Ib yam li ntawd, kev lag luam kom hniav zoo sib xyaw ua ke mHEC rau nws lub peev xwm los txhim kho cov kev ntxhib los mos thiab ruaj khov ntawm cov khoom.
5. Zaj duab xis-tsim cov khoom:
MHEC Cov khoom ua yeeb yam ua yeeb yaj kiab ua yeeb yam, ua kom haum rau kev siv hauv cov txheej txheem thiab cov nplaum. Cov xeeb ceem no muaj nqis rau kev tsim ntawm cohesive thiab tiv thaiv zaj duab xis, txhim kho kev ua haujlwm ntawm cov khoom kawg.
Txheej txheem tsim khoom:
Kev tsim tawm MHEC muaj ntau qib, pib nrog kev rho tawm ntawm cellulose los ntawm cov khoom cog-raws. Ntoo pulp yog ib qho pib cov khoom pib, txawm hais tias lwm cov chaw zoo li paj rwb thiab lwm yam nroj tsuag tsis tau. Lub cellulose yog tom qab ntawd raug tshuaj kho mob los ntawm etherification txheej txheem, qhia me me methyl thiab hydroxyethyl pab pawg rau lub cellulose saw. Cov qib degree hloov chaw thiab qhov hnyav muaj peev xwm tswj tau thaum tsim khoom, tso cai rau kev tsim kho MHEC kom tau raws li cov cai thov.
Cov ntawv thov ntawm MHEC:
1. Kev lag luam kev tsim kho:
MHEC nrhiav kev siv dav dav hauv kev tsim kho kev tsim kho. Raws li cov dej rov muag tus neeg saib xyuas, nws txhim kho qhov haujlwm ntawm cov khoom noj kom xis, suav nrog kev xheej thiab guts. Nws cov khoom khi khi ua rau cov qauv tsim ntawm cov khoom ua tau zoo pobzeb, plaster, thiab sib koom ua ke.
2. Tshuaj Kho Mob:
Nyob rau hauv cov tshuaj ntsuam kws tshuaj, MHEC tau ua haujlwm hauv ntau yam qauv. Nws lub luag haujlwm ua tus neeg saib xyuas tuab thiab bindering yog qhov tseem ceeb heev nyob rau hauv kev tsim cov ntsiav tshuaj, tsiav tshuaj, thiab cov txuj ci tseem ceeb. Kev Ntsuas Hluav Taws Xob Cov Tshuaj Ntsuam Xyuas Cov Tshuaj Hluav Taws Xob kuj tseem tuaj yeem tau txais txiaj ntsig los ntawm MHEC cov khoom siv hluav taws xob.
3. Cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej:
Kev pleev tshuaj pleev ib ce feem ntau koom nrog MHEC kom ua tiav cov kev xav paub, kev ruaj khov, thiab viscosity. Cov tshuaj pleev, tshuaj pleev, thiab cov kua nplaum tuaj yeem siv MHEC ua cov tuab thiab tawv, ua rau muaj lub neej zoo thiab lub neej sib txawv ntawm cov khoom no.
4. Cov xim tha xim thiab txheej:
Cov xim thiab cov txheej txheem kev lag luam leverage mHEC rau nws cov thickening thiab ua yeeb yaj kiab-ua yeeb yam. Nws pab rau kev tiv thaiv sagging lossis dripping thaum lub ntawv thov thiab ua rau muaj kev tsim ntawm cov khaub ncaws hnav thiab cov txheej txheem ruaj khov.
