Polyethyleneimine (PEI) Cas 9002-98-6Ili ndi ntchito zosiyanasiyana mumakampani opanga nsalu ndipo ndi chinthu chofunikira kwambiri chogwiritsidwa ntchito ndi polima. Mtengo wake waukulu uli mu kuchuluka kwa ma cation omwe ali ndi mphamvu zabwino komanso kusinthasintha kwakukulu, zomwe zimapangitsa kuti igwirizane ndi ulusi woipa, utoto, ndi zinthu zosiyanasiyana zogwirira ntchito, motero imapatsa nsalu zinthu zatsopano kapena zowonjezera.

Zotsatirazi ndi ntchito zazikulu ndi makhalidwe aPEImu makampani opanga nsalu:

Ⅰ. Kupaka Utoto ndi Kusindikiza: Kupititsa patsogolo Maonekedwe a Utoto ndi Ubwino wa Chilengedwe

PEIZimathandiza kwambiri kupenta ndi kusindikiza nsalu mwa kumangirira zigawo zake za utoto wa cationic ndi anionic, komanso kuchepetsa kuipitsa.

1. Kuzama Kwambiri kwa Utoto (K/S Value) ndi Kusagwa kwa Mtundu:

Nsalu zokonzedwa ndi PEI monga thonje ndi ubweya zimawonetsa kuyamwa kwa utoto kwambiri, zomwe zimapangitsa kuti mitundu ikhale yozama komanso yowala. Nthawi yomweyo, mitundu yosiyanasiyana ya nsalu zopakidwa utoto ndi zosindikizidwa (monga kukana kusamba ndi kukana kukanda) imakula kwambiri. Mwachitsanzo, kafukufuku wa 2025 adawonetsa kuwonjezeka kwakukulu kwa mphamvu ya utoto (K/S value) wa nsalu zokonzedwa ndi PEI.

2. Kukwanitsa Kusindikiza Inkjet Yopanda Kusamba/Yopanda Kusamba:

Kugwiritsa ntchito hyperbranchedpolyethyleneimine (PEI)Inki yosinthira utoto (monga inki ya PEI-R218), kusindikiza kwa inki kumatha kuchitika mwachindunji pa nsalu zosakonzedwa, zomwe zimapangitsa kuti utoto ukhale woposa 98.7%. Izi zimachotsa kukula kwachikhalidwe kosindikiza ndi kutsuka pambuyo posindikiza, zomwe zimachepetsa kwambiri kugwiritsa ntchito mankhwala, madzi, ndi mphamvu.

3. Kulimbikitsa kugwiritsa ntchito utoto wachilengedwe:

Nsalu za silika zosinthidwa ndi PEI zitha kupititsa patsogolo bwino kuchuluka kwa utoto ndi mphamvu ya utoto wachilengedwe monga curcumin, zomwe zimapangitsa kuti utotowo ukhale wosawononga chilengedwe.

II. Kumaliza ntchito: Kupatsa nsalu "mphamvu zazikulu"

PEIndi chinthu chofunikira kwambiri popanga nsalu zogwira ntchito, makamaka zomwe zimapangitsa kuti moto usamayaka bwino.

1.Kulephera kwa lawi kwambiri

Wolemera mu nayitrogeni,PEInthawi zambiri amagwiritsidwa ntchito ngati gwero la kaboni kapena mpweya m'machitidwe oletsa moto omwe amalowa m'mimba, kugwira ntchito mogwirizana ndi zinthu zina zoletsa moto zomwe zili ndi phosphorous ndi silicon.

Nsalu za thonje: Zikaphatikizidwa ndi zinthu zoletsa moto zochokera ku bio-based monga phytic acid (PA), komanso kudzera mu kusinthana kwa ma ion kapena grafting ndi zinthu zolumikizirana, zophimba zoletsa moto zogwira ntchito bwino kwambiri zitha kupangidwa.

2. Nsalu za viscose

PEI yopangidwa ndi phosphate, monga choletsa moto, imatha kuwonjezera kuchuluka kwa mpweya wochepa (LOI) wa nsalu kufika pa 28.9%, zomwe zimapangitsa kuti izizimitse yokha moto ukachotsedwa.

