无论采用哪种涂装工艺，对基板的技术要求都越来越高。大多钢基彩涂板要求平整锌花，零锌花热镀锌钢卷或电镀锌钢卷，近年有增加以热镀锌铝，等合金镀层钢板作基板的趋势；贴膜彩涂板采用冷轧卷做基板，某些高端产品还以不锈钢做基板。无论采用哪种基板，对其表面，板形及尺寸精度均有很高的要求。
No matter which coating process is used, the technical requirements of the substrate are getting higher and higher.Most steel base color coating board requires flat zinc flower, zero zinc flower hot galvanized steel roll or galvanized steel coil, in recent years have increased with hot galvanized aluminum, alloy coated steel plate as substrate trend; film color coating board with cold rolled roll as substrate, some high-grade products with stainless steel substrate.No matter which kind of substrate is used, its surface, plate shape and size accuracy have high requirements.
镀锌板的锌花结构好的镀锌板彩涂后的产品表面质量更高，更适合特殊用途。有些后加工产品对镀锌板的表面质量要求更高，需要在小锌花的基础上再进行光整处理，经光整后完全消除了锌花，这种称为光整锌花的基材，平整度非常高，涂层后的产品用途范围更加广阔。鄂钢公司冷轧薄板厂在镀锌机组配置了光整装置，生产的经光整后的无锌花镀锌板，更加适合彩涂工艺。
Galvanized plate zinc flower structure after good galvanized plate color coated product surface quality is higher, more suitable for special purposes.Some post-processing products have higher requirements for the surface quality of galvanized plate, which need to be treated on the basis of small zinc flower, which completely eliminates zinc flowers. This substrate is called the light of zinc flower, flatness is very high, and the use range of products after coating is more broad.The cold-rolled sheet factory of Esteel Company is equipped with optical finishing device in the galvanized unit. The galvanized sheet produced by light is more suitable for color coating process.
