What are the advantages of a mortar spraying machine?

 The mortar spraying machine is the auxiliary equipment of the construction project, which saves labor and improves the progress of the project. The mortar sprayer feeds the mixed materials from the mechanical port of the distribution mixer to the hopper of the sprayer through the vibrating screen through the screw feeding shaft. It is sent to the high-pressure chamber, and the high-pressure rotor and high-pressure stator are rotated to form high pressure. The mortar is sent to the spray gun through the high-pressure conveying pipe, and another high-pressure wind is introduced from the spray gun to blow the material away and accelerate the spray out.

The mortar spraying machine is composed of a complete set of conveying systems. There is no cavity in the system and the ability to resist negative wind pressure is strong, so it is suitable for spraying of multi-story and high-rise buildings. The cement plaster spray machine adopts soft anti-cracking technology, the elastic modulus of each layer of material is matched and gradually changed layer by layer, allowing deformation and limiting deformation combined, so it can disperse and eliminate deformation stress at any time, effectively preventing the appearance of wall cracks. Practice shows that increasing the density of the blade mortar sprayer can increase the fineness of the finished product under the condition of the same speed. That is to say, when the fineness of the finished product does not need to be changed, the high-density impeller can rotate at a slower speed than the low-density impeller, reducing airflow Resistance, the output of finished products will increase by 50% under the same power.

Precautions for spraying of mortar sprayer:

Mortar spraying equipment can be used for mixing and spraying concrete. When mixing concrete, pay attention to the mixing time and the order of feeding. Attention should be paid to spraying operations: spraying distance, spray gun operating speed, the overlap of spray patterns, and paint viscosity. Only by paying attention to these aspects can the most satisfactory spraying effect be obtained. The specific points of attention are as follows:

1. When using a large spray gun, the spraying distance should be 20~30 cm, and when using a small spray gun, the spraying distance should be 15~25 cm. If the distance is too close, the spray will be thick, and too far will be thin.

2. The running speed of the spray gun should be kept at a uniform speed, generally, the speed is 30-60 cm/sec. Too slow is easy to cause sagging, and too fast is easy to leak.

3. The overlap of spray patterns needs to accumulate experience in daily work in order to maximize the spraying effect.

4. The temperature of the sprayed paint should be controlled at 20-30°C, otherwise it will affect the viscosity of the paint and thus affect the spraying effect.
