Itandukaniro riri hagati yo gusenya ako kanya kandi gahoro ka HPMC

Mugukoresha hydroxyproppopyl methyl selileHpmc, mubisanzwe dusanga ahanini biterwa nubwo ubwoko bubiri: gusenya ako kanya kandi buhoro. Reka twumve itandukaniro riri hagati yo gusenya byihuse no gusesa buhoro hakurya ya hydroxypropyl methyl selile.

Ako kanya HPMC yerekeza ku gukoresha umukozi uhuza imiti mu buryo bwo gukora, kugira ngo HPMC idatatana mu mazi akonje, ariko nta gisubizo nyacyo cyatatanye mu mazi akonje, ariko aho kuba igisubizo nyacyo, binyuze mu gukangurira imyenda, ni ukuvuga, gusesa;

Buhoro buhoro HPMC irashobora kandi kwitwa ibicuruzwa bishyushye. Iyo amazi akonje ahuye, arashobora gutatana vuba mumazi ashyushye. Mugushishikariza cyane, ubushyuhe bwimiti buzamanuka ku bushyuhe runaka. .

Dore itandukaniro riri hagati yumuti wihuse no gukemura buhoro. Niba ufite ikibazo kijyanye n'ubu bumenyi, urashobora no kutubaza.

HydroxyPropyl Methyl Cellulose HPMC yatinze guhagarika swation

Ongeraho HydroxyPropyl Methyl Cellulose muri sima itinda hydtion. None ni iki uzi ku kuntu ikora? Reka turebe HydroxyPropyl Methyl Cellulose kugirango itandure ibyuma. Ihame.

1. Ihanga rya Horsothesis

Twakoze cyane ko hydroxyPropyl methyl Methyl Methyl Methyl yatumye habaho ibitekerezo bya pore, bibangamira igipimo cya iore, bikabangamira igipimo cya ionic Nyamara, hasurwa na selile elegiteri muriki kizamini yari ifite ubushobozi bukomeye bwo gutinza sima. Kubwibyo, iki gitekerezo nticyemewe. Pourchez et al. gushidikanya kandi iyi hypothesis. Mubyukuri, igihe cya ion kwimuka cyangwa kwimuka ni bigufi cyane, biragaragara ko bidasa no gutinda kwa sima.

2. Gutesha agaciro Alkaline

Polysacchade yatesheje ubusa muburyo bwa alkaline kugirango atange Hydroxyl Imodoka ya Hydroxyl ACID zitinda kwibeshya. Kubwibyo, hatinda hydrosiyo ya hydroxyPropyl methyl Methyl irashobora guterwa no gutesha agaciro muri sima ya alkaline kugirango ice ya hydroxycar acide ya hydroxycar. Ariko, pourchez et al. Habonetse ko aba erefoni bahagaze neza mumiterere ya alkaline, yangiritse gato, kandi ibicuruzwa byangiza ntacyo byagize ingaruka mbi ku gutinda kwa sima.

3, adsorption

Adsorption irashobora kuba hydroxypropyl methyl methiose clower symetion impamvu ni uko inyongeramusaruro nyinshi zizamurirwa ku bice bya sima hamwe no gutinda kubicuruzwa bya Fodration, kugirango bitinde kuri edmetion na cumensetion ya sima. Pourchez et al. Habonetse ko erega erega yahimbyaga hejuru yibicuruzwa bya hydration nka calcium hydroxide, Csh Gel na Calcium bamanukana na hydrate, ariko ntabwo bahinduwe byoroshye na ettritete yicyiciro cya ettrike. Byongeye kandi, kubijyanye na selile ether, ubushobozi bwa adsorption ya Hec arakomeye kuruta kubyimba MC. Hasi ibiri muri hydroxyyethyl muri hec cyangwa hydroxyproppopyl muri HPMC, imbaraga za adsorproproppopy: NUBUNTU BWO KUBUNTU, Ubushobozi bwa Hydration, ubushobozi bwa calcium burakomeye kuruta uko Csh. Indi msesengura nayo yerekana ko ubushobozi bwa adsorption y'ibicuruzwa bya hydles na selile bifitanye isano no gutinda kwa sima: Adsorprite, ariko biragaragara ko uwatinze, ariko bigaragara ko umuhanga mugari afite intege nke, ariko utsindira, ariko ibi byatinze cyane. Ubugari bwa Tricalcium Selicate kandi Ibicuruzwa bya Hydration bifite adsorption ikomeye, biragaragara ko bidindiza inzira ya syration yicyiciro cya silicate, kubera ko icyatsi kibisi kiragaragara, kuko cyatinze gutoranya urugero, kubera ko ettleriptrite igaragara cyane, kuko yatinze gutoranya urugero ari hasi cyane, ariko bitinda gutoranya kwaratsindwa cyane, ariko bitinda gucibwa gucibwa na CA 2 + bikabije. Gutinda kwangiza hyderation byakomeje.

Izi ni hydroxypropyl methyl Methyl yatinze gutinda sima hafales. Turizera ko ubu bumenyi buzatuma abantu bose bumva uburyo ibicuruzwa bikora kandi bikayikoresha neza.
