Tolidine diisocyanate TODI / 3,3′-Dimethyl-4,4′-biphenylene diisocyanate CAS NO. 91-97-4 ib
TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, CAS naj npawb 91-97-4, yog ib tug universal additive rau kev txhim kho txhua yam thiab tshuaj zog ntawm urethane elastomers. Ob lub nplhaib benzene nyob rau hauv TODI molecule muaj ib tug symmetrical qauv. Vim yog qhov steric hindrance ntawm pawg o-methyl, cov tshuaj tiv thaiv kev ua haujlwm qis dua li ntawm TDI thiab MDI.
Muab piv rau NDI-raws li polyurethane elastomers, elastomers raws li TODI, oligomer polyols thiab MOCA muaj cov khoom zoo sib xws, xws li kub tsis kam, hydrolysis tsis kam thiab txhua yam khoom. Muab piv nrog cov roj hmab, yas thiab hlau, TODI-raws li elastomers muaj ntau yam zoo, lawv muaj zog, kub tsis kam thiab hydrolysis tsis kam. TODI-raws li elastomers muab cov cuab yeej zoo tshaj plaws los siv rau kev ua haujlwm hauv cov xwm txheej hnyav thiab / lossis ib puag ncig. Tsis tas li ntawd, ua los ntawm nws lub lauj kaub ntev dua, TODI-raws li prepolymer yog yooj yim los tuav hauv kev sib piv rau NDI-based khoom.
Nrog nws cov khoom siv kho tshuab thiab tshuaj lom neeg zoo, TODI-based elastomers tau siv dav hauv ntau qhov chaw. Ua ntej ntawm tag nrho cov, sealing Cheebtsam, xws li roj sealing, piston nplhaib, dej ntsaws ruaj ruaj thiab lwm yam. Tom qab ntawd, cov khoom siv hauv tsheb yog lwm daim ntawv thov tseem ceeb ntawm TODI, suav nrog kev txuas ntxiv, kev poob siab, cov hniav nyiaj hniav kub thiab lwm yam. Tsis tas li ntawd, cov khoom siv high-end siv, xws li siv cov hlua, yob, casters. Tsis tas li ntawd, TODI yog cov txheej txheem tseem ceeb hauv hluav taws xob thiab ua cov khoom siv hauv nruab nrog cev hauv cov khoom siv kho mob.
Ntim: 50kgs / hlau nruas.
Kev khaws cia thiab kev thauj mus los: TODI rhiab rau cov dej noo. Dej reacts nrog tag nrho cov diisocyanates los tsim insoluble urea derivatives. TODI yuav tsum tau muab khaws cia rau hauv cov thawv kaw ntom ntom hauv qhov txias thiab qhuav.
Tsis txhob muab TODI nrog rau cov zaub mov thiab tsis txhob nthuav tawm hauv ib puag ncig siab tshaj 30 ℃. Tom qab siv, lub hau yuav tsum tau muab kaw tam sim ntawd thaum muaj kev ua haujlwm tsis zoo. Raws li qhov tsim nyog khaws cia, TODI siv tau rau rau lub hlis tsawg kawg nrog cov txiaj ntsig txij li hnub uas nws tau xa tuaj.
