1,2,3,4-Butanetetracarboxylic acid (BTCA) yog ib qho tshuaj pleev xim zoo meej uas tsis muaj formaldehyde thiab ruaj khov (DP). Nws muaj kev ua haujlwm siab thiab tsis muaj ntxhiab tsw phem. Ua los ntawm BTCA, cov ntaub xws li paj rwb thiab txhob lo lo ntxhuav tuaj yeem ua tiav cov yam ntxwv xws li tiv thaiv kev txiav, nias tas mus li thiab khaws cov duab thiab muaj lub zog siab.
BTCA siv tau los npaj cov ntaub ntawv polyimide. Hom khoom no muaj kev tiv taus kub zoo heev, tiv taus kua qaub, tiv taus hydrocarbon thiab cov khoom rwb thaiv hluav taws xob zoo, thiab siv tau los npaj ntau yam khoom siv polymer ua haujlwm, xws li cov ntaub ntawv photosensitive, cov ntaub ntawv polymer kho mob thiab cov ntaub ntawv polymer membrane ua haujlwm. Nws siv tau los npaj cov nplhaib rwb thaiv hluav taws xob, cov hlau txheej thiab cov ntaub ntawv rwb thaiv hluav taws xob.
25kg hnab ntawv sib xyaw Polish - linen bush lossis raws li cov neeg siv khoom xav tau.
Kev Khaws Cia:
Khaws cia kom ruaj khov rau hauv qhov chaw ntxoov ntxoo thiab cua nkag tau. Nws lub sijhawm khaws cia yog 12 lub hlis. Nws tseem siv tau yog tias nws siv ntev dua.
Kev Thauj Mus Los:
Tsis txhob cia kub thiab kub hnyiab thaum lub sijhawm thauj mus los.
