High-pressure airless spraying machine and screw spraying machine have different structure and performance. The requirements for building materials are more different. For each area, the complex materials and formulas are different, so the sprayer should be carefully selected.
1. High pressure airless spraying machine
High pressure airless spraying machine,In today's construction environment,It is accepted by more and more people.
Friends who use high pressure airless spraying machine know that
It can mainly spray some building materials without particles.
For example: putty powder, latex paint, paint,White cement, black cement, waterproof coatings, etc.
Most of the current construction masters use it to spray putty powder.
Therefore, we also call large-scale high-pressure airless spraying machine as putty spraying machine.
2. How does the high pressure airless spraying machine work?
Large high pressure airless spraying machine are generally hydraulic ram type, which uses a hydraulic pump to directly apply material to a pressure of more than 200 bar. When the high-pressure material is sprayed through the nozzle of the spray gun, the pressure difference is relatively large, and the high-pressure material is instantaneously atomized into many fine particles hitting the wall surface. As the material is continuously ejected, the misty material particles are present. The walls are tightly packed together, and the spray gun moves at a constant speed. In this way, the misty material forms a uniform coating on the wall.
In order to spray better, when spraying on a flat wall, the speed of the gun should be as uniform as possible, and the place where the pit is uneven, the speed to the pit is slightly slower, and the gun in the high place is slightly faster. This can be set off a little, and the effect of the spray will be better. Of course, the best way is to deal with the uneven place in advance, this is the correct construction step.
3. Screw spraying machine
Screw spraying machine， We also call it a multi-function spraying machine. Why is it called a multi-function spraying machine? Because it can spray a wide range of building materials, basically material particles below 6mm can be sprayed, such as: plaster, cracking mortar, real stone paint, cement mortar, thick fire retardant coating, thin fire retardant coating and so on.
Someone may ask me: "I buy a screw-type spraying machine, not all materials can be sprayed, putty powder can also be sprayed?" Theoretically it is ok, but the actual effect is not satisfactory. For example, what kind of material can be sprayed on a machine, but the actual effect can not meet the construction requirements or can not be sprayed out, which is also useless. Just like the spraying machine that can be sprayed on the building materials at the beginning , the spraying machine can only complement each other and cannot be replaced, and each has its own place.
4. Working principle of screw spraying machine and high pressure airless spraying machine
The screw spraying machine mainly sends the material to the tip of the gun and the compressed air to form atomization by the principle of spiral extrusion. The high-pressure airless spraying machine mainly forms atomization by its own high pressure principle. They are all pumps that allow the materials to quickly get on the wall, assist people in construction, and reduce the heavy work of people.
As the times progress, there will be more and more machinery that assists people in construction. You may be questioning and embarrassing now, but when more and more people around you start accepting and using machinery to make money, you don't miss out on opportunities to make money. Opportunities are always caught by those who are prepared.
