Polyvinyl chloride (PVC)rọba bụ ihe mejupụtara ihe mejupụtara site na ịgwakọta resin PVC na mgbakwunye dị iche iche. Ọ na-egosiputa ihe eji arụ ọrụ nke ọma, nguzogide corrosion kemịkalụ, njirimara na-ekpochapụ onwe ya, nguzogide ihu igwe dị mma, ihe mkpuchi ọkụ eletrik dị elu, ịdị mfe nke nhazi, na ọnụ ala dị ala, na-eme ka ọ bụrụ ihe dị mma maka waya na mkpuchi eriri na mkpuchi mkpuchi.
Resin PVC bụ polymer thermoplastic linear nke emere site na polymerization nke vinyl chloride monomers. Nhazi molekụla ya nwere atụmatụ:
(1) Dị ka polymer thermoplastic, ọ na-egosipụta ezigbo plasticity na mgbanwe.
(2) Ọnụnọ nke C-Cl polar agbụ na-enye resin siri ike polarity, na-akpata dịtụ elu dielectric mgbe nile (ε) na dissipation ihe (tanδ), mgbe inye elu dielectric ike na ala frequencies. Njikọ pola ndị a na-enyekwa aka na ike intermolecular siri ike na ike ọrụ dị elu.

Otú ọ dị, atom chlorine ndị a na-akpaghasị ihe owuwu kristal, na-eduga na nguzogide okpomọkụ dị ntakịrị na nguzogide oyi na-adịghị mma, nke enwere ike imeziwanye site na mgbakwunye kwesịrị ekwesị.
2.Ụdị nke PVC resin
Ụzọ polymerization maka PVC gụnyere: polymerization nkwusioru, emulsion polymerization, nnukwu polymerization, na ngwọta polymerization.
Usoro polymerization nkwusioru bụ nke kachasị ugbu a na mmepụta resin PVC, nke a bụkwa ụdị eji waya na ngwa eriri.
A na-ekewa resins PVC nkwusioru-polymerized n'ụdị nhazi abụọ:
Ụdị resin rụrụ arụ (XS-ụdị): Amara ya site na usoro porous, nnabata plasticizer dị elu, plasta dị mfe, njikwa nhazi dị mma, yana obere gel irighiri ihe, na-eme ka ọ bụrụ nhọrọ kacha mma maka ngwa waya na eriri USB.
Ụdị resin kọmpat (ụdị XJ): A na-ejikarị eme ihe maka ngwaahịa rọba ndị ọzọ.
3.Key Njirimara nke PVC
(1) Ihe mkpuchi eletriki: Dị ka ihe dị elu polar dielectric, resin PVC na-egosi ihe mkpuchi ọkụ eletrik dị mma ma dị ntakịrị ma e jiri ya tụnyere ihe ndị na-abụghị polar dị ka polyethylene (PE) na polypropylene (PP). Nguzogide olu karịrị 10¹⁵ Ω·cm; na 25 Celsius C na 50Hz ugboro, dielectric mgbe niile (ε) sitere na 3.4 ruo 3.6, dị iche iche na mgbanwe okpomọkụ na ugboro ugboro; ihe nkwụsị (tanδ) sitere na 0.006 ruo 0.2. Ike ndakpọ na-anọgide na-adị elu na ọnụ ụlọ okpomọkụ na ike ugboro ugboro, na-adịghị emetụta polarity. Otú ọ dị, n'ihi ọnwụ dielectric ya dịtụ elu, PVC adịghị mma maka ngwa eletrik dị elu na nke dị elu, a na-ejikarị ya eme ihe dị ka ihe mkpuchi maka eriri obere na ọkara voltaji n'okpuru 15kV.
(2) Nkwụsi ike ịka nká: Ọ bụ ezie na usoro ihe omimi ahụ na-egosi nkwụsi ike ịka nká nke ọma n'ihi njikọ chlorine-carbon, PVC na-achọ ịhapụ hydrogen chloride n'oge nhazi n'okpuru nrụgide okpomọkụ na ígwè ọrụ. Oxidation na-eduga ná nbibi ma ọ bụ na-agafe agafe, na-eme ka agbaji agbaji, mgbakasị ahụ, ọdịda dị ukwuu nke ihe ndị na-emepụta ihe, na mmebi nke ọrụ mkpuchi ọkụ eletrik. Ya mere, a ga-agbakwunye ihe nkwụnye kwesịrị ekwesị iji meziwanye nguzogide ịka nká.
(3) Njirimara Thermomechanical: Dị ka polymer amorphous, PVC dị na steeti anụ ahụ atọ na ọnọdụ okpomọkụ dị iche iche: steeti iko, steeti dị elu, na steeti viscous. Na iko mgbanwe okpomọkụ (Tg) gburugburu 80 Celsius C na eruba okpomọkụ banyere 160 ° C, PVC na ya iko steeti na ụlọ okpomọkụ enweghị ike izute waya na USB ngwa chọrọ. Mgbanwe dị mkpa iji nweta ngbanwe dị elu na ụlọ okpomọkụ ka ị na-ejigide okpomọkụ zuru oke na nguzogide oyi. Mgbakwunye nke plasticizers nwere ike ịhazigharị okpomọkụ mgbanwe iko nke ọma.

Dị ka onye na-eduga ndị na-ebubata waya na eriri igwe, ONE WORLD (OW Cable) na-enye ogige PVC dị elu maka mkpuchi mkpuchi na ngwa ịkwa akwa, nke a na-ejikarị na eriri ọkụ, eriri ụlọ, eriri nkwurịta okwu, na wiwi ụgbọ ala. Ihe PVC anyị na-egosipụta ihe mkpuchi ọkụ eletrik dị mma, nkwụsị ọkụ, na nguzogide ihu igwe, na-agbaso ụkpụrụ mba ụwa dị ka UL, RoHS, na ISO 9001. Anyị na-agba mbọ ịnye ngwọta PVC a pụrụ ịdabere na ya na nke dị ọnụ ala ahaziri maka mkpa ndị ahịa anyị.
