Ikiranga 1: PVC Rigid nimwe mubikoresho bya plastiki bikoreshwa cyane.Ibikoresho bya PVC ni ibintu bitari kristu.

Ikiranga 2: Stabilisateur, lubricants, ibikoresho bifasha gutunganya, pigment, imiti igabanya ubukana nibindi byongeweho akenshi byongerwa mubikoresho bya PVC mugukoresha nyabyo.

Ikiranga 3: Ibikoresho bya PVC bifite umuriro, imbaraga nyinshi, guhangana nikirere hamwe na geometrike nziza.

Ikiranga 4: PVC irwanya imbaraga za okiside, igabanya imiti na acide ikomeye.Nubwo bimeze bityo ariko, irashobora kwangirika na aside irike nka acide sulfurike yibanze hamwe na acide nitricike yibanze kandi ntibikwiriye guhura na hydrocarbone ya aromatic na hydrocarbone ya chlorine.

Ikiranga 5: Ubushyuhe bwa PVC mugihe cyo gutunganya nikintu cyingenzi cyane.Niba iyi parameter idakwiye, bizatera ikibazo cyo kubora.

Ikiranga 6: Ibiranga imigendekere ya PVC birakennye cyane, kandi inzira yayo iragufi.By'umwihariko uburemere buke bwa molekuline ibikoresho bya PVC biragoye cyane kubitunganya (ubu bwoko bwibikoresho bukenera kongeramo amavuta kugirango tunonosore imiterere), bityo ibikoresho bya PVC bifite uburemere buke bwa molekile.

Ikiranga 7: Igabanuka rya PVC riri hasi cyane, muri rusange 0.2 ~ 0,6%.

Choride ya Polyvinyl, mu magambo ahinnye yitwa PVC (Polyvinyl chloride) mu Cyongereza, ni vinyl chloride monomer (VCM) muri peroxide, ibice bya azo n'abandi batangiza;cyangwa munsi yumucyo nubushyuhe ukurikije uburyo bwa radical polymerisation yubusa yubusa Polymers yakozwe na polymerisation.Vinyl chloride homopolymer na vinyl chloride copolymer hamwe hamwe bita vinyl chloride resin.

PVC ni ifu yera ifite imiterere ya amorphous.Urwego rwishami ni ruto, ugereranije ubucucike bugera kuri 1.4, ubushyuhe bwikirahure ni 77 ~ 90 and, kandi butangira kubora nka 170 ℃.Guhagarara kumucyo nubushyuhe birakennye, hejuru ya 100 ℃ cyangwa nyuma yigihe kinini.Imirasire y'izuba izabora kugirango ikore hydrogène chloride, izakomeza gukora autocatalyse yangirika, itera ibara, kandi imiterere yumubiri nubukanishi nayo izagabanuka vuba.Mubikorwa bifatika, stabilisateur igomba kongerwaho kugirango itezimbere ubushyuhe numucyo.

Uburemere bwa molekile ya PVC yakozwe ninganda mubusanzwe iri hagati ya 50.000 na 110.000, hamwe na polydispersity nini, kandi uburemere bwa molekile bwiyongera hamwe nubushyuhe bwa polymerisation;ntigifite aho gishonga gihamye, itangira koroshya kuri 80-85 and, kandi ihinduka viscoelastic kuri 130 ℃, 160 ～ 180 ℃ itangira guhinduka muburyo bwamazi meza;ifite imiterere yubukanishi, imbaraga zingana zingana na 60MPa, imbaraga zingaruka ni 5 ～ 10kJ / m2, kandi ifite imiterere myiza ya dielectric.

PVC yahoze ari umusaruro munini ku isi wa plastiki-rusange, kandi irakoreshwa cyane.Ikoreshwa cyane mubikoresho byubaka, ibicuruzwa byinganda, ibikenerwa bya buri munsi, uruhu rwo hasi, amabati hasi, uruhu rwubukorikori, imiyoboro, insinga ninsinga, firime zipakira, amacupa, ibikoresho bifuro, ibikoresho bifunga kashe, fibre, nibindi.

Uruganda rwacu rukoresha ibyizaibumbaibikoresho, nka 718, 718H, nibindi, ibikoresho byiza byububiko, kuramba, nibicuruzwa bikoreshwa mubikoresho bitandukanye bya pulasitike birashobora kubyara ibicuruzwa byiza bya plastiki nziza;
