    辊涂是UV涂料应用最广泛的一种施工方式,通过辊涂设备将UV涂料涂布到工件上,再通过紫外光进行固化的连续作业方式。



1.前面样板造成的的不均匀  


原因:涂布辊没有再变湿润达到前面样板的同样水平


解决方案:用刮刀刮涂布辊


 

2.出现横线 


原因:


传送带和涂布辊不同的速度

涂布辊坏了;涂布辊压力太大

涂布辊和定量辊的压力太大

定量辊反转的速度太快

当定量辊反向运行的时候,辊子之间的油漆不够

辊子或传送带的轴承坏了   


解决方案:


检查涂布辊和传送带速度(辊子必须要干净)

查看涂布辊上是否有损坏

使用较小压力

释放辊子间的压力 

减速回动定量辊

提高泵的压力

更换轴承



3.出现纵线
