Nā kaumaha molekala lehulehu POLYETHYLENEIMINE/PEI cas 9002-98-6

ʻO ka wehewehe pōkole:

ʻO ka Polyethyleneimine (PEI) he polymer lālā nui i haku ʻia me nā monomers ethyleneimine.Me kona ʻano kaulahao lōʻihi, hōʻike ʻo PEI i nā waiwai adhesive maikaʻi loa, e lilo ia i koho kūpono no nā noi like ʻole, me ka uhi pepa, textiles, adhesives, a me ka hoʻololi ʻana i ka ʻili.Eia kekahi, ʻo ke ʻano cationic o PEI e hiki ai iā ia ke hoʻopaʻa pono i nā substrate i hoʻopiʻi ʻia, hoʻonui i kona versatility i nā ʻoihana like ʻole.

Ma waho aʻe o kāna mau waiwai adhesive, hōʻike pū ʻia ʻo PEI i nā mana buffering ʻokoʻa, he mea pono i nā wahi he nui e like me ka mālama ʻana i ka wai ʻino, hopu CO2, a me ka catalysis.ʻO kona kaumaha molecular kiʻekiʻe e hiki ai i ka adsorption maikaʻi a koho, e lilo ia i mea waiwai i ka hoʻomaʻemaʻe ʻana i nā kinoea a me nā wai.

- Huihui Molekala: (C2H5N)n

- Kaumaha Molecular: He ʻokoʻa, ma muli o ke ʻano o ka polymerization

- Ke ʻano: ʻO ka wai māmā, ʻeleʻele a paʻa paha

- Māmā: ʻAno like, maʻamau mai ka 1.0 a i ka 1.3 g/cm³

- pH: ʻAʻole kū ʻole i ka alkaline iki

- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe polar

Pono

1. Adhesives: ʻO nā mea hoʻopili ikaika o PEI e lilo ia i mea maikaʻi loa i ka hoʻokumu ʻana i nā adhesives no nā ʻoihana like ʻole, e like me ka hana lāʻau, hoʻopili, a me nā kaʻa.

2. Textiles: Hiki i ke ano cationic o PEI ke hoʻoikaika i ka paʻa ʻana o ke kala a hoʻomaikaʻi i ke ʻano paʻa o ka textiles i ka wā e hana ai.

3. Nā Pepa Pepa: Hiki ke hoʻohanaʻia ka PEI ma keʻano he mea hoʻopaʻa i nā pepa pepa, e hoʻonui i ka ikaika o ka pepa a me ka hoʻomaikaʻiʻana i kona hiki ke paʻi a me ka pale wai.

4. Hoʻololi i ka ʻili: Hoʻonui ka PEI i nā waiwai o ka ʻili o nā mea, me nā metala a me nā polymers, e ʻae ai i ka hoʻopili maikaʻi ʻana a me ka hoʻomaikaʻi ʻana i ka lōʻihi.

5. Hopu CO2: ʻO ka hiki i ka PEI ke kiʻi koho i ka CO2 ua lilo ia i mea hana waiwai i ka ʻenehana hopu kalapona, e kōkua ana i ka hōʻemi ʻana i ka hoʻokuʻu ʻia ʻana o ke kinoea.

I ka hopena, ʻo ka polyethyleneimine (CAS: 9002-98-6) he mea hoʻohui kemika nui loa me nā waiwai hoʻopili a hoʻopaʻa.ʻO kāna ākea o nā noi e lilo ia i mea koʻikoʻi i nā ʻoihana like ʻole, e hōʻoiaʻiʻo ana i ka hoʻomaikaʻi ʻana o ka huahana a me ka pono.
