Mu 2025, inganda zitwikiriye zirihuta kugera ku ntego ebyiri zo “guhindura icyatsi” no “kuzamura imikorere.” Mu bice byo hejuru cyane nko gutwika amamodoka na gari ya moshi, ubwikorezi bwo mu mazi bwavuye mu "buryo butandukanye" buhinduka "guhitamo inzira nyamukuru" bitewe n’ibyuka bihumanya ikirere cya VOC, umutekano, ndetse n’uburozi. Ariko rero, kugirango uhuze ibyifuzo bya sisitemu ikarishye (urugero, ubuhehere bwinshi no kwangirika gukomeye) hamwe n’ibisabwa cyane by’abakoresha mu gutwikira igihe no gukora, iterambere mu ikoranabuhanga mu mavuta ya polyurethane (WPU) akomeje kwihuta. Mu 2025, udushya tw’inganda mu kunoza imikorere, guhindura imiti, no gushushanya imikorere byinjije imbaraga muri uru rwego.
Gutezimbere Sisitemu Yibanze: Kuva "Guhuza Igipimo" kugeza "Kuringaniza Imikorere"
Nka "umuyobozi wimikorere" mubitambaro byamazi byubu, polyurethane yibice bibiri byamazi (WB 2K-PUR) ihura ningorabahizi: kuringaniza igipimo n'imikorere ya sisitemu ya polyol. Uyu mwaka, amatsinda yubushakashatsi yakoze ubushakashatsi bwimbitse ku ngaruka ziterwa na polyether polyol (PTMEG) na polyester polyol (P1012).
Ubusanzwe, polyester polyol yongerera imbaraga ubukanishi nubucucike bitewe na hydrogène ya hydrogène ya intermolecular, ariko kwiyongera cyane bigabanya kurwanya amazi bitewe na hydrophilique ikomeye yitsinda rya ester. Ubushakashatsi bwagaragaje ko iyo P1012 igizwe na 40% (g / g) ya sisitemu ya polyol, hagerwaho “impirimbanyi ya zahabu”: imigozi ya hydrogène yongerera ubwuzuzanye bw’umubiri nta hydrophilique ikabije, bigahindura imikorere yuzuye - harimo kurwanya umunyu, kurwanya amazi, n'imbaraga zikaze. Uyu mwanzuro utanga ubuyobozi busobanutse kubushakashatsi bwibanze bwa WB 2K-PUR, cyane cyane kubintu nka chassis yimodoka hamwe nibyuma bya gari ya moshi bisaba imikorere yubukanishi no kurwanya ruswa.
“Guhuza Rigidity na Flexibility”: Guhindura imiti bifungura imipaka mishya
Mugihe ibipimo fatizo bitezimbere ari "ihinduka ryiza," guhindura imiti byerekana "gusimbuka kwiza" kuri polyurethane ikomoka kumazi. Inzira ebyiri zo guhindura zagaragaye muri uyu mwaka:
Inzira ya 1: Gutezimbere Gukomatanya hamwe na Polysiloxane na Terpene
Ihuriro ry’ingufu nkeya-polysiloxane (PMMS) hamwe n’ibikomoka kuri hydrophobique terpene biha WPU ibintu bibiri bya “superhydrophobicity + gukomera cyane.” Abashakashatsi bateguye hydroxyl yarangijwe na polysiloxane (PMMS) bakoresheje 3-mercaptopropylmethyldimethoxysilane na octamethylcyclotetrasiloxane, hanyuma bashiramo isobornyl acrylate (ikomoka kuri biomass ikomoka kuri camphene) ikoresheje iminyururu ya PMMS ikoresheje poli-terox ya thiol-ene.
WPU yahinduwe yerekanye iterambere ridasanzwe: inguni ihuza amazi ihagaze yavuye kuri 70.7 ° igera kuri 101.2 ° (yegera amababi ya lotus imeze nka superhydrophobicity), iyinjizwa ryamazi ryamanutse riva kuri 16.0% rigera kuri 6.9%, kandi imbaraga zikaze ziva kuri 4.70MPa zigera kuri 8.82MPa kubera imiterere yimpeta ya terpene. Isesengura rya Thermogravimetric naryo ryagaragaje kuzamura ubushyuhe bwumuriro. Iri koranabuhanga ritanga igisubizo "anti-fouling + irwanya ikirere" igisubizo cyibice byo hanze ya gari ya moshi nkibisenge byamazu hamwe nijipo yo kuruhande.
