Feature 1: Rigid PVC ndeimwe yeanonyanya kushandiswa epurasitiki zvinhu.PVC zvinhu hazvisi-crystalline zvinhu.

Feature 2: Stabilizers, lubricant, anobatsira ekugadzirisa maajenti, pigment, anti-impact agents uye zvimwe zvinowedzera zvinowanzowedzerwa kune PVC zvinhu mukushandiswa chaiko.

Feature 3: PVC zvinhu hazvina-kupisa, simba rakakura, kuramba mamiriro ekunze uye kugadzikana kwejometri yakanakisa.

Feature 4: PVC ine kuramba yakasimba kune oxidants, inoderedza maajenti uye yakasimba asidhi.Nekudaro, inogona kusvibiswa neyakaomeswa oxidizing asidhi yakadai seyakaomeswa sulfuric asidhi uye yakadzika nitric acid uye haina kukodzera kubatwa neanonhuhwirira hydrocarbons uye chlorinated hydrocarbons.

Feature 5: Iyo yekunyunguduka tembiricha yePVC panguva yekugadziriswa yakakosha maitiro parameter.Kana iyi parameter isina kunaka, inokonzera dambudziko rekuparara kwezvinhu.

Feature 6: Kuyerera kwePVC maitiro asina kunaka, uye maitiro ayo akasiyana akatetepa.Kunyanya iyo yakakwira molecular huremu PVC zvinhu zvakanyanya kunetsa kugadzirisa (iyi mhando yezvinhu kazhinji inoda kuwedzera lubricant kuti ivandudze kuyerera maitiro), saka iyo PVC zvinhu zvine huremu hudiki hwemamorekuru inowanzo shandiswa.

Feature 7: The shrinkage rate yePVC yakaderera, kazhinji 0.2 ~ 0.6%.

Polyvinyl chloride, yakapfupikiswa sePVC (Polyvinyl chloride) muChirungu, inonzi vinyl chloride monomer (VCM) mu peroxides, azo compounds nezvimwe zvinotanga;kana pasi pechiito chechiedza uye kupisa zvinoenderana nemahara radical polymerization reaction mechanism Polymers inoumbwa nepolymerization.Vinyl chloride homopolymer uye vinyl chloride copolymer dzinonzi pamwe chete sevinyl chloride resin.

PVC ipfu chena ine amorphous chimiro.Dhigirii rebazi idiki, density yehukama ingangoita 1.4, tembiricha yegirazi i77 ~ 90 ℃, uye inotanga kuora ingangoita 170 ℃.Kugadzikana kuchiedza uye kupisa kwakashata, pamusoro pe100 ℃ kana mushure menguva refu.Kuratidzwa kwezuva kunoora kuburitsa hydrogen chloride, iyo inozowedzera autocatalyze kuparara, zvichikonzera kubuda kwemavara, uye hunhu hwemuviri uye hwemagetsi huchadzikirawo nekukurumidza.Mukushanda kwekushanda, stabilizers inofanira kuwedzerwa kuvandudza kugadzikana kwekupisa uye chiedza.

Huremu hwemamorekuru hwePVC inogadzirwa mumaindasitiri kazhinji huri pakati pe50,000 kusvika 110,000, ine polydispersity yakakura, uye huremu hwemamorekuru hunowedzera nekudzikira kwekupisa kwepolymerization;haina kunyungudika yakagadzika, inotanga kupfava pa80-85℃, uye inova viscoelastic pa130℃, 160～180℃ inotanga kushanduka kuita viscous fluid state;ine yakanaka mechanicha zvivakwa, iyo tensile simba ingangoita 60MPa, simba rekuita i5～10kJ/m2, uye ine yakanakisa dielectric zvivakwa.

PVC yaimbove yakanyanya kugadzirwa pasirese-chinangwa mapurasitiki, uye inoshandiswa zvakanyanya.Inoshandiswa zvakanyanya mukuvaka, zvigadzirwa zvemaindasitiri, zvinodikanwa zvezuva nezuva, dehwe repasi, mataira epasi, dehwe rekugadzira, pombi, waya netambo, kurongedza mafirimu, mabhodhoro, zvinhu zvinopupuma, zvekuisa chisimbiso, fiber, nezvimwe.

Fekitari yedu inoshandisa zvakanakamoldzvinhu, zvakaita se718, 718H, nezvimwewo, zvinhu zvakanaka zvekuumbwa, hupenyu hurefu, uye zvigadzirwa zvinoshandiswa mumhando dzakasiyana dzepurasitiki zvinogona kugadzira zvigadzirwa zvemhando yepamusoro.
