Cov khoom
Sodium carboxymethyl cellulose (CMC)
CMC yog cov khoom siv dav thiab yooj yim tshaj plaws hauv cellulose ether, uas feem ntau hu ua "kev lag luam MSG".
CMC muaj ntau yam tseem ceeb, xws li kev sib sau siab viscosity colloid, tov, nplaum, thickening, ntws, emulsification, dispersing, shaping, dej txuag, tiv thaiv colloid, zaj duab xis tsim, acid kuj, ntsev thiab turbidity kuj, thiab yog tsis muaj teeb meem nyob rau hauv physiology. .Yog li ntawd, CMC tau siv dav hauv cov khoom noj, tshuaj, tshuaj txhua hnub, roj, ntawv ua, textile, kev tsim kho thiab lwm yam.
(1) rau drilling thiab drilling cov roj thiab cov nkev, zoo khawb thiab lwm yam dej num
① Cov av nkos uas muaj CMC tuaj yeem ua rau phab ntsa zoo tsim lub ncuav mog qab zib nyias thiab muaj zog nrog cov permeability tsawg, thiab txo cov dej tsis zoo.
② Tom qab CMC muab tso rau hauv cov av nkos, lub tshuab drilling tuaj yeem tau txais lub zog pib qis qis, ua kom cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab muab cov khib nyiab pov tseg hauv qhov av nkos sai.
③ Drilling av nkos muaj qee lub sijhawm muaj sia nyob, zoo li lwm yam kev cuam tshuam raug tshem tawm, thiab tuaj yeem ruaj khov thiab txuas ntxiv los ntawm 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 khaws cia.
⑤ CMC yog siv los ua tus neeg sawv cev kho mob ntawm cov av nkos ntxuav cov kua dej, uas tuaj yeem tiv taus cov pa phem ntawm ntau cov ntsev soluble.
⑥ Lub slurry nrog CMC muaj kev ruaj ntseg zoo, thiab cov dej poob tuaj yeem txo tau txawm tias qhov kub siab tshaj 150 ℃.
CMC nrog cov viscosity siab thiab siab hloov degree yog tsim nyog rau kev ceev thiab cmc nrog cov viscosity tsawg dua yog tsim nyog rau cov av nkos nrog siab ntom.CMC yuav tsum raug xaiv raws li hom av nkos, thaj chaw, qhov tob tob thiab lwm yam kev mob.
(2) CMC yog siv los ua sizing tus neeg sawv cev hauv textile thiab luam ntawv thiab dyeing industries, thiab siv rau sizing ntawm paj rwb, silk wool, tshuaj fiber ntau, blended fabrics thiab lwm yam ntaub ntawv muaj zog;
(3) CMC tuaj yeem siv los ua tus neeg sawv cev du thiab loj hauv kev lag luam ntawv.Cov ntawv tuaj yeem txhim kho lub zog tensile los ntawm 40% - 50%, compressive fracture degree nce 50%, thiab lub peev xwm kneading nce 4-5 zaug los ntawm kev ntxiv 0.1% rau 0.3% CMC.
(4) CMC tuaj yeem siv los ua cov av adsorbent thaum nws ntxiv rau cov khoom siv hluavtaws;Kev siv tshuaj txhua hnub, xws li glycerine aqueous tov ntawm CMC hauv kev lag luam tshuaj txhuam hniav, yog siv los ua cov kua nplaum ntawm cov tshuaj txhuam hniav;Kev lag luam kws tshuaj yog siv los ua thickener thiab emulsifier;CMC aqueous tov yog siv raws li flotation tom qab viscosity nce.
(5) nws tuaj yeem siv los ua cov nplaum, plasticizer, tshem tawm tus neeg sawv cev thiab kho tus neeg sawv cev rau glaze hauv kev lag luam ceramic.
(6) nws yog siv rau kev tsim kho kom txuag dej thiab muaj zog
