Bentonite yog cov ntxhia hauv av, cov ntsiab lus tseem ceeb uas yog montmorillonite-raws li av nplaum ntxhia.Nws yog volcanic tshauv tsim los ntawm volcanic eruptions, thiab bentonite deposits yog tsim tom qab kub, siab thiab metamorphic lub sij hawm.Cov hom bentonite feem ntau muab faib ua sodium-based bentonite thiab calcium-based bentonite.Ntawm lawv, high-zoo sodium-based bentonite muaj peb yam ntxwv: siab o, tsis tshua muaj dej permeability thiab nws tus kheej-kho muaj nuj nqi, yog li nws yog dav siv nyob rau hauv ntau yam anti-seepage teb.
Waterproof thiab impermeable bentonite av nplaum yog tsim rau landfill seepage tiv thaiv, Riverside dike waterproofing, pas dej tso dej barrier, railway chaw nres tsheb engineering seepage tiv thaiv thiab foundation waterproof thiab seepage tiv thaiv ntawm ntau lub tsev.
Product Performance:
(1) Kev nthuav dav siab: bentonite nthuav dav tsawg kawg 12 zaug tom qab kev sib cuag nrog dej, ncav cuag 25 npaug ntawm ASTM D5890.
(2) Tsawg dej permeability: Cov dej permeability tsuas yog 5 X 10-9cm / sec, uas ua tau raws li ASTM D 5887 tus qauv.
(3) Kev kho tus kheej muaj nuj nqi: bentonite yuav dhau los ua gel thaum raug dej, thiab tuaj yeem sau cov kab nrib pleb thiab qhov khoob.Txoj kev sib tshooj yog qhov sib tshooj ncaj qha thiab yog li tiv taus qhov tsis sib xws geological kev sib hais haum.Nws muaj tus nqi siab ua haujlwm thiab tuaj yeem siv dav hauv ntau yam dej tsis zoo thiab kev tiv thaiv dej.
Lub waterproof, impermeable tshwj xeeb bentonite tsim los ntawm Hebei Yiheng Technology Co., Ltd. nruj me ntsis siv lub teb chaws tus qauv ntawm cov neeg koom pheej ntawm Tuam Tshoj GB/T 20973--2007 thiab manufactures.
