幕墻鋁板
Curtain wall aluminum plate
1、幕墻鋁板一般指表面經(jīng)過高溫烤漆處理的單層鋁板、鋁塑復合板、蜂窩鋁板等。幕墻鋁板在使用過程中，由于受空氣污染(汽車尾氣及工業(yè)區(qū)空氣污染物)、灰塵及酸雨的共同作用，作為建筑外墻，使用一段時間后便逐漸附著大量雨筋及污垢，影響建筑外觀。同時由于污染物中含有微酸性物質(zhì)可導致鋁板表面烤漆保護膜層被侵蝕，含有大量有機污染物的灰塵和酸雨的流淌，導致污漬容易粘附在鋁板上，一旦污染形成，就會變得很難清洗。
1. Curtain wall aluminum panels generally refer to single-layer aluminum panels, aluminum plastic composite panels, honeycomb aluminum panels, etc. whose surfaces have undergone high-temperature paint treatment. During the use of curtain wall aluminum panels, due to the combined effects of air pollution (car exhaust and industrial air pollutants), dust, and acid rain, as building exterior walls, a large amount of rain reinforcement and dirt gradually adhere after a period of use, affecting the appearance of the building. At the same time, due to the presence of slightly acidic substances in the pollutants, the paint protection film on the surface of the aluminum plate can be eroded, and the flow of dust and acid rain containing a large amount of organic pollutants makes it easy for stains to adhere to the aluminum plate. Once pollution forms, it becomes difficult to clean.
還有就是幕墻鋁板經(jīng)不適當清洗(強酸清洗)后變得有些地方干凈、有些地方比原來還臟，整體的幕墻立面出現(xiàn)大面積發(fā)花的現(xiàn)象。
Another issue is that after improper cleaning (strong acid cleaning), some areas of the aluminum curtain wall panels become clean and some areas are even dirtier than before, resulting in large areas of blooming on the overall facade of the curtain wall.
針對以上原因，鋁板廠家結(jié)合多年的產(chǎn)品生產(chǎn)及施工經(jīng)驗，制定了一套完整的舊幕墻鋁板、舊鋁塑板飾面翻新方案，并得到實施，用戶對我公司的針對性方案評價較好，并作推廣。
In response to the above reasons, aluminum panel manufacturers have developed a complete renovation plan for old curtain wall aluminum panels and old aluminum plastic panels based on years of product production and construction experience, which has been implemented. Users have evaluated our company's targeted plan well and promoted it.
2、優(yōu)勢：免除拆卸原有板材返廠涂裝，減小使用單位維護費用。
2. Advantage: Eliminates the need to dismantle existing panels and return them to the factory for painting, reducing maintenance costs for users.
根據(jù)鋁單板原有涂層的粉化等級和原涂裝工藝做如下工藝：
According to the pulverization level of the original coating on aluminum veneer and the original coating process, the following process is carried out:
1、物理打磨：(適用于粉化等級≤3級的幕墻)。采用打磨工具將被涂物表面打磨粗糙。要 求打磨力度均勻，不得有漏打，不得打穿原涂層;
1. Physical polishing: (suitable for curtain walls with a pulverization level ≤ 3). Use polishing tools to polish the surface of the coating to a rough surface. The polishing force is required to be uniform, without missing or penetrating the original coating;
2、介格縫處理：將原縫硅膠都清除或采用粘貼保護的方式進行 保護;
2. Interlayer joint treatment: Remove all silicone from the original joint or use adhesive protection for protection;
3、封閉基層：采用高附著力專用滲透底漆封閉原涂層的微孔、析出物等;
3. Sealing the base layer: Use a high adhesion specialized penetrating primer to seal the micropores, precipitates, etc. of the original coating;
4、面漆噴涂：均勻的噴涂面層兩遍;
4. Top coat spraying: Spray the surface layer twice evenly;

5、分格縫處理：重新打膠保護(或清理)
5. Dividing joint treatment: re gluing for protection (or cleaning)
