CAS 7440-42-8 is a black or dark brown powder. When it is oxidized in the air, it will prevent the internal boron from continuing to oxidize due to the formation of a boron trioxide film. It can react at normal temperature Amorphous Boron Powder is insoluble in water, powdered boron is soluble in boiling and most molten metals such as copper, iron, manganese, aluminum, and calcium.
1. Boron fiber has high strength (breaking strength at room temperature is 2744 ~ 3430MPa) and high modulus of elasticity (39200 ~ 411600MPa), which is an excellent reinforcing material.
2. Composite materials made of boron fiber with metal (aluminum, magnesium, titanium, etc.), various resins (epoxy resin, polyamide, etc.) and ceramics are excellent high-temperature structure materials.
3. Reinforcement ceramics made of titanium boride have excellent abrasive resistance and high toughness (up to 10 MPa�·m 1/2 or more), which are used to manufacture conductive parts for heating equipment and ignition devices.
4. Used as a deaerator in the metallurgical industry and an additive to improve the structure of metal grains.
5. Boron-cast iron is widely used in automobile, tractor, machine tool and other manufacturing industries.
Main USES of PVB film extrusion line:
1. PVB automobile safety glass film production line: PVB film is mainly used as the intermediate layer of automobile front windshield
2. PVB building glass intermediate film production line: PVB film is mainly used as the intermediate layer of high-rise building glass
3. PVB solar film production line: PVB film is used for packaging solar film batteries
Suzhou Gwell machinery CO. LTD. 's PVB film production line is a reliable brand. China's top three PVB manufacturers are using Gwell's PVB dry process (by roller) and PVB wet process (by water) film equipment. India's first PVB film production line is also made by Gwell.
PVB film width: 3600mm(Max),
PVB film thickness: 0.38-1.52mm,
output: 500-800kg/h,
shrinkage: 2%,
