Ubunzima beemolekyuli ezininzi POLYETHYLENEImine/PEI cas 9002-98-6

Inkcazelo emfutshane:

I-Polyethyleneimine (PEI) yipolymer enamasebe amaninzi eyenziwe nge-ethyleneimine monomers.Ngolwakhiwo lwayo lomxokelelwane omde, i-PEI ibonisa iipropathi ezincamathelayo ezibalaseleyo, iyenza ibe lolona khetho lufanelekileyo kwizicelo ezahlukeneyo, kubandakanywa neengubo zamaphepha, amalaphu, izinto zokuncamathelisa, kunye nokuguqulwa komphezulu.Ngaphaya koko, ubume be-cationic be-PEI buyivumela ukuba ibophelele ngokusebenzayo kwiisubstrates ezihlawuliswa kakubi, iphucula ukuguquguquka kwayo kumashishini ahlukeneyo.

Ukongeza kwiipropathi zayo zokuncamathelisa, i-PEI ikwabonisa amandla akhethekileyo okuthintela, aluncedo kwiindawo ezininzi ezifana nokucocwa kwamanzi amdaka, ukubanjwa kwe-CO2, kunye ne-catalysis.Ubunzima bayo obuphezulu be-molecular buvumela i-adsorption esebenzayo kwaye ekhethiweyo, eyenza ibe yinto exabisekileyo ekuhlanjululweni kweegesi kunye nolwelo.

Iingenelo

1. I-Adhesives: Iimpawu eziqinileyo ze-PEI zenza ukuba ibe yinto ebalaseleyo ekuqulunqweni kwe-adhesives kumashishini ahlukeneyo, kuquka i-woodworking, ukupakishwa, kunye ne-automotive.

2. Iimpahla ezilukiweyo: Ubume be-PEI be-cationic buyenza ukuba ikhulise ukugcinwa kwedayi kunye nokuphucula ukuzinza kwe-dimension ye-textile ngexesha lokulungiswa.

3. Iingubo zePhepha: I-PEI ingasetyenziselwa njenge-binder kwiingubo zephepha, ukwandisa amandla ephepha kunye nokuphucula ukuprintwa kunye nokuchasana kwamanzi.

4. Ukuguqulwa koMphezulu: I-PEI iphucula umgangatho wezinto eziphathekayo, kubandakanywa isinyithi kunye neepolymers, okuvumela ukunamathela okungcono kunye nokuphucula ukuqina.

5. I-CO2 Capture: Ikhono le-PEI lokubamba ngokukhethiweyo i-CO2 yenze ukuba ibe sisixhobo esibalulekileyo kwi-teknoloji yokubamba i-carbon, inceda ekunciphiseni ukukhutshwa kwe-greenhouse gas.

Ukuqukumbela, i-polyethyleneimine (i-CAS: i-9002-98-6) yinto exutywe kakhulu yeekhemikhali ezixutywe kakhulu kunye neempawu ezinamathele kunye ne-buffering.Uluhlu lwayo olubanzi lwezicelo luyenza ibe yinto ebalulekileyo kumashishini ahlukeneyo, ukuqinisekisa ukuphuculwa kokusebenza kwemveliso kunye nokusebenza kakuhle.
