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.

Poly vinyl carbide.

Pvc is used in an enormous range of domestic and industrial products from raincoats and shower curtains to window frames and indoor plumbing. 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. It can offer good solubility good. The process is also very energy intensive with much waste generated.

The acetylene so generated is then converted to vcm which usually involves the use of a mercury based catalyst. 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. Pvc resin is the most widely raw material used in plastic production. Learn more about pvc in this article.

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. It can be dissolved in acetone hydrochloric ether ester and some alcohol. Coal is the main starting material for the calcium carbide process. Carbide based polyvinyl chloride resin pvc resin sg5 k67 1.

Calcium carbide cac2 calcium carbide is a colorless and odorless solid. Calcium carbide is the chemical name of cac2. 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. 64 10 according to 2001 international relative atomic mass.

Polyvinyl borate pvbo which is a borate ester of pva has been expected as a promising precursor. For an in depth knowledge on the uses physical and chemical properties structure of calcium carbide cac2 visit byju s.
