Nhanganyaya

Diphenylmethane-4,4'-disocyanate, inozivikanwawo seMDI. Mushonga we organic uye imhando ye benzodisocyanate compounds.

 

Hunhu:

1. Kuonekwa: MDI haina ruvara kana chiedza yero yakasimba.

2. Solubility: MDI inonyungudika mune zvinonyungudutsa zveorganic zvakadai se chlorinated hydrocarbons uye anonhuwirira hydrocarbons.

 

Shandisa:

Inoshandiswa seyakagadzirwa zvinhu zve polyurethane makomisheni. Inogona kuita nepolyether kana polyurethane polyols kugadzira polyurethane elastomers kana mapolymers. Ichi chinyorwa chine huwandu hwakawanda hwekushandisa mukuvaka, mota, fenicha, uye shangu, pakati pezvimwe.

 

Nzira:

Iyo nzira ye diphenylmethane-4,4'-diisocyanate inonyanya kuita aniline ne isocyanate kuti iwane aniline-based isocyanate, uye wozoenda kuburikidza nediazotization reaction uye denitrification kuti uwane chigadzirwa chakananga.
