Polyvinyl chloride (PVC) ipolymer yevinyl chloride monomer (VCM) yakaiswa polymerized ne peroxide, azo macomputer uye nevamwe vatangi kana neyemahara radical polymerization reaction mashini pasi pekuita kwechiedza uye kupisa. Vinyl chloride homo polymer uye vinyl chloride co polymer inonzi vinyl chloride resin.
PVC yaimbova hombe-yechinangwa epurasitiki pasi rose uye yaishandiswa zvakanyanya. Inoshandiswa zvakanyanya mukuvaka zvinhu, zvigadzirwa zvemaindasitiri, zvinodikanwa zvezuva nezuva, dehwe reganda, zvidhinha zvepasi, dehwe rekugadzira, pombi, waya netambo, kuputira firimu, mabhodhoro, zvinhu zvinopupa furo, zvekuisa chisimbiso, tambo nezvimwewo.
PVC inogadziriswa amorphous chena poda, ine yakaderera branched degree. Tembiricha yaro yekuchinja girazi iri 77 ~ 90 ℃, uye inotanga kuora pa170 ℃. Zvichakadaro ine kudzikama kwakadzika kwechiedza uye kupisa: inoora uye inogadzira hydrogen chloride iri pamusoro pe100 ℃ kana mushure menguva yakareba yekuratidzwa nezuva, uye nekuwedzera otomatiki chinogadzira, chinokonzeresa kuparara uye kuderera mumuviri uye zvemagetsi zvivakwa. , stabilizer kana zvimwe zvinowedzera zvinofanirwa kuwedzerwa kusimudzira kugadzikana kwePVC.
Iyo kambani yaigona kupa pazasi pePVC furo zvinowedzera.
