前言涂料形成涂膜之后,有许多功能,主要是它既能防锈、防腐蚀又可防渗透、防导电。涂料的特点是,涂装时不因被涂物体大小或形状复杂而受限制,使用方便,费用低。因此应用广泛,并容易维修。这些优点是其他包覆材料不能相比的。所以在今后相当长时间内,仍是一种主要防腐手段。涂料一般不能用简单结构式表示。它不是 Preface Paint after the formation of coating, there are many functions, mainly because it can not only rust, corrosion and anti-infiltration, anti-conductive. Paint is characterized by the coating is not subject to the size or shape of the object due to the complexity of the complex, easy to use, low cost. Therefore widely used and easy to repair. These advantages can not be compared with other coating materials. Therefore, for a long time to come, this is still a major anti-corrosion measure. Paint generally can not be expressed by a simple structure. It is not
