Hydroxyethyl Cellulose (HEC) bụ polymer soluble mmiri nke a na-ejikarị dị ka thickener, emulsifier, stabilizer, wdg.
Usoro mgbasa nke Hydroxyethyl Cellulose
Kwadebe ihe na akụrụngwa:
Hydroxyethyl cellulose ntụ ntụ
Ihe mgbaze (na-abụkarị mmiri)
Ngwa mkpali (dị ka igwe mkpali)
Ngwa eji atụ ihe (ịtụ cylinder, itule, wdg)
Akpa
Na-ekpo ọkụ ihe mgbaze:
Iji mee ka usoro mgbasa ozi dị ngwa, ihe mgbaze nwere ike ikpo ọkụ nke ọma, mana n'ozuzu ekwesịghị gafere 50 Celsius C iji zere mmebi okpomọkụ nwere ike ime. Okpomọkụ mmiri dị n'etiti 30°C na 50°C dị mma.
Jiri nwayọọ tinye HEC ntụ ntụ:
Jiri nwayọ fesa ntụ ntụ HEC n'ime mmiri ọkụ. Iji zere agglomeration, tinye ya na sieve ma ọ bụ jiri nwayọọ nwayọọ fesa ya. Jide n'aka na HEC ntụ ntụ na-agbasasị nke ọma n'oge usoro mkpali.
Gaa n'ihu na-akpali:
N'oge usoro mkpali, nọgide na-eji nwayọọ nwayọọ tinye HEC ntụ ntụ iji hụ na ntụ ntụ na-agbasasị na mmiri. Ọsọ mkpali ekwesịghị ịdị ngwa ngwa iji gbochie afụ na agglomeration. A na-akwadokarị ịkpali ọsọ nke ọkara.
Mgbasa na-eguzosi ike: Mgbe mgbasasị zuru oke, ọ na-adịkarị mkpa iguzo ruo oge (na-abụkarị ọtụtụ awa ma ọ bụ karịa) iji kwe ka HEC gbazee kpamkpam ma mepụta ngwọta edozi. Oge nkwụsị na-adabere na ịdị arọ molekụla nke HEC na ntinye nke ngwọta.
Ịgbanwe viscosity: Ọ bụrụ na ọ dị mkpa ka a gbanwee viscosity, ọnụọgụ HEC nwere ike ịbawanye ma ọ bụ belata nke ọma. Tụkwasị na nke ahụ, a pụkwara imezi ya site n'ịgbakwunye electrolytes, ịgbanwe pH uru, wdg.
Akpachara anya na mgbasa
Zere agglomeration: Hydroxyethyl cellulose dị mfe agglomerate, yabụ mgbe ị na-agbakwunye ntụ ntụ, kpachara anya ka ị fesaa ya nke ọma. Enwere ike iji sieve ma ọ bụ ngwaọrụ ọzọ na-ekesa iji nyere aka gbasasịa.
Okpomọkụ nchịkwa: Okpomọkụ ihe mgbaze ekwesịghị ịdị elu, ma ọ bụghị ya, ọ nwere ike ịkpata mmebi okpomọkụ nke HEC ma na-emetụta arụmọrụ nke ngwọta. Ọ na-adịkarị mma ijikwa ya n'etiti 30°C na 50°C.
Gbochie ikuku ịbanye: Zere ịkpali ngwa ngwa iji gbochie ikuku ịbanye na ngwọta iji mepụta afụ. Afụ ga-emetụta ịdị n'otu na nghọta nke ngwọta.
Họrọ akụrụngwa mkpali ziri ezi: Họrọ akụrụngwa mkpali ziri ezi dịka viscosity nke ngwọta si dị. Maka ngwọta dị ala viscosity, a pụrụ iji ndị na-akpali akpali nkịtị; maka ngwọta viscosity dị elu, enwere ike ịchọ onye na-akpali akpali.
Nchekwa na ichekwa:
Ekwesịrị ịchekwa ihe ngwọta HEC gbazere n'ime akpa mkpuchi iji gbochie mmiri ma ọ bụ mmetọ. Mgbe echekwara ya ogologo oge, zere ìhè anyanwụ kpọmkwem na ọnọdụ okpomọkụ dị elu iji hụ na nkwụsi ike nke ngwọta.
Ọtụtụ nsogbu na ngwọta
Mgbasa na-ekwekọghị ekwekọ:
Ọ bụrụ na mgbasa na-enweghị isi emee, ọ nwere ike ịbụ n'ihi na a na-efesa ntụ ntụ ngwa ngwa ma ọ bụ kpalie ya nke ọma. Ihe ngwọta bụ imeziwanye ịdị n'otu nke ịkpali, mee ka oge na-akpali akpali, ma ọ bụ gbanwee ọsọ nke mgbakwunye ntụ ntụ n'oge mkpali.
Ọgbọ afụ:
Ọ bụrụ na ọnụ ọgụgụ buru ibu nke afụ na-apụta na ngwọta, enwere ike ibelata ụfụfụ ahụ site n'ibelata ọsọ na-akpali akpali ma ọ bụ ikwe ka ọ guzoro ogologo oge. Maka afụ nke emepụtalarị, a pụrụ iji onye na-emepụta ihe na-emepụta ihe ma ọ bụ ọgwụgwọ ultrasonic wepụ ha.
Viscosity ngwọta dị oke elu ma ọ bụ dị ala:
Mgbe viscosity ngwọta na-emezughị ihe ndị a chọrọ, enwere ike ịchịkwa ya site n'ịgbanwe ọnụọgụ HEC. Na mgbakwunye, imezi uru pH na ike ionic nke ngwọta nwekwara ike imetụta viscosity.
Ị nwere ike igbari hydroxyethyl cellulose nke ọma wee nweta ngwọta edo na nke kwụsiri ike. Ịmụta usoro ọrụ ziri ezi na ịkpachapụ anya nwere ike ịbawanye mmetụta nke hydroxyethyl cellulose na ngwa dị iche iche.
