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.

選材時確定材料品種是重要步驟，辨別材質質量則是選材的要點和重 點。作為鋁合金型材，一定要達到標準的厚度、耐抗拉性。而鋼化玻璃則要求抗拉性達到普通玻璃的3倍以上，抗沖擊力達到普通玻璃的5倍以上。肯德基門噴涂工藝之粉末噴涂，是用噴粉設備在靜電作用下，把粉末涂料噴涂到肯德基門表面，形成粉狀涂層。

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.

肯德基門粉狀涂層經過高溫烘烤，變成效果各異、美觀耐用、防化學侵蝕及紫外線的終涂層。肯德基門的這種噴涂效果在機械強度、附著力、耐腐蝕、耐老化等方面都優于噴漆工藝。肯德基門門噴涂工藝之電泳噴涂，是將涂裝漆溶解在電泳溶劑里并通電。由于電泳現象的產生，使帶電的涂料覆著于肯德基門表面。這種肯德基門噴涂效果，漆膜附著力強、均勻致密、耐蝕性佳，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.