3. PA56, PAN, ndi ulusi wina wopangidwa

Kudzera mu ukadaulo wophatikiza kapena ukadaulo wodzipangira wokha, maukonde olumikizana amatha kupangidwa, zomwe zimapangitsa kuti moto ukhale wokhalitsa. Mwachitsanzo, nsalu ya PAN yomwe yathandizidwa ndi PA/PEI/APTES imasonyeza kuwonjezeka kwa oxygen index (LOI) kuchokera pa 17.4% mpaka 27.5%, ndipo imasonyeza mphamvu zabwino kwambiri zoletsa utsi.

4. Mphamvu zoletsa mabakiteriya ndi zoletsa ma antioxidants

PEI yokha ndi mankhwala ake ogwirizanitsa zitsulo (monga PEI-Cu) ali ndi mphamvu zotsutsana ndi mabakiteriya. Nsalu za thonje zokonzedwa ndi PEI zinawonetsa mphamvu zotsutsana ndi mabakiteriya 83.33% ndi mphamvu zotsutsana ndi mabakiteriya 74.2% mu ntchito za triboelectric nanogenerator (T-TENG).

5. Kupititsa patsogolo Mayendedwe ndi Katundu Wosasinthika:

Kuteteza Magetsi: Ulusi wa polyamide (PA) wosinthidwa ndi PEI umalimbitsa kwambiri kumatirira kwa utoto wa graphene oxide (GO). Ulusi wotulutsa mpweya womwe umachokera umasunga mphamvu yoyendetsa mpweya ya 4.7 × 10³ S/m pambuyo pa ma bend 10,000, zomwe zimapangitsa kuti chitetezo chamagetsi chikhale cholimba mpaka 66.7 dB.

6. Katundu Wosasinthasintha

PEIkumawonjezera kusinthasintha kwa madzi m'nsalu, kuchepetsa kuchuluka kwa magetsi osasinthasintha.

7. Ubweya Woletsa Kuchotsa Ubweya

Njira yomaliza yolimbana ndi kuzizira pogwiritsa ntchito potaziyamu persulfate (PMS)-PEI m'njira ziwiri ndi njira yopanda chlorine komanso yoteteza chilengedwe.

8. Kunyowa Kwabwino ndi Kusinthasintha kwa Madzi

PEIChithandizochi chimathandiza kwambiri kuti ulusi wonyowa m'madzi monga ubweya ukhale wonyowa, ndipo PEI yolemera kwambiri imasonyeza zotsatira zabwino.

III. Kusintha malo: Kupanga "mlatho" wogwira ntchito

PEIingagwiritsidwe ntchito ngati "cholumikizira" kapena "chothandizira kukhazikika" pakusintha ulusi wozama.

1. Kulimbitsa Mphamvu Yophimba

Monga chophimba cha maziko, PEI imatha kusintha kwambiri mphamvu yonyamula ndi yolumikizira ya zinthu zogwirira ntchito (monga MXene (Ti₃C₂Tₓ) ndi graphene oxide (GO)) pamwamba pa ulusi.

2. Kukonzekera Zosakaniza Zogwira Ntchito

Ingagwiritsidwe ntchito pokonza zinthu monga ma PEI@PLA airgels kuti agwiritsidwe ntchito monga kusakaniza utoto.

3. Chophimba cha Mankhwala Chothandizira

Monga chothandizira kusakaniza, chingagwiritsidwe ntchito pochiza ulusi wa thonje, zomwe zimathandiza kuti copper sulfide (CuS) ipange pamwamba pake, zomwe zimapangitsa kuti pakhale mphamvu yoyendetsa mpweya.

Chidule cha Ⅳ

Polyethyleneimine (PEI)Ili ndi phindu pamakampani opanga nsalu m'magawo onse, kuyambira pakupaka utoto ndi kumaliza bwino mpaka kukonzekera zinthu zophatikizika bwino kwambiri. Sikuti ndi "chothandizira" chokha pakukweza magwiridwe antchito komanso kusamala chilengedwe cha nsalu zachikhalidwe (thonje, ubweya, silika), komanso ndi chinthu chofunikira kwambiri popanga nsalu zamakono zanzeru, zoteteza, komanso zogwira ntchito bwino.

Tiyenera kudziwa kuti zotsatira za kugwiritsa ntchitoPEIimagwirizana kwambiri ndi kapangidwe kake monga kulemera kwa mamolekyulu ndi kuchuluka kwa nthambi. Mu ntchito zenizeni, ndikofunikira kusankha ndikukonza molingana ndi njira yeniyeni.
