粉末涂料取代传统溶剂型涂料，革新了传统彩涂板的生产方式，大大缩短了工艺流程，产品性能更优异。固化段只有一次烘烤，可大大降低能耗30%以上，且无溶剂挥发，VOC零排放，真正做到了绿色环保，优化了生产环境。
5)内气胜，层表，需要机洗6)冷过
(3)高速涂层时出现点状式的“失膜”:
1)PMT 控制不当引起涂层“失膜”，这时要及时调整炉温;
2)辊速比不四配，这时要及时调整辊速比;工,更講外其于由样的 :著
3)涂敷辊存在缺陷，这时要及时更换完好涂装辊;
4)涂料黏度不当引起涂层“失膜”，这时要及时调整涂料黏度。”,樂润定
(4)高速或低速涂层时出现线状“失膜”“验领族大成南厨前间微直和常钟用1)辊速比不匹配，这时要及时调整辊速比;
2)涂敷辊存在缺陷，这时要及时更换完好涂敷辊。(5)钢带两边缘涂层厚度不一样:-齐回只
原因是涂敷辊与粘料辊之间辊缝两端不均匀，这时只有停机调整两端辊缝平衡。意(6)湿涂层表面发现横向条纹即“抬头纹”
1)基板镀锌层横向条纹带来引起的;
(1) Color difference:
1) There is a large color difference in the coating itself. Thetype of coating should be changed immediately;
2) Improper control of film thickness causes color difference ofcoating. Adjust the film thickness in time to eliminate the colordifference;
3) The coating color difference is caused by improper PMT control.To adjust the furnace temperature in time, it should be adjustedand controlled according to the PMT adjustment range provided bythe coating manufacturer as far as possible
4) Improper control of baking time and air speed in the furnacewill also cause color difference of coating. It is necessary totimely adjust the production process speed and adjust the balanceof air flow in and out of the furnace.
(2) Hard block or pockmarked spot: come to the small and big sandscreen to find out the wealth
1) If the substrate is rough or defective, the substrate must bereplaced;
2) Before coating, if the coating is polluted and the coatingsurface is affected, the coating or filter coating shall bereplaced in time;
3) 4) too heavy acid gas in the furnace causes the coating toharden, so the furnace temperature should be adjusted intime
5) The inner gas is better than the outer layer. It needs machinewashing. 6) supercooling
(3) In high speed coating, there is a point like "filmloss":
1) If the coating "loses film" due to improper PMT control, thefurnace temperature should be adjusted in time;
2) Roll speed ratio is not four match, then it is necessary toadjust the roll speed ratio in time; work, more importantly, itdepends on the type: work
3) If the coating roller has defects, it should be replaced intime;
4) Improper viscosity of coating will cause coating "loss of film".At this time, the viscosity of coating should be adjusted in time ,lerunding
(4) When coating at high speed or low speed, linear "film loss"occurs. 1) the roll speed ratio does not match between the frontroom of
