Muna 2025, indasitiri yekupfeka iri kukurumidza kuenda kuzvinangwa zviviri zve "shanduko yegirinhi" uye "kusimudzira kwekuita." Munzvimbo dzepamusoro-soro dzekupfekedza senge mota uye njanji yekufambisa, machira emvura akashanduka kubva kune "dzimwe sarudzo" kuenda ku "mainstream sarudzo" nekuda kwekushomeka kwavo kweVOC kuburitsa, chengetedzo, uye isiri-chepfu. Zvakadaro, kuzadzisa zvinodikanwa zvemashandisirwo akaomarara (semuenzaniso, kunyorova kwepamusoro uye kukora kwakasimba) uye zvinodiwa nevashandisi zvakanyanya zvekusimba uye kushanda nesimba, tekinoroji mumachira ane polyurethane (WPU) anoenderera mberi. Muna 2025, hunyanzvi hweindasitiri mune formula optimization, gadziriso yemakemikari, uye dhizaini inoshanda zvakapinza hutsva hutsva muchikamu ichi.
Kudzamisa Sistimu Yekutanga: Kubva ku "Ratio Tuning" kuenda ku "Performance Balance"
Se "mutungamiri wekuita" pakati pemajasi emvura aripo, maviri-echikamu waterborne polyurethane (WB 2K-PUR) anotarisana nedambudziko guru: kuenzanisa reshiyo uye kushanda kwe polyol masisitimu. Gore rino, zvikwata zvekutsvagisa zvakaita ongororo yakadzama mune synergistic mhedzisiro yepolyether polyol (PTMEG) uye polyester polyol (P1012).
Sechinyakare, polyester polyol inosimudzira coating mechanical simba uye density nekuda kwe dense intermolecular hydrogen bond, asi kuwedzera zvakanyanya kunoderedza kuramba kwemvura nekuda kwekusimba kwehydrophilicity yemapoka ester. Maedzo akaoneswa kuti kana P1012 inobata 40% (g/g) ye polyol system, "golden balance" inowanikwa: ma hydrogen bond anowedzera kusimba kwemuviri wemuchinjiko pasina hydrophilicity yakawandisa, achinatsiridza kuita kwakazara kwekuvhara-kusanganisira munyu kupfapfaidza kuramba, kusagadzikana kwemvura, uye kusimba kwesimba. Mhedziso iyi inopa kutungamira kwakajeka kweWB 2K-PUR basic formula dhizaini, kunyanya kune mamiriro akaita semotokari chassis uye njanji yemotokari simbi zvikamu zvinoda zvese ma mechanic performance uye corrosion resistance.
"Kubatanidza Kusimba uye Kuchinja": Kemikari Kugadziriswa Kunovhura Mitsva Yekushanda Miganhu
Nepo basic ratio optimization iri "chakanaka gadziriso," gadziriso yekemikari inomiririra "hunhu hwekusvetuka" hwemvura ine polyurethane. Nzira mbiri dzekugadzirisa dzakamira gore rino:
Nzira 1: Synergistic Enhancement nePolysiloxane uye Terpene Derivatives
Iko kusanganiswa kwepasi-pasi-simba polysiloxane (PMMS) uye hydrophobic terpene zvinobva kunopa WPU ine mbiri mbiri ye "superhydrophobicity + yakakwirira kuomarara." Vatsvakurudzi vakagadzira hydroxyl-terminated polysiloxane (PMMS) vachishandisa 3-mercaptopropylmethyldimethoxysilane uye octamethylcyclotetrasiloxane, ndokuzobatanidzwa isobornyl acrylate (inotorwa kubva kubiomass-derived camphene) pamaketani ekumativi ePMMS kuburikidza neUV-initiated form-based thiol-iterIneipene reaction (poly-MS)
Iyo WPU yakagadziridzwa yakaratidza kuvandudzwa kunoshamisa: static water contact angle yakasvetuka kubva 70.7 ° kusvika 101.2 ° (inosvika lotus-seshizha-sesuperhydrophobicity), kunyura kwemvura kwakadzikira kubva pa16.0% kusvika 6.9%, uye simba rekusimba rakakwira kubva ku4.70MPa kuenda ku8.82MPa yerigidpeter. Ongororo yeThermogravimetric yakaratidzawo yakawedzera kugadzikana kwekupisa. Iyi tekinoroji inopa yakabatanidzwa "anti-fouling + mamiriro ekunze-resistant" mhinduro yenjanji yekunze zvikamu zvakaita sepadenga mapaneru uye masiketi epadivi.
