Abstract
The invention discloses a metal degreasing agent which comprises the following raw materials in percentage by mass: 8-12% of potassium silicate, 6-10% of potassium pyrophosphate, 4-6% of fatty alcohol polyethenoxy ether, 3-4% of decanol polyethenoxy ether potassium sulfate, 1.5-3% of polyoxyethylene polyoxy propylene monobutyl ether, 0.2-0.4% of benzotriazole and the balance water. The metal degreasing agent has the following properties: strong cleaning power: the experiment proves that the cleaning power (4%, 65 DEG C) reaches more than 99%; weak corrosivity: the experiment proves that the corrosivities to cast iron and brass are respectively Level 0 on the appearance, wherein the corrosion amount of cast iron is 1.12mg, and the corrosion amount of brass is 0.56mg; strong antirust capacity: the antirust capacities for singlechip and multiple chips are respectively Level 0; high product stability: the product can not easily delaminate; favorable compatibility with a cooling medium and refrigerant oil: the metal degreasing agent is suitable for cleaning parts of refrigerating compressors; and no toxicity or harm to human bodies, and high safety: the metal degreasing agent does not contain any harmful substances for human bodies.
Description
Technical field
The present invention relates to a kind of clean-out system, particularly a kind of metal degreasing agent that is applicable to that skimming treatment needs in the compressor production process.
Background technology
In the production and the course of processing, the surface of workpiece inevitably can be contaminated, for this reason, needs to use the corresponding cleaning agent to clean, to guarantee or to improve the quality of product.The purpose of cleaning is generally except that degrease, organic residual and pigment dirt and tectum and oxidizing substance.
The precision metallic part is the vital part of complete electronic set and precision optical machinery product, and its processing and assembling are relatively more accurate, and is very responsive to pollutent.The cleaning quality of precision metallic part directly has influence on complete electronic set and precision optical machinery performance of products and safety.Compressor is as a kind of precision optical machinery product, and its cleaning performance directly influences the quality of product.Because of degree of cleaning following to the influence of complete machine quality:
A) cause compressor performance bad
B) cause the compressor impurity content exceeding index
C) cause compressor stuck
D) cause compressor to be scrapped
E) cause compressor because of lubricating the bad or overload of bad performance
F) destroy refrigerator oil
G) destroy refrigeration agent
In refrigerator, compressor of air conditioner manufacturing, external grease-removing agent product monopolizes China's grease-removing agent in the market that compressor is made industry at present, and costing an arm and a leg of import grease-removing agent increases the compressor manufacturing cost.And the grease-removing agent of domestic production generally has following defective: pollutent is arranged: cause compressor performance bad, cause compressor stuck, cause compressor to be scrapped; Rustless property is poor, is prone to get rusty, cause the compressor impurity content exceeding index, cause compressor performance bad, cause compressor to be scrapped; Be difficult for rinsing residue arranged: destroy refrigerator oil, cause compressor because of lubricated bad, performance is bad or transship, destroy refrigeration agent, cause that compressor is scrapped etc.The metal degreasing agent that domestic shortage is high-end.
Summary of the invention
The object of the present invention is to provide a kind of metal degreasing agent.
The technical scheme that the present invention taked is:
A kind of metal degreasing agent, be made up of the raw material of following mass percent: potassium silicate 8～12%, potassium pyrophosphate 6～10 %, AEO 4～6 %, decyl alcohol Soxylat A 25-7 vitriolate of tartar 3～4 %, polyoxyethylene polyoxypropylene monobutyl ether 1.5～3 %, benzotriazole 0.2～0.4%, surplus are water.
Metal degreasing agent of the present invention has extremely strong cleaning force, and cleaning force (4%, 65 ℃) experiment reaches more than 99%;
A little less than the metal degreasing agent corrodibility of the present invention, the corrodibility of cast iron and brass is tested outward appearance be 0 grade, etching extent cast iron is that 1.12mg, brass are 0.56mg;
Metal degreasing agent of the present invention has strong antirust ability, and monolithic, lamination are 0 grade;
Metal degreasing agent of the present invention has good product stability, is difficult for layering;
Metal degreasing agent of the present invention and refrigerant, the refrigerator oil consistency is good, is suitable for the cleaning of refrigerant condenser component;
Metal degreasing agent of the present invention does not contain harmful material, and to human non-toxic, harmless, security is good.
Embodiment
