Incazelo Yomkhiqizo

I-TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, inombolo ye-CAS 91-97-4, iyisengezo esijwayelekile sokuthuthukisa izakhiwo zemishini nezamakhemikhali kuma-elastomer e-urethane. Amasongo amabili e-benzene ku-molecule ye-TODI anesakhiwo esilinganayo. Ngenxa yesithiyo se-steric seqembu le-o-methyl, umsebenzi wokusabela uphansi kunowe-TDI kanye ne-MDI.

Uma kuqhathaniswa nama-elastomer e-polyurethane asekelwe ku-NDI, ama-elastomer asekelwe ku-TODI, ama-polyol e-oligomer kanye ne-MOCA anezakhiwo ezifanayo zomzimba, njengokumelana nokushisa okuhle kakhulu, ukumelana ne-hydrolysis kanye nezakhiwo zemishini. Uma kuqhathaniswa namarabha, amapulasitiki nezinsimbi, ama-elastomer asekelwe ku-TODI anezinzuzo eziningi kakhulu, ahlala isikhathi eside, ukumelana nokushisa kanye nokumelana ne-hydrolysis. Ama-elastomer asekelwe ku-TODI anikeza izakhiwo zemishini ezingcono kakhulu ezingasetshenziswa lapho usebenza ngaphansi kwezimo ezinzima kanye/noma indawo. Ngaphezu kwalokho, ngenxa yokuphila kwayo isikhathi eside ebhodweni, i-prepolymer esekelwe ku-TODI kulula ukuyiphatha uma iqhathaniswa nemikhiqizo esekelwe ku-NDI.

Isicelo

Ngezakhiwo zayo ezinhle kakhulu zemishini namakhemikhali, ama-elastomer asekelwe ku-TODI asetshenziswa kabanzi emikhakheni eyahlukene. Okokuqala, izingxenye zokuvala, njengokuvala uwoyela, indandatho yepiston, izivalo zamanzi njalo njalo. Bese kuthi izingxenye zezimoto ziwuhlelo olukhulu lwe-TODI, okuhlanganisa izandiso ze-bumper, ama-shock absorber, ama-grill nokunye. Ngaphandle kwalokho, ukusetshenziswa kwezimboni okuphezulu, okungukuthi amabhande, ama-roll, ama-casters. Ngaphezu kwalokho, i-TODI iyi-ejenti ebalulekile yokumboza emkhakheni kagesi kanye nezitho zokwenziwa emishinini yezokwelapha.

Ukupakisha Nokugcina Izinto

Ukupakisha: 50kgs/isigubhu sensimbi.

Ukugcinwa Nokuthuthwa: I-TODI iyazwela umswakama. Amanzi asabela nawo wonke ama-diisocyanate ukuze akhe ama-urea derivatives angancibiliki. I-TODI kufanele igcinwe ezitsheni ezivalwe kahle ezimweni ezipholile nezomile.

UNGAYIFAKI i-TODI kanye nokudla futhi ugweme ukuyiveza endaweni eshisa ngaphezu kuka-30°C. Ngemva kokusebenzisa, isivalo kumele sivalwe ngokushesha uma kwenzeka ukungasebenzi kahle. Ngaphansi kwezimo zokugcina ezifanele, i-TODI isebenza izinyanga eziyisithupha okungenani kusukela ngosuku efike ngalo.
