1. When the temperature is below 5 ° C or above 40 ° C, measures must be taken to improve the climatic conditions to an acceptable range.
2. If the relative humidity exceeds 85% or the steel plate temperature is below 3 °C of the dew point, do not perform final sandblasting or painting.
3. When it rains and snows, there is water on the surface, or fog, it is impossible to paint.
4. The measurement of dry film thickness is performed according to two 80%, that is, 80% of the measurement points should reach the specified dry film thickness, and the remaining 20% ​​of the measurement points should reach 80% of the specified film thickness. Dry film thickness inspection was performed in accordance with ISO 2808 and SSPC PA2.
5. Sandblasting and painting must be carried out in the factory and cannot be carried out at the same time. Since the painting workshop is next to the sandblasting workshop, the dust is easily scattered and settled on the newly painted surface. Therefore, the drying degree of the paint film must be checked according to the relevant product specifications before the sandblasting starts to avoid dust pollution.
