PVC tawv yog dab tsi?,
nruj PVC extrusion, uPVC,
Rigid PVC (tseem hu uauPVC) yog qhov thib peb feem ntau tsim cov polymer.Nyob rau hauv cov nqe lus ntawm yas extrusion, PVC yog cov feem ntau extruded rigid yas.Nws yog tus nqi qis, muaj cov khoom siv rov ua dua tshiab thiab muaj ntau yam siv rau sab hauv tsev thiab sab nraum zoov.Qhov no ua raunruj PVC extrusionsa nrov xaiv rau ntau yam kev siv.uPVC stands rau unplasticised PVC thiab cov khoom yog yus muaj los ntawm nws durability thiab lub zog.Nws kuj yog ib qho yas uas hloov tau yooj yim, zoo rau ntau daim ntawv thov
Rigid PVC cov khoom
PVC yog ib qho nyuaj polymer uas tuaj yeem txhim kho ntxiv siv cov kev hloov pauv.Rigid PVC extrusion muaj zog chemical resilience.Qhov no txhais tau hais tias nruj PVC tubing tuaj yeem yooj yim welded, glued thiab fused rau nws tus kheej - zoo tagnrho rau cov pob qij txha hauv cov kav dej.Nws tiv thaiv corrosion ua rau extruded nruj PVC profiles, ntu thiab trims haum rau sab nraum zoov ib puag ncig.PVC kuj tseem muaj cov khoom siv hluav taws xob zoo rau kev siv hluav taws xob tsawg.Ua tsaug rau nws ntau yam txiaj ntsig,nruj PVC extrusions thiab nruj PVC tubing tau siv nrog kev vam meej hauv ob qho tib si sab hauv tsev thiab sab nraum zoov.
Rigid PVC extrusion nyob rau hauv kev siv
Rigid PVC yog dav siv nyob rau hauv kev tsim kho rau cov kav dej thiab khib nyiab, conservatories, gutters, cladding, phab ntsa thiab qhov rooj tiv thaiv thiab qhov rais thav ntawv vim nws zoo heev thermal zog thiab stability.Hauv kev thauj khoom siv uPVC yog siv sab nraud rau lub cev tsheb, caravans thiab nkoj, thiab sab hauv los tsim kom muaj kev zoo nkauj zoo nkauj, vim nws muaj ntau xim thiab ua tiav.Nyob rau hauv cov khw muag khoom lag luam taw tes ntawm kev muag khoom, cov racks cia, daim pib strips thiab daim ntawv tshaj tawm grippers yog tag nrho cov tsim los ntawm extruded rigid PVC.
Nta thermo plasticity, ua insoluble rau hauv dej, roj av thiab cawv, swelled los yog yaj rau hauv ether, ketone, chlorinated aliphatic hydrocarbons, thiab aromatic hydrocarbon, siab tiv thaiv corrosion, thiab zoo dielectric khoom.
Daim ntawv thov
PVC Resin SG-3 Daim Ntawv Thov:
1. PVC profile
Profiles yog thaj chaw ntawm PVC noj nyob rau hauv lub teb chaws, kwv yees li 25% ntawm tag nrho cov PVC noj, feem ntau yog ua rau lub qhov rooj thiab qhov rais thiab lub zog txuag cov ntaub ntawv, thiab lawv daim ntawv thov tseem loj thiab loj hlob.
2. PVC yeeb nkab
PVC kav yog qhov thib ob loj tshaj plaws kev lag luam, kev noj yog 20% ntawm tag nrho cov muaj peev xwm tsim nyob rau hauv Tuam Tshoj, lub PVC yeeb nkab.
3. PVC zaj duab xis
PVC zaj duab xis foob yog 3rd loj kom muaj nuj nqis, nws yog hais txog 10% ntawm tag nrho cov peev xwm ntau lawm.
