Cellulose ethers yog cov polymers tseem ceeb tshaj plaws hauv kev tsim kho. Nws lub peev xwm los ua tus hloov kho rheology ua rau nws muaj kev xaiv nrov rau cov ntawv nplaum nplaum. Pobzeb nplaum yog ib qho tseem ceeb ntawm cov txheej txheem tsim kho vim nws pab kom ruaj ntseg pobzeb rau phab ntsa, pem teb thiab lwm qhov chaw. Hauv tsab xov xwm no, peb tham txog cov txiaj ntsig ntawm kev siv cellulose ethers hauv cov nplais nplaum.
Txhim kho kev ua haujlwm
Qhov sib ntxiv ntawm cellulose ethers rau cov nplais nplaum nplaum tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom sib tov. Kev ua haujlwm tau hais txog qhov yooj yim uas cov nplaum tuaj yeem kis tau thoob plaws ib puag ncig thiab ua haujlwm rau hauv qhov chaw. Cellulose ether ua raws li kev hloov kho rheology, txhais tau tias nws tuaj yeem cuam tshuam rau lub cev ntawm cov nplaum. Los ntawm kev kho cov rheology ntawm cov nplaum, cellulose ethers tuaj yeem txhim kho nws cov txheej txheem, ua kom yooj yim rau kev siv cov nplaum sib npaug thiab tsis tu ncua.
txhim khu kev tuav dej
Cellulose ether yog hydrophilic, uas txhais tau hais tias nws muaj zog affinity rau dej. Thaum ntxiv rau cov nplais nplaum, cellulose ethers tuaj yeem txhim kho cov dej tuav cov khoom ntawm cov qauv. Qhov no yog ib qho tseem ceeb vim tias cov nplais nplaum xav tau ib qho dej los kho kom zoo. Los ntawm kev txhim kho cov dej tuav cov khoom ntawm cov nplaum, cellulose ethers ua rau nws muaj peev xwm kho tau, ua rau muaj kev sib raug zoo ntawm cov pobzeb thiab saum npoo.
Txhim kho daim ntawv cog lus zog
Cellulose ether kuj tseem tuaj yeem txhim kho lub zog ntawm cov pobzeb nplaum. Lub zog ntawm daim nplaum yog nyob ntawm ntau yam, nrog rau hom substrate, hom pobzeb, thiab kho cov mob. Los ntawm kev sib koom ua ke ntawm cellulose ether rau hauv daim ntawv nplaum, daim ntawv cog lus lub zog ntawm cov nplaum tuaj yeem nce ntxiv. Qhov no yog vim cellulose ether pab xyuas kom meej tias cov nplaum kho tusyees thiab tsis muaj qhov tsis muaj zog hauv daim ntawv cog lus.
Txhim kho cov sijhawm qhib
Lub sijhawm qhib yog lub sijhawm uas cov nplaum tuaj yeem ua haujlwm tau tom qab nws tau siv rau qhov chaw. Lub sijhawm qhib ntev dua, lub sijhawm ntev dua tus neeg nruab yuav tau kho cov pobzeb ua ntej cov nplaum kho. Ntxiv cov cellulose ethers rau cov nplais nplaum tuaj yeem txuas ntxiv lawv lub sijhawm qhib, muab cov neeg ua haujlwm yooj yim dua thiab tso cai rau lawv ua haujlwm tau zoo dua.
Txhim kho plam tsis kam
Slip resistance yog ib qho tseem ceeb uas yuav tau xav txog thaum xaiv cov nplaum nplaum. Cov vuas yuav tsum muaj kev ruaj ntseg thiab ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj kev ya raws los yog kev khiav tsheb siab. Cellulose ethers tuaj yeem pab txhim kho kev ua haujlwm tsis zoo ntawm cov nplais nplaum los ntawm kev ua kom lawv cov viscosity. Tackier adhesives tsis tshua muaj plam lossis swb, muab cov pobzeb muaj zog, ruaj khov dua.
nyob rau hauv xaus
Hauv cov ntsiab lus, cellulose ethers yog ib feem tseem ceeb ntawm cov nplais nplaum nplaum. Nws txhim khu kev ua haujlwm, dej tuav, ruaj khov, lub sijhawm qhib thiab ua haujlwm tsis zoo, ua rau nws zoo tagnrho rau kev siv vaj tsev. Los ntawm kev siv cellulose ethers hauv cov nplais nplaum, cov neeg tsim khoom tuaj yeem ua kom lawv cov vuas yog sib koom ua ke kom ruaj ntseg thiab lawv cov haujlwm tsim kho tau ua tiav zoo thiab ua tau zoo. Zuag qhia tag nrho, kev siv cov cellulose ethers qhia txog kev ua haujlwm zoo los txhim kho cov kev coj ua hauv tsev thiab ua kom cov kav ntev thiab ntev ntawm cov khoom tsim.
