01. Kusiyana pakati pa Hydroxypropyl methyl ndi Hydroxypropyl methyl
Maonekedwe: Wopukutira wakhwima wakhwawa umawoneka wopanda homogeneous, pakati pa 0,3 ndi 0,4 g / ml. Amylum amamangiriza wowuma motero HPCM ndi madzi komanso opsinjika kuposa ena okhazikika.
Zochitika: Wowuma wodzaza ndi wowuma, wa hpm ufa, fiber pansi pa microscope kapena galasi louma, hpcm mtundu wa wowuma kapena wowuma ndi mphodza.
Fungo: ma hydroxypropyl methylcellulose hpmc sangathe kununkhiza ammonia, wowuma ndi mowa; Wosankhidwa hydroxpyll methylcellulose hpmc amatha kununkhiza mitundu yonse yonunkhira, ngakhale zitakhala zopanda nzeru.
Madzi am'madzi: Oyera, HPMC Methyllulose Demethypropyl a brinzolamide am'madzi ndi momveka bwino, kuwala kopepuka kwamadzi ≥ 97%; Kuchepetsedwa Hydrolyzd Cellulose - HPMC hydrolyzd cellulose ndi ku Turbid, kusunga madzi osasunga 80%.
02. Kusungidwa kwa methyl cellulose kutentha kwambiri ndi chizindikiro chofunikira kudziwa mtundu wa methyl cellulose ether ether ether ether. Zinthu monga kutentha kwa mpweya, kutentha kwa mpweya ndi liwiro la mphepo kumakhudza kusamvana kwa zinthu zotsekemera ndi gypsum. Chifukwa chake, kuwonjezera kuchuluka kofanana kwa zinthu za HPMC nthawi zosiyanasiyana, pali kusiyana kwina kuzinthu zopulumutsa madzi. M'machitidwe ena, zotsatira za kunyowa serosa zitha kuwongoleredwa pochepetsa kuchuluka kwa HPMC yowonjezeredwa. Hydroxypypypyl methylcellulose hpmc imatha kuthana bwino ndi vuto la kutentha kwamadzi.
Cellose yapamwamba kwambiri ya methyl imatha kuperekedwa mwamphamvu mu matope a simenti ndi zojambula zopaka, zomwe zimatulutsidwa pang'onopang'ono kuchokera ku zinthu zosanjikiza ndikupanga mphamvu zopindika, potero. Hpmc cellulose methl propoxylate ndi yunifolomu, ndi mpweya wa acid ndi ma hydrogen a atomu iliyonse ya hydroxyl amatha kusintha madzi otsika kulowa Madzi opulumutsa zikopa, motero amawongolera madzi osakwanira madzi, kutenthetsa kutentha, komanso chinyezi cha madzi ambiri.
Chifukwa cha kuwongoleredwa kwambiri m'chilimwe, kuti mukwaniritse zotsatira za kupulumutsa madzi, ndikofunikira kuwonjezera zinthu zapamwamba za HPMC malinga ndi njira, apo ayi zimayambitsa zovuta monga kuwuma kwambiri, kuwonongeka, kopanda pake, kopanda pake Kugwedezeka ndikugwetsa, ndikuwonjezera zovuta zomanga ogwira ntchito. Mukutsitsa kutentha, ndizotheka pang'onopang'ono kuchepetsa kuchuluka kwa HPMC yowonjezeredwa ndikupeza zotsatira zomwezo.
