▲Hydroxypropyl methyl cellulose (hpmc)ndi ufa wopanda mafuta, wopanda mphamvu, wopanda poizoni. Mukasungunuka kwathunthu m'madzi, hydroxypropyl methy cellulose imapanga cololous yama viscous.
▲ zida zazikulu za hydroxypropyl methy cellose (hpmc): HPMC), ma prostyl chloride, ma propropanol, isoppanol, eyporpanol, eyporpanol, eyporpanol, eyporol.
Kuyerekeza zabwino ndi zovuta za hydroxypropyl methyl cellulose:
1.Pop hydroxypropyl me cellulose HPMC imamasulidwa mowoneka ndipo ili ndi kachulukidwe kakang'ono kwambiri, ndi sikelo ya 0,3-0.4 / Ml.
HPMC yoyesedwa imakhala ndi madzi abwino ndipo amamva kulemera, komwe kumakhala kosiyana kwambiri ndi chinthu chenicheni chowoneka bwino.
2.Pop hydropypyl methy cellulose HPMC Aquious ndi yomveka bwino, yopepuka kwambiri, kusunga madzi osunga, 97%.
HPMC yovuta yothetsera vutoli ndi yonyansa, ndipo kuchuluka kwa madzi ndizovuta kufikira 80%.
3.Pakula hpmc sayenera kununkhira kwa ammonia, wowuma ndi mowa.
HPMC yoyesedwa imatha kununkhira mitundu yonse ya zonunkhira, ngakhale zitakhala zopweteka, zimamveka bwino.
4.Pop hydropypyl methl cellulose hpmc ufa ndi fibrous pansi pa microscope kapena galasi.
HPMC yoyesedwa imatha kuonedwa ngati granolar imakhazikika kapena makristals pansi pa ma microscope kapena galasi.
Kuchokera pazinthu ziti zomwe mungazindikire zabwino ndi zovuta za hydroxypropyl methyl cellulose?
1.white degree
Ngakhale kuyera sikungadziwe ngati HPMC ndikosavuta kugwiritsa ntchito, ndipo ngati othandizira oyera akuwonjezeredwa adawonjezeredwa pakupanga, uzikhudza mtundu wake. Komabe, ambiri mwazinthu zabwino zimakhala ndi kuyera kwabwino.
2.Fineness
Chisangalalo cha HPMC nthawi zambiri chimakhala ndi mauna 80 ndi 100 mesh, ndipo ndikulimbikitsa zabwino, nthawi zonse, zabwinoko.
3.Transmittancence
Ikahydroxypropyl methyl cellulose (hpmc)m'madzi kuti apange colloid wowonekera, ndikuyang'ana mawonekedwe ake opepuka. Mphamvu yopepuka, yabwinoko, yosonyeza kuti pali zinthu zochepa zomwe zili mkati mwake. Kufalikira kwa vatirs nthawi zambiri kumakhala kwabwino, pomwe ya zopingasa zamphamvu ndizoyipa.
4.Goget
Kukula kwakukulu kwamphamvu, chochuluka. Kutanthauzira kwake ndi kwakukulu, nthawi zambiri chifukwa cha gulu la hydroxypropyl mkati mwake ndi lalitali, ndipo zomwe zili ndi hydroxypyl gululi ndizokwera, kusungidwa kwamadzi ndikwabwino.
