amakuru

Polyethylenemine (PEI)ni polymeri ishobora gushonga mu mazi. Ubusanzwe ingano y'amazi mu bicuruzwa by'ubucuruzi iba iri hagati ya 20% na 50%. PEI ikorwa muri polymeri iva muri ethylene imide monomer. Ni polymeri ya cationic ikunze kugaragara nk'amazi adafite ibara cyangwa umuhondo cyangwa akomeye afite uburemere butandukanye bwa molekile n'imiterere itandukanye.

Ni ikipolyethyleneimineimikorere?

1. Itsinda rya amino rifatana cyane, rishobora gukorana n’itsinda rya hydroxyl rigakora umugozi wa hydrogen, itsinda rya amine rishobora gukorana n’itsinda rya karubokisili rigakora umugozi wa ionic, itsinda rya amine rishobora kandi gukorana n’itsinda rya acyl ya karuboni kugira ngo rikore umugozi wa covalent. Muri icyo gihe, bitewe n’imiterere yaryo ya polar (amine) n’itsinda rya hydrophobic (vinyl), rishobora guhuzwa n’ibintu bitandukanye. Hamwe n’izi mbaraga zihuriweho, rishobora gukoreshwa cyane mu bijyanye no gufunga, wino, irangi, gufunga n’ibindi.

2. Polyvinyl imide ifite cationic nyinshi iba mu buryo bwa polycation mu mazi, ishobora gukurura no gukurura ibintu byose bya anionic. Inakuraho iyoni z'icyuma gikomeye. Kubera imiterere yayo ya cationic nyinshi, ishobora gukoreshwa mu gukora impapuro, gutunganya amazi, gupakira, gukwirakwiza amazi n'ibindi.

3. Polyethylenemine ikora cyane bitewe n'amine za mbere n'iza kabiri zikora cyane, bityo ishobora gukora byoroshye hamwe na epoxy, aside, imvange ya isocyanate na gaze za aside. Ikoresheje iyi miterere, ishobora gukoreshwa nk'imvange ya epoxy, aldehyde adsorbent n'umuti ufata amabara.

Polyethylenemine ikoreshwa iki?

Polyethylenemine (PEI)ni imvange ya polymeri ikoreshwa mu buryo butandukanye, harimo ariko idagarukira kuri:

1. Inganda zitunganya amazi n'impapuro. Nk'igikoresho cyongera imbaraga z'amazi, gikoreshwa mu mpapuro zitose (nk'impapuro ziyungurura, impapuro zipfuka wino, impapuro z'ubwiherero, nibindi), bishobora kongera imbaraga z'impapuro zitose no kugabanya kwangirika kw'impapuro, mu gihe byihutisha kuyungurura amazi mu mpapuro no gutuma insinga nto zoroshye zigwa.

2. Uburyo bwo gufatanya amabara. Bufite imbaraga zikomeye zo gufatanya amabara ya aside kandi bushobora gukoreshwa nk'uburyo bwo gufatanya amabara iyo aside ikoresheje impapuro zishushanya irangi.

3. Guhindura no gusiga irangi ry'imigozi. Ku bijyanye no kuvura imigozi, nk'ingufu zo kwirinda gukata, uturindantoki two kwirinda gukata, umugozi, n'ibindi.

4. Ibikoresho by'ikoranabuhanga. Mu rwego rw'ikoranabuhanga, firime ya polyethylene imide ishobora gukoreshwa nk'urwego rwo kwitandukanya, ibikoresho bikingira ubushyuhe no gutwikira ibice by'ikoranabuhanga, nibindi, ifite ubushobozi bwiza bwo gukingira ubushyuhe no kwihanganira ubushyuhe bwinshi.

5. Gupfunyika ibiryo. Nk'ibikoresho byo gupfunyika ibiryo, bifite ibyiza byo kwirinda ubushuhe, kurwanya umwuka mwiza, kudahumanya, kudakoresha uburyohe, kudakoresha ubushyuhe bwinshi, nibindi, kandi bikoreshwa cyane mu gupfunyika inyama, inkoko, imbuto, imboga, ikawa n'ibindi bicuruzwa.

6. Ibikoresho by'ubuvuzi. Polyvinylimine ishobora gukoreshwa mu bikoresho by'ubuvuzi, ibikoresho byo gusuzuma indwara, mu gupfunyika kwa muganga, nibindi, nk'imyambaro yo kwa muganga n'amafilimi abonerana y'ubuvuzi.

7. Kole. Nk'ikole ifite imikorere myiza, ikoreshwa mu gukora indege, ibikoresho by'ikoranabuhanga, ibice by'imodoka n'ibindi.

8. Ibikoresho byo gutunganya amazi n'ibiyangiza. Bikoreshwa cyane mu gukora impapuro zo gutunganya amazi, gukoresha amashanyarazi, kuyasya n'ahandi. Ifite imiterere y'uturemangingo. Polyvinylimide ni vector idatera virusi mu gutanga imiterere y'uturemangingo, cyane cyane ikwiriye mu guteranya plasmidi nyinshi.

Byongeye kandi,polyethylenemineIfite kandi imiterere yo gufatana cyane, gukurura cyane, gukurura cyane, gukorana neza cyane, nibindi, kandi ikoreshwa cyane mu bijyanye n'irangi, wino, kole, gutunganya fibre, gutunganya imyanda n'ibindi.

Muri rusange, polyvinylimide ni polymer ifite uburyo bwinshi bwo kuyikoresha, kandi imiterere yayo ishobora guhindurwa no kunozwa binyuze mu guhindura uburemere bwa molekile, imiterere n'imikorere yayo.
