彩涂镀锌板具有优良的着色性、耐腐蚀性、装饰性以及钢板的高强度和可加工性，深受用户欢迎。然而，在涂装过程中有时会出现爆炸性漆的情况，彩涂镀锌板爆炸性漆不仅影响板表面的美观装饰，更重要的是暴露后漆膜的直接腐蚀和非油钝化锌层的氧化。在基材上，会严重影响彩板的防腐能力，降低彩板的使用寿命。

防止 彩涂镀锌板油漆爆炸问题的发生：为保证彩涂产品在生产和运输过程中不发生质量事故，最大限度地减少产品污染和产品损坏的影响。修订了《清洁生产管理制度》和《带钢外观清洁管理办法》。对彩绘单位现场清洁生产进行每周工艺纪律检查，并通报检查情况。

及时保护和更新固化炉板温度计，用温度计纸校准温度计系数，最终确定不同色板的温度系数值，确保板温计显示温度和温度纸校准板温的温度误差为（+4 C），以便控制和指导生产。

严格按照厂家提供的钝化液凝固温度要求，确定50-80为化学镀膜板的温度检测范围。采用卷装低温测温纸进行温度测量，对有质量问题的彩色卷样采用水煮老化标记进行检测。

为保证钝化膜厚度的控制，保证镀锌板的钝化质量，提高镀层与基板的结合力。可防止彩涂钝化引起的彩涂产品爆炸性涂料质量事故。细化了彩色涂料钝化膜复验和钝化膜换辊工艺要求。每月按时沟通，控制影响彩板产品力学性能的关键涂料和钝化剂材料的目标实践值，确保彩板产品质量。

The color-coated galvanized sheet has excellent colouring, corrosion resistance, decoration, and high strength and workability of steel sheet, so it is very popular with users. However, the application process sometimes occurs explosive paint situation, color galvanized sheet explosive paint not only affects the beautiful decoration of the board surface, more importantly, the direct corrosion of paint film after exposure and the oxidation of non-oil passivated zinc layer on the substrate, will seriously affect the anti-corrosion ability of the color plate, and reduce the service life of the color plate.

Preventing the occurrence of paint explosion problem of color coated galvanized sheet: In order to ensure that no quality accidents occur in the process of production and transportation of color coated products, and to minimize the impact of product pollution and product damage, the Clean Production Management System and the Clean Management Measures for Strip Steel Appearance were revised. Weekly process discipline inspection shall be carried out for on-site clean production of color painting units, and the inspection shall be notified.

Timely protection and timely updating of the curing furnace board thermometer, calibrating the thermometer coefficient with thermometer paper, finally confirming the temperature coefficient value of different color board, ensuring that the display temperature of the board thermometer and the temperature error of the calibrated board temperature of the temperature paper are (+4 C), in order to control and guide the production.

Strictly according to the requirement of the solidification temperature of passivation solution supplied by the manufacturer, it is confirmed that the temperature of 50-80 is the scale of temperature detection for chemical coated board. The temperature is measured by low temperature temperature temperature measuring paper in rolls, and the color roll sample with quality problems is tested by water-boiling aging marking.

In order to ensure that the thickness of passivation film can be controlled, the passivation quality of galvanized sheet can be guaranteed, the adhesion between the coating film and the base plate can be improved, and the quality accident of explosive paint of color sheet products caused by passivation of color coatings can be prevented. The requirements for re-inspection of passivation film of color coatings and roll changing process of passivation coatings are refined. Communicate on time every month, control the target practice value of key coatings and passivator materials which affect the mechanical properties of color plate products, in order to ensure the quality of color coating products.
