Nrog rau kev txhim kho tas mus li thiab siv cov roj hmab butyl roj hmab tsis muaj dej, ntau yam khoom siv roj hmab butyl tau siv dav hauv txhua qhov chaw ntawm lub neej.
Butyl roj hmab yog cov khoom siv roj hmab hluavtaws uas muaj huab cua zoo tshaj plaws kom deb li deb, uas yog siv dav, xws li peb cov pos hniav thiab cov pos hniav ntawm tib lub xyoo;Thaum lub raj sab hauv ntawm lub log tsheb, lub stopper ntawm lub raj mis tshuaj, thiab lwm yam yog dav siv thiab nyob rau hauv kev thov siab, qhov zoo ntawm cov khoom nyob rau hauv lub lag luam yuav tsis sib xws, thiab ib txhia txawm tsis tau piv nrog rau cov nqi ntawm asphalt.Tom qab ntawd yuav ua li cas paub qhov txawv ntawm cov roj hmab zoo butyl?Cia peb coj koj los ntawm rau yam.
1. Adhesion tuav quab yuam
Nyob rau hauv JCT 942-2004 tus qauv "butyl roj hmab waterproof sealing nplaum daim kab xev", ib tug 70 * 25mm qauv ntawm butyl daim kab xev yog muab tso rau ntawm ob daim hlau, thiab ces dai rau ntawm cov hlau phaj nrog ib kilogram hnyav.Daim kab xev butyl yuav tsum tsis txhob poob rau 20 feeb, thiab qhov ntsuas no tsim nyog.
2. Peel zog
Qhov no yog qhov tseem ceeb heev los txiav txim qhov zoo thiab qhov tsis zoo ntawm butyl roj hmab.Tus qauv yuav tsum muaj ntau dua lossis sib npaug rau 0.6n / mm, uas yog qhov kev txiav txim siab yooj yim.Tam sim no ntau yam khoom ntawm kev ua lag luam yog cov muag muag, thiab cov khoom uas tsis tsim nyog tev lub zog yuav curl yog tias muaj kev ntxhov siab me ntsis thiab qhov kub thiab txias ntawm qhov sib txuas.
3. Thaum tshav kub kub tsis kam
Raws li kev lag luam tus qauv, butyl daim kab xev yuav tsum nyob ntawm 80 ℃ rau 2 teev yam tsis muaj kev tawg, ntws thiab deformation, yog li nws tuaj yeem suav tias yog cov khoom tsim nyog.Feem ntau, cov khoom siv roj hmab butyl feem ntau yog siv rau cov vov tsev, thiab cov dej tsis zoo ntawm facade yog ntau dua;Yog tias nws ua tsis tau raws li qhov yuav tsum tau ua, cov dej tsis zoo thiab sealing kev ua tau zoo yuav raug txo kom tsawg.
4. Elastic rov qab tus nqi
Lub thiaj li hu ua elastic rov qab hais txog tias tom qab daim kab xev butyl stretched mus rau ib qho twg, nws tuaj yeem rov qab tau nws qhov shrinkage.Qhov loj dua qhov kev faib ua feem ntawm shrinkage, qhov kev ua tau zoo ntawm daim kab xev ntau dua thiab cov kua nplaum ntau dua.Yog li thaum xaiv, koj tuaj yeem sim ncab kom pom tias nws muaj zog npaum li cas.
5. Huab cua tsis kam
Aluminium zaj duab xis nyob rau saum npoo ntawm ib sab butyl daim kab xev yog tus yuam sij rau huab cua tsis kam, uas tuaj yeem cuam tshuam txog ultraviolet rays thiab ua kom lub zog ntawm daim kab xev.Qhov tseeb, daim ntawv thov ntawm butyl daim kab xev ncaj qha hauv cov tsev yog qhov zoo tshaj plaws kom tsis txhob raug.Tam sim no peb cov tsiaj feem ntau aluminized zaj duab xis sib xyaw butyl nplaum hauv khw.Tom qab ob peb lub hlis thiab txog li ib nrab xyoo, PET zaj duab xis tau raug rau cov rays ncaj qha ntawm lub hnub.Txawm hais tias aluminium ntawv ci tuaj yeem cuam tshuam UV teeb, nws tsis muaj zog.Nws yuav tawg thaum nias nrog koj cov ntiv tes, thiab PET zaj duab xis yuav tawg thaum muaj kev ntxhov siab sab nraud.
6. Chaw tsim tshuaj paus
Qhov kev xaiv zoo tshaj plaws yog xaiv cov chaw tsim khoom lag luam txhim khu kev qha thiab muaj zog los koom tes.
