Polyurethane-ka Waterbane waa nooc cusub oo nidaam polyurethane ah oo biyaha u adeegsada halkii ay ka heli lahaayeen solvents dabiici ah oo dhexdhexaad ah. Waxay leedahay faa'iidooyinka wasakheynta, badbaadada iyo isku halaynta, guryaha farsamada wanaagsan, waafaqsanaanta wanaagsan, iyo wax ka badalida fudud.
Si kastaba ha noqotee, agabyada polyurethane waxay sidoo kale la kulmaan iska caabin biyo oo liita, iska caabbi kuleylka, iyo caabbinta dareeraha ah ee caabbinta sababtuna tahay la'aanta dammaanadda isku xirka isku xirka isku xira.
Sidaa darteed, waxaa lagama maarmaan ah in la wanaajiyo oo la wanaajiyo astaamaha kala duwan ee codbixinta ee Polyurethane iyadoo la soo bandhigayo monomerione-ka shaqeeya sida fororiosilicone-ka dabiiciga ah sida folosilicone-ka dabiiciga ah, epry resin, estaroolka acrylic, iyo nanomateric.
Waxaa ka mid ah iyaga, nanimet wax laga beddelay agabyada polyurethane waxay si weyn u hagaajin kartaa guryaha farsamada, xidha caabbinta, iyo xasilloonida kuleylka. Qaababka wax ka badalida waxaa ka mid ah habka isu-tagga ah ee isku-darka, habka 'polymerization', habka isku-darka, iwm.
Nano Silica
Sio2 wuxuu leeyahay qaab seddex-geesood ah oo shabakadda ah, oo leh tiro badan oo ah kooxo firfircoon oo ku jirta dusha sare ee ku yaal dusha sare. Waxay hagaajin kartaa guryaha dhameystiran ee ka dib markii lagu daray polyurethane by polyurethane by bov iyo godyada van den de van den der. ISTIASESESED NANO-SIO2 MORENED POLYURETANE ISTICMAALKA HESHIISKA DIIWAANKA EE SANDING. Marka ay ka kooban tahay SIO2 waxay ahayd qiyaastii 2% (WT, jajab ballaaran, oo isku mid ah), aragtida xiirashada iyo xoogga dheriga ee aasaasiga ah ayaa loo hagaajiyay. Marka la barbar dhigo polyanurethane saafi ah, iska caabinta heerkulka sare iyo xoogga khasabka ah ayaa sidoo kale xoogaa kordhay.
Nano zinc
Nano zno waxay leedahay awood farsamo oo sareysa, oo si fiican u bakteeriyada bakteeriyada iyo ka hortaga ah, iyo sidoo kale awood xoog leh oo lagu soo nuugo shucaaca sifiican loo yaqaan 'Shoct' oo wanaagsan, taasoo ka dhigeysa inay ku habboon tahay samaynta agabyada qaaska ah. Awad et al. Waxaa loo adeegsaday habka 'Positron-ka' Moitron-ka oo lagu daro zono zlo zoorethane. Daraasaddu waxay ogaatay inay jirto is-dhexgal dhex-dhexaad ah oo ka dhexeeya nanoparticles iyo polyurethane. Kordhinta waxa ku jira Nano zno ee 0 illaa 5% waxay kordhiyeen heerkulka kala-guurka quraaradda (TG) ee Polyanurethane, oo wanaajisay xasilloonida kuleylka.
Nano kaalshiyamka nano kaboon
Is dhexgalka xoogan ee u dhexeeya Nano Caco3 iyo matrix ayaa si weyn u kobcinaya xoogga khasabka ah ee agabka polyurethane. Gao et al. Markii ugu horreysay ee wax laga beddelay Nano-Caco3 oo leh oleic acid, ka dibna loo diyaariyey polyurethane / Caco3 iyada oo loo marayo plmber-ka-dhisidda-dhisida. Tijaabada infakshanka (FT-IR) ayaa muujisay in nanoparticles-ka ay si isku mid ah ugu kala firidhsan yihiin matrix. Marka loo eego baaritaanada waxqabadka farsamada, waxaa la ogaaday in Polyurethane wax laga beddelay nanoparticles-ka uu leeyahay awood aad u sarreysa marka loo eego polyurethane saafi ah.
Farafti
Garaaf (g) waa qaab dhismeedka layaabka leh oo uu ku xidhan yahay orbitals-ka 'sp2', kaas oo muujinaya wanaagga wanaagsan, oo muujinaya wanaajinta wanaagsan, wanaajinta kuleylka, iyo xasilloonida. Waxay leedahay xoog sare, adag, waana fududahay in la laabo. Wu et al. AG / G / PU Nanocomposites AG / G / PU Nanocomposites, iyo kororka waxyaabaha ku jira AG / G, xasilloonida kuleylka iyo hydrophobicitity ee sheyga iswaafaqsan ayaa sii waday hagaajinta, iyo waxqabadka bakteeriyada ka hortaga bakteeriyada ayaa sidoo kale kordhay.
Karbon nanotubes
Kaarboon Nutoubes (CNTS) waa unugyo-cabbir-cabbir hoosaadyo ah oo ku xidhan Hexalons, oo hadda waa mid ka mid ah agabyada leh codsiyo fara badan. Adigoo adeegsanaya xooggeeda sare, wajahda, iyo polyurethaneether-ka, xasilloonida kuleylka, guryaha farsamada, iyo wada-shaqeynta maaddada ayaa la wanaajin karaa. Wu et al. Waxaa lagu soo bandhigay CNTS iyada oo loo marayo gudaha-ku-meel-gaarka ah si loo xakameeyo koritaanka iyo abuurista walxaha emulsion, taasoo u oggolaaneysa in CNTs si isku mid ah loogu kala firdhiyo matrix-ka polyurethane matrix. Iyada oo la sii kordhayo waxa ku jira CNTs, xoogga khasabka ah ee sheyga isku-dhafka ah si weyn ayaa loo hagaajiyay.
Shirkaddayadu waxay siisaa silica tayo sare leh oo tayo sare leh,Wakiilka ka hortagga hydrolysis (wakiilada iskutallaabta, carbodimimimide), UV wuxuu maqnaa, iwm., oo si weyn u hagaajiya waxqabadka polyanurethane.
