Kev siv Cellulose Ethers hauv Ntawv Kev Lag Luam

Cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawv, pab tsim ntau yam ntawv thiab cov khoom siv ntawv.Nov yog qee qhov kev siv ntawm cellulose ethers hauv qhov haujlwm no:

1. Surface Sizing: Cellulose ethers yog siv los ua tus neeg saib xyuas qhov loj me hauv daim ntawv los txhim kho cov khoom saum npoo ntawm daim ntawv thiab txhim kho nws cov luam ntawv, smoothness, thiab number case adhesion.Lawv tsim cov txheej nyias nyias ntawm cov ntawv sau, txo cov porosity saum npoo, tiv thaiv cov xim feathering, thiab txhim kho xim vibrancy.
2. Internal Sizing: Cellulose ethers ua raws li cov neeg sawv cev hauv cov ntaub ntawv los txhim kho cov dej tsis kam thiab qhov ntev ntawm cov khoom siv.Lawv nkag mus rau hauv daim ntawv fibers thaum lub sij hawm ntub-kawg txheej txheem, tsim ib tug hydrophobic barrier uas txo cov dej nqus dej thiab ua rau kom tsis kam mus rau noo noo, av noo, thiab kua nkag.
3. Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Tiv Thaiv Dej: Cellulose ethers ua haujlwm khaws cia thiab tso dej hauv cov ntaub ntawv los txhim kho cov ntaub so ntswg, fiber ntau flocculation, thiab cov dej ntws tawm ntawm lub tshuab ntawv.Lawv txhim khu kev tsim thiab sib xws ntawm cov ntawv ntawv, txo cov nqi nplua thiab cov fillers poob, thiab ua kom lub tshuab khiav tau zoo thiab tsim khoom.
4. Tsim thiab Txhim Kho Lub Zog: Cellulose ethers pab txhawb kev tsim thiab lub zog ntawm cov khoom siv los ntawm kev txhim kho fiber ntau bonding, interfiber bonding, thiab daim ntawv consolidation.Lawv txhim khu kev sib raug zoo thiab tensile lub zog ntawm daim ntawv, txo cov kua muag, tawg, thiab linting thaum tuav thiab hloov cov txheej txheem.
5. Txheej thiab khi: Cellulose ethers yog siv los ua cov ntawv khi thiab cov txheej txheem ntxiv rau hauv cov ntawv txheej thiab kev kho saum npoo los txhim kho adhesion, npog, thiab gloss.Lawv txhim khu kev khi ntawm pigments, fillers, thiab additives rau daim ntawv nto, muab smoothness, brightness, thiab luam ntawv zoo.
6. Functional Additives: Cellulose ethers ua cov khoom siv ntxiv rau hauv cov ntawv tshwj xeeb thiab cov khoom siv los ua cov khoom tshwj xeeb xws li lub zog ntub dej, lub zog qhuav, roj tsis kam, thiab cov khoom thaiv.Lawv txhim khu kev ua tau zoo thiab ua haujlwm ntev ntawm cov khoom siv hauv cov ntawv siv ntau yam xws li ntim, ntawv, lim, thiab cov ntaub ntawv kho mob.
7. Recycling Aid: Cellulose ethers pab txhawb kev rov ua dua ntawm cov ntawv thiab cov khoom siv los ntawm kev txhim kho fiber ntau dispersion, pulp ncua kev kawm ntawv, thiab number case detachment thaum lub sij hawm repulping thiab deinking txheej txheem.Lawv pab txo qis fiber ntau, txhim kho cov kua txiv hmab txiv ntoo, thiab txhim kho cov khoom siv ntawv zoo.

cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawv los ntawm kev txhim kho qhov zoo, kev ua tau zoo, thiab kev ruaj khov ntawm cov ntawv thiab cov khoom siv ntawv.Lawv versatility, compatibility, thiab ib puag ncig tus phooj ywg xwm ua rau lawv muaj txiaj ntsig additives rau optimizing papermaking txheej txheem thiab ua tau raws li cov kev xav tau ntawm kev lag luam ntawv.