Inzira ya 2: Guhuza Polyimine Bituma Ikoranabuhanga "Kwikiza"
Kwikiza byagaragaye nk'ikoranabuhanga rizwi cyane mu gutwikira, kandi ubushakashatsi bw'uyu mwaka bwahujije n'imikorere ya WPU kugira ngo bugere ku ntera ebyiri mu “gukora cyane + ubushobozi bwo kwikiza.” WPU ihuza WPU yateguwe na polybutylene glycol (PTMG), isophorone diisocyanate (IPDI), na polyimine (PEI) nka crosslinker yerekanaga imiterere yubukanishi: imbaraga zingana na 17.12MPa no kurambura kumena 512.25% (hafi ya rubber yoroheje).
Icy'ingenzi, igera ku kwikiza byuzuye mu masaha 24 kuri 30 ° C-igarura imbaraga za 3.26MPa zingana na 450,94% nyuma yo gusanwa. Ibi bituma bikwiranye cyane nibice bikunda gushushanya nka bamperi yimodoka hamwe na gari ya moshi imbere, bikagabanya cyane amafaranga yo kubungabunga.
“Nanoscale Igenzura ryubwenge”: “Impinduramatwara yo hejuru” yo kurwanya ibishishwa
Anti-graffiti no guhanagura byoroshye nibintu byingenzi bisabwa hejuru. Uyu mwaka, igipfunyika kidashobora kwangirika (NP-GLIDE) gishingiye kuri “amazi ameze nka PDMS nanopools” cyashimishije abantu. Ihame ryibanze ryayo ririmo guhuza iminyururu ya polydimethylsiloxane (PDMS) kumurongo wumugozi wa polyol ukwirakwiza amazi ukoresheje graft copolymer polyol-g-PDMS, ugakora "nanopools" ntoya ya 30nm ya diameter.
Gukungahaza kwa PDMS muri iyi nanopool biha igifuniko hejuru "isa n'amazi" - amazi yose yipimisha afite uburemere hejuru ya 23mN / m (urugero, ikawa, irangi ryamavuta) iranyerera idasize ibimenyetso. Nubwo ubukana bwa 3H (hafi yikirahuri gisanzwe), igifuniko gikomeza imikorere myiza yo kurwanya ikosa.
Byongeye kandi, hashyizweho ingamba za "barrière physique + isuku yoroheje" yo kurwanya graffiti: kwinjiza trimeri ya IPDI muri polyisocyanate ishingiye kuri HDT kugirango hongerwe ubukana bwa firime no kwirinda graffiti kwinjira, mugihe hagenzurwa iyimuka ryibice bya silicone / fluor kugirango habeho ingufu ndende zo hasi. Hamwe na DMA (Dynamic Mechanical Analysis) kugirango igenzurwe neza neza na XPS (X-ray Photoelectron Spectroscopy) kugirango imiterere yimuka yimiterere, iri koranabuhanga ryiteguye mu nganda kandi biteganijwe ko rizaba igipimo gishya cyo kurwanya ikosa ry’irangi ry’imodoka hamwe n’ibicuruzwa 3C.
Umwanzuro
Muri 2025, tekinoroji ya WPU iva mu "kunoza imikorere imwe" ikajya "guhuza ibikorwa byinshi." Haba binyuze muburyo bwibanze bwo gutezimbere, guhindura imiti, cyangwa guhanga udushya, imikorere yibanze ishingiye ku guhuza “ibidukikije byangiza ibidukikije” n '“imikorere myiza.” Ku nganda nko gutwara ibinyabiziga na gari ya moshi, iri terambere mu ikoranabuhanga ntirongerera igihe cyo gutwikira ubuzima no kugabanya amafaranga yo kubungabunga, ahubwo rinateza imbere ibyiciro bibiri mu “gukora icyatsi kibisi” na “uburambe bwo mu rwego rwo hejuru.”
