Ethyl Hydroxyethyl Cellulose (EHEC) hauv Daim Ntawv Txheej Xim

Ethyl hydroxyethyl cellulose (EHEC) yog cov dej-soluble polymer uas feem ntau siv hauv kev lag luam ntawv ua cov kev pab khaws cia thiab cov dej ntws. Nws yog feem ntau ntxiv rau lub pulp thaum lub sij hawm papermaking txheej txheem los txhim kho qhov tuav ntawm fillers thiab fibers thiab kom cov kua dej nce. EHEC tseem tuaj yeem siv rau hauv cov ntawv txheej xim los txhim kho kev ua haujlwm ntawm cov txheej txheem thiab txhim kho qhov zoo ntawm cov khoom kawg.

Daim ntawv txheej xim yog cov qauv uas siv rau hauv daim ntawv los txhim kho nws cov khoom nto, xws li ci, smoothness, gloss, thiab printability. Cov xim txheej feem ntau yog sib xyaw ntawm cov xim, cov hlua khi, cov khoom ntim, thiab cov khoom ntxiv uas tau tawg hauv dej los tsim cov slurry. Tom qab ntawd cov slurry yog siv rau hauv daim ntawv siv ntau yam txheej txheem txheej, xws li cov hniav txheej, txheej pas nrig, lossis cua riam txheej.

EHEC feem ntau yog siv los ua cov ntawv khi rau hauv cov ntawv txheej xim los txhim kho lawv cov adhesion rau daim ntawv thiab ua kom lawv lub zog thiab ua haujlwm ntev. Nws kuj yog siv los ua cov thickener los txhim kho cov viscosity thiab stability ntawm cov xim txheej, uas tuaj yeem pab txo qhov tshwm sim ntawm qhov tsis xws luag xws li streaks, pinholes, thiab txheej voids. EHEC tseem tuaj yeem txhim kho qhov gloss thiab smoothness ntawm daim ntawv coated nto, uas tuaj yeem txhim kho qhov luam tawm thiab pom qhov pom ntawm cov khoom kawg.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv EHEC hauv cov ntawv txheej xim yog nws lub peev xwm los tsim cov yeeb yaj kiab uas muaj zog, hloov tau yooj yim uas tuaj yeem tiv taus cov kev ntxhov siab ntawm cov txheej txheem papermaking thiab nruj ntawm kev tuav, kev xa khoom, thiab kev cia khoom. EHEC tseem tuaj yeem txhim kho cov dej tsis kam thiab cov cwj mem nqus cov khoom ntawm cov txheej, uas tuaj yeem txhim kho qhov zoo thiab ua haujlwm ntev ntawm cov duab luam tawm.

Lwm qhov kom zoo dua ntawm kev siv EHEC hauv cov ntawv txheej xim yog nws kev sib raug zoo nrog lwm cov khoom xyaw uas feem ntau siv hauv txheej txheej. EHEC tuaj yeem yooj yim muab tso rau hauv cov txheej txheem xim xim yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lwm cov khoom xyaw xws li pigments, fillers, thiab dispersants. EHEC kuj tseem tuaj yeem siv ua ke nrog lwm cov khoom sib khi, xws li styrene-butadiene latex (SBL) thiab polyvinyl cawv (PVOH), los txhim kho kev ua haujlwm ntawm txheej.

ethyl hydroxyethyl cellulose (EHEC) yog ntau yam polymer uas tuaj yeem siv rau hauv cov ntawv txheej xim los txhim kho lawv cov kev ua tau zoo thiab txhim kho qhov zoo ntawm cov khoom kawg. EHEC tuaj yeem txhim kho qhov adhesion, lub zog, thiab ua haujlwm ntev ntawm cov txheej, nrog rau cov gloss, smoothness, thiab printability ntawm cov ntawv coated. Nws compatibility nrog rau lwm cov khoom xyaw uas feem ntau siv nyob rau hauv txheej formulations ua rau nws ib tug txaus nyiam kev xaiv rau daim ntawv manufacturers nrhiav los txhim kho kev ua tau zoo ntawm lawv cov xim txheej.
