PVC RESIN rau Cable
PVC RESIN rau Cable,
PVC Cable Compound, PVC Cable Raw Khoom, PVC rau Hluav Taws Xob Hlau, PVC cob rau cable rwb thaiv tsev,
PVC vim tias nws muaj lub cev zoo, tshuaj lom neeg, hluav taws xob, nplaim hluav taws ua haujlwm, nyob rau xyoo 1930 thiab 40s, txawv teb chaws pib siv PVC mos ua cov khoom siv rwb thaiv tsev rau hlau, kev txhim kho thiab siv cov khoom siv PVC cable hauv peb lub teb chaws pib xyoo 1950s.Nrog rau kev txhim kho lub peev xwm ntau lawm ntawm PVC cob, plasticizer thiab industrial additives thiab kev nce qib thiab kev siv ntau yam tshiab, kev lag luam cable muaj qhov zoo tshaj plaws leap.
Nyob rau hauv lub xyoo pua 21st, nrog kev txhim kho ntawm tib neeg ib puag ncig kev paub thiab tib neeg kev mloog rau lawv tus kheej kev noj qab haus huv, teeb meem ib puag ncig tau dhau los ua qhov tseem ceeb ntawm tib neeg lub neej.Ntau lub teb chaws, cheeb tsam thiab cov koom haum tau tsim cov qauv nruj thiab cov kev cai txwv tsis pub siv cov tshuaj phem, tshwj xeeb tshaj yog cov cai RolS thiab REACH.Nrhiav cov txheej txheem tshiab thiab cov txheej txheem tshiab, txhim kho kev siv tus nqi ntawm cov peev txheej, hloov mus rau cov cai ntawm kev tiv thaiv ib puag ncig cov cai thiab cov cai, kev tiv thaiv ib puag ncig PVC cable cov ntaub ntawv tau tshwm sim tam sim no, thiab sai dhau los ua ib qho ntawm cov ntsiab lus ntawm cov ntaub ntawv PVC cable tam sim no. .
Kev hloov pauv thiab nthuav dav ntawm kev lag luam xav tau rau cov xaim thiab cable (xws li cable), nrog rau kev tshawb fawb tob txog ntau yam khoom siv tshiab (xws li nplaim hluav taws xob additives, hluav taws xob hluav taws xob hluav taws xob), txhawb kev nce qib thiab kev siv tshiab. technologies, cov ntaub ntawv tshiab thiab cov khoom tshiab ntawm cov ntaub ntawv PVC.Nyob rau hauv ib tug loj npaum li cas ntawm cov khoom siv organic (xws li yas, roj hmab) siv nyob rau hauv kev lag luam cable, tus nqi ntawm PVC cable khoom yog thawj organic khoom nyob rau hauv peb lub teb chaws.
Lub thermoplastic high-molecular polymer ua los ntawm kev ncua polymerization ntawm vinyl chloride monomer.Cov mis mos molecular:- (CH2 - CHCl) n - (N: degree ntawm polymerization, N = 590 ~ 1500).Nws yog cov khoom siv dav dav siv hauv kev tsim khoom yas.Nws muaj kev ruaj ntseg tshuaj zoo, corrosion kuj thiab dej tsis kam.
