Nws tuaj yeem txhim kho cov nyhuv tuav dej los ntawm kev tswj thiab kho cov rheology ntawm txheej. Nws tuaj yeem ua kom pom kev ua kom zoo dua qub thiab ua kom lub ntsej muag zoo dua li cov hmoov txhuv nplej siab, polyethylene glycol thiab lwm cov fluorescent brightening tus neeg sawv cev, nws yog ib daim ntawv ua ntau yam kev pab.
MLub luag haujlwm ntawm CMC hauv kev lag luam ntawv:
1. Xim txheej
Tswj thiab kho cov rheology ntawm cov xim thiab pigment dispersion, txhim kho cov ntsiab lus ntawm cov xim;
Ua kom cov txheej txheem muaj cov yas cuav, txhim kho cov txheej txheem ceev;
Txhim kho txheej dej tuav, tiv thaiv dej-soluble nplaum tsiv teb tsaws;
Muaj kev ua yeeb yaj kiab zoo, txhim kho cov gloss ntawm txheej;
Txhim kho tus nqi khaws cia ntawm tus neeg sawv cev whitening hauv txheej, txhim kho cov ntawv dawb;
Txhim kho lub lubrication kev ua tau zoo ntawm txheej, txhim kho qhov zoo ntawm txheej, ncua lub neej kev pab cuam ntawm lub scraper.
2. Ntxiv rau hauv slurry
Txhim kho kev sib tsoo efficiency, txhawb fiber ntau refinement, shorten beating lub sij hawm;
Kho cov hluav taws xob muaj peev xwm hauv cov ntaub so ntswg, sib npaug ntawm cov fiber ntau, txhim kho "kev ua tau zoo" ntawm lub tshuab ntawv, thiab txhim kho cov nplooj ntawv ntxiv;
Txhim kho qhov tuav ntawm ntau yam additives, fillers thiab nplua fibers;
Ua kom lub zog khi ntawm fibers, txhim kho lub cev ntawm daim ntawv;
Lub zog qhuav thiab ntub ntawm daim ntawv tuaj yeem txhim kho thaum siv ua ke nrog tus neeg sawv cev qhuav thiab ntub dej.
Tiv thaiv rosin, AKD thiab lwm yam sizing tus neeg sawv cev, txhim khu sizing nyhuv.
3. Qhov loj me
Nws muaj cov cuab yeej zoo rheological thiab zaj duab xis tsim cov cuab yeej.
Txo daim ntawv nto pores, txhim kho cov roj tsis kam ntawm daim ntawv;
Ua kom qhov ci thiab ci ntawm daim ntawv;
Ua kom cov ntawv nruj, smoothness, tswj crimp;
Ua kom lub zog saum npoo thiab hnav tsis kam ntawm daim ntawv, txo cov plaub hau thiab hmoov, txhim kho kev luam ntawv zoo.

Daim ntawv thov
Hauv kev lag luam ntawv, CMC yog siv rau hauv cov txheej txheem pulping, uas tuaj yeem txhim kho tus nqi tuav thiab ua kom muaj zog ntub dej. Siv rau saum npoo sizing, raws li ib tug pigment excipient, txhim kho nrog adhesion, txo cov plua plav luam ntawv, txhim kho luam ntawv zoo; Siv rau cov ntawv txheej, yog qhov zoo rau dispersion thiab fluidity ntawm cov xim, txhim khu cov ntawv smoothness, smoothness, optical zog thiab luam ntawv adaptability. Nyob rau hauv daim ntawv kev lag luam raws li ib tug tsim nyog tus nqi thiab ntau yam additives, feem ntau yog vim nws cov dej-soluble polymer zaj duab xis tsim thiab roj kuj.
Siv rau cov ntawv sizing, yog li ntawd cov ntawv muaj qhov siab, zoo nkauj permeability tiv taus, sau ntawv siab thiab smoothness.
● Muaj peev xwm txhim kho daim ntawv sab hauv fiber ntau viscosity xeev, txhawm rau txhim kho daim ntawv lub zog thiab folding kuj.
● Nyob rau hauv daim ntawv thiab daim ntawv xim txheej txheem, CMC pab tswj cov ndlwg ntawm cov xim muab tshuaj txhuam thiab nqus tus number case zoo.
Feem ntau, cov tshuaj pom zoo yog 0.3-1.5%.
Ntim:
CMC Khoom yog ntim rau hauv peb txheej hnab ntawv nrog lub hnab polyethylene inner, net hnyav yog 25kg ib lub hnab.
