Cov khoom siv gypsum, suav nrog cov plaster thiab cov khoom sib koom ua ke, tau txais txiaj ntsig los ntawm cov peev xwm khaws dej ntawm cellulose ethers. Qhov no txhim kho kev ua haujlwm thiab ntev lub sijhawm teeb tsa, ua rau kev siv thiab kev ua tiav zoo dua.
7. Kev ruaj khov ntawm emulsion hauv coatings:
Hauv cov txheej txheem txheej txheem dej, cellulose ethers ua haujlwm los tswj cov emulsions. Qhov kev ua kom ruaj khov no pab txhim kho qhov zoo ntawm cov txheej txheem, tiv thaiv kev sib cais theem thiab ua kom muaj kev siv khoom sib xws.
8. Txhim kho kev ua tau zoo ntawm cov tshuaj sib xyaw ua ke:
Cov tshuaj sib xyaw ua ke uas ua rau nws tus kheej sib npaug yog siv los ua kom qhov chaw du thiab tiaj tus. Cov cellulose ethers raug ntxiv rau cov tshuaj no los txhim kho lawv cov khoom los ntawm kev txhim kho kev ntws, txo qhov ntsws thiab xyuas kom meej tias qhov chaw tiav zoo ib yam.
9. Txo qhov ntsws ntawm plaster:
Cov stucco feem ntau ntsws thaum lub sijhawm ziab, ua rau muaj kab nrib pleb. Cellulose ethers pab txo qhov teeb meem no los ntawm kev txo qhov ntsws tag nrho ntawm cov khoom siv plaster, ua rau muaj qhov chaw ruaj khov thiab ruaj khov dua.
10. Cov ntaub ntawv siv rau kev tsim kho ntsuab:
Thaum kev lag luam kev tsim kho tau tsom mus rau kev ruaj khov, cellulose ethers pab txhawb rau kev tsim cov khoom siv hauv tsev ntsuab. Lawv cov khoom lwj tau yog raws li cov kev coj ua hauv kev tsim kho uas zoo rau ib puag ncig, ua rau lawv yog thawj qhov kev xaiv rau kev daws teeb meem kev tsim kho kom ruaj khov.
11. Hluav taws kub ntawm txheej:
Cov cellulose ethers tuaj yeem muab tso rau hauv cov txheej txheej kom txhim kho kev tiv thaiv hluav taws. Qhov no tseem ceeb heev rau cov ntawv thov uas qhov kev tiv thaiv hluav taws yog qhov tseem ceeb, xws li kev tsim kho sab nraud thiab cov ntaub ntawv tiv thaiv hluav taws.
12. Txhim kho kev ua tau zoo ntawm cov fiber cement:
Cov khoom siv fiber cement, suav nrog siding thiab board, tau txais txiaj ntsig los ntawm kev ntxiv cov cellulose ethers. Cov polymers no txhim kho kev ua tau zoo ntawm fiber cement los ntawm kev txhim kho kev nplaum, kev tiv thaiv dej thiab kev ruaj khov.
13. Txhim kho qhov kev nqus tau ntawm cov pob zeb sib xyaw ua tiav:
Hauv kev lag luam ua cov pob zeb sib xyaw ua ke, cov cellulose ethers pab txhim kho qhov kev nqus tau ntawm cov pob zeb sib xyaw. Qhov no yog qhov tseem ceeb rau kev thauj mus los thiab kev tso cov pob zeb hauv cov haujlwm tsim kho nrog ntau yam kev xav tau ntawm cov qauv.
14. Cov ntawv thov tshiab ntawm 3D luam ntawv:
Kev lag luam kev tsim kho tab tom tshawb nrhiav cov thev naus laus zis tshiab xws li 3D luam ntawv ntawm cov khoom siv hauv tsev.
