Water pack sand spraying hook - — 'Gun' is a tool for the gunners

In addition to the perfect performance of particle, water sand bag also need colorful coating performance architectural color, so the metope of mature beautiful colorful coating coating. 'Gun' mobile pack sand spraying water is moving horizontally, vertically or circumferential spray coating, can not overlap, cross, or mixed. Spray gun head must be slow, level and on the wall, to ensure that the particle diffusion. 'gun' rhythm of movement of water and sediment package colorful paint decorative effect, the construction technology of water and sediment bag is the most critical part, the speed of movement of the gun is the key point. 一个。 In the process of water bag of sand spraying, if spray gun moving too fast, the water pack sand surface coating is thinner, the coating effect appears thin, not full, poor, cannot reach the effect. B if spray gun movement speed too slow, coating is too thick, lead to sagging. C, after spraying water sand gun movement speed should be fully, evenly, moist. Only have certain experience in construction personnel can achieve the effect. 'Gun' and metope, the Angle between the spraying gun and metope should try to keep the vertical or in a vertical state, because if the gun tilt, lead to the spray width deviation, water bag sand coating will flow to the side, while the other half lack of paint thinner, and even have stripe coating. Spit out particles of article can be elongated or not in the form of points, this is very ugly. The construction of 'gun' and wall distance, generally for pack sand water gun, best working distance between 40 cm to 90 cm. If the spray gun, get too close to the walls may lead to coating flow, irregular particle display surface. If the distance is more than 90 centimeters, gun pressure will be too big, too much particles will be formed in the walls of the breakpoint, easy to cause the ultra small particles or spray phenomenon, and reduces the flatness of the coating and the flow property. For the distance between the gun and guns, should also be careful analysis shows that the degree of particles, and determined the spraying distance. 'Gun' trigger on the handle control the trigger is used to control the flow of injection lance. Pull the trigger the deeper, the greater the flow velocity of sand coating water bag. As it moves, a spray gun spray gun trigger must be dead, rather than half dead. In order to avoid the paint spray gun to walk at the end of the accumulation, construction personnel should be slightly loosen the trigger, to reduce the feed rate.
