lost light |
① humidity environment at the scene, more than 90%, water vapor condensation on the film surface.
② the scene temperature is too low, slow drying, water-surface in a stolen light.
③ Tu of the surface was too rough, the absorption of the paint, coating too thin.
④ film too thin, excessive amount of thinner.
⑤ yet to dry on the bottom under a layer of Tu.
⑥ Tu of the surface was damp or acid, salt, alkali and other material
⑦ paint thinner and in the mixed with water.
⑧ air compressor in the water did not remove the net. |
① adjust the indoor humidity or stop the construction.
② construction in the general ambient temperature above 10 ℃.
③ attention to the size polished sandpaper to ensure that the Tu-surface formation.
④ The proportion of added diluent, and to increase the number of film.
⑤ in the film to be under a layer of dry before construction.
⑥ handle the Tu-surface impurities.
⑦ properly manage paint, to prevent mixing with water.
⑧ clear air compressor gas in the water, oil-water separation and maintenance. |
