Polyethyleneimine (PEI) Cas 9002-98-6ine mashandisirwo akasiyana-siyana muindasitiri yemachira uye chinhu chakakosha chinoshanda sepolymer. Kukosha kwayo kukuru kuri muhuwandu hwayo hwemacations ane positive charge uye reactivity yakakwira, zvichiita kuti isanganiswe nemafibers ane negative charge, madhayi, uye ma reagents akasiyana-siyana anoshanda, nokudaro ichipa machira hunhu hutsva kana hwakavandudzwa.

Zvinotevera ndizvo zvinonyanya kushandiswa uye kukosha kwePEImuindasitiri yemachira:

Ⅰ. Kudhaya uye Kudhinda: Kuvandudza Mashandiro Emavara uye Hushamwari Hwezvakatipoteredza

PEIZvinovandudza zvakanyanya kudhaya uye kudhinda kwemachira nekusunga zvikamu zvedhayi recationic neanionic, ukuwo zvichideredza kusvibiswa.

1. Kuwedzera Kudzika Kwekudhaya (K/S Kukosha) uye Kusachinja Ruvara:

Machira akaiswa mushonga wePEI akadai sedonje nemvere dzemakwai anoratidza kupinza kwedhayi zvakanyanya, zvichikonzera mavara akadzika uye anopenya. Panguva imwe chete, hunhu hwakasiyana-siyana hwekusachinja ruvara hwemachira akaiswa mushonga neakadhindwa (akadai sekudzivirira kuwacha uye kudzivirira kukwesha) hunovandudzika zvakanyanya. Semuenzaniso, chidzidzo cha2025 chakaratidza kuwedzera kukuru kwehuwandu hwemavara (K/S kukosha) emachira akaiswa mushonga wePEI.

2. Kuwana Kudhinda kweInkjet Yepamberi Pekurapa Pasina Kugeza/Kusageza:

Kushandisa hyperbranchedpolyethyleneimine (PEI)Inki dzedhayi dzakagadziriswa (dzakadai se PEI-R218 inki), kudhinda kwe inkjet kunogona kuitwa zvakananga pamachira asina kugadziriswa, zvichiita kuti dhayi ikwanise kugadzika kupfuura 98.7%. Izvi zvinobvisa saizi yechinyakare yekugeza usati wadhinda uye mushure mekudhinda, zvichideredza zvakanyanya kushandiswa kwemakemikari, mvura, nesimba.

3. Kukurudzira kushandiswa kwemavara echisikigo:

Machira esiriki akagadziriswa nePEI anogona kuvandudza mwero wekudhaya uye simba rekudhaya remadhayi echisikigo akadai securcumin, zvichikurudzira maitiro ekudhaya asingakuvadzi nharaunda.

II. Kupedzisa basa: Kupa machira "masimba makuru"

PEIchinhu chakakosha pakugadzira machira anoshanda, kunyanya anodzivirira moto zvakanyanya.

1.Kunonoka kwemurazvo wepamusoro-soro

Yakapfuma munitrogen,PEIInowanzoshandiswa senzvimbo yekabhoni kana gasi mumasisitimu ekudzivirira moto anopinda mukati medumbu, ichishanda pamwe chete nezvimwe zvinodzivirira moto zvine phosphorus nesilicon.

Machira edonje: Kana akabatanidzwa nezvinhu zvinodzivirira moto zvakaita sephytic acid (PA), uye kuburikidza nekuchinjana kwemaion kana grafting nezvinhu zvinobatanidza, machira anodzivirira moto anoshanda zvakanaka anogona kugadzirwa.

2. Machira eviscose

PEI ine phosphate-esterified, semushonga unodzivirira moto, inogona kuwedzera limiting oxygen index (LOI) yemachira kusvika pa28.9%, zvichiita kuti izvidzime yoga kana moto wabviswa.

