Hydroxypropyl Methylcellulose (HPMC) yakakosha polymer cellulose ether, inoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, zvizorwa uye mamwe minda. Mudhaka rakaoma, HPMC chinhu chakakosha chekuwedzera, chinonyanya kushandiswa kuvandudza kunamatira kwayo, kuchengetedza mvura, kuita kwekuvaka uye mamwe maitiro, kunyanya mumashandisirwo ane yakakwirira viscosity zvinodiwa.
Basic maitiro eHPMC
HPMC inogadziriswa kemikari kubva kune yakasikwa polymer material cellulose. Iyo ine yakanaka solubility yemvura, nonionicity uye biodegradability, izvo zvinoita kuti ive ine hushamwari nharaunda uye yakachengeteka yekuwedzera. HPMC ine yakanakisa kukora, firimu-kuumba, kuchengetedza mvura, kumisa uye emulsifying zvivakwa, izvo zvinoita kuti ishandiswe zvakanyanya mudhaka rakaoma.
Basa reHPMC mudhaka rakaoma
Kuchengetwa kwemvura: HPMC inogona kuvandudza zvakanyanya kuchengetedza kwemvura kuita kwedhaka rakaoma uye kuderedza kurasikirwa kwemvura panguva yekuvaka. Izvi zvakakosha kudzivirira kuputika uye kurasikirwa kwesimba kunokonzerwa nedhaka kurasikirwa nemvura nekukurumidza. Kunyanya mumamiriro ekunze anopisa uye akaoma, kuchengetedza mvura kunonyanya kukosha.
Kukora mhedzisiro: HPMC inogona kunyatso kuwedzera viscosity yedhaka rakaoma, ichiita kuti ive yakawanda mvura uye inoshanda panguva yekuvaka. Yakakwira viscosity HPMC inogona kuwedzera kusagirira kwayo mudhaka rakaoma, ichiita kuti ive yakakodzera kuvakwa panzvimbo dzakamira kana dzakamiswa.
Kuvandudzwa kwekuita kwekuvaka: HPMC inogona kuvandudza kushanda kwedhaka rakaoma, zvichiita kuti zvive nyore kupararira uye chiyero. Ichi chivakwa chakanyanya kukosha mukuvaka kwakatetepa-layer, sekupurasita madhaka anoshandiswa mukuisa matairi uye mukati nekunze kushongedza madziro.
Simba rekubatanidza: HPMC inogona kuvandudza kusimba kwechisungo chedhaka rakaoma, kunyanya kupa zvirinani kubatanidza kuita pakati peiyo base zvinhu uye pamusoro pezvinhu. Izvi zvakakosha kuve nechokwadi chemhando yebasa uye kuwedzera hupenyu hwechivako.
Maitiro ekushandisa HPMC uye matanho ekudzivirira
Kana uchiwedzera HPMC kune yakaoma dhaka, inowanzosanganiswa nezvimwe zvinhu nenzira yehupfu yakaoma. Huwandu hwekuwedzera hweHPMC hunowanzo pakati pe0.1% uye 0.5%, iyo inogadziriswa zvinoenderana neyakasiyana mashandisirwo ezvinodiwa uye zvigadzirwa mafomula. Paunenge uchishandisa, kutarisisa kunofanirwa kubhadharwa kune kwayo kunyungudika maitiro kuti udzivise agglomeration. Zvinowanzokurudzirwa kuti pakusanganisa dhaka rakaoma, HPMC inofanira kunyatsosanganiswa nedzimwe poda, uye ipapo mvura inofanira kuwedzerwa kuti iite kuti ione kuti yanyungudutswa uye yakapararira.
Sechinhu chakakosha chekuwedzera mune yakakwirira-viscosity yakaoma dhaka, hydroxypropyl methylcellulose inotora chinzvimbo chakakosha mukuvaka kwemazuva ano nekuda kwekuita kwayo kwakanaka. Nekuvandudza kuchengetwa kwemvura, kukora mhedzisiro, kuita kwekuvaka uye kusimba kwechisungo chedhaka rakaoma, HPMC inopa mhinduro inoshanda yekuvandudza mashandiro ezvivakwa zvekuvaka. Panguva imwecheteyo, sechinhu chine hushamwari hwezvakatipoteredza, HPMC ine tarisiro yakakura yekushandisa mumunda wezvigadzirwa zvekuvaka.
