I-UV 328 iyisishutheli se-UV esingu-290-400nm esinomphumela omuhle wokusimamisa ukukhanya-nge-photochemistry; umkhiqizo unokumunca okuqinile kokukhanya kwe-ultraviolet, umbala wokuqala ophansi embala womkhiqizo, uncibilika kalula ku-plasticizer kanye nohlelo lwe-monomer, uguquguquke kancane, futhi unokuhambisana okuhle nezinto eziningi eziyisisekelo; emikhiqizweni yangaphandle, ingasetshenziswa ne-phenolic antioxidant kanye ne-phosphate ester antioxidant kanye ne-amine photostabilizer evinjiwe.
Ikakhulukazi isetshenziswa polyolefin, PVC, HDPE, styrene olulodwa kanye copolymer, ABS, acrylic polymer, polyester unsaturated, polythermoplastic polyamine, emanzi ephulukisa polyurethane, polyacetal, PVB (polyvinyl butyaldehyde), epoxy kanye polyurethane uhlelo izingxenye ezimbili, uhlelo umshini uzibuthe acrylic acid nopende ibuye isetshenziswe ezimbotsheni zezimoto, ezimbotsheni zezimboni, ezifakwe ngokhuni.
Engeza inani: 1.0-3.0%, inani elithile elengeziwe linqunywa ngokuya ngokuhlolwa kwesicelo sekhasimende.
Ipakishwe esikhwameni sephepha se-kraft esingu-20Kg/25Kg noma ibhokisi.
Gwema ukukhanya kwelanga, ukukhanya okuphezulu, umswakama, nezinzinzisi zokukhanya eziqukethe izakhi zesulfure noma ze-halogen. Idinga ukugcinwa endaweni evalekile, yomile futhi kude nokukhanya.
