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.

- 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:Extruded board fire B1, B2 grade material how to distinguish
- Extrusion board fire B1, B2 grade material distinction: B2 level for the slow combustion level, that is, after the fire will not become larger, and the drop will not ignite the filter paper; B1 level from the asphyxia, that is, leave the fire After the automatic extinguished, or 10 seconds off. Extruded board is extruded polystyrene insulation board, it is polystyrene resin as raw materials with other raw materials and additives, through a special process of heating at the same time into the catalyst, and then continuous extrusion (XPS), XPS has a perfect closed-cell honeycomb structure, this structure allows the XPS board has a very low water absorption. It is known as the thermal insulation with extruded polystyrene foam (XPS) (Almost no water absorption), moisture-proof, airtight, light, corrosion resistance, low thermal conductivity, high pressure resistance, anti-aging (normal use almost no aging decomposition), long life, low thermal conductivity Energy saving and environmental protection insulation materials. Due to the continuous extrusion caused by the tight closed-cell structure.
