Glass powder has strong steric resistance and can be easily dispersed in the coating. After film formation, it can increase the fullness of the coating. The crystal tran***rent primer can not only maintain the tran***rency of the varnish, but also provide good grinding performance.
Application of glass powder:
1. When adding glass powder to matte resin, the proportion of matte powder can be reduced.
2. The addition amount of glass powder is about 3% - 5%. In order to ensure tran***rency, about 5% of bright paint can be added, and about 6% - 12% of color paint can be added.
3. If there are particles in the use of glass powder, 1% dispersant can be added. The speed of dispersion should not be too fast, otherwise the color will turn yellow and black, affecting the brushing effect.
The use of glass powder is also exquisite.
Too much glass powder will float on the metal surface to form a surface glaze, affecting the weldability of the base metal. Too little glass powder can not bond the slurry and protect the conductive phase. Therefore, the addition of glass powder in the slurry is very particular.
The factors affecting weldability are also related to metal matching, holding time, welding method, welding speed and so on.
The sintering process of glass powder also requires the particle size of glass powder. The premature sintering of too fine metal glass powder and too long heat preservation time are also easy to cause surface glaze, which directly affects the welding energy.
Precautions for using glass powder:
Everything has a degree, which is also very important |
