① low viscosity of paint, spraying too many one-time, a thick coating.
② spraying, improper operation angle and distance, or spray gun speed too slow, uneven paint coating.
③ spraying air pressure imbalance.
④ paint added over the slow-dry, resulting in a coating干过slow.
⑤ Lance calibre too large.
⑥ paint containing high density of the paint, uneven mixing.
⑦ Tu of the surface was too smooth.
⑧ scene too high relative humidity, temperature too low, resulting in a slow-drying paint, paint flow too much. |
① deployment of a good paint viscosity, a coating thickness should not exceed 30 um.
② correct operating practices, operating everything goes according to standard practice, and the spray gun control appropriate speed.
③ add compressed air storage devices, construction of the air pressure remained stable.
④ season under climate change, choose the appropriate thinner. And control the deployment of proportion and drying rate.
⑤ accordance with the actual conditions suitable choice of the calibre of Lance, is generally 1.5-2 mm.
⑥ construction of paint to fully stirring several times.
⑦ ensure that the Tu-surface roughness appropriate, between each floor should be carefully polished.
⑧ control operations at the relative humidity, add mandatory drying devices, shortening the drying time, reduce the seasonal impact of climate on the intensity of the operations. |
