Indlela yokuphelisa iHydroxypropyl methylcellulose (HPMC):

Xa iimveliso ze-hydroxypropyl methylcellulose (HPMC) zongezwa ngokuthe ngqo emanzini, ziya kubumbana kwaye zinyibilike, kodwa oku kupheliswa kucotha kakhulu kwaye kunzima. Kukho iindlela ezintathu ezicetyisiweyo zokuphelisa ngezantsi, kwaye abasebenzisi banokukhetha eyona ndlela ifanelekileyo ngokusetyenziswa kwabo:

1. Indlela yamanzi ashushu: Ekubeni i-hydroxypropyl methylcellulose (HPMC) ayinyibiliki emanzini ashushu, isigaba sokuqala se-hydroxypropyl methylcellulose (HPMC) sinokusasazwa ngokulinganayo kumanzi ashushu, kwaye emva kokuba ipholile, ezintathu zendlela eqhelekileyo ichazwa njenge. ilandelayo:

1). Beka umlinganiselo ofunekayo wamanzi ashushu kwisikhongozeli kwaye ufudumale ukuya kuma-70°C. Ngokuthe ngcembe yongeza i-hydroxypropyl methylcellulose (HPMC) phantsi kokuvuselela okucothayo, i-hydroxypropyl methylcellulose (HPMC) iqalisa ukudada phezu kwamanzi, kwaye ngokuthe ngcembe yenze i-slurry, ipholise i-slurry phantsi kokuvuselela.

2). Fudumeza i 1/3 okanye 2/3 (umlinganiselo ofunekayo) wamanzi kwisikhongozeli kwaye uyifudumeze ukuya kuma 70°C. Ngokwendlela ye-1), ukusabalalisa i-hydroxypropyl methylcellulose (HPMC) ukulungiselela i-slurry yamanzi ashushu; Emva koko yongeza umlinganiselo oseleyo wamanzi abandayo okanye amanzi omkhenkce kwisikhongozeli, uze wongeze i-hydroxypropyl methylcellulose (HPMC) esele ikhankanywe ngasentla yamanzi ashushu eludaka emanzini abandayo, kwaye ushukumise, emva koko upholise umxube.

3). Yongeza i-1/3 okanye i-2/3 yomlinganiselo ofunekayo wamanzi kwisikhongozeli kwaye uyifudumeze ukuya kuma-70°C. Ngokwendlela ye-1), ukusabalalisa i-hydroxypropyl methylcellulose (HPMC) ukulungiselela i-slurry yamanzi ashushu; Umlinganiselo oseleyo wamanzi abandayo okanye e-ice wongezwa kwi-slurry yamanzi ashushu kwaye umxube upholile emva kokuvuselela.

2. Indlela yokuxuba i-powder: i-hydroxypropyl methylcellulose (HPMC) i-powder particles kunye nenani elilinganayo okanye elikhulu lezinye izithako ze-powdery zichithwa ngokupheleleyo ngokuxuba okomileyo, kwaye emva koko zichithwa emanzini, ngoko i-hydroxypropyl methylcellulose Base cellulose (HPMC) inokuchithwa ngaphandle kwe-agglomeration. . 3. Indlela yokumanzisa i-solvent ye-Organic: i-pre-disperse okanye imanzi i-hydroxypropyl methylcellulose (HPMC) kunye ne-solvents ye-organic efana ne-ethanol, i-ethylene glycol okanye i-oyile, uze uyichithe emanzini. Ngeli xesha, i-hydroxypropyl methylcellulose (HPMC) inokuchithwa kakuhle.
