Indlela yokukhetha i-HPMC efanele
1. Ngokusho kwemodeli: Ngokwamafomula ahlukene we-putty ahlukahlukene, amamodeli we-viscosity we-hydroxypropyl methylcellulose ne-methylcellulose nawo ahlukile. Zisetshenziswa kusukela ku-40,000 kuya ku-100,000. Ngesikhathi esifanayo, i-fiber Vegetarian ether ayikwazi ukuthatha indawo yezinye izibophezelo, ukwengeza i-cellulose ether akusho ukuthi izithako zezinye izibophezelo zingancishiswa.
2. Uyawadinga amanzi abandayo i-cellulose ether ehlakazekayo: I-Cellulose ether (kuhlanganise ne-hydroxypropyl methylcellulose ne-methylcellulose) iyisisetshenziswa esine-viscosity ephezulu ngemva kokuncibilika. Kuyisizathu salolu hlobo ukuthi uma i-cellulose ether evamile yengezwa emanzini, kulula ukwenza ibhola, futhi ingaphandle lebhola liye lahlakazeka libe yisisombululo esinzima kakhulu, futhi ngaphakathi kuhlanganiswe, futhi kunzima. ukuze amanzi angene ngaphakathi, okuholela ekuncibilikeni okungekuhle. . I-cellulose ether efakwe phezulu (engabambezela ukuchithwa) ngeke ibe kanje, futhi ingahlakazwa kahle emanzini abandayo (ukulibaziseka ukuchithwa, futhi kancane kancane incibilike ngemva kokuhlakazeka). Kuyisinqumo esihle ukuqonda umehluko ongenhla.
1. Nge-putty yodonga lwangaphakathi oluxubene omile, ngenxa yokuthi i-cellulose ether ihlakazeke kahle ezintweni ngesikhathi senqubo yokuxuba okomile, ngeke kube khona i-agglomeration. Ngakho-ke, kunconywa ukusebenzisa uhlobo oluvamile (uhlobo lokuhlakazeka kwamanzi angewona abandayo), ngoba izinga lokuhlakazeka lohlobo oluvamile liyashesha kunelohlobo lokuhlakazeka kwamanzi abandayo, okunciphisa isikhathi sokulinda kusukela ekuhlanganiseni i-slurry kuya ekwakhiweni.
2. Ukuze kulungiswe i-putty encibilikisa ngokuqondile i-cellulose ether (okuhlanganisa i-hydroxypropyl methylcellulose ne-methylcellulose) emanzini futhi ixutshwe nezinye izinto, kunconywa ukusebenzisa amanzi abandayo okusabalalisa uhlobo lwe-cellulose ether. I-cellulose ether efakwe phezulu ingahlakazwa kahle emanzini abandayo futhi incibilike (ingabambezeleka ukuhlakazeka)
