Dab tsi yog bentonite waterproof pam ua los ntawm:
Cia kuv xub tham txog dab tsi yog bentonite. Bentonite hu ua montmorillonite. Raws li nws cov qauv tshuaj, nws tau muab faib ua calcium-based thiab sodium-based. Cov yam ntxwv ntawm bentonite yog tias nws swells nrog dej. Thaum calcium-based bentonite swells nrog dej, nws tuaj yeem ncav cuag nws tus kheej ntim. Sodium bentonite tuaj yeem nqus tau tsib zaug nws qhov hnyav thaum nws swells nrog dej, thiab nws qhov ntim nthuav dav mus txog ntau dua 20-28 npaug ntawm nws lub ntim. Vim hais tias cov expansion coefficient ntawm sodium bentonite waterproof pam yog siab dua, nws yog tam sim no siv ntau dua. . Cov sodium bentonite yog kaw nyob rau hauv nruab nrab ntawm ob txheej ntawm geosynthetics (hauv qab yog woven geotextile, thiab sab sauv yog luv-filament geotextile), uas plays lub luag hauj lwm ntawm kev tiv thaiv thiab ntxiv dag zog. Cov ntaub ntawv pam vov ua los ntawm non-woven koob xuas nrig ntaus ua rau GCL muaj ib qho tag nrho shear zog.
Qhov zoo ntawm bentonite waterproof pam:
1: Compactness: Tom qab sodium bentonite swells nyob rau hauv dej, nws yuav tsim ib tug high-density daim nyias nyias nyob rau hauv dej siab, uas yog sib npaug rau 100 npaug ntawm compactness ntawm 30cm tuab av nplaum, thiab muaj zog tuav dej.
2: Waterproof: Txij li thaum bentonite yog muab los ntawm cov xwm thiab siv nyob rau hauv cov xwm, nws yuav tsis aging los yog corroded tom qab ib tug ntev lub sij hawm los yog ib puag ncig ib puag ncig hloov, yog li ntawd lub waterproof kev ua tau zoo nyob ntev. Tab sis nws tsis tuaj yeem siv rau hauv high-concentration electrolyte tov waterproofing thiab anti-seepage tej yaam num.
3: Kev ncaj ncees: kev sib koom ua ke ntawm bentonite waterproof daim pam thiab hauv qab ib puag ncig. Tom qab cov sodium bentonite swells nrog dej, nws tsim lub cev compact nrog rau hauv qab ib puag ncig, tuaj yeem hloov mus rau qhov tsis sib xws, thiab tuaj yeem kho cov kab nrib pleb ntawm sab hauv hauv 2 hli.
4: Ntsuab thiab kev tiv thaiv ib puag ncig: Txij li thaum bentonite raug coj los ntawm xwm, nws yuav tsis cuam tshuam rau ib puag ncig thiab tib neeg.
5: Kev cuam tshuam rau kev tsim kho ib puag ncig: Tsis cuam tshuam los ntawm cua daj cua dub thiab huab cua txias. Txawm li cas los xij, vim yog cov khoom o ntawm bentonite hauv kev sib cuag nrog dej, kev tsim kho tsis tuaj yeem ua rau hnub los nag.
6: Kev tsim kho yooj yim: Piv nrog rau lwm cov ntaub ntawv geotechnical, bentonite waterproof pam yog yooj yim los tsim thiab tsis tas yuav tsum tau vuam. Koj tsuas yog yuav tsum tau nchuav bentonite hmoov rau ntawm qhov sib tshooj thiab kho nws nrog rau tes.
Lub hom phiaj ntawm bentonite waterproof pam:
Tshwj xeeb yog siv rau hauv cov pas dej cuav, cov dej hauv dej, cov chaw pov tseg, cov chaw nres tsheb hauv av, kev tsim kho hauv av, cov vaj tsev hauv av, cov pas dej, cov roj depots, cov chaw khaws tshuaj lom neeg thiab lwm yam dej num los daws cov kev sib khi, kev sib cais, thiab cov teeb meem los tiv thaiv, thiab muaj zog tiv thaiv kev puas tsuaj, cov nyhuv yog zoo heev.
