Description

TECHNICAL FIELD The present invention relates to a detergent composition for removing grease, a grease removing device using the same, and a detergent composition removing method using the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease removing detergent composition and a grease removing method and apparatus using the grease removing detergent composition and a grease removing method and apparatus using the grease removing grease and the grease removing grease used in a gas insulated switchgear To a detergent composition for removing grease used in heavy equipment for automobiles and the like, and a removing method and apparatus using the detergent composition.

The gas insulated switchgear is a main protection device for power facilities installed in a power station or a substation. It is a device that protects the power system by rapidly shutting off excessive current in the event of a failure, in addition to normal opening and closing.

These gas-insulated switchgear breakers are made of semi-solid or solid grease, in which a thickener (metal soap) is dispersed in a liquid lubricating oil (base oil). Grease is applied to the gasket when it is operated for a long time, and hardening or sticking There is a problem that normal operation becomes difficult.

Therefore, in order to prevent safety accidents caused by faulty operation of circuit breaker due to hardened and fixed grease, the substation must completely remove and reapply grease once at least every 2 ~ 3 years and apply hardening and sticking, In order to prevent breaker failure due to the grease, maintenance manual has been established and strictly controlled.

Generally, grease accounts for 80 to 90% of base oil, and depending on the base oil, it affects lubricity, heat resistance, low temperature, oxidation stability, and heat resistance.

The thickener determines the properties, and the fine fibrous network structure or particles are uniformly dispersed in the liquid lubricant oil to form a semi-solid phase, and the additive imparts special performance such as oxidation stability, rust prevention property and extreme pressure property.

In other words, the lubrication mechanism and characteristics of grease are divided into lubrication by a liquid lubricant exuding from a grease netting structure and lubrication by a grease thickening agent. Since the characteristics of grease lubrication have the structure of a net-like shape Have different characteristics. Grease is lubricated in long-term non-lubrication, lubricating machines that are simple and relatively low-speed lubricating systems, have a very low cooling effect, but are more rustproof than general lubricants.

The grease does not flow by itself unless the external force is applied, and the viscosity changes with the speed at which it moves beyond a certain force. Under severe motion, the viscosity of the base oil is close to that of the fluid, and when the external force is removed, the thickener returns to its original structure and the liquid lubricant is absorbed by the mesh structure.

Causes of grease hardening and sticking are dust pollution, temperature change around breaker, oil evaporation, and corrosive gas.

Conventionally, for the removal of grease in a gas insulated switchgear (GIS) circuit breaker, mainly methylene chloride (CH2Cl2) (75-09-2) or dichloromethane (CH2Cl2) (76-09-2) Petroleum Distillates Hydrotreated Heavy Naphthenic (64742-52-5), Petroleum Distillates, Hydroteated Light (64742-47-8), Athyl Acetate (141-78-6), Propylene Oxide (75-56-9) , Solvent Naphtha, Medium Aliphatic (64742-88-7), Petroleum Distillates (8052-41-3), Mineral Oil (8012-95-1), Paraffin Wax (8002-74-2), Nonane (111-84- 2) and Carbon Dioxide (124-38-9), which is a filler.

However, such a method can dissolve and remove base oils (mineral oil and synthetic oil) that occupy 80% to 90% of the grease component, but the nonvolatile components (about 18% to 28%) And was not suitable for the fundamental removal of grease. In particular, if the grease that has penetrated into the gap between the complex circuit breaker structures can not be completely removed, there is a side effect that the newly applied grease is dissolved by the residual material and the performance is shortened. Therefore, the breaker was disassembled and the grease was removed by physical method.

In this way, removing the grease in the gas insulated switch breaker takes a long time and breaker breakdown and reassembly, which causes breaker failure.

The fraction filler is a mixture of 1,1,1,2-Tetrafluoroethane (HFC134a) and 1,1-Difluoroethane (HFC-152a). However, in Examples and Comparative Examples, they were mixed at a weight ratio of 1: 1.

The detergent composition shown above was mixed with grease to confirm the decomposition power.

The composition shown in each of the Examples and Comparative Examples was mixed with the grease shown in Table 1, and the decomposition power was evaluated. The results are shown in Table 3 below as excellent, normal, and insufficient.

