Polyurethane yoyendetsedwa ndi madzi ndi mtundu watsopano wa makina a polyurethane omwe amagwiritsa ntchito madzi m'malo mwa zinthu zachilengedwe zosungunulira ngati njira yofalitsira. Uli ndi ubwino wosakhala ndi kuipitsa, chitetezo ndi kudalirika, uli ndi mphamvu zabwino kwambiri pamakina, umagwirizana bwino, komanso umasinthasintha mosavuta.
Komabe, zinthu zopangidwa ndi polyurethane zimakhalanso ndi vuto losalimba la madzi, kukana kutentha, komanso kukana zosungunulira chifukwa cha kusowa kwa ma bond okhazikika olumikizirana.

Chifukwa chake, ndikofunikira kukonza ndikukonza magwiridwe antchito osiyanasiyana a polyurethane poyambitsa ma monomers ogwira ntchito monga organic fluorosilicone, epoxy resin, acrylic ester, ndi nanomaterials.
Pakati pa izi, zipangizo za polyurethane zosinthidwa ndi nanomaterial zimatha kusintha kwambiri mawonekedwe awo a makina, kukana kuwonongeka, komanso kukhazikika kwa kutentha. Njira zosinthira zimaphatikizapo njira yophatikizira pakati, njira ya polymerization ya mkati, njira yosakaniza, ndi zina zotero.

Nano Silika
SiO2 ili ndi kapangidwe ka netiweki ka magawo atatu, yokhala ndi magulu ambiri a hydroxyl omwe amagwira ntchito pamwamba pake. Imatha kukonza mawonekedwe athunthu a composite pambuyo pophatikizidwa ndi polyurethane ndi covalent bond ndi van der Waals force, monga kusinthasintha, kukana kutentha kwambiri komanso kotsika, kukana ukalamba, ndi zina zotero. Guo et al. adapanga nano-SiO2 modified polyurethane pogwiritsa ntchito njira ya in-situ polymerization. Pamene kuchuluka kwa SiO2 kunali pafupifupi 2% (wt, mass fraction, yomweyi pansipa), kukhuthala kwa shear ndi peel kwa guluu kunakula kwambiri. Poyerekeza ndi polyurethane yoyera, kukana kutentha kwambiri komanso mphamvu yokoka nazonso zawonjezeka pang'ono.

Nano Zinc Okusayidi
Nano ZnO ili ndi mphamvu zambiri zamakaniko, imateteza mabakiteriya komanso mabakiteriya, komanso imatha kuyamwa kuwala kwa infrared komanso kuteteza bwino UV, zomwe zimapangitsa kuti ikhale yoyenera kupanga zinthu zomwe zili ndi ntchito zapadera. Awad et al. adagwiritsa ntchito njira ya nanopositron kuti agwiritse ntchito ZnO fillers mu polyurethane. Kafukufukuyu adapeza kuti panali kulumikizana pakati pa nanoparticles ndi polyurethane. Kuwonjezeka kwa nano ZnO kuchokera pa 0 mpaka 5% kunawonjezera kutentha kwa galasi (Tg) ya polyurethane, zomwe zinapangitsa kuti kutentha kwake kukhale kolimba.

Nano Calcium Carbonate
Kugwirizana kwamphamvu pakati pa nano CaCO3 ndi matrix kumawonjezera kwambiri mphamvu yokoka ya zinthu za polyurethane. Gao ndi anzake adasintha koyamba nano-CaCO3 ndi oleic acid, kenako adakonza polyurethane/CaCO3 kudzera mu polymerization ya mkati. Kuyesa kwa infrared (FT-IR) kunawonetsa kuti nanoparticles zidafalikira mofanana mu matrix. Malinga ndi mayeso a magwiridwe antchito a makina, zidapezeka kuti polyurethane yosinthidwa ndi nanoparticles ili ndi mphamvu yokoka kwambiri kuposa polyurethane yoyera.

Graphene
Graphene (G) ndi kapangidwe ka zigawo zolumikizidwa ndi ma orbitals a SP2 hybrid, omwe amasonyeza kuyendetsa bwino kwambiri, kuyendetsa bwino kutentha, komanso kukhazikika. Ili ndi mphamvu zambiri, kulimba bwino, ndipo ndi yosavuta kupindika. Wu et al. adapanga ma nanocomposites a Ag/G/PU, ndipo chifukwa cha kuchuluka kwa Ag/G, kukhazikika kwa kutentha ndi kusagwirizana ndi madzi kwa zinthu zophatikizika kunapitirirabe kukula, ndipo mphamvu ya antibacterial inakulanso moyenerera.

Machubu a Nanocarbon
Ma nanotubes a kaboni (CNTs) ndi zinthu zopangidwa ndi ma tubular okhala ndi mbali imodzi zomwe zimalumikizidwa ndi ma hexagon, ndipo pakadali pano ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito mosiyanasiyana. Pogwiritsa ntchito mphamvu zake zapamwamba, mphamvu zoyendetsera, komanso mphamvu zophatikizana za polyurethane, kukhazikika kwa kutentha, mphamvu zamakina, ndi mphamvu zoyendetsera zinthuzo zitha kukonzedwa. Wu et al. adayambitsa ma CNT kudzera mu polymerization ya mkati kuti alamulire kukula ndi kapangidwe ka tinthu ta emulsion, zomwe zimathandiza kuti ma CNT azifalikira mofanana mu polyurethane matrix. Ndi kuchuluka kwa ma CNT, mphamvu yolimba ya zinthu zopangidwa ndi zinthuzo yakula kwambiri.

Kampani yathu imapereka zinthu zabwino kwambiriFumed Silica, Mankhwala Oletsa Kupha Madzi (mankhwala olumikizirana, Carbodiimide), zoyamwa UV, ndi zina zotero, zomwe zimathandizira kwambiri magwiridwe antchito a polyurethane.
