HPMC cyangwa hydroxypropyl methylcellulose ni uruganda rukunze gukoreshwa mu nganda zitandukanye zirimo imiti, amavuta yo kwisiga nubwubatsi.Hano hari ibibazo bikunze kubazwa kuri HPMC:
Hypromellose ni iki?
HPMC ni polymer yubukorikori ikozwe muri selile, ibintu bisanzwe biboneka mubihingwa.Ikozwe muburyo bwa chimique ihindura selile hamwe na methyl na hydroxypropyl matsinda kugirango ikore ifu yamazi.
HPMC ikoreshwa iki?
HPMC ifite byinshi ikoresha mubikorwa bitandukanye.Mu nganda zimiti, ikoreshwa nka binder, umubyimba na emulisiferi kubinini, capsules namavuta.Mu nganda zo kwisiga, ikoreshwa nkibyimbye, emulisiferi na stabilisateur mu mavuta, amavuta yo kwisiga no kwisiga.Mu nganda zubaka, ikoreshwa nkibikoresho, ibyimbye kandi bigumana amazi muri sima na minisiteri.
HPMCs ifite umutekano?
HPMC muri rusange ifatwa nkumutekano kandi idafite uburozi.Ikoreshwa cyane mubikorwa bya farumasi no kwisiga aho umutekano nubuziranenge bifite akamaro kanini.Nyamara, kimwe n’imiti iyo ari yo yose, ni ngombwa gufata neza HPMC no gukurikiza ingamba zikwiye z'umutekano.
HPMC irashobora kubora?
HPMC irashobora kwangirika kandi irashobora gusenywa nibikorwa bisanzwe mugihe.Nyamara, igipimo cyibinyabuzima biterwa nibintu bitandukanye nkubushyuhe, ubushuhe ndetse no kubaho kwa mikorobe.
HPMC irashobora gukoreshwa mubiryo?
HPMC ntabwo yemerewe gukoreshwa mu biribwa mu bihugu bimwe na bimwe, harimo na Amerika.Icyakora, byemewe nk'inyongeramusaruro mu bindi bihugu nk'Ubuyapani n'Ubushinwa.Ikoreshwa nkibyimbye na stabilisateur mubiribwa bimwe na bimwe, nka ice cream nibicuruzwa bitetse.
HPMC ikorwa ite?
HPMC ikorwa no guhindura imiti ya selile, ibintu bisanzwe biboneka mu bimera.Cellulose ibanza kuvurwa nigisubizo cya alkaline kugirango ikureho umwanda kandi ikore neza.Hanyuma ikora hamwe nuruvange rwa methyl chloride na okiside ya propylene kugirango ikore HPMC.
Ni ibihe byiciro bitandukanye bya HPMC?
Hano hari amanota menshi ya HPMC, buri kimwe gifite imitungo itandukanye.Impamyabumenyi zishingiye ku bintu nk'uburemere bwa molekile, urugero rwo gusimburwa, n'ubushyuhe bwa gelation.Ibyiciro bitandukanye bya HPMC bikoreshwa mubikorwa bitandukanye mubikorwa bitandukanye.
HPMC irashobora kuvangwa nindi miti?
HPMC irashobora kuvangwa nindi miti kugirango itange ibintu bitandukanye nibiranga.Bikunze guhuzwa nizindi polymers nka polyvinylpyrrolidone (PVP) na polyethylene glycol (PEG) kugirango izamure imitekerereze yayo.
HPMC ibitswe ite?
HPMC igomba kubikwa ahantu hakonje, humye kure yubushyuhe nizuba ryizuba.Igomba kubikwa mu kintu cyumuyaga kugirango wirinde kwanduza.
Ni izihe nyungu zo gukoresha HPMC?
Ibyiza byo gukoresha HPMC harimo guhinduka kwinshi, gukemura amazi, hamwe na biodegradability.Ntabwo kandi ari uburozi, butajegajega, kandi burahujwe nindi miti myinshi.Muguhindura urwego rwo gusimbuza nuburemere bwa molekuline, imiterere yarwo irashobora guhindurwa byoroshye, bigatuma ikwirakwizwa mubikorwa bitandukanye.
