Chinhu chekutanga: PVC yakasimba ndeimwe yezvinhu zvepurasitiki zvinoshandiswa zvakanyanya. Zvinhu zvePVC hazviratidzike semakristaro.

Chinhu chechipiri: Zvinosimbisa, mafuta ekuzora, zvinhu zvinobatsira pakugadzirisa, pigments, zvinhu zvinodzivirira kukanganiswa nezvimwe zvinowedzera zvinowanzoiswa muzvinhu zvePVC pazvinenge zvichishandiswa.

Chinhu chechitatu: Zvinhu zvePVC hazvibati moto, zvine simba guru, hazvichinji mamiriro ekunze uye hazvina kugadzikana zvakanyanya.

Chinhu chechina: PVC inodzivirira zvakasimba ma oxidants, reduction agents uye strong acids. Zvisinei, inogona kukuvadzwa ne concentrated oxidizing acids dzakadai se concentrated sulfuric acid ne concentrated nitric acid uye haina kukodzera kusangana ne aromatic hydrocarbons uye chlorinated hydrocarbons.

Chinhu 5: Kupisa kwekunyunguduka kwePVC panguva yekugadzirisa chinhu chakakosha zvikuru. Kana parameter iyi isina kunaka, inokonzera dambudziko rekuora kwezvinhu.

Chinhu 6: Hunhu hwePVC hwekuyerera hushoma, uye huwandu hwayo hwekushanda hushoma. Kunyanya zvinhu zvePVC zvine huremu hwakawanda zvinonetsa kugadzirisa (rudzi urwu rwezvinhu runowanzo fanirwa kuwedzera mafuta kuti ruvandudze hunhu hwekufamba), saka zvinhu zvePVC zvine huremu hudiki ndizvo zvinowanzo shandiswa.

Chinhu 7: Kuderera kwePVC kwakaderera, kazhinji 0.2 ~ 0.6%.

Polyvinyl chloride, yakapfupikiswa sePVC (Polyvinyl chloride) muchiRungu, ivinyl chloride monomer (VCM) muperoxides, azo compounds nezvimwe zvinotanga; kana pasi pesimba rechiedza nekupisa zvichienderana ne free radical polymerization reaction mechanism. Mapolymers anoumbwa ne polymerization. Vinyl chloride homopolymer uye vinyl chloride copolymer pamwe chete zvinonzi vinyl chloride resin.

PVC ihupfu huchena husina chimiro chakafanana. Hukuru hwemapazi hudiki, huwandu hwezvinhu hunenge 1.4, tembiricha yekuchinja kwegirazi ndeye 77~90℃, uye inotanga kuora pa170℃. Kugadzikana kwechiedza nekupisa hakuna kunaka, pamusoro pe100℃ kana mushure menguva yakareba. Kusviba nezuva kunoora kuti kubudise hydrogen chloride, iyo ichaita kuti kuora kuwedzere otomatiki, zvichikonzera kuchinja kweruvara, uye hunhu hwemuviri nehwemakanika huchadzikirawo nekukurumidza. Mukushandiswa kwazvino, zvinosimbisa zvinofanirwa kuwedzerwa kuti zvivandudze kugadzikana kwekupisa nechiedza.

Huremu hwemamorekuru ePVC inogadzirwa mumaindasitiri hunowanzova pakati pe50,000 ne110,000, ine polydispersity yakakura, uye huremu hwemamorekuru hunowedzera nekudzikira kwetembiricha yepolymerization; haina nzvimbo yekunyunguduka yakatarwa, inotanga kunyorova pa80-85℃, uye inova viscoelastic pa130℃, 160 ~ 180℃ inotanga kushanduka kuita viscous fluid state; ine hunhu hwakanaka hwemakanika, simba rekudhonza rinosvika 60MPa, simba rekubaya i5 ~ 10kJ/m2, uye ine hunhu hwakanaka hwe dielectric.

PVC yaimbova chigadzirwa chikuru pasi rose chepurasitiki dzinoshandiswa zvakanyanya, uye inoshandiswa zvakanyanya. Inoshandiswa zvakanyanya muzvinhu zvekuvaka, zvigadzirwa zvemaindasitiri, zvinodiwa zvezuva nezuva, dehwe repasi, mataira epasi, dehwe rekugadzira, mapaipi, waya netambo, mafirimu ekurongedza, mabhodhoro, zvinhu zvinofuridzira furo, zvinhu zvekuvhara, fiber, nezvimwewo.

Fekitori yedu inoshandisa zvakanakachakuvhuvhuzvinhu zvakaita se718, 718H, nezvimwewo, zvinhu zvakanaka zvechimurenga, hupenyu hurefu, uye zvigadzirwa zvinoshandiswa mupurasitiki dzakasiyana zvinogona kugadzira zvigadzirwa zvepurasitiki zvemhando yepamusoro
