Really stone paint spraying seven skills, build perfect metope

In recent years, water-based paint is developing very quickly. Now most of the outer wall is mainly composed of water-based coatings such as true stone lacquer is made, because really stone paint construction is convenient, can greatly save the cost. Really stone paint spraying technology is used in the construction? Next, fujian KeBao will give you details. A, nozzle and the distance to a 300 - commonly It is advisable to 400 mm. It is easy to hang too close; Distance too far uneven paint mist, prone to pitting, nozzle away from the surface, paint mist scattered on the road, causing waste. From the specific size should be according to the coating type, viscosity and pressure to adjust. Slow dry spray distance can further, quick drying coating can be closer; When the viscosity is bigger, can be closer; When the viscosity is small, can further. When high pressure, the distance can be further, when air pressure is low, can be closer. The so-called 'closer and farther' refers to the adjustment between 10 mm and 50 mm. If beyond this range, will get no satisfactory paint film. On to the next second, spraying down a third or a quarter, so as not to appear leakage phenomenon. When spraying, fast-drying paint, should be a complete in turn. Supplementary spray effect is not ideal. Third, gun can make up and down, left and right sides is mobile, better to 10 - 12 m/min speed uniform operation, spray nozzle to be flat on the surface, to minimize the oblique spraying. Both ends of the coating surface should loosen hand pull the gun trigger quickly, in order to reduce oil mist, because often need to spray more than two surfaces at both ends and this is the place where easy to droop. Four, the empty place outdoors when spraying, attention should be paid to the direction of the wind, When the wind is unfavorable operation) , the operator must stand in the wind, prevent mist was blown to the unattractive granular spray has a good film on the surface. Five, with clean water spray paint to fit on viscosity, coating - 4 viscometer measurement, suitable viscosity are generally 20 to 30 seconds. If there was a time not viscometer, can use the visual inspection method: (with a stick Iron bars or rods) Will paint mixing evenly, then improve it to a height of 20 cm to stop watch. If the paint in a short period of time ( A few seconds) There is no continuous flow, it is too thick. If line left the barrel of the upper edge of the broken, it is too thin. When the paint stay at an altitude of 20 centimeters, the paint will be in a straight line, and immediately stop into droplets. The viscosity is more suitable. Six, good control the air pressure at 0. 3 - 0. Palmer (4 million 3 - 4 kg/cm2) 。 Pressure is too low, paint liquid atomization is bad, the surface will form pitting; Pressure is too large to sag, which not only cause too much paint mist, and waste material, affect the health of the operator. The order of the seven, spraying is: difficult before they are easy, after the first. After the first high low, after the first small is big. Spray paint mist, however, could not have splashed spray coating and damage the spray paint film. The really stone paint construction of spraying technique is very important. In really stone paint construction process, attention should be strict, because good construction is essential for a good really stone paint project!
