Ngo-2025, ishishini lokugquma liyakhawuleza ukuya kwiinjongo ezimbini “zotshintsho oluluhlaza” kunye “nokuphucula ukusebenza.” Kwiindawo zokugquma ezikumgangatho ophezulu ezinje ngeemoto kunye nohambo lukaloliwe, iidyasi eziphuma emanzini ziye zavela "kwiindlela ezizezinye" ukuya "kukhetho oluqhelekileyo" ngenxa yokukhutshwa kwazo okuphantsi kwe-VOC, ukhuseleko, kunye nokungabi natyhefu. Nangona kunjalo, ukuhlangabezana neemfuno zeemeko zesicelo esinzima (umzekelo, ukufuma okuphezulu kunye nokuhlwa okuqinileyo) kunye neemfuneko eziphezulu zabasebenzisi zokomelela nokusebenza kakuhle kobugcisa, ukuqhubela phambili kobuchwepheshe kwiingubo ze-polyurethane yamanzi (WPU) ziyaqhubeka zihamba. Ngo-2025, iinguqulelo zeshishini kusetyenziso lwefomula, ukuguqulwa kweekhemikhali, kunye noyilo olusebenzayo kuye kwafaka amandla amatsha kweli candelo.
Ukugxininisa iNkqubo eSiseko: Ukusuka “kuLungelelaniso lweReyishini” ukuya “kuLungelelaniso lweNtsebenzo”
Njengoko "inkokeli yokusebenza" phakathi kweengqungquthela zamanzi zangoku, i-polyurethane yamanzi yamacandelo amabini (i-WB 2K-PUR) ijongene nomngeni ongundoqo: ukulinganisa umlinganiselo kunye nokusebenza kweenkqubo ze-polyol. Kulo nyaka, amaqela ophando aqhube uphando olunzulu kwiimpembelelo ze-synergistic ze-polyether polyol (PTMEG) kunye ne-polyester polyol (P1012).
Ngokwemveli, ipolyester polyol yongeza ukomelela komatshini kunye noxinaniso ngenxa yebhondi ye-hydrogen exineneyo, kodwa ukongezwa okugqithisileyo kunciphisa ukuxhathisa kwamanzi ngenxa ye-hydrophilicity eyomeleleyo yamaqela e-ester. Iimvavanyo ziqinisekisiwe ukuba xa i-P1012 i-akhawunti ye-40% (g / g) yenkqubo ye-polyol, "ibhalansi yegolide" ifezekisiwe: iibhondi ze-hydrogen zandisa ukuxinwa kwe-crosslink ngokomzimba ngaphandle kwe-hydrophilicity egqithisileyo, ukwandisa ukusebenza okubanzi kwe-coating-kuquka ukuxhathisa ityuwa yokutshiza, ukuxhathisa kwamanzi, kunye namandla okuqina. Esi sigqibo sinika isikhokelo esicacileyo se-WB 2K-PUR yoyilo lwefomula esisiseko, ngakumbi kwiimeko ezifana ne-chassis yemoto kunye nentsimbi yentsimbi yesithuthi sikaloliwe ezifuna ukusebenza koomatshini kunye nokuxhathisa ukubola.
"Ukudibanisa ukuqina kunye nokuguquguquka": Ukuguqulwa kweMichiza kuvula iMida emitsha yokuSebenza
Ngelixa ulungelelwaniso olusisiseko “lulungelelwaniso olulungileyo,” ukuguqulwa kweekhemikhali kubonisa “umgangatho wokutsiba” kwi-polyurethane yamanzi. Iindlela ezimbini zohlengahlengiso ziye zagqama kulo nyaka:
Umendo 1: Ukuphuculwa kwe-Synergistic kunye nePolysiloxane kunye ne-Terpene Derivatives
Ukudityaniswa kwe-low-surface-energy polysiloxane (PMMS) kunye ne-hydrophobic terpene derivatives inika iWPU ngeempawu ezimbini "ze-superhydrophobicity + ukuqina okuphezulu." Abaphandi balungiselela i-hydroxyl-terminated polysiloxane (PMMS) besebenzisa i-3-mercaptopropylmethyldimethoxysilane kunye ne-octamethylcyclotetrasiloxane, emva koko bahlonyelwe i-isobornyl acrylate (i-derivative of biomass-derived camphene) kwi-PMMS amatyathanga asecaleni nge-UV-initiated form-polyxane thiol-PMMS esekelwe kwi-polysipene reaction reaction.
