Waterborne polyurethane rudzi rutsva rwePolyurethane system inoshandisa mvura pane organic sol sol sol solium. Iyo ine zvakanakira kusvibiswa, kuchengeteka uye kuvimbika, kwakanakisa manhamba, kukanganisika, uye nyore kugadziridzwa.
Nekudaro, zvigadzirwa zvePolenurethane zvakare zvinotambura zvakare kupokana nemvura, kupesana nekupisa, uye solvent kuramba nekuda kwekushaikwa kwekubatanidza kuunganidza boka rekubatanidza.
Naizvozvo, zvinodikanwa kuti uvandudze uye gadzirisa zvinhu zvakasiyana-siyana zvePolyurethane nekuunza masimba masoja sollorosirilone, epoxy resin, acrylic ester, uye nanomatari.
Pakati pavo, Nanomerialialialialidified touredhane midziyo inogona kuvandudza zvakanyanya zvivakwa zvavo zvekuchinja, kupfeka kurwisa, uye kugadzikana kwekunyora. Nzira dzekuchemedzeka dzinosanganisira nzira yekuvhiringidza nzira, mu-muto Polymerization nzira, kusanganisa nzira, nezvimwe.
Nano Silica
Sio2 ine matatu-dimensional network network, ine nhamba yakakura yeiyo inoshanda hydroxyl mapoka pamusoro payo. Zvinogona kuvandudza zvinhu zvakazara zveyakajaira mushure mekubatanidzwa nePolyurethane necalalent Bond uye vanenge vachishandura, zvakakwirira zvekupesana, etcing kupokana, etc. guo et al. synthesized nano-sio2 yakagadziridzwa polyurethane uchishandisa In-Sit Polymerization nzira. Kana iyo Sio2 yezvinyorwa yaive anenge 2% (WT, misa chidimbu, icho chimwe chete pazasi), iyo shear viscosity uye simba reEel yeAnhesive yakagadziridzwa zvakanyanya. Kuenzaniswa neakachena polyurethane, iyo yakanyanya kupisa kudzikisira uye simba rakafanana zvakare rakawedzera zvishoma.
NANO Zinc oxide
NARE Zno ine yakakwira mechaniki simba, yakanaka antibacterial simba uye nebhavhu zvine simba, pamwe nekusimba kwakasimba kwekutora radiation uye yakanaka uv yekuvhara, ichiita kuti ive yakakodzera kugadzira zvinhu zvine mabasa akakosha. Awad et al. akashandisa nano positron nzira yekubatanidza zno mafiriyoni muPolyurethane. Chidzidzo ichocho chakawana kuti pakanga paine musangano wekudyidzana pakati peNaoparticles uye polyurethane. Kuwedzera zvirimo muNano zno kubva ku0 kusvika ku5% yakawedzera tembiricha yekudziya (tg) yePolyurethane, iyo yakavandudza kugadzikana kwayo.
Nano calcium carbonate
Kubatanidzwa kwakasimba pakati pano caccount3 uye matrix zvakanyanya kuisimudzira sosi yePolyurethane. Gao et al. Chekutanga Modified Nano-Caco3 ne Oleic Acid, uye wobva wagadzirira Polyurethene / Cacco3 kuburikidza neIn-Sun Polmerization. Infrared (ft-IR) kuongororwa yakaratidza kuti nanhararticles yaive yakapararira yakafanana mune matrix. Sekureva kwemitambo yekuita zvekuita, yakawanikwa kuti polyurethane yakashandurwa neNanoparticles ine yakakwira simba pane yakachena polyurethane.
Grapheene
Grapheene (g) chimiro chakarongedzwa chakasungwa neSp2 Hybrid orbbitals, izvo zvinoratidzira zvakanyanya kuitwa, zvinoparara, uye kugadzikana. Iyo ine simba rakanyanya, hukasha, uye riri nyore kukotama. Wu et al. Synthesizized AG / G / Pu NuanoComposites, uye nekuwedzera kweAG / G.Comeni, kugadzikana kweiyo, kugadzikana kwehymal uye hydrophos
Kabhoni nanotubes
Carbon Nanotubes (CENTE) Ndege imwe chete yeTubular Nanomartials yakabatana neHexagons, uye ikozvino iri yezvinhu zvine huwandu hwakawanda hwekushandisa. Nekushandisa simba rayo rakakwirira kwazvo, kubatana, uye polyurethane composite zvivakwa, kugadzikana kwekunyora, zvimiro zvemichina, uye kuita zvinyorwa zvinogona kuvandudzwa. Wu et al. Yakatangwa CENT kuburikidza nePolymerization kudzora kukura uye kuumbwa kwemitsetse, inogonesa matanda kuti ive yakagadzikana muPolyurethane matrix. Nezvemukati mekuwedzera kwemapango, simba rakafanana rezvinyorwa zvemukati rakavandudzwa zvikuru.
Kambani yedu inopa yakakwirira-mhando yemhando yeSilica,Anti-Hydrolysis vamiririri (Crosslinking vamiririri, Carbodiimide), UV inobata, etc., iyo inovandudza zvakanyanya kuita kwePolyurethane.
