Yuav ua li cas xaiv HPMC txoj cai
1. Raws li tus qauv: Raws li cov qauv sib txawv ntawm ntau yam putties, viscosity qauv ntawm hydroxypropyl methylcellulose thiab methylcellulose kuj txawv. Lawv siv los ntawm 40,000 mus rau 100,000. Nyob rau tib lub sijhawm, fiber ntau Vegetarian ether tsis tuaj yeem hloov lub luag haujlwm ntawm lwm cov binders, ntxiv cellulose ether tsis tau txhais hais tias cov khoom xyaw ntawm lwm cov binders tuaj yeem txo.
2. Koj puas xav tau dej txias dispersible cellulose ether: Cellulose ether (xws li hydroxypropyl methylcellulose thiab methylcellulose) yog ib qho surfactant nrog siab viscosity tom qab dissolution. Nws yog qhov laj thawj ntawm qhov xwm txheej no yog tias cov cellulose ether zoo tib yam ntxiv rau hauv dej, nws yog ib qho yooj yim los tsim ib lub pob, thiab sab nraud ntawm lub pob tau yaj mus rau hauv cov tshuaj tuab heev, thiab sab hauv yog qhwv, thiab nws nyuaj heev. rau dej nkag mus rau hauv, ua rau tsis zoo dissolution. . Qhov chaw kho cellulose ether (uas tuaj yeem ncua kev sib cais) yuav tsis zoo li qhov no, thiab tuaj yeem tawg tau zoo nyob rau hauv dej txias (txo qis, thiab maj mam yaj tom qab dispersion). Nws yog ib qho kev xaiv zoo kom nkag siab txog qhov sib txawv saum toj no.
1. Rau qhov sib xyaw qhuav ntawm sab hauv thiab sab nrauv phab ntsa putty, vim hais tias cov cellulose ether tau zoo dispersed nyob rau hauv cov khoom thaum lub sij hawm qhuav mixing txheej txheem, yuav tsis muaj agglomeration. Yog li ntawd, nws raug nquahu kom siv hom hom (tsis yog dej txias dispersion hom), vim tias qhov sib cais ntawm cov hom sib txawv yog sai dua li cov dej txias dispersion hom, uas ua rau lub sijhawm tos ntev los ntawm kev sib xyaw slurry rau kev tsim kho.
2. Rau kev npaj ntawm putty uas ncaj qha dissolves cellulose ether (xws li hydroxypropyl methylcellulose thiab methylcellulose) nyob rau hauv dej thiab sib tov nrog lwm yam ntaub ntawv, nws yog pom zoo kom siv dej txias dispersion hom cellulose ether. Qhov chaw kho cellulose ether tuaj yeem ua kom zoo hauv dej txias thiab yaj (tuaj yeem ncua kev sib cais)
