Intangiriro

Diphenylmethane-4,4′-diisocyanate, izwi kandi nka MDI. Nibintu kama kandi ni ubwoko bwimvange ya benzodiisocyanate.

Ubwiza:

1. Kugaragara: MDI nta ibara cyangwa ibara ry'umuhondo ryoroshye.

2. Gukemura: MDI irashonga mumashanyarazi nka hydrocarbone ya chlorine na hydrocarbone ya aromatic.

Koresha:

Ikoreshwa nkibikoresho fatizo bya polyurethane. Irashobora kwitwara hamwe na polyurethane polyole kugirango ikore polyurethane elastomers cyangwa polymers. Ibi bikoresho bifite uburyo bwinshi bwo gukoresha mubwubatsi, ibinyabiziga, ibikoresho byo mu nzu, n'inkweto, n'ibindi.

Uburyo:

Uburyo bwa diphenylmethane-4,4′-diisocyanate nugukora cyane cyane gukora aniline hamwe na isocyanate kugirango ubone isocyanate ishingiye kuri aniline, hanyuma unyuze muri diazotisation reaction na denitrification kugirango ubone ibicuruzwa bigenewe.

Amakuru yumutekano:

2. Guhumeka: Komeza uburyo bwiza bwo guhumeka mugihe ukora.

3. Ububiko: Iyo bubitse, bugomba gufungwa kandi bugashyirwa kure yumuriro, inkomoko yubushyuhe n’aho inkomoko yabyo.

4. Kujugunya imyanda: Imyanda igomba gutunganywa neza no kujugunywa, kandi ntigomba kujugunywa uko bishakiye.

Iyo ikora ibintu bya shimi, bigomba gukemurwa hubahirijwe uburyo bukoreshwa muri laboratoire n’amabwiriza y’umutekano, kandi hakurikijwe amategeko n'amabwiriza abigenga.

Mbere: Methylenediphenyl diisocyanate (CAS # 26447-40-5)

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