I. Introduction:
Glass powder is machine amorphous hard particle powder. In the production, the raw materials are electronic grade materials such as PbO, SiO2, TiO2, etc. after being mixed, the solid-phase reaction is carried out at high temperature to form disordered structure of glass homogenate. The chemical property is stable, and its acid resistance has far exceeded that of lead oxide. However, in the expression of chemical composition, it is converted into oxide according to the usual practice, such as PbO, SiO2, etc. 。 Please pay attention to the difference.
Physical indicators:

Whiteness: ≥ 94:
Average particle size: 2.5 ± 0.5um
Specific gravity: 2.7g/ml
Oil absorption: 28 ± 2.5g/100g
Mohs hardness: 7.8
Chemical composition: silicate
II. Characteristics:
1. The glass powder has good transparency, high hardness and even particle size distribution.
2. The glass powder has good dispersibility and good solubility with other components in resin and paint system.
3. After several times of surface treatment, the glass powder is filled in the paint system. The paint film does not have blue light and has good recoat performance.
4. When used in high-grade scratch resistant finish, it can increase the hardness and toughness of the finish, improve the scratch resistance of the paint film, have the function of extinction, and improve the weather resistance of the paint film.
5. Compared with talcum powder and glass powder, they are easy to precipitate after the paint is thinned, so the anti sinking measures should be strengthened properly.
III. Application Description:
Glass powder is mainly used as crystal primer in the production of high-grade furniture. It is also widely used as decorative primer. Scope of application: polyester paint, polyurethane paint, nitrocellulose paint, alkyd paint, acrylic paint, vinyl paint, PE transparent primer, etc.
1. In the furniture paint, its transparency, thixotropy, hardness and wear resistance are very good. It is recommended to add 3-7% of the paint and 5-10% of the color paint.
2. It is suitable for plastic paint and metal paint, and the recommended dosage is 10-15%.
3. Glass powder is mainly used as crystal primer in the production of high-grade furniture, and also widely used as bottom dual-purpose paint for decoration. It is recommended to add 5% - 10%
Low temperature glass powder:
The difference between low melting point glass powder and common glass powder lies in the difference between the raw materials of its production formula and glass powder, and the excellent function of the low melting point glass powder. The low temperature melting glass powder should be different from the low temperature melting glass powder. The low temperature melting glass powder is a kind of relatively environmentally friendly material, which is mixed, melted and co crystallized under high temperature environment to produce the silicon boron oxide metal salt. It has the remarkable characteristics of ultra-low temperature melting. The common glass powder in the market is inorganic shaped hard particles, and the raw materials used in the production are heavy metal substances such as PbO, for high-temperature solid-state reaction. Homogeneous glass with disordered structure.
Performance characteristics
1. The temperature resistance is good, and the melting state can reach 560 ℃.
2. Low melting point, 480 ℃.
3. Good salt fog resistance, acid and alkali resistance and weather resistance.
3. The melting state is transparent and the brightness is good.
4. Good adhesion with metal.
Effect:
Low melting point glass powder can play the following roles:
1. It can be used as the main raw material to replace resin in high temperature coating, paint and ink.
2. The function of glass, ceramic and metal sealing.
3. Silica gel, rubber, plastic and resin materials have the synergistic effect of flame retardant.
4. As a transparent filling material for high temperature electronic packaging.
5. It can be used as a functional filler for lightning protection engineering, ultra-high voltage transmission insulation and anti electric shock materials.
6. It is used as sintering material of superhard grinding and polishing materials.
7. It is used for special crafts (artificial diamond and glass).
8. It is used as the carrier of industrial catalyst.
Application fields:
The applied products include cathode ray tube display, vacuum fluorescent display, plasma display, vacuum glass, solar collector, laser, magnetic material head and magnetic material film, DVD, VCD, microwave oven, high-grade refrigerator, disinfection cabinet, advanced washing machine, sound, automobile panel and electronic weighing instrument, etc. other fields are as follows:
1. High temperature coating for metal of barbecue, fireplace, gas furnace and combustion furnace.
2. High temperature paint and high temperature ink for microcrystalline glass, quartz glass and special glass.
3. Carrier material of special sealing electrode.
4. It is used for the manufacture of high temperature flame-retardant silica gel, flame-retardant rubber, flame-retardant plastic and other parts of aircraft, automobile and electrical appliances.
5. It is used for high temperature flame retardant resin and electronic transparent packaging materials.
6. It is used for the insulation of lightning protection engineering and the use of anti electric breakdown materials.
7. It is used for ultra-high voltage transmission insulation and anti electric shock materials.
8. Carrier material for grinding and polishing materials sintering.
9. Main raw materials for special crafts, artificial diamonds and special glass parts.
10. Used as drug carrier and industrial catalyst carrier materials.
11. It can be used as high temperature inorganic solvent material.
12. It is used for raw materials of low temperature ceramic glaze.
13. It is used for refractory as transitional bonding material.
14. It is used for special optical instrument parts and chemical instrument raw materials.
