2024-05-13
Ma inki osindikizira a UV ndi zida zosindikizira zapadera zomwe zimapangidwira kuchiritsa mwachangu kwa ultraviolet (UV). Mapangidwe ake amapangidwa mwaluso kwambiri kuti atsimikizire kusindikiza kwapamwamba komanso zowumitsa nthawi yomweyo. Zigawo zoyambira za inkizi zitha kufotokozedwa motere:
- Ma resins Ochilitsidwa ndi UV: Pamtima pa inkiyi pali ma resin omwe amakhudzidwa ndi UV, monga ma acrylates, ethylene esters, ndi epoxy resins, omwe amalumikizana mwachangu ndikuchiritsa ndi cheza cha UV.
- Ma Monomers: Ogwiritsidwa ntchito molumikizana ndi utomoni wochiritsika ndi UV, ma monomers monga acrylic ndi methacrylic acid esters amathandizira njira zama polymerization zikayatsidwa ndi kuwala kwa UV, kufulumizitsa kuchiritsa.
- Photoinitiators: Zinthuzi zimatenga mphamvu za UV ndikuzisintha kukhala mphamvu zama mankhwala, zomwe zimayambitsa ma polymerization mkati mwa inki. Amakhala ndi oyambitsa ndi othandizira othandizira.
- Mitundu ya Pigment ndi Pigment Dispersants: Inki imapereka mtundu komanso mawonekedwe, pomwe zotulutsa zimatsimikizira ngakhale kubalalitsidwa kwa mitundu kuti ikhale yamitundu yosiyanasiyana komanso kusindikizidwa bwino.
- Zowonjezera: Kuphatikiza ma antioxidants, UV stabilizers, rheology modifiers, harderner, pakati pa ena, awa akuphatikizidwa kuti apititse patsogolo ntchito ya inki ndi bata. Diluents amagwiritsidwanso ntchito kusintha mamasukidwe akayendedwe ndi kuyenda, kuthandiza zosiyanasiyana kusindikiza zofunika.
- Zowonjezera: Kutengera wopanga ndi zomwe mukufuna kugwiritsa ntchito, inki zitha kuphatikizira zinthu zina monga zotulutsa ndi anti-setting agents. Zolemba zimasinthidwa kuti zigwirizane ndi zofunikira zinazake.
Mwachidule, ma inki osindikizira a UV, omwe amachiritsa mwachangu, kukana abrasion, kulimba kwa mankhwala, komanso mtundu wapadera wa kusindikiza, amapeza ntchito zambiri pantchito yosindikiza, makamaka pantchito zosindikiza zapamwamba komanso zapamwamba kwambiri.