I-WPU elungisiweyo ibonise ukuphucuka okumangalisayo: i-angle yoqhagamshelwano lwamanzi e-static yatsiba ukusuka ku-70.7 ° ukuya kwi-101.2 ° (isondela kwi-lotus-like superhydrophobicity), ukufunxa kwamanzi kwehla ukusuka kwi-16.0% ukuya kwi-6.9%, kwaye amandla okuqina anyuka ukusuka kwi-4.70MPa ukuya kwi-8.82MPa ye-ringer ngenxa ye-ringer ye-ringer. Uhlalutyo lwe-Thermogravimetric lubonakalise ukuzinza okuphuculweyo kwe-thermal. Le teknoloji inikezela ngesisombululo esihlanganisiweyo "sokuchasana nokuchasana + kwemozulu" kwiindawo zangaphandle zokuhamba ngololiwe ezifana neepaneli zophahla kunye neengubo ezisecaleni.
Umendo we-2: I-Polyimine Crosslinking yenza "Ukuziphilisa" iTekhnoloji
Ukuziphilisa kuye kwavela njengetekhnoloji edumileyo kwiingubo, kwaye uphando lwalo nyaka luyidibanise nokusebenza koomatshini beWPU ukuphumeza impumelelo ephindwe kabini “kwindlela yokusebenza ephezulu + yokukwazi ukuziphilisa.” I-WPU ye-Crosslinked elungiselelwe nge-polybutylene glycol (PTMG), isophorone diisocyanate (IPDI), kunye ne-polyimine (PEI) njenge-crosslinker ebonisa iimpawu ezichukumisayo ze-mechanical: amandla e-tensile ye-17.12MPa kunye ne-elongation kwi-break ye-512.25% (kufuphi ne-rubber flexibility).
Okubaluleke kakhulu, ifezekisa ukuziphilisa okupheleleyo kwiiyure ze-24 kwi-30 ° C-ukubuyisela kwi-3.26MPa amandla okuqina kunye ne-450.94% elongation emva kokulungiswa. Oku kuyenza ilunge kakhulu kwiindawo ezithanda ukukrweleka njengeebhampa zemoto kunye nezangaphakathi zothutho lukaloliwe, inciphisa kakhulu iindleko zolondolozo.
"I-Nanoscale Intelligent Control": "I-Surface Revolution" ye-Anti-Fouling Coatings
I-Anti-graffiti kunye nokucocwa lula ziimfuno eziphambili zeengubo eziphezulu. Kulo nyaka, i-coating-resistant-resistant coating (NP-GLIDE) esekelwe "kwi-liquid-like PDMS nanopools" yatsala ingqalelo. Umgaqo wayo ongundoqo ubandakanya ukuxhunyelelwa i-polydimethylsiloxane (PDMS) emacaleni amatyathanga kwi-polyol backbone yamanzi ehlakazekayo nge-graft copolymer polyol-g-PDMS, eyenza "ii-nanopools" ezincinci kune-30nm ububanzi.
Ukutyetyiswa kwe-PDMS kwezi nanopools kunika i-coating "efana ne-liquid" ebusweni-zonke ii-liquids zokuvavanya kunye noxinzelelo lwaphezulu ngaphezu kwe-23mN / m (umzekelo, ikofu, i-oil stains) isilayidi ngaphandle kokushiya amanqaku. Ngaphandle kobunzima be-3H (kufuphi neglasi eqhelekileyo), i-coating igcina umsebenzi obalaseleyo wokuchasana nokungcola.
Ukongezelela, isicwangciso se-anti-graffiti se-anti-graffiti "isithintelo somzimba + esincinci" sicetywayo: ukwazisa i-IPDI trimer kwi-HDT-based polyisocyanate ukunyusa ubuninzi befilimu kunye nokukhusela ukungena kwegraffiti, ngelixa ulawula ukufuduka kwe-silicone / amacandelo e-fluorine ukuqinisekisa ixesha elide eliphantsi kwamandla aphantsi. Idityaniswe ne-DMA (i-Dynamic Mechanical Analysis) yolawulo oluchanekileyo lwe-crosslink density kunye ne-XPS (i-X-ray Photoelectron Spectroscopy) ye-interface migration characterization, obu buchwephesha bulungele ushishino kwaye kulindeleke ukuba lube luphawu olutsha lokuchasana nokungcola kwipeyinti yemoto kunye ne-3C yeemveliso zemveliso.
Ukuqukumbela
Ngo-2025, itekhnoloji yokugquma iWPU isuka "kuphuculo lomsebenzi omnye" ukuya "kudityaniso lwemisebenzi emininzi." Nokuba kungokwenziwa kwefomula esisiseko, ukuphumelela kohlengahlengiso lweekhemikhali, okanye uyilo oluyilwayo olusebenzayo, eyona ngqiqo ingundoqo ijikeleza ekunxibelelaneni "nobuhlobo bendalo" kunye "nokusebenza okuphezulu." Kumashishini afana neemoto kunye nezothutho zikaloliwe, le nkqubela phambili yetekhnoloji ayandisi nje kuphela ixesha lokuphila kunye nokunciphisa iindleko zokulungisa kodwa ikwaqhuba uphuculo oluphindwe kabini "kwimveliso eluhlaza" kunye "namava omsebenzisi aphezulu."
