Causes of spray gun clogging in putty powder
The spraying effect of the putty powder spraying machine is good, and the efficiency is also very high, which can save time cost and human, material and financial costs. So now more and more large and medium-sized engineering construction and small and medium-sized home decoration have begun to use putty powder spraying machine for construction. However, when the putty powder spraying machine is in use, the spray gun may become clogged. So what are the reasons for this phenomenon? The following editors will introduce it to everyone.
First, the choice of nozzle diameter is not suitable for many specifications of putty powder spraying machines, small putty powder spraying machines, medium and large putty powder spraying machines, etc., their power is also different, some are 3KW, some are about 5KW, and 7KW Left and right, and the nozzles of these putty powder spraying machines with different specifications are also different in size. If the power is high but a small nozzle is equipped, it is easy to block the gun.
2. The putty does not mix well, because it contains particulate impurities. Because the putty powder sprayer is a high-pressure airless sprayer, the spraying principle is that after the putty is subjected to high-pressure treatment, it is atomized by the nozzle and sprayed onto the wall. The nozzle is relatively small. Therefore, it is necessary to ensure that the putty must be uniformly blended, and must not contain particulate impurities such as sand and fiber, otherwise these particulate impurities will block the nozzle of the gun and cause the spray gun to become blocked.
3. Putty is too viscous and pressure is insufficient. Putty powder spraying machine is high-pressure spraying. If the putty is too viscous, it has less water. During the atomization process, a part of the water will be lost, which will cause the sticky putty It dries quickly, and the putty after drying out can easily block the mouth of the gun, especially when the pressure is insufficient, the probability of blocking the gun is higher.
The above is the cause of the clogging of the spray gun of the putty powder spraying machine. I hope it can help everyone. If you have any other questions about this, please feel free to contact us!
