AI Technical Summary

Benefits of technology

This patented technology describes a new type of ceramics called glass-cement (G) which combines two materials: silicate cement made from quartz sand grains and calcium oxide filler. These composites have unique characteristics such as being strong when wet but also flexible or durable over time without losing their effectiveness due to cracking under stress conditions like impact loads. They make up one key component of modern tools used during construction work.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and precision of cutting processes such as millings without sacrificially increasing costs associated therewith due to increased complexity involved in manufacturing these materials.

Abstract

The invention discloses a microcrystalline glass binder, a preparation method of the microcrystalline glass binder, a superhard material grinding tool and a preparation method of the superhard material grinding tool, and belongs to the technical field of superhard material tools. The microcrystalline glass binder is prepared from, by mass, 55-65% of SiO2, 5-15% of CaO, 1-10% of K2O, 5-15% of Na2O and 5-20% of CaF2. The superhard material grinding tool is prepared through the microcrystalline glass binder, and lath-shaped anisotropic crystals exist in the microcrystalline phase of the superhard material grinding tool and are distributed in a cross mode. According to the preparation method of the superhard material grinding tool, the crystallization temperature in the sintering process is controlled, so that lath-shaped anisotropic crystals exist in the microcrystalline phase of the superhard material grinding tool and are distributed in the cross mode, and the preparation method is easy, convenient and applicable to industrial production.
