下面换热器网跟大家谈谈螺旋板式换热器防腐蚀方法。

螺旋板式换热器中,如何来进行防腐蚀处理呢?一般有哪些方法呢?下面换热器网就来简单进行一下说明,具体内容如下。

它有阴极保护和阳极保护这两种,不过常采用的是牺牲阳极保护技术,但是它也有缺点,那就是不能实施到管内深处,仅仅只能够作用到管子入口处的有限长度,所以其应用有一定的限制。

使用耐腐蚀材料,虽然能够有效,但是其成本高,一次性投入比较大,因此其使用不是很多。

就是在其表面覆盖一层涂料保护层,这样就可以避免直接接触了。因此,其是非常有效的,而且涂料种类可以进行选择,以便来满足不同的要求。

Spiral plate heat exchanger, how to carry out anti-corrosion treatment? What are the general methods? The following heat exchanger network to simply carry out the instructions, the specific content is as follows.

It has two kinds of cathodic protection and anodic protection, but it is often used in the sacrificial anode protection technology, but it also has shortcomings, it is not implemented into the tube, only to be able to function to the entrance of the pipe limited length, so its application has a certain limit.

Use of corrosion-resistant materials, although it can be effective, but the cost is high, the one-time investment is relatively large, so its use is not a lot of.

Is to cover a layer of paint on its surface, so that you can avoid direct contact. Therefore, it is very effective, and the type of paint can be chosen in order to meet the different requirements.
