Indlela yokukhetha i-HPMC efanelekileyo
1. Ngokwemodeli: Ngokweendlela ezahlukeneyo ze-putty ezahlukeneyo, iimodeli ze-viscosity ze-hydroxypropyl methylcellulose kunye ne-methylcellulose nazo zihluke. Zisetyenziswa ukusuka kwi-40,000 ukuya kwi-100,000. Ngelo xesha, i-fiber Vegetarian ether ayikwazi ukuthatha indawo yezinye izibophelelo, ukongeza i-cellulose ether ayithethi ukuba izithako zezinye izibophelelo zingancitshiswa.
2. Ngaba ufuna amanzi abandayo e-disperible cellulose ether: I-cellulose ether (kubandakanywa ne-hydroxypropyl methylcellulose kunye ne-methylcellulose) yi-surfactant ene-viscosity ephezulu emva kokuchithwa. Isizathu solu hlobo ukuba ukuba i-ether ye-cellulose eqhelekileyo yongezwa emanzini, kulula ukwenza ibhola, kwaye ingaphandle yebhola iye yachithwa ibe yisisombululo esinzima kakhulu, kwaye ingaphakathi lihlanganiswe, kwaye kunzima. ukuze amanzi angene ngaphakathi, okukhokelela ekunyibilikeni kakubi. . I-ether ye-cellulose ephathwayo ephezulu (enokulibazisa ukuchithwa) ayiyi kuba njalo, kwaye inokuchithwa kakuhle emanzini abandayo (ukulibaziseka ukuchithwa, kwaye ngokuthe ngcembe ichithe emva kokusasazwa). Kulukhetho oluhle ukuqonda lo mahluko ungentla.
1. Kwi-putty yangaphakathi edibeneyo eyomileyo kunye nodonga lwangaphandle, ngenxa yokuba i-ether ye-cellulose iye yahlakazwa kakuhle kwizinto eziphathekayo ngexesha lenkqubo yokuxuba okomileyo, akuyi kubakho i-agglomeration. Ngoko ke, kucetyiswa ukuba kusetyenziswe uhlobo oluqhelekileyo (uhlobo lokuchithwa kwamanzi abandayo), kuba izinga lokuchithwa kohlobo oluqhelekileyo lukhawuleza kunolo hlobo lokusasazwa kwamanzi abandayo, olunciphisa ixesha lokulinda ukusuka ekuxubeni i-slurry ukuya kulwakhiwo.
2. Ukulungiselela i-putty echitha ngokuthe ngqo i-cellulose ether (kubandakanya i-hydroxypropyl methylcellulose kunye ne-methylcellulose) emanzini kwaye ixutywe nezinye izinto, kucetyiswa ukuba kusetyenziswe amanzi abandayo okusasazwa kohlobo lwe-cellulose ether. I-ether ye-cellulose ehlanjululwe phezulu inokuchithwa kakuhle emanzini abandayo kwaye inyibilike (inokulibazisa ukuchithwa)
