電泳涂裝:若電泳涂裝不嚴格符合各種工藝工藝的要求,如烘烤時間長槽液污染槽液成分不合格等。鋁型材表面為粗糙發(fā)泡針孔或收縮清漆色斑低光澤不均勻的漆膜,型材表面有裂紋等表面缺陷。

Electrophoretic coating: If the electrophoretic coating does not strictly meet the requirements of various processes, such as long baking time, contamination of the tank liquid, and unqualified composition of the tank liquid. The surface of aluminum profiles is a rough foaming pinhole or a paint film with low gloss and uneven shrinkage varnish spots, and there are surface defects such as cracks on the profile surface.

陽極氧化:氧化膜易與雜質(zhì)混合,變黃;材料易粘在一起,使型面氧化顏色不均勻,形成彩虹色,造成產(chǎn)品外觀不良;型面和冷床易形成黑色。K點或白點;電解液溫度過高或電解時間過長,造成鋁型材表面。白色不透明粉末;在氧化過程中,如果剖面下降,容易引起短路;如果堿腐蝕時硫酸濃度控制不好,則剖面表面的耐腐蝕性會降低;氧化膜表面也容易發(fā)生。骨灰發(fā)黑或外觀質(zhì)量問題。

Anodizing: The oxide film is easily mixed with impurities and turns yellow; The materials are easy to stick together, causing uneven oxidation color on the surface, forming a rainbow color, and causing poor product appearance; The profile and cooling bed are prone to forming black. K dots or white dots; High electrolyte temperature or prolonged electrolysis time can cause the surface of aluminum profiles. White opaque powder; During the oxidation process, if the profile decreases, it is easy to cause short circuits; If the concentration of sulfuric acid is not well controlled during alkaline corrosion, the corrosion resistance of the profile surface will decrease; The surface of the oxide film is also prone to occurrence. Blackening of ashes or appearance quality issues.

粉末涂料:如果原料的質(zhì)量不好,有粉塵或雜質(zhì)混入,會在型材表面產(chǎn)生顆粒;壓縮空氣不干凈,與油或水混合也會造成鋁型材表面的收縮缺陷;不合理的匹配會影響鋁型材產(chǎn)品的物理性能和耐化學性,如硬度,抗沖擊性和抗彎性;它還會導致型材表面外觀不良而沒有粉末和變黃。

Powder coating: If the quality of the raw materials is poor and there is dust or impurities mixed in, particles will be generated on the surface of the profile; Compressed air that is not clean and mixed with oil or water can also cause shrinkage defects on the surface of aluminum profiles; Unreasonable matching can affect the physical properties and chemical resistance of aluminum profile products, such as hardness, impact resistance, and bending resistance; It can also cause poor appearance of the profile surface without powder and yellowing.
