Cov txheej saum toj kawg nkaus ntawm daim pam tsis muaj dej tsis muaj dej yog cov yeeb yaj kiab siab polyethylene (HDPE) thiab cov txheej qis yog cov ntaub tsis-woven. Sodium bentonite waterproof pam nrog zoo waterproof nyhuv yog tsau ntawm high-strength geotextiles siv ib tug tshwj xeeb koob punching txoj kev thiab ces muab tso rau ntawm cov ntaub ntawv uas tsis yog-woven. Ib txheej ntawm high-density polyethylene (HDPE) zaj duab xis yog adhered rau nws. Bentonite waterproof pam muaj zog waterproof thiab anti-seepage muaj peev xwm tshaj li bentonite waterproof pam. Lub tshuab ua dej tsis zoo yog tias cov khoom bentonite nthuav dav thaum raug dej, tsim kom muaj lub cev sib xws. Raws li kev txwv ntawm ob txheej ntawm geotextile, bentonite nthuav tawm los ntawm kev tsis sib haum xeeb rau kev txiav txim. Qhov tshwm sim ntawm kev nqus dej tas li thiab nthuav dav yog ua kom cov bentonite txheej nws tus kheej ntom. , yog li muaj cov nyhuv waterproof.
Lub cev yam ntxwv ntawm coated waterproof pam:
1. Nws muaj cov dej tsis zoo thiab tiv thaiv cov dej tsis zoo, cov dej ntws los tiv thaiv dej tuaj yeem ncav cuag ntau dua 1.0MPa, thiab cov permeability coefficient yog 5 × 10-9cm / s. Bentonite yog cov khoom siv ntuj tsim tsis muaj zog uas yuav tsis raug kev laus cov tshuaj tiv thaiv thiab muaj kev ua haujlwm zoo; thiab nws yuav tsis muaj kev cuam tshuam tsis zoo rau ib puag ncig yog cov khoom siv tsis zoo rau ib puag ncig
2. Nws muaj tag nrho cov yam ntxwv ntawm cov ntaub ntawv geotextile, xws li kev sib cais, kev txhawb zog, kev tiv thaiv, pom, thiab lwm yam. Nws yog ib qho yooj yim rau kev tsim thiab tsis txwv los ntawm kev tsim kho qhov kub thiab txias. Nws tseem tuaj yeem tsim kho hauv qab 0 ℃. Thaum lub sij hawm tsim kho, koj tsuas yog yuav tsum tau nteg lub GCL waterproof pam ca rau hauv av. Thaum tsim lub façade lossis txoj kab nqes, kho nws nrog cov ntsia hlau thiab cov ntxhua khaub ncaws, thiab sib tshooj raws li qhov xav tau.
3. Yooj yim kho; Txawm tias tom qab kev tsim kho dej (seepage) ua tiav, yog tias cov txheej txheem dej tsis sib haum xeeb raug puas tsuaj, tsuav yog qhov kev puas tsuaj tsuas yog kho, qhov ua tau zoo ntawm cov dej tsis zoo tuaj yeem rov qab tau.
4. Qhov kev ua tau zoo-tus nqi piv yog qhov siab thiab nws muaj ntau yam kev siv.
5. Cov khoom dav tuaj yeem ncav cuag 6 meters, uas phim cov khoom siv thoob ntiaj teb geotextile (membrane) specifications, zoo heev txhim kho kev tsim kho efficiency.
6. Nws yog qhov tsim nyog rau kev kho cov dej ntws tawm thiab cov dej ntws tawm hauv cov cheeb tsam uas muaj kev tiv thaiv dej ntau dua thiab tiv thaiv cov dej ntws tawm, xws li cov tunnels, subways, hauv qab daus, cov kab hauv av, ntau lub tsev hauv av thiab cov dej num hauv av nrog cov dej hauv av nplua nuj.
