铝板生产厂家讲解铝型材表面油渍和水印的处理

来源:http://www.jndclyyxgs.com

  铝型材表面油痕特征:
  Oil marks on the surface of aluminium profiles:
  铝型材老化前的油渍不清洗,老化后铝水印表面的油渍、氧化后的黑斑及一定深度。
  The oil stains of aluminium profile before aging are not washable, the oil stains on the surface of aluminium watermarking after aging, the black spots after oxidation and a certain depth.
  铝型材表面油痕产生原因:
  The causes of oil marks on the surface of aluminium profiles are as follows:
  (a):成品锯切后铝型材两端油渍,移动(抬起)材料手套不干净,甚至粘有石墨灰。
  (a): After sawing the finished product, the two ends of the aluminium profile are greasy, the gloves of moving (lifting) material are not clean, and even stick to graphite ash.
  (2):铝型材拉伸时手套过长,锯切时材料未取出。
  (2) The gloves are too long when the aluminum profile is stretched and the material is not taken out when sawing.
  手套很脏,在中间留下“记号”。
  Gloves are dirty, leaving a "mark" in the middle.
  (四)挤出设备及工具漏油(驱动车辆、提升皮带)
  (4) Oil leakage of extrusion equipment and tools (driving vehicles, lifting belts)
  消除铝型材油痕的方法:
  Method of eliminating oil mark of aluminium profile:
  (一):铝材加工过程中,搬运搬运时手套应保持清洁,及时清除油污。
  (1) In the process of aluminium processing, gloves should be kept clean during handling and removal, and oil contamination should be removed in time.
  (二):拉伸铝时,取好材料。
  (2) When drawing aluminium, take good material.
  (3):搬运物料时,抬取和移动手套及拉伸取料时,添加手套时应分开。

  (3) When handling materials, when lifting and moving gloves and drawing materials, add gloves separately.
  (4)设备、工具注意漏油,垫纸垫条吊带清洁。
  (4) Pay attention to oil leakage of equipment and tools, and clean the paper cushion strip and suspension belt.

  铝型材水印的特点:
  The characteristics of watermarking for aluminium profile:
  铝型材表面出现银灰色湿印斑点。
  Silver grey wet spot appeared on the surface of aluminium profile.
  铝型材表面水印产生的原因:
  Causes of Watermarking on Aluminum Profile Surface:
  铝型材表面部分被水和雨水浸透,型材表面淬火氧化层的小孔渗透到铝基体中形成三羟基铝酸盐,随着保水时间的延长,三羟基铝酸盐呈亮而弱的状态。如果水中有杂质(盐、亚硝酸盐等),就会产生腐蚀斑点。
  The surface of aluminium profile is partly soaked by water and rainwater. The pore of quenched oxide layer penetrates into the aluminium matrix to form trihydroxyaluminate. With the prolongation of water holding time, the trihydroxyaluminate appears bright and weak. If there are impurities in the water (salt, nitrite, etc.), corrosion spots will occur.
  铝型材表面水印去除:
  Watermarking removal of aluminium profile surface:
  (I):湿铝型材必须立即干燥,老化前必须干燥。
  (I): The wet aluminium profile must be dried immediately and must be dried before aging.
  (2)在条件允许的情况下,增加碱洗时间和氧化膜厚度。
  (2) Increase alkali washing time and oxide film thickness when conditions permit.
  油渍和水渍只要铝型材在老化前不沾灰尘擦拭干净就不会产生油渍和水印,关键是养成良好的操作习惯和质量意识,除此之外。
  Oil stain and water stain will not occur as long as aluminium profile is wiped clean without dust before aging. The key is to develop good operating habits and quality awareness, in addition.
