Hydroxyethyl cellulose (HEC) na hydroxypropyl methyl cellulose (HPMC) bụ ihe abụọ a na-ejikarị eme ihe.Ha bụ ihe na-agbanwe agbanwe nke enwere ike iji nye nguzogide, ịbawanye viscosity, ma ọ bụ nye ductility.Ngwakọta kemịkalụ ha yiri, mana enwere ụfọdụ ọdịiche doro anya.
HEC bụ analọg ethylene-acetate nke gụnyere formaldehyde, methanol na sodium hydroxide.Ọ bụ thixotropic nke ukwuu na enwere ike iji ya dị ka mmanụ mmanu, ndị na-ahụ maka ọgwụgwọ elu na nrapado maka ngwa eletriki na ụlọ ọrụ mmepụta ihe.A pụkwara iji hecs mee ihe dị ka ndị na-ekpo ọkụ, ndị na-ekesa na ihe mgbochi ọnụ ọgụgụ.
HPMC bụ analọgụ ethylene-acetate ọzọ, nke mejupụtara methanol, sodium hydroxide, na carbonate.Ọ nwere nnukwu viscosity, elasticity na expansibility, enwere ike iji ya dị ka nrapado, eserese, ihe nhicha na ihe mgbakwunye ink.Tụkwasị na nke ahụ, a pụkwara iji ya mee ihe maka nkwadebe kristal ma nwee nkwụsi ike nke usoro dị nro.
Hydroxyethyl cellulose HEC, dị ka a na-abụghị ionic surfactant, nwere ihe ndị a na mgbakwunye na ndim, nkwusioru, adhesion, sere n'elu, ihe nkiri e guzobere, mgbasa, mmiri njide na nchebe colloidal mmetụta:
1, hydroxyethyl cellulose HEC nwere ike igbari na mmiri ọkụ ma ọ bụ mmiri oyi, okpomọkụ dị elu ma ọ bụ esi esi adịghị eme ka ọ dị elu, nke mere na ọ nwere ọtụtụ ihe solubility na njirimara viscosity, na ihe gel na-adịghị ọkụ;
2, hydroxyethyl cellulose HEC n'onwe ya na-abụghị ionic ụdị nwere ike ibikọ ọnụ na a dịgasị iche iche nke ọzọ mmiri-soluble polymers, surfactants, salts, bụ ụdị colloidal thickener nwere elu electrolyte ngwọta;
3, hydroxyethyl cellulose HEC ikike njigide mmiri dị okpukpu abụọ karịa methyl cellulose, na nhazi nhazi;
4. Ike mgbasa nke hydroxyethyl cellulose HEC adịghị mma ma e jiri ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ma nchebe nke ike colloid siri ike.
Nzube: A na-ejikarị eme ihe dị ka onye na-emepụta ihe, onye na-ahụ maka nchebe, nrapado, stabilizer na nkwadebe nke agba latex, lacquer, ink.Ihe mgbakwunye ndị a na-eji na-egwupụta mmanụ, gels, ude, ude mmiri, ihe nchacha anya, suppositories na mbadamba nkume, nke a na-ejikwa dị ka gels hydrophilic, skeleton skeleton, nkwadebe nke skeleton kwadoro ntọhapụ, a pụkwara iji ya mee ihe dị ka ndị na-edozi nri.
