HydroxyethylcelluloseHECbụ polymer na-abụghị ionic mmiri soluble nke bụ soluble na ma mmiri ọkụ na oyi. Usoro Hydroxyethylcellulose HEC nwere ọtụtụ viscosities, na ngwọta mmiri bụ ihe niile na-abụghị Newtonian.
Hydroxyethyl cellulose bụ ihe mgbakwunye dị mkpa na ngwaahịa kemịkal kwa ụbọchị. Ọ nwere ike ọ bụghị naanị melite viscosity nke mmiri mmiri ma ọ bụ emulsion ịchọ mma, kamakwa mma dispersion na ụfụfụ kwụsie ike.
uru:
1. Nwere ezigbo hydration.
2. Nwere nnukwu anọgidesi na njupụta.
3. Magburu onwe film-akpụ ihe onwunwe.
4. Ọ nwere oke elu na-eri arụmọrụ.
5.Ọ nwere ọkwa dị mma nke nnọchi iji hụ na nkwụsi ike mgbochi mildew ogologo oge nke ngwaahịa ahụ.
ogo Polymerization:
E nwere atọ hydroxyl otu na nke ọ bụla anhydroglucose unit na cellulose, nke a na-emeso na alkali na aqueous sodium hydroxide ngwọta iji nweta cellulose sodium nnu, na mgbe ahụ na-enweta etherification mmeghachi omume na ethylene oxide na-etolite hydroxyethyl cellulose ether. Na usoro nke synthesizing hydroxyethyl cellulose, ethylene oxide nwere ike dochie hydroxyl otu na cellulose, na-enweta a yinye polymerization mmeghachi omume na hydroxyl iche iche na nnọchi anya otu.
Hydroxyethylcellulose nwere ezigbo hydration Njirimara. Ngwọta mmiri ya dị larịị na otu, na-enwe ezigbo mmiri na ọkwa. Ya mere, ihe ịchọ mma nwere hydroxyethyl cellulose nwere ezigbo nguzosi ike na njupụta n'ime akpa ahụ, na-agbasa ngwa ngwa na ntutu na akpụkpọ ahụ mgbe etinyere ya. A na-eji ya eme ihe na conditioners, ịsacha ahụ, ncha mmiri mmiri, gels na foams, ntacha eze, ihe mgbochi mgbochi siri ike, anụ ahụ (ụmụ ọhụrụ na ndị okenye), gels lubricating.
Na mgbakwunye na njikwa mmiri,hydroxyethyl cellulosenwere magburu onwe film akpụ Njirimara. Ihe nkiri a kpụrụ na-ekwe nkwa na ọ ga-adị na steeti zuru oke n'okpuru nyocha enyo 350x na 3500x, ọ na-ewetakwa mmetụta akpụkpọ anụ mara mma mgbe etinyere ya na ịchọ mma.
