Isingeniso

I-Diphenylmethane-4,4'-disocyanate, eyaziwa nangokuthi i-MDI. Kuyinhlanganisela yezinto eziphilayo futhi kuwuhlobo lwezinhlanganisela ze-benzodisocyanate.

Ikhwalithi:

1. Ukubukeka: I-MDI ayinambala noma iqinile ephuzi ngokukhanyayo.

2. Ukunyibilika: I-MDI iyancibilika kuzincibilikisi zemvelo njengama-hydrocarbon ane-chlorine nama-hydrocarbon anephunga elimnandi.

Sebenzisa:

Isetshenziswa njengempahla eluhlaza ye-polyurethane compounds. Ingasabela nge-polyether noma i-polyurethane polyols ukuze yakhe ama-polyurethane elastomers noma ama-polymers. Le nto inezinhlobonhlobo zezicelo zokwakha, izimoto, ifenisha, nezicathulo, phakathi kokunye.

Indlela:

Indlela ye-diphenylmethane-4,4'-disocyanate ngokuyinhloko iwukusabela i-aniline ne-isocyanate ukuze ithole isocyanate esekelwe ku-aniline, bese idlula ekuphenduleni kwe-diazotization kanye ne-denitrification ukuze kutholwe umkhiqizo oqondiwe.

Ulwazi Lokuphepha:

1. Gwema ukuthintana: Gwema ukuthintana ngqo nesikhumba futhi uhlonyiswe ngezinto zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela.

2. Ukungenisa umoya: Gcina izimo ezinhle zokungenisa umoya ngesikhathi sokusebenza.

3. Isitoreji: Lapho uyigcina, kufanele ivalwe futhi igcinwe kude nemithombo yomlilo, imithombo yokushisa kanye nezindawo lapho imithombo yokuvutha ivela khona.

4. Ukulahlwa kwemfucuza: Imfucuza kufanele iphathwe kahle futhi ilahlwe, futhi akufanele ilahlwe ngokuthanda kwakho.

Lapho uphatha izinto zamakhemikhali, kufanele ziphathwe ngokuhambisana ngokuqinile nezinqubo zokusebenza zaselabhorethri neziqondiso zokuphepha, futhi ngokuhambisana nemithetho neziqondiso ezifanele.

Okwedlule: I-Methylenediphenyl disocyanate(CAS#26447-40-5)

Olandelayo: I-Diiodomethane(CAS#75-11-6)
