【何謂鍍膜以及為什麼需要鍍膜】

鍍膜（Coating）是泛指利用各種加工方式塗佈機能性材料於被鍍物（基材或工件等）表面，並賦予被鍍物具有特殊機能特性。

例如：抗氧化／耐酸鹼／抗污撥水／易清潔／高硬度／高耐候／特殊外觀性等特性。

而鍍膜方法有非常多種類：PVD（物理氣相沉積）/CVD（化學氣相沉積），噴塗，擦塗，刮塗等均為鍍膜的方法。

一般而言，鍍膜可增加被鍍物之相對厚度，範圍從數個nanometer（奈米）至數百個micrometer（微米）。

所以機能性塗佈材料的選擇（材料本身的均勻性/穩定性/耐候性）與被鍍物之界面作用力是非常重要的，此將影響鍍膜過程中：

1. 成膜之均勻度。

2. 成膜後之穩定性。

3. 機能性被鍍物之機能壽命．而鍍膜於被鍍物上，簡單地可區分為物理作用力或化學作用力兩種。

由於牽扯太多界面科學相關細節，所以在此，即不詳加說明。

例如：針對汽車鈑件市場，蠟品（或含高油脂之樹脂）塗佈於金油鈑件上，其主要之界面鍵結作用力為物理作用力為主。

因此，鍍膜後其機能壽命（高滑水與高亮度等功效）非常短暫。

簡單地說，最適當的機能性材料將能使被鍍物，於其鍍膜後可達到最長效之使用壽命。

而G2F所設計之機能性塗佈材料於不同之被鍍物上，再依照本公司之施工建議或塗佈方式後，其鍍膜後之機能壽命，可達到5-10年甚至10年以上（此機能壽命與鍍膜厚度與使用環境有關）。

 

【What is “coating” and why coating is necessary】

Coating means to provide the special functional characteristics on substrate by using different process. For example, anti-oxidation, acid and alkali-resistance, anti-stain, water repellency, easy to clean, high hardness, weather-proof, special exterior and so on. There are many methods for coating as PVD, CVD, spray, wipe, blade coating…etc.

The coating process can increase relative thickness of the substrate that ranges from tens of nanometer to hundreds of micrometers. Therefore, the selected functional materials and the interface interaction between material and substrate are important. These will influence the coated layer uniformity & stability and lifetime of the function in/after coating process.

        The interactions between the coated layer and substrate can be differentiated the physical & chemical aspects. This includes details of the interface science, so it will not be discussed here. For instance, using wax (or the resin that contained high fatty oil) on automobile metal plate belongs to physical interaction between the metal plate & wax. So, the coated performances that include the effects of water repellency & glossiness & lifetime are shorter. In brief, the most appropriate functional material can provide the most lifetime on coated substrate.

        G2f designs many functional coating materials for different application aspects. If you follow our suggestions and coating methods, the coated substrates will have more lifetime that's up to 5-10 years or even more than 10 years. (it depends on the thickness of coating layer & environmental conditions)
