated by the oily nature of the solvent after the impurities on the metal surface are physically cleaned. Moreover, after the experiment, the surface of the string still shows a small part of rust mark after the string is placed in a humid environment or is artificially damaged by other special substances (such as beverage and the like).
Through the combination of the experimental analysis, the rust removing and preventing agent has the following advantages compared with WD-40:
the solvent has the advantages that the concept of green chemistry and no pollution to a human body is adopted, the final finished product of the solvent is colorless and nontoxic, and related irritant gas cannot be generated in the using process.
Compared with a WD40 rust removal and prevention agent, the solvent is more stable in chemical property, does not have strong permeability, and can remove the rust of the strings only by means of sponge and other articles during use.
The surface of the string immediately starts to adsorb and generate the nano protective film after the solvent is used, the surface of the string feels smoother when the string is touched again, and the rough feeling caused by rust is avoided.
The solvent can remove rust, and meanwhile, dust attached to the surfaces of strings can be directly taken away, so that the effects of cleaning, derusting, rust prevention and protection are achieved, and the quality of the strings is not changed due to the treatment of the solvent.
Through a small experiment on other parts of the piano, the agent can also be used for removing rust of metal of other parts of the piano.
Sixthly, the solvent is non-aqueous, weak in volatility and strong in adhesiveness, can take effect without long time when being applied to the surface of metal, and is free of residues.
The solvent belongs to a neutral organic solution and is not easy to generate violent chemical reaction with other solutions. Therefore, the solvent can be used as a solution base, and other components with auxiliary effects can be added, so that the solvent can solve the problem of corrosion of different metals from more application angles.
Compared with the traditional WD-40 rust removing and preventing agent, the rust removing and preventing agent not only can effectively remove rust on piano strings, but also can protect the strings. The compound component in the novel reagent can continuously react with the nano layer on the surface of the metal along with the prolonging of time, thereby forming an adsorption type nano-scale anti-oxidation protective film. And the density of the protective film can not change due to the influence of external force factors, and the effect of retarding the electrochemical corrosion reaction of the string metal on a microcosmic physical layer can be achieved.
Supplementary experimental example: the relation between the component content of the reagent and the rust removing and preventing effect (the proportion of the reagent is calculated by weight ratio).
In general, when the strings are rusted, the surfaces of the strings are rough and sticky, and the quality (weight) of the strings is changed, and after rust substances are removed, the quality (weight) of the strings is also changed by using a rust removing and preventing two-in-one cleaning agent, so that the timbre generated by the vibration of the strings is influenced; for this purpose, comparative experiments were carried out for the following three aspects:
because of the need of fixing the contrast condition, a soaking method is adopted; the same weight of the same kind of strings with the same corrosion degree are subjected to 1. Rust removal effect and 2. String weight loss comparison by using the same dosage of reagent and soaking time (30 minutes):
the present invention and the embodiments thereof have been described above, and the description is not restrictive, and the above illustration is only one of the embodiments of the present invention, and is not limited thereto. In summary, those skilled in the art should be able to conceive of the present invention without creatively designing the similar structural modes and embodiments without departing from the spirit of the present invention.
