Intshayelelo

I-Diphenylmethane-4,4'-disocyanate, eyaziwa ngokuba yi-MDI. I-organic compound kwaye luhlobo lwe-benzodisocyanate compounds.

Umgangatho:

1. Inkangeleko: I-MDI ayinambala okanye ukukhanya okuqinileyo okutyheli.

2. Ukunyibilika: I-MDI iyanyibilika kwizinyibilikisi zendalo ezifana neekhilobhoni eziklorini kunye neehydrocarbon ezinuka kamnandi.

Sebenzisa:

Isetyenziswa njengento ekrwada kwiikhompawundi polyurethane. Inokusabela nge-polyether okanye i-polyurethane polyols ukwenza i-polyurethane elastomers okanye iipolymers. Esi sixhobo sinoluhlu olubanzi lwezicelo kulwakhiwo, iimoto, ifenitshala, kunye nezihlangu, phakathi kwabanye.

Indlela:

Indlela ye-diphenylmethane-4,4'-diisocyanate ikakhulu ukusabela i-aniline kunye ne-isocyanate ukufumana i-aniline-based isocyanate, kwaye emva koko idlule kwi-diazotization reaction kunye ne-denitrification ukufumana imveliso ekujoliswe kuyo.

Ulwazi ngoKhuseleko:

1. Kulumkele ukudibana ngqo nolusu kwaye uxhotyiswe ngezixhobo ezifanelekileyo zokuzikhusela ezinjengeeglavu, iiglasi kunye nempahla yokuzikhusela.

2. Ukungenisa umoya: Gcina iimeko ezifanelekileyo zokungenisa umoya ngexesha lokusebenza.

3. Ugcino: Xa ugcina, kufuneka lutywinwe kwaye lugcinwe kude nemithombo yomlilo, imithombo yobushushu kunye neendawo apho imithombo yokutshisa iyenzeka khona.

4. Ukulahlwa kwenkunkuma: Inkunkuma kufuneka iphathwe kakuhle kwaye ilahlwe, kwaye akufanele ilahlwe ngokuthanda kwayo.

Xa uphatha izinto zeekhemikhali, kufuneka ziphathwe ngokungqongqo ngokuhambelana neenkqubo zebhubhoratri kunye nezikhokelo zokhuseleko, kwaye ngokuhambelana nemithetho kunye nemimiselo efanelekileyo.

Ngaphambili: I-Methylenediphenyl diisocyanate(CAS#26447-40-5)

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