Product description

Parameters

　　Product Name: four fluorinated carbon carbon tetrafluoride

　　Alias: Teflon Tetrafluoromethane

　　Molecular formula: CF4

　　Properties: four carbon fluoride is a non burning, colorless, odorless compressed gas filled in four carbon dioxide cylinders with a saturated vapor pressure of about 2000 psig.

　　Application: four is the amount of carbon fluoride in the microelectronics industry's largest plasma etching gas, can be widely used in silicon, silicon dioxide, silicon nitride, silicon and glass etching phosphorus tungsten thin film materials, surface cleaning in electronic devices, solar cell production, laser technology, gas insulation, refrigeration, leakage inspection agent, the space rocket attitude control, decontamination agent etc. in the production of printed circuit is also widely used. Because of the chemical stability of four carbon fluoride, four carbon fluoride can be used in metal smelting, such as copper, aluminum, stainless steel, carbon steel, Monel etc; also can be used in plastics industry; such as: synthetic rubber, chloroprene rubber, polyurethane.

　　Matters needing attention：

　　Four fluorinated carbon is nonflammable compressed gas. Store in a cool, ventilated room. The temperature in the warehouse shall not exceed 60 degrees centigrade. Keep away from fire and heat. Keep the sun from direct sunlight. Should be stored separately from flammable or combustible materials. Acceptance should pay attention to the name of goods, pay attention to the date of inspection bottles, the first use of advanced warehouse. Handling four carbon dioxide light, light unloading, to prevent damage to the cylinder and accessories. When the leak, should quickly evacuate the leak pollution area, personnel first wind, and isolation, strictly restricting access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and regular work clothes. Cut off the leak as much as possible. Reasonable ventilation and accelerated diffusion. If possible, use immediately. Leak containers should be properly handled, repaired, tested and then used.