 Greece A  Greece B  Greece C  Greece D  Greece E  Greece F Example 1 Great Great Great usually Great usually Example 2 Great Great Great Great Great usually Example 3 Great Great Great usually usually Great Comparative Example 1 usually usually usually Inadequate usually Inadequate Comparative Example 2 usually usually usually Inadequate Inadequate Inadequate Comparative Example 3 usually usually usually usually usually Inadequate Comparative Example 4 usually usually usually Inadequate Inadequate Inadequate Comparative Example 5 usually usually usually usually usually Inadequate

As shown in the above table, Example 1 shows excellent decomposing power against greases A, B, C and E, and Example 2 shows excellent resolving power against greases A, B, C, D and E, Example 3 shows excellent decomposition power for greases A, B, C and F. [

However, when Comparative Examples 1 to 5 are examined, it can be seen that the decomposition power is not excellent for most greases and is normal to poor. Particularly, almost no decomposition was found with respect to the grease F, and most of the grease reacted with grease to produce agglomerated impurities.

As shown in the above examples, the detergent composition for degreasing according to an embodiment of the present invention showed excellent decomposition ability against various greases. That is, since the grease removing detergent composition of the present invention dissolves all kinds of grease without forming aggregates, when the grease removing detergent composition of the present invention is applied to the circuit breaker, all of the grease applied inside the circuit breaker is dissolved It can be discharged to the outside.

1 is a view for explaining a grease removing apparatus according to an embodiment of the present invention.

As shown in the figure, the grease removing apparatus using the degreasing detergent composition of the present invention is composed of Naphtha Petroleum Hydrotreated Heavy, d-Limonnen (C10H16), ethoxy-nonafluoro butane (C4F9O-C2H5) 3-Methoxy-3-Methyl-1-Butanol; An injector (20) mounted on a discharge portion of the filling container to inject the cleaning composition; And an absorbent 30 for absorbing the detergent composition which is discharged including dissolved grease and dust sprayed on the object.

The filling container 10 filling the detergent composition is generally a storage container for storing the spraying liquid for high-pressure injection, such as a spraying device. The filling container 10 may be made of stainless steel for compressing and filling the detergent composition, but is not limited thereto, and any container having durability capable of withstanding high pressure spraying without causing a physicochemical reaction with the detergent composition It is possible.

The injector 20 for injecting the detergent composition means an injector 20 capable of injecting the injected cleaning agent composition at an injection pressure of about 5 kg / cm 2 into the outlet of the filling container 10. The injector 20 can be injected through the high pressure injection valve of the present inventor's patent No. 10-0776770 for high pressure injection and the detergent composition can be deeply introduced into the interior of the object through high pressure injection.

FIG. 2 is a perspective view showing an adsorbent of a grease removing device according to an embodiment of the present invention. FIG.

As shown in the figure, the absorbent foam 30 absorbing the detergent composition including the dissolved grease and the dust injected into the object absorbs the detergent composition and the dust and the like. The disposable absorbent 30 absorbs the detergent composition discharged from the object The nonwoven fabric layer 31 absorbing the detergent composition and the vinyl layer 32 coated on the opposite side of the nonwoven fabric to which the detergent is absorbed so that the detergent composition can be absorbed and removed by the absorbent 30 without re- .

The grease removing device of the present invention is capable of effectively removing grease because it is sprayed onto the object through the injector 20 capable of injecting the detergent composition exhibiting a strong washing force at a high pressure.

In addition, the adsorbent 30 is disposed to effectively remove the detergent composition to be discharged, while the grease removing operation is performed on a part of the object, so that other parts are not contaminated.

The present invention also provides a method for removing grease using a grease removing detergent composition, comprising the steps of filling a grease removing detergent composition into a container, applying the applied detergent composition to an object for removing grease, And absorbing the detergent composition and dust contained in the detergent composition into the absorbent.

The filling of the grease removing detergent composition into the container is a step of filling the detergent composition into a high-pressure spraying device for applying the cleaning composition to a cleaning object such as a substrate for removing grease.

The step of applying the filled detergent composition to the object for removing grease is a step of spraying the detergent composition onto the object so that the detergent composition dissolves the grease. At this time, if the cleaning agent composition is sprayed at an injection pressure of about 5 kg / cm 2, the cleaning agent can be sprayed to an object to which a high-voltage current can flow without being close to the operator, and the cleaning agent composition is deeply introduced into the complex structure , And can completely remove grease. When the detergent composition is sprayed at a high pressure and applied to an object, the cleaning apparatus of the present invention can preferably be used.

In the step of absorbing the detergent composition dissolving out the grease and the dust contained in the absorbent, the detergent composition is introduced into the structure of the object to dissolve the grease and discharged to the outside together with the dust inside. The detergent composition dissolves the grease to dissolve in the lower part, flows down through the object, and is disposed at an appropriate position, so that the detergent composition discharged from the object is absorbed into the absorbent without re-entering.

The grease removing method using the grease removing detergent composition of the present invention allows the mixture of grease and detergent composition to be discharged without re-inflow while facilitating the operation while effectively removing grease from the object.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
