I-Bentonite yokungangeni kwamanzi kunye nobungqina bokuvuza koMfanekiso oBonelweyo

I-Bentonite yokungangeni kwamanzi kunye nokungavuzi

I-Bentonite yokungena kwamanzi kunye ne-anti-seepage yinto efanelekileyo engenamanzi kunye ne-impermeable material eyenziwe ngokusebenzisa i-bentonite, i-resource ye-mineral enqabileyo engeyiyo i-metallic e-China, njengeyona nto iphambili, kwaye ihlanjululwe kwaye iqhutywe ngeenkqubo ezikhethekileyo zokuvelisa ezifana nokucutshungulwa kwamaminerali, i-sodification, ukomisa kunye nokusila.Inkangeleko ingumgubo ongwevu-omhlophe okanye otyheli, osetyenziswa ikakhulu njengezinto ezingangeni manzi kunye nezixhobo ezingenamanzi kwiziseko zobunjineli ezahlukeneyo.Xa kuthelekiswa neemveliso ezifanayo, i-bentonite yokukhusela amanzi kunye ne-seepage ineempawu zokufunxa kakuhle kwamanzi, izinga eliphezulu lokunyuswa kunye nefuthe elinamandla lokugquma kwamanzi, kwaye imveliso entsha yezinto ezingenamanzi kunye nokusebenza kakuhle kokuthintela ukuvuza kunye nexabiso eliphantsi.

Umzekelo weMveliso

I-Bentonite ngumhlaba wamaminerali wendalo, inxalenye ephambili ye-montmorillonite-based clay minerals.Ingumlotha we-volcanic oveliswa ngokuqhuma kwe-volcanic, kwaye iidiphozithi ze-bentonite zenziwe emva kobushushu, uxinzelelo kunye nexesha le-metamorphic.Iindidi ze-bentonite zihlulwe kakhulu kwi-sodium-based bentonite kunye ne-calcium-based bentonite.Phakathi kwabo, i-bentonite esekelwe kwi-sodium ephezulu ineempawu ezintathu: ukuvuvukala okuphezulu, ukunyanzeliswa kwamanzi aphantsi kunye nomsebenzi wokuziphilisa, ngoko ke isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zokuchasana.

Isicelo

Udongwe lwe-bentonite olungangeni manzi kunye nolungagungqiyo lufanelekile ukukhuselwa kwe-landfill, i-dike ye-riverside i-waterproofing, i-pool yokubeka umqobo wamanzi, isikhululo sikaloliwe sokukhusela ubunjineli bobunjineli kunye nesiseko sokungangeni kwamanzi kunye nokuthintela ukuchithwa kwezakhiwo ezahlukeneyo.

Ukusebenza kwemveliso:
(1) Ukwandiswa okuphezulu: i-bentonite yandisa ubuncinane amaxesha e-12 emva kokudibana namanzi, ifikelela kumaxesha angama-25 kwi-ASTM D5890.
(2) Ukugqithiswa kwamanzi aphantsi: Ukunyanzeliswa kwamanzi yi-5 X 10-9cm / sec kuphela, edibana nomgangatho we-ASTM D 5887.
(3) Umsebenzi wokuziphilisa: i-bentonite iya kuba yi-gel xa ibonakaliswe emanzini, kwaye inokuzalisa iintanda kunye nezikhewu.Indlela yokudityaniswa kukudityaniswa okuthe ngqo kwaye ke ngoko imelana neendawo zokuhlala ezingalinganiyo.Inokusebenza kweendleko eziphezulu kwaye inokusetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo ezingenamanzi kunye ne-anti-seepage.
I-bentonite ekhethekileyo engangeni manzi, engabonakaliyo eveliswa nguHebei Yiheng Technology Co., Ltd. izalisekisa ngokungqongqo umgangatho wesizwe weRiphabhlikhi yaseChina yaseChina GB / T 20973--2007 kwaye ivelisa.
