Application of precision metal cleaning agent in the coinage process

China is one of the earliest countries to use precious metals to mint coins. When precious metals were first used as currency in circulation, there was no unit of weight verified and recognized by authoritative institutions. In order to solve this problem, people invented minting technology. With the application of many high and new technologies in the coinage industry, the casting technology of precious metal commemorative coins is progressing day by day, and the level of technology is constantly improving. The mint is critical to use cleaning agents in the coinage process, which requires the use of precision metal cleaning agents, and has high requirements for precision metal cleaning agents, and has a strong ability to remove oil stains on metal surfaces. Ruibao brand RSB-105 alkaline metal cleaning agents or RSB-102 precision metals.

Example of Metal Cleaner Formulation

The mass fraction of each raw material component of 01 phosphorus-free water-based metal cleaning agent is: AESA(C12 fatty alcohol polyoxyethylene ether ammonium sulfate):BJH -1 (fatty amine, self-made):OP-10 (octyl phenol polyoxyethylene ether):M550 (halogenated dimethyl dipropyl ammonium propionyl ammonium copolymer) = 6:4:4:1 (molar ratio), and its mass ratio is 95:5 Na-CP4 (sodium salt of maleic anhydride and acrylic acid copolymer) and sodium silicate were added as builders, and the washing effect and antirust performance of 5% dilution were evaluated. The results show that the cleaning agent has strong decontamination ability and good

Application range of precision metal cleaning agent

Precision metal cleaning agent has a unique super clean precision cleaning effect, better than the traditional cleaning agent products, can adapt to different types of precision parts of the precision cleaning and achieve clean, bright and no trace effect. Can't the oil on the battery aluminum shell be cleaned? The battery aluminum shell is mainly a semi-open mouth body in the shape of a cuboid. There are three main difficulties in cleaning the battery shell: ① Do not change color after cleaning the aluminum material; ② The lotion at the bottom of the aluminum shell is difficult to soak, and it is very easy to leave oil, so the lotion needs to have a strong wetting and penetrating ability; ③ The bottom of the aluminum shell is also difficult to be easily rinsed after cleaning agent. Do not do any of the above three points

[metal cleaning agent] auto parts on the selection of cleaning agent requirements

With the rapid development of China's automobile industry, the market demand potential is huge. In the production and processing of automobile parts, the cleaning of metal parts is a very important link. With the development of parts cleaning technology and the strengthening of people's awareness of environmental protection, higher requirements have been put forward for the use of metal cleaning agents and cleaning equipment. Automotive metal parts cleaning requirements: first of all, the cleaning equipment and cleaning parts do not produce corrosion, which is the most important requirement. Secondly, the cleaning process does not produce residues, including insoluble substances, dirt, and coatings that are not conducive to subsequent processing. Next is the cleaning efficiency to be high, there is a faster clear

Purchasing experience: acidic metal cleaning agent and alkaline metal cleaning agent which is good?

There are various kinds of dirt on the metal surface, oil soluble, water soluble, metal rust, scale, dust and so on. Acid cleaning is mainly used to clean inorganic salt scale, alkaline oxides and hydroxides on metal surfaces. Commonly used acids are inorganic acids and organic acids, of which hydrochloric acid and sulfuric acid are the most widely used. On the other hand, an acid radical ion of phosphoric acid, citric acid, or the like has a plurality of coordination atoms, and can be combined with a divalent metal ion to form a chelate. The effect of acid on metal rust is mainly through acid-base neutralization reaction to convert it into water-soluble salt. Because metal rust is mainly metal oxides and hydroxides. If the acid root

How to choose aluminum cleaning agent?

In recent years, in the production process of aluminum and aluminum alloy plates and foils, in order to continuously improve the metallurgical quality, dimensional tolerance, surface finish and flatness, mechanical properties and other quality indicators to meet the needs of the market, in the melt purification, plate control, heat treatment equipment and the final finishing process have made a lot of investment, but also achieved good results. With the fierce market competition, users put forward higher requirements for product surface quality. Such as annealing macula, residual cold rolling oil, especially a large number of residual aluminum powder on the surface of the electronic foil coating plate and aluminum-plastic composite pipe, composite plate and other products have a great impact on the quality. Therefore, aluminum

What about technical dry goods and bearings that use antirust oil and return to rust?

China's existing bearing manufacturers tens of thousands of, in the world belongs to the production of bearing power and export power. However, some bearing manufacturers have corroded the bearings after using the anti-rust oil for 2-3 months, or even a few days later. Because the bearing rust caused by the compensation case is not a few! Q:A company sent a batch of high-precision bearings overseas last year. Before leaving the port, there was no problem with all the parameters. The packaging went to sea. One month later, the customer replied that the goods were rejected because of abnormal quality. Before entering the warehouse, there is no problem in all the indicators. The customer has also tested the samples. How can there be any problems? A: Send the product back to Dingjing One
