Transparent Quartz Glass Products

Quartz glass is a single-component glass of silicon dioxide and is generally divided into two categories: transparent quartz
glass and opaque quartz glass (fused silica). Transparent quartz glass contains only a few bubbles and has extremely high light transmittance
Optical uniformity and transparency. It is made of silicon tetrafluoride placed in a crystal box and melted at high temperature. SIO2
The content is above 99.95%, and the content of high-purity quartz glass is 99.999%. . Opaque quartz glass adopts vein quartz, quartz
Sand is used as raw material and melted at high temperature. It contains more than 99.5% SIO2.

feature:
1. 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.
The temperature can reach 1450°C in a short time.

2. Corrosion resistance
Quartz glass has little chemical reaction with other acids except hydrofluoric acid. Its acid resistance is 30
It is 150 times that of ceramics, 150 times that of stainless steel, especially the chemical stability at high temperature, is
This is impossible for any other engineering material.

3. Good thermal stability
Quartz glass has an extremely low coefficient of thermal expansion and can withstand severe temperature changes. quartz
The glass is heated to about 1100°C, and it will not burst when placed in room temperature water.

4. Good light transmission performance
Quartz glass has good light transmission performance in the entire spectral band from ultraviolet to infrared, visible light
The light transmittance is above 93%, especially in the ultraviolet spectral region, the maximum light transmittance can reach more
More than 80.

5. Good electrical insulation performance
The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical
Insulating material, which has good insulating properties even at high temperatures.

product processing

1. Multi-tool machining.
The quartz material will stick to the plate and be attracted by the electromagnet on the bench. For cutting material,
The table is slowly raised by the motor, and the blade rotates repeatedly at high speed. upon request
Customers, the machine can cut the whole material into 1-1000mm wafers. The advantage of this step is that it is dimensionally stable and less defective products
Percent. 2. Milling.
The surface of the material can be processed into plane, vertical, inclined and various grooves or shapes
Surface machining is performed by the machine's rotating milling cutter. Can also be made into spiral grooves, cams and complex threads, splines
axis.
3. Outer circle cutting.
After cutting, the parallel misalignment of the product can reach 0.01 mm. The main reason for getting an accurate product is
A computer can control the machine.
4. Edge chamfering
The edges or shapes of quartz products will be smooth and rounded. Because of this, it is not easy to crack and damage
Jungheinrich for quartz plates or other quartz products.
5. Grinding.
According to the production of products of different sizes, shapes, and precisions, different types of grinding machines are selected. in fact it is not
Fear that the resistance of the grinding will damage the product. The reason is that the resistance is too small, two in parallel
Evenly on both sides. The benefit of this step is high productivity.
6. Manual polishing.
The traditional manual grinding is replaced by high-precision quartz components provided by customers. Our own technicians
Excellent workmanship and skilled technology. They can control the accuracy deviation below 0.07mm.

7. Polishing.
A worker is polishing quartz material with a polishing wheel. Polishing wheels are made of canvas, felt and leather. this
The quartz discs are clamped by metal discs coated with polish. The quartz sheet emits dazzling light at a speed of 20m/s.

8. Quality inspection
High quality is the guarantee of our factory reputation. We have a set of scientific and strict quality control system
Whether it is raw materials, semi-finished products or finished products. The ultimate goal is to meet the requirements
client.
