| 喷嘴出料口与被涂物之间的距离称为枪距。枪距越小，喷涂压力就越大，产品受到气压的冲击也越大，涂层就会出现不平均的情况，产生涂膜过厚的问题。枪距越大，喷涂压力越小，涂料易流失，使被涂物部分喷料过少，涂膜达不到指定的厚度。喷涂扇面与被涂物面呈现垂直的状态。手工操纵喷枪时，喷涂宽度不能出现过大的情况，否则会出现涂层平均的问题。喷枪运转的目的要始终与被涂物面平行，与喷涂扇面垂直，运转速率不稳，涂层厚度不平均，运转速率过快涂层太薄，运转速率过慢涂层太厚。总而言之，在使用喷涂设备的时候，要做到力度适中，距离合适才可以，这样才能够得到想要的涂装效果，在施工后，一些扫尾的事情也需要完善起来，涂料及帮助器具的收拾，使用后的残剩涂料要封锁保留，这都是需要注意的问题。 The distance between the nozzle outlet and the coating is called the gun pitch. The smaller the gun distance is, the greater the spraying pressure is, and the greater the impact of the pressure on the product, the uneven coating will appear, resulting in excessive coating. The greater the distance between guns, the smaller the spraying pressure, paint easy to lose, so that the coating part of spraying too little, the coating can not reach the specified thickness. Spray fan and the coated surface presents a vertical state. When spraying the gun manually, the spraying width can not be too large, or the average coating will appear. The gun running to always be parallel with the surface coating, spray fan vertical, speed instability, coating thickness is the average speed is too fast, the coating is too thin, too thick coating speed is too slow. In short, when using the spraying equipment, to achieve moderate intensity, proper distance can, so that we can get to the coating effect, after construction, some outstanding things will need to be perfected, and help clean up paint equipment, after the use of the remaining paint to block retained, it is need to pay attention to the problem. 喷涂作业需要注意的事项包括：喷涂移动速度、扳机的控制、枪距还有握枪姿势等等。 The matters needing attention in spraying process include spraying speed, trigger control, gun distance, holding gun position and so on. 一、喷涂移动速度。在喷涂作业时，喷枪的移动速度对涂装效果有很大影响。 I. spraying speed. During the spraying process, the moving speed of the spray gun has a great influence on the coating effect. 1、如果手工喷枪移动太快，被涂物表面涂层稀薄，显得干瘦、流平性差、粗拙； 1, if manual spray gun moving too fast, the surface coating material is thin, thin, leveling, coarse; 2、如果手工喷枪移动速度慢，被涂物表面涂膜肯定很后，而且易产生流挂现象。 2, if the manual spray gun moving speed is slow, the coating surface coating must be very after, and easy to produce flow hanging phenomenon. 3、理想的喷枪移动速度是喷涂结束后，被涂物表面涂层饱满、均匀、润湿。这个需要有一定喷涂经验的作业人员才能控制。 3, the ideal spray gun moving speed is the end of spraying, the coating surface coating plump, even, wet. This requires a certain spraying experience of the operator to control. 二、对扳机的控制。喷枪是靠扳机来控制的。扳机扣得越深，液体流速越大。静电喷涂设备在传统走枪的过程中，扳机老是扣死，而不是半扣。为了避免每次走枪行将结束时所喷出的涂料堆积，有经验的喷漆工都要略略放松一点扳机，以减少供漆量。 Two, control of the trigger. The spray gun is controlled by a trigger. The deeper the trigger, the greater the velocity of the liquid. Electrostatic spraying equipment, in the process of traditional gun, the trigger always buckle, rather than half button. In order to avoid the accumulation of every walk at the end of the spray gun spray coating, experienced to slightly relax the trigger, to reduce the amount of paint for. 三、喷枪对基材表面的方位。喷枪对基材表面应该保持垂直，或者尽量保持垂直。假如喷枪有一点歪斜，其结果必定会造成喷幅带偏向一边流淌，而另一边则显得干瘦、缺漆，极有可能造成条纹状涂层。 Three. The orientation of the spray gun on the substrate surface. The spray gun should be vertical to the base surface or as vertical as possible. If the gun has a little askew, the result will cause the spray range with side flow, while the other side is thin, lack of paint, most likely caused by stripe coating. 四、喷枪至基材表面的间隔。对虹吸式喷枪而言，最佳工作间隔为15~20cm。假如间隔太近，则可能产生流淌，在喷金属闪光漆或珠光漆时甚至可能造成颜色与预期的不一致。假如间隔太远。超过20cm，则可能导致干喷、过喷，使涂料的流平性变差。假如喷涂的金属闪光漆，也可能存在颜色改变的可能性。压送式喷枪可以离基材远一些。一般最佳间隔在20到30cm。这些都是喷涂施工时必需遵循的原则。 Four, spray gun to the surface of the substrate interval. For a lance, the optimum working interval is 15~20cm. If the interval is too close, it may produce a flow, and may even cause the color to be inconsistent with the expectation when spraying metallic flash paint or pearlescent paint. If the gap is too far away. More than 20cm, may lead to dry spray, over spray, so that the poor leveling of paint. The possibility of color change may also exist if sprayed metal flash paint. The press gun can be a little farther from the base material. The best interval is between 20 and 30cm. These are the principles that must be followed in the construction of the spraying. 五、握枪。喷枪是靠手掌、拇指、小指以及无名指握住的，中指和食指来扣动扳机。有些喷漆工在较长时间工作时，时不时改换握枪的方式，有时仅仅用拇指，手掌配合小指，有时又是配合无名指握枪，中指和食指用来扣扳机。静电喷涂设备这样可以缓解疲惫，提高工作效率。 Five, hold a gun. The spray gun is held by the palm, thumb, pinky finger and ring finger, and the middle finger and index finger pull the trigger. Some painters change their grip from time to time, sometimes using only the thumb and palm with the little finger, and sometimes with the ring finger. The middle finger and the index finger are used to pull the trigger. Electrostatic spraying equipment can relieve fatigue and improve work efficiency. |
