Vim tias pvc resin muaj lub cev zoo, tshuaj lom neeg, hluav taws xob, nplaim hluav taws ua haujlwm, nyob rau xyoo 1930 thiab 40s, txawv teb chaws tau pib siv PVC mos ua cov khoom siv rwb thaiv tsev rau hlau, kev tsim thiab siv cov khoom siv PVC cable hauv Suav teb 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.
PVC cable khoom yog tsim los ntawm polyvinyl chloride resin, stabilizer, plasticizer, muab tub lim, lubricant, antioxidant, colorant thiab lwm yam.
PVC yas vim nws flammability, roj kuj, corona tsis kam, tshuaj corrosion kuj thiab zoo dej kuj, yog li nws kuj yog lug siv los ua ib tug tiv thaiv cov ntaub ntawv thiab cables.Los ntawm kev ntxiv cov khoom siv tshwj xeeb lossis kev hloov kho, cov khoom siv hluav taws xob kub (105 ℃), txias resistant, roj resistant, nplaim resistant, ntxiv-mos thiab tsis muaj tshuaj lom PVC cable cov ntaub ntawv tuaj yeem tsim raws li qhov xav tau ntawm cov khoom tshwj xeeb thiab cov khoom siv cable.
Los ntawm kev ntxiv cov khoom siv tshwj xeeb lossis kev hloov kho, cov khoom siv hluav taws xob kub (105 ℃), txias resistant, roj resistant, nplaim resistant, ntxiv-mos thiab tsis muaj tshuaj lom PVC cable cov ntaub ntawv tuaj yeem tsim raws li qhov xav tau ntawm cov khoom tshwj xeeb thiab cov khoom siv cable.
Polyvinyl chloride (PVC) yas yog cov khoom siv ntau yam yas, raws li kev siv ntau yam, los ntawm kev hloov ntau yam thiab ntau npaum li cas ntawm tus neeg sawv cev complex, yuav ua tau ntau yam ntawm PVC yas rau hlau thiab cable.Polyvinyl chloride (PVC) cable yas raws li nws siv nyob rau hauv cov hlau thiab cable, yuav muab faib mus rau hauv rwb thaiv tsev theem cable cov ntaub ntawv thiab tiv thaiv qib cable khoom.Kev tiv thaiv qib yuav tsum tau ua kom sov zoo, thiab qib rwb thaiv tsev yuav tsum muaj kev rwb thaiv tsev zoo.
Siv kev faib tawm
PVC cable cov ntaub ntawv tuaj yeem muab faib ua:
PVC insulated cable khoom
PVC sheathed cable khoom
Nplaim retardant PVC insulated cable khoom
Nplaim retardant PVC sheathed cable khoom
PVC elastomer cable khoom
PVC sab nraum zoov overhead insulated cable
