Quartz glass sheets, usually cut and ground from quartz glass, have a silica content of more than 99.99%. The hardness is seven grades, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance.
High temperature resistance.
The softening point temperature of quartz glass is about 1730°C, and it can be used for a long time at 1100°C, and the temperature can reach 1450°C for a short time.
Corrosion resistance.
Except for hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially the chemical stability at high temperatures is impossible for any other engineering materials.
Good thermal stability.
The thermal expansion coefficient of the adaptable glass is small, and it can withstand severe temperature changes. The quartz glass will not burst when heated to about 1100°C in water at room temperature.
Good light transmission performance.
Quartz glass has good light transmittance in the entire spectrum from ultraviolet to
infrared. The visible light transmittance is above 93%, especially in the ultraviolet spectral region, and the maximum
transmittance can reach above 80.
infrared. The visible light transmittance is above 93%, especially in the ultraviolet spectral region, and the maximum

Good electrical insulation properties.
The resistance value of quartz glass is equivalent to 10,000 times that of
ordinary glass. It is a good electrical insulating material and has good electrical properties even at room temperature.
ordinary glass. It is a good electrical insulating material and has good electrical properties even at room temperature.
Laser processing is a technology that uses the characteristics of the interaction between the laser beam and the substance to cut, surface treatment, perforate, and micromachining the glass material. As a new type of "non-contact" processing method, laser processing technology can avoid the negative effects of mechanical stress in traditional processing for difficult-to-process materials such as glass with high hardness and brittleness, and the beam size can be focused to the order of micrometers. High-precision work processing provides basic conditions.
In principle, the methods of laser cutting glass can be divided into two types:
One is the melting (evaporation) cutting method, and the other is the crack control method.
The fusion cutting method is to use the glass to have better plasticity and ductility at the softening temperature, and use a focused CO2 laser or ultraviolet laser to irradiate the softened glass surface. The higher energy density of the laser will cause the glass to melt, and then Airflow is used to blow away the molten glass to produce grooves, thereby realizing the melting and cutting of the glass.

Features:
1. High precision, strong versatility, high efficiency; small light spot, concentrated energy, small heat affected zone;
2. No contact with the processed workpiece, no pollution to the workpiece;
2. No contact with the processed workpiece, no pollution to the workpiece;
3. Safe and reliable: non-contact processing is adopted, which will not cause mechanical extrusion or mechanical stress to the material;
4. Accurate and meticulous, the processing precision can reach 0.05;
5. The cutting gap is small: the gap for laser cutting is generally 0.05-0.1mm;
6. The cutting surface of laser cutting has no burrs;
7. Small thermal deformation: The laser cutting of laser processing is thin, fast,and energy concentrated, so the heat transferred to the material to be cut is small, and the deformation of the material is also very small;
8. The punching speed is fast, the efficiency is high, a large depth-to-diameter ratio can be obtained, the hole pattern is smooth and round, and the group hole density is high.
