SBS hloov bitumen membrane yog tsim los ntawm saturating puag hauv bitumen, los yog thermoplastic elastomer (xws li styrene butadiene-SBS), siv tam nrog polyester los yog fiberglass, xov lub upward lub ntsej muag nrog fine sands, mineral slates (los yog nplej) los yog Polythene membrane etc.
Yam ntxwv:
Zoo impermeability; Muaj zoo tensile zog, elongation tus nqi thiab loj stability uas yuav tsum tau zoo suited lub substrate distortion thiab tawg; SBS hloov bitumen membrane yog qhia tshwj xeeb uas tau thov nyob rau hauv lub txias hauv cheeb tsam nrog tsawg kub, thaum APP hloov bitumen membrane yog thov nyob rau hauv lub kub cheeb tsam nrog siab kub; Kev kawm zoo nyob rau hauv anti-tej, anti-broker, anti-kuj, anti-yaig, anti-pwm, anti-weathering; Siv cov kev faib yog yooj yim, cov yaj txoj kev yuav khiav lag luam nyob rau hauv plaub lub caij, pob qij txha yog txhim khu kev qha

Ii tau:
Haum rau civil tsev vuas vov tsev, underground, choj, chaw nres tsheb, pas dej ua ke, qhov nyob rau hauv txoj kab ntawm waterproofing thiab dampproof, tshwj xeeb tshaj yog rau cov tsev nyob rau hauv kub. Raws li lub ru tsev engineering stipulation, APP hloov bitumen membrane yuav siv nyob rau hauv lub Grade Ⅰ civil tsev thiab muaj lub tsev uas muaj kev tshwj xeeb waterproofing yuav tsum tau.
Cia thiab tsheb thauj mus los cov lus qhia
Thaum cia thiab tsheb thauj mus los, Ntau hom thiab ntau thiab tsawg ntawm cov khoom yuav tsum tau stacking nyias, yuav tsum tsis txhob tov. Cia kub yuav tsum tsis txhob yuav saum toj no 50 ℃, qhov siab yog tsis ntau tshaj li ob khaubncaws sab nraud povtseg, nyob rau hauv lub chav kawm ntawm tsheb thauj mus los, membrane yuav tsum sawv ntsug.
Lub stacking siab yog tsis ntau tshaj li ob khaubncaws sab nraud povtseg. Yuav kom tiv thaiv cov qaij los yog siab, thaum tsim nyog cover lub felt ntaub.
Nyob rau hauv ib txwm tej yam kev mob ntawm cia thiab tsheb thauj mus los, cia lub sij hawm yog ib xyoo txij thaum lub hnub ntawm lawm
