Pobzeb adhesives yog dab tsi?

Pobzeb nplaum yog ib hom khoom siv los khi cov vuas rau saum npoo ntawm lub substrate, xws li phab ntsa lossis hauv pem teb.Nws yog kev sib xyaw ntawm cov cement, xuab zeb, thiab lwm yam additives xws li cellulose ether.

Cellulose ether yog dej-soluble polymer muab los ntawm ntuj cellulose.Nws yog dav siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug thickener, stabilizer, binder, thiab dej retention agent.Nyob rau hauv cov ntaub ntawv ntawm cov pobzeb nplaum, cellulose ether yog ntxiv rau qhov sib tov los muab kev txhim kho kev ua haujlwm thiab dej tuav cov khoom.

Ib qho ntawm lub luag haujlwm tseem ceeb ntawm cellulose ether hauv cov nplaum nplaum yog nws lub peev xwm los ua kom cov sib tov sib xyaw.Cov nplaum nplaum yuav tsum yog tuab txaus los tuav cov vuas kom ruaj khov rau hauv qhov chaw tab sis nyias txaus kom yooj yim kis tau los ntawm qhov chaw.Cellulose ether pab kom ua tiav txoj cai sib xws los ntawm thickening cov sib tov, ua kom yooj yim rau kis tusyees saum npoo.

Lwm qhov tseem ceeb ntawm cellulose ether hauv cov nplaum nplaum yog nws lub peev xwm khaws dej.Pobzeb nplaum yuav tsum nyob twj ywm rau qee lub sijhawm los xyuas kom meej adhesion kom zoo thiab tiv thaiv kev tawg lossis shrinkage.Cellulose ether pab khaws cov dej hauv qhov sib tov, uas ua rau cov txheej txheem kom qhuav thiab ua kom cov nplaum ua kom zoo.

Cellulose ether kuj ua raws li cov ntaub ntawv hauv cov pobzeb nplaum, pab tuav cov sib tov ua ke thiab txhim kho nws cov adhesion rau saum npoo.Qhov no ua kom ntseeg tau tias cov vuas tsim ib qho kev sib raug zoo nrog rau saum npoo, tsim kom muaj kev ruaj khov thiab kav ntev.

Qhov zoo thiab kev ua tau zoo ntawm cov pobzeb nplaum tau cuam tshuam los ntawm hom thiab tus nqi ntawm cellulose ether siv.Muaj ntau hom cellulose ether muaj nyob hauv khw, xws li hydroxyethyl cellulose (HEC), methyl cellulose (MC), thiab carboxymethyl cellulose (CMC).Txhua hom muaj cov khoom sib txawv thiab cov yam ntxwv, thiab xaiv hom thiab tus nqi yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo ntawm cov nplais nplaum.

Hauv cov ntsiab lus, cellulose ether plays lub luag haujlwm tseem ceeb hauv kev tsim cov nplais nplaum.Nws muab qhov tsim nyog thickening, khi, thiab dej tuav cov khoom rau qhov sib tov, uas ua kom nws ua haujlwm tau zoo, txhim kho adhesion, thiab tiv thaiv kev tawg lossis shrinkage.Kev xaiv hom thiab tus nqi ntawm cellulose ether yog qhov tseem ceeb hauv kev tsim cov nplais nplaum nplaum uas ua tau raws li cov qauv xav tau ntawm kev tsim kho kev lag luam.
