HPMC

Hydroxypropyl Methyl Cellulose (HPMC) ni ibikoresho byinshi bya chimique bikoreshwa cyane mubikoresho byubaka, cyane cyane mugukora no gukoresha ifu yuzuye. Ifu yuzuye ni ibikoresho bikoreshwa mukubaka ubuvuzi. Igikorwa cyacyo nyamukuru nukuzuza ubusumbane bwubuso bwurukuta no gutanga urwego rwibanze kandi rusa, rutanga urufatiro rwiza rwo gutwikira cyangwa gushushanya.

Ibintu shingiro bya HPMC

HPMC ni selile itari ionic selile yabonetse muguhindura selile. Ifite amazi meza kandi irashobora gushonga vuba mumazi akonje kugirango ibe igisubizo kiboneye cyangwa cyoroshye. HPMC irimo amatsinda ya hydroxyl na methyl muburyo bwa molekile yayo, bityo ikagira umubyimba mwiza, guhagarikwa, gutatanya, emulisifike, guhuza, gukora firime, hamwe nibikorwa birinda colloid. Mubyongeyeho, ifite kandi uburyo bwiza bwo gufata amazi no gutuza, kandi ntabwo byoroshye ingaruka zubushyuhe nimpinduka za pH.

Uruhare rwa HPMC muri putty

Umuti woguhagarika no guhagarika: HPMC irashobora kongera ubukonje bwibishishwa byoroshye, bigatuma byoroha kuyikoresha no kuyishushanya mugihe cyubwubatsi, mugihe irinze kwangirika kwimyenda niyuzuza mugihe cyo kubika no kubaka.

Igikoresho cyo kubika amazi: HPMC ifite ibintu byiza byo kubika amazi, bishobora kugabanya igihombo cyamazi mugihe cyubwubatsi, kongerera igihe cyo gufungura, no kwemeza uburinganire nuburinganire bwumuti mugihe cyumye. Ibi birashobora gukumira neza kugabanuka kumenwa murwego rwo hejuru no kuzamura ubwubatsi.

Ingaruka zo gusiga: HPMC irashobora kunoza amavuta ya putty, ikoroha mugihe cyubwubatsi, kugabanya ingorane zubwubatsi, kugabanya imirimo yabakora, no kunoza imikorere.

Binder: HPMC irashobora kongera imbaraga zo guhuza hagati ya putty na substrate, bigatuma igipande cya putty gifatanye cyane hejuru yurukuta kandi bikarinda kugwa.

Kunoza imikorere yubwubatsi: HPMC irashobora kunoza imikorere ya putty, ikoroha gukwirakwira no kugenda neza mugihe usabye no gusiba, kugabanya ibimenyetso byubwubatsi, no kwemeza ubwiza nubwiza bwurukuta.

Uburyo bwo gukoresha HPMC

Mugihe cyo kubyaza umusaruro putty, HPMC isanzwe yongerwaho kuvanga byumye muburyo bwa poro. Ingano yinyongera iratandukanye bitewe nubwoko bwa putty nibisabwa. Muri rusange, umubare wa HPMC ugenzurwa hafi 0.2% ~ 0.5% yumubare wuzuye wa putty. Kugirango tumenye neza ko HPMC ishobora kugira uruhare rwayo rwose, mubisanzwe birakenewe ko uyongeraho buhoro mugihe cyo kuvanga no gukomeza kuvangwa neza.

Ibyiza nibibi bya HPMC muri putty

Ibyiza:

Kurengera ibidukikije neza: HPMC ntabwo ari uburozi kandi ntacyo itwaye, ntabwo irimo ibyuma biremereye n’ibintu byangiza, byujuje ibyangombwa byo kurengera ibidukikije, kandi byorohereza abubatsi n’ibidukikije.

Imikorere ihamye: HPMC ifite ihinduka rikomeye ryimihindagurikire y’ibidukikije nkubushyuhe na pH, imikorere ihamye, kandi ntabwo byoroshye kwangirika.

Ikoreshwa ryagutse: HPMC ikwiranye na sisitemu zitandukanye hamwe na sisitemu yo gutwikira, kandi irashobora kuzuza ibisabwa bitandukanye byubwubatsi.

Ibibi:

Igiciro kinini: Ugereranije nibindi bikoresho gakondo, HPMC ifite igiciro cyinshi, gishobora kongera igiciro cyibicuruzwa byibicuruzwa.

Yumva neza ubwiza bw’amazi: HPMC ifite ibisabwa byinshi ku bwiza bw’amazi, kandi itandukaniro ry’amazi rishobora kugira ingaruka ku gukemura no gukora.

Porogaramu ya HPMC muri putty ifite ibyiza byingenzi. Ntabwo itezimbere gusa imikorere yubwubatsi bwa putty, ahubwo inatezimbere imiterere yumubiri na chimique ya putty. Nubwo igiciro cyacyo ari kinini, kuzamura ubuziranenge no korohereza ubwubatsi bizana bituma bikoreshwa cyane mumishinga yubwubatsi bufite ireme. Hamwe niterambere ryiterambere ryibikoresho byubwubatsi, ibyifuzo bya HPMC mubikoresho nibindi byubaka bizaba binini.
