1 3-bis[3-(dimethylamino)propyl]urea(CAS# 52338-87-1)

Mawu Oyamba

1,3-Bis[3-(dimethylamino)propyl]urea, yomwe imadziwikanso kuti DMTU, ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:

Ubwino:

- Maonekedwe: DMTU ndi yolimba yopanda mtundu kapena yopepuka.

- Kusungunuka: DMTU ili ndi kusungunuka kwabwino mu zosungunulira wamba monga madzi, ma alcohols, ndi ma ether.

- Kukhazikika: DMTU ndiyokhazikika pamikhalidwe wamba.

Gwiritsani ntchito:

- Urami-agent: DMTU ndi ururalizing agent yomwe ingagwiritsidwe ntchito kupanga urea chingamu, spandex ulusi ndi spandex elastane ulusi, pakati pa ena.

- Ma retardants amoto: DMTU itha kugwiritsidwa ntchito ngati choletsa moto wopanda halogen muzinthu zopangidwa monga ma resins a polyamide, ma resins a polyurethane, ndi ma polyimides kuti apititse patsogolo mphamvu zawo zoletsa malawi.

Njira:

- DMTU imakhudzidwa makamaka ndi dimethylamine yokhala ndi 3-chloroacetone kupanga yapakatikati, kenako imakumana ndi urea kuti ipeze mankhwala omaliza.

Zambiri Zachitetezo:

- DMTU pakadali pano sikudziwika ngati carcinogen kapena mankhwala oopsa.

- Mukamagwiritsa ntchito kapena kugwira ma DMTU, kuyenera kutsatiridwa kutsatira njira zoyenera zotetezera, monga kupewa kutulutsa mpweya kapena kukhudzana ndi khungu ndi maso, komanso kuonetsetsa kuti malo ogwirira ntchito ali ndi mpweya wabwino.

- Posunga ndi kunyamula, kukhudzana ndi okosijeni ndi zidulo zamphamvu kuyenera kupewedwa kuti mupewe zoopsa.
