Construction matters needing attention
1, the influence of the former treatment: surface oil or fat is not thorough, after coating may appear shrinkage, even if
The formation of a continuous film, it will seriously affect the adhesion of the film, so that the film prematurely peeling. The workpiece surface rust, acid, alkali, welding slag and other dirt, the film will appear blur, flow mark, white, granular and pitting, and the loss of light, rough, not ideal film.
The temperature of the bath 2, dipping paint: General requirements 15 to 30 DEG C, low temperature, high viscosity liquid paint, asphalt
Paint time is long, the workpiece is easy to paint.
3, the impact of tar paint: any paint, the lower end of the workpiece will appear paint phenomenon, in order to reduce this situation,
Dip after the operation, must ensure that sufficient time should drain, manual or automatic "throwing" liquid paint operation, table dry before using paint brush paint at the lower end of the fall. Due to the high heat of vaporization of water (540 * 4.18 J/g), it is slow to slow the rate of evaporation, paint time is generally from 10 to 15 min. In addition, the ambient temperature should not be lower than 15 DEG C in the process of painting, with a temperature of between 25 and 35 DEG C, and the relative humidity should not be greater than 75%.
4, in order to prevent pigment precipitation and liquid crust, must be continuous mixing. Proper mixing can ensure the paint solution
Uniformity of the parts to ensure smooth film. And there must be filtering equipment, the paint liquid particles out of the filter can play a role in defoaming.
5, when the relative humidity in the summer more than 75%, the paint room to deal with dehumidification, otherwise, it will affect the appearance of the film, dry and other properties.
6, this product by dip coating, the coated pieces hanging upside down for a good, to prevent the fat edges; to accelerate drying, drain after 50 ~ 80 DEG C dried 30 ~ 60min.
Storage period
Sealed in 5 to 35 degrees, cool and dry place, for 6 months.
