amakuru

Polyethyleneimine (PEI) Cas 9002-98-6ifite uburyo bwinshi bwo gukoreshwa mu nganda z'imyenda kandi ni ibikoresho by'ingenzi bya polymer. Agaciro kayo k'ingenzi kari mu miterere yayo myinshi ya positive charge hamwe n'uburyo ikora neza cyane, bigatuma ihuzwa n'imigozi, amarangi, n'ibindi bikoresho bitandukanye bikora neza, bityo iha imyenda imiterere mishya cyangwa inoze.

Ibi bikurikira ni byo bikorwa by'ingenzi n'agaciro kabyoPEImu nganda z'imyenda:

Ⅰ. Gusiga irangi no gucapa: Kongera imikorere y'amabara no kubungabunga ibidukikije

PEIbinoza cyane ingaruka zo gusiga irangi no gucapa imyenda binyuze mu gufatanya ibice byayo bya cationic na anionic, ariko bigabanya umwanda.

1. Ubujyakuzimu bw'Irangi (Agaciro ka K/S) n'Uburemere bw'Ibara:

Imyenda yasizwe ikoresheje PEI nk'ipamba n'ubwoya igaragaza uburyo irangi rirushaho kwiyongera, bigatuma amabara yimbitse kandi agaragara neza. Muri icyo gihe, imiterere itandukanye y'amabara y'imyenda yasizwe irangi n'iyacapwe (nk'uburyo bwo gukaraba no kudasiga irangi) irushaho kuba myiza cyane. Urugero, ubushakashatsi bwakozwe mu 2025 bwagaragaje ko ijanisha ry'ubukana bw'amabara (agaciro ka K/S) ry'imyenda yasizwe ikoresheje PEI ryiyongereye cyane.

2. Kugera ku icapiro rya Inkjet ritakoreshejwe/ridafite amazi mbere yo kuvurwa:

Gukoresha hyperbranchedpolyethyleneimine (PEI)Inki z’irangi zahinduwe (nk’iyingi ya PEI-R218), gucapa inki bishobora gukorwa ku myenda itavuwe neza, bigatuma irangi rifata ingano irenga 98.7%. Ibi bikuraho uburyo bwo gukaraba mbere yo gucapa no kumesa nyuma yo gucapa, bigabanya cyane ikoreshwa ry’imiti, amazi n’ingufu.

3. Guteza imbere ikoreshwa ry'irangi karemano:

Imyenda ya silike yahinduwe na PEI ishobora kunoza neza igipimo cyo gusiga irangi n'ingaruka zo gusiga irangi ry'amabara karemano nka curcumin, bigateza imbere uburyo bwo gusiga irangi butangiza ibidukikije.

II. Gusoza imikorere: Guha imyenda "imbaraga zidasanzwe"

PEIni ikintu cy'ingenzi mu gukora imyenda ikora, cyane cyane ikaba nziza mu kugabanya umuriro.

1. Kudakoresha umuriro neza cyane

Ikungahaye kuri azote,PEIikunze gukoreshwa nk'isoko ya karuboni cyangwa gaze mu buryo butuma umuriro utagira umuriro ugera ku gipimo cyawo, ikorana n'ibindi bintu bitera umuriro birimo fosifore na silikoni.

Imyenda ya kotoni: Iyo ihujwe n'ibintu bigabanya umuriro bishingiye ku binyabuzima nka aside phytic (PA), no binyuze mu guhinduranya iyoni cyangwa gushyiramo ibikoresho bihuza, hashobora gukorwa irangi rigabanya umuriro neza cyane.

2. Imyenda ya viscose

PEI ifite fosfeti, nk'ikintu kidakoresha umuriro, ishobora kongera igipimo cya ogisijeni (LOI) ku mwenda kugeza kuri 28.9%, bigatuma ihita izimya umuriro iyo ikuweho.