3. PA56, PAN, nedzimwe shinda dzekugadzira

Kuburikidza nekubatanidza kana tekinoroji yekuzvisanganisa yega yega, network dzakabatana dzinogona kugadzirwa, zvichiita kuti moto ugare kwenguva refu. Semuenzaniso, jira rePAN rakagadziriswa nePA/PEI/APTES rinoratidza kuwedzera kwe limiting oxygen index (LOI) kubva pa17.4% kusvika pa27.5%, uye rinoratidza hunhu hwakanaka hwekudzora utsi.

4. Hunhu hwekurwisa mabhakitiriya uye antioxidant

PEI pachayo pamwe chete nesimbi dzayo dzinobatanidza zvinhu (dzakadai sePEI-Cu) dzine hunhu hwekurwisa mabhakitiriya. Machira edonje akarapwa nePEI akaratidza hunhu hwe83.33% hwekurwisa mabhakitiriya uye 74.2% hwekurwisa mabhakitiriya mukushandiswa kwetriboelectric nanogenerator (T-TENG).

5. Kufambiswa Kwemhepo Kwakawedzerwa uye Hunhu Hwakasimba:

Kudzivirira Magetsi: shinda yepolyamide (PA) yakagadziriswa nePEI inosimbisa zvakanyanya kunamira kwe graphene oxide (GO) coating. shinda yekufambisa inoguma inoramba ichifambisa magiya e4.7 × 10³ S/m mushure mekukombama ka10,000, zvichiita kuti electromagnetic shielding ishande zvakanaka kusvika ku66.7 dB.

6. Hunhu Husingachinji

PEIinowedzera kushanduka kwemvura mumachira, zvichideredza kuunganidzwa kwemagetsi asingachinji.

7. Makushe Anodzivirira kukwesha

Maitiro ekugadzirisa anoenderera mberi ekudzivirira kupwanyika uchishandisa potassium persulfate (PMS)-PEI mumatanho maviri inzira isina chlorine uye isingakuvadzi nharaunda.

8. Kunatsiridza Kunyorova uye Kunyungudika Kwemvura

PEIKurapa kunovandudza zvakanyanya kunyorova kwemafibers anonyungudutsa mumvura akadai semvere dzemakwai, uye PEI ine huremu hwakawanda ichiratidza mhedzisiro iri nani.

III. Kugadziriswa kwenzvimbo: Kuvaka "bhiriji" rinoshanda

PEIinogona kushandiswa se "bridge layer" kana "anchoring agent" yekugadzirisa fiber yakadzika.

1. Kuvandudza Simba reKuputira

Sechifukidziro chepasi, PEI inogona kuvandudza zvakanyanya kusimba kwekutakura uye kubatana kwezvinhu zvinoshanda (zvakadai seMXene (Ti₃C₂Tₓ) uye graphene oxide (GO)) pamusoro pefiber.

2. Kugadzirira Zvikamu Zvinoshanda

Inogona kushandiswa kugadzira zvinhu zvakaita sePEI@PLA airgels zvinoshandiswa pakugadzira dye adsorption.

3. Kuisa Makemikoro Ekugadzirisa Makemikari

Senzira yekubatanidza simbi, inogona kushandiswa kurapa machira edonje, zvichiita kuti copper sulfide (CuS) ikwanise kuputira pamusoro payo, zvichiita kuti ikwanise kufambisa mvura.

Ⅳ. Pfupiso

Polyethyleneimine (PEI)ine kukosha muindasitiri yemachira muzvikamu zvese, kubva pakudhaya uye kupedzisa kushanda kwayo kusvika pakugadzira zvinhu zvinosanganisa mashandiro epamusoro. Haisi "chinosimudzira" chete pakuvandudza mashandiro uye hushamwari hwemachira echinyakare (donje, mvere dzemakwai, sirika), asiwo chinhu chakakosha pakugadzira machira emazuva ano akangwara, anodzivirira, uye anoshanda zvakanyanya.

Zvinofanira kucherechedzwa kuti kushandiswa kwePEIine hukama hwakasimba nematanho ayo ekuvaka akadai sehuremu hwemamorekuru uye mwero wemapazi. Mukushanda kwayo, zvakakosha kuisarudza nekuigadzirisa zvichienderana nemaitiro chaiwo.
