1.. Ni ubuhe buryo hydroxypropyl methylcellse?
HydroxyPropyl Methylcellse (HPMC)ni uburozi kandi butagira ingano ntabwo ari selile ya selile, ikoreshwa cyane mubikoresho byo kubaka, ibiryo, ubuvuzi, kwisiga, kwisiga nizindi nzego. Ifite imirimo yo kwinubira, kugumana amazi, gushinga filimi, guhuza, gusiga amavuta no guhagarikwa, kandi birashobora gushonga mumazi kugirango ukore igisubizo gisobanutse cyangwa gisobanutse neza.
2. Gukoresha bisanzwe no gukoresha HPMC
Umwanya wubwubatsi
HPMC ikoreshwa mubikoresho byubaka nka cement mirtar, putty ifu, tile imeza, nibindi .:
Imikorere: Gutezimbere imikorere yubwubatsi, biteza imbere kugumana amazi, ongera umwanya ufunguye, kandi utezimbere imikorere yo guhuza.
Uburyo bwo Gukoresha:
Ongeraho kuri minisiteri yumye-bivanze, umubare usabwe ni 0.1% ~ 0.5% ya misa ya sima cyangwa sustrate;
Nyuma yo gukangura byuzuye, ongeraho amazi hanyuma ukangure.
Inganda
HPMC irashobora gukoreshwa nkababyimbye, stabilizer na emalisifier, kandi bikunze kuboneka mubiryo nka ice cream, jelly, umutsima, nibindi .:
Imikorere: Kunoza uburyohe, utera imbaraga, kandi ukabuza ibintu.
Imikoreshereze:
Gushonga mumazi akonje, dosiye isabwa yahinduwe hagati ya 0.2% na 2% ukurikije ubwoko bwibiryo;
Gushyushya cyangwa gukurura imashini birashobora kwihutisha iseswa.
Inganda za farumasi
HPMC ikunze gukoreshwa mubiyobyabwenge ibiyobyabwenge, bikomeza-kurekura tablet matrix cyangwa capsule shell:
Imikorere: Gushiraho firime, kurekurwa ibiyobyabwenge, no kurengera ibikorwa byabayobyabwenge.
Imikoreshereze:
Witegure igisubizo hamwe na 1% kugeza 5%;
Spray kuri mugitondo hejuru ya tablet kugirango ikore film yoroheje.
Kwisiga
Hpmcikoreshwa nka Thickener, Swabilizer ya Emulsiyoni cyangwa Umukozi wa firime, asanzwe akoreshwa muri masike yisura, nibindi .:c .:
Imikorere: Kunoza imiterere no kuzamura kumva ibicuruzwa.
Imikoreshereze:
Ongeraho matrix yo kwisiga ukurikije ugereranije no kubyutsa ubuntu;
Umuyoboro ni 0.1% kuri 1%, byahinduwe ukurikije ibisabwa byibicuruzwa.
3. Uburyo bwa HPMC
Kudakemurwa na HPMC bigira ingaruka ku bushyuhe bw'amazi:
Biroroshye gusezerera mumazi akonje kandi birashobora gukora igisubizo kimwe;
Ntabwo yashonga mumazi ashyushye, ariko arashobora gutatana no gukora colloid nyuma yo gukonja.
Intambwe zihariye:
Kunyanyagiza HPMC buhoro mumazi, irinde gusuka kugirango wirinde kuri caking;
Koresha umukiranutsi kugirango uvange neza;
Hindura umuti wibibazo nkuko bikenewe.
4. Ingamba zo gukoresha HPMC
Igenzura rya dosage: Mubice bitandukanye bya porogaramu, dosage igira ingaruka muburyo butaziguye kandi igomba kugeragezwa ukurikije ibikenewe.
Imiterere yububiko: Bikwiye kubikwa ahantu hakonje, k-byumye, guhumeka kugirango birinde ubuhemu nubushyuhe bwinshi.
Kurengera ibidukikije: HPMC ntabwo ari bizima kandi ntabwo yanduye ibidukikije, ariko iracyakeneye gukoreshwa muburyo busanzwe kugirango yirinde imyanda.
Ikizamini cyo guhuza: Iyo wongeyeho sisitemu igoye (nko kwisiga cyangwa imiti), guhuza nibindi bikoresho bigomba kugeragezwa.
5. Ibyiza bya HPMC
Kutagira uburozi, umutekano urwaye ibidukikije, umutekano muremure;
Guhindura, guhuza n'imiterere kubisabwa bitandukanye;
Guhagarara neza, birashobora kubungabunga imikorere igihe kirekire.
6. Ibibazo rusange nibisubizo
Ikibazo cya Agglomeration: Witondere kongeramo mugihe cyo gukoresha no kubyutsa icyarimwe.
Igihe kirekire cyo gucika intege: Amazi ashyushye yitegura cyangwa gukangurira mashini arashobora gukoreshwa mukwihutisha iseswa.
Gutesha agaciro Imikorere: Witondere ibidukikije kugirango wirinde ubuhehere nubushyuhe.
Ukoresheje HPMC mu buhanga kandi mu buryo bugaragara, ibiranga byinshi byinshi birashobora gukoreshwa byuzuye kugirango utange ibisubizo byujuje ubuziranenge kunganda zitandukanye.
