The thickness of paint on color-coated aluminum coils is one of the important factors affecting its performance and quality. Too thick or too thin paint thickness will cause defects and problems in color-coated aluminum coils. Too thick paint thickness will increase costs, reduce the hardness and flexibility of the coating, affect the adhesion and corrosion resistance of the coating, and easily produce defects such as Širjenje, gube in mehurčki . Preveč tanka debelina barve bo zmanjšala pokritost in skrivanje moči prevleke, vplivala na barvo in sijaj prevleke ter zlahka ustvarila okvare, kot so praske, obraba in luščenje .
Dejavniki, ki vplivajo
Zato je nadzor nad debelino barvnih aluminijastih tuljav ključna povezava, ki zagotavlja njegovo kakovost in zmogljivost . debelina barv aluminijastih tuljav barvno prevlečeno na barvno prevlečeno, predvsem pa naslednji:
Kakovost surovin in površinsko obdelavo
Kakovost surovin in površinsko obdelavo neposredno vplivajo na trdnost in ravnost prevleke ter podlago . surovine z ustreznimi serijami zlitin, trdoto, debelino in drugimi parametri je treba izbrati, in jih je treba očistiti, predhodno obpraviti in pripraviti (dokončati), da bi izboljšali korozijsko odpornost in oprijem zgornje barve .
Vrste in značilnosti barve
Coatings of different types and properties have different requirements for paint thickness. Usually, according to the classification of paint used for organic coatings, aluminum coils include PVC painted aluminum coils, polyester painted aluminum coils, acrylic painted aluminum coils, fluorocarbon painted aluminum coils, silicone polyester painted aluminum Tuljave itd.
Postopek in oprema premaza
Different coating processes and equipment have different control accuracy for coating thickness. According to different coating methods, organic coated aluminum coils have roller coating, spraying, powder coating, laminating and printing. Among them, roller coating is the most commonly used method, which evenly distributes the pre-mixed paint on the substrate through a roller, and forms a continuous and Enotni barvni film po peki in strjevanju . parametri, kot so oblika valja, velikost, hitrost vrtenja, vrzel itd. . bodo vplivali
Povzetek
Če povzamemo, debelina barveBarvno prevlečene aluminijaste tuljaveje zapleteno in pomembno vprašanje, ki ga je treba izčrpno upoštevati v skladu z dejavniki, kot so uporaba izdelkov, zahteve glede zmogljivosti in nadzor stroškov, za spremljanje in uravnavanje .
