KFC door materials should be selected appropriately. The so-called appropriate means that the material itself should be strong, durable and stable. According to the current market practice, the door frame material used in KFC door processing should be aluminum alloy profile, because its cross-section size is accurate and the processing accuracy is high. Tempered glass is generally used because of its high strength and good heat resistance.

选材时确定材料品种是重要步骤，辨别材质质量则是选材的要点和重 点。作为铝合金型材，一定要达到标准的厚度、耐抗拉性。而钢化玻璃则要求抗拉性达到普通玻璃的3倍以上，抗冲击力达到普通玻璃的5倍以上。肯德基门喷涂工艺之粉末喷涂，是用喷粉设备在静电作用下，把粉末涂料喷涂到肯德基门表面，形成粉状涂层。

Determining the material variety is an important step in material selection, and identifying the material quality is the key point and focus of material selection. As an aluminum alloy profile, it must meet the standard thickness and tensile resistance. The tensile strength of tempered glass is required to be more than 3 times that of ordinary glass, and the impact resistance is more than 5 times that of ordinary glass. The powder spraying of KFC door spraying process is to use powder spraying equipment to spray powder coating on the surface of KFC door under the action of static electricity to form a powder coating.

肯德基门粉状涂层经过高温烘烤，变成效果各异、美观耐用、防化学侵蚀及紫外线的终涂层。肯德基门的这种喷涂效果在机械强度、附着力、耐腐蚀、耐老化等方面都优于喷漆工艺。肯德基门门喷涂工艺之电泳喷涂，是将涂装漆溶解在电泳溶剂里并通电。由于电泳现象的产生，使带电的涂料覆着于肯德基门表面。这种肯德基门喷涂效果，漆膜附着力强、均匀致密、耐蚀性佳，而且符合。

After baking at high temperature, KFC door powder coating becomes a final coating with different effects, beautiful and durable, anti chemical erosion and ultraviolet radiation. The spraying effect of KFC door is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance and aging resistance. The electrophoretic spraying of KFC door spraying process is to dissolve the coating paint in electrophoretic solvent and energize it. Due to the electrophoretic phenomenon, the charged coating is covered on the surface of KFC door. The KFC door has good spraying effect, strong adhesion, uniform and dense paint film, good corrosion resistance and environmental protection.
