From coated area, dry film thickness, solids content and loss rate, computes theoretical and actual coating consumption in litres or kilograms.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Spreading rate | SR = volume solids / DFT | Coatings calculation |
| Theoretical consumption | Q = area × DFT / volume solids | ISO 3233 |
| Loss factor | Actual = theoretical × (1 + loss) | Application practice |
| DFT | DFT = WFT × volume solids | ISO 2808 |
| Coverage unit | L per m² at specified DFT | Technical data sheet |
| Standard DFT | 80–200 μm per coat typical | ISO 12944-5 |
涂料用量计算器根据涂布面积、干膜厚度、固含量与损耗率,结合涂料密度,计算理论用量与实际用量(L/kg)及涂布率,辅助涂料采购与施工预算。
