For welding electrodes,
Mica powder is recognized as a flux coating on metal wires in the production of welding electrodes. Mica is added to the electrode coating flux as an arc stabilizer, weld pool protector, flux, slag conditioner, adhesive, extruder, and pigment. Potassium also helps to relight the electrodes after a current interruption. The mica coating offers two types of protection. Firstly, it is used to form a fusible slag and good seal in the melting zone of the arc. Second, it resists the effects of heat, gases and other ambient atmospheric oxidation. In fact, the nature of the mica coating greatly affects the quality of the welding electrode.

For plaster plasterboard,
Large amounts of mica powder are used as fillers in lightweight precast gypsum wallboard, floor slabs, and building panels. Mica is lightweight, refractory, free flowing, chemically inert and non-abrasive. Sound suppression, good thermal and thermal insulation properties, dimensional stability, and very low water absorption are some of the other salient features. All these satisfactory properties make mica an ideal and reasonable filler in the gypsum board industry.

for
Wallboard Cement Compound, Mica Powder is a cost-effective filler and extender for wallboard cement compounds. Used to fill and finish seams, seams, and defects in gypsum wallboard, adjacent boards, and other structures. Mica as a toughening agent can improve compound processability by preventing cracking, eliminating spallation, and reducing shrinkage. Mica particles are insoluble and impermeable to water, so they can protect the walls from absorbing moisture. It can also provide smooth edges and decorative texture of the wall.

For asphalt products,
Considerable tonnage of mica powder is used as an inert filler in asphalt and asphalt compositions. Mica is applied as a surface coating on rolled asphalt roofing felt, shingles, and wet grit to increase hardness and mechanical stress and weatherability. Mica prevents adhesion to adjacent surfaces during manufacturing and storage. Due to the mica plate-like structure, the coating is not absorbed by the newly manufactured roof. It gives a shiny appearance and increases the durability of roof products. Compared to other materials, mica has the above purpose.

For automotive audio products,
Mica powder is widely used as a filler in acoustic compounds in the manufacture of automotive parts, providing comfort and well-being for drivers and passengers by controlling noise and blocking the heat generated by insulated commercial vehicles. Mica's seismic, muffler, and thermal protection cannot be ignored. In addition, adding mica to audio products can significantly improve properties such as strength, stiffness, and dimensional stability. It also reduces flammability and warpage.

For automotive plastic
The most widely used mica powder is for cars. Mica is used as a reinforcement for lightweight plastic automotive parts such as dashboards, fenders, seatbacks, panels and ignition systems. Mica reinforced plastics have improved mechanical properties, higher strength, stiffness and stiffness. It also has high thermal dimensional stability, heat resistance, reduced warpage, and the best surface properties of any filled plastic composite.

For brake lining,
Mica powder is used as a friction material in non-asbestos brake linings, brake pads, brake shoes, brake discs and clutch linings. Mica's high heat resistance reduces heat flow and keeps the brake drum cool. Mica particles are stronger than iron, strengthening and hardening the product, preventing microcracks and minimizing warpage. The mica flake structure tends to lock together under compression during processing to form an effective and excellent surface. Mica's benefits are believed to reduce noise and provide positive environmental protection.

For rubber and tires,
Mica powder is very useful as an anti-stick and anti-stick agent in the manufacture of rubber tires for cars, motorcycles and aircraft. Used as a dust remover and release agent to prevent tire rubber and tire carcass from adhering to the mold during vulcanization. Mica prevents the transfer of sulfur and allows air and moisture to escape during curing, forming a uniform structure. As a rubber additive and filler, mica can improve the elasticity, hardness, tensile strength and tear resistance of rubber products.

For plastic,
Mica powder is widely used as a functional filler in the plastics industry to provide fortification. The addition of mica results in high heat resistance, barrier against chemical attack, improved flexural strength and stiffness, very low water absorption, low shrinkage and expansion coefficient, and improved dielectric and surface properties of plastic composites You. In engineering thermoplastics, consumption is dominant.

For paint,
Mica powder is an important component of fillers and fillers in coating production. The mica plate structure enhances the protective coating of paint. The addition of mica helps to suspend, reduce cracking and delamination, prevent shrinkage and shearing of the coating, increase the resistance of the coating to moisture permeability and atmospheric aging, enhance the performance and brighten the color pigment tint . The use of mica in paints is widely established due to its functional properties.

For extinguishing agents,
Mica powder is mainly used and added to the formula to allow the powder in a dry fire extinguisher to flow freely. Mica is fire resistant and prevents the powder mixture from tightly clogging the can.

For firebricks,
Mica powder is used in the production of insulating bricks, slabs, blocks and tiles due to its excellent thermal and insulating properties. Mica bricks can safely withstand extreme temperatures of 1000 ° C, thus minimizing heat loss, minimizing energy consumption, reducing operating costs, increasing furnace efficiency and improving furnace conditions Can be improved.
