目前,根据不同用途的pcm彩涂板,随其基板与涂料品种的改变,可选配不同类型的转化膜。pcm彩涂板在我国的很多行业中已经逐渐的得到运用,并且取得了很好的成绩和应用,如,高效施工、节约能源、减低污染等。那么,在我们生产和生活中最为常见的几种pcm彩涂板有哪些类型呢?

At present, according to the different uses of pcm color coating board, with the change of its substrate and coating varieties, different types of conversion film can be selected.The pcm color coating board has been gradually used in many industries in China, and has achieved good results and applications, such as efficient construction, energy saving, pollution reduction, etc.So, what are the types of pcm color coating boards most common in our production and life?

影响pcm彩涂板的耐蚀性因素很多,涉及到彩涂板基板的种类,镀层种类、厚度、涂层种类、层次、厚度,使用环境条件以及应用中的机械加工、运输、保管、施工安装和施工后维护保养等诸多方面的因素。

There are many factors affecting the corrosion resistance of pcm color coating board, involving the types of color coating board substrate, coating type, thickness, layer, thickness, use of environmental conditions and the application of mechanical processing, transportation, storage, construction, installation and maintenance and many other factors.

大多数客户在选择彩涂钢板只关注了涂层要求,而常常忽略基板要求。实际上,基板的防腐性能是彩涂钢板防腐的关键。锌层越厚,腐蚀性介质越难以穿透涂层到达钢板,从而彩涂钢板的耐腐蚀性会更好。

Most customers choose color coated steel plate only focus on the coating requirements, and often ignore the substrate requirements.In fact, the anti-corrosion performance of the substrate is the key to color coated steel corrosion.The thicker the zinc layer, the more difficult it is for the corrosive media to penetrate the coating to the steel plate, and thus the better corrosion resistance.

至于基板应该选择热浸纯锌或热浸铝锌,则主要取决于环境的pH值。锌和铝都是两性金属,但是它们在酸和碱中的性能不同。

As for the substrate should be selected hot dip pure zinc or aluminum zinc, it mainly depends on the pH value of the environment.Zinc and aluminum are both amphotropic metals, but their properties differ in acids and bases.

在碱性介质中,纯锌的性能优于铝锌合金。在酸性介质中的性能恰好相反,热浸铝锌优于热镀锌。

In alkaline media, pure zinc performs better than aluminum-zinc alloys.In contrast in acidic media, hot dip aluminum zinc is better than hot dip galvanizing.

因此,在选择彩涂钢板的过程中,我们建议在相对酸性的使用环境中使用镀铝锌为基板的彩涂钢板。对于相对碱性的环境,我们建议使用热镀锌为基板的彩涂钢板。

Therefore, in the process of choosing a color-coated steel plate, we suggest the use of aluminum-coated zinc-coated steel plate as a substrate in a relatively acidic use environment.For relatively alkaline environments, we recommend using hot coated ized ized ized as ized substrate.
