Polyethylenimine(PEI)he polymer hiki ke hooheheeia i ka wai.ʻO ka manaʻo o ka wai o nā huahana kūʻai maʻamau he 20% a 50%.Ua polymerized ka PEI mai ka monomer ethylene imide.He polymer cationic ia e ʻike pinepine ʻia ma ke ʻano he wai kala ʻole i ka melemele a paʻa paha me nā ʻano kaumaha molekala a me nā ʻano like ʻole.

He ahapolyethyleneiminehana?

1. High adhesion, kiʻekiʻe absorption amino pūʻulu hiki ke hana me ka hydroxyl pūʻulu e hana hydrogen paʻa, amine hui hiki ke hana me ka carboxyl pūʻulu e hana ionic paʻa, amine pūʻulu hiki pū me ka carbon acyl hui e hana covalent paʻa.I ka manawa like, ma muli o kāna hui polar (amine) a me ka hui hydrophobic (vinyl), hiki ke hoʻohui ʻia me nā mea like ʻole.Me kēia mau pūʻali hoʻopaʻa paʻa, hiki ke hoʻohana nui ʻia i nā kahua o ka sila, ka inika, ka pena, ka mea hoʻopili a pēlā aku.

2. Loa'a ka imide polyvinyl ki'eki'e ma ke 'ano o ka polycation i loko o ka wai, hiki ke ho'oemi a adsorb i nā mea anionic a pau.Hoʻopili pū ia i nā ion metala kaumaha.Me kona mau waiwai cationic kiʻekiʻe, hiki ke hoʻohana ʻia i ka hana pepa, mālama wai, plating solution, dispersant a me nā māla ʻē aʻe.

3. ʻO ka polyethylenimine kiʻekiʻe loa ma muli o nā amine kumu mua a me ka lua, no laila hiki ke maʻalahi me ka epoxy, nā waikawa, nā pūhui isocyanate a me nā kinoea waikawa.Ke hoʻohana nei i kēia waiwai, hiki ke hoʻohana ʻia ma ke ʻano he epoxy reactant, aldehyde adsorbent a me kahi mea hoʻoponopono kala.

He aha ka polyethylenimine e hoʻohana ai?

Polyethylenimine (PEI)he hui polymer maʻamau me nā ʻano hoʻohana like ʻole, me ka ʻaʻole i kaupalena ʻia i:

1. ʻOihana wai a me ka ʻoihana pepa.Ma ke ʻano he mea ikaika pulu, hoʻohana ʻia ia i ka pepa absorbent ungummed (e like me ka pepa kānana, pepa blotting ink, pepa toilet, a me nā mea ʻē aʻe), hiki ke hoʻomaikaʻi i ka ikaika pulu o ka pepa a hōʻemi i ka pōʻino o ka hana pepa, ʻoiai e wikiwiki ana i ka hana. ka kānana wai o ka pulp a me ka hoʻomaʻamaʻa maʻalahi i nā fibers maikaʻi e flocculate.

2. Mea hoʻoponopono kala.He ikaika hoʻopaʻa paʻa ia no nā waiʻakaʻaka a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoponopono i ka wā e hoʻolele ai i ka pepa wai waika.

3. ʻO ka hoʻololi ʻana i ka fiber a me ka hoʻoluʻu ʻana i nā mea kōkua.No ka mālama ʻana i ka fiber, e like me ka pale kino, nā mīkina lima anti-cutting, ke kaula, etc.

4. Mea uila.Ma ke kahua o ka uila, hiki ke hoʻohana ʻia ke kiʻi ʻoniʻoni polyethylene imide ma ke ʻano he papa hoʻokaʻawale, mea hoʻokalakupua a me ka uhi ʻana o nā ʻāpana uila, etc., me ka hana insulation maikaʻi a me ke kūpaʻa wela kiʻekiʻe.

5. Hoʻopili meaʻai.Ma ke ʻano he mea ʻai meaʻai, loaʻa iā ia nā pono o ka moisture-proof, maikaʻi ke kinoea kūʻē, non-toxic, tasteless, high temperature resistance, etc. nā huahana ʻē aʻe.

6. Nā mea lapaʻau.Hiki ke hoʻohana ʻia ka Polyvinylimine i nā lāʻau lapaʻau, nā mea hana diagnostic, nā hōʻailona olakino, a me nā mea ʻē aʻe, e like me nā lole lapaʻau a me nā kiʻi ʻoniʻoni ʻoniʻoni.

7. Pili.Ma keʻano he mea hoʻopili kiʻekiʻe, hoʻohanaʻia ia i ka hanaʻana i ka aerospace, nā mea uila, nā'āpana kaʻa a me nā mea'ē aʻe.

8. Nā lāʻau lapaʻau wai a me nā dispersants.Hoʻohana nui ʻia ia i ka mālama ʻana i ka wai pepa, ka hopena electroplating, dispersant a me nā māla ʻē aʻe.Ka mea lawe gene.ʻO ka Polyvinylimide kahi vector non-viral no ka lawe ʻana i nā gene, kūpono loa no ka hoʻololi like ʻana o nā plasmids lehulehu.

Kahi mea hou aʻe,polyethylenimineloaʻa nō hoʻi nā hiʻohiʻona o ke kiʻekiʻe adhesion, kiʻekiʻe adsorption, kiʻekiʻe cation, kiʻekiʻe reactivity, etc., a ua hoʻohana nui ʻia i nā pā o ka pena, inika, adhesive, fiber treatment, sege treatment a pēlā aku.

Ma keʻano laulā, he polymer versatile ka polyvinylimide me ka nui o nā noi, a hiki ke hoʻoponopono a hoʻoponopono ʻia kona mau waiwai ma o ka hoʻololi ʻana i ke kaumaha molekala, ka hoʻolālā a me ka hana.
