Abstract
The present invention discloses a detergent composition for water-base metal parts, which basically comprises polyoxyethylene aliphatic alcohol phosphate, fatty alcohol-polyoxyethylene ether sulfate, fatty alcohol-polyoxyethylene ether, alkylolamides, penetrating agents, alkyl alcohol amine, glycol alkyl ether, sodium metasilicate, complexing agents, antifoaming agents and deionized water. The use method of the cleaning agent comprises: cleaning with an ultrasonic cleaner; washing with the deionized water; drying with hot air or in vacuum. The cleaning agent is an aqueous agent which has the advantages of high safety, no corrosion to metal surfaces and good cleaning effect and is non-inflammable and explosion proof.
Description
The present invention relates to a kind of water-base cleaning agent composition and purging method that is used for the clean metal part.
Kinescope (CPT) or typotron (CDT) are to be assembled by hundreds of part, and wherein major part is a metal parts.These metal partss all are through being stamped to form, the a lot of greases of remained on surface and other pollutent, is to transmit repeatedly stretch forming of high velocity ram machine by multi-work-station full-automatic mechanical hand as CPT or CDT with pin, anode cap and parts of electronic gun, greasy dirt is more in the course of processing, and blind hole, contaminant component complexity arranged on the workpiece.Because pin be sealing-in in the glass screen fixing high fix structural element of shadow mask frame, anode cap is the high pressure introducing element of sealing-in on the glass awl, element surface must reach extremely clean level, could under the controlled atmosphere condition, go out baroque gradient function rete in its surface growth, satisfying the specific function requirement of electron tube, so the cleaning of pin, anode cap and parts of electronic gun is that requirement is cleaned than higher precision.Because surface tension is less, and punching oil is had high dissolving power, so the original trichloroethane that all adopts of pin, anode cap and parts of electronic gun cleans.Fluorine Lyons (CFC), trichloroethane (TCA), tetracol phenixin are the fluorochlorohydrocarbon kind solvents, are referred to as ozone-depleting material (Ozone DepletingSubstance is called for short ODS).Because to have chemical stability good for it, surface tension is less, and the kauri resin value is bigger, and penetrating power is better, does not damage many advantageous characteristic such as being cleaned material and rapid-drying properties, is widely used as the clean-out system of precision optical machinery etc. so far.But the ozonosphere in these material havoc earth high-altitudes, the harm humans ecotope is the material of time limit production in the world and use.In recent years, also developed some short-term surrogates, as Hydrochlorofluorocarbons (HCFC), perfluoroparaffin (PFC) and other halogenated solvents etc.Hydrochlorofluorocarbons is that the part halogen atom in fluorine Lyons is replaced by hydrogen atom, makes the ozone-depleting in fluorine Lyons value (ODP value) reduction of diving, but it still can damage the ozone layer, and also will be eliminated to the year two thousand twenty, is no more than the year two thousand forty the latest.Some organic solvent also can be used as the surrogate in fluorine Lyons, but cleaning performance is good not as fluorine Lyons cleaning performance, and flash-point is low, inflammable, explosive, and some is also toxic simultaneously, and operating environment is had relatively high expectations.Therefore people's expectation develops that to replace the high performance non-halogen in fluorine Lyons be clean-out system, but does not have such clean-out system with excellent cleaning performance openly to report up to now as yet.
The objective of the invention is to overcome the shortcoming of prior art, a kind of nontoxic non-corrosiveness is provided, the cleaning semi-conductor of readily biodegradable or the water-base cleaning agent composition of precision metallic part.
Cleansing composition of the present invention basic composition is:

Proportion (25 ℃ of water=1) 1.00 ± 0.02
Surface-active substance content is greater than 30%
-10～+ 50 ℃ of stability are stable
The cleansing composition of preparation according to the present invention, can replace the ODS clean-out system, following advantage is arranged: this product soil removability is strong, can effectively remove mineral oil, vegetables oil, animal oil and mixing oil thereof, cleaning performance reach the ODS cleaning performance, can effectively remove the multiple punching oil and the lubricating oil on metal parts surface, the metallic surface is not had corrosion, and not damaged can substitute ODS materials such as trichloroethane and carry out degreasing, do not contain the ODS material, nontoxic non-corrosiveness does not have destruction to ozonosphere, and biological degradability is good, use and directly to discharge, easy to use, environmentally safe does not have influence to Global warming, human body is not had harm, reach advanced world standards.This product emulsification, dispersive ability are strong, and anti-soil dirt deposition capability again is good, does not produce secondary pollution, and use range is wide, and the part that High Temperature High Pressure is stamped out has splendid cleaning performance, and it is good to clean back metal parts surface brightness.This product is an aqua, and is safe, do not fire not quick-fried, euosmia invariably.
When the cleaning that is applied to various precision metallic parts such as picture tube industry, can effectively remove the multiple punching oil and the lubricating oil on metal parts surface, the metallic surface there is not corrosion, not damaged is suitable with the cleaning performance that uses ODS materials such as trichloroethane, CFC-113.
A kind of method of cleaning pollutents such as grease on semi-conductor or the precision metallic piece surface, dust, carbon deposit comprises and uses above-mentioned cleansing composition, cleans with Ultrasonic Cleaners, uses deionized water rinsing then, and hot blast or vacuum-drying get final product.
When cleaning various precision metallic part such as picture tube industry with this clean-out system, available 5～10% said composition and deionized water are mixed with scavenging solution, soak or ultrasonic cleaning in the time of 40-60 ℃, rinse well with deionized water then, vacuum or warm air drying get final product.
