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

Hoʻolauna

ʻO 1,3-Bis [3-(dimethylamino) propyl]urea, i ʻike ʻia ʻo DMTU, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:

- Ke ʻano: DMTU he kala ʻole a māmā melemele paʻa.

- Solubility: DMTU maikaʻi ka solubility i nā mea hoʻoheheʻe maʻamau e like me ka wai, nā waiʻona, a me nā etera.

- Paʻa: Paʻa ka DMTU ma lalo o nā kūlana kemika maʻamau.

E hoʻohana:

- Urami-agent: ʻO DMTU kahi mea hana ururalizing hiki ke hoʻohana ʻia e synthesize i ka urea gum, spandex fibers a me spandex elastane fibers, a me nā mea ʻē aʻe.

- Nā mea pale ahi: Hiki ke hoʻohana ʻia ka DMTU ma ke ʻano he halogen-free flame retardant i nā mea synthetic e like me ka polyamide resins, polyurethane resins, a me nā polyimides e hoʻomaikaʻi ai i kā lākou mau mea pale ahi.

Hanana:

- Hoʻopili nui ʻia ʻo DMTU me ka dimethylamine me 3-chloroacetone e hana i waena, a laila hana me ka urea e loaʻa ai ka huahana hope.

ʻIke palekana:

- ʻAʻole helu ʻia ʻo DMTU ma ke ʻano he carcinogen a mea ʻawaʻawa paha.

- I ka hoʻohana ʻana a i ʻole ka lawelawe ʻana i nā DMTU, pono e mālama ʻia e hahai i nā kaʻina hana palekana kūpono, e like me ka pale ʻana i ka inhalation a i ʻole ka hoʻopili ʻana me ka ʻili a me nā maka, a me ka hōʻoia ʻana i kahi wahi hana maikaʻi.

- I ka mālama ʻana a me ka lawe ʻana, pono e ʻalo ʻia ka hoʻopili ʻana me nā oxidants a me nā ʻakika ikaika e pale aku i nā hopena pōʻino.
