Abstract

A kind of cleaning apparatus instruments and meters that is applicable to, the chemical jet cleaner of the instrument that is specially adapted to moving.This clean-out system is clean-out system with the Refrigerant R 113 mainly, adds a certain amount of lower boiling chemical solvents again and becomes and can spray volatilization simultaneously rapidly, thereby greasy dirt and grey absurd creature are taken away.This clean-out system is nontoxic, and is nonflammable explosive, non-conductive, non-corrosiveness, to environment for use without any pollution.

Description

A kind of chemical jet cleaner

The invention belongs to a kind of rapid-curing cutback volatilization washing composition, be applicable to the precision instrument and the component that clean normal operation.

In existing technical field, the kind of clean-out system is a lot, is used for cleaning various device and component.The simplest a kind of mode that the clean-out system solvent is cleaned is that the object to be cleaned under the room temperature is exposed in the steam of boiling solvent, vapour condensation is on the object that is cleaned, grease or other dirt are washed off, and final solvent evaporates to resemble object is placed in the solvent liquid simply from object and does not stay residue cleaning.Use the very clean washing of solvent of fluorocarbon to industrial solid surface.Especially the washing of complicated shape and the dirt that is difficult to remove are cleaned the aspect and are had been widely used.

Fluoridizing of carbon thing solvent (for example Refrigerant R 113) is aspect evaporation washing and removing, and as a kind of effectively nontoxic and non-flammable solvent, be widely used recent years.Found that Refrigerant R 113 particularly has a kind of gratifying solvent power to grease, oil are cured etc., it also is widely used in cleans electric motor, compressor, heavy metal parts, complicated accurate metal parts, printed-wiring board (PWB), gyrostat, navigationsystem, aerospace and guided missile metal device, various electrical instrumentation, dial exchanger, video and audio recording tape, cinefilm etc.At present, have been found that its mixture clean-out system that boils that some Refrigerant R 113 bases and other chemical substance are formed, for example the patent No. has been 3,573,213 U.S. Patent Publication 1,1,2-three chloro-1,2, the azeotropic mixture of 2-Halothane and Nitromethane 99Min.; The patent No. has been 3,903,009 U.S. Patent Publication 1,1,2-three chloro-1,2,2-Halothane, Nitromethane 99Min. and alcoholic acid ternary azeotropic compositions; The patent No. is 3,7,89,006 U.S. Patent Publication 1,1,2-three chloro-1,2,2-Halothane, acetone and alcoholic acid ternary azeotropic compositions; The patent No. is 81-34,799 and 81-34, and 798 Japanese Patent discloses 1,1,2-three chloro-1,2,2-Halothane, ethanol, Nitromethane 99Min. and 3-methylpentane or 2,2-dimethylbutane or 2, the mixture of the azeotropic mixture of 3-dimethylbutane; Also having a kind of patent No. in addition is that 81,109,298 Japanese Patent discloses 1,1,2-three chloro-1,2, the mixture of the azeotropic mixture of 2-Halothane, ethanol, normal hexane and Nitromethane 99Min..Use above-mentioned patent that special-purpose rinse bath or vapour degreasion (greasy dirt) equipment are all arranged, the operation of common vapour degreasion device is part to be cleaned to be immersed in one fill in the groove of boiling solvent, to remove most dirt, and then part immersed in the fresh solvent trough fill near room temperature, last again with this part in the solvent vapour on the boiling groove, solvent vapour just is condensate on the part that has cleaned, and part is sprayed solvent distillation before also can in the end washing in addition.

From above-mentioned cleaning way as can be seen: want to clean a certain equipment, then this equipment need be out of service, and this equipment can be cleaned under certain condition, also need dismantle component in case of necessity.The azeotropic point temperature of above-mentioned in addition clean-out system is higher, wants to make its quick volatilization, also need suitably improve its temperature.

The object of the present invention is to provide low, the jet cleaner rapidly that volatilizees of a kind of azeotropic point, it is specially adapted to clean under post and telecommunications equipment and the not out-of-work situation of other instrument.

The object of the present invention is achieved like this: it is according to certain weight percent by Refrigerant R 113 and Refrigerant 12, make fused back, wherein the weight percentage that Refrigerant R 113 occupied is 71～79%, and the weight percentage that Refrigerant 12 occupied is 21～29%.Also can add a certain amount of nitrogen on the basis of said ratio, wherein the percentage ratio that is occupied is 0.5～0.7%.

The invention has the advantages that:

1. selected chemical solvents chemical property is stable, and is nontoxic, and metal is not had corrosion, nonflammable explosive, non-conductive, be convenient to transportation and store, without any pollution, therefore can be used in any precision or electronic equipment to environment for use.

2. owing to boiling temperature is arranged in this clean-out system, therefore when normal temperature uses, can volatilize rapidly, thereby under equipment situation not out of service, in very short time, clean equipment by Refrigerant R 113 dissolved dirt at-28.8 ℃ Refrigerant 12.

3. adopt spraywashing instrument, instrument, thereby replaced the conventional clean mode, promptly clean with water,, also cause the equipment obstacle easily because can't reach the purpose of whole cleanings like this with hairbrush, suction cleaner and with cotton fabric.

Embodiment 1, and this clean-out system is prepared in pressure spray tank.Before can, vacuumize to make and reach certain negative pressure in the jar, the 75%(that Refrigerant R 113 is injected the weight of prepare by desired weight ratio by pump of constant delivery type is a benchmark with the volume of jar), Refrigerant R 113 will be housed, and (how the hot   of the   sea ┑ tomb gourd leg Rong Wei glad Wei of sincere wash with watercolours normal  paddy  Yi nationality palmitic acid reveals Ran to bright lofty 10～about-15 ℃; And then Refrigerant 12 injected 25% of whole preparation weight.Because Refrigerant 12 evaporating pressure height, just can pour into by self pressure, the amount of pouring into was controlled by the time.Like this, Refrigerant R 113 (freonll-11) is just fused naturally in jar with Refrigerant 12.Jar after the preparation is all identical with the structure and the using method of existing lighter jar inflator, perfume spray tube, need only during use the jet orifice of jar is aimed at a certain position of equipment that needs cleaning, press lower valve, then clean-out system is ejected into equipment rapidly and gets on, walk greasy dirt and ash erosion thing by volatile zone, do not need the purpose that can reach cleaning out of service to reach equipment.

Embodiment 2, blending process and embodiment are basic identical, just after Refrigerant 12 is poured into jar, a spot of nitrogen reinjects, the weight percent that its weight accounts for after 0.5% of jar interior gross weight of preparing is prepared is: Refrigerant R 113: Refrigerant 12: nitrogen=77%: 22.5%: 0.5%, using method is identical with embodiment 1.
