HydroxyPropyl Methylcellse (HPMC)Nibintu byingenzi byo kubaka, byakoreshwaga cyane muri sima, peteroli yumye, aho bihurira hamwe nizindi nzego. HPMC igira uruhare runini mumasuka ya minisiteri, kandi irashobora kunoza imikorere ibikorwa, amazi, gupfuka no kurwanya minisiteri. By'umwihariko mubwubatsi bugezweho, bigira uruhare rudakosowe mugutezimbere ubuziranenge ningaruka zubwubatsi.
1. Ibiranga ishingiro rya HPMC
HPMC ni kogo ka selile zahinduwe na chimielese, hamwe n'amazi meza, gusohora no kubyimba. Amaganya ya SporkenthPMC M molekile zirimo amatsinda abiri, hydroxypropyl na methyl, bituma biranga imiterere yo guhuza hydrophilitir na hydrophobicity, kandi birashobora kugira uruhare neza mubihe bitandukanye. Imikorere mibi yacyo ikubiyemo kubyimba, kugumana amazi, kuzamura imitekerereze no guhindura minisiteri, nibindi.
2. Ibisobanuro n'akamaro ko kugumana amazi
Kugumana amazi kwa minisiteri bivuga ubushobozi bwa minisiteri kugirango bagumane amazi mugihe cyubwubatsi. Gutakaza amazi muri minisiteri bigira ingaruka muburyo bukomeye, imbaraga nibikorwa byanyuma. Niba amazi ashize vuba, sima nibindi bikoresho bishimwa muri minisiteri ntibizabona umwanya uhagije wo kwitwara ku mashanyarazi, bikaviramo imbaraga zidahagije hamwe nimbaraga zidahagije. Kubwibyo, kugumana amazi meza nurufunguzo rwo kwemeza ireme rya minisiteri.
3. Ingaruka za HPMC kuri gereza ya mirtar
Ongeraho HPMC ya MPMC irashobora kunoza cyane kongera kugumana amazi, bigaragarira mu buryo bugaragara mu buryo bukurikira:
(1) Kunoza ubushobozi bwo kugumana amazi ya minisiteri
HPMC irashobora gushinga imiterere ya hydrogel muri minisiteri, ishobora gukuramo no kugumana amazi menshi, bityo akatinda guhumeka amazi. Cyane cyane iyo wubaka mubushyuhe bwo hejuru cyangwa ibidukikije byumye, kugumana amazi ya HPMC bigira uruhare runini. Mugutezimbere gusubizwamo amazi, HPMC irashobora kwemeza ko amazi yo muri Mrista ashobora kugira uruhare rugaragara mu guhindura imitekerereze kandi anoze imbaraga za minisiteri.
(2) Gutezimbere amazi n'imyitwarire ya minisiteri
Mugihe cyubwubatsi, buntu bukeneye gukomeza amazi runaka yorohereza imikorere yabakozi bubaka. Ihagarikwa ry'amazi ridashobora gutinda neza umuvuduko ukabije wa minisiteri, bigatuma abantu benshi kandi byoroshye abakozi bubaka gukora ibikorwa nko gusiga no gusiba. Byongeye kandi, HPMC irashobora kandi kuzamura virusi ya minisiteri no gukumira gutandukana cyangwa kwikuramo, bityo bikabungabunga uburinganire bwabwo.
(3) kubuza ubutaka buciriritse
HPMC ibangamiye imurika rya minisiteri, irashobora kugabanya ibintu byihuse amazi ya minisiteri no kugabanya ibyago byo guca. Cyane cyane mubidukikije nubushyuhe bwinshi cyangwa ubuhehere buke, amazi yihuta arashobora gutera byoroshye ibice kuri minisiteri. HPMC ifasha kugenzura impirimbanyi za minisiteri igabanya kugabanya igihombo cyamazi, gukomeza ubusugire bwa minisiteri no kwirinda gushinja.
(4) Kurengera igihe cya minisiteri
Igihe cyo gufungura cya minisiteri bivuga igihe minisiteri kirashobora gukoreshwa mugihe cyubwubatsi. Bigufi cyane umwanya ufunguye bizagira ingaruka kumikorere yubwubatsi. Ongeraho HPMC irashobora kurangira neza igihe cya minisiteri, guha abakozi bubwubatsi umwanya wo gukora ibikorwa nko gusiba no gusiga. Cyane cyane mubidukikije bigoye, kuragira igihe birashobora kwemeza ko adhesion hamwe na minisiteri ya minisiteri.
4. Uburyo bwa HPMC igira ingaruka kumazi ya mirtar
Uburyo bukuru bwa HPMC mu kunoza amazi ya minisiteri ni ibi bikurikira:
(1) Hydration hamwe nuburyo bukunda
Molekile ya HPMC irimo umubare munini wa hydrophilic ya hydroprixy (-Oh) na hydroxyProppoppopyl (-ch2oh) amatsinda, ashobora gukora hydrogen hamwe na molekile yamazi. Byongeye kandi, HPMC ifite imiterere nini ya molekelar kandi irashobora gukora imiterere yimiterere itatu muri minisiteri, ishobora gufata no kugumana amazi kandi ikatinda ku giciro cyo guhumeka amazi.
(2) Kongera ubudahuza na virusi ya minisiteri
Iyo purpontl®hpmc yongewe kuri minisiteri nkuwijimye, bizakongeramo cyane ubudabubasha no gukomera kwa minisiteri, bigatuma minisiteri ihamye kandi ikagabanya igihombo cyamazi. Cyane cyane mubidukikije byubaka, ingaruka za HPMC zifasha kunoza imikorere ya mortar.
(3) Kunoza ihungabana ryububiko bwa minisiteri
HPMC irashobora kuzamura ubumwe bwa minisiteri no kunoza imitunganyirize ya minisiteri binyuze mumikoranire yayo. Uku gutuma uburuhukiro bwa minisiteri bugomba kubungabungwa hagati yimyanyabumenyi igihe kirekire, bityo tukemeza ko reaction yuzuye kandi amazi no kongera imbaraga za minisiteri.
5. Ingaruka za HPMC muburyo bufatika
Mubyiciro bifatika,HpmcUbusanzwe ikoreshwa hamwe nizindi nguzanyo (nka plastiamizers, ipasayi, nibindi) kugirango ugere ku mikorere myiza ya minisiteri. Binyuze mu bipimo bifatika, HPMC irashobora gukina inshingano zitandukanye muburyo butandukanye bwa minisiteri. Kurugero, muri sima isanzwe ya sima, minisiteri yo gucika intege, pertar yumye, nibindi, irashobora kunoza neza ko kugumana amazi hamwe nibindi bintu bya minisiteri.
Uruhare rwa HPMC muri minisiteri ntirushobora gukemurwa. Bikaba biteza imbere ireme no gukoresha ingaruka za minisiteri mugutezimbere ihohoterwa rya minisiteri, tugura umwanya ufunguye, no kunoza imikorere yubwubatsi. Mu kubaka ubuki, hamwe no kwiyongera kwikoranabuhanga ryubwubatsi no kunoza imikorere yimikorere ya minisiteri, HPMC, nkurufunguzo rwingenzi, rufite uruhare rukomeye.
