Mawu Oyamba

Diphenylmethane-4,4'-disocyanate, yomwe imadziwikanso kuti MDI. Ndi organic pawiri ndipo ndi mtundu wa benzodisocyanate mankhwala.

Ubwino:

1. Maonekedwe: MDI ndi yopanda mtundu kapena yolimba yachikasu.

2. Kusungunuka: MDI imasungunuka mu zosungunulira za organic monga ma chlorinated hydrocarbons ndi mafuta onunkhira a hydrocarbon.

Gwiritsani ntchito:

Amagwiritsidwa ntchito ngati zopangira zopangira polyurethane. Itha kuchitapo kanthu ndi polyether kapena polyurethane polyols kupanga polyurethane elastomers kapena ma polima. Nkhaniyi ili ndi ntchito zambiri zomanga, magalimoto, mipando, nsapato, ndi zina.

Njira:

Njira ya diphenylmethane-4,4'-disocyanate makamaka kuchitapo kanthu aniline ndi isocyanate kupeza aniline-based isocyanate, ndiyeno kudutsa diazotization reaction ndi denitrification kupeza chandamale mankhwala.

Zambiri Zachitetezo:

1. Pewani kukhudzana: Pewani kukhudza khungu ndipo khalani ndi zida zoyenera zodzitetezera monga magolovesi, magalasi ndi zovala zodzitetezera.

2. Mpweya wabwino: Sungani bwino mpweya wabwino panthawi yogwira ntchito.

3. Kasungidwe: Posunga, iyenera kutsekedwa ndi kusungidwa kutali ndi kumene kuyatsa moto, komwe kumatenthetsa ndi kumene kuyatsa kumachitika.

4. Kutaya zinyalala: Zinyalala ziyenera kusamaliridwa bwino ndi kutayidwa, ndipo siziyenera kutayidwa mwakufuna kwake.

Pogwira zinthu za mankhwala, ziyenera kusamaliridwa motsatira njira zogwirira ntchito za labotale ndi malangizo achitetezo, komanso motsatira malamulo ndi malamulo oyenera.

Zam'mbuyo: Methylenediphenyl diisocyanate(CAS#26447-40-5)

Ena: Diiodomethane(CAS#75-11-6)
