Paint and Ink
Whether in solvent-based coatings or water-based coatings, effective equipment should be used.
The functions of gas-silicon include: thickening, thixotropy, anti-current hanging, and increasing the stability of pigments. Hydrophobic silica will have some corrosion resistance.
The types of coatings are generally divided into: wood paint, metal paint, anti-corrosion paint, coil paint, Marine paint, plastic paint and so on. The resins used include: alkyd, epoxy, acrylic, polyurethane these several categories.
Plastics Industry
Whether hydrophilic or hydrophobic fumed silica is mainly used as an additive in polymers, polymer composites and engineering plastics to provide rheological control, thixotropic effect, prevent color channelling, anti-adhesion, anti-settlement, as a flow aid for powdered polymers and resins, or to give the system a stronger waterproof effect. In powdered and granular polymers and resins, fumed silica enhances the free flow of the product and prevents caking, controlling the electrostatic charge of the product, and also acts as a processing aid during the melting of the product. In elastomers, fumed silica and provides reinforcing effects, as well as hardness, mechanical strength, and heat stability.
Composite industry
The main reuse of gas-silicon in various composite materials includes: controlling the rheology of the system, increasing the wear resistance and hardness of the system, increasing the fluidity of various powders, and using hydrophobic gas-silicon to achieve a fixed dielectric property, moisture control and hydrophobicity. Planetary agitators, belt mixers, bead mills, high-speed mixers and kneaders are usually used to achieve the mixing of gas silicon and other raw materials.
Battery
Fumed silica in the field of batteries is mainly used in the preparation and production of colloidal batteries. The main functions of gas-silicon in colloidal batteries are: thickening, thixotropy, colloidal structure. It can increase the charge and discharge times of the battery, the storage time of charge and discharge and avoid the leakage of battery fluid.
