Madzi am'madzi polyirethane ndi mtundu watsopano wa dongosolo la polyirethane lomwe limagwiritsa ntchito madzi m'malo mwa organic solters ngati obalalitsa sing'anga. Ili ndi zodetsa nkhawa, chitetezo ndi kudalirika, katundu wabwino kwambiri, kuyerekezera bwino, komanso kusintha kosavuta.
Komabe, zida za polyirethaic zimadwalanso chifukwa cha kukana madzi osanja, kukana kwa kutentha, komanso kukana kusinthika chifukwa cha kusowa kwa zomangira zolumikizirana.
Therefore, it is necessary to improve and optimize the various application properties of polyurethane by introducing functional monomers such as organic fluorosilicone, epoxy resin, acrylic ester, and nanomaterials.
Mwa iwo, zinthu za Nanomatadi zosinthika zimatha kukonza kwambiri mphamvu zawo, kuvala, komanso kukhazikika kwa mafuta. Njira zosinthira zimaphatikizapo njira yophatikizira yophatikizira, njira ya polymerization polymerization, njira yophatikizira, etc.
Nano silica
Sio2 ali ndi mawonekedwe a ma netiweki atatu, okhala ndi magulu ambiri a hydroxyl pamwamba. Itha kukonza zinthuzo zikaphatikizidwa ndi polyurethane ndi mgwirizano wolumikizana ndi van der alfir, monga kusinthasintha kutentha, kukana kutentha, etc. guo et al. Matenda a nano-sio2 osinthidwa polyirethane pogwiritsa ntchito njira ya polymerization. Pamene zikhalidwe za Sio2 zakwana 2% (wt, kachigawo kakang'ono, zomwezo pansipa), kuwoneka kowoneka bwino komanso kuwononga mphamvu ya motsatiradi. Poyerekeza ndi polsurethane, kutentha kwambiri kumatsutsana ndi kuwoneka kuti mphamvu yachulukitsidwe pang'ono.
Nano zinc oxide
Nano Zno ali ndi mphamvu zapamwamba, antibacterial ndi bacteriostatic katundu, komanso kukhoza kwamphamvu kuti atengere radiation ndi uV yabwino yoteteza zinthu, ndikupanga zida zapadera. Awad et al. Gwiritsani ntchito njira ya nano pos pospon kuphatikizira Zno ojambula mu polyurethane. Kafukufukuyu adawona kuti panali kulumikizana kwa Nanoparticles ndi pourerethane. Kuchulukitsa zomwe zachitika ku Nano Zno kuchokera ku 0 mpaka 5% kuwonjezeka kutentha kwagalasi (TG) ya polyirethane, yomwe idasintha bata.
Nano calcium carbonate
Kulumikizana kwamphamvu pakati pa nano COCO3 ndi matrix kumapangitsa kwambiri mphamvu yakuwoneka kwa zida za polyuretha. Gao et al. Choyamba kusinthidwa ndi CACO3 ndi Oleic acid, kenako adakonza polyurethane / Caco3 kudzera-suti polymerization. Kuyesa kwaulere (FT-IR) kunawonetsa kuti nanoparticles anali ofanana obalalitsidwa mu matrix. Malinga ndi mayeso ogwiritsira ntchito makina, zinapezeka kuti poureorethane adasinthidwa ndi nanoparticles ali ndi mphamvu kwambiri kuposa polyurethane.
Gitala
Graphene (g) ndi kapangidwe kambiri ndi SP2 wosakanizidwa mablebils, omwe amaonetsa mawonekedwe abwino, mawonekedwe a matenthedwe, komanso bata. Ili ndi mphamvu zambiri, kulimba mtima, ndipo ndikosavuta kugwada. Wu et al. Matenda a AG / G / Pu Nanocomposites, ndipo ndi kuchuluka kwa ag / g okhazikika, kukhazikika kwa matenthedwe, ndipo ma hydrophobicity a zinthu zophatikizikazo adapitiliranso.
Kaboni nanotubes
Carbon nanotubes (Cnts) ndi ma a tubular a tubular olumikizidwa ndi ma hexagons, ndipo pakali pano pali chimodzi mwazinthu zomwe zili ndi mapulogalamu osiyanasiyana. Pogwiritsa ntchito mphamvu zake zazikulu, zamakhalidwe, ndi polyirethane zimaphatikizika, kukhazikika kwamatenthedwe, makina, komanso mawonekedwe a zinthuzi zitha kusintha. Wu et al. Anayambitsa Cnts kudzera mu-suti ya polymerization kuti muchepetse kukula ndi mapangidwe a emulsion tinthu tating'onoting'ono, zomwe zimapangitsa kuti ziwonekere kukhala zobalalika mwamphamvu mu polyurethane matrix. Ndi zochulukirambiri za Cnts, kulimba kwa matenda a zinthu zophatikizika kwakhala kukuthandizani kwambiri.
Kampani yathu imapereka silika wapamwamba kwambiri,Anti-Hydrolysis (othandizira, Carbodiimide), Mafuta a UV, etc., yomwe imasinthiratu magwiridwe antchito a polyirethane.
