1. Iipropati ze-hydroxyethyl cellulose
Le mveliso imhlophe okanye imnyama tyheli ayinavumba kwaye kulula ukuhamba ngumgubo, i-40 mesh sieve rate ≥99%; ubushushu bokuthambisa: 135-140 ° C; ukuxinana okubonakalayo: 0.35-0.61g / ml; iqondo lokushisa lokubola: 205-210 ° C; ukutshisa isantya Kancinci; iqondo lobushushu elilinganayo: 23°C; I-6% kwi-50%rh, i-29% kwi-84%rh.
Iyanyibilika kumanzi abandayo kunye nakumanzi ashushu, kwaye ayinyibiliki ngokubanzi kwizinyibilikisi ezininzi zezinto eziphilayo. I-viscosity iyatshintsha kancinci kuluhlu lwexabiso le-PH 2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu.
2. Iimpawu ezibalulekileyo
Njengomntu osebenza nge-non-ionic,i-hydroxyethyl celluloseinezi mpawu zilandelayo ukongeza ukujiya, ukuxhoma, ukubopha, ukudada, ukwenza ifilim, ukusasaza, ukugcinwa kwamanzi kunye nokubonelela nge-colloid ekhuselayo:
1. I-HEC iyancibilika emanzini atshisayo okanye kumanzi abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, okwenza kube neentlobo ezininzi ze-solubility, iimpawu ze-viscosity kunye ne-gelation engeyona i-thermal.
2. Ayina-ionic kwaye inokuhlalisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, kunye neetyuwa. Yinto egqwesileyo ye-colloidal thickener yezisombululo eziphezulu ze-electrolyte.
3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, i-HEC inamandla okusasaza kakhulu, kodwa amandla anamandla okukhusela i-colloid.
3. Ukusetyenziswa kwe-hydroxyethyl cellulose
Ngokuqhelekileyo zisetyenziswa njengezinto ezityebileyo, izinto ezikhuselayo, izinto zokuncamathelisa, izizinzi kunye nezongezelelo zokulungiselela i-emulsions, iijeli, amafutha okuthambisa, izinto zokuthambisa, izicoci zamehlo, ii-suppositories kunye neetafile, kwaye zikwasetyenziswa njengejeli ze-hydrophilic, izixhobo zamathambo, Ingasetyenziselwa ukulungisa i-matrix- uhlobo oluzinzileyo lwamalungiselelo okukhululwa, kwaye lunokusetyenziswa njengesizinzisi ekutyeni.
