Qhov zoo ntawm PVC profiles
May 23, 2022
PVC, lub npe tag nrho yog Polyvinylchlorid, lub ntsiab tseem ceeb yog polyvinyl chloride, thiab lwm yam khoom siv ntxiv los txhim kho nws cov cua sov, toughness, ductility, thiab lwm yam. chloride, thiab cov txheej hauv qab yog cov nplaum nplaum rov qab. Nws yog ib qho zoo-hlub, nrov thiab dav siv cov khoom siv hluavtaws hauv ntiaj teb niaj hnub no. Nws txoj kev siv thoob ntiaj teb yog qhov thib ob siab tshaj plaws ntawm tag nrho cov khoom siv hluavtaws. Raws li kev txheeb cais, xyoo 1995 ib leeg, kev tsim cov PVC hauv Tebchaws Europe yog kwv yees li 5 lab tons, thaum nws noj yog 5.3 lab tons. Nyob rau hauv lub teb chaws Yelemees, PVC ntau lawm thiab noj nruab nrab 1.4 lab tons. PVC tau raug tsim thiab siv thoob ntiaj teb ntawm kev loj hlob ntawm 4 feem pua. Nyob rau hauv xyoo tas los no, kev loj hlob ntawm PVC nyob rau sab hnub tuaj Asia yog qhov tseem ceeb tshwj xeeb, ua tsaug rau qhov kev xav tau ceev rau kev tsim kho vaj tse hauv cov tebchaws Esxias sab hnub tuaj. Ntawm cov ntaub ntawv uas tuaj yeem tsim cov duab peb sab, PVC yog dav siv. PVC yog cov khoom tsim nyog. Ntxiv rau cov ntaub ntawv yas PVC, muaj ntau yam khoom siv yas xws li PC profiles, abs profiles, thiab yas extruded lampshades.
PVC yog polyvinyl chloride. Ntawm tag nrho cov yas, tus nqi ntawm PVC resin hmoov yog muaj. Qhov zoo dua yog tias nws pheej yig thiab muaj lub zog zoo thiab toughness. Qhov tsis zoo yog tias PVC resin hmoov tsis tuaj yeem siv ncaj qha, tab sis yuav tsum tau ntxiv nrog cov khoom siv ntxiv thiab cov stabilizers. Cov khoom siv pabcuam nkag mus rau hauv, thiab tom qab ntawd cov khoom tuaj yeem tsim tau, thiab muaj cov kev cai tshwj xeeb rau extrusion screws thiab chim. Vim yog kev sib raug zoo ntawm plasticizing, cov khoom siv yog tsom.
