Calculation of air volume conforming with safety and hygiene standard 卫生通风计算
1 i4 S* D! m3 EThe minimum air volume per minute for 1 kg of consumption of paint or thinner is given in the product technical data sheet. During practical application and drying, the air volume conforming to TLV can be calculated by the following equation:

Example, if t is 30 min., P is 50kg, Q is 4kg, Q is 2kg, M is 800m3 (shown in the product technical data sheet) and N is 2200m3 (shown in the product technical data sheet), the air volume conforming to TLV can be calculated by the following equation:4 |0 p$ V' p3 `
计算举例 在30min.时间内(t),用于50kg油漆(P)和2kg用于稀释油漆的稀释剂(Q),M值为800m3(从产品技术资料中查得),N值为2200m3(从产品技术资料中查得),则施工中要达到TLV所需的实际通风量为:3 E& |8 h6 k: p0 J0 R( o8 z6 [
