涂装估算计算

根据面积、干膜厚度、体积固体分、损耗系数和涂装道数估算涂料用量和材料费用。

涂装表面积（m²）涂装道数

每道干膜厚度（µm）体积固体分（%）损耗系数（%）

涂料单价（每升）货币

或根据截面计算面积

面积留空并选择截面、长度和数量——将使用估算涂装面积。

方法与假定

Theoretical spreading rate (m²/L) = 10 × VS / DFT ; Theoretical volume (L) = Area × coats / rate ; Practical volume (L) = Theoretical volume / (1 − loss)

VS = volume solids (%), DFT = dry film thickness per coat (µm), loss = loss factor (%)

Loss factor covers overspray, surface profile, application method and wastage (typically 20–50 % for airless spray on steelwork). Always check the paint manufacturer's product data sheet.
