Ọna itusilẹ Hydroxypropyl methylcellulose (HPMC):

Nigbati awọn ọja hydroxypropyl methylcellulose (HPMC) ba wa ni afikun taara si omi, wọn yoo ṣe coagulate ati lẹhinna tu, ṣugbọn itusilẹ yii lọra pupọ ati nira.Awọn ọna itusilẹ mẹta ti o daba ni isalẹ, ati pe awọn olumulo le yan ọna irọrun julọ ni ibamu si lilo wọn:

1. Ọna omi gbigbona: Niwọn igba ti hydroxypropyl methylcellulose (HPMC) ko ni tu ninu omi gbona, ipele ibẹrẹ ti hydroxypropyl methylcellulose (HPMC) le wa ni boṣeyẹ tuka ninu omi gbona, lẹhinna nigbati o ba tutu, mẹta A aṣoju ọna ti wa ni apejuwe bi atẹle:

1).Fi omi gbigbona ti a beere sinu apo eiyan ati ki o gbona si iwọn 70 ° C.Diẹdiẹ ṣafikun hydroxypropyl methylcellulose (HPMC) labẹ aruwo lọra, hydroxypropyl methylcellulose (HPMC) bẹrẹ lati leefofo loju omi lori oju omi, lẹhinna di diẹdiẹ kan slurry, tutu slurry labẹ saropo.

2).Ooru 1/3 tabi 2/3 (iye ti a beere) ti omi ninu apoti ki o gbona si 70 ° C.Ni ibamu si awọn ọna ti 1), tuka hydroxypropyl methylcellulose (HPMC) lati mura omi gbona slurry;Lẹhinna fi iye ti o ku ti omi tutu tabi omi yinyin sinu apo, lẹhinna fi omi gbona hydroxypropyl methylcellulose (HPMC) ti a mẹnuba loke si omi tutu, ki o si mu, lẹhinna tutu adalu naa.

3).Fi 1/3 tabi 2/3 ti iye omi ti a beere sinu apo eiyan ki o gbona si 70 ° C.Ni ibamu si awọn ọna ti 1), tuka hydroxypropyl methylcellulose (HPMC) lati mura omi gbona slurry;Awọn ti o ku iye ti tutu tabi yinyin omi ti wa ni ki o si fi awọn gbona omi slurry ati awọn adalu ti wa ni tutu lẹhin saropo.

2. Ọna ti o dapọ lulú: hydroxypropyl methylcellulose (HPMC) awọn patikulu lulú ati iye ti o dọgba tabi ti o pọju ti awọn ohun elo powdery miiran ti wa ni kikun ti a tuka nipasẹ gbigbe gbigbẹ, ati lẹhinna ni tituka ninu omi, lẹhinna hydroxypropyl methylcellulose Base cellulose (HPMC) le ti wa ni tituka laisi agglomeration. .3. Ọna ti o ni iyọda ti ara ẹni: ṣaju-pipa tabi tutu hydroxypropyl methylcellulose (HPMC) pẹlu awọn ohun elo ti o wa ni erupẹ bi ethanol, ethylene glycol tabi epo, ati lẹhinna tu sinu omi.Ni akoko yii, hydroxypropyl methylcellulose (HPMC) tun le ni tituka laisiyonu.
