我们在利用保温铝板进行操作时可能会遇到保温铝板被氧化的情况,这种情况我们该如何进行处理呢?
When we operate with insulated aluminum plate, we may encounter the oxidation of insulated aluminum plate. How should we deal with this situation?
(1)热水冲洗。热水洗目的是老化膜层。但水温和时间要严格控制,水温过高膜层减薄,颜色变淡。工业保温铝板处理时间过长也会出现上述类似问题,适宜的温度和时间是:温度40~50℃时间0.5~1MIN.
(1) Rinse with hot water. The purpose of hot water washing is to aging the film. However, the water temperature and time shall be strictly controlled. If the water temperature is too high, the film becomes thinner and the color becomes lighter. The above-mentioned similar problems will also occur when the treatment time of industrial thermal insulation aluminum plate is too long. The appropriate temperature and time are: temperature 40 ~ 50 ℃ and time 0.5 ~ 1min
(2)干燥。干燥以自然晾干为好,经热水冲馅稞的工件斜挂于架子上,让工作表面的游离水以陲直方向向下。流至下端角边的水珠用毛巾吸去,按此法晾干的膜层色彩不受影响,显得自然。
(2) Dry. It is better to dry naturally. The workpiece filled with barley washed by hot water is hung obliquely on the shelf, so that the free water on the working surface is downward in a straight direction. The water drops flowing to the lower corner are absorbed with a towel. The color of the film dried by this method is not affected and appears natural.


(3)老化。保温铝板老化方法可根据气候条件来决定,有日光的夏季可在日光下曝晒,阴雨天或是冬季可用烘箱烘烤,工艺条件是:温度40~50℃时间10~15min.
(3) Aging. The aging method of thermal insulation aluminum plate can be determined according to the climatic conditions. It can be exposed to the sun in summer with sunlight. It can be baked in an oven in cloudy and rainy days or winter. The process conditions are: temperature 40 ~ 50 ℃ and time 10 ~ 15min
(4)不合格件的返修。不合格导电氧化膜件宜在干燥、老化工序之前先挑出来,因干燥、老化后膜层较难退除并会影响工件表面的粗糙度。我们可以先将不合格的工件夹在铝阳极氧化用的夹具上,然后按铝在硫酸溶液中的阳极氧化方法进行阳极处理2~3min,待膜层松软、脱落,再经碱液稍加清洗及硝酸出光后即可重新进行导电阳极化。
(4) Repair of nonconforming parts. Unqualified conductive oxide film parts should be picked out before drying and aging process, because it is difficult to remove the film after drying and aging and will affect the surface roughness of the workpiece. We can first clamp the unqualified workpiece on the fixture for aluminum anodizing, and then conduct anodizing according to the anodizing method of aluminum in sulfuric acid solution for 2 ~ 3min. After the film is soft and falls off, we can conduct conductive anodizing again after a little cleaning with alkali solution and nitric acid.
