High Purity Methane Gas Description
Uses of High Purity Methane Gas: Standard gas, calibration gas, solar cells, amorphous silicon films, raw material for the production of ethylene, hydrogen, synthetic ammonia, carbon black, methyl compounds, carbon disulfide, hydrogen cyanide, etc.
Physicochemical Properties of High Purity Methane Gas: Colorless, odorless, flammable gas. Slightly soluble in water, soluble in ethanol, ether, benzene, toluene, etc. Relative vapor density (air=1): 0.6, saturated vapor pressure (kPa): 53.32 (-168.8°C).
Precautions for Methane Gas: Operate in a closed system with overall ventilation. Operators must receive specialized training and strictly adhere to operating procedures. It is recommended that operators wear anti-static work clothes. Keep away from fire and heat sources; smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas leakage into the workplace air. Avoid contact with oxidizing agents. During transportation, cylinders and containers must be grounded and bonded to prevent static electricity buildup. Handle with care during搬運 to avoid damage to cylinders and attachments. Equip with appropriate types and quantities of fire-fighting equipment and leakage emergency處理 equipment. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Warehouse temperature should not exceed 30°C. Store separately from oxidizing agents; avoid mixed storage. Use explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that may generate sparks. The storage area should be equipped with leakage emergency處理 equipment.
