Nwere ike hypromellose dochie hydroxyethyl cellulose na ezigbo nkume agba

A na-enweta ngwaahịa cellulose site na pulp owu eke ma ọ bụ pulp osisi site na etherification.Ngwaahịa cellulose dị iche iche na-eji ihe etherifying dị iche iche.Hypromellose HPMC na-eji ụdị etherifying ndị ọzọ (chloroform na 1,2-epoxypropane), ebe hydroxyethyl cellulose HEC na-eji Oxirane etherifying agents.Enwere ike iji hydroxyethyl cellulose dị ka thickener na ezigbo nkume agba na latex agba.N'ihi na nke nnukwu ego nke mkpokọta, kpọmkwem ike ndọda, ọdịda, ọ kwesịrị ka ịgbakwunye ndim gị n'ụlọnga na-amụba ya viscosity, iji gboo mkpa nke ewu ịgba viscosity, na mma ya nchekwa kwụsie ike, na iji nweta a ụfọdụ ike.Iji nweta ike dị mma, ezigbo mmiri na-eguzogide na ihu igwe, nhọrọ nke akụrụngwa na nhazi nhazi dị ezigbo mkpa.

N'ozuzu, ego nke elu-edu ezigbo nkume agba emulsion ga-adị elu.Dịka ọmụmaatụ, otu ton nke ezigbo nkume agba nwere ike ịnwe kilogram 300 nke emulsion dị ọcha na 650 n'arọ nke ájá nkume nwere agba.Mgbe ọdịnaya siri ike nke emulsion bụ 50%, olu nke 300 kg emulsion mgbe ihichachara bụ ihe dị ka lita 150, 650 Kg nke ájá dị ihe dịka 228 lita.Ya bụ, n'oge a PVC (pigmenti olu ntinye uche) nke ezigbo nkume agba bụ 60% , n'ihi na akụkụ nke ájá na-acha acha dị ukwuu na nke na-adịghị agbanwe agbanwe n'ụdị, n'okpuru ọnọdụ nke ụfọdụ nkesa nha, mgbe ihicha. ezigbo nkume agba nwere ike ịbụ na CPVC (dị oké egwu pigmenti olu ịta) banyere.Maka thickener, ọ bụrụ na ahọpụtara viscosity kwesịrị ekwesị nke cellulose, enwere ike ịmepụta ihe nkiri zuru oke na nke siri ike iji zute ihe atọ dị mkpa maka ịrụ ọrụ nke ezigbo nkume agba.Ọ bụrụ na ọdịnaya nke emulsion dị ala, a na-atụ aro ka ị jiri viscosity dị elu nke cellulose dị ka onye na-agba ume (dịka ọmụmaatụ 100,000 viscosity), karịsịa mgbe ọnụahịa nke cellulose na-abawanye, nke nwere ike ibelata ọnụ ọgụgụ nke cellulose eji, nwekwara ike ikwe ka arụmọrụ. nke ezigbo nkume agba ka elu .Ụfọdụ ndị na-emepụta ihe osise nkume dị ọnụ ala ejiriwo hypromellose dochie hydroxyethyl cellulose n'ihi ọnụ ahịa na ihe ndị ọzọ.E jiri ya tụnyere ụdị cellulose abụọ ahụ, hydroxyethyl cellulose nwere ikike ijide mmiri ka mma, ọ dịghị atụfu ikike ijide mmiri n'ihi gel na okpomọkụ dị elu, ma nwee ụfọdụ mgbochi mildew.N'ihi arụmọrụ, a na-atụ aro ka iji 100,000 viscosity hydroxyethyl cellulose dị ka thickener nke ezigbo nkume agba.
