High borosilicate glass introduction:
High borosilicate 3.3 glass is heat-resistant glass, thermal expansion coefficient is 3.3 0.1×10-6/K, is a kind of glass based on sodium oxide (Na2O), boron oxide (B2O2), silicon dioxide (SIO2). The content of borosilicate in the glass composition is high, respectively, boron: 12.5~13.5%, silicon: 78~80%, so it is called high borosilicate glass. Acid, alkali and water resistance, excellent corrosion resistance, with good thermal stability, chemical stability and electrical properties, so it has chemical erosion resistance, thermal shock resistance, good mechanical properties, high temperature resistance and other characteristics.
Specific physical and chemical properties are as follows:
Application: High borosilicate 3.3 glass is widely used in chemical industry, aerospace, military, family, hospital and other fields.
1. Household appliances (glass panel inside oven, microwave tray, stove panel, etc.)
2. Environmental Engineering, Chemical Engineering (resistant lining, chemical reactor, safety goggles)
3. Lighting (spotlights and protective glass for high-power flood lighting fixtures)
4. Solar power generation (solar cell substrate)
5. Precision instruments (optical filters)
6. Semiconductor technology (wafer, display glass)
Seven. Medical technology Bioengineering
8. Safety protection (bulletproof glass)
Processing scope:
1.According to customer requirements according to the size processing, product thickness 2mm - 50mm
2. Subsequent deep processing ① cutting ② chamfering ③ edging ④ polishing ⑤ drilling ⑥ screen printing ⑦ toughening
