1 The merits of the acetylene gas and the defects of new type of welding gas are completely mixed together on the aspect of theory and practice .

2 Acetone is the solvent which will dissolve the acetylene gas charged into the cylinder.

3 The status of VCM and acetylene gas recovery by pressure swing adsorption in vinyl chloride production units were introduced.

4 Heated with water decomposition of acetylene gas and calcium hydroxide,[] and the evolution of considerable heat.

5 Yedan, oxygen, nitrogen, acetylene gas, acetylene sales; Chemical products, metal Dianliao, plumbing materials, supplies wash sales.

6 The acetylene gas generated by calcium carbide can be applied to weld or cut metal materials.

7 For improving need assembling the casing head, the cutting casing pipe on project, we have designed the device of cutting casing head to change unfavorable factors using acetylene gas to cut case.

8 The utility model relates to a multi-purpose gun for flame cutting of oxygen gas and acetylene gas.

9 About 85% of the enterprises in our country which use fuel gas take use of acetylene gas.

10 Usage:It is the raw material of organic synthesis and calcium Cyanamide. It can produce acetylene gas, and can be used as Deoxidizer for steel making and cut metal.
