▲Hydroxypropyl methyl selulose (HPMC)ni impumuro nziza, idafite uburyohe, ifu yera idafite uburozi. Nyuma yo gushonga byuzuye mumazi, hydroxypropyl methyl selulose izakora colloid ibonerana.
Ibikoresho by'ibanze bya hydroxypropyl methyl selulose (HPMC): ipamba itunganijwe, chloride methyl, okiside ya propylene, nibindi bikoresho fatizo, soda ya caustic, aside, toluene, isopropanol, nibindi.
Kugereranya ibyiza nibibi bya hydroxypropyl methyl selulose:
1.Hidroxypropyl methyl selulose HPMC irekuye neza kandi ifite ubwinshi buke, hamwe nubunini bwa 0.3–0.4 / ml.
HPMC yasambanijwe ifite flux nziza cyane kandi yumva iremereye, itandukanye cyane nibicuruzwa nyabyo mubigaragara.
2. Hydroxypropyl methyl selulose HPMC igisubizo cyamazi kirasobanutse, kohereza urumuri rwinshi, igipimo cyo gufata amazi> 97%.
Igisubizo cyamazi ya HPMC yanduye kirasa nkaho cyanduye, kandi igipimo cyo gufata amazi kiragoye kugera kuri 80%.
3. HPMC itanduye ntigomba kunuka ammonia, krahisi na alcool.
Ubusambanyi bwa HPMC burashobora guhumura ubwoko bwubwoko bwose, nubwo butaryoshye, buzumva buremereye.
4. Hydroxypropyl methyl selulose Ifu ya HPMC ni fibrous munsi ya microscope cyangwa ikirahure kinini.
HPMC yangiritse irashobora kugaragara nkibintu bya granulaire cyangwa kristu munsi ya microscope cyangwa ikirahure kinini.
Ni ubuhe buryo bwo kumenya ibyiza n'ibibi bya hydroxypropyl methyl selulose?
Impamyabumenyi yera
Nubwo umweru udashobora kumenya niba HPMC yoroshye gukoresha, kandi niba ibikoresho byera byongewe mugihe cyibikorwa, bizagira ingaruka kumiterere yabyo. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.
2.Ubwiza
Ubwiza bwa HPMC muri rusange bufite mesh 80 na mesh 100, kandi nibyiza, muri rusange, nibyiza.
3.Kwimura
Shyirahydroxypropyl methyl selulose (HPMC)mumazi kugirango akore colloid ibonerana, kandi urebe itumanaho ryayo. Iyo urumuri rwinshi rwohereza, nibyiza, byerekana ko muri byo harimo ibintu bike bidashonga. Ubushobozi bwimikorere ihagaritse nibyiza muri rusange nibyiza, mugihe ibya reaction ya horizontal ari bibi.
4.Umubare
Ninini nini ya rukuruzi yihariye, iremereye nibyiza. Umwihariko ni munini, muri rusange kubera ko ibiri mu itsinda rya hydroxypropyl muri yo ari byinshi, kandi ibikubiye mu itsinda rya hydroxypropyl ni byinshi, gufata amazi ni byiza.
