3. Kev tu tus kheej thiab kev lag luam tshuaj pleev ib ce
MHEC yog siv rau hauv ntau yam kev saib xyuas tus kheej thiab cov khoom kom zoo nkauj. Nws yog ib qho tseem ceeb ntawm cov tshuaj zawv plaub hau, tshuaj pleev thiab tshuaj pleev plaub hau. Nws tsim cov yeeb yaj kiab tiv thaiv ib puag ncig cov plaub hau strands, tiv thaiv kom tsis txhob ya raws thaum muab ib qho zoo nkauj, silky. MHEC kuj tseem siv rau hauv cov khoom tu tawv nqaij xws li cream thiab tshuaj pleev ib ce vim nws txhim kho kev ntxhib los mos thiab viscosity ntawm cov khoom. Nws lub peev xwm tuav dej pab kom cov tawv nqaij hydrated.
4. Kev lag luam kws tshuaj
MHEC yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug binder, disintegrant thiab thickener. Nws yog ib qho tseem ceeb ntawm cov khoom siv tshuaj xws li ntsiav tshuaj thiab tshuaj ntsiav. MHEC txhim kho qhov fluidity ntawm cov khoom xyaw tshuaj nquag, ua rau kom muaj kev sib cais ntawm cov tshuaj, thiab npog qhov tsis zoo ntawm cov tshuaj.
Qhov zoo ntawm Methyl Hydroxyethyl Cellulose (MHEC)
1. Lub peev xwm tuav dej
MHEC muaj peev xwm tuav tau dej zoo heev, ua rau nws muaj qhov tseem ceeb hauv ntau yam kev siv. Hauv kev tsim kho kev lag luam, MHEC txhim kho cov dej tuav lub peev xwm ntawm cov khoom sib tov sib xyaw, tiv thaiv cov dej nrawm nrawm thiab txhim kho kev ua haujlwm ntawm cov khoom sib tov. Hauv kev lag luam zaub mov, MHECs pab khaws cov dej noo thiab tiv thaiv kom qhuav, txhim kho kev ntxhib los mos thiab hnov qab txog cov khoom noj. Hauv kev tu tawv nqaij thiab tshuaj pleev ib ce, MHEC pab khaws cov tawv nqaij noo thiab txhawb nws cov tsos mob zoo.
2. Thickener
MHEC ua raws li cov thickener, ua kom cov viscosity thiab sib xws ntawm ntau yam khoom. Hauv kev lag luam zaub mov, MHEC thickens cov kua ntses, gravy thiab kua zaub, txhim kho lawv cov kev ntxhib los mos thiab qhov ncauj. Hauv kev lag luam tu tus kheej thiab tshuaj pleev ib ce, MHEC thickens tsuaj zawv plaub hau, txias thiab tshuaj pleev ib ce, yog li txhim kho kev ua haujlwm ntawm cov khoom.
3. Txhim kho kev ntxhib los mos thiab cohesion
MHEC txhim kho kev ntxhib los mos ntawm ntau yam khoom thiab muab kev paub zoo tshaj plaws. Nws txhim kho cov adhesion ntawm cov cement thiab mortar sib tov thiab txhim kho lawv cov khoom sib txuas. Hauv kev lag luam khoom noj khoom haus, MHEC tuaj yeem tsim kom muaj kev ntxhib los mos, zoo nkauj zoo nkauj uas txhim kho qhov kev paub zoo. Nws kuj tseem txhim kho qhov kev ntxhib los mos ntawm cov khoom tu tawv nqaij thiab cov tshuaj pleev ib ce, muab kev zoo nkauj, silky zoo.
4. Tsis muaj tshuaj lom thiab nyab xeeb
MHEC tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau kev siv ntau yam kev siv. Nws tau pom zoo los ntawm US Food and Drug Administration (FDA) siv rau hauv cov khoom noj thiab dej haus. Nws tseem muaj kev nyab xeeb los siv hauv kev saib xyuas tus kheej thiab tshuaj.
nyob rau hauv xaus
