Ntụle nke Ngwongwo Nkwụsị Mgbochi Mmiri nke Polyanionic cellulose Mepụtara site na Usoro Mgwakota agwa na Usoro Slurry.

Polyanionic cellulose (PAC) bụ polymer soluble mmiri nke ewepụtara na cellulose ma na-ejikarị ya dị ka ihe mgbakwunye na-achịkwa ọnwụ mmiri n'ime mmiri na-egwupụta ihe na-eji mmanụ na gas eme nchọpụta. Ụzọ abụọ bụ isi nke ịmepụta PAC bụ usoro ntụ ọka na usoro slurry. Nke a bụ ntụnyere akụrụngwa na-eguzogide mmiri mmiri nke PAC mepụtara site na usoro abụọ a:

1. Usoro mgwakota agwa:
   • Usoro mmepụta: N'ime usoro mgwakota agwa, a na-emepụta PAC site n'imeghachite cellulose na alkali, dị ka sodium hydroxide, iji mepụta mgwakota agwa cellulose alkaline. A na-eji chloroacetic acid meghachi mgwakota agwa a iji webata otu carboxymethyl n'ime ọkpụkpụ azụ cellulose, na-ebute PAC.
   • Nha urughuru: PAC nke usoro mgwakota agwa na-emepụta na-enwekarị oke urughuru ma nwee ike ịnwe agglomerates ma ọ bụ nchịkọta nke irighiri ihe PAC.
   • Mgbochi Mbelata mmiri mmiri: PAC nke usoro mgwakota agwa na-emepụta n'ozuzu na-egosipụta ezigbo nkwụsi ike nke mmiri na-agbapụta mmiri. Otú ọ dị, nnukwu urughuru size na nwere ike ọnụnọ nke agglomerates nwere ike ime ka iji nwayọọ hydration na mgbasa na mmiri na-egwuputa mmiri mmiri, nke nwere ike imetụta mmiri ọnwụ njikwa arụmọrụ, karịsịa na elu okpomọkụ na elu-nrụgide ọnọdụ.
2. Usoro slurry:
   • Usoro mmepụta: N'ime usoro slurry, cellulose na-ebu ụzọ gbasasịa n'ime mmiri iji mepụta slurry, nke a na-emeghachi ya na sodium hydroxide na chloroacetic acid iji mepụta PAC ozugbo na ngwọta.
   • Oke urughuru: PAC na-emepụta site na slurry usoro a na-enwe a nta urughuru size na bụ ihe uniformly achụsasịwo na ngwọta tụnyere PAC emepụtara site mgwakota agwa usoro.
   • Mgbochi Mbelata mmiri mmiri: PAC nke usoro slurry na-emepụta na-egosipụta ọmarịcha nguzogide mfu mmiri n'ime mmiri na-egwupụta ihe. The nta urughuru size na edo mgbasa na-akpata ngwa ngwa hydration na mgbasa na mmiri na-egwuputa mmiri mmiri, na-eduga mma ọmụmụ ọnwụ njikwa arụmọrụ, karịsịa na ihe ịma aka ikupu ọnọdụ.

ma PAC nke usoro mgwakota agwa na-emepụta na PAC nke usoro slurry na-emepụta nwere ike inye ihe mgbochi mmiri dị irè n'ịgba mmiri. Otú ọ dị, PAC nke usoro slurry na-emepụta nwere ike inye ụfọdụ uru, dị ka hydration ngwa ngwa na mgbasa ozi, na-eduga n'ịrụ ọrụ nchịkwa nchịkwa nke mmiri mmiri, karịsịa na ebe okpomọkụ dị elu na nke dị elu. N'ikpeazụ, nhọrọ n'etiti ụzọ mmepụta abụọ a nwere ike ịdabere na ihe ndị chọrọ ịrụ ọrụ kpọmkwem, ihe ndị na-eri ego, na ihe ndị ọzọ dị mkpa maka ngwa mmiri mmiri.
