Chiyambi Chachikulu cha UV Resin

Utoto wa UV, womwe umadziwikanso kuti photosensitive resin, ndi oligomer yomwe imatha kusintha mwachangu thupi ndi mankhwala pakangopita nthawi yochepa itatha kuwala, potero imalumikizana ndikuchiritsa.

UV utomoni ndi photosensitive utomoni ndi ochepa molekyulu kulemera, ndipo ali magulu reactive kuti angathe kuchita UV, monga unsaturated double bond kapena epoxy magulu.

Utoto wa UV ndiye utomoni woyambira wa zokutira za UV, zomwe zimaphatikizidwa ndi ma photoinitiators, zosungunulira zogwira ntchito, ndi zowonjezera zosiyanasiyana kuti apange zokutira za UV.

Zovala za UV zili ndi zabwino izi:

(1) Kuthamanga kwachangu komanso kuchita bwino kwambiri;

(2) Kugwiritsa ntchito mphamvu kwambiri komanso kupulumutsa mphamvu;

(3) Low organic volatile matter (VOC), wokonda zachilengedwe;

(4) Akhoza TACHIMATA ndi magawo osiyanasiyana, monga pepala, pulasitiki, zikopa, zitsulo, galasi, zoumba, ndi zina zotero;

Utoto wa UV ndiye gawo lalikulu kwambiri pazopaka za UV, ndipo ndiye utomoni woyambira pazopaka za UV.Nthawi zambiri imakhala ndi magulu omwe amatha kuchitapo kanthu kapena ku polymerize pansi pamikhalidwe yowala, monga zomangira za kaboni wapawiri, magulu a epoxy, etc. Malinga ndi mtundu wa zosungunulira, ma resins a UV amatha kugawidwa m'magulu awiri: zosungunulira zochokera ku UV ndi utomoni wamadzi wa UV. .Zosungunulira zochokera ku utomoni zilibe magulu a hydrophilic ndipo zimatha kusungunuka mu zosungunulira za organic, pomwe utomoni wamadzi uli ndi magulu kapena magawo ambiri a hydrophilic, omwe amatha kupangidwa m'madzi, Kubalalika kapena kusungunuka.

Magulu a UV resins:

Zosungunulira zochokera ku UV utomoni

Zosungunulira zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi: UV unsaturated polyester, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV pure acrylic resin, UV epoxy resin, ndi UV organosilicon oligomers.

Utoto wamadzi wa UV

Ma resins a UV omwe amapezeka m'madzi amatanthauza ma resin a UV omwe amasungunuka m'madzi kapena amatha kumwazikana m'madzi.Mamolekyuwa ali ndi magulu ena amphamvu a hydrophilic, monga carboxyl, hydroxyl, amino, ether, acylamino, ndi zina zotero, komanso magulu a unsaturated, monga acryloyl, methacryloyl, kapena allyl.Mitengo ya UV yomwe imakhala ndi madzi imatha kugawidwa m'magulu atatu: mafuta odzola, otayika madzi, ndi osungunuka m'madzi.Iwo makamaka amaphatikizapo magulu atatu: waterborne polyurethane acrylate, waterborne epoxy acrylate, ndi waterborne polyester acrylate.

Minda yayikulu yogwiritsira ntchito utomoni wa UV: zokutira za UV, inki za UV, zomatira za UV, ndi zina zambiri. Pakati pawo, zokutira za UV ndizomwe zimagwiritsidwa ntchito kwambiri, kuphatikiza mitundu iyi ya zokutira zotengera madzi a UV, zokutira za ufa wa UV, zokutira zachikopa za UV, UV. zokutira za ulusi wa kuwala, zokutira zachitsulo za UV, zokutira zokutira za pepala za UV, zokutira zapulasitiki za UV, zokutira zamatabwa za UV.
