Liquid substance protecting the surface of metal, non-metal or composite materials
Protective agent refers toMetalThe liquid substance protected on the surface of non-metallic or composite materials makes the material surface have some special functions, such as acid and alkali resistance, salt fog resistance, water resistance, abrasion resistance, solvent or special gas resistance, aging resistance, ultraviolet resistance, high temperature resistance, low temperature resistance, vibration resistance, skid resistance, friction reduction, anti-static, moisture prevention, antifouling, insulation, conductivity, heat conduction, heat insulation, flame retardancy, etc.
Protective agent is a substance that can prevent the developer in the solution from being oxidized or reduce its oxidation degree.It has the chemical property that is easier to be oxidized than the developer, can retard the oxidation of the developer, and has the effect of limiting the oxidation within the scope of the protective agent by preferentially reacting with the oxygen in the air.It can protect the reducing ability of developer, enhance the stability and storage resistance of developer, and prevent developer oxide from polluting sensitive materials.The most commonly used chemical is sodium sulfite, which also includes potassium bisulfite and sodium bisulfite.[1]

Automobile protective agent refers to the product that has the function of polishing and protecting the interior and exterior decoration of automobiles.There are many categories of protectants, generally including leather, chemical fiber, velvet, carpet, plastic parts, rubber skirts, bumpers, doors and windows, car hubs, exhaust pipes, etc.The use of protective agent plays an important role in automobile maintenance. Frequently use protective agent to decontaminate, clean and polish all kinds of trims and parts, which can make the trims inside and outside the vehicle clean, beautiful, bright, anti-aging, anti-corrosion and prolong the service life.There are many kinds of protectors, such as leather polish protector, leather polish protector, chemical fiber protector, velvet protector, carpet protector.Tire polish, engine polish, apron protector, etc.These protective agents can form a protective layer on the surface of the product and can renew the surface.However, when using these protective agents, attention should be paid to the use method, and they should not be mixed.
