1. Hydroxypropyl methylcellulose ni iki?
Hydroxypropyl methylcellulose (HPMC)ni uburozi butagira uburozi kandi butagira ingaruka butari ionic selulose ether, bukoreshwa cyane mubikoresho byubaka, ibiryo, ubuvuzi, kwisiga nizindi nzego. Ifite imirimo yo kubyimba, kubika amazi, gukora firime, guhuza, gusiga no guhagarika, kandi irashobora gushonga mumazi kugirango ibe igisubizo kiboneye cyangwa cyoroshye.
2. Gukoresha bisanzwe no gukoresha HPMC
Umwanya wo kubaka
HPMC ikoreshwa mubikoresho byubaka nka sima ya sima, ifu yuzuye, ifata ya tile, nibindi.:
Imikorere: Kongera imikorere yubwubatsi, kunoza gufata amazi, kongera igihe cyo gufungura, no kunoza imikorere.
Uburyo bukoreshwa:
Ongeraho muburyo bwumye-buvanze, ingano isabwa ni 0.1% ~ 0.5% ya misa ya sima cyangwa substrate;
Nyuma yo gukurura byuzuye, ongeramo amazi hanyuma ubyerekeze.
Inganda zikora ibiribwa
HPMC irashobora gukoreshwa nkibyimbye, stabilisateur na emulisiferi, kandi bikunze kuboneka mubiribwa nka ice cream, jelly, umutsima, nibindi.:
Imikorere: Kunoza uburyohe, gutuza sisitemu, no gukumira ibyiciro.
Ikoreshwa:
Kunyunyuza mumazi akonje, dosiye isabwa ihindurwa hagati ya 0.2% na 2% ukurikije ubwoko bwibiryo;
Gushyushya cyangwa gukanika imashini bishobora kwihuta.
Inganda zimiti
HPMC ikoreshwa kenshi mugutwikiriye ibinini byibiyobyabwenge, bikomeza-kurekura ibinini bya matrix cyangwa capsule shell:
Imikorere: gushiraho firime, gutinda kurekura ibiyobyabwenge, no kurinda ibikorwa byibiyobyabwenge.
Ikoreshwa:
Witegure igisubizo hamwe na concentration ya 1% kugeza 5%;
Sasa neza hejuru ya tablet kugirango ukore firime yoroheje.
Amavuta yo kwisiga
HPMCikoreshwa nkibyimbye, emulion stabilisateur cyangwa agent ikora firime, ikunze gukoreshwa mumasike yo mumaso, amavuta yo kwisiga, nibindi.:
Imikorere: Kunoza imiterere no kongera ibyiyumvo byibicuruzwa.
Ikoreshwa:
Ongeraho matrike yo kwisiga mukigereranyo hanyuma ukangure neza;
Igipimo muri rusange 0.1% kugeza 1%, gihinduwe ukurikije ibicuruzwa bisabwa.
3. Uburyo bwo gusesa HPMC
Ubushobozi bwa HPMC bugira ingaruka cyane kubushyuhe bwamazi:
Biroroshye gushonga mumazi akonje kandi birashobora gukora igisubizo kimwe;
Ntishobora gushonga mumazi ashyushye, ariko irashobora gutatana no gukora colloid nyuma yo gukonja.
Intambwe zihariye zo gusesa:
Kunyanyagiza HPMC buhoro buhoro mumazi, irinde gusuka neza kugirango wirinde guteka;
Koresha stirrer kugirango uvange neza;
Hindura igisubizo cyibisubizo bikenewe.
4. Kwirinda gukoresha HPMC
Igenzura ryimikoreshereze: Muburyo butandukanye bwo gusaba, dosiye igira ingaruka kumikorere kandi igomba gupimwa ukurikije ibikenewe.
Imiterere yububiko: Igomba kubikwa ahantu hakonje, humye, hahumeka kugirango hirindwe ubushuhe nubushyuhe bwinshi.
Kurengera ibidukikije: HPMC irashobora kwangirika kandi ntabwo yangiza ibidukikije, ariko iracyakeneye gukoreshwa muburyo busanzwe kugirango birinde imyanda.
Ikizamini cyo guhuza: Iyo wongeyeho sisitemu igoye (nk'amavuta yo kwisiga cyangwa imiti), guhuza nibindi bikoresho bigomba kugeragezwa.
5. Ibyiza bya HPMC
Ntabwo ari uburozi, bwangiza ibidukikije, umutekano mwinshi;
Guhinduranya, guhuza nibisabwa bitandukanye byo gusaba;
Guhagarara neza, birashobora kubungabunga imikorere igihe kirekire.
6. Ibibazo rusange nibisubizo
Ikibazo cya Agglomeration: Witondere inyongera yatatanye mugihe cyo kuyikoresha hanyuma ubyuke icyarimwe.
Igihe kinini cyo gusesa: Gutegura amazi ashyushye cyangwa gukanika imashini birashobora gukoreshwa kugirango byihute.
Kwangirika kw'imikorere: Witondere ibidukikije kugirango wirinde ubushuhe n'ubushyuhe.
Ukoresheje HPMC mubuhanga no gushyira mu gaciro, ibiranga imikorere yayo irashobora gukoreshwa rwose kugirango itange ibisubizo byiza cyane mubikorwa bitandukanye.
