Tolidine diisocyanate TODI / 3,3′-Dimethyl-4,4′-biphenylene diisocyanate CAS NO. 91-97-4
TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, nomoro ea CAS 91-97-4, ke tlatsetso ea bokahohleng bakeng sa ho ntlafatsa thepa ea mechini le ea lik'hemik'hale ho li-elastomer tsa urethane. Masale a mabeli a benzene molek'huleng ea TODI a na le sebopeho se lekanang. Ka lebaka la tšitiso ea steric ea sehlopha sa o-methyl, ts'ebetso ea karabelo e tlase ho feta ea TDI le MDI.
Ha ho bapisoa le li-elastomer tsa polyurethane tse thehiloeng ho NDI, li-elastomer tse thehiloeng ho TODI, li-polyol tsa oligomer le MOCA li na le thepa e tšoanang ea 'mele, joalo ka ho hanyetsa mocheso hantle, ho hanyetsa hydrolysis le thepa ea mechini. Ha li bapisoa le li-rabara, polasetiki le litšepe, li-elastomer tse thehiloeng ho TODI li na le melemo e mengata haholo, lia tšoarella, li hanyetsa mocheso le ho hanyetsa hydrolysis. Li-elastomer tse thehiloeng ho TODI li fana ka thepa e phahameng ea mechini e ka sebelisoang ha ho sebetsa tlas'a maemo a thata le/kapa tikoloho. Ho feta moo, ka lebaka la bophelo ba eona bo bolelele ba pitsa, prepolymer e thehiloeng ho TODI e bonolo ho e sebetsana ha e bapisoa le lihlahisoa tse thehiloeng ho NDI.
Ka thepa ea eona e ikhethang ea mechine le lik'hemik'hale, li-elastomer tse thehiloeng ho TODI li sebelisoa haholo masimong a fapaneng. Ntlha ea pele, likarolo tsa ho tiisa, tse kang ho tiisa oli, lesale la piston, litiiso tsa metsi le tse ling. Ebe, likarolo tsa koloi ke ts'ebeliso e 'ngoe e kholo ea TODI, ho kenyeletsoa le katoloso ea bumper, li-shock absorber, li-grill le tse ling. Ntle le moo, ts'ebeliso e phahameng ea indasteri, ke hore mabanta, lirolo, li-caster. Ho feta moo, TODI ke moemeli oa bohlokoa oa ho koahela tšimong ea motlakase le joalo ka litho tsa maiketsetso lisebelisoa tsa bongaka.
Pakete: 50kgs/moropa wa tshepe.
Polokelo le lipalangoang: TODI e utloa mongobo habonolo. Metsi a arabela le diisocyanate tsohle ho etsa di-derivatives tsa urea tse sa qhibiliheng. TODI e lokela ho bolokoa ka har'a lijana tse koetsoeng ka thata maemong a pholileng le a omileng.
U SE KE UA beha TODI hammoho le lijo 'me u qobe ho e pepesetsa tikolohong e kaholimo ho 30℃. Kamora ho e sebelisa, sekoahelo se tlameha ho koaloa hang-hang haeba ho se sebetse hantle. Tlas'a maemo a loketseng a polokelo, TODI e sebetsa likhoeli tse tšeletseng bonyane ho tloha ka letsatsi leo e tlisoang ka lona.
