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。
结果
理论涂布率8.00m²/L
理论涂料用量1.01L
估算涂料消耗量1.45L
涂装材料费用0.00AUD
每道湿膜厚度125µm
总干膜厚度75µm
扣除损耗后的实际涂布率:5.60 m²/L。
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.
