Hydroxypropyl methylcellulose, 28-30% methoxyl, 7-12% hydroxypropyl

Ibisobanuro "28-30% methoxyl" na "7-12% hydroxypropyl" bivuga urwego rwo gusimbuza muriHydroxypropyl Methylcellulose(HPMC). Izi ndangagaciro zigaragaza uburyo polymer ya cellulose yahinduwe hakoreshejwe imiti hifashishijwe amatsinda ya methoxyl na hydroxypropyl.

1. 28-30% Methoxyl:
   • Ibi bigaragaza ko, ugereranyije, 28-30% by'amatsinda ya hydroxyl y'umwimerere kuri molekile ya selulose yasimbuwe n'amatsinda ya methoxyl. Amatsinda ya methoxyl (-OCH3) ashyirwamo kugira ngo yongere ubushobozi bwo gutonyanga polymer.
2. 7-12% Hydroxypropyl:
   • Ibi bivuze ko, ugereranyije, 7-12% by'amatsinda ya hydroxyl y'umwimerere kuri molekile ya selulosi yasimbuwe n'amatsinda ya hydroxypropyl. Amatsinda ya hydroxypropyl (-OCH2CHOHCH3) ashyirwamo kugira ngo yongere ubushobozi bwo gushonga kw'amazi no guhindura indi miterere y'umubiri n'iya shimi ya polymer.

Urugero rw'isimburana rugira ingaruka ku miterere ya HPMC n'imikorere yayo mu bikorwa bitandukanye. Urugero:

• Ingano nyinshi ya methoxyl muri rusange yongera ubukana bwa polymer mu mazi, bigira ingaruka ku gushonga kwayo mu mazi no ku bindi bintu.
• Ingano nyinshi ya hydroxypropyl ishobora kongera ubushobozi bwo gushonga mu mazi no gukora filime ya HPMC.

Ibi bipimo ni ingenzi mu guhindura HPMC kugira ngo yuzuze ibisabwa byihariye mu nganda zitandukanye. Urugero, mu nganda zikora imiti, guhitamo urwego rwa HPMC rufite urwego rwihariye rwo gusimbuza bishobora kugira ingaruka ku miterere y’imiti isohoka mu miti ikoreshwa mu binini. Mu nganda z’ubwubatsi, bishobora kugira ingaruka ku miterere y’amazi n’uburyo ibikomoka kuri sima bigumana amazi.

Abakora imashini zikora ibyiciro bitandukanye bya HPMC bifite urwego rutandukanye rwo gusimbuza kugira ngo bihuze n'ibikenewe bitandukanye by'imashini zitandukanye. Mu gihe bakoresha HPMC mu mashini zikoreshwa, ni ngombwa ko abakora imashini zikoreshwa batekereza ku bipimo byihariye bya HPMC bihuye n'imiterere yifuzwa n'imikorere y'imashini zikoreshwa.
