(1) Incamake ya hydroxypropyl methylcellulose ako kanya
Hydroxypropyl methylcellulose ako kanya (HPMC) ni ether idafite ionic selulose ether yabonetse muguhindura imiti ya selile naturel kandi ifite solubile nziza nibiranga viscosity. Imiterere ya molekile yayo irimo hydroxyl, imikorerexy na hydroxypropoxy matsinda. Iri tsinda rikora ritanga imiterere yihariye yumubiri nubumashini, bigira akamaro mubikorwa bitandukanye.
(2) Imikorere ya HPMC mubikoresho byubaka
Mu murima wubwubatsi, HPMC ninyongera yingirakamaro kandi ikoreshwa cyane mubikoresho bitandukanye byubaka, nk'ibiti bifata amabati, ibiti byo kurukuta, ibyuma byumye, n'ibindi. Ibikorwa byayo byingenzi mubikoresho byubaka birimo:
1. Ingaruka mbi
HPMC irashobora kongera cyane ubwiza nuburinganire bwibikoresho byubaka. Ingaruka yabyimbye ituruka kumyanya yabyimbye mumazi hamwe numuyoboro uhuza hydrogène ya hydrogène. Ubukonje bukwiye burashobora kunoza imikorere yibikoresho mugihe cyubwubatsi kandi bikarinda ibifata kugabanuka iyo bishyizwe hejuru yubutumburuke, bityo ubwiza bwubwubatsi.
2. Ingaruka yo gufata amazi
HPMC ifite uburyo bwiza bwo gufata amazi, bushobora kugabanya gutakaza amazi mugihe cyo kubaka. Kubika amazi nikintu cyingenzi kiranga ibyuma byubaka. Cyane cyane mubikoresho bishingiye kuri sima hamwe na gypsumu, ingaruka zo gufata amazi ya HPMC zirashobora kwongerera igihe cyo gufungura ibifatika, bigatanga igihe kirekire kandi bigahinduka, bikarinda guturika hakiri kare kandi bikagabanya imbaraga.
3. Kunoza imikorere
HPMC irashobora kunoza imikorere yimikorere yubwubatsi, harimo amazi, ubwubatsi no gusibanganya. Ingaruka zayo zo gusiga zituma ibifata byoroha kuyikoresha no kuyisiba mugihe cyubwubatsi, igateza imbere ubwubatsi nuburinganire bwubuso bwubwubatsi, kandi ikemeza ingaruka zubwubatsi bwa nyuma.
4. Kongera imbaraga zo guhuza
HPMC irashobora kongera ubwuzuzanye hagati yumuti na substrate kandi igatezimbere imbaraga zo guhuza ibifatika mugukora urwego rumwe kandi rwiza. Ibi nibyingenzi muburyo butajegajega bwubaka nkurukuta hasi, kandi birashobora gukumira neza amabati, kureba amabati, nibindi bitagwa.
5. Imikorere yo kurwanya kunyerera
Mubisabwa nka tile yifata, HPMC irashobora kunoza ibikoresho byo kurwanya kunyerera. Ibi bifasha kugumisha amabati hejuru yubwubatsi buhagaze, kugabanya inshuro zo guhindura no gukora akazi, bityo bikazamura ubwiza bwubwubatsi.
(3) Porogaramu zihariye za HPMC mubikoresho bitandukanye byubaka
1. Amatafari
Mu gufatisha amabati, HPMC ntabwo igira uruhare gusa mu kubyimba no kugumana amazi, ahubwo inatezimbere imikorere yo kurwanya kunyerera yometse kuri tile, bigatuma amatafari ahagarara mugihe cyo kubaka. Imiterere yihariye ya rheologiya ituma ibifata bigumana ubwiza bukwiye mubihe bitandukanye byubwubatsi, byoroshye guhinduka no kubaka.
2. Urukuta
HPMC igira uruhare runini mu kugumana amazi no kubyimba mu rukuta, bigatuma putty ikora cyane kandi ikagira ubuso bunoze nyuma yo gukama. Kugumana amazi kwayo birashobora kugabanya gucikamo no kugabanuka kurwego rwa putty mugihe cyo kubaka, kandi bikazamura ireme ryububiko bwa nyuma.
3. Amabuye yumye
Muri minisiteri yumye, umurimo wingenzi wa HPMC ni ukugumana ubushuhe no kwirinda gutakaza amazi hakiri kare, bityo bikazamura imikorere no gufatira kuri minisiteri. Irashobora kandi guhindura ubudahangarwa bwa minisiteri kugirango ikoreshwe mubihe bitandukanye byubwubatsi, nka minisiteri yububoshyi, plaster, nibindi.
4. Kubaka kashe
HPMC ikoreshwa cyane mukubaka kashe kugirango iteze imbere kandi ikore neza ya koleoide, kugirango ibashe kuzuza ingingo mugihe cyo kuyikoresha kandi ikomeze gukomera no gukomera. Kubika amazi birashobora kandi kubuza kashe gutakaza amazi vuba kandi bikazamura ubwubatsi.
(4) Ibyiza bya HPMC mukubaka ibiti
Kurengera ibidukikije: HPMC ikomoka kuri selile naturel, ifite imiti ihamye, ntabwo irekura ibintu byangiza mugihe cyo kuyikoresha, kandi yangiza ibidukikije numubiri wumuntu.
Igihagararo: HPMC ifite imiti ihamye kandi ntishobora guhindurwa byoroshye nibidukikije nkubushyuhe na pH, kandi irashobora gukomeza imikorere yayo igihe kirekire.
Guhuza: HPMC ihujwe nibikoresho bitandukanye byubaka kandi irashobora guhuzwa neza nibikoresho nka sima, gypsumu, na minisiteri kugirango ikore imirimo yayo yo kubyimba no gufata amazi.
(5) Iterambere ry'ejo hazaza
Hamwe niterambere ryikoranabuhanga ryubwubatsi, ibyifuzo bya HPMC mukubaka ibiti ni binini. Ibishoboka byerekezo byiterambere bizaza harimo:
Gutezimbere imikorere: Kunoza imikorere ya HPMC binyuze muguhindura imiti cyangwa guhuza nibindi byongeweho kugirango uhuze ibikenerwa mubikorwa bitandukanye byubwubatsi.
Ibicuruzwa bitangiza ibidukikije: Gutezimbere ibidukikije byangiza ibidukikije kandi byangirika HPMC kugirango bigabanye ingaruka kubidukikije.
Ibikoresho byubwenge: Shakisha ikoreshwa rya HPMC mubikoresho byubwubatsi byubwenge, nkibikoresho byo kwikiza ubwabyo, ibikoresho byita ku bushyuhe, nibindi, kugirango urwego rwubwenge rwibikoresho byubaka.
Hydroxypropyl methylcellulose ako kanya, nk'inyongera y'ingenzi mu kubaka ibiti, igira uruhare runini mu kuzamura ubwiza, gufata amazi, hamwe n'ubwubatsi bw'ibiti. Ikoreshwa ryayo muri tile yometse, urukuta, urukuta rwumye nizindi mirima byazamuye ubwubatsi nubwiza. Mu bihe biri imbere, binyuze mu guhanga udushya mu ikoranabuhanga no kurushaho kumenyekanisha ibidukikije, ishyirwa mu bikorwa rya HPMC mu kubaka ibiti bizatangiza umwanya mugari w'iterambere.
