Ni irihe tandukaniro riri hagati ya HPMC na CMC?

HPMC (HydroxyPropyl Methylcellselse) na CMC (CarboxyMethyl Cellulose) byombi bikoreshwa nabi, bikoreshwa cyane mubiribwa, bikoreshwa cyane mubiribwa, imiti, kubaka nibindi.

1. Imiterere yimiti nuburyo bwo gutegura

HPMC:
Imiterere yimiti: HPMC ni igice cya kabiri cya symer-synthemer cyabonetse mukwitondera selile karemano hamwe na profloride na methyl chloride nyuma yo kuvura alkali.

Igice kinini cyubaka ni impeta ya glucose, ifitanye isano na 1,4-β-glucosidic.
Uburyo bwo Kwitegura: Icyambere, Cellulose yavuwe numuti wa hydroxide yo gukora selile ya alkali, hanyuma ubyakiriye amavuta ya methislene, hanyuma akumanura, arakaraba kandi yumye kugirango abone HPMC.

CMC:
Imiterere yimiti: CMC ni aniontic aniontic aniontive yabonetse mu gufata ikarigo hamwe na aside ya chloroacetic muburyo bwa alkaline.
Igice kinini cyubaka nacyo ni impeta ya glucose, ihujwe na 1,4-β-glucosic. Amatsinda amwe n'amwe ya hydroxy4 yasimbuwe na Carboxymethyl (-Ch₂cooh).
Uburyo bwo Gutegura: TOLLECOSY YABYE HASIUM DODROSIDE YO GUKORA ALKOULOSE, icyo gihe rero yitwara nabi

2. Imiterere yumubiri na shimi.

Kudashoboka:
HPMC: Gushonga mumazi akonje hamwe nibibinyabuzima byose, bidahwitse mumazi ashyushye. Iyo igisubizo gikonje, gel isobanutse irashobora gushingwa.
CMC: Gushonga mumazi akonje namazi ashyushye kugirango akore subcous colloidal igisubizo.

Vicosity na roologiya:
HPMC: Ifite ingaruka nziza yo gukandamiza no gushikama mu gisubizo gitangaje, kandi gifite pseudoplastique (indogobe yoroheje) imiterere y'ibyoroha.
CMC: ifite ubushyuhe bwinshi nibintu byiza byimiterere mubisubizo bitangaje, byerekana thixotropy (kubyimba iyo uhagaze, unanutse iyo uhagaze) na pseudondiki).

3. Imirima isaba

HPMC:
Inganda zibiribwa: Nkuko wirikira, stabilizer, kuzenguruka hamwe na firime byahozeho, bikoreshwa muri ice cream, ibicuruzwa byamata, nibindi.
Inganda za farumasi: zikoreshwa nka binder, zinyuranyije kandi zigenzurwa numukozi usohora umukozi wo gutegura tablet.
Ibikoresho byo kubaka: Byakoreshejwe muri sima na Gypsum ibicuruzwa byo kugumana namazi no gukorana.
Amavuta yo kwisiga hamwe nibicuruzwa byitaweho: Byakoreshejwe mu mavuta, amavuta, shampoos na gels na douctus, nibindi.

CMC:
Inganda zibiribwa: Nkuko wirikira, stabilizer na emalulsiier, ikoreshwa muri Jam, Jelly, ice cream n'ibinyobwa.
Inganda za farumasi: zikoreshwa nka binder, zitandukana kubinini bya farumasi na firime byahoze ari imipira ya farumasi.
Inganda zimpapuro: ikoreshwa nkugufite imbaraga zitose hamwe numukozi wo hejuru kugirango utezimbere imbaraga zumye no gusohora impapuro.
Inganda zimyenda: Byakoreshejwe nkumukozi wa Agent hamwe nuwangije umukozi kugirango utezimbere imbaraga na gloss yimyenda.
Inganda za Imiti ya buri munsi: ikoreshwa nka Thickener na Stabilizer kubatsinzwe, ibicuruzwa byo kwita ku ruhu.

4. Kurinda ibidukikije n'umutekano

Byombi HPMC na CMC ntabwo ari ibikoresho bya polymer kandi bidashidikanywaho bidashobora kubora imiterere yumubiri wumuntu kandi muri rusange bifatwa nkibiyobyabwenge byibiryo hamwe nibibazo bya farumasi. Zingirika byoroshye mubidukikije kandi zifite umwanda muto mubidukikije.

5. Igiciro no gutanga isoko

HPMC ikoreshwa cyane mumirima hamwe nibisabwa byimbitse bitewe nigikorwa cyo kwitegura, ugereranije nigiciro cyo hejuru cyakazi nigiciro cyinshi.

Igikorwa cyo gukora cya CMC kiroroshye, ikiguzi ni gito, igiciro ni ubukungu, kandi urwego rwo gusaba ni ubugari.

Nubwo HPMC na CMC bakomoka kuri selile, berekana ibiranga bitandukanye kandi bakoresha bitewe ninzego zabo zitandukanye, imitungo ya fiziki hamwe nimirima yo gusaba. Guhitamo aho bikomoka kuri churiolose gukoresha mubisanzwe biterwa nibisabwa byihariye byasabye hamwe nibitekerezo byubukungu.
