Daim ntawv thov ntawm cov khoom los ntawm lub thawv ntim cov tuam txhab tau txhim kho cov ntim khoom ntawm cov khoom siv plua plav thiab ua rau kev thauj mus los yooj yim dua. Lub hnab ntim khoom tau siv dav hauv kev lag luam cement.
Ua ntej tshaj plaws, txhawm rau tiv thaiv kom tsis txhob ya raws, lub hnab ntim khoom tuaj yeem muab cov ntaub ntawv los yog coated woven npuag sab hauv kom ua tau raws li cov yam ntxwv ntawm cov cement uas ntshai tsam ya raws. Lub hnab ntim khoom lag luam tseem tuaj yeem tsim cov thawv ntim khoom raws li cov khoom lag luam morphological thiab cov kev thauj mus los kom tau raws li cov khoom xav tau kev thauj mus los.
Qhov thib ob, thaum sau cov cement, FIBC cov chaw tsim khoom tsim cov qhov hauv cov khoom siv hauv ob sab phlu los daws qhov teeb meem huab cua permeability. Los ntawm kev siv thev naus laus zis, kev ua haujlwm tsis zoo ntawm cov khoom pov thawj ntawm lub hnab tuj yog qhov zoo dua.
Los ntawm txoj hlua khi lub hnab ntim nrog PE, qhov kub ntawm lub hnab ntim tuaj yeem txhim kho zoo dua, thiab cov cua kub qis yuav ruaj khov yam tsis muaj kev puas tsuaj rau lub hnab ntim.
