Sodium carboxymethyl cellulose yog siv dav hauv kev lag luam tshuaj xws li ntsiav tshuaj, tshuaj pleev, hnab, thiab tshuaj paj rwb swabs. Sodium carboxymethyl cellulose muaj cov thickening zoo heev, tshem tawm, stabilizing, cohesive, dej tuav thiab lwm yam dej num thiab yog siv dav hauv kev lag luam kws tshuaj. Hauv kev lag luam kws tshuaj, sodium carboxymethyl cellulose yog siv los ua tus neeg sawv cev ncua, tus neeg sawv cev thickening, thiab tus neeg sawv cev flotation hauv kev npaj ua kua, raws li cov gel matrix hauv cov khoom npaj ib nrab, thiab ua ib qho kev sib khi, tus neeg sawv cev disintegrating nyob rau hauv cov ntsiav tshuaj tov thiab qeeb-tso tawm excipients. .
Cov lus qhia rau kev siv: Hauv kev tsim cov sodium carboxymethyl cellulose, CMC yuav tsum tau yaj ua ntej. Muaj ob txoj hauv kev ib txwm:
1. Sib tov CMC ncaj qha nrog dej los npaj cov kua nplaum zoo li cov kua nplaum, tom qab ntawd siv rau tom qab siv. Ua ntej, ntxiv ib qho dej huv rau hauv lub tank batching nrog lub tshuab ua kom nrawm nrawm. Thaum lub tshuab nplawm yog qhib, maj mam thiab sib npaug ntawm CMC rau hauv lub tank batching kom tsis txhob tsim cov agglomeration thiab agglomeration, thiab ua kom nplawm. Ua kom CMC thiab dej fused thiab tag nrho melted.
2. Muab cov CMC nrog cov khoom siv qhuav qhuav, sib tov rau hauv daim ntawv ntawm txoj kev qhuav, thiab yaj hauv cov dej nkag. Thaum lub sijhawm ua haujlwm, CMC yog thawj zaug sib xyaw nrog cov khoom siv qhuav raws li ib qho kev faib ua feem. Cov kev khiav hauj lwm hauv qab no tuaj yeem ua tiav nrog rau cov lus hais saum toj no-hais thawj txoj kev ua kom tiav.
Tom qab CMC yog tsim los rau hauv cov kua dej, nws yog qhov zoo tshaj rau khaws cia rau hauv ceramic, iav, yas, ntoo thiab lwm yam ntim, thiab nws tsis tsim nyog siv cov thawv hlau, tshwj xeeb tshaj yog hlau, txhuas thiab tooj liab ntim. Vim hais tias, yog tias CMC aqueous tov yog nyob rau hauv kev sib cuag nrog lub thawv hlau rau lub sij hawm ntev, nws yog ib qho yooj yim ua rau cov teeb meem ntawm deterioration thiab viscosity txo. Thaum CMC aqueous tov coexists nrog txhuas, hlau, tin, nyiaj, tooj liab thiab qee yam hlau, cov tshuaj tiv thaiv nag lossis daus yuav tshwm sim, txo qhov ntau thiab qhov zoo ntawm CMC hauv cov tshuaj.
Kev npaj CMC aqueous tov yuav tsum tau siv kom sai li sai tau. Yog tias CMC aqueous tov tau khaws cia rau lub sijhawm ntev, nws yuav tsis tsuas cuam tshuam rau cov khoom nplaum thiab kev ruaj ntseg ntawm CMC, tab sis kuj raug kev txom nyem los ntawm cov kab mob thiab kab, yog li cuam tshuam rau kev tu cev zoo ntawm cov khoom siv raw.
