  涂刷防锈漆镀锌材料,一直是一个非常困难的工作,因为它的材料属性和不锈钢,相同的一般外观油漆很难坚持,一点不小心将电影下降的现象,如何确保镀锌管等特殊概要文件漆膜不容易下降将逐渐发展成为人们关注的问题,下面将简要介绍济南镀锌管材型材的涂装及涂装技术,希望对今后的涂装工作有所帮助。

  It has always been a very difficult job to brush antirust paint for galvanized materials, because its material properties and stainless steel, the same general appearance paint is difficult to adhere to, the phenomenon of accidentally dropping the film, how to ensure that the paint film of special profile such as galvanized pipe is not easy to drop, will gradually develop into a problem of concern, The following will briefly introduce the coating and coating technology of Jinan galvanized pipe profiles, hoping to be helpful for the future coating work.

  现在油漆对镀锌管的使用方法较多有两种,一种是对镀锌管外观进行磷酸处理,另一种是使用高附着力的油漆,在涂装前需要做以下处理:

  At present, there are two ways to use paint for galvanized pipe, one is to carry out phosphoric acid treatment for the appearance of galvanized pipe, the other is to use high adhesion paint, and the following treatment needs to be done before coating:

  1. 处理

  1. processing

  所谓磷酸处理就是利用镀锌管表面的磷酸材料进行钝化处理,以提高镀锌管表面的粗糙度和附着力。磷化处理是比较昂贵的,如果有条件可以使用。

  The so-called phosphoric acid treatment is to use the phosphoric acid material on the surface of galvanized pipe for passivation treatment, so as to improve the surface roughness and adhesion of galvanized pipe. Phosphating treatment is more expensive, if conditions can be used.

  2. 使用磷化底漆或高附着力底漆

  2. Use phosphating primer or high adhesion primer

  现在市场上有一种磷化底漆,与磷化处理功能相似,可以在一定程度上提高镀锌管的粗糙度,可以使用磷化底漆等底漆或直接使用中心漆面漆。

  Now there is a kind of phosphating primer on the market, similar to phosphating treatment, which can improve the roughness of galvanized pipe to a certain extent, and can use primer such as phosphating primer or directly use central paint.

  关于镀锌管材,一般选择环氧磷酸锌底漆,环氧锌黄底漆,两者都是涂层附着力好产品,广泛用于镀锌管的底部、不锈钢和其他特殊材料,油漆施工前的镀锌管磨处理,细磨,以防止损坏涂层的镀锌管本身,衬底的选择处理,油漆是防止济南镀锌管锈蚀的关键因素。

  For galvanized pipes, epoxy zinc phosphate primer and epoxy zinc yellow primer are generally selected, both of which are products with good coating adhesion. They are widely used in the bottom of galvanized pipes, stainless steel and other special materials. Before the paint construction, the galvanized pipes are ground and finely ground to prevent damage to the coated galvanized pipes themselves. The selection and treatment of substrate and paint are the key factors to prevent the corrosion of Jinan galvanized pipes.
