Chemistry-Polyvinylchloride and Cellulose Acetate: Production of Polyvinylchloride

http://pvc-and-ca.blogspot.com/2007/04/production-of-polyvinylchloride.html

Chemistry-Polyvinylchloride and Cellulose Acetate. Polyvinyl chloride (PVC) is a thermoplastic and is produced by polymerization. Vinyl chloride. . It is produced in several steps. Vinyl chloride is manufactured industrially from ethylene and chlorine. In the presence of iron(III) chloride as a catalyst, the compounds react to produce ethylene dichloride. CH2=CH2 Cl2 → ClCH2CH2Cl. The vinyl chloride is then isolated. The bonding of two or more monomers to form a polymer. Subscribe to: Post Comments (Atom).

Chemistry-Polyvinylchloride and Cellulose Acetate: Production of Cellulose Acetate

http://pvc-and-ca.blogspot.com/2007/04/production-of-cellulose-acetate.html

Chemistry-Polyvinylchloride and Cellulose Acetate. Production of Cellulose Acetate. Made from cotton and wood. Produced from processing pulp in three main stages; activation,. The pulp is processed using acetic anhydride to form cellulose acetate flake from which products are made. Chemical and word equations of the production process:. 1 [C6H7O2(OH)3]n 3n(CH3CO)2O - - - [C6H7O2(OOCCH3)3]n 3nCH3COOH. Cellulose Acetic Anhydride(with the catalyst:H2SO4)- - - Cellulose Triacetate Acetic Acid.

http://pvc-and-ca.blogspot.com/2007/04/properties-of-polyvinylchloride.html

Chemistry-Polyvinylchloride and Cellulose Acetate. Properties of Polyvinylchloride are as follows:. Heavy, stiff, ductile and medium strong amorphous (transparent) material. Can be a flexible or rigid material that is chemically nonreactive. Easily machined, heat formed, welded, and even solvent cemented. Can also be machined using standard metal working tools and finished to close tolerances and finishes without great difficulty. Accepts paint and performs well under most silk screening processes.

Chemistry-Polyvinylchloride and Cellulose Acetate: Manufacture of Polyvinylchloride Products

http://pvc-and-ca.blogspot.com/2007/04/manufacture-of-polyvinylchloride.html

Chemistry-Polyvinylchloride and Cellulose Acetate. Manufacture of Polyvinylchloride Products. When moulding PVC into products for usage, a few processes are carried out. For plastic moulding, molten plastic is injected at high pressure into a mold, which is the inverse of the product's shape. An example of a product of polyvinylchloride: a children's doll. Introduction to manufacturing process of a children's doll:. Is sometimes used to make the torso if cost is an issue since it is a faster, more econom...
