Hpmc Powder Inoshandiswainogona kuparadzirwa zvakaenzana uye zvinobudirira musimende dhaka uye gypsum yakavakirwa zvigadzirwa, kuputira zvese zvakasimba zvimedu uye kugadzira firimu rekunyorova. Iyo mwando mugadziko inoburitswa zvishoma nezvishoma kwenguva yakati rebei, uye inopinda hydration reaction ine inorganic simende zvinhu, nekudaro kuve nechokwadi chekubatanidza kusimba uye kusimba kwekumanikidza kwezvinhu.
Naizvozvo, mukupisa kwakanyanya kwezhizha kuvaka, kuitira kuti uwane mhedzisiro yekuchengetedza mvura, zvinodikanwa kuwedzera huwandu hwakakwana hwehydroxypropyl methyl cellulosemaererano nefomula, kana zvisina kudaro matambudziko emhando akadai sekusakwana hydration, kuderedzwa kwesimba, kuputika, gollowing, uye detachment inokonzerwa nekukurumidza kuoma ichaitika, uye ichawedzerawo kuoma kwevashandi mukuvaka. Sezvo tembiricha inoderera, huwandu hwehydroxypropylmethylcellulose hunogona kuderedzwa zvishoma nezvishoma, uye iyo yakafanana yekuchengetedza mvura inogona kuwanikwa.
Kuchengetwa kwemvura kwehydroxypropyl methyl cellulose kunokonzerwa nekupisa uye zvinotevera zvinhu:
1. Homogeneity yehydroxypropyl methyl cellulose
Homogeneoushydroxypropyl methyl cellulose, Methoxy boka uye hydroxypropyl zvakagoverwa zvakaenzana, uye chiyero chekuchengetedza mvura chakakwirira.
2. Kupisa kweHPMC thermal gel
Thermal gel ine tembiricha yakakwirira uye chiyero chekuchengetedza mvura; Pane zvinopesana, mwero wekuchengetedza mvura wakaderera.
3. Hydroxypropylmethylcelluloseviscosity
Kana viscosity yeHPMCinowedzera, chiyero chekuchengetedza mvura chinowedzerawo; Kana iyo viscosity inosvika pane imwe nhanho, kuwedzera kwekuchengetedza mvura kunowanzova zvishoma nezvishoma.
4. Kuwedzera huwandu hwehydroxypropyl methyl cellulose
Iyo yakakura huwandu hwehydroxypropyl methyl cellulose yakawedzerwa, iyo yakakwira mwero wekuchengetedza mvura uye zvirinani maitiro ekuchengetedza mvura. Muchikamu che 0.25-0.6% kuwedzera, chiyero chekuchengetedza mvura chinowedzera nokukurumidza nekuwedzera kwekuwedzera; Sezvo huwandu hwekuwedzera hunowedzera, kuwedzera kwemaitiro ekuchengetedza mvura kunoderera
