Dawb crystals orwhite crystalline hmoov, soluble nyob rau hauv dej, cawv thiab lwm yam organic solvent.Nws cov kua aqueous yog acidic.
1,2,3,4-Butanetetracarboxylic acid (BTCA) yog ib qho zoo tshaj plaws formaldehyde-dawb check xovxwm (DP) xov tooj. Nws muaj kev ua haujlwm siab ntawm cov tshuaj tiv thaiv thiab tsis muaj ntxhiab tsw ntxhiab. Ua tiav los ntawm BTCA, fabrics xws li paj rwb thiab txhob lo lo ntxhuav muaj peev xwm ua tiav cov khoom xws li kev tiv thaiv tsis tu ncua, xovxwm ruaj khov thiab ua kom zoo thiab muaj lub siab tawv.
BTCA tuaj yeem siv los npaj cov ntaub ntawv polyimide. Cov ntaub ntawv zoo li no muaj kev tiv thaiv kub zoo, acid tsis kam, hydrocarbon tsis kam thiab hluav taws xob rwb thaiv tsev zoo, thiab tuaj yeem siv los npaj ntau yam khoom siv polymer, xws li cov ntaub ntawv photosensitive, cov ntaub ntawv kho mob polymer thiab cov khoom siv polymer membrane. Nws tuaj yeem siv los npaj cov hluav taws xob rwb thaiv tsev rings, hlau coatings thiab cov khoom siv hluav taws xob rwb thaiv tsev.
25kg composite ntawv hnab Polish - linen hav txwv yeem lossis raws li cov neeg siv khoom xav tau.
