Njupụta nke Bentonite Slurry
1. Nhazi na arụmọrụ nke slurry
1.1 Nhazi
Bentonite, nke a makwaara dị ka nkume bentonite, bụ nkume ụrọ nke na-egosipụta pasentị dị elu nke montmorillonite, nke na-enwekarị obere ego nke illite, kaolinite, zeolite, feldspar, calcite, wdg. Bentonite nwere ike ekewa n'ime ụdị atọ: bentonite dabeere na sodium (ala alkaline), ala bentonite nke dabeere na calcium (alkaline ala), ala ala bentonite (alkaline ala). N'ime ha, bentonite dabeere na calcium nwere ike ekewa n'ime calcium-sodium dabeere na calcium-magnesium dabeere bentonites, kwa.
1.2 Arụmọrụ
1) Njirimara anụ ahụ
Bentonite na-acha ọcha na ìhè odo na eke mgbe ọ na-egosikwa na ìhè isi awọ, ìhè green pink, aja aja-acha uhie uhie, nwa, wdg Bentonite dịgasị iche iche na stiifness ruru ha anụ ahụ Njirimara.
2) Ngwakọta kemịkalụ
Ihe ndị bụ isi kemịkalụ nke bentonite bụ silicon dioxide (SiO2), aluminum oxide (Al2O3) na mmiri (H2O). Ọdịnaya nke ígwè oxide na magnesium oxide na-adịkwa elu mgbe ụfọdụ, na calcium, sodium, potassium na-adịkarị na bentonite na ọdịnaya dị iche iche. Ọdịnaya nke Na2O na CaO na bentonite na-eme ka ọdịiche dị na anụ ahụ na nke kemịkal, na ọbụna nhazi teknụzụ.
3) Njirimara anụ ahụ & kemịkalụ
Bentonite pụtara na hygroscopicity kachasị mma, ya bụ mgbasawanye mgbe nnabata mmiri gasịrị. Ọnụọgụ mgbasawanye nke metụtara mmịnye mmiri ruru elu ruo ugboro 30. Enwere ike ịgbasa ya na mmiri ka ọ bụrụ nkwusioru nke viscous, thixotropic na mmanu colloidal. Ọ na-aghọ nke na-adịghị mma na nrapado ka agwakọta ya na ezigbo irighiri ihe dị ka mmiri, slurry ma ọ bụ ájá. Ọ na-enwe ike ịmịkọrọ gas dị iche iche, mmiri mmiri na ihe ndị dị ndụ, na ikike mgbasa ozi kachasị nwere ike iru ugboro ise n'ịdị arọ ya. Ụwa nke na-eme ka acid dị n'elu nwere ike ịmịnye ihe ndị nwere agba.
Njirimara anụ ahụ na kemịkal nke bentonite dabere na ụdị na ọdịnaya nke montmorillonite ọ nwere. N'ozuzu, bentonite nke dabeere na sodium nwere ihe anụ ahụ na kemịkal dị elu na arụmọrụ teknụzụ karịa calcium dabeere na bentonite ma ọ bụ magnesium.
