Qhov zoo ntawm carboxymethyl cellulose CMC feem ntau yog nyob ntawm kev daws ntawm cov khoom. Yog tias cov khoom lag luam daws tau meej, muaj cov gel tsawg dua, cov fibers tsis pub dawb, thiab cov pob dub tsawg ntawm impurities. Yeej, nws tuaj yeem txiav txim siab tias qhov zoo ntawm carboxymethyl cellulose yog qhov zoo heev. .
Dissolution thiab Dispersion ntawm Carboxymethyl Cellulose khoom
Sib tov carboxymethylcellulose ncaj qha nrog dej los npaj cov pos hniav rau kev siv. Thaum configuring carboxymethyl cellulose slurry, ua ntej siv ib tug stirring ntaus ntawv ntxiv ib tug npaum li cas ntawm cov dej ntshiab rau hauv batching tank. Tom qab tig lub tshuab nplawm, maj mam thiab sib npaug ntawm cov carboxymethyl cellulose rau hauv lub tank batching, thiab do tsis tu ncua kom cov carboxymethyl cellulose thiab dej fused tag, thiab carboxymethyl cellulose tuaj yeem yaj tag.
Thaum dissolving carboxymethyl cellulose, lub hom phiaj ntawm uniform dispersion thiab tas mus li stirring yog "tiv thaiv caking, txo cov yaj ntawm carboxymethyl cellulose, thiab ua rau kom lub dissolution tus nqi ntawm carboxymethyl cellulose". Feem ntau, lub sijhawm nplawm luv luv dua li lub sijhawm xav tau rau carboxymethylcellulose kom yaj tag.
Thaum lub sij hawm stirring, yog hais tias cov carboxymethyl cellulose yog uniformly dispersed nyob rau hauv cov dej yam tsis muaj teeb meem loj lumps, thiab carboxymethyl cellulose thiab dej yuav statically nkag mus rau thiab fuse, lub stirring yuav tsum nres. Qhov sib tov ceev yog feem ntau ntawm 600-1300 rpm, thiab lub sij hawm stirring feem ntau yog tswj ntawm li 1 teev.
Kev txiav txim siab ntawm lub sijhawm xav tau rau kev ua tiav ntawm carboxymethyl cellulose yog raws li hauv qab no
1. Carboxymethyl cellulose thiab dej yog sib xyaw ua ke, thiab tsis muaj cov kua-kua sib cais ntawm ob.
2. Lub batter tom qab sib tov yog nyob rau hauv ib tug uniform lub xeev thiab nto yog du thiab du.
3. Cov xim ntawm cov khoom sib xyaw yog cov xim tsis muaj xim thiab pob tshab, thiab tsis muaj teeb meem granular nyob rau hauv paste. Nws yuav siv li ntawm 10 mus rau 20 teev kom muab cov carboxymethylcellulose tso rau hauv lub tank sib tov thiab sib tov nrog dej kom txog thaum carboxymethylcellulose yaj tag. Txhawm rau txhawm rau ua kom nrawm nrawm thiab txuag sijhawm, homogenizers lossis colloidal sib tsoo yog tam sim no siv los ua kom cov khoom tawg sai sai.
