Poly Vinyl Carbide

Calcium carbide cac2 calcium carbide is a colorless and odorless solid.

Poly vinyl carbide. Polyvinyl alcohol fiber is a kind of fiber made from pva polyvinyl alcohol including water soluble pva fiber high strength modulus pva fiber calcium carbide molecular formula. Calcium carbide also known as calcium acetylide is a chemical compound with the chemical formula of ca c 2 its main use industrially is in the production of acetylene and calcium cyanamide. In spite of pva easily forming borate ester pvbo 6 7 the synthesis of crystalline boron carbide powder from pvbo under milder conditions than those used in conventional methods has not been reported. Pvc polyvinyl chloride a synthetic resin made from the polymerization of vinyl chloride.

Pvc resin is the most widely raw material used in plastic production. The pure material is colorless however pieces of technical grade calcium carbide are grey or brown and consist of about 80 85 of cac 2 the rest is cao calcium oxide ca 3 p 2 calcium phosphide. The process is also very energy intensive with much waste generated. Coal is the main starting material for the calcium carbide process.

In this work high purity boron carbide with nanosized particles was produced from poly vinyl alcohol and boric acid using a solid state reaction pyrolysis process srpp. Calcium carbide is the chemical name of cac2. It has good chemical stability corrosion resistance and water resistance. The acetylene so generated is then converted to vcm which usually involves the use of a mercury based catalyst.

Carbide based polyvinyl chloride resin pvc resin sg5 k67 1. It can be dissolved in acetone hydrochloric ether ester and some alcohol.

64 10 according to 2001 international relative atomic mass. It can offer good solubility good.
