Hydroxypropyl methyl cellulose HPMC ni iki?

HPMC hydroxypropyl methyl celluloseuruganda rukora ibicuruzwa bisohoka mu mahanga
Ni iyihe mikoreshereze nyamukuru ya HPMC?
HPMC ishobora kugabanywamo: urwego rw'ubwubatsi, urwego rw'ibiribwa n'urwego rw'ubuvuzi hakurikijwe ikoreshwa.
HPMC ikoreshwa cyane mu bikoresho by'ubwubatsi, gusiga irangi, resine zikoze mu nganda, ibumba, ubuvuzi, ibiribwa, imyenda, ubuhinzi, amavuta yo kwisiga, itabi n'izindi nganda.
Kuri ubu, igice kinini cy’icyiciro cy’ubwubatsi bwo mu rugo, mu cyiciro cy’ubwubatsi, igipimo cy’ifu ya putty ni kinini, hafi 90% ikoreshwa mu gukora ifu ya putty, igisigaye gikoreshwa mu gukora sima na kole.

Ni ibihe bikoresho by'ingenzi bya HPMC?
Ibikoresho by'ingenzi bya HPMC: ipamba itunganyijwe, chloromethane, propylene oxide. Ibindi bikoresho by'ibanze ni, ibinini bya alkali, aside, toluene, isopropanol n'ibindi.

- HPMC igabanyijemo amoko menshi, ni iyihe tandukaniro mu mikoreshereze?
HPMC ishobora kugabanywamo ubwoko bushongesha vuba n'ubwoko bushongesha mu bushyuhe.

Ibikoresho byihuse, mu mazi akonje byahitaga bikwirakwira vuba, bishira mu mazi, muri iki gihe amazi nta ruhushya agira, kuko HPMC ikwirakwira gusa mu mazi, nta gushonga nyakuri. Hafi iminota 2, uruhushya rw'amazi ruriyongera buhoro buhoro, rugakora colloid ibonerana. Uburyo bwinshi bwo gukoresha, mu ifu ya putty na mortier, hamwe na kole y'amazi n'irangi, birashobora gukoreshwa, nta kirazira.

Ibikoresho bishyushye bishongeshwa, mu mazi akonje, bishobora gukwirakwizwa vuba mu mazi ashyushye, bigashira mu mazi ashyushye, iyo ubushyuhe bugabanutse bukagera ku bushyuhe runaka, ubushyuhe bugenda bugaragara buhoro buhoro, kugeza igihe habayeho koloyide ibonerana. Bishobora gukoreshwa gusa mu ifu ya putty na mortier, mu kole y'amazi n'irangi, hazabaho ikintu cy'itsinda, ntigishobora gukoreshwa.

Ni ibihe bimenyetso by'ingenzi by'ikoranabuhangaHPMC?
Ingano ya Hydroxypropyl n'ubukana bwayo, abakoresha benshi bahangayikishijwe n'ibi bipimo bibiri.

Ingano ya Hydroxypropyl iri hejuru, muri rusange amazi agumana neza.

Ubucucike, kubika amazi, ubwiza (ariko atari burundu) nabyo ni byiza, kandi ubucucike, muri sima ya sima ni byiza gukoresha bimwe.

Ni ubunini bungana iki bukwiriye HPMC?
Uruhare rw'ingenzi rwa HPMC ni ukubungabunga amazi, hagakurikiraho kwiyongera.
Ifu ya putty muri rusange ishobora kuba 100000 cps. Igihe cyose amazi ashobora kugumana neza, ubukana buke (70.000-80000), birashoboka kandi, birumvikana ko ubukana buke, ubukana buke bw'amazi buba bwiza kurushaho, iyo ubukana burenze 100.000, ubukana buke ntacyo buhindura ku bukana bw'amazi.
Igisabwa muri MOTAR ni kirekire, muri rusange ushaka ibihumbi 150 kugira ngo ube mwiza wo gukoresha.
Gukoresha kole: hakenewe ibintu byihuse, ubushyuhe bwinshi.
