    卡车白车身表面积多大?

        前几天,有人问我,一台白车身需要多少电泳漆。我想白车身表面积乘以漆膜厚度就行了,我不知道电泳漆膜厚度是多少,应该查一下工艺卡就行了。
        白车身表面积的精确方法就是,把每一个部件的表面积都用三维软件测量出来,然后简单相加就可以了。另外一种就是估算,一般卡车白车身是一个类似于正方体的剥壳。比如说整体尺寸是2.5m,那么外表面积就是2.5*2.5*6,加上内表面积就是2.5*2.5*6*2。另外,白车身不止有外板,内部还有许多加强梁,根据加强梁的多少,应该乘以一定的系数,一般是1.2. 
        所以卡车白车身表面积就是:边长*边长*6*2*1.2
