Product Description
ZC6523 yog ib qho trifunctional polyurethane acrylate synthesized los ntawm polymerization ntawm polyester polyol, aromatic isocyanate curing agent thiab hydroxyethyl acrylate, los yog photosensitive curing resin.Nws cov kev Performance index: viscosity yog 5000-6000mpa S / 25 ℃, acid tus nqi <0.5 (NCO%), functionality 3 (tus nqi theoretical), xim tooj: 1# (Gardner);Cov khoom no muaj qhov zoo ntawm kev ua haujlwm zoo, hnav tsis kam, khawb tsis kam, kub tsis kam, dej tsis kam, siab tiv thaiv kev ua haujlwm thiab lwm yam.Nws yog dav siv nyob rau hauv lub lag luam ntawm lub teeb curing number case, ntoo rooj tog, pem teb txheej, ntawv txheej, yas txheej, optical fiber txheej, hlau txheej thiab nplaum.
UV resin xav tau lub teeb curing txheej ua los ntawm kev ntxiv cov tshuaj nquag, photoinitiator, additives, pigments thiab fillers, thiab ib hom tshiab ntawm txheej txheej tuaj yeem tsim los ntawm UV irradiation ntxiv.Nws cov txheej txheem txheej muaj xws li cov menyuam txheej, cov txheej txheem drenching, txau, drip txheej thiab lwm yam txheej txheem.Qhov zoo ntawm cov txheej no yog kev tiv thaiv ib puag ncig, kev tsim kho sai (Ceeb toom: nws tsis txwv los ntawm huab cua, kub thiab av noo), thiab kev txuag hluav taws xob, cov khoom tsim muaj kev ua tau zoo thiab lwm yam.
Lub molecule ntawm polyurethane acrylate (PUA) muaj acrylic functional pawg thiab carbamate bonds.Cov nplaum kho tau zoo hnav tsis kam, adhesion, yooj, siab tawv lub zog, zoo heev kub tsis kam ntawm polyurethane thiab cov khoom siv kho qhov muag zoo heev thiab huab cua tsis kam ntawm polyacrylate.Nws yog cov khoom siv hluav taws xob kho nrog cov khoom zoo heev.PUA tau dhau los ua cov chav kawm tseem ceeb ntawm oligomers hauv thaj chaw ntawm cov txheej txheem dej tsis zoo.Vim muaj kev ua tau zoo ntawm PUA resin, kev tshawb fawb ntawm PUA kuj nce ntxiv.Polyurethane acrylate kuj maj mam copolymerized nrog lwm hom resins los tsim hybrid system thiab tsim rau hauv aqueous system.Hauv tshwj xeeb, lub tshuab aqueous ncaj qha siv dej los dilute thiab txo cov viscosity, uas ua rau cov coatings ntau tus phooj ywg ib puag ncig thiab noj qab haus huv thiab txo cov kev siv cov monomers nquag, kom ntau npaum li cas, nws ua rau tsis muaj nqi ntawm PUA resin. , uas tuaj yeem nthuav dav daim ntawv thov ntau yam ntawm PUA resin, txo lossis txawm tias tsis siv cov monomers, txo qhov shrinkage ntawm waterproof txheej, txo cov kev ntxhov siab sab hauv thaum kho, ua kom cov adhesion ntawm txheej thiab txhim kho qhov yooj yim ntawm txheej zaj duab xis.
