amakuru

Polyethylenimine (PEI)ni amazi ya elegitoronike.Ubwinshi bwamazi yibicuruzwa byubucuruzi mubisanzwe ni 20% kugeza 50%.PEI ni polymerized kuva muri Ethylene imide monomer.Ni polymer cationic isanzwe igaragara nkibara ritagira ibara ryumuhondo cyangwa rikomeye hamwe nuburemere butandukanye bwa molekile hamwe nuburyo butandukanye.

Nikipolyethyleneimineimikorere?

1. Kwizirika kwinshi, kwinjiza amine amatsinda menshi birashobora kwitwara hamwe nitsinda rya hydroxyl kugirango bibumbire hamwe hydrogène, itsinda rya amine rirashobora kwitwara hamwe nitsinda rya carboxyl gukora ionic bond, itsinda rya amine naryo rishobora kwitwara hamwe nitsinda rya karubone acyl kugirango rihuze ubumwe.Muri icyo gihe, bitewe nitsinda ryayo (amine) hamwe nitsinda rya hydrophobique (vinyl), irashobora guhuzwa nibintu bitandukanye.Hamwe nimbaraga zuzuye zihuza, irashobora gukoreshwa cyane mubice byo gufunga, wino, irangi, guhuza nibindi.

2. Imide-cationic polyvinyl imide ibaho muburyo bwa polycation mumazi, ishobora gutesha agaciro no adsorb ibintu byose bya anionic.Irigata kandi ibyuma biremereye.Hamwe nimiterere yacyo yo hejuru, irashobora gukoreshwa mugukora impapuro, gutunganya amazi, gukemura amasahani, gutatanya nindi mirima.

3. Polyethylenimine ikora cyane kubera amine yibanze na kabiri ya amine, kuburyo ishobora kubyitwaramo byoroshye na epoxy, acide, isocyanate hamwe na gaze ya aside.Ukoresheje uyu mutungo, urashobora gukoreshwa nka epoxy reaction, aldehyde adsorbent hamwe numukozi wo gutunganya amabara.

Polyethylenimine ikoreshwa iki?

Polyethylenimine (PEI)ni impinduramatwara itandukanye ya polymer hamwe nuburyo butandukanye bwo gukoresha, harimo ariko ntibugarukira kuri:

1. Gutunganya amazi ninganda.Nkumukozi ufite imbaraga zitose, ikoreshwa mumpapuro zidashiramo (nk'impapuro zungurura, impapuro zohanagura wino, impapuro zo mu musarani, nibindi), zishobora kuzamura imbaraga zitose zimpapuro no kugabanya ibyangiritse mugutunganya impapuro, mugihe byihuta gushungura amazi ya pulp no gukora fibre nziza byoroshye guhindagurika.

2. Umukozi wo gutunganya amabara.Ifite imbaraga zikomeye zo gusiga amarangi ya aside kandi irashobora gukoreshwa nkigikorwa cyo gutunganya mugihe aside irangi irangi irangi.

3. Guhindura fibre hamwe nabafasha.Kubuvuzi bwa fibre, nk'intwaro z'umubiri, gants zo kurwanya gukata, umugozi, nibindi.

4. Ibikoresho bya elegitoroniki.Mu rwego rwa elegitoroniki, firime ya polyethylene imide irashobora gukoreshwa nkigice cyitaruye, ikingira ibikoresho kandi igapfundikira ibice bya elegitoroniki, nibindi, hamwe nibikorwa byiza byo gukumira no kurwanya ubushyuhe bwinshi.

5. Gupakira ibiryo.Nkibikoresho byo gupakira ibiryo, bifite ibyiza byo kutagira ubushyuhe, kurwanya gaze neza, kutagira uburozi, uburyohe, kurwanya ubushyuhe bwinshi, nibindi, kandi bikoreshwa cyane mugupakira inyama, inkoko, imbuto, imboga, ikawa na ibindi bicuruzwa.

6. Ibikoresho byo kwa muganga.Polyvinylimine irashobora gukoreshwa mubikoresho byubuvuzi, ibikoresho byo gusuzuma, gupakira kwa muganga, nibindi, nkimyambarire yubuvuzi na firime zibonerana.

7. Ibifatika.Nkibikoresho bifatika cyane, bikoreshwa mugukora ikirere, ibikoresho bya elegitoronike, ibice byimodoka nibindi.

8. Ibikoresho byo gutunganya amazi no gutatanya.Ikoreshwa cyane mugutunganya amazi, gutunganya amashanyarazi, gutatanya nindi mirima.Umwikorezi.Polyvinylimide ni virusi idafite virusi yo gutanga gene, cyane cyane ikwiranye no kwanduza plasmide nyinshi.

Byongeye,polyethylenimineifite kandi ibiranga kwifata cyane, adsorption nyinshi, cation nyinshi, reaction nyinshi, nibindi, kandi ikoreshwa cyane mubice byo gusiga irangi, wino, ibifata, kuvura fibre, gutunganya imyanda nibindi.

Muri rusange, polyvinylimide ni polymer itandukanye hamwe nurwego runini rwa porogaramu, kandi imitungo yayo irashobora guhinduka no gutezimbere muguhindura uburemere bwa molekile, imiterere n'imikorere.
