Kachulukidwe: Sodium bentonite imapanga diaphragm yapamwamba kwambiri pansi pa madzi. Pamene makulidwe ali pafupifupi 3mm, madzi ake permeability ndi α×10 -11 m/sekondi kapena kucheperapo, amene ali ofanana 100 nthawi compactness 30cm dongo wandiweyani. Kuchita mwamphamvu kodziteteza. Lili ndi ntchito yosatha madzi: Chifukwa sodium-based bentonite ndi zinthu zakuthupi, sizimayambitsa ukalamba kapena dzimbiri ngakhale patapita nthawi yaitali kapena kusintha kwa malo ozungulira, kotero kuti madzi osagwira ntchito amakhala olimba. Kumanga kosavuta ndi nthawi yochepa yomanga: Poyerekeza ndi zipangizo zina zopanda madzi, zomangamanga ndizosavuta ndipo sizifuna kutentha ndi kumata. Mwachidule kugwirizanitsa ndi kukonza ndi bentonite ufa ndi misomali, gaskets, etc. Palibe kufufuza kwapadera komwe kumafunika pambuyo pomanga, ndipo n'kosavuta kukonzanso ngati kumapezeka kuti sikungalowe madzi. GCL ndiye nthawi yayifupi kwambiri yomanga pazinthu zomwe zilipo zopanda madzi. Osakhudzidwa ndi kutentha: sikudzakhala brittle nyengo yozizira. Kuphatikiza kwa zinthu zopanda madzi ndi chinthu: Pamene sodium bentonite imachita ndi madzi, imakhala ndi mphamvu yotupa nthawi 13-16. Ngakhale mawonekedwe a konkire agwedezeka ndikukhazikika, bentonite mu GCL imatha kukonza ming'alu pa konkire mkati mwa 2mm. Chitetezo chobiriwira ndi chilengedwe: Bentonite ndi zinthu zachilengedwe zomwe zilibe vuto komanso zopanda poizoni m'thupi la munthu, sizimakhudza kwambiri chilengedwe, ndipo zimakhala ndi chitetezo chabwino cha chilengedwe.
