Carboxymethyl cellulose (CMC) yog cov tsis muaj tshuaj lom thiab tsis muaj ntxhiab tsw dawb flocculent hmoov nrog kev ua haujlwm ruaj khov thiab yooj yim soluble hauv dej. Nws cov tshuaj aqueous yog ib qho nruab nrab lossis alkaline pob tshab kua nplaum, soluble hauv lwm cov dej-soluble adhesives thiab resins, thiab insoluble hauv organic solvents xws li ethanol. CMC tuaj yeem siv los ua cov nplaum, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, thiab lwm yam.
Carboxymethyl cellulose (CMC) yog cov khoom loj tshaj plaws, feem ntau siv thiab yooj yim tshaj plaws ntawm cov cellulose ethers, feem ntau hu ua "industrial monosodium glutamate".
1. Siv rau roj thiab roj drilling, kev khawb av thiab lwm yam haujlwm
① Cov av nkos uas muaj CMC tuaj yeem ua rau cov phab ntsa zoo li nyias thiab nyuaj lim ncuav mog qab zib nrog cov permeability tsawg thiab txo cov dej tsis zoo.
② Tom qab ntxiv CMC rau hauv av, qhov drilling rig tuaj yeem tau txais qis qis qis qis qis, uas ua rau cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab tib lub sijhawm, nws tuaj yeem muab cov khib nyiab pov tseg hauv qhov av nkos.
③ Zoo li lwm yam kev tshem tawm dispersions, drilling av nkos muaj qee lub sijhawm muaj nyob, uas tuaj yeem ruaj khov thiab txuas ntxiv los ntawm kev ntxiv CMC.
④ Cov av nkos uas muaj CMC tsis tshua muaj kev cuam tshuam los ntawm pwm, yog li nws tsis tas yuav tsum tswj hwm tus nqi pH siab thiab siv cov tshuaj tua kab mob.
⑤ CMC yog siv los ua tus neeg sawv cev kho mob rau cov av nkos flushing kua, uas tuaj yeem tiv taus cov pa phem ntawm ntau cov ntsev soluble.
⑥ Cov slurry uas muaj CMC muaj kev ruaj ntseg zoo thiab tuaj yeem txo cov dej poob txawm tias qhov kub siab tshaj 150 degree.
CMC nrog cov viscosity siab thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas tsis muaj qhov ntom ntom, thaum CMC nrog cov viscosity tsawg thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas muaj qhov ntom ntom. CMC yuav tsum raug xaiv raws li qhov sib txawv xws li hom av nkos, thaj chaw thiab qhov tob tob.
2. Siv nyob rau hauv textile, printing thiab dyeing industries. CMC yog siv los ua sizing tus neeg sawv cev hauv kev lag luam textile rau sizing lub teeb yarns ntawm paj rwb, txhob lo lo ntxhuav thiab ntaub plaub, tshuaj fibers, blends thiab lwm yam ntaub ntawv muaj zog;
3. CMC siv nyob rau hauv daim ntawv kev lag luam yuav siv tau raws li daim ntawv smoothing tus neeg saib xyuas thiab sizing tus neeg saib xyuas nyob rau hauv daim ntawv kev lag luam. Ntxiv 0.1 feem pua ~0.3 feem pua CMC rau cov ntaub so ntswg tuaj yeem ua rau daim ntawv lub zog tensile los ntawm 40 feem pua ~ 50 feem pua, qhov compressive puas los ntawm 50 feem pua, thiab kneading los ntawm 4 ~ 5 zaug .
4. CMC ntxiv rau cov khoom siv hluavtaws tuaj yeem siv ua av adsorbent; Cov tshuaj glycerin aqueous ntawm cov tshuaj niaj hnub xws li CMC hauv kev lag luam tshuaj txhuam hniav yog siv los ua cov pos hniav hauv cov tshuaj txhuam hniav; Siv ua thickener thiab emulsifier hauv kev lag luam kws tshuaj; CMC aqueous tov yog siv rau flotation tom qab thickening.
5. Nws yog siv rau hauv kev lag luam ceramic ua ib qho nplaum, plasticizer, tshem tawm tus neeg sawv cev ntawm glaze tus neeg saib xyuas, xim kho tus neeg saib xyuas, thiab lwm yam.
6. Siv rau lub tsev los txhim kho cov dej tuav thiab lub zog
7. Nws yog siv rau hauv kev lag luam zaub mov. Nyob rau hauv kev lag luam khoom noj khoom haus, CMC nrog high displacement degree yog siv raws li lub thickener ntawm ice cream, kaus poom, instant noodles, ua npuas ncauj stabilizer ntawm npias, thiab lwm yam, thiab nws yog siv raws li lub thickener, binder los yog shaping tus neeg sawv cev nyob rau hauv kev ua jam, syrup, kua txiv hmab txiv ntoo, khoom noj txom ncauj, dej qab zib, thiab lwm yam.
8. Kev lag luam kws tshuaj xaiv CMC nrog cov viscosity tsim nyog raws li cov nplaum, disintegrant thiab ncua kev pab cuam rau cov ntsiav tshuaj.
