Oge mbụ a chọpụtara PVC bụ na mberede na 1872 site n'aka onye German chemist, Eugen Baumann.A haziri ya dị ka flask nke vinyl chloride hapụrụ ìhè anyanwụ ebe ọ bụ polymerized.
N'ọgwụgwụ 1800s, otu ndị ọchụnta ego German kpebiri itinye ego na imepụta nnukwu acetylene, nke ejiri dị ka mmanụ ọkụ na oriọna.N'otu aka ahụ, ngwọta eletrik na-arụ ọrụ nke ọma na n'oge na-adịghị anya gafere ahịa ahụ.Na nke a acetylene dị n'ụba yana ọnụ ala.
Na 1912, otu onye Germany bụ́ ọkà n’ihe banyere kemịkal, Fritz Klatte, nwalere ihe ahụ ma jiri hydrochloric acid (HCl) meghachi omume na ya.Mmeghachi omume a ga-emepụta vinyl chloride na enweghị ebumnuche doro anya ọ hapụrụ ya na shelf.Na vinyl chloride polymerized ka oge na-aga, Klatte nwere ụlọ ọrụ ọ na-arụ ọrụ, Greisheim Electron, iji patent ya.Ha ahụghị uru ọ bụla maka ya na patent ahụ kubie ume na 1925.
N'onwe ya ọzọ chemist na America, Waldo Semon na-arụ ọrụ na BF Goodrich, na-achọpụta PVC.Ọ hụrụ na ọ nwere ike ịbụ ihe zuru oke maka ákwà mgbochi ịsa ahụ na ha tinyere akwụkwọ ikike.Otu n'ime ihe ndị bụ isi bụ mkpuchi mmiri nke mere ka ọtụtụ ihe eji eme ihe na PVC na-eto ngwa ngwa na òkè ahịa.
Kedu ihe bụ PVC granule na ebe a na-eji ya?
PVC bụ akụrụngwa na-enweghị ike ịhazi ya naanị ma e jiri ya tụnyere ihe ndị ọzọ.Ogige granules PVC na-adabere na nchikota nke polymer na ihe mgbakwunye na-enye usoro dị mkpa maka njedebe.
Mgbakọ na ịdekọ ntinye ntinye dabere na akụkụ otu narị nke resin PVC (phr).A na-emepụta ogige ahụ site na ijikọta ihe ndị dị na ya nke ọma, bụ nke a na-emesị gbanwee n'ime ihe gelled n'okpuru mmetụta nke okpomọkụ (na ịkwa akwa).
Enwere ike ịmepụta ogige PVC, iji plasticizers, n'ime ihe ndị na-agbanwe agbanwe, nke a na-akpọkarị P-PVC.A na-ejikarị ụdị PVC dị nro ma ọ bụ na-agbanwe agbanwe na akpụkpọ ụkwụ, ụlọ ọrụ USB, ala ala, eriri, ihe egwuregwu ụmụaka na ịme uwe.
Ngwakọta na-enweghị plasticizer maka ngwa siri ike ka ahapụtara U-PVC.A na-ejikarị PVC siri ike mee ihe maka ọkpọkọ, profaịlụ windo, mkpuchi mgbidi, wdg.
Ogige PVC dị mfe ịhazi site na ịkpụzi injection, extrusion, ịkpụzi ihe na eserese miri emi.INPVC arụpụtala ogige PVC na-agbanwe agbanwe nke nwere oke ịgba ọsọ, dị mma maka ịkpụzi injection, yana akara viscous nke ukwuu maka extrusion.
