HydroxyPropyl Methyl Cellulose (HPMC), izwi kandi nizina ryubucuruzi Hypromellose, ni polymer ya sinter yakomokaga kuri selile kamere. Inkomoko yambere ya selile kugirango umusaruro wa HPMC isanzwe ifu cyangwa ipamba. Igikorwa cyo gukora kirimo guhinduranya sigari binyuze kuri Guhangana, kumenyekanisha hydroxyPropyl na methyl amatsinda ya selile.

Umusaruro wa HPMC urimo intambwe nyinshi:

1. Gukuramo Cellulose:
   • Ubugari buboneka mu masoko y'ibimera, ahanini cyane ibiti cyangwa ipamba. Ubugari bwakuweho kandi busukurwa kugirango bugere kuri selile.
2. Alkalisation:
   • Umuyoboro wa selile ufatwa hamwe nigisubizo cya alkaline, mubisanzwe sodiyumu hydroxide (naoh), kugirango ukoreshe amatsinda ya hydroxyl kumunyururu wa selile.
3. Guhangana:
   • Guhanga ni intambwe yingenzi mumusaruro wa HPMC. Ubugari bwa Alkalise Byakozwe hamwe na propylene oxide (kumatsinda ya hydroxylefepyle (kumatsinda ya hydroxyPropyl) na methyl chloride (kumatsinda ya methyl) kugirango amenyekanishe amatsinda ya ether) kugirango amenyekanishe aya matsinda ya ether kuri selile.
4. Kutabogama no gukaraba:
   • Ibisubizo byahinduwe byahinduwe, ubu ni hydroxyPropyl methyl Methyl Methyl Methyl Methyl Methyl, inzira yo kutabogama kugirango ikureho alkali. Noneho yogejwe neza kugirango ikureho umwanda no mubicuruzwa.
5. Kuma no gusya:
   • Ubugari bwahinduwe bwumishijwe kugirango ukureho ubushuhe burenze kandi noneho asingi mu ifu nziza. Ingano yinshi irashobora kugenzurwa ukurikije porogaramu igenewe.

Igicuruzwa cya HPMC cyavuyemo ni ifu yera cyangwa yera ifite impamyabumenyi itandukanye ya hydroxyProppopyl na methyl gusimbuza methyl. Ibintu byihariye bya HPMC, nkibikuntu, vicosity, nibindi biranga imikorere, biterwa nurwego rwo gusimbuza no gukora ibikorwa.

Ni ngombwa kumenya ko HPMC ari igice cya kabiri, kandi mugihe gikomoka kuri selile karemano, zirimo guhindura imiti mugihe cyo gukora kugirango ugere kumiterere yifuzwa muburyo butandukanye bwinganda.
