Polyvinyl chloride (PVC) yog cov polymer ntawm vinyl chloride monomer (VCM) polomerized los yog lwm tus thawj tswj hwm kev sib xyaw ua ke hauv lub teeb thiab kub. Vinyl chloride homo polymer thiab vinyl chloride co polymer yog hu ua vinyl chloride resin.
PVC siv los ua qhov loj tshaj plaws-lub hom phiaj yas hauv ntiaj teb thiab tau siv dav. Nws yog dav siv nyob rau hauv cov khoom lag luam, cov khoom lag luam, khoom siv hauv pem teb, cov xaim ntim hauv pem teb, cov ntaub ntawv ntim, ntim khoom, khaws ntaub ntawv, fibers thiab lwm yam.
PVC yog amorphous qauv ntawm cov hmoov dawb, nrog qis branched degree. Nws cov iav hloov cua kub yog 77 ~ 90 ℃, thiab pib decompose at170 ℃. Lub caij no nws tsis muaj kev ruaj khov ntawm lub teeb thiab cua sov: nws yuav ua rau hydrogen caturalide, uas ua rau muaj kev sib txawv ntawm lub cev, thiab ntxiv rau hauv kev sib txawv ntawm lub cev, thiab ntxiv rau hauv kev sib txawv ntawm lub cev, thiab ntxiv rau hauv kev sib txawv ntawm lub cev, thiab lwm yam ntxiv rau kev sib txawv los txhim kho kev ruaj ntseg ntawm PVC.
Lub tuam txhab tuaj yeem muab rau hauv qab no PVC ua npuas ncauj ntxiv:
| Kev sib faib | Khoom | Cas | Khoom Yam | Daim ntawv thov |
| Tshuaj tua kab mob antioxidant | Yihoo An245DW | 36443-68-2 35% 7732-18-5 65% | Sonox 2450dw | Mas siv nyob rau hauv styrene, hluavtaws roj hmab, pom homopolymer thiab copolymer, pa, tsiaj, mbs, thiab pvc. |
| Yihoo An333 | 77745-66-5 | JP333E | Cov tshuaj phenol-free antioxidant, siv raws li cov tshav kub siv hluav taws xob hauv PVC, txhim kho cov xim thiab pob tshab ntawm PVC cov khoom lag luam. Nws kuj tseem siv tau rau hauv cov roj hmab thiab pu cov khoom siv los txhim kho kom muaj kev tiv thaiv kev tiv thaiv. | |
| Yihoo HP136 | 181314-48-7 | Nws tuaj yeem muab cov hydrogen nquag rau cov kab mob hnyav thaiv phenolic antioxidant thiab txo cov feem sib piv ntawm ob aos. Haum rau kev siv hluav taws xob kub siab, pp, bopp membrane, PC pob tshab rov qab siv, PPR cov khoom siv, TPU, nplaum, thiab lwm yam. |
Txhawm rau muab cov ntawv thov tshwj xeeb ntxiv, lub tuam txhab tau tsim cov khoom sib ntxiv hauv qab no, siv ua npuas ncauj ntxiv, pum polymerization, pu tsev poline, pu ua npuas ncauj ntxiv, pu khoom ua npuas ncauj ntxiv, pu tsev polrification, cov tshuaj txhuam ntxiv, tshuaj pleev ib ce ntxiv, tshuaj pleev ib ce thiab lwm yam tshuaj cov khoom lag luam zoo li Zeolite thiab lwm yam
Koj ib txwm zoo siab tos txais hu rau peb txog cov lus nug!
