PA-3: a multifunctional cleaning agent, which can quickly clean rust and scale on the surface of the workpiece, and can form a protective film on the surface of the workpiece with a certain antirust function Because acid liquor is easy to remain in the interlayer or gap, even after phosphating treatment, the crack is still easy to return to rust. However, PA-3 can solve this problem well, and a protective film can be formed at the same time of pickling and rust removal, which can play a protective role.

PA-3性能測試
一、實驗內容
1、工藝:酸洗—水洗—水洗—中和—水洗—封閉處理
2、板材:熱軋鋼(鏽蝕嚴重)
3、塑粉:室外粉
4、工作液參數:
| 配比(g/L) | 溫度(℃) | 時間(min) |
| 200 | 50 | 5~10 |
5、測試項目:
| 測試項目 | 測試方法 |
| 裸膜耐蝕性能 | 自然陰幹 |
| 塗層附着力 | 百格測試 |
二、實驗結果與分析:
| 測試項目 | 測試結果 |
| 100h裸膜耐蝕性 | 不鏽 |
| 百格測試 | 無脫落 |

裸膜圖片(100h自然陰幹)
可清晰的看到,除盡鐵鏽和氧化皮的鋼鐵表面生成一層淡黃色的膜層。

百格測試圖片
顯而易見,百格測試塗層無脫落,附着力評級0級。
