Ixabiso elihle UV Absorber UV 144 cas 63843-89-0
Umqalisi wokukhanya (ifotoinitiator), ekwabizwa ngokuba yi-photosensitizer (photosensitizer) okanye iarhente yokunyanga ukukhanya (i-ejenti yokufota), luhlobo lweekhompawundi zekhemikhali ezinokufunxa amaza athile amandla, zivelise i-radical yasimahla kunye ne-cationic kwingingqi ye-uv (250 ~ 420 nm. ) okanye indawo yokukhanya ebonakalayo (400 ~ 800 nm) ukuqaliswa kwe-monomerization ye-crosslinking curing.
I-UV144 sisizinzi se-amine esithintelweyo kunye nokuziphatha okuthintelweyo kwephenolic antioxidant. Imveliso inokukhusela i-coating kwi-craking kunye nokulahlekelwa kokukhanya ukuya kwinqanaba elithile, ngaloo ndlela yandisa kakhulu ubomi benkonzo yefilimu yepeyinti.Ikwathintela i-resin yellowing ebangelwa ukubhaka okuphezulu kokushisa.
I-stabilizer yokukhanya inokongezwa kwi-coating ephakathi kunye ne-lacquer yokugubungela kwipeyinti yemoto ephindwe kabini. Ngokwamava ethu, i-stabilizer yokukhanya yongezwa kumaleko aphezulu wengubo ukuze idlale umphumo ogqwesileyo wokukhusela.
Kwiingubo zomgubo, i-UV144 inokudlala indima yokutshaja i-friction ye-powder coatings, enokuzisa ezi zibonelelo zilandelayo:
Ukunyusa izinga le powder caoting kwi-friction eletrostatic spraying kunye nokunciphisa ukubuyiswa komgubo.
Ukwandisa ukunamathela phakathi kwengubo yomgubo kunye ne-workpiece.
Ukuphucula "i-cladding" kwi-workpiece ekuthandazeni.
Gcina isikhongozeli sivalwe ngokuqinileyo. Kuphephe ukungeniswa kunye nokuphefumla.
