Cov Khoom Siv Zoo Tshaj Plaws Hauv Cellulose ether

Cov khoom lag luam zoo ether yog yam ntxwv los ntawm lawv txoj kev coj dawb huv, xwm yeem, thiab kev ua tau zoo thoob plaws cov ntawv thov. Cov neeg muaj kev hais ua haujlwm ntawm cellulose tau siv dav hauv kev lag luam xws li kev tsim kho, chaw muag tshuaj, zaub mov, thiab tu tus kheej. Nov yog qee qhov tseem ceeb ntawm cov cwj pwm ntawm cov khoom lag luam zoo ether ether:

1. Purity: Muaj cov neeg muaj txiaj ntsig zoo cellulose yog tsim tawm siv cov khoom siv ua kom huv raws li cov khoom siv uas pib ua kom muaj kev cuam tshuam zoo tsawg. Qhov no ua rau cov khoom lag luam uas muaj kev coj dawb huv, pub dawb los ntawm kev ua paug uas tuaj yeem cuam tshuam kev ua haujlwm lossis ua rau muaj kev cuam tshuam zoo hauv kev siv.
2. Kev sib xws: Kev sib xws nyob rau hauv cov khoom lag luam zoo yog qhov tseem ceeb rau kev ua kom tau kev ua tau zoo thiab sib txawv hauv cov qauv. Cov neeg muaj kev ua siab zoo ntawm cellulos ua kom muaj zog ua kom muaj zog thiab tshuaj siv tshuaj, suav nrog cov ntsiab lus loj (DS), thiab solubility, batch tom qab batch.
3. Kev Ua Kom Zoo: Cov neeg muaj kev ua siab zoo ntawm cellulose yog tsim los kom xa cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb. Qhov no suav nrog kev ua kom muaj kev xav, xws li cov khoom siv viscosity, thiab dej ua ke) kom tau raws li cov kev cai sib txawv ntawm kev lag luam sib txawv thiab kev siv.
4. Kev nthuav dav ntau ntawm cov qib kawm thiab cov lus qhia tshwj xeeb: ether cov cellulose muaj ntau cov qhab nia thiab cov kev qhia tshwj xeeb rau ntau cov neeg siv khoom thiab cov kev thov. Qhov no suav nrog kev hloov pauv hauv viscosity, ceeb toom molecosity, degree ntawm kev hloov pauv, thiab lwm yam loj me, thiab lwm yam vagulation tsim.
5. Kev Txhawb Nqa thiab Kev Tshaj Tawm: Cov khoom lag luam zoo ether muab cov khoom lag luam thiab kev txawj ntse tshaj plaws rau lawv cov ntawv thov tshwj xeeb. Qhov no suav nrog cov lus qhia ntawm cov lus qhia, ua cov kev tshuaj xyuas ua tau zoo, thiab muab kev pab daws teeb meem los sis teeb meem uas yuav tshwm sim.
6. Ua raws li cov qauv kev cai: cov khoom lag luam zoo nyeem nrog cov qauv kev coj ua thiab kev tswj hwm kev tswj hwm lawv li hauv ntau yam kev lag luam thiab kev siv. Qhov no suav nrog kev coj ua raws li cov kws muag tshuaj (xws li USP, EP, JP) rau cov kev tswj hwm kev nyab xeeb rau cov khoom noj thiab dej haus.
7. Kev ntseeg zoo thiab ntawv pov thawj zoo: etle cellulose ether cov kev ntsuas), iso kev ua lag luam zoo) kom ntseeg tau tias cov khoom lag luam zoo, muaj zog , thiab kev nyab xeeb.
8. Kev ua kom muaj kev lom zem thiab tsim cov kev coj ua: cov khoom lag luam zoo ether ntiav thoob plaws hauv cov txheej txheem hauv kev tsim khoom. Qhov no suav nrog cov ntaub ntawv muaj npe nrov raw, siv kev ua haujlwm hauv eco-phooj ywg tsim tawm, txo cov kev pov tseg thiab cov pa ncho, thiab tau txais cov kev muaj kuab.

Cov khoom lag luam zoo ether yog yam ntxwv los ntawm lawv cov qib, kev txhawb nqa dav dav, kev saib xyuas zoo, thiab cog lus kom muaj kev ruaj khov. Xaiv lub npe nrov xa nrog cov ntaub ntawv sau tseg ntawm cov khoom lag luam zoo thiab cov kev pabcuam zoo rau cov neeg siv khoom yog qhov ua tau zoo hauv ntau yam kev siv.
