Makhalidwe ndi kugwiritsa ntchito mitundu yosiyanasiyana ya ma resin ochiritsira a UV

UV Curring (UV) utomoni ndi mtundu wa utomoni wa photosensitive wokhala ndi mamolekyu ochepa olemera.Lili ndi magulu omwe amatha kuchita machiritso a UV, monga ma bond awiri osagwirizana kapena magulu a epoxy.Ndilo gawo lalikulu la zinthu zochizira UV (zophimba za UV, inki ya UV, zomatira za UV, ndi zina zambiri), ndipo magwiridwe ake amatsimikizira magwiridwe antchito azinthu zochiritsidwa.

Pakadali pano, utomoni wapakhomo wa UV wochiritsika makamaka umaphatikizapo epoxy acrylate, polyurethane acrylic resin, polyester acrylic resin, amino acrylic resin ndi chithunzi cha alkali soluble resin.

Makhalidwe ndi kugwiritsa ntchito mitundu yosiyanasiyana ya ma resin ochiritsira a UV

1. Epoxy acrylic resin ndiye amagwiritsidwa ntchito kwambiri komanso kuchuluka kwakukulu kwa utomoni wochiritsa wa UV pakadali pano.Chifukwa chosavuta kaphatikizidwe, gwero losavuta la zopangira, mtengo wotsika, kuthamanga kwachangu kuchiritsa, kuuma kwakukulu, gloss, kukana kwambiri kwamankhwala, kukana kutentha komanso mphamvu zamagetsi, epoxy acrylic resin imagwiritsidwa ntchito kwambiri ngati utomoni waukulu wa kuwala. mapepala ochiritsidwa, matabwa, pulasitiki ndi zokutira zachitsulo, inki yochiritsidwa yopepuka komanso zomatira zopepuka.Mitundu yayikulu ndi bisphenol A epoxy acrylic resin, phenolic epoxy acrylic resin, epoxy oil acrylate ndi zosiyanasiyana zosinthidwa epoxy acrylic resin.

2. Polyurethane acrylic resin imagwiritsidwanso ntchito kwambiri, utomoni wambiri wochiritsa kuwala.Polyurethane acrylic resin imagwiritsidwa ntchito kwambiri pamapepala ochiritsira a UV, matabwa, pulasitiki ndi zitsulo zokutira, inki zochiritsira za UV ndi zomatira zochiritsira za UV chifukwa champhamvu zake zonse, monga kukana kwabwino kwambiri komanso kusinthasintha, kukana bwino kwamankhwala, kukana kwamphamvu komanso mphamvu zamagetsi. filimu yochiritsidwa, ndikumatira bwino kwa mapulasitiki ndi magawo ena.Mitundu yayikulu ndi onunkhira komanso aliphatic polyurethane acrylic resin.

3. Polyester acrylic resin ndiwogwiritsidwanso ntchito kwambiri pochiritsa utomoni.Chifukwa utomoniwo umakhala ndi fungo lochepa, kupsa mtima pang'ono, kusinthasintha bwino komanso kunyowa kwa pigment, nthawi zambiri amagwiritsidwa ntchito popaka utoto wochiritsa komanso inki yochiritsa yopepuka pamodzi ndi epoxy acrylic resin ndi polyurethane acrylic resin.

4. Amino acrylic resin nthawi zambiri amagwiritsidwa ntchito mu zokutira zochiritsira za UV ndi inki zochiritsira za UV pamodzi ndi epoxy acrylic resin ndi polyurethane acrylic resin chifukwa cha kukana bwino kwa kutentha ndi kukana kwa nyengo, kukana mankhwala abwino ndi kuuma kwakukulu.

5. Kujambula zithunzi za alkali sungunuka utomoni ndi utomoni womwe umagwiritsidwa ntchito makamaka pojambula zithunzi zamadzimadzi zokanira inki.Ili ndi magulu a carboxyl ndipo imatha kupangidwa ndikujambulidwa ndi madzi amchere.Mafilimu ochiritsidwa ali ndi mphamvu zabwino kwambiri zamagetsi, kukana mankhwala ndi kukana kutentha.Mitundu yayikulu ndi maleic anhydride copolymer ndi epoxy acrylic resin yosinthidwa ndi maleic anhydride.
