Ni ubuhe buryo bukoreshwa bwa HPMC?
HPMC irashobora kugabanywamo: icyiciro cyubwubatsi, urwego rwibiryo hamwe nicyiciro cyubuvuzi ukoresheje.
HPMC ikoreshwa cyane mubikoresho byubaka, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda.
Kugeza ubu, ibyiciro byinshi byubwubatsi bwo murugo, mubyiciro byubwubatsi, ingano yifu ya putty nini, hafi 90% ikoreshwa mugukora ifu yimbuto, ibisigaye bikoreshwa mugukora sima na kole.

Ibicuruzwa ako kanya, mumazi akonje bikwirakwira vuba, bizimira mumazi, muriki gihe ayo mazi nta bwenge afite, kuko HPMC ikwirakwizwa mumazi gusa, nta gushonga kwukuri. Hafi yiminota 2, ubwiza bwamazi bwiyongera buhoro buhoro, bikora colloid ibonerana. Urutonde rwagutse, mumashanyarazi ya pome na minisiteri, hamwe na kole yamazi hamwe n irangi, birashobora gukoreshwa, nta kirazira.

Ibicuruzwa bishushe bishyushye, mumazi akonje, birashobora gukwirakwira vuba mumazi ashyushye, bikabura mumazi ashyushye, mugihe ubushyuhe bugabanutse kubushyuhe runaka, ubukonje bugaragara buhoro buhoro, kugeza igihe habaye colloid ibonerana. Irashobora gukoreshwa gusa muri poro ya poro na minisiteri, mumazi ya kole hamwe n irangi, hazabaho ibintu byitsinda, ntibishobora gukoreshwa.

Nibihe bintu nyamukuru byerekana tekinike yaHPMC?
Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bahangayikishijwe nibi bipimo byombi.

Hydroxypropyl irimo byinshi, kubika amazi muri rusange nibyiza.

Viscosity, kubika amazi, isano (ariko ntabwo ari absolute) nayo nibyiza, hamwe nubwiza, muri sima ya sima koresha neza.

Nibangahe bingana kuri HPMC?
Uruhare runini rwa HPMC ni ukubika amazi, hagakurikiraho kubyimba.
Ifu yuzuye ni 100000 cps irashobora. Igihe cyose gufata amazi ari byiza, ubukonje buri hasi (70.000-80000), birashoboka kandi, byanze bikunze, ubwiza ni bunini, kugumana amazi ugereranije nibyiza, mugihe ubwiza burenze 100.000, ubwiza bufite ingaruka nke ku gufata amazi.
Ibisabwa muri MORTAR ni birebire, USHAKA RUSANGE Ibihumbi 150 gusa kuba byiza gukoresha.
Porogaramu ya kole: ikenera ibicuruzwa ako kanya, ubwiza bwinshi.
