(Hydroxypropyl) methyl selulose | CAS 9004-65-3

. Ni igice cya sintetike ya polymer ikoreshwa cyane mubikorwa bitandukanye bitewe nimiterere yihariye kandi itandukanye. Hano reba neza iyi nteruro:

Imiterere n'imiterere:
1 Imiterere: HPMC ihindurwamo binyuze mu guhindura imiti ya selile, aho methyl (-CH3) na hydroxypropyl (-CH2CHOHCH3) byinjizwa mumugongo wa selile.
2 Impamyabumenyi yo Gusimburana (DS): Urwego rwo gusimbuza bivuga impuzandengo y'amatsinda asimburana kuri glucose igice mumurongo wa selile. Igena imiterere ya HPMC, nk'ububasha, ubwiza, hamwe n'ubushobozi bwo gukora film.
3 Ibyiza: HPMC yerekana ibintu nko kubyimba, kubika amazi, gukora firime, nibikorwa byubuso. Imiterere irashobora guhindurwa mugucunga DS mugihe cya synthesis.

Umusaruro:
1.Isoko rya Cellulose: Cellulose, ibikoresho by'ibanze bya HPMC, biva mu masoko ashobora kuvugururwa nk'ibiti by'ipamba cyangwa ipamba.
Etherification: Cellulose ikorerwa etherification, aho ikorerwa hamwe na okiside ya propylene kugirango itangize amatsinda ya hydroxypropyl hanyuma hamwe na methyl chloride kugirango yongere amatsinda ya methyl.
2.Purification: selile yahinduwe isukurwa kugirango ikureho umwanda nibicuruzwa, bivamo ibicuruzwa bya nyuma bya HPMC.
Porogaramu:
3.Inganda zubaka: HPMC ikoreshwa cyane mubikoresho byubwubatsi nka minisiteri ishingiye kuri sima, plaster, hamwe nudukaratasi twa tile kugirango tunoze imikorere, gufata amazi, no gufatira hamwe.
4.Imiti: Ikora nka binder, ikabyimbye, firime yahoze, hamwe na stabilisateur muburyo bwa farumasi harimo ibinini, capsules, ibisubizo byamaso, hamwe na cream yibanze.
5.Inganda zikora ibiryo: HPMC ikora nkibibyibushye, stabilisateur, na emulisiferi mubicuruzwa bitandukanye byibiribwa nka sosi, imyambarire, ice cream, nibicuruzwa bitetse.
6.Amavuta yo kwisiga no kwita ku muntu ku giti cye: Mu kwisiga no kwita ku muntu ku giti cye, HPMC ikoreshwa nk'umubyimba, uhagarika ibintu, filime yahoze, hamwe n’amazi meza mu mavuta, amavuta yo kwisiga, shampo, na geles.
7.Irangi hamwe na Coatings: Yongera ububobere, kwihanganira sag, hamwe nuburyo bwo gukora firime yibiranga bishingiye kumazi, ibifatika, hamwe nigitambaro.
Umwanzuro:
(Hydroxypropyl) methyl selulose, hamwe nuburyo butandukanye bwo gukoresha hamwe nibyiza, nibintu byingenzi mubicuruzwa byinshi byinganda nubucuruzi. Uruhare rwayo mu kuzamura imikorere, ituze, n'imikorere yuburyo butandukanye bituma iba ingenzi mumirenge myinshi. Mugihe inganda zikomeje guhanga udushya, icyifuzo cya HPMC giteganijwe gukomeza, bigatuma iterambere ryiyongera muburyo bwo kubyaza umusaruro no kubishyira mu bikorwa.
