TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, nọmba CAS 91-97-4, bụ ihe mgbakwunye zuru ụwa ọnụ maka imeziwanye akụrụngwa na kemịkalụ na urethane elastomers. Mgbaaka benzene abụọ dị na molekul TODI nwere nhazi symmetrical. N'ihi mgbochi steric nke otu o-methyl, ọrụ mmeghachi omume dị ala karịa nke TDI na MDI.

N'iji ya tụnyere polyurethane elastomers nke dabeere na NDI, elastomers nke dabere na TODI, oligomer polyols na MOCA nwere ihe ndị yiri ya, dịka ezigbo iguzogide okpomọkụ, iguzogide hydrolysis na ihe ndị yiri ya. Ma e jiri ya tụnyere roba, plastik na ọla, elastomers nke dabere na TODI nwere ọtụtụ uru karịa, ha na-adịgide adịgide, na-eguzogide okpomọkụ na iguzogide hydrolysis. Elastomers nke dabere na TODI na-enye ihe ndị dị elu maka igwe iji rụọ ọrụ n'okpuru ọnọdụ siri ike na/ma ọ bụ gburugburu ebe obibi. Ọzọkwa, site na ndụ ite ya dị ogologo, prepolymer nke dabere na TODI dị mfe ijikwa ma e jiri ya tụnyere ngwaahịa dabere na NDI.

Ngwa

Site na njirimara igwe na kemịkalụ pụrụ iche ya, a na-etinye elastomers dabere na TODI n'ọtụtụ ebe. Nke mbụ, ihe ndị e ji mechie ihe, dị ka mkpuchi mmanụ, mgbanaka piston, mkpuchi mmiri na ihe ndị ọzọ. Mgbe ahụ, akụkụ ụgbọala bụ ngwa ọzọ dị mkpa nke TODI, gụnyere ndọtị bamper, ihe na-amịkọrọ ihe mberede, ihe e ji esi nri na ihe ndị ọzọ. E wezụga nke ahụ, ojiji ụlọ ọrụ mmepụta ihe dị elu, ya bụ, eriri, mpịakọta, ihe e ji agbanye ihe. Ọzọkwa, TODI bụ ihe mkpuchi dị mkpa na mpaghara eletriki na dị ka akụkụ ahụ e ji arụ ọrụ na ngwa ahụike.

Nkwakọba na Nchekwa

Nkwakọba: 50kgs/mkpọm ígwè.

Nchekwa na Njem: TODI na-enwe mmetụta mmiri. Mmiri na-emeghachi omume na diisocyanates niile iji mepụta ihe ndị sitere na urea na-anaghị agbaze. A ga-echekwa TODI n'ime akpa mechiri emechi n'ọnọdụ oyi na akọrọ.

Etinyela TODI na nri ma zere ikpughe ya n'ebe okpomọkụ karịrị 30℃. Mgbe ejiri ya, a ga-emechi mkpuchi ahụ ozugbo ma ọ bụrụ na nsogbu adịghị. N'ọnọdụ nchekwa kwesịrị ekwesị, TODI dị irè ruo ọnwa isii ma ọ dịkarịa ala malite n'ụbọchị e nyere ya.
