The high-pressure airless paint sprayer is a spraying technology that does not require air. Make the paint adhere to the object to be coated at high speed. The application of high pressure airless spraying machine in the construction of latex paint walls has many obvious benefits: 1. Improve the coating quality. Airless spraying can not only atomize high-viscosity paint, but also the surface of latex paint applied by airless spraying is smooth and dense, without brush marks and rolling marks. 2. Speed ​​up construction. The construction efficiency of airless spray machine is as high as 300 square meters per hour, which is 12 to 15 times that of the traditional rolling brush process! 3. Increase paint utilization. Due to the uneven thickness of the paint film in the traditional roller brushing method, the usage rate of the paint is greatly reduced, while the airless spraying can ensure that the paint film is uniform and the thickness is consistent. 4. Extend paint life. When the paint adheres to the surface of the coated object under high speed and high pressure, it will form a mechanical bite force, so that the paint particles can penetrate deeper into the pores of the wall, enhance the adhesion of the paint film, and prolong the life of the paint film. In the early days, high-pressure airless sprayers were widely used in the spraying of industrial projects such as shipbuilding, steel structures, and heavy anti-corrosion. With the continuous development of the construction industry, airless spraying technology has also been gradually applied to the spraying of construction-related projects, and has been popularized in Europe, America, Southeast Asia and Taiwan. Since high-quality latex paint with a high unit price has been used, if you want to obtain the same high-quality wall effect, using a high-pressure airless sprayer is an inevitable choice.

High pressure airless paint sprayers use a high-pressure plunger pump to pressurize the paint to 3000 PSI (210 kg/cm). The paint is delivered to the spray gun through a high-pressure hose, and the pressure is released through the nozzle to form atomization that creates a dense coating on the surface of the wall. Since no compressed air is required to atomize the paint, it is called airless spraying. 1. Before using this high-pressure airless spray machine, please make sure to read carefully and strictly comply with the requirements of this instruction manual. 2. The high-pressure airless sprayer must be placed smoothly and securely during the operation.

If the high-pressure tube is replaced, the tube selected must be uniformly equipped by the paint sprayer manufacturer. 8. At no time is not allowed to point the gun at others, when operating to prevent the splash of paint on the operator's body, especially eye injury. 9. Don’t allow use the high-pressure airless sprayer spray acid, corrosive substances, toxic chemicals (such as pesticides, pesticides, etc.). Do not use banana water, dimethyl dumb and other solvents for spraying operations.during the operation, the operator should not eat food, do not smoke. 10. After the completion of the spraying operation, to unload the flow, unload the pressure, and then turn off the motor, and then immediately clean the parts of the paint flow through the cleaning solution, wash the residue, it is strictly prohibited to clean with boiling water. 11. When moving the airless sprayer, generally cut off the power supply, motor and plug are not allowed to contact with water and paint, keep the machine clean and dry. 12. The tools used in any fastening, adjustment and maintenance of this airless sprayer should be suitable and the operation should be standardized to prevent damage to the machine or the person. 13. Do not allow arbitrary changes to the structure of this airless sprayer. Do not use spare parts that do not meet the requirements.

Airless spray machine spraying material composition materials mainly to anti-corrosion and fire protection materials, epoxy resin, or latex paint, in the choice of airless spray tips we have to think of the two aspects of the problem, one is the spray width, the other is the flow is also the size of the caliber. Paint sprayer nozzles are generally divided into three types, respectively standard, finishing and wear-resistant, expressed in English symbols are LTX (standard), FFT (finishing), GHD (wear-resistant), the number of the code is the introduction of the spray width and calibre data. In accordance with their true wishes, consumers can choose the model you want to buy, and only through this method can they be assured that it is exactly what they need in reality. Here are some of the things we need to be aware of when buying a sprayer nozzle When using airless paint sprayer to spray fireproof and anti-corrosive materials, we need to use a standard type of nozzle. As the granular material contained in these sprayed materials is a serious wear and tear on the nozzle, it is still recommended here that you use a wear-resistant nozzle. When spraying anti-corrosion materials, we need to consider the problem that the thickness of the anti-corrosion material sprayed is relatively heavy, it is best to use a larger diameter nozzle when choosing airless spray nozzle, but for steel construction of anti-corrosion materials, it is best to use a nozzle with a spray radius of 5 inches or less, which will reduce the waste of paint and improve the use of paint. When the paint sprayer is used to spray emulsion paint, in order to ensure the efficiency of the construction and the thickness of the emulsion paint, it is best to use a standard type nozzle with a spray radius of five inches and a calibre of 0.0017 inches as the best option. When spraying the corners of the walls, it is necessary to switch to a nozzle with a relatively small spray width. When painting external walls, we can use a nozzle with a spray radius of twelve inches, which will increase efficiency. However, due to the larger spray range, it is best to choose a larger spraying machine to ensure a uniform thickness in order to ensure the quality of the spraying. When paint spraying machine spraying oil-based paint, we need to pay attention to the characteristics of the paint, oil-based paint density is low, strong liquidity, when the spray width is large, easy to cause the paint hanging, it is best to use the finishing type of nozzle, this type of nozzle atomisation effect is better, can be more liquid paint spraying more evenly, in reducing the wear and tear on the nozzle at the same time to extend the use of the nozzle time. The above describes so much about the use of spraying machine nozzle, the first contact with this equipment, many people will be confused, do not know what this machine is for, more do not know how to choose when using, in fact, this equipment looks huge, extremely complex, in fact, the working principle is still relatively simple, the general personnel after a simple training, can be skilled operation, save time and effort, the above I believe that you should have a certain understanding of this equipment, I hope that these introductions can produce a certain amount of help to the practical use of everyone.

When purchasing liquid spray equipment, it is critical to choose the technology that is best for your application. Since there are many factors to consider, it helps to understand the differences between air spray machine, airless spray machine, or air-assisted airless spray technologies. Air spraying uses a low-pressure fluid stream mixed with compressed air at the air cap to atomize the material in a controlled manner. It is used for applications with low to medium viscosity fluids for products requiring high quality, Class A or decorative finishes. Airless spraying machine uses a high-pressure fluid supply for atomization without the use of compressed air. It is used for medium to high viscosity fluids, provides lower surface quality, and contributes to speed and transfer efficiency. Airless spray atomization is created by fluid pressure pushing the material through the orifice. As the fluid flows out, friction between the fluid stream and the atmosphere breaks down into small particles. The airless spray tip size and pressure determine the flow rate. High pressure paint sprayer creates a complete pattern - the higher the viscosity of the material, the higher the pressure required. Each spraying technique has advantages and disadvantages. Air spraying is best for products requiring a high quality finish, but is not as efficient in transfer. Airless has higher transfer efficiency and is typically used for protective rather than decorative coatings. Air Assisted Airless offers high production levels and high quality finishes. To determine the best technology for your application, identify your spray requirements.
