Hydroxypropyl Methylcellulose

HydroxypropylMethylcellulose (HPMC) cyangwa hypromelloseni ikintu gikomoka kus ya selulose ya Methyl eteri. Niumweru cyangwa umweru udasa n'umweru cyangwa uduce dutoeteri ya seluloseifu. Ubu ni yo selulose eteri hamwe n'imikorere myiza cyane ku isi, ihuza ubunini, guhagarika, gukwirakwiza, gutemba no gushimangira. Hydroxypropyl methyl cellulose (HPMC) Ntirigira uburozi, ryoroshye gukoresha, kandi ryoroshye gushonga mu mazi. Ni polyanion iri mu gisubizo cy'amazi kandi ifite imiterere yihariye. Imikorere yihariye ni nkuko bigaragara hano hasi:

Ibisobanuro by'umubiri n'imiti

HPMC yo mu rwego rw'ubwubatsi

HPMC yo mu rwego rwo kwisiga

HPMC yo mu rwego rwa Ceramic

HPMC yo mu rwego rwo hejuru rw'ubwiza

HPMC yo mu rwego rw'imiti

HPMC yo mu rwego rwa PVC

HPMC yo mu rwego rw'ibiribwa

Ibiranga:

1. Gushonga: Irashongesha cyane muri etanoli, eteri na asetone, kandi ishongesha mu gisubizo cya kolloidal gisobanutse cyangwa gishyushye gato mu mazi akonje. Ishobora gushongesha mu bintu bimwe na bimwe by’umwimerere, kandi ishobora no gushongesha mu kintu kivanze n’ibintu by’umwimerere bivangwa n’amazi.

2. Ubudahangarwa bw'umunyu: Irahindagurika mu bisubizo by'amazi iyo hari imyunyu y'icyuma cyangwa electrolyte organic.

3. Ibikorwa byo hejuru: bishobora gukoreshwa nk'igikingira cya koloidi, emulsifier na dispersant.

4. PH-ihamye: Agaciro ka PH gahagaze neza mu rugero ruri hagati ya 3.0 ~ 11.0. Ubushyuhe bw'amazi ntibugira ingaruka cyane ku aside cyangwa alkali.

Inzira y'imiterere ya molekile:

Imikoreshereze ya HPMC:

Hydroxypropyl methylcellulose(HPMC) ishobora gukoreshwa nk'ikintu gitera imbaraga, gikwirakwiza, gitera imbaraga, n'ikintu gitera filime gukora, n'ibindi.UbwubatsiIcyiciro HPMC ibicuruzwa bishobora gukoreshwa mu bintu bya buri munsi birimo imiti, ibikoresho by'ikoranabuhanga, resins zikoze mu nganda, ubwubatsi n'amabara, urwego rw'imiti HPMC ishobora gukoreshwa murigutwikira ibinini, n'ibindi, hamwe n'urwego rw'ibiribwa HPMC ishobora gukoreshwa nk'inyongeramusaruro zitandukanye ku biribwa.

Ubuyobozi bwa HPMCAmabwiriza:

1. Uburyo bwo gukoresha amazi ashyushye: Shyiramo 1/3 cyangwa 2/3 by'amazi mu gikoresho hanyuma ushyushye kugeza kuri dogere 80. Hydroxypropyl methyl cellulose y'ibanze(HPMC) Bishobora gukwirakwizwa mu mazi ashyushye ku buryo bungana, hanyuma ukongeramo andi mazi akonje. Mu mazi ashyushye, shyiramo amazi akonje nyuma yo kuyavanga.

2. Uburyo bwo kuvanga ifu: kuvanga hydroxypropyl methyl cellulose(HPMC) ifu irimo ibindi bintu byinshi by'ifu, uyinyanyagize neza uvanga byumye, hanyuma ushyiremo amazi kugira ngo uyishongeshe.

3. Uburyo bwo kunywesha ibinyabutabire by’umwimerere: banza unyanyagize cyangwa unyweshe hydroxypropyl methyl cellulose (HPMC) hamwe n'umushongi w'ibinyabuzima, hanyuma ukongeramo amazi kugira ngo ubishongeshe.
