Alkali-dawb Fiberglass Roofing Felt Rau Waterproof Membranes
Fiberglassvov tsev ntaub yog ib qho khoom siv dav siv hauv cov khoom siv alkali-dawb fiberglass ntub- pw tsaug zog, ua lub luag haujlwm tseem ceeb hauv kev tsim cov dej tsis zoo thiab rwb thaiv tsev. Nws feem ntau yog siv los ua ke nrog cov ntaub ntawv tseem ceeb hauv tsev xws li cov ntaub ntawv tsis muaj dej tsis zoo, asphalt shingles, thiab cov txheej txheem rwb thaiv tsev, ua ib qho tseem ceeb ntawm kev txhawb nqa substrate hauv lub tsev waterproofing systems.
Tus qauv nto qhov hnyav ntawm cov khoom no yog 30g / ㎡ txog 90g / ㎡. Nws cov khoom tensile yooj yim yog qhov zoo dua li cov fiberglass zoo tib yam, uas ua rau kev ua haujlwm zoo dua qub. Rau cov xwm txheej ntau lawm nrog cov kev xav tau ntawm lub zog tensile, peb tuaj yeem ntxiv cov fiberglass reinforcing threads longitudinally rau lub cev muaj zog rau kev txhawb nqa. Cov xov txuas ntxiv no yog tsim los ntawm fiberglass raw cov ntaub ntawv thiab, ntxiv rau, txhim kho tag nrho cov khoom siv ntawm lub ru tsev muaj kev xav, tshwj xeeb tshaj yog lub zog tensile ntev, uas tuaj yeem ua tau ntau dua ob npaug piv rau cov khoom siv tsis muaj zog, ua kom tau raws li qhov yuav tsum tau ua ntawm siab - load siv thiab ua.
Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, fiberglass ru tsev xav tau zoo ib yam li cov pa fiberglass nto, ob qho tib si siv mature ntub -ntev papermaking technology thiab teej tug mus rau tib series ntawm fiberglass ntub- nteg muaj cov khoom. Muaj qhov sib txawv tseem ceeb hauv qhov tsos thiab lub cev kev ntxhib los mos ntawm ob qho: fiberglass vov tsev xav yog qhov ntxhib thiab tsis tshua muaj siab dua li qhov zoo tib yam; Nyob rau tib lub sijhawm, tus nqi ntawm cov nplaum ntxiv kuj tseem ceeb dua, nrog rau cov ntsiab lus nplaum ntawm cov khoom lag luam feem ntau yog li ntawm 18% mus rau 26%, thiab cov nqi tshwj xeeb yuav raug kho raws li cov khoom hnyav.
Noj 50g / ㎡ specification vov tsev zoo li piv txwv, raws li cov qauv kev sim ntawm textile - tej thickness gauges, nws tiav thickness yog kwv yees li 0.45 hli. Cov ntaub ntawv tuab yuav muaj qhov sib txawv me ntsis vim qhov cuam tshuam ntawm cov qauv ntsuas ntsuas thiab cov qauv ntsuas. Raws li kev lag luam tus qauv piv, cov ntsiab lus nplaum ntawm qhov kev qhia tshwj xeeb no feem ntau tswj tau ntawm thaj tsam 25%, thaum lub sijhawm lub zog tensile ntev tuaj yeem ruaj khov mus txog 175N / 5cm lossis siab dua.
Los ntawm qhov kev xav ntawm kev ua tau zoo thiab cov yam ntxwv ntawm cov khoom, tus nqi tseem ceeb ntawm fiberglass vov tsev xav tias nyob rau hauv kev ntxiv dag zog rau tag nrho cov qauv ntawm cov khoom sib xyaw, muab cov khoom tiav zoo heev tsim kua muag. Cov khoom muaj ib qho tawv thiab ruaj khov zuag qhia tag nrho kev ntxhib los mos, uas yog kom meej meej distinguished los ntawm cov mos mos thiab heev nplaum zoo tib yam fiberglass nto. Vim nws qhov kev ua tau zoo ruaj khov, nws tau ntev tau siv dav hauv kev tsim khoom thiab kev ua haujlwm ntawm ntau lub tsev waterproofing thiab rwb thaiv tsev cov ntaub ntawv.
