Washing Of China Stud Supplier

    1. Soluble emulsion cleaner

        Soluble demulsifiers generally contain soil, organic solvents, demulsifiers, builders, desulfurizers and a small amount of water. The purpose of the water is to melt the demulsifier, which can dissolve the waste on the surface of high-precision screws, and can also leave an anti-rust film on the surface. The demulsifiers and detergents in it can grasp the vegetable oil particles and blend them into the detergent with organic solvents and oils. Emulsion cleaner is a pure oil product in the extraction state, which becomes milky white milky liquid after diluting it in water.

    1. Generate cleaner

        The generated cleaner is not the same as the standard alkaline cleaner. The difference depends on the composition. It is also a kind of alkaline cleaner. The standard alkaline cleaner is essentially inorganic, while the generator is an organic chemical agent containing an amine-based chemical substance. This product is designed to remove partial alkali residues in single-stage cleaning, and it is also a good anti-rust oil. The generated cleaning agent is used to carry out the cleaning of the medium level of difficulty, such as the quenching oil for cleaning the surface of the high-precision screw or the heat-treated polymer aqueous solution.

    1. Partial alkaline cleaner

        The partial alkaline cleaner is a mixture of builders and alkali metal salts of surfactants. It is a widely used cleaner. In addition to the foothold of each salt and surfactant, the main purpose is to ensure the actual effect of cleaning, followed by rationality. It is stipulated that the pH value of the cleaning agent is around 7. The cleaning ingredients of this type of cleaner are nickel hydroxide, aluminosilicate, sulfide, polyphosphate, borate and its organic chemical compounds.

    1. Acid cleaning agent

        It is not a reasonable way for China Stud Supplier to use acidic cleaners for removing general waste from high-precision cross headless special screws. Generally, alkaline cleaners are used. It is very reasonable to clean oxide scale and other unique appendages with acid. The well-known processing technique is acid leaching. Except for cold rolling, electric welding and heat treatment, the air oxidation of the skin layer, the surface metal oxides, rust and corrosive substances that endanger the quality of the electroplating process or the frame seal, and the water deposits can all be removed with acid. Commonly used are citric acid such as hydrochloric acid, sulfuric acid, sodium cyanide, sodium citrate, and glacial acetic acid. For the high-toughness and high-precision screw heat treatment process to the phosphating film, the key application at this stage is the first three cleaning processes, but hydrogen corrosion should be avoided. The acid-base agent should contain a basic acid and a desulfurizer to avoid corrosion of the surface of high-precision screws, and a surface activator to improve the cleaning ability.
