Product description
  Product Name: silane Sulfane
  Molecular formula: SiH
  Silane is a colorless gas that reacts with air and causes choking. The gas, usually in contact with the air, causes combustion and emits dense white amorphous silica fume. Its primary danger to health is that its spontaneous combustion can cause severe heat burns, if severe or even fatal. If the flame or high temperature acts on a part of the silane cylinder, the cylinder explodes before the safety valve is started. If the pressure is too high or too fast when releasing silane, it will cause a delayed explosion. Leaks of silane, if not spontaneous, can be very dangerous, do not approach. Emergency personnel must have personal protective equipment and fire protection adapted to the circumstances. Do not attempt to extinguish the fire before cutting off the gas supply.
  Product description:
  Silane gas is indispensable in the production of solar cells because it is the most effective way to attach molecules to the surface of the battery. At temperatures higher than 400 DEG C, silane gas is decomposed into gaseous silicon and hydrogen gas. When the hydrogen burns, the rest is pure silicon. In addition, silane gas can be said everywhere. In addition to the photovoltaic industry, there are many manufacturing plants need to use silane gas, such as flat panel display, semiconductor, and even coated glass manufacturing plant.
  Silane precautions:
  Use silane to ventilate the workplace and keep room air dry. Silane device must be strictly sealed, and avoid air and water contact, therefore, gas device in use before using inert gas to replace the air inside after vacuum pumping, such repeated replacement and vacuum must be completely removed in the system of air and water. The device also uses inert gas to replace the silane in the cleaning system. Helium leak detector can be used to detect leaks. When a small amount of silane is leaked, it is also known from the folding of the silica powder. Keep the cylinders in a cool, dry, well ventilated place. Keep away from heat and chlorine, bromine, and other oxidants. The workplace should be equipped with adequate protection and emergency supplies. The silane itself is non corrosive, can use carbon steel, stainless steel, copper, brass, Monel, nickel based alloy. Can also be used PTFE, poly three fluorine vinyl chloride polymer, nylon, three fluorine vinyl chloride resin, polyethylene, polyester, quartz glass. No lead, rubber, fat, grease, glass. All flammable organic polymer materials should be avoided. When the silane leaks in large quantities. The fire is going on, so you can't use a fire extinguisher to put out the fire. But the fire can be controlled so that the fire does not spread around. The heat of radiation is not too high during combustion, so the valve should be closed as much as possible to stop the flow of gas. Dust or graphite powder can be used to stall. The exhaust gas can be absorbed by water or alkali, or it can be burned in SiO2 in a special burner and then captured with a special filter. Store in a cool, airy warehouse. Keep away from fire and heat. The temperature should not exceed 30 DEG C. Should be stored with easy (combustible), oxidizer, separately, must not be mixed storage. The storage area shall be equipped with emergency disposal equipment for leakage. Closed operation, partial air exhaust. Operators must undergo special training and strictly follow the operating procedures. The operator is advised to wear a filter mask (half mask). Keep away from flammable and combustible materials. Prevent gas from leaking into the air in the workplace. Avoid contact with oxidants. Remove light and light when handling and prevent damage to cylinder and fittings. Equipped with emergency disposal equipment for leakage.
