Changes in air pressure, ambient temperature, environmental humidity and other factors will not cause bending, deformation or expansion of anti-corrosion and thermal insulation aluminum roll.
表层无复合连续高温压印和残余应力，切割后不会变形。
The surface layer has no composite continuous high-temperature stamping and residual stress, and will not deform after cutting.
耐盐酸酸雨侵蚀，不易侵蚀活菌，不释放有害气体，不易对主要龙骨及固定构件造成侵蚀。
It is resistant to salt, acid and rain erosion, is not easy to erode living bacteria, does not release harmful gas, and is not easy to erode the main keel and fixed components.
经连续高温烘烤后，漆纹仍保持较高的平滑度，色彩稳定性好，色偏小。如果使用聚酯漆，可以保证10年，氟碳喷涂可以保证20年以上。
After continuous high-temperature baking, the paint lines still maintain high smoothness, good color stability and small color deviation. If polyester paint is used, it can be guaranteed for 10 years, and fluorocarbon spraying can be guaranteed for more than 20 years.

防腐保温铝卷表面白点处理
Anti corrosion and thermal insulation aluminum coil surface white spot treatment
防腐保温铝卷的金属活性强，容易被氧化。由于铝皮在氧化时会产生致密的氧化铝膜，可以防止与铝的连续反应。因此，铝皮上出现白点应该是正常现象。对于表面要求严格的铝皮，如何避免表面出现白点，使产品更光滑亮丽，不仅与加工工艺有关，还与后期的表面处理工艺密切相关。
The anti-corrosion insulation aluminum coil has strong metal activity and is easy to be oxidized. As the aluminum coating will produce a dense alumina film during oxidation, it can prevent continuous reaction with aluminum. Therefore, it should be normal for white spots to appear on the aluminum sheet. For aluminum sheet with strict surface requirements, how to avoid white spots on the surface and make the product more smooth and bright is not only related to the processing technology, but also closely related to the later surface treatment technology.
大型铝制品阳极氧化时，加工后表面偶尔会出现白点。隔热铝皮氧化后尤为明显。氧化后水洗不充分会导致干燥后表面出现白点。解决方法如下：氧化后加强清洗，尽量用水枪清洗，清洗后注意保护表面，尽量避免产品与其他产品接触，自然晾干。
When large aluminum products are anodized, white spots occasionally appear on the surface after processing. The thermal insulation aluminum coating is especially obvious after oxidation. Insufficient washing after oxidation will lead to white spots on the dried surface. The solutions are as follows: strengthen cleaning after oxidation, and try to clean with a water gun. After cleaning, pay attention to protecting the surface, try to avoid contact with other products, and dry naturally.
铝卷生产厂家认为要想控制铝皮表面的白点，不仅要在加工产品前注意产品的表面问题，还要注意表面处理过程中的预防，使用标准严格的加工流程和加工工艺，避免形成白点。可以用酸洗和碱洗来清洗白斑，但要控制浓度或喷漆，阻断铝与氧的接触。
Aluminum coil manufacturers believe that in order to control the white spots on the surface of aluminum sheet, they should not only pay attention to the surface problems of products before processing, but also pay attention to the prevention during surface treatment, and use strict standard processing processes and processes to avoid the formation of white spots. Acid and alkali washing can be used to clean the white spots, but the concentration or painting shall be controlled to block the contact between aluminum and oxygen.
