Mawu Oyamba
Xylene diisocyanate.
Katundu: TDI ndi madzi achikasu owala opanda mtundu komanso onunkhira kwambiri. Ikhoza kusungunuka mu zosungunulira za organic ndipo imakhudzidwa ndi zinthu zambiri.
Ntchito: TDI amagwiritsidwa ntchito makamaka ngati zopangira za polyurethane, zomwe zingagwiritsidwe ntchito popanga thovu la polyurethane, polyurethane elastomer ndi zokutira, zomatira, etc. TDI imagwiritsidwanso ntchito m'malo monga mipando yamagalimoto, mipando, nsapato, nsalu ndi zokutira zamagalimoto. .
Njira yokonzekera: TDI nthawi zambiri imakonzedwa ndi zomwe xylene ndi ammonium bicarbonate pa kutentha kwakukulu. Zochitika zenizeni ndi kusankha kothandizira kungakhudze chiyero ndi zokolola za mankhwala.
Information Information Safety: TDI ndi chinthu choopsa chomwe chimakwiyitsa ndikuwononga khungu, maso ndi kupuma. Kuwona kwa nthawi yayitali kapena kukhala pachiwopsezo chachikulu kungayambitse kuwonongeka kwa kupuma, kusamvana, komanso kutupa pakhungu. Mukamagwiritsa ntchito TDI, muyenera kusamala bwino, monga kuvala zovala zoteteza maso, magolovesi ndi zopumira. Posunga ndi kusamalira TDI, pewani kukhudzana ndi zozimitsa moto ndikugwirira ntchito pamalo olowera mpweya wabwino. Popanga mafakitale pogwiritsa ntchito TDI, njira zoyendetsera chitetezo ndi malamulo oyenera ziyenera kutsatiridwa.
