1. Izakhiwo ze-hydroxyethyl cellulose
Lo mkhiqizo umhlophe noma uphuzi ngokukhanyayo awunaphunga futhi ugeleza kalula impushana, isilinganiso sesefo esingu-40 semesh ≥99%;izinga lokushisa elithambile: 135-140 ° C;ukuminyana okubonakalayo: 0.35-0.61g/ml;izinga lokushisa lokubola: 205-210 ° C;isivinini esivuthayo Kancane;izinga lokushisa elilinganayo: 23°C;6% ngo-50%rh, 29% at 84%rh.
Iyancibilika kuwo womabili amanzi abandayo nasemanzini ashisayo, futhi ngokuvamile ayincibiliki kuzincibilikisi eziningi eziphilayo.I-viscosity ishintsha kancane kububanzi bevelu engu-PH 2-12, kodwa i-viscosity yehla ngale kwalolu bubanzi.
2. Izakhiwo ezibalulekile
Njengomuntu osebenza ngaphansi kwe-non-ionic,i-hydroxyethyl celluloseinalezi zakhiwo ezilandelayo ngaphezu kokujiya, ukumisa okwesikhashana, ukubopha, ukuntanta, ukwenza ifilimu, ukuhlakazeka, ukugcinwa kwamanzi nokuhlinzeka nge-colloid evikelayo:
1. I-HEC iyancibilika emanzini ashisayo noma emanzini abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, okwenza ibe nohlu olubanzi lokuncibilika, izici ze-viscosity kanye ne-gelation engashisi.
2. Ayiyona i-ionic futhi ingahlala nohlu olubanzi lwama-polymers ancibilika emanzini, ama-surfactants, nosawoti.Kuyi-thickener enhle kakhulu ye-colloidal yezixazululo ze-electrolyte zokugxila okuphezulu.
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, i-HEC inekhono elibi kakhulu lokuhlakaza, kodwa ikhono eliqinile le-colloid lokuvikela.
3. Ukusetshenziswa kwe-hydroxyethyl cellulose
Imvamisa isetshenziswa njengama-thickeners, ama-ejenti okuzivikela, ama-adhesives, stabilizers kanye nezithasiselo zokulungiselela ama-emulsions, ama-jellies, amafutha okugcoba, ama-lotions, ama-eye cleansers, ama-suppositories namaphilisi, futhi asetshenziswe njengama-gel e-hydrophilic, izinto zamathambo, Ingasetshenziswa ukulungisa i-matrix- thayipha amalungiselelo okukhululwa okuqhubekayo, futhi angasetshenziswa njengesiqinisi ekudleni.