Nzira 2: Polyimine Crosslinking Inogonesa "Kuzviporesa" Technology
Kuzvirapa kwakabuda sehunyanzvi hwekugadzira machira, uye tsvakiridzo yegore rino yakaisanganisa neWPU's mechanic performance kuti iwane mabhindauko maviri mu "high performance + yekuzvirapa." Crosslinked WPU yakagadzirwa ne polybutylene glycol (PTMG), isophorone diisocyanate (IPDI), uye polyimine (PEI) se crosslinker yakaratidza zvinoyevedza mechanical properties: tensile simba re 17.12MPa uye elongation pakuputsika kwe512.25% (pedyo nerubha kushanduka).
Nehurombo, inowana kuzvirapa kuzere mumaawa makumi maviri nemana pa 30 ° C-kudzoreredza ku 3.26MPa kusimba simba uye 450.94% kureba mushure mekugadzirisa. Izvi zvinoita kuti ive yakanyatsokodzera kukwenya-zvinoita senge mabumper emotokari uye njanji yekufambisa yemukati, ichideredza zvakanyanya mari yekugadzirisa.
"Nanoscale Intelligent Control": "Surface Revolution" yeAnti-Fouling Coatings
Anti-graffiti uye nyore-kuchenesa ndizvo zvakakosha zvinodiwa zvekupfava kwepamusoro. Gore rino, iyo fouling-resistant coating (NP-GLIDE) yakavakirwa pa "liquid-senge PDMS nanopools" yakakwezva kutarisa. Musimboti wayo wepakati unosanganisira kubatanidza polydimethylsiloxane (PDMS) padivi cheni pamvura-inoparadzirwa polyol musana kuburikidza negraft copolymer polyol-g-PDMS, ichigadzira "nanopools" idiki pane 30nm padhayamita.
Kuwedzera kwePDMS mune idzi nanopools kunopa iyo yekuputira iyo "mvura-yakafanana" pamusoro-zvese zvinwiwa zvekuedza zvine kusimba kwepamusoro pamusoro pe23mN/m (semuenzaniso, kofi, tsvina yemafuta) inotsvedza isina kusiya mamakisi. Kunyangwe kuoma kwe3H (padyo negirazi rakajairwa), iyo yekupfeka inochengetedza yakanakisa anti-fouling kuita.
Uyezve, "chipingamupinyi chemuviri + kuchenesa zvishoma" anti-graffiti zano rakarongwa: kuunza IPDI trimer muHDT-based polyisocyanate kuti iwedzere kusimba kwefirimu uye kudzivirira kupinza kwegraffiti, apo ichidzora kutama kwesilicone / fluorine zvikamu kuti zvive nechokwadi chekugara kwenguva refu pasi pesimba. Yakasanganiswa neDMA (Dynamic Mechanical Analysis) yechaiyo crosslink density control uye XPS (X-ray Photoelectron Spectroscopy) yechimiro chekufamba-famba, tekinoroji iyi yakagadzirira indasitiri uye inotarisirwa kuve mucherechedzo mutsva weanti-fouling mupendi yemotokari uye 3C chigadzirwa casings.
Mhedziso
Muna 2025, tekinoroji yeWPU yekupfekedza iri kufamba kubva ku "single-performance improvement" kuenda ku "multi-functional integration." Kunyangwe kuburikidza neiyo basic formula optimization, makemikari ekugadzirisa mabhindauko, kana dhizaini dhizaini, musimboti wepfungwa unoenderana nekubatanidza "kushamwaridzana kwezvakatipoteredza" uye "kushanda kwepamusoro." Kune maindasitiri akaita semotokari uye njanji, kufambira mberi kwetekinoroji hakungowedzere hupenyu hwekubatisa uye kuderedza mutengo wekugadzirisa, asiwo kunofambisa kukwidziridzwa kwakapetwa mu "green kugadzira" uye "yepamusoro-yekupedzisira mushandisi ruzivo."
