Hydroxypropyl methylcellulose (HPMC) ni ibikoresho bitandukanye byinganda zikoreshwa cyane mugukora ifu yifu yinkuta, cyane cyane mubikorwa byo murugo no hanze.
Ifu ya HPMC:
Ibisobanuro n'ibigize:
Hydroxypropyl methylcellulose, yitwa HPMC, ni selile yahinduwe ya selile ikomoka kuri selile naturel.Ihindurwamo uburyo bwo guhindura selile, imiti ya karubone nziza iboneka murukuta rwibimera.Guhindura bikubiyemo kwinjiza hydroxypropyl na methyl mumatsinda ya selile, bikavamo gushonga amazi kandi polymer nyinshi.
Imiterere yumubiri na chimique:
Gukemura: HPMC irashonga mumazi, ikora igisubizo gisobanutse kandi kitagira ibara.Ibisubizo birashobora guhinduka muguhindura urwego rwo gusimbuza (DS) mugihe cyo gukora.
Viscosity: HPMC itanga ubwiza bugenzurwa kandi buhoraho kubisubizo.Uyu mutungo ningirakamaro muburyo bwo gushiraho urukuta kuko bigira ingaruka kumikorere no kubiranga ibikoresho.
Ubushyuhe bwa Thermal: HPMC yerekana ubushyuhe bwumuriro, bivuze ko ishobora gukora gel iyo ishyushye.Uyu mutungo ufite agaciro mubikorwa bimwe na bimwe aho gelling ikenewe.
Gushyira mu bikorwa HPMC mu rukuta:
Urukuta rw'imbere:
1. Guhuza no gufatana:
HPMC yongerera imbaraga imiterere yimbere yinkuta zimbere, ikemeza neza guhuza substrate nka beto, stucco cyangwa akuma.
Imiterere ya selile ya HPMC ikora firime yoroheje hejuru, itanga umurongo ukomeye kandi urambye.
2. Gutunganya no koroshya gusaba:
Ubugenzuzi bugenzurwa na HPMC butanga uburyo bwiza bwo gukora, butuma bukoreshwa neza kandi byoroshye imbere yimbere.
Irinda kugabanuka no gutonyanga mugihe cyo kuyisaba kandi ikanemeza umwenda umwe.
3. Kubika amazi:
HPMC ikora nk'igikoresho cyo kubika amazi, ikumira amazi vuba vuba mugihe cyo gukira.Ibi bifasha kunoza hydratiya ya putty, bikavamo iterambere ryiza.
Urukuta rwo hanze:
1. Kurwanya ikirere:
HPMC yongerera ikirere guhangana n’urukuta rwo hanze kandi ikarinda ingaruka mbi z’izuba, imvura n’imihindagurikire y’ubushyuhe.
Filime ya polymer yakozwe na HPMC ikora nka bariyeri, irinda ubuhehere kwinjira no gukomeza ubusugire bwikibiriti.
2. Kurwanya ibice:
Ihinduka rya HPMC rigira uruhare mukurwanya urukuta rwinyuma.Yakira ingendo ya substrate itagize ingaruka ku busugire bwa coating.
Uyu mutungo ningirakamaro kubikorwa byo hanze byugarijwe nibidukikije.
3. Kuramba:
HPMC itezimbere muri rusange kuramba kwinyuma mu kongera imbaraga zo kurwanya abrasion, ingaruka hamwe n’imiti.
Filime ikingira yakozwe na HPMC ifasha kongera igihe cyo gutwikira kandi igabanya ibikenewe kubungabungwa kenshi.
Ibyiza byo gukoresha HPMC murukuta:
1. Ubwiza buhamye:
HPMC iremeza ko urukuta rushyizweho rwujuje ubuziranenge kandi rwujuje ubuziranenge bukenewe.
2. Kunoza imikorere:
Ubugenzuzi bugenzurwa na HPMC butanga uburyo bwiza bwo gukora, bigatuma gahunda yo gusaba ikora neza kandi ikanakoresha inshuti.
3. Kongera imbaraga:
Ibiranga ibintu bya HPMC bigira uruhare muguhuza neza, kwemeza ko putty ifata neza kuri substrate zitandukanye.
4. Guhindura byinshi:
HPMC irahuze kandi irashobora gukoreshwa muburyo butandukanye kandi irashobora guhindurwa kugirango ihuze ibyifuzo byumushinga.
mu gusoza:
Hydroxypropyl methylcellulose (HPMC) ifu ningingo yingenzi muburyo bwimbere ninyuma yo hanze.Imiterere yihariye, harimo kwikemurira ibibazo, kugenzura ubukonje hamwe nubushobozi bwo gukora firime, bituma biba byiza mukuzamura imikorere nigihe kirekire cyo gutwikisha urukuta.Byaba bikoreshwa mu nzu cyangwa hanze, inkuta zirimo HPMC zitanga ubuziranenge buhoraho, kunoza imikorere no kurinda igihe kirekire kwirinda ibidukikije.Mugihe inganda zubwubatsi zikomeje gutera imbere, uruhare rwa HPMC mugushiraho urukuta rukomeje kuba ntangarugero kugirango tugere ku ireme ryiza kandi rihamye.
