目前，根據(jù)不同用途的pcm彩涂板,隨其基板與涂料品種的改變,可選配不同類型的轉(zhuǎn)化膜。pcm彩涂板在我國的很多行業(yè)中已經(jīng)逐漸的得到運用，并且取得了很好的成績和應(yīng)用，如，高效施工、節(jié)約能源、減低污染等。那么，在我們生產(chǎn)和生活中最為常見的幾種pcm彩涂板有哪些類型呢？
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?
影響pcm彩涂板的耐蝕性因素很多，涉及到彩涂板基板的種類，鍍層種類、厚度、涂層種類、層次、厚度，使用環(huán)境條件以及應(yīng)用中的機械加工、運輸、保管、施工安裝和施工后維護保養(yǎng)等諸多方面的因素。
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.
大多數(shù)客戶在選擇彩涂鋼板只關(guān)注了涂層要求，而常常忽略基板要求。實際上，基板的防腐性能是彩涂鋼板防腐的關(guān)鍵。鋅層越厚，腐蝕性介質(zhì)越難以穿透涂層到達鋼板，從而彩涂鋼板的耐腐蝕性會更好。
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.
至于基板應(yīng)該選擇熱浸純鋅或熱浸鋁鋅，則主要取決于環(huán)境的pH值。鋅和鋁都是兩性金屬，但是它們在酸和堿中的性能不同。
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.
在堿性介質(zhì)中，純鋅的性能優(yōu)于鋁鋅合金。在酸性介質(zhì)中的性能恰好相反，熱浸鋁鋅優(yōu)于熱鍍鋅。
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，在選擇彩涂鋼板的過程中，我們建議在相對酸性的使用環(huán)境中使用鍍鋁鋅為基板的彩涂鋼板。對于相對堿性的環(huán)境，我們建議使用熱鍍鋅為基板的彩涂鋼板。
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.
