Polyvinyl Chloride (PVC) iri polymer yeVinyl Chloride Monomer (VCM) Folymerized nePeroxide, manhamba azolymundu polymerization maitiro pasi pechiedza uye kupisa. Vinyl chloride homo polymer uye vinyl chloride co polymer inonzi vinyl chloride resin.
PVC yakashanda kuve yakakura kwazvo-chinangwa mapurasitiki munyika uye yakashandiswa zvakanyanya. Inoshandiswa zvakanyanya muzvivakwa zvekuvaka, zvigadzirwa zveindasitire, zvido zvezuva nezuva, zvidhori zveganda, mapepa, mapepa ekutakura, mabhodhoro, mafuro, zvisimbiso zvekuisa, zviumbwa uye zvichingodaro.
PVC ndeye Amorphous chimiro che chena poda, ine yakaderera crangel degree. Yayo girazi transition tembiricha ndeye 77 ~ 90 ℃, uye inotanga kuora pa170 ℃. Zvichakadaro zvine simba kugadzikana kwechiedza uye kupisa: Zvichaburitsa hydrogen chloride
Iyo kambani inogona kupa pazasi pePVC inopupuma inowedzera:
| Kuiswa | Chigadzirwa | CAS | Type Type | Application |
| Antioxidant | Yihoo an245dw | 36443-68-2 35% 7732-18-5 65% | Sonox 2450dw | Inonyanya kushandiswa mune styrene, synthetic rabha, pom hompelyme uye Copolymer, pu, pet, mbs, uye pvc. |
| Yihoo An333 | 77745-66-65 | Jp333e | Phenol-yemahara antioxidant, inoshandiswa seyakawedzera kupisa stabilizer muPVC, kuvandudza ruvara uye kujeka kwePVC zvigadzirwa. Inogona zvakare kushandiswa muRabha uye Pu zvekushandisa kuti uvandudze kukanganisika kwezvigadzirwa. | |
| Yihoo hp136 | 181314-48-7 | Inogona kupa anoshongedza hydrogen kune rezenerate yakavharirwa phenolik antioxidant uye kuderedza iyo yakawedzerwa chiyero cheiyo mbiri. Yakakodzera kwazvo tembiricha yekuedza |
Kupa Polymer anowedzera pakunyatso shandura, kambani yakawedzera yechigadzirwa yekuvharirwa pazasi: PCU Elasmer emahara ekupedza Agentitives, coating extitives, cosmetsics yekuwedzera, api Zvigadzirwa zvemakemikari zvakaita seEhite etc ..
Unogamuchirwa kuti ubate isu kubvunza!
