Dab tsi yog qhov tsawg kawg nkaus ua kom muaj qhov kub thiab txias (MFT) ntawm redispersible polymer hmoov?

Kima Chemical tuaj yeem muab qee cov ntaub ntawv dav dav ntawm MFT thiab nws qhov tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv rov ua dua tshiab polymer hmoov.

MFT yog qhov kub thiab txias ntawm cov polymer dispersion tuaj yeem tsim cov yeeb yaj kiab txuas ntxiv thaum qhuav. Nws yog ib qho tseem ceeb ntawm qhov kev ua tau zoo ntawm cov khoom siv rov ua dua tshiab ntawm cov hmoov polymer vim tias nws cuam tshuam rau lub peev xwm ntawm cov hmoov los ua ib zaj duab xis cohesive thiab txuas ntxiv ntawm cov substrate.

MFT ntawm redispersible polymer hmoov sib txawv nyob ntawm seb hom polymer, qhov loj me, thiab cov tshuaj muaj pes tsawg leeg. Feem ntau, redispersible polymer hmoov muaj MFT ntau ntawm 0 ° C txog 10 ° C. Txawm li cas los xij, qee cov polymers yuav muaj MFT tsawg li -10 ° C lossis siab li 20 ° C.

Feem ntau, MFT qis dua yog qhov xav tau rau cov khoom siv rov ua dua tshiab polymer hmoov vim nws tso cai rau kev tsim cov yeeb yaj kiab zoo dua ntawm qhov kub thiab txias, uas tuaj yeem ua rau txhim kho adhesion, yooj, thiab ua haujlwm ntev ntawm cov txheej. Txawm li cas los xij, MFT yuav tsum tsis txhob qis dhau vim nws tuaj yeem ua rau cov dej tsis zoo thiab cov yeeb yaj kiab ncaj ncees.

Hauv kev xaus, MFT ntawm redispersible polymer hmoov yog ib qho tseem ceeb parameter uas cuam tshuam rau kev ua tau zoo ntawm txheej. Qhov zoo tshaj plaws MFT yog nyob ntawm cov kev thov tshwj xeeb thiab cov khoom siv polymer.
