insulating special fine machinable ceramic knob roller
Reputation depends on quality, quality comes from Hard!
Machinable Glass Ceramic:
At present, there are many kinds of glass-ceramics, and the classification methods are different:
1) According to the principle of microcrystallization, it is divided into photosensitive glass ceramics and heat-sensitive glass-ceramics;
2) According to the composition of the base glass, it is divided into silicate system, aluminosilicate system, borosilicate system, borate and phosphate system;
3) According to the raw materials used, it is divided into technical glass-ceramics (using general glass raw materials) and slag glass-ceramics (using industrial and mining wastes as raw materials);
4) According to the appearance, it is divided into transparent glass ceramic and opaque glass ceramic;
5) According to the performance, it can be divided into high-temperature, corrosion-resistant, thermal shock resistance, high strength, low expansion, zero expansion, low dielectric loss, easy mechanical processing and easy chemical etching, such as glass-ceramics and piezoelectric glass-ceramics. Biological glass ceramics, etc. Glass ceramics have concentrated on a variety of excellent properties, such as high mechanical strength, wear and corrosion resistance, good oxidation resistance, excellent electrical properties, adjustable expansion coefficient, good thermal stability, etc., and have been widely used in many fields.
Good insulativity, high temperature(800°), good machinable property, can be made of rod and plate in short time.
