淺析外墻保溫系統中導致抹面砂漿開裂的原因

隨著鋁板冶煉生產技術的成熟，這一性價比高的金屬材料便迅速進入人們生產生活的方方面面，成為傳統金屬的替代品；而在某些傳統行業，鋁板的市場前景尤為廣泛。鋁板表面劃傷是鋁板加工過程中比較容易發生的事，往往是因為加工處理不當，導致表面受創，嚴重影響到了鋁板的美觀性，不過劃痕已經出現了，下面介紹一下鋁板表面出現瑕疵的處理方法。

With the maturity of aluminum plate smelting production technology, this cost-effective metal material has quickly entered all aspects of people's production and life and become a substitute for traditional metals; In some traditional industries, the market prospect of aluminum plate is particularly broad. Scratch on the surface of aluminum plate is a relatively easy thing to happen in the process of aluminum plate processing. It is often due to improper processing, resulting in surface damage, which seriously affects the beauty of aluminum plate. However, scratch has appeared. The following describes the treatment methods for defects on the surface of aluminum plate.

鋁板外表劃傷能處理，簡略的說有物理和化學兩種辦法：物理辦法便是機械打磨，詳細有噴砂，拉絲等，一般對于較深的劃痕選用這種辦法。化學辦法一般選用化學試劑來拋光，簡略的講便是選用化學試劑將鋁材外表腐蝕掉一層，劃痕處由于有銳邊，腐蝕速度快，較輕的劃痕在化學拋光后能完全消除，化學拋光的材料外表光亮，好看。一般兩種方法配合起來用，鋁材外表能到達很好的裝飾效果。

The scratch on the surface of aluminum plate can be treated. In brief, there are two physical and chemical methods: physical method is mechanical grinding, including sand blasting, wire drawing, etc. generally, this method is used for deeper scratches. Generally, chemical reagent is used for polishing. In brief, chemical reagent is used to corrode one layer of aluminum surface. Due to sharp edges at the scratch, the corrosion speed is fast. Lighter scratches can be completely eliminated after chemical polishing. The appearance of chemically polished materials is bright and good-looking. Generally, when the two methods are used together, the aluminum surface can achieve a good decorative effect.

1、鋁板模具上的工作帶需要打磨光滑，擠壓模具的空刀是否足夠，表面是否光滑。

1. The working belt on the aluminum plate die needs to be polished smooth, whether the empty knife of the extrusion die is enough and whether the surface is smooth.

2、在鋁板鋸切過程中：每次鋸切需要及時清理鋸切的切削鋸末，防止二次劃傷；同理在CNC加工鋁板的過程中，也需要防止夾治具上面殘留的鋁渣劃傷。

2. In the process of aluminum plate sawing: each sawing needs to clean the cutting sawdust in time to prevent secondary scratch; Similarly, in the process of CNC processing aluminum plate, it is also necessary to prevent the residual aluminum slag scratch on the clamping fixture.

3、在生產合金鋁板的過程中，注意模具線條的產生，一旦產生線條，需要及時下模具，停止生產。

3. In the process of producing alloy aluminum plate, pay attention to the generation of mold lines. Once lines are generated, the mold needs to be removed in time to stop production.

4、出料軌道或擺床上有裸露的工業鋁型材或石墨條內有較硬的夾雜物，應避免硬雜物與鋁板接觸時對鋁板表面造成劃傷。

4. There are exposed industrial aluminum profiles or graphite strips on the discharge track or swing bed, and there are hard inclusions in them. It is necessary to avoid scratching the surface of the aluminum plate when hard sundries contact the aluminum plate.

5、在生產和搬運的過程中要輕拿輕放，盡量避免隨意拖動或翻動鋁板，合理擺放鋁板，盡量避免相互摩擦。

5. In the process of production and handling, handle with care, try to avoid dragging or turning the aluminum plate at will, place the aluminum plate reasonably, and try to avoid mutual friction.

除了以上五點，鋁板的貯存也很關鍵，嚴禁與化學材料和潮濕性材料一同存放，很容易發生化學反應，這樣做可以有效避免，其貯存環境應干燥、明亮,通風良好,無腐蝕氣候，主要還是防止鋁板受潮發生氧化反應，影響正常使用。

In addition to the above five points, the storage of aluminum plate is also very important. It is strictly prohibited to store with chemical materials and moist materials, which is prone to chemical reaction. This can be effectively avoided. The storage environment should be dry, bright, well ventilated and free of corrosive climate. The main thing is to prevent the oxidation reaction of aluminum plate from moisture and affect its normal use.
