Bentonite ndi mchere wosakhala wachitsulo wokhala ndi montmorillonite ngati gawo lalikulu la mchere. Kapangidwe ka montmorillonite ndi kapangidwe ka kristalo ka mtundu wa 2:1 kopangidwa ndi ma tetrahedrons awiri a silicon oxygen okhala ndi wosanjikiza wa aluminiyamu oxide octahedron. Chifukwa kapangidwe ka magawo komwe kamapangidwa ndi selo la montmorillonite kali ndi ma cations ena, monga Cu, Mg, Na, K, ndi zina zotero, ndipo ntchito ya ma cations awa ndi selo la montmorillonite ndi yosakhazikika, yosavuta kusinthana ndi ma cations ena, ili ndi mphamvu yabwino yosinthira ma ion. Kunja, yagwiritsidwa ntchito m'madipatimenti opitilira 100 m'magawo 24 opanga mafakitale ndi ulimi, yokhala ndi zinthu zoposa 300, chifukwa chake anthu amaitcha "nthaka yapadziko lonse".

Bentonite imadziwikanso kuti bentonite, bentonite, kapena bentonite. China ili ndi mbiri yayitali yopangira ndikugwiritsa ntchito bentonite, yomwe poyamba inkagwiritsidwa ntchito ngati sopo wothira madzi. Panali migodi yotseguka m'dera la Renshou ku Sichuan zaka mazana ambiri zapitazo, ndipo anthu am'deralo ankatcha bentonite kuti ufa wa dongo. Imagwiritsidwa ntchito kwambiri koma ili ndi mbiri ya zaka zoposa zana. Kupezeka koyamba ku United States kunali m'magawo akale a Wyoming. Dongo la chartreuse limatha kukula kukhala phala atawonjezera madzi. Pambuyo pake, anthu adatcha dongo lonse lokhala ndi izi bentonite. Ndipotu, mchere waukulu wa bentonite ndi montmorillonite, wokhala ndi 85-90%. Makhalidwe ena a bentonite amatsimikiziridwanso ndi montmorillonite. Montmorillonite ikhoza kukhala ndi mitundu yosiyanasiyana, monga wobiriwira wachikasu, woyera wachikasu, imvi, woyera, ndi zina zotero. Imatha kupanga mabuloko okhuthala kapena nthaka yotayirira, yokhala ndi kumverera koterera ikakanda ndi zala. Pambuyo powonjezera madzi, kuchuluka kwa mabuloko ang'onoang'ono kumawonjezeka kangapo mpaka nthawi 20-30, kumawonekera ngati wopachikidwa m'madzi, komanso ngati phala pamene madzi ali ochepa. Chikhalidwe cha montmorillonite chikugwirizana ndi kapangidwe kake ka mankhwala ndi kapangidwe kake ka mkati.

Kugwiritsa ntchito bentonite:
Choyamba: Makampani opanga mankhwala tsiku ndi tsiku
1. Ufa wa bentonite wabwino umagwiritsidwa ntchito mu zodzoladzola, zomwe zingagwiritsidwe ntchito ngati zinthu zoyambira pakukongoletsa, kusamalira khungu, nsidze, komanso kuchotsa makwinya. Kuchuluka kwa ntchito ndi kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito zikuchulukirachulukira. Zikuoneka kuti msika ukuvomerezedwa kwambiri ndi zinthu zomwe zawonjezeredwa ufa wa bentonite wabwino.

2. Zotsukira zopangidwa ndi bentonite zimakhala ndi mphamvu yosinthana ma ion ambiri, ndipo panthawi yoteteza chilengedwe, mtundu uwu wa chotsukira cha bentonite sudzawononga chilengedwe ngakhale mutagwiritsa ntchito, zomwe zimapangitsa kuti chikhale chotsukira choyenera kwambiri chotsukira zovala.

3. Bentonite yowonjezeredwa ku shampu iyenera kuyeretsedwa. Bentonite yoyeretsedwa bwino kwambiri imatha kusintha thixotropy ndi kukhuthala kwa shampu. Ngakhale ikukweza luso lake logwiritsa ntchito, ilinso ndi ntchito ziwiri zoyeretsa komanso kuteteza malamulo.

Chachiwiri: Kukonza chakudya

Chifukwa cha kukhuthala kwake komanso kusinthasintha kwa mtundu, bentonite nthawi zambiri imagwiritsidwa ntchito ngati choyeretsera ndi kuchotsa utoto m'mafuta odyedwa ndi nyama ndi zomera.

Chachitatu: Kuteteza Chilengedwe
Chifukwa cha kufalikira kwake bwino, kukula kwake kochepa kwa tinthu, komanso kuthekera kwake kusungunuka, bentonite ingagwiritsidwenso ntchito ngati choyeretsera zinyalala ndi kusungunuka, komanso ngati chinthu chatsopano choteteza chilengedwe.
