Sandblasting agent is a chemical agent used for surface treatment in industrial production. The following is an introduction from the aspects of composition, function, application field, and precautions for use:
Main Ingredients
Sand blasting agents are usually composed of a variety of chemical substances, common ingredients include abrasives, surfactants, corrosion inhibitors, additives, etc.
Abrasive: It is one of the main components of sandblasting agents, such as silicon carbide, aluminum oxide, etc. It has high hardness and can remove impurities, oxide scale, etc. on the surface of objects through impact and friction, achieving the effect of grinding and polishing.
Surfactants
It can reduce the surface tension of the liquid, allowing the sandblasting agent to better wet the surface of the object, enhance the contact and action between the abrasive and the surface, and help remove oil and stains.
Corrosion inhibitor: It can form a protective film on the metal surface to prevent the metal from being corroded during the sandblasting process and play a role in protecting the substrate.
Additives: including stabilizers, thickeners, etc. Stabilizers can improve the chemical stability of sandblasting agents, and thickeners can adjust the viscosity of sandblasting agents so that they can better adhere to the surface of objects during use and facilitate operation.
How it works
Through the high-speed jetting or grinding of abrasives, the surface of the object is impacted and rubbed to remove impurities, rust, coatings, etc. on the surface, so that the surface reaches a certain degree of roughness and cleanliness. At the same time, components such as surfactants and corrosion inhibitors work synergistically to protect the substrate while removing impurities, and provide good surface conditions for subsequent coating, electroplating and other processes.
Application Areas
Metal processing: used for rust removal, oil removal, and scale removal of metal products, improving the roughness of metal surfaces, and enhancing the adhesion of coatings or plating, such as pretreatment of automotive parts and mechanical parts.
Construction industry: It can be used to treat the surface of concrete, remove the floating slurry, oil stains, etc. on the surface, improve the bonding strength of the concrete surface, and facilitate subsequent decoration and renovation projects, such as tile pasting, paint painting, etc. In addition, it can also be used for grinding and processing the surface of stone to improve the appearance and texture of the stone.
Glass processing: The glass surface can be frosted to make the glass have a certain light transmittance and haziness. It is often used to make frosted glass, art glass, etc.
Plastic and rubber products: Sanding the surface of plastic and rubber products can increase the surface roughness, which is beneficial to subsequent printing, painting and other processing techniques and increases the surface adhesion.
