Kev siv CMC hauv txheej txheej
CMC,sodium carboxymethyl cellulose, muaj ntau yam kev siv hauv kev lag luam coatings, feem ntau yog ua cov thickener, stabilizer, thiab kev pab ua zaj duab xis, ua lub luag haujlwm tseem ceeb hauv kev txhim kho txheej txheej. Hauv qab no yog cov ncauj lus kom ntxaws ntawm CMC cov ntawv thov hauv kev lag luam coatings:
1. Thickening nyhuv
CMC, dej-soluble natural polymer compound, tuaj yeem ua kom cov viscosity ntawm cov txheej txheem zoo thiab tswj lawv cov khoom rheological, ua cov txheej txheem smoother thiab yooj yim rau kev thov. Los ntawm kev tswj tus nqi ntawm CMC ntxiv, ib tus tuaj yeem kho qhov sib xws ntawm cov xim latex, yog li txhim kho lawv daim ntawv thov kev ua tau zoo, txo qis qis, txhim kho kev tsim kho kom zoo, thiab ua kom muaj txheej txheej.
2. Stabilizing nyhuv
Pigments thiab fillers nyob rau hauv coatings feem ntau yuav khom, ua rau txheej stratification. Qhov sib ntxiv ntawm CMC tuaj yeem txhim kho qhov ruaj khov ntawm cov txheej txheej, tiv thaiv kev sib haum xeeb ntawm cov xim thiab cov khoom ntim, thiab ua kom cov txheej txheej tsis sib xws thiab zoo ib yam thaum khaws cia thiab siv. Tshwj xeeb tshaj yog thaum lub sijhawm khaws cia ntev, CMC qhov kev ruaj khov yog qhov tseem ceeb tshwj xeeb. Lub network qauv tsim los ntawm CMC tuaj yeem tiv thaiv kev sib haum xeeb ntawm pigments thiab fillers, tswj cov dispersion thiab uniformity ntawm coatings.
3. Zaj duab xis-Forming Aid Effect
CMC ua lub luag haujlwm pabcuam hauv cov txheej txheem ua yeeb yaj kiab ntawm txheej txheej, ua rau cov txheej txheej txheej denser thiab smoother tom qab ziab. Qhov no tsis tsuas yog txhim kho cov tsos zoo ntawm cov txheej, xws li txo cov txhuam hniav thiab cov txiv kab ntxwv tev, tab sis kuj txhim kho cov txheej txheem hnav tsis kam, kev laus ua haujlwm, thiab dej tsis kam, yog li txuas ntxiv lub neej kev pab cuam ntawm txheej.
4. Kev ua haujlwm ib puag ncig
Nrog rau kev nce ntxiv hauv kev tiv thaiv ib puag ncig, cov txheej txheem dej raws li tau dhau los ua qhov tseem ceeb hauv kev ua lag luam.CMC, raws li ib puag ncig tus phooj ywg txheej additive, muaj tsis muaj teeb meem tshuaj thiab ua tau raws li lub teb chaws ib puag ncig tiv thaiv qauv. Kev siv CMC hauv cov txheej txheem tuaj yeem tsis tsuas yog txo cov ntsiab lus ntawm VOCs (volatile organic compounds) tab sis kuj txhim kho kev ua haujlwm ib puag ncig ntawm cov txheej txheej, ua kom tau raws li cov kev xav tau ntawm kev tsim kho kom ruaj khov ntawm lub neej niaj hnub no.
5. Kev siv dav dav
CMC tsis yog tsuas yog haum rau cov xim latex thiab cov dej-raws li txheej, tab sis kuj yog rau cov txheej txheem tshwj xeeb xws li automotive coatings, marine coatings, food-grade coatings, and medical coatings. Hauv cov teb no, CMC tuaj yeem txhim kho qhov ua haujlwm ntev thiab kev tiv thaiv corrosion ntawm cov txheej txheem, ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov khoom.
Hauv cov ntsiab lus, CMC muaj dav daim ntawv thov kev cia siab thiab daim ntawv thov tseem ceeb hauv kev lag luam coatings. Nws tsis tsuas yog txhim kho kev ua tau zoo thiab cov txheej txheem zoo, tab sis kuj ua tau raws li cov neeg niaj hnub xav tau rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam coatings, CMC yuav tsis xav tsis thoob ua lub luag haujlwm tseem ceeb hauv kev ua lag luam yav tom ntej.
