Esikhathini lapho ukufuywa kwezilwane ezifuywayo kuchuma khona futhi ukuqaphela imvelo kusezingeni eliphezulu kakhulu,udoti wekati we-bentoniteuvele buthule njengomholi ekulinganiseni induduzo yekati, ukulula komnikazi, kanye nomthwalo wemfanelo weplanethi. Ithathwe kumaminerali obumba avela ngokwemvelo, le nkampani enamandla yokumunca ichaza kabusha imakethe yokunakekelwa kwamakati yomhlaba wonke eyizigidigidi ezingama-20 zamaRandi, okufakazela ukuthi imikhiqizo yezilwane ezifuywayo ewusizo nayo ingaba ngcono emvelweni.

Okuhlukanisa i-bentonite ukuthiamandla okufaka nokuhlanganisa angenakuqhathaniswa. Yakhiwe ngokuyinhloko nge-montmorillonite, iminerali yobumba enezimbobo eziningi, yakha izingqimba eziqinile neziqinile lapho ithinta umswakama, okwenza ukususwa kwemfucuza kube lula futhi kuhlanzeke. Ngokungafani nezingcezu zendabuko ezingagcwali ezidinga ukuguqulwa kwetreyi ephelele, i-bentonite ivumela ukuhlanzwa kwamabala, inciphise imfucuza yemfucuza ngamaphesenti angama-60 ngokuhamba kwesikhathi. Lokhu kusebenza kahle akugcini nje ngokusindisa imali kubanikazi bezilwane ezifuywayo kodwa futhi kunciphisa inani lemfucuza ethunyelwa ezindaweni zokulahla udoti.

Ngaphandle kokusebenza kahle, udoti wekati we-bentonite wenza intuthuko enkuluukusimama. Imikhiqizo eminingi ehamba phambili manje ithola ubumba lwayo ezimayini eziphethwe ngendlela efanele, inamathela ezindinganisweni eziqinile zokuvuselela kabusha ezibuyisela imvelo ngemva kokukhipha. Ubuchwepheshe bokucubungula bunciphise nokusetshenziswa kwamanzi namandla, kuyilapho izinhlobo ezibolayo nezihlanzwayo zithola ukudonswa. Le mikhiqizo iyawohloka ngokwemvelo ezinhlelweni zamanzi amdaka, isusa isidingo sezinto zokufaka udoti zepulasitiki futhi inciphisa imfucuza yepulasitiki esetshenziswa kanye.

Izinzuzo zezempilo nokuphepha ze-bentonite ziqinisa isikhundla sayo njengokukhetha okuphezulu. Ukwakheka kwayo kwemvelo akunawo amakha okwenziwa, udayi, kanye nezithasiselo zamakhemikhali, okwenza kube kuhle kakhulu kumakati anesikhumba esibucayi noma izinkinga zokuphefumula. Isenzo sokuhlanganisana sibamba namaphunga ngempumelelo ngaphandle kokuthembela kumakha aqinile, okudala indawo entsha kokubili ezifuywayo kanye nabangane bazo abangabantu.

Izitayela zakamuva zemakethe zibonisa isidingo esikhulayo se-ukwakheka okukhethekile kwe-bentoniteIzinketho ezingabangeli ukungezwani komzimba, ezenzelwe ukunciphisa uthuli kanye nezinto ezibangela ukungezwani komzimba, zithandwa kakhulu emindenini enezilwane eziningi ezifuywayo noma amalungu omndeni anezinkinga zokungezwani komzimba. Okwamanje, ama-bentonite litter alula, asebenzisa izinhlayiya zobumba ezinwetshiwe, anikeza ukuphathwa okulula kanye nokunciphisa ukukhishwa kwekhabhoni ngesikhathi sokuthuthwa.

Ukukhiqizwa komhlaba wonke kugxile ezifundeni ezibalulekile ezinezinsalela zobumba ezicebile, okuhlanganisa i-United States, i-China, i-Germany, ne-Turkey. Abakhiqizi baseShayina, ikakhulukazi, batshale imali eningi ocwaningweni nasekuthuthukisweni, bekhiqiza ama-bentonite litter asezingeni eliphezulu futhi angabizi kakhulu abusa izimakethe zasekhaya nezamazwe ngamazwe.

Njengoba abanikazi bezilwane ezifuywayo beqhubeka nokubeka phambili ukusimama ngaphandle kokubeka engcupheni ukusebenza kahle, udoti wekati we-bentonite ungaphezu nje komkhiqizo wokunakekelwa kwezilwane ezifuywayo—kuyintouphawu lobuhlobo obuguqukayo phakathi kwabantu, izilwane kanye nemveloNjengoba kunezindlela ezintsha eziqhubekayo zokubola kwezinto eziphilayo, ukunciphisa uthuli, kanye nemikhuba yomnotho ojikelezayo, ikulungele ukuhola indlela ekudaleni ikusasa eliluhlaza kubangani bethu bekati kanye nomhlaba esiwabelana ngawo.
