Isi ihe nke njikwa usoro maka njikwa ụfụfụ PVC

Onye na-ahụ maka ịfụfụ PVC nwere ike inyere anyị aka iweta ihe ndị dị mma n'oge mmepụta na nhazi nke PVC, na-eme ka mmeghachi omume anyị na-aga n'ihu nke ọma ma mepụta ngwaahịa anyị chọrọ.

E kewara ihe na-akpụzi ụfụfụ rọba nke onye na-ahụ maka ịfụfụ PVC n'ime usoro atọ: nhazi nke isi afụ, mgbasawanye nke isi afụ, na ịkwado ahụ ụfụfụ. Maka mpempe akwụkwọ ụfụfụ nke PVC na ihe mgbakwunye kemịkalụ agbakwunyere, mgbasawanye nke nuclei afụ nwere mmetụta dị mkpa n'ịdị mma nke mpempe akwụkwọ ụfụfụ. PVC bụ nke ụmụ irighiri ihe ndọtị kwụ ọtọ nwere ụdọ molekụla dị mkpụmkpụ yana ike mgbaze dị ala. N'oge usoro nke afụ isi mgbasawanye n'ime egosipụta, gbazee ezughị iji kpuchie egosipụta, na gas na-adịkarị mfe na-ejupụta na jikota n'ime nnukwu egosipụta, ibelata ngwaahịa àgwà nke ụfụfụ Ibé akwụkwọ.

Isi ihe na-eme ka mma nke ndị na-emepụta ụfụfụ PVC dịkwuo mma bụ ime ka ike gbazee nke PVC dịkwuo elu.
