MW800 MW 3500 Polyethylenimine CAS 25987-06-8 me ka awelika lālā Mw ~800 ma LS, awelika Mn ~600 e GPC
ʻO ka polyethylenimine kahi polyamine maʻamau i hiki ke hoʻoheheʻe ʻia i ka wai. Ma muli o ka waiwai naikokene nā mana ma ke kaulahao macromolecular, polyethylenimine i protophilicity ikaika, no laila, he laulā o nā noi, e like me flocculant i ka pepa a me ka pulping kahua, adsorption o metala iona i ka wai lapaʻau kahua, cationic polymer non viral gene. mea lawe ma ke kula lapaʻau, etc.

1. I ka ʻoihana pepa, hoʻohana ʻia ka polyethylenimine ma ke ʻano he mea kōkua, synergist a me ka kānana wai.
2. I ka ʻoihana fiber, hoʻohana ʻia ka polyethylenimine e like me ka mea ikaika pulu, anti-static treatment, flame retardant processing, shrink proof, dyeing improvement, etc.
3. Hoʻohana ʻia i nā uhi, inks, adhesives (me ka welding wela a me ka plastic packaging) hiki ke hoʻoikaika i ka hoʻopaʻa ʻana, ke kūpaʻa ʻana, hoʻomaikaʻi i ka puaʻa a me ka hoʻopiha piha ʻana, anti polymerization, hoʻomaikaʻi i ka paʻa o ka uhi, etc.
4. Hoʻohana ʻia i nā mea hoʻonaninani hiki ke hoʻomaikaʻi i ka maikaʻi o ka lauoho, antibacterial a me ka ʻili palupalu.
5. I ka hoʻohana ʻana i ka aila a me ka hana hohonu hohonu, hiki i ka polyethylenimine ke pale i ka nalowale o ka wai, hoʻemi i ka viscosity, pale i ka waiho ʻana o ka paraffin, a hoʻomaikaʻi i ka paʻa o ka pālolo.
6. Hiki ke hoʻohana 'ia ma ke kahua o ka lāʻau lapaʻau a me ka lāʻau lapaʻau e hoʻomaikaʻi i ka hoʻohālikelike ʻana ma waena o nā ʻāpana artificial a me ke koko. Hiki ke hoʻohana ʻia ka polyethylenimine ma ke ʻano he uhi no nā lāʻau lapaʻau.
7. Eia kekahi, o ka polyethylenimine kekahi mea o ka ion exchange resin a me ka exchange membrane, resin crosslinking agent, crystallization aid, electroplating gloss agent, metal rust inhibitor, gasoline and diesel combustion supporting agent, lubricating oil additive, glass clean agent, liquid chromatography. hoʻohana ʻia ka polyethylenimine ma ke aʻo ʻana i ke ʻano hoʻohālike enzyme synthetic.
Hoʻopili ʻia i loko o ka pahu 25kgs a mālama iā ia mai ka mālamalama ma kahi mahana ma lalo o 25 ℃.
