After hemming the coat rate of interface A should be 100% and the coat rate of the interface B should not be less than 20%; if the coat rate cant meet the requirement, the diameter of the sealer should be properly adjusted.3) 密封膠的位置及尺寸要求：The location and dimension requirements of the clearance filler sealer：膠的邊緣距離涂膠所在位置兩零件重合部分的邊緣不小于5mm。通常涂膠直徑D應(yīng)比涂膠所在位置的兩零件間隙a大3-4mm。當(dāng)此膠涂在焊點處，則膠在固化后的膠接面（痕）的寬度不小于10mm。The dis
