3. Cov Qauv Rau Cov Thawj Coj
GB / t20474-2006 iav fiber reinforced asphalt shingles
4. Cov ntsiab lus tseem ceeb ntawm kev xaiv
4.1 Qhov dav ntawm daim ntawv thov
1) Nws siv tau rau lub ru tsev ua los ntawm cov pob zeb ua los ntawm cov pob zeb thiab lub ru tsev ntoo (lossis lub thav duab hlau). Qhov chaw ntawm lub Rooj Saib Xyuas Pob Zeb ntawm lub ru tsev nqes yuav tsum tiaj tus, thiab lub Rooj Saib Xyuas Ntoo yuav tsum raug kev kho mob tiv thaiv xeb thiab tiv thaiv kab tsuag.
2) Nws yog siv rau lub ru tsev ntawm cov tsev qis lossis ntau lub tsev nyob thiab cov tsev lag luam.
3) Nws siv tau rau lub ru tsev nrog lub nqes hav ntawm 18 ° ~ 60 °. Thaum nws yog > 60 °, cov kev ntsuas kho yuav tsum tau ua kom muaj zog.
4) Thaum siv cov vuas asphalt ib leeg xwb, nws tuaj yeem siv rau qib dej tsis nkag III (ib qho kev tiv thaiv dej tsis nkag nrog lub ncoo dej tsis nkag) thiab qib IV (ib qho kev tiv thaiv dej tsis nkag tsis muaj lub ncoo dej tsis nkag); Thaum siv ua ke, nws tuaj yeem siv rau qib dej tsis nkag I (ob txheej ntawm kev tiv thaiv dej tsis nkag thiab lub ncoo dej tsis nkag) thiab qib II (ib mus rau ob txheej ntawm kev tiv thaiv dej tsis nkag thiab lub ncoo dej tsis nkag).
4.2 cov ntsiab lus xaiv
1) Cov ntsuas tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov iav fiber reinforced asphalt vuas: lub zog tensile, tiv taus cua sov, lub zog tsim kua muag, impermeability, huab cua dag ua kom laus sai.
2) Lub ru tsev nqes hav yuav tsum tsis txhob siv cov txheej tiv thaiv dej ua txheej tiv thaiv dej lossis lub ncoo tiv thaiv dej.
3) Thaum siv cov vuas asphalt rau lub ru tsev pob zeb, cov txheej rwb thaiv tsev yuav tsum nyob saum cov txheej tiv dej, thiab cov khoom rwb thaiv tsev yuav tsum yog extruded polystyrene board (XPS); Rau cov ntoo (lossis hlau) ru tsev, cov txheej rwb thaiv tsev yuav tsum teeb tsa rau ntawm lub qab nthab, thiab cov khoom rwb thaiv tsev yuav tsum yog iav ntaub plaub.
4) Cov vuas asphalt yog cov vuas uas yoog tau, uas muaj cov kev cai nruj heev rau qhov tiaj tiaj ntawm cov hauv paus. Nws raug sim nrog 2m txoj cai qhia: qhov yuam kev tiaj tiaj ntawm qhov chaw ntawm cov txheej txheem yuav tsum tsis pub ntau tshaj 5 hli, thiab yuav tsum tsis txhob muaj qhov xoob, tawg, tev tawm, thiab lwm yam.
