Kodi kusakaniza kwa bentonite mumatope obowola ndi kotani?

Kusakaniza kwa bentonite pobowola matope kumasiyana malinga ndi zofunikira zenizeni za ntchito yobowola ndi mtundu wa matope obowola omwe amagwiritsidwa ntchito. Bentonite ndi gawo lofunikira pakubowola matope, ndipo cholinga chake chachikulu ndikuwonjezera kukhuthala ndi kudzoza kwa matope. Chiŵerengero choyenera cha kusakaniza n'kofunika kwambiri kuti tikwaniritse ntchito yabwino yoboola matope.

Kawirikawiri, bentonite imasakanizidwa ndi madzi kuti ipange slurry, ndipo chiŵerengero chosakanikirana chimawonetsedwa ngati kuchuluka kwa bentonite (ndi kulemera kwake) kuwonjezeredwa kumadzi enieni. Makhalidwe ofunikira a matope obowola, monga kukhuthala, mphamvu ya gel osakaniza, ndi kuwongolera kusefera, zimakhudza kusankha kwa chiŵerengero chosakanikirana.

Zinthu zingapo zimakhudza kutsimikiza kwa chiŵerengero chosakaniza, kuphatikizapo mtundu wa bentonite wogwiritsidwa ntchito (sodium bentonite kapena calcium bentonite), mikhalidwe yobowola, ndi zofunikira zenizeni za ntchito yoboola. Izi ziyenera kuganiziridwa kuti zigwirizane ndi matope obowola kuti agwirizane ndi maonekedwe a geological of mapangidwe omwe akubowoledwa.

Sodium bentonite ndi mtundu wa bentonite womwe umagwiritsidwa ntchito pobowola matope. Chiŵerengero chosakanikirana cha dongo la sodium bentonite ndi 20 mpaka 35 mapaundi a dongo la bentonite pa malita 100 a madzi. Komabe, chiŵerengerochi chikhoza kusinthidwa kutengera zofunikira ndi mikhalidwe yoboola.

Calcium bentonite, kumbali ina, ingafunike kusakaniza kosiyana poyerekeza ndi sodium bentonite. Kusankha pakati pa sodium bentonite ndi kashiamu bentonite zimadalira zinthu monga kufunika madzimadzi katundu, salinity wa madzimadzi pobowola, ndi geological makhalidwe a mapangidwe.

Kuphatikiza pa kusakaniza koyambira, zopangira matope zimatha kukhala ndi zowonjezera zina kuti zithandizire kugwira ntchito. Zowonjezera izi zingaphatikizepo ma polima, ma viscosifiers, owongolera madzimadzi, ndi zolemetsa. Kuyanjana pakati pa bentonite ndi zowonjezera izi zimaganiziridwa bwino kuti tikwaniritse zomwe zimafunikira rheological ndi kubowola matope makhalidwe.

Ndikofunikira kuti akatswiri obowola aziyesa kuyesa kwa labotale ndi kuyesa kumunda kuti akwaniritse mikangano yosakanikirana pobowola. Cholinga chake chinali kupanga matope obowola omwe anganyamule bwino zobowola pamwamba, kupereka bata ku dzenje, ndikukwaniritsa zofunikira za chilengedwe ndi malamulo a malo obowola.

The mix chiŵerengero cha bentonite pobowola matope ndi zofunika kwambiri chizindikiro zimasiyanasiyana malinga ndi zinthu monga bentonite mtundu, pobowola zinthu ndi zofunika matope katundu. Akatswiri ogulitsa pobowola amawunika mosamala zinthu izi kuti adziwe momwe angagwiritsire ntchito pobowola, kuonetsetsa kuti pakubowola koyenera komanso kopambana.
