采用優質鋁材、塑料和粘合劑，采用的加工工藝，具有裝飾面板所需的抗拉強度，氣壓、環境溫度、環境濕度等因素的變化不會造成防腐保溫鋁卷彎曲，變形或膨脹。
It adopts high-quality aluminum, plastic and adhesive, and adopts professional processing technology. It has the tensile strength required for decorative panels. 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.
表層無復合連續高溫壓印和殘余應力，切割后不會變形。
The surface layer has no composite continuous high-temperature stamping and residual stress, and will not deform after cutting.
耐鹽酸酸雨侵蝕，不易侵蝕活菌，不釋放有害氣體，不易對主要龍骨及固定構件造成侵蝕。
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.
經連續高溫烘烤后，漆紋仍保持較高的平滑度，色彩穩定性好，色偏小。如果使用聚酯漆，可以保證10年，氟碳噴涂可以保證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.

防腐保溫鋁卷表面白點處理
Anti corrosion and thermal insulation aluminum coil surface white spot treatment
防腐保溫鋁卷的金屬活性強，容易被氧化。由于鋁皮在氧化時會產生致密的氧化鋁膜，可以防止與鋁的連續反應。因此，鋁皮上出現白點應該是正常現象。對于表面要求嚴格的鋁皮，如何避免表面出現白點，使產品更光滑亮麗，不僅與加工工藝有關，還與后期的表面處理工藝密切相關。
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.
大型鋁制品陽極氧化時，加工后表面偶爾會出現白點。隔熱鋁皮氧化后尤為明顯。氧化后水洗不充分會導致干燥后表面出現白點。解決方法如下：氧化后加強清洗，盡量用水槍清洗，清洗后注意保護表面，盡量避免產品與其他產品接觸，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.
鋁卷生產廠家認為要想控制鋁皮表面的白點，不僅要在加工產品前注意產品的表面問題，還要注意表面處理過程中的預防，使用標準嚴格的加工流程和加工工藝，避免形成白點。可以用酸洗和堿洗來清洗白斑，但要控制濃度或噴漆，阻斷鋁與氧的接觸。
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.
