Strong metallic paint remover widely used in Europe and the United States

The paint on the metal surface, because the paint and metal surface bonding is stronger, so the general detergent can't do anything. If the use of gasoline, kerosene and other washing, not only poor washing effect, and these substances are very easy to burn, prone to fire, often cause undue losses. This paper introduces a general paint remover for metals, which has excellent properties. It is widely used in Europe and the United states. The paint remover has the advantages of high paint removal ability, quick paint removal and no corrosion to the metal surface; the agent is not easy to burn and is safe to use. The agent is used as a general metal paint remover.
Aluminum copper plating bath
In the metal material, aluminum material is favored because of its light weight and low price. But it is difficult to weld on aluminum surface. If a layer of copper can be plated on the surface of aluminum, it can not only solve the above difficulties, but also increase the decorative and conductive properties of aluminum. The copper plating is carried out in three steps, that is, chemical immersion zinc, pre copper plating and copper plating. With this agent, the copper plating on aluminum is stable, the process is simple, the coating is firm, smooth and smooth, the service life is long, and it has weldability. It is used for the copper plating on the surface of aluminum and its alloy and its products.
Cyanide free silver plating bath
Silver coating is mainly used in instrument manufacturing and electronic industry to improve the conductivity of wire, avoid contact point oxidation and reduce contact resistance. Also for the silver plating layer of protective and decorative such as jewelry, badges, tableware, musical instruments, and special purposes such as lamp, mirror, mirror, searchlights, medical equipment. In addition, various kinds of chemical utensils and instruments are also used for silver plating in order to keep them from corrosion in alkaline solution. The silver plating solution is stable and has strong bonding with the substrate. The dispersion and deep plating ability of the silver plating solution are better than that of cyanide silver plating. The coating is bright and fine without coarse grains. The plating solution is non-toxic and has no environmental pollution. This is much better than cyanide silver plating. Mainly used for silver plating of copper and copper alloy.
Nonferrous Metals cleaning agents widely used at home and abroad
The surface of non-ferrous metals and their products can easily adhere to oily substances in the process of production and processing. Cleaning these substances has always been one of the difficult problems in industry. The cleaning agent for non-ferrous metal grease are: cleaning agent based on surfactant, solvent based cleaning agent and alkaline substance based cleaning agent three. Based on surfactant cleaning agent is not damage the metal pumping activity can make a small amount of grease, and disperse from the metal products, the disadvantage is the hard water resistance is poor, the actual use, often to add a small amount of alkaline substances as additives to improve the washing effect. Solvent cleaning agent has the advantages of convenient cleaning, but high selectivity to dirt. For example, polar heavy fatty acids and other dirt on non-polar kerosene, the dissolution is not strong. The cleaning agent based on alkali is generally easier to clean under the condition of less absolute fouling, and the price is cheap, but the permeability of alkali solution is poor, and surfactant is often added to make up for its deficiency. As mentioned above, the first method is the same as the third method, but only the amount of surfactant (or alkaline substance) is different. This agent is prepared by adding surfactant and alkaline additives. The agent at home and abroad of nonferrous metal cleaning grease is widely used. Two propylene glycol monomethyl ether and twelve sodium alkyl benzene sulfonate were used as surfactants in this agent. The active agent has strong detergency and does not damage the metal surface. Adding alkaline substances such as sodium phosphate three and sodium silicate to improve the dispersing and penetrating ability of detergent. Sodium silicate has colloid property, and it is good for pH value of stable cleaning agent and hard water resistance. The agent for the cleaning of oil surface of non-ferrous metals, can also be used for aluminum or steel products to grease.
Former Soviet scientists developed dairy equipment decontamination detergent
Milk, cheese and other dairy processing equipment cleaning, decontamination, has been considered more difficult. Cleaning with ordinary washing not only has poor cleaning effect, but also can not be disinfected because it contains no sterilization and sterilization ingredients. If the purpose of disinfection is reached, disinfection must be carried out again. The procedure is complicated and the cost is high. Here is a kind of detergent which can clean and disinfect double energy. The agent was developed by scientists in the former Soviet union.
Zincate zinc plating
At present, the methods of zinc plating on metal include acid zinc plating, cyanide zinc plating, zincate zinc plating, etc.. Each of these methods has its advantages and disadvantages. Acidic zinc plating has the advantages of low cost, stable electrolyte, high current efficiency and low toxicity. The disadvantage is that the coating has rough crystallization and poor dispersion ability. The advantage of cyanide zinc plating is that the electrolyte is easy to prepare and no ash is electroplated. The drawback is that the toxicity is great. Zincate zinc plating does not have the above shortcomings, especially the toxicity is small, the operation is relatively safe. The electrolyte of this agent is simple, easy to adjust, has good dispersion ability, and the crystallization of coating is more detailed. Less toxicity, relatively safe operation. The disadvantage is that it is easy to form sponge deposits, so it is necessary to use high temperature to obtain good coating. Zinc plating for metal parts (wire, strip, etc.).
Widely used antirust cutting fluid in Europe, America and other countries
The machining of metal surface with cutting fluid can improve the surface finish and reduce the machining cost. In the process of metal cutting, high temperature will cause the workpiece surface sintering, melting, affecting the processing quality and processing efficiency, resulting in waste products and defective products. Therefore, metal cutting fluid plays a very important role in the cutting process. Generally, the cutting fluid with good quality should be equipped with cutting fluid
