Chromization Process for Powder Coating.
Powder coating is a dry finishing process that uses finely ground particles of pigment and resin, which are electrostatically charged and sprayed onto the surface to be coated. The charged particles adhere to the surface and then undergo a curing process to form a durable, protective coating. Chromate conversion coating (Chromization) is a chemical process that is often used as a pre-treatment for powder coating. Chromization improves the adhesion and corrosion resistance of the powder coating.
The basic steps in the chromization process for powder coating are as follows:
1. Surface preparation: The surface to be coated is cleaned and degreased to remove any contaminants that could
interfere with the adhesion of the chromate conversion coating.
2. Chromate conversion coating: The surface is immersed in a chromate conversion coating solution. The solution contains chromic acid, which reacts with the surface of the metal to form a thin, protective layer of chromium oxide.
3. Rinsing: The chromate conversion coating is rinsed with water to remove any residual chemicals.
4. Drying: The surface is dried to remove any moisture.
5. Powder coating: The chromate conversion coated surface is then powder coated using a standard powder coating process.

粉末喷涂的钝化基本流程。

粉末喷涂是一种干式涂装工艺，它使用经过良好研磨的颜料和
树脂颗粒，这些颗粒带静电并喷涂到待涂层的表面上。

带电颗粒粘
附在表面上，然后经过固化过程形成耐用保护涂层。

铬酸盐转化膜（钝化）是一种化学工艺，通常用作粉末涂层的预处理。

钝化可提
高粉末涂层的附着力和耐腐蚀性。

粉末涂层钝化工艺的基本步骤如下：
1. 表面处理，待涂层的表面经过清洁和脱脂，以去除可能妨碍
铬酸盐转化膜附着的任何污染物。

2. 铬酸盐转化膜，将表面浸入铬酸盐转化膜溶液中。

该溶液含
有铬酸，它与金属表面反应形成一层薄的、保护性的氧化铬层。

3. 冲洗，用清水冲洗铬酸盐转化膜，去除任何残留的化学物质。

4. 干燥，将表面干燥以去除任何水分。

5. 粉末涂装，然后使用标准的粉末涂层工艺对铬酸盐转化膜表
面进行粉末涂装。