3. PA56, PAN, n'izindi fibre zikoze mu buhanga

Binyuze mu ikoranabuhanga ryo gushyiramo ibikoresho cyangwa ikoranabuhanga ryo kwihuza, imiyoboro ihuza ishobora gukorwa, bigatuma umuriro udakira neza. Urugero, umwenda wa PAN wavuwe na PA/PEI/APTES ugaragaza ko igipimo cya ogisijeni (LOI) kiri hejuru kuva kuri 17.4% kugeza kuri 27.5%, kandi ugaragaza ubushobozi bwiza bwo gukumira umwotsi.

4. Imiterere y'imiti irwanya bagiteri n'irwanya ogisijeni

PEI ubwayo hamwe n'ibinyabutabire byayo byo guhuza ibyuma (nka PEI-Cu) bifite ubushobozi bwo kurwanya bagiteri. Imyenda y'ipamba yavuwe na PEI yagaragaje ubushobozi bwo kurwanya bagiteri ku kigero cya 83.33% na 74.2% mu gukoresha nanogenerateur ya triboelectric (T-TENG).

5. Imiterere yoroshye yo gutwara ibintu n'ibintu birwanya imihindagurikire y'ikirere:

Uburinzi bwa elegitoroniki: Uburinzi bwa polyamide (PA) bwahinduwe na PEI bukomeza cyane gufatana kwa graphene oxide (GO). Uburinzi butuma bugumana uburinzi bwa 4.7 × 10³ S/m nyuma y’ingufu 10.000, bugera ku burinzi bwa elegitoroniki bugera kuri 66.7 dB.

6. Imiterere irwanya imihindagurikire y'ikirere

PEIbyongera ubushobozi bwo gutwikira imyenda, bigabanya ubwiyongere bw'amashanyarazi adahindagurika.

7. Ubwoya burwanya uburibwe

Uburyo buhoraho bwo kurangiza isuku hakoreshejwe potasiyumu persulfate (PMS)-PEI mu ntambwe ebyiri ni uburyo butagira chlorine kandi butangiza ibidukikije.

8. Kongera ubushobozi bwo gutoha no gukurura amazi

PEIUburyo bwo kuvura butuma insinga zitose nk'ubwoya zitose cyane, aho PEI ifite uburemere bwinshi igaragaza umusaruro mwiza.

III. Guhindura ubuso: Kubaka "ikiraro" gikora

PEIishobora gukoreshwa nk' "urwego rwo guhuza" cyangwa "igikoresho cyo gufunga" mu guhindura fibre yimbitse.

1. Kongera imbaraga zo gusiga

Nk'igitambaro cyo hasi, PEI ishobora kunoza cyane imbaraga zo gupakira no gufatanya ibikoresho (nka MXene (Ti₃C₂Tₓ) na graphene oxide (GO)) ku buso bwa fibre.

2. Gutegura ibinyabutabire bikora

Ishobora gukoreshwa mu gutegura ibintu bivanze nka PEI@PLA aerogels kugira ngo ikoreshwe nko gukoresha irangi.

3. Gushyiramo imiti igabanya ubukana bw'ibinyabutabire mu buryo bwa "Catalytic Chemical Plating"

Nk'ikintu gifasha mu gukamura ipamba, gishobora gukoreshwa mu gutunganya insinga z'ipamba, bigatuma umuringa sulfide (CuS) ushyirwa ku buso bwabyo, bityo bigatuma habaho imikorere y'amashanyarazi.

Ⅳ.Incamake

Polyethyleneimine (PEI)Ifite agaciro mu nganda z'imyenda mu byiciro byose, kuva ku gusiga amarangi no kurangiza neza kugeza ku gutegura imvange zikora neza. Ntabwo ari "inyongera" gusa mu kunoza imikorere no kubungabunga ibidukikije by'imyenda gakondo (ipamba, ubwoya, silk), ahubwo ni n'ibikoresho by'ingenzi mu guteza imbere imyenda igezweho ifite ubwenge, irinda kandi ikora neza.

Icyitonderwa ni uko ingaruka zo gukoreshaPEIifitanye isano rya hafi n'imiterere yayo nk'uburemere bwa molekile n'urwego rw'amashami. Mu mikoreshereze ifatika, ni ngombwa kuyihitamo no kuyinoza hakurikijwe inzira yihariye.
