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

Isingeniso

I-1,3-Bis[3-(dimethylamino)propyl]urea, eyaziwa nangokuthi i-DMTU, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:

- Ukubukeka: I-DMTU iqinile engenambala noma ephuzi ngokukhanyayo.

- Ukunyibilika: I-DMTU inokuncibilika okuhle kuzincibilikisi ezivamile ezifana namanzi, utshwala, nama-ether.

- Ukuzinza: I-DMTU izinzile ngaphansi kwezimo zamakhemikhali ezivamile.

Sebenzisa:

- I-Urami-ejenti: I-DMTU iyi-ejenti ebulalayo engasetshenziswa ukuze kuhlanganiswe i-urea gum, imicu ye-spandex kanye nemicu ye-spandex elastane, phakathi kokunye.

- Izinqamuleli zamalangabi: I-DMTU ingasetshenziswa njengesinqamuleli samalangabi esingena-halogen ezintweni zokwenziwa ezifana nezinsalela ze-polyamide, ama-polyurethane resins, nama-polyimides ukuze kuthuthukiswe izici zazo zokubuthisa ilangabi.

Indlela:

- I-DMTU ihlangana kakhulu ne-dimethylamine ne-3-chloroacetone ukuze yakhe indawo emaphakathi, bese ihlangana ne-urea ukuze ithole umkhiqizo wokugcina.

Ulwazi Lokuphepha:

- I-DMTU okwamanje ayihlukaniswa njenge-carcinogen noma into enobuthi.

- Uma usebenzisa noma uphatha ama-DMTU, kufanele kuqikelelwe ukulandela izinqubo ezifanele zokusebenza zokuphepha, njengokuvimbela ukuhogela umoya noma ukuthintana nesikhumba namehlo, nokuqinisekisa indawo yokusebenza enomoya omuhle.

- Lapho ugcina futhi uhambisa, ukuthintana nama-oxidants nama-asidi aqinile kufanele kugwenywe ukugwema ukusabela okuyingozi.
