It is mainly divided into air spraying machine, high-pressure airless spraying machine, air-assisted airless spraying equipment, low-flow medium-pressure spraying equipment, airless spraying machine, high-efficiency low-pressure spraying machine and electrostatic spraying machine.

Classified by performance: plunger type, fuel type, cart type, pneumatic type. , electric, plunger diaphragm composite type. Classified according to the manufacturing principle: plunger spraying machine, plunger diaphragm composite spraying machine.

To put it simply: air spraying, airless spraying, air mixing spraying, electrostatic spraying.

There are two main types of mortar spraying machine: screw type and piston type, piston type mortar spraying machine is also called plunger type mortar spraying machine, which has its own purpose compared with screw type.

Compared with the screw type and piston type of mortar spraying machine, the rotor and rubber sleeve of the screw spraying machine are easy to wear, the replacement is troublesome, the later maintenance cost is relatively high, and the proportion of the beam of the sand is strict, the sand is slightly more easy to block the pipe, and the working distance is short; The plunger sprayer is better, it is driven by a steel crankshaft connecting rod, there are almost no wearing parts, the working distance is longer, and the work efficiency is better.

2. There are several kinds of mortar spraying machines

There are many types of spraying machines, and the mortar spraying machine is one of them, which is a special coating equipment for spraying mortar. There are two main types of mortar spraying machines commonly used:

1. Screw mortar spraying machine.

The screw spraying machine is composed of a main power motor, an air compressor, a screw, a screw sleeve, a small air tank and a pressure controller, a spray gun, a high-pressure steel wire pipe (hose), a vibrating motor vibrating screen, a controller, a body hopper and a shelf. The process of using the machine is: the main power motor starts to drive the screw to rotate, the extrusion mortar is conveyed to the nozzle, and the air compressor is started for spraying.

It is characterized by no pulse in the spraying process, relatively stable spraying, relatively labor-saving operators, mainly used for mortar spraying, putty spraying, brushing spraying, slope protection reinforcement, mortar transportation and mortar grouting within 3MPa.

2. Plunger mortar spraying machine.

The plunger type slag search spraying machine is composed of a main power motor, an air compressor, a piston, a piston cylinder, a ball head, a small air tank, a spray gun, a high-pressure steel wire pipe, a vibrating motor vibrating screen, a controller machine hopper and a shelf. The process of using the machine is: the main motor works to drive the piston to pump back and forth, the upper and lower mortar of the ball head flows into the piston cylinder, the piston cylinder pushes the mortar to the nozzle and transports it to the nozzle of the gun, and the air pump is started to spray.

In addition to these two, there is a less used, is the hydraulic mortar spraying machine, which belongs to the large spraying device, and its composition is generally composed of a secondary structure pump or a fine stone pump truck and a mobile air compressor. The spray particle size depends on the type of pump truck and the size of the air compressor. It is mainly used for large-scale slope protection reinforcement and large bungalow spraying.

It is characterized by fast spraying efficiency, and the disadvantage is that it is not easy to operate and arrange.

In our daily life, there are a lot of spray hail coatings, used in our daily necessities and various craft supplies, spray coatings are also a lot of classifications, specific different details of the classification is different, the use of natural is not the same, so, what are the classifications of spray coatings? How to apply spray paint? What are the construction steps, now I will introduce to you what are the classifications of spray paint and how to apply spray coating, to help you understand spray coating.

What are the categories of spray coatings?

According to the bulk density of the material, the classification of spray coatings is divided into light spray coatings, medium and heavy spray coatings and heavy spray materials. Lightweight spray coatings are used as thermal insulation and thermal insulation linings, medium and heavy spray materials can be used as thermal insulation linings, and heavy spray coatings are mainly used as work linings.

Spray coatings have become one of the most important amorphous refractories used in many industrial kiln linings. It can be used both in the cold state for the construction and repair of furnace linings and for coating as a protective layer, and in the hot state for repairing furnace linings.

How to apply spray paint

Spraying construction is actually the transportation, pouring or tamping into one process, without or only need a single-sided template, the process is simple, high efficiency, and has a wide range of adaptability.

According to the order of adding water (or solution) and the amount of water consumed, it is divided into three types: wet, semi-dry and dry spraying. The wet method is to mix the spraying material into a slurry and then spray, the semi-dry method is to wet the spraying material first, press it to the nozzle and then add the remaining water (or solution), and the water consumption (or solution) of the dry method is all added at the nozzle, among which the semi-dry method is the most common. Process characteristicsRefractory spray material is constructed by spraying method, and the material mix ratio, spraying operation, rebound rate and finishing process characteristics are as follows.

The mix ratio of spray coating needs to meet the following conditions: to achieve the required strength, less rebound, less spraying dust, good adhesion and not to cause blockage of the conveying pipeline. When a cement bond is used for dry or semi-dry spraying, the amount of cement used accounts for about a quarter of the total material.

If there is too much cement, the amount of dust will increase during spraying, and the shrinkage of the hardened spray coating will also increase.

Spraying operations have an important impact on ensuring the quality and rebound of the sprayed coating. Control the distance from the nozzle to the sprayed surface, usually the nozzle should be perpendicular to the sprayed surface, move according to the step-by-step rotary trajectory, and adjust the spraying wind pressure, the thickness of a spraying is subject to the spray coating does not slip or fall, but each spray coating should not be too thin so as not to increase the rebound rate.

Above, to introduce to you what are the classifications of spray coatings, the spray coatings are simply classified into light spray coatings, medium and heavy spray coatings, these three coatings are used in different places, consumers should pay attention to their needs to use in ** before buying. It also introduced how to construct the spray coating, and gave a detailed introduction to the entire construction process of the spray coating, hoping that the introduction can help you.

Types of Spraying Equipment:

1. There are three kinds of materials from the spraying materials: hardware spraying equipment, plastic spraying equipment, and wood spraying equipment. Genus.

2. From the degree of automation, it is divided into: manual spraying equipment and automatic spraying equipment.

3. From the spraying oil, it is divided into: paint spraying equipment and powder spraying equipment.

Spraying equipment has the following characteristics:

1. Satisfactory construction efficiency; The spraying efficiency is more than 300m2 h, which greatly saves manpower and man-hours.

2. Save paint; Especially for high-viscosity anticorrosive coatings, air spraying brings out the paint when the air is on the surface of the workpiece, and the utilization rate of the paint decreases. And airless spraying, can obtain a uniform coating, ** is smaller than air spraying, the effective utilization rate of the coating is high, relative to the air spraying method can save the coating 10 30.

3. Improve adhesion and prolong coating life; High-pressure airless spraying uses high-pressure jet atomization to make the paint particles obtain strong kinetic energy, and the paint particles use this kinetic energy to shoot into the void of the workpiece, thus making the coating denser, enhancing the mechanical occlusion with the workpiece, improving the adhesion, and effectively prolonging the life of the coating.

With the rapid development of modern technology and the emergence of various coating products, it is the best choice to choose the right spraying equipment for different production applications.
