PVC sealing strips tau dhau los ua cov nyiam ntawm cov yas steel qhov rooj thiab qhov rais sealing strips vim lawv tsis tawg thiab yooj yim rau vuam.Tab sis tsuas yog 2-3 xyoos, qhov teeb meem tshwm sim.Kev sib cais ntawm PVC plasticizers, ib qho teeb meem kev lag luam thoob ntiaj teb nyuaj, tau pom meej meej hauv PVC sealing strips.
Vim yog kev sib cais ntawm cov yas yas, qhov profile yog polluted los ntawm cov roj hmab sawb, qhov ntev yog luv luv, qhov tawg yog luv luv, thiab cov teeb meem ntawm kev sib khi tsis zoo muaj ntau.Txawm li cas los xij, Suav-style me me rhiav ua, Suav-style txo tus nqi, thiab Suav-style kev sib tw nqi qis los ntawm lub qhov rooj thiab qhov rais sealing sawb manufacturers tau coj mus rau kev siv cov yas yas tsis zoo thiab rov siv dua PVC, uas tau ua rau cov teeb meem ntawm tag nrho. sealing sawb kev lag luam.Qhov kawg ntawm PVC sealing sawb yog pib tshwm.
EPDM EPDM sealing strips Thaum ntxov 2000, lub teb chaws tau tshaj tawm tsab cai pej xeem txwv tsis pub siv polyvinyl chloride PVC sealing strips, thiab txhawb kev siv EPDM EPDM sealing strips thiab MVQ silicone roj hmab sealing strips.EPDM sealing sawb, qib high-qib sealing sawb siv hauv tsheb thiab tsheb ciav hlau, thaum kawg tau txais los ntawm kev tsim kho kev lag luam.
Qhov tseeb, nws tau dav siv nyob rau hauv lub qhov rooj thiab qhov rais kev lag luam tom qab 2002. Thaum lub sij hawm ntawd, lub qhov rooj thiab qhov rais maj mam nkag mus rau lub era ntawm tawg choj aluminium alloys.EPDM tau dhau los ua qhov sib txawv nrog cov qib siab sealing strips vim nws lub cev zoo tshaj plaws thiab kev laus ua haujlwm zoo.Xyoo 2011, cuam tshuam los ntawm cov roj thoob ntiaj teb thiab lwm yam, tus nqi ntawm ethylene propylene tau nce siab, thiab lub caij ntuj no ntawm EPDM sealing strips tuaj, yog li Suav kev txawj ntse tuaj, reclaimed roj hmab pib siv ntau, thiab tag nrho cov sealing sawb lag luam nyob rau hauv. kev kub ntxhov.Cov ntsaws ruaj ruaj zoo yog qhov nyuaj los ntawm.Qhov rooj thiab qhov rais sealing strip manufacturers@门Window 气气调板厂家 Ib lub nroog nyob hauv Suav teb yog lub hauv paus ntawm kev sib khi hauv tsev, thiab li ntawm 70% ntawm Tuam Tshoj EPDM lub tsev sealing strips tuaj ntawm lub nroog no.Muaj ib tus thawj coj hauv tib txoj haujlwm hauv lub nroog no, thiab 70% ntawm lub teb chaws ethylene-propylene sealing strips los ntawm peb.
Silicone roj hmab sealing sawb tsis yog cov khoom siv tshiab kawg rau sealing strips, tab sis nws tsis yog.Silicone roj hmab muaj keeb kwm ntawm kaum xyoo hauv Suav teb.Qhov rooj thiab qhov rais sealing sawb manufacturers yog qhov tseeb ntawm cov roj hmab nyiam nyob rau hauv ob peb xyoos dhau los, thiab lawv yog cov muag heev.Nyob rau hauv xyoo tas los no, tus nqi tau maj mam txo qis, thiab lawv tau maj mam thov rau lub tsev foob.
Piv nrog ethylene-propylene roj hmab, qhov zoo ntawm silicone roj hmab rau sealing yog tias nws muaj qhov zoo dua shrinkage thiab deformation kev ua tau zoo dua li ethylene-propylene roj hmab, yog li cov sealing kev ua tau zoo dua, thiab los ntawm lub hauv paus ntsiab lus ntawm lub sij hawm kub sib npaug, silicone roj hmab tuaj yeem tiv taus. kub txog li 300 ° C, thiab resistant rau ethylene-propylene roj hmab.Cov roj hmab yog qhov zoo tshaj plaws ntawm 180 ° C.Nyob rau hauv tib qhov kub thiab txias, lub neej ntawm silicone roj hmab yog ob zaug ntawm ethylene propylene roj hmab, thiab lub neej kev pab cuam ntev dua.Thiab nws muaj qhov zoo ntawm lub cev tsis muaj zog, tsis muaj tshuaj lom, tsis muaj kuab lom, silicone roj hmab kuj muaj cov cua sov ua haujlwm zoo, txias tsis kam, dielectric zog, ozone kuj thiab atmospheric aging kuj thiab lwm yam dej num, kev ua haujlwm zoo ntawm silicone roj hmab yog siv dav kub, tuaj yeem siv lub qhov rooj thiab qhov rais sealing strip chaw tsim khoom rau lub sijhawm ntev ntawm -60 ° C (los yog qis dua) txog + 250 ° C (los yog kub dua).Yog li silicone roj hmab yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov ntsaws ruaj ruaj nyob rau niaj hnub no.
