Manufacturers produce borosilicate 3.3 heat-resistant glass（Optical lens）
Product Introduction
Borosilicate glass 3.3 is a type of glass that has become increasingly popular in recent years, due to its excellent thermal and chemical resistance properties. It is composed mainly of silica, boric oxide, aluminum oxide, sodium oxide, and other oxides. This specific combination makes it ideal for use in optical lenses as well as various types of laboratory equipment. Borosilicate 3.3 glass can be used as optical lens for cameras and other equipment.At the same time, its wear resistance is also very prominent.
Borosilicate Glass Optical Lenses are used for a variety of applications such as microscopy and telescopes. The combination of the borosilicate glass material with the precision-made optics allows for superior performance when compared to standard plastic or acrylic lenses. Additionally, Borosilicate Glass Optical Lenses provide increased clarity and color fidelity which helps reduce eye fatigue during extended viewing sessions.
The composition of Borosilicate Glass 3.3 makes it particularly suitable for high temperature use without compromising on strength or durability; this property can be beneficial when creating optical lenses which require higher temperatures during production processes than what traditional glasses can handle without cracking or melting under pressure.

Advantages
High borosilicate 3.3 glass is high-temperature resistant glass, heat-resistant glass and temperature difference resistant glass. The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K, is a glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as the basic components. The content of boron and silicon in the glass composition is relatively high, namely, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%.
The expansion coefficient will affect the stability of glass. The expansion coefficient of borosilicate 3.3 heat-resistant glass is 0.4 times that of ordinary glass. Therefore, at high temperature, borosilicate 3.3 heat-resistant glass still maintains excellent stability and will not crack or break.

- Q:Building ceiling material fire rating
- Divided into four grades, non-flammable, flammable, flammable, flammable
- Q:Short point is to do hand copy
- Several common fire fighting methods: 1, furniture, bedding and other fire: the general use of water fire. With water around the items such as the basin and so on to the flame on the water, but also the water pipe connected to the faucet sprinkler fire; at the same time the burning point near the combustible humidification. But the oil, electrical fire can not use water to fire. 2, electrical fire: household appliances or lines on fire, we must first cut off the power, and then dry powder or gas fire extinguisher, can not directly splash water to prevent electric shock or electrical explosion wounding. 3, the TV fire: TV in case of fire, never water, you can cut off the power, with a quilt to cover it. Fire, only from the side close to the TV, to prevent the camera tube explosion wounding. If the use of fire extinguishers fire, should not be directed to the TV screen, so as to avoid the sudden cold after the heat and explosion. 4, the pan fire: the oil pan should quickly shut down the stove gas valve, directly cover the lid or cover with a wet cloth, but also to the pot put the chopped vegetables to cool the fire, the pot smooth from the fire, After cooling to open the lid, do not pour water to the oil pan. 5, gas tank fire: use wet bedding, clothing and other cover fire, and quickly close the valve. 6, the body of the fire, do not run around, can be used to roll or heavy clothing to suppress the flames. Wearing a wet towel, handkerchief and so cover your nose and mouth, try to make the body close to the ground, bending or creeping forward.
- Q:If you really have this kind of material, please tell me, if you can tell where you can find it really is so much more thanks
- Ice, I told you! By the way tell you can be found in the fridge! you are welcome! Help others for the sake of happiness Well
- Q:Class A fire door Doors filled with refractory material
- Different. Most of the perlite fire board, individual foam door core board, vermiculite fire board, MC material and so on fire protection materials.
- Q:What is the thickness of the thin fire retardant paint brushing each time?
- Thin-type fire retardant coatings on the market for water-based paint, do not rule out the possibility of oil paint. Generally there are two kinds of spraying or brushing. Spraying thickness is generally between 05-1mm. According to the different characteristics of the coating to determine the construction process.
- Q:What is the bulk density of rock wool A grade fireproof material?
- General 120KG / cubic meter
- Q:What is fireproof material? Fireproof material and insulation materials, refractory material is the same thing?
- Fireproof material is to add a kind of anti-tripod foot with a large number of high-temperature, heat-resistant, flame-retardant properties of the material or itself has a high temperature, heat and flame retardant properties of the material. And insulation materials and refractories are not a concept. Insulation material refers to the insulation, insulation of a class of materials. Refractory material is a kind of high temperature resistant material, which is one of the four traditional inorganic nonmetallic materials.
- Q:Performance and Difference of Rockwool and Glass Fiber Fireproof Materials
- Rock wool and glass wool fire rating are all A-level rock wool high temperature of 800 degrees glass wool high temperature 450 touch tiger whip mortar Zhuang Huan Biao cloth wave density rock wool relative weight of some glass wool bulk light from the waterproof performance or glass wool better some
- Q:Fire safety basic knowledge training content
- What is the meaning of the signal disc valve action?
- Q:What is Class A Fire What is Class B Fireproof?
- Now the state must use A-class fire B-class can not be used
