PVC qhov rais yog dab tsi?
PVC, los yog polyvinyl chloride, yog cov yas polymer.Nws yog Ameslikas tsim los ntawm German chemist Eugen Baumann nyob rau hauv 1872 thaum nws tso ib lub hwj ntawm vinyl chloride raug tshav ntuj.Nws coj mus txog rau xyoo 1920s rau ib daim ntawv ntawm PVC los tsim uas muaj zog txaus rau kev lag luam.
PVCu qhov rais yog dab tsi?
PVCu qhov rais yog tsim los ntawm PVC uas tau hloov kho nrog cov khoom siv ntxiv los muab nws qee yam khoom, xws li tiv thaiv kev puas tsuaj los ntawm tshav ntuj, dej thiab cua sov.
Ib qho tshuaj ntxiv uas tsis suav nrog hauv cov npe khoom xyaw rau PVCu yog plasticisers.Hauv ntau daim ntawv thov ntawm PVC (xws li flooring) cov no tau ntxiv los ua kom cov khoom hloov tau yooj yim.Tab sis nyob rau hauv lub qhov rais manufacturing tsis muaj plasticizers ntxiv, kom lub qhov rais thav duab nruj thiab muaj zog.PVCu yog qee zaum hu ua RPVC: Rigid PVC.
Nws yog qhov tsis muaj plasticisers uas muab "u" rau hauv PVCu, nws yog unplasticised polyvinyl chloride.
UPVC qhov rais yog dab tsi?
Yooj yim - UPVC tib yam li PVCu, tsuas yog qee tus neeg xaiv muab koj tso rau pem hauv ntej es tsis txhob thaum kawg!
Yuav ua li cas PVCu (los yog UPVC) qhov rais raug tsim
Hloov PVC rau PVC
PVC resin yog tov nrog cov additives uas yuav tsum tau, rhuab los ua ke cov khoom xyaw, ces txias, sieved thiab blended los muab ib tug du, zoo ib yam khoom zaum kawg.Lub resulting PVCu yog qhuav rau hauv hmoov.
Cov hmoov PVCu yog extruded los tsim lub qhov rais thav duab.Qhov no txhais tau hais tias nws yog rhuab mus txog rau thaum nws yog molten, ces yuam los ntawm ib tug tuag, sib sau ua tus xav tau kev pab rau lub qhov rais profile.
Tsim lub qhov rais PVCu
Lub tsib los yog rau meter ntev ntawm extruded PVCu yog ces txiav mus rau qhov loj siv precision machinery.
Cov ntu ntawm tus ncej yog kho los ntawm cua sov cov npoo thiab vuam ua ke.Ntau yam txheej txheem ua raws li, ntxiv glazing, seals thiab fixtures rau lub qhov rais.
Cov txiaj ntsig ntawm PVCu windows
Lub rigidity thiab durability ntawm PVCu sai sai ua nws lub thwj rau ntawm lub qhov rais thiab qhov rooj lag luam nyob rau hauv thaum ntxov 1980s.Cov neeg siv khoom tau lees paub qhov zoo ntawm cov khoom siv ruaj ntseg, tsis tshua muaj txij nkawm.Tsis zoo li lub qhov rais ntoo, PVCu yuav tsis muaj xim, rot lossis warp.Thiab lawv tsis xav tau repainting txhua ob peb xyoos.
PVCu qhov rais muab cov thermal rwb thaiv tsev zoo thiab suab rwb thaiv tsev, txo koj cov nqi cua sov thiab ua kom nrov nrov.
Raws li lub sijhawm tau dhau mus, PVCu qhov rais tau dhau los ua PVC F sophisticated.Muaj ntau hom qauv muaj, ua qauv zoo li qub ntoo lossis hlau qhov rais, tab sis nrog txhua qhov zoo ntawm cov khoom siv niaj hnub no.
