Incazelo Yomkhiqizo

I-TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, inombolo ye-CAS 91-97-4, iyisengezo somhlaba wonke sokuthuthukisa izakhiwo zemishini namakhemikhali kuma-urethane elastomers. Amasongo amabili e-benzene ku-molecule ye-TODI anokwakheka okulinganayo. Ngenxa yesithiyo esiqinile seqembu le-o-methyl, umsebenzi wokusabela uphansi kunalowo we-TDI ne-MDI.

Uma kuqhathaniswa ne-NDI-based polyurethane elastomers, ama-elastomers asekelwe ku-TODI, i-oligomer polyols ne-MOCA anezinto ezibonakalayo ezifanayo, ezifana nokumelana nokushisa okuhle kakhulu, ukumelana ne-hydrolysis kanye nezakhiwo zemishini. Uma kuqhathaniswa namarabha, amapulasitiki nezinsimbi, ama-elastomers asekelwe ku-TODI anezinzuzo eziningi kakhulu, aqinile, ukumelana nokushisa nokumelana ne-hydrolysis. Ama-elastomer asuselwa ku-TODI anikezela ngezakhiwo ezisezingeni eliphezulu okufanele zisetshenziswe ekusebenzeni ngaphansi kwezimo ezinzima kanye/noma imvelo. Ngaphezu kwalokho, ngenxa yokuphila kwayo okude kwebhodwe, i-prepolymer esekwe ku-TODI kulula ukuyiphatha uma kuqhathaniswa nemikhiqizo esekwe ku-NDI.

Isicelo

Ngezakhiwo zayo ezivelele zemishini namakhemikhali, ama-elastomer asekelwe ku-TODI asetshenziswa kabanzi emikhakheni ehlukahlukene. Okokuqala, izingxenye zokuvala, njengokuvalwa kwamafutha, indandatho ye-piston, izimpawu zamanzi nokunye. Khona-ke, izingxenye zezimoto zingolunye uhlelo lokusebenza oluyinhloko lwe-TODI, okuhlanganisa izandiso ze-bumper, i-shock absorbers, ama-grill nokunye. Ngaphezu kwalokho, i-TODI iyi-ejenti yokuhlanganisa ebalulekile emkhakheni kagesi nanjengezitho zokwenziwa emishinini yezokwelapha.

Ukupakisha & Isitoreji

Ukupakisha: 50kgs/isigubhu sensimbi.

Isitoreji kanye nezinto zokuhamba: I-TODI izwela umswakama. Amanzi ahlangana nawo wonke ama-disocyanate akhe okuphuma kokuphuma kwe-urea engancibiliki. I-TODI kufanele igcinwe ezitsheni ezivalwe ngokuqinile ezimweni ezipholile nezomile.

UNGAYIfaki i-TODI kanye nokudla futhi ugweme ukuvezwa endaweni engaphezu kuka-30 ℃. Ngemuva kokusetshenziswa, isivalo kufanele sivalwe ngokushesha uma kwenzeka ukungasebenzi kahle. Ngaphansi kwezimo ezifanele zokulondoloza, i-TODI isebenza izinyanga eziyisithupha okungenani kusukela ngedethi edilivwe ngayo.
