Daim ntawv thov
1, Ib qho kev siv ntau tshaj plaws ntawm Hydroxypropyl Methyl Cellulose yog nyob rau hauv kev tsim kho kev lag luam. Nws yog siv los ua cov thickener thiab binder hauv cov cement- thiab gypsum-raws li cov khoom lag luam, suav nrog mortar, grout, plaster, thiab cov cement sib koom ua ke, txhawm rau txhim kho lawv cov kev ua haujlwm, lub zog, thiab cov khoom tuav dej. Nws kuj ua raws li kev tiv thaiv colloid, tiv thaiv kev teeb tsa thiab kev sib cais ntawm cov khoom sib xyaw. Tsis tas li ntawd, raws li cov dej-soluble polymer, nws txhim kho kev khi thiab adhesion ntawm cov khoom siv, uas ua rau cov khoom siv ruaj khov thiab homogeneous.
2, Lwm daim ntawv thov loj ntawm Hydroxypropyl Methyl Cellulose yog nyob rau hauv kev lag luam kws tshuaj. Nws yog siv los ua ib daim ntawv khi, thickener, thiab disintegrant nyob rau hauv cov ntsiav tshuaj formulations los txhim kho cov ntsiav tshuaj lub zog, disintegration, thiab dissolution zog. Qhov no yog cov tshuaj tsis muaj tshuaj lom thiab tsis muaj zog, ua rau nws tsim nyog rau kev siv tshuaj hauv qhov ncauj thiab tshuaj pleev ib ce. Nws kuj tseem siv tau rau hauv lwm cov khoom siv tshuaj xws li tshuaj kho qhov muag thiab tshuaj tua kab mob vim nws cov muco-adhesive zog thiab yooj yim ntawm formulation.
3, Hauv kev lag luam khoom noj khoom haus, HPMC yog siv los ua cov thickener, emulsifier, thiab stabilizer hauv cov khoom noj khoom haus, xws li cov khoom noj siv mis, cov khoom ci, cov kua ntses, thiab cov zaub xam lav. Nws kuj yog siv nyob rau hauv encapsulation ntawm cov vitamins thiab minerals kom zoo stability thiab bioavailability. Nws yog ib qho kev nyab xeeb thiab ntuj tsim nyob rau hauv cov zaub mov, ua rau nws ib tug nrov lwm txoj rau hluavtaws additives.
