Kev piav qhia txog khoom

TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, CAS tus lej 91-97-4, yog ib qho khoom siv thoob ntiaj teb rau kev txhim kho cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm urethane elastomers. Ob lub nplhaib benzene hauv TODI molecule muaj cov qauv sib npaug. Vim yog qhov kev cuam tshuam steric ntawm pawg o-methyl, qhov kev ua haujlwm ntawm cov tshuaj tiv thaiv qis dua li ntawm TDI thiab MDI.

Piv rau NDI-raws li polyurethane elastomers, elastomers raws li TODI, oligomer polyols thiab MOCA muaj cov khoom zoo sib xws, xws li kev tiv taus cua sov zoo heev, kev tiv taus hydrolysis thiab cov khoom siv kho tshuab. Piv nrog roj hmab, yas thiab hlau, TODI-raws li elastomers muaj ntau qhov zoo dua, lawv ruaj khov, tiv taus cua sov thiab kev tiv taus hydrolysis. TODI-raws li elastomers muaj cov khoom siv kho tshuab zoo dua los siv rau kev ua haujlwm hauv qab qhov xwm txheej hnyav thiab / lossis ib puag ncig. Ntxiv mus, vim nws lub neej ntev dua, TODI-raws li prepolymer yooj yim dua rau kev tuav piv rau NDI-raws li cov khoom.

Daim Ntawv Thov

Nrog nws cov khoom siv kho tshuab thiab tshuaj lom neeg zoo tshaj plaws, TODI-based elastomers tau siv dav hauv ntau qhov chaw. Ua ntej tshaj plaws, cov khoom sib khi, xws li roj sealing, piston ring, dej seals thiab lwm yam. Tom qab ntawd, cov khoom siv hauv tsheb yog lwm qhov kev siv loj ntawm TODI, suav nrog bumper extensions, shock absorbers, grills thiab lwm yam. Dhau li ntawm qhov ntawd, kev siv hauv kev lag luam siab, piv txwv li siv txoj siv sia, dov, casters. Ntxiv mus, TODI yog tus neeg sawv cev tseem ceeb hauv hluav taws xob thiab ua cov kab mob cuav hauv cov khoom siv kho mob.

Ntim Khoom & Khaws Cia

Ntim: 50kgs / hlau nruas.

Kev Khaws Cia thiab Kev Thauj Mus Los: TODI rhiab heev rau cov dej noo. Dej ua rau muaj kev cuam tshuam nrog txhua yam diisocyanates los tsim cov urea derivatives uas tsis yaj. TODI yuav tsum khaws cia rau hauv cov thawv kaw nruj nreem rau hauv qhov chaw txias thiab qhuav.

TSIS TXHOB muab TODI tso nrog zaub mov thiab tsis txhob muab tso rau hauv qhov chaw uas kub tshaj 30℃. Tom qab siv tas, yuav tsum kaw lub hau tam sim ntawd yog tias nws puas lawm. Yog tias khaws cia kom zoo, TODI yuav siv tau tsawg kawg yog rau lub hlis txij li hnub uas nws xa tuaj.
