二、测试详情

II. Test Details

（一）测试产品及项目

(A) Test Products and Projects

主要测试产品为8170 + 6319，将其应用于涂料中，重点检测其附着力性能。具体检测点设置如下：

The main test product is 8170 + 6319, which is applied in coatings, and its adhesion performance is mainly detected. The specific detection points are set as follows:

80度烘烤后的附着力测试

1. Adhesion test after baking at 80 degrees

- 分别在80度烘烤1小时和2小时后对样板的附着力进行测试。通过不同时间的烘烤，观察涂料在特种超滑冷轧钢板上的附着力变化情况，以评估产品在不同温度和时间条件下的附着稳定性。

- Conduct adhesion tests on the test panels after baking at 80 degrees for 1 hour and 2 hours respectively. Through baking for different times, observe the change in adhesion of the coating on the special super-smooth cold-rolled steel sheet to evaluate the adhesion stability of the product under different temperature and time conditions.

2. 冷凝后附着力测试

2. Adhesion test after condensation

- 先将样板进行80度烘烤2小时，然后放置在40度冷凝箱中。分别在放置200H和384H后，从冷凝箱里拿出来直接进行附着力测试。这种测试条件模拟了产品在实际使用中可能遇到的潮湿和低温环境，检验其在复杂环境下的附着力可靠性。

- First, bake the test panel at 80 degrees for 2 hours, and then place it in a 40-degree condensation box. After being placed for 200 hours and 384 hours respectively, take it out directly from the condensation box and conduct adhesion tests. This test condition simulates the humid and low-temperature environments that the product may encounter in actual use and tests its adhesion reliability in complex environments.

（二）样板规格

2. 附着力测试结果（冷凝后）

2. Adhesion test results (after condensation)

- 当样板耐40度冷凝218H后进行测试，以及耐40度冷凝384H后从冷凝箱里拿出来直接进行测试，结果显示涂料依然保持了较好的附着力。尤其是在384H的长时间冷凝后，其附着力可靠，表明产品在潮湿低温环境下具有出色的耐久性和附着稳定性。

- When the test panel is tested after withstanding condensation at 40 degrees for 218 hours and is directly tested after being taken out of the condensation box after withstanding condensation at 40 degrees for 384 hours, the results show that the coating still maintains good adhesion. Especially after a long time of condensation for 384 hours, its adhesion is reliable, indicating that the product has excellent durability and adhesion stability in humid and low-temperature environments.
