Gulu ndi kuyambitsa koyambira kwa utomoni wa UV

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

UV utomoni ndi photosensitive utomoni ndi otsika wachibale utomoni.Lili ndi magulu ochitapo kanthu omwe amatha kuchita UV, monga ma bond awiri osakhazikika kapena magulu a epoxy

Utoto wa UV ndi utomoni wa matrix wa zokutira za UV.Zimaphatikizidwa ndi photoinitiator, diluent yogwira ntchito ndi zowonjezera zosiyanasiyana kuti apange zokutira za UV

Uvpaint ili ndi zabwino izi:

(1) Kuthamanga kwachangu komanso kuchita bwino kwambiri;

(2) Kugwiritsa ntchito mphamvu kwambiri komanso kusunga mphamvu;

(3) Zochepa za organic volatile matter (VOC) komanso zachilengedwe;

(4) Itha kukhala yokutidwa ndi magawo osiyanasiyana, monga pepala, pulasitiki, zikopa, zitsulo, galasi, zoumba, etc;

Utoto wa UV ndiye gawo lomwe lili ndi gawo lalikulu kwambiri pazopaka za UV komanso utomoni wa matrix mu zokutira za UV.Nthawi zambiri imakhala ndi magulu omwe amatha kuchitapo kanthu kapena kupanga polymerize pansi pamikhalidwe yopepuka, monga carbon carbon double bond, epoxy group, etc. Malinga ndi mitundu yosiyanasiyana ya zosungunulira, utomoni wa UV ukhoza kugawidwa muzosungunulira zochokera ku UV ndi utomoni wamadzi wa UV Zosungunulira zochokera kulibe magulu hydrophilic ndipo akhoza kusungunuka mu zosungunulira organic, pamene utomoni amadzimadzi muli magulu hydrophilic kapena zigawo hydrophilic unyolo, amene akhoza emulsified, omwazika kapena kusungunuka m'madzi.

Magulu a UV resins:

Zosungunulira zochokera ku UV utomoni

Mafuta osungunulira omwe amagwiritsidwa ntchito kwambiri a UV 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 silikoni oligomer

Amadzimadzi UV utomoni

Utoto wamadzi wamadzi wa UV umatanthawuza utomoni wa UV womwe umasungunuka m'madzi kapena kumwazikana ndi madzi.The molekyulu lili osati chiwerengero cha magulu amphamvu hydrophilic, monga carboxyl, hydroxyl, amino, etha, acylamino, etc., komanso magulu unsaturated, monga acryloyl, methacryloyl kapena allyl Waterborne UV mitengo akhoza kugawidwa mu mitundu itatu: mafuta odzola, kumwazikana kwamadzi ndi kusungunuka kwamadzi Zimaphatikizapo magulu atatu: polyurethane acrylate yamadzi, epoxy acrylate yamadzi ndi polyester acrylate

Magawo akuluakulu ogwiritsira ntchito utomoni wa UV: utoto wa UV, inki ya UV, guluu la UV, ndi zina zambiri, zomwe utoto wa UV ndi womwe umagwiritsidwa ntchito kwambiri, kuphatikiza mitundu yotsatirayi ya utoto wotengera madzi a UV, utoto wa ufa wa UV, utoto wachikopa wa UV, UV. utoto wonyezimira, utoto wachitsulo wa UV, utoto wonyezimira wa pepala wa UV, utoto wa pulasitiki wa UV, utoto wamatabwa wa UV.
