Gulu Losavuta la UV Resins

Utoto wa UV, womwe umadziwika kuti photosensitive resin, ndi oligomer yomwe imatha kusintha kusintha kwa thupi ndi mankhwala pakangopita nthawi yochepa itatha kuyatsa, kenako ndikudutsana ndikukhazikika.Utoto wa UV umagawika makamaka kukhala zosungunulira zochokera ku UV utomoni ndi utomoni wamadzi wa UV.

Zosungunulira zochokera ku UV utomoni

Mafuta osungunulira opangidwa ndi UV wamba makamaka akuphatikizapo: UV unsaturated polyester, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV pure acrylic resin, UV epoxy resin, UV silicone oligomer, etc.

Madzi a UV utomoni

Utoto wa UV wa m'madzi umatanthawuza utomoni wa UV womwe umasungunuka m'madzi kapena kumwazikana ndi madzi.Molekyu ili ndi magulu angapo amphamvu a hydrophilic, monga carboxyl, hydroxyl, amino, ether, ndi magulu acylamine;Mulinso magulu osatutulidwa, monga acryloyl, methacryloyl kapena magulu a allyl.Mitengo ya UV yomwe imakhala ndi madzi imatha kugawidwa m'magulu atatu: mafuta odzola, otayira madzi komanso osungunuka m'madzi, makamaka kuphatikizapo magulu atatu: waterborne polyurethane acrylate, waterborne epoxy acrylate ndi waterborne polyester acrylate.

Utoto wopangidwa ndi madzi wa UV nthawi zambiri umakhala ndi 80-90% yopangidwa ndi madzi ndi 10-20% zowonjezera zina.Pambuyo kupaka ndi kupukuta, wosanjikiza woonda wopangidwa ndi polima amasiyidwa pamwamba pa gawo lapansi, lomwe limapangitsa kuti zokutirako zikhale ndi mawonekedwe osiyanasiyana chifukwa chamitundu yosiyanasiyana.Monga high gloss, matt, abrasion resistant, etc.

Utoto wa m'madzi ndiye chigawo chachikulu cha Z mu utomoni wa UV wa m'madzi.Zimatsimikizira ndi kukhudza katundu wa madzi UV utomoni, monga luster, adhesion, abrasion kukana, dryness, etc. Choncho, kusankha bwino madzi UV utomoni ndi chinsinsi kuti bwino kutumizidwa madzi utomoni UV.

Pali mitundu yambiri ya utomoni, kuphatikizapo rosin wopangidwa ndi madzi osinthidwa maleic resin, waterborne polyurethane resin, waterborne acrylic resin, waterborne alkyd resin, waterborne amino resin, etc. kutulutsidwa kwa madzi, gloss yabwino pambuyo pa kupanga filimu, kukana kutentha, kukana kwa mankhwala, kufulumira kuyanika mofulumira, ndi zina zotero, pamene madzi a acrylic copolymer resin amatha kukwaniritsa zofunikira za kusindikiza ndi glazing kwambiri.Chifukwa chake, pokonzekera utomoni wa UV wamadzi, makina opangidwa ndi acrylic copolymer amakhala chisankho chathu chabwino.

Aqueous acrylic copolymer resin amatha kugawidwa mumadzimadzi a acrylic resin solution, amadzimadzi a acrylic dispersion, ndi acrylic odzola.Mafuta odzola a Acrylic amatha kugawidwa kukhala odzola opangidwa ndi acrylic ndi osapanga filimu odzola.Makhalidwe a madzi a acrylic copolymer resin amapangidwa ndi ma monomers.Magwiridwe ndi kaphatikizidwe ndondomeko.Ma monomers ena amatha kusintha kuwala ndi kuuma, pomwe ena amatha kukana mankhwala komanso kumamatira.Zoyeserera zambiri zatsimikizira kuti utomoni wamadzi wa UV, womwe umaphatikizidwa mwasayansi ndi aqueous acrylic acid solution ndi acrylic acid lotion, uli ndi zinthu zabwino.
