Ni ubuhe bushyuhe HPMC iza?

Hydroxypropyl methylcellulose (HPMC) ni polymer itandukanye isanga ikoreshwa cyane mubikorwa bitandukanye birimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi. Imwe mumiterere yihariye nubushobozi bwayo bwo gukora gele mubihe byihariye. Gusobanukirwa nubushyuhe bwa gelation ya HPMC ningirakamaro mugutezimbere imikoreshereze yayo mubikorwa bitandukanye.

Intangiriro kuri HPMC:
Hydroxypropyl methylcellulose (HPMC) ni igice cya sintetike, inert, viscoelastic polymer ikomoka kuri selile. Bikunze gukoreshwa nkibibyimbye, stabilisateur, emulisiferi, na firime byahoze bitewe nuburyo bwiza bwo gukora firime nubushobozi bwo guhindura imvugo ya sisitemu y'amazi. HPMC irashobora gushonga mumazi akonje, kandi igisubizo cyacyo cyijimye biterwa nibintu nkuburemere bwa molekile, urugero rwo gusimbuza, hamwe no kwibanda.

Uburyo bwa Gelation:
Gelation bivuga inzira igisubizo gihinduka gel, cyerekana imyitwarire imeze nkubushobozi bwo kugumana imiterere yayo. Kubireba HPMC, gelation mubisanzwe ibaho binyuze muburyo buterwa nubushyuhe cyangwa hiyongereyeho izindi miti nkumunyu.

Ibintu bigira ingaruka kuri gelation:
Kwishyira hamwe kwa HPMC: Ubushuhe bwinshi bwa HPMC muri rusange butera kwihuta cyane kubera kwiyongera kwa polymer-polymer.

Uburemere bwa molekuline: Uburemere buke bwa molekuline HPMC polymers ikunda gukora gele byoroshye bitewe no kwiyongera kwinshi no guhuza imiyoboro.

Impamyabumenyi yo gusimbuza: Urwego rwo gusimbuza, rwerekana urugero rwa hydroxypropyl na methyl yo gusimbuza umugongo wa selile, bigira ingaruka ku bushyuhe bwa gelation. Impamyabumenyi yo hejuru yo gusimbuza irashobora kugabanya ubushyuhe bwa gelation.

Kubaho k'umunyu: Umunyu umwe, nka chloride ya alkali ya chloride, urashobora guteza imbere gelation muguhuza iminyururu ya polymer.

Ubushyuhe: Ubushyuhe bugira uruhare runini muri gelation. Mugihe ubushyuhe bwiyongereye, iminyururu ya polymer yunguka imbaraga za kinetic, ikorohereza molekuline ihindagurika ikenewe kugirango gel.

Ubushyuhe bwa Gelation ya HPMC:
Ubushyuhe bwa gelation ya HPMC burashobora gutandukana bitewe nibintu byinshi byavuzwe mbere. Muri rusange, HPMC geles ku bushyuhe buri hejuru yubushyuhe bwayo, ubusanzwe iri hagati ya 50 ° C na 90 ° C. Nyamara, uru rutonde rushobora gutandukana cyane bitewe nurwego rwihariye rwa HPMC, ubunini bwarwo, uburemere bwa molekile, nibindi bintu byerekana.

Porogaramu ya HPMC Gels:
Imiti ya farumasi: geles ya HPMC ikoreshwa cyane muburyo bwa farumasi kugirango irekurwe imiti igenzurwa, ikoreshwa ryibanze, kandi nkibihindura viscosity muburyo bwa dosiye.

Inganda zikora ibiribwa: Mu nganda z’ibiribwa, geles ya HPMC ikoreshwa nkibibyimbye, stabilisateur, hamwe na gelling mu bicuruzwa bitandukanye nka sosi, deserte, n’ibikomoka ku mata.

Ubwubatsi: geles ya HPMC isanga ikoreshwa mubikoresho byubwubatsi nka minisiteri ya sima, aho ikora nkibikoresho byo kubika amazi, kunoza imikorere no gufatira hamwe.

Amavuta yo kwisiga: geles ya HPMC yinjizwa muburyo bwo kwisiga nka cream, amavuta yo kwisiga, hamwe nibicuruzwa byogosha umusatsi kugirango bibyibushye kandi bihamye.

ubushyuhe bwa gelation ya HPMC biterwa nibintu bitandukanye birimo kwibanda, uburemere bwa molekile, urugero rwo gusimburwa, no kuba hari inyongeramusaruro nkumunyu. Mugihe ubushyuhe bwa gelation mubusanzwe buri hagati ya 50 ° C kugeza 90 ° C, burashobora gutandukana cyane ukurikije ibisabwa byihariye. Gusobanukirwa imyitwarire ya HPMC ningirakamaro kugirango ikoreshwe neza muburyo butandukanye mu miti yimiti, ibiryo, ubwubatsi, n’amavuta yo kwisiga. Ubundi bushakashatsi kubintu bigira ingaruka kumyuka ya HPMC burashobora kuganisha kumajyambere yimikorere ishimishije hamwe nibisobanuro bishya kuri iyi polymer itandukanye.
