Water-based fluorocarbon paint is a kind of industrial heavy-duty anti-corrosion products, construction requirements than oil paint a lot of strict, not only to ensure that the primer was painted without oil ash and other dirt, Completely dry, and the other surface can not be damaged, today Xiaobian a comprehensive introduction to the specific requirements of the construction of the paint and high temperature weather construction needs attention. Water-based fluorocarbon paint before the basic requirements:
1, the construction conditions Ambient temperature: 5-40 ℃ relative humidity: 80% of the following Note: not less than 3 ℃ and ambient humidity greater than 80% under the conditions of painting, painted film within 4 hours after the rain can not rain , More can not be washed with water. 2, the construction method using brush, spray, no air spray, dip coating, but the spray pressure should be 0.25-0.5Mpa range, high pressure airless spray, nozzle pressure should be controlled in the 12-15Mpa range.
3, the coating tool using brushing process, should use soft brush, hair length 5cm is superb, the use of spray nozzle diameter should be 0.4-0.6mm appropriate, the use of high pressure airless spray, gun nozzle diameter should be 0.4-1.3mm range Good quality. In the construction process, must use the painting tool alone, not with other paint or equipment mix, with the tap water after cleaning, for repeated use.
4, stirring dilution should be fully mixed lacquer slurry, in case of viscosity is too large, may be appropriate to add tap water dilution, adjust the viscosity of 20-40S (coated -4 cups), dilution of the paint must be used within 30 days.
5, overcoating time normal ambient temperature and environmental humidity, (temperature 23 ℃ ± 2 ℃, humidity 50% ± 5), 12 hours after brushing two coating. In case of ambient temperature and environmental humidity changes, the corresponding extension and shorten the drying time, the same will also extend or advance the construction of two coating. When the coating on the hot surface of the hot surface of the coating, due to the curing speed, resulting in the coating can not be fully fused, leveling poor, resulting in porous coating, hot surface brushing, will cause uneven coating, Leaving a clear brush mark. For these reasons, when the temperature is higher than 30 ℃, Fluorocarbon paint http://www.senta7.com/ effect is not ideal, so in the summer sun exposure of steel surface should not paint. In addition, in the high temperature of the sealed chamber spray, due to the rapid evaporation of solvents and thinner, in a short time will produce a high gas concentration, therefore, pay special attention to the use of reasonable and effective ventilation, To avoid the risk of explosion.
