  为进步铝合金型材基体与涂层的附着力,基材在喷涂前有必要选用多级清洁及前处置系统以除掉金属外表的有机、无机污物和堆积的氧化物,并涂附一层化学转化,基材预处置质量的好坏可直接影响涂层的有关功能,因此,惯例、疾速的前处置查看显得很要害。基材预处置的查验通常分为除油作用的查验和化学转化膜外表质量和厚度查验。除油作用的查验可选用目视法,调查铝基材外表有无污迹,水膜是不是接连,是不是挂水珠。前处置除油结束的铝基材外表应无污迹,水膜接连,不挂水珠。化学转化膜的查验可参阅GB/T9792《金属材料上的化学转化膜单位面积上膜层质量的测定重量法》进行查看,铬化或磷铬化膜不该起粉。

  粉末喷涂型材装饰面上的涂层应滑润、均匀,不答应有皱纹、气泡、流痕、发粘、针孔、露底、起粉、粉不全、尘粒、划伤、膜掉落、起骨和凹影等缺点。答应存在细微的桔皮、缩孔、混色、粉粒表象,其答应程度通常应由供需双方商定的实物标样标明。粉末喷涂型材的外观质量查验选用正常的视力,在天然散射光条件下,距涂层lm间隔,成90°的视点调查涂层外表。因为型材的形状和涂层品种不一样,不一样的调查间隔和不一样的视点方位,区分的成果均区别。表6—3—25是国内外规范中涂层外观质量的查看办法比照。

  颜色和色差查验的查验办法有两种,即目视法和色差仪法。通常情况下选用目视法,按GB/T9761—1988《色漆和清漆色漆的目视比色》中3.2条及6.1条规则,对照规范色板进行查看。单色涂层裁定时选用色差仪,按GB/Tlll86.2《漆膜颜色的丈量办法》的规则测定。=

  1.目视法

  1)比色光源需求关于日常的比色工作,可选用天然日光或人工日光。但天然光的性质是不稳定的,并且调查者的判别也易受周围五颜六色物体的影响,关于出产公司的夜晚出产现场的质量操控也不可能选用天然日光。因此通常用比色箱的人工日光光照和天然日光比照选用,以比色箱的人工日光光照为主要比色光源。比色箱的光源照在试板上所具有的光谱能量散布应与CIE规范光源D65相近似。

  2)调查者需求调查者不能有视觉缺点,应经过色盲查看后才干上岗。为了防止双眼疲劳的影响,在看了激烈的颜色后,不要当即看淡色。在对亮堂的饱和色进行比照时,如不能迅速作出断定,应在旁边的中性灰色上看上几秒钟,以后再进行比色。
