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.

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.

The cleaning and maintenance methods and steps of airless paint sprayers: 1. After the spraying operation is over, the airless sprayer should be cleaned immediately to remove the residual paint in various parts where the paint flows to prevent it from hardening and causing blockage. When cleaning, just replace the paint with the corresponding solvent and spray according to the operation, until all the paint in the body, high-pressure pipe and spray gun is sprayed out. 2. After using the airless paint sprayer for a period of time, it is necessary to clean the filter screen of the spray gun. The method is: remove the movable joint and the buckle, unscrew the handle of the airless spray gun, take out the filter element in the handle and clean it, and then put it back in order, Tighten. If the filter element is found to be damaged during cleaning, it should be replaced with a new airless sprayer filter element. 3. If the spraying is not smooth during the spraying process, check and clean the suction filter in time. Generally, the airless suction filter should be cleaned after each shift. 4. Regularly check whether the fasteners are loose and whether the seals are leaking. 5. Under normal circumstances, after three months of continuous use of the airless sprayer machine, open the pump cover to check whether the hydraulic oil is clean and lacking. If the hydraulic oil is clean but missing, add it; if the hydraulic oil is not clean, replace it. When replacing the hydraulic oil, first clean the oil cavity of the pump body with kerosene, and then add hydraulic oil with a volume of about 85% of the oil cavity, which is equivalent to about 10mm between the oil surface and the top of the pump body. 5. If you still need to use it the next day after each use, please do not drain the liquid in the suction pipe, body and high pressure hose pipe, or do any disassembly, just soak the suction pipe and discharge pipe spray gun in the It can be stored in the corresponding solvent; if it needs to be stored for a long time, the liquid in the machine should be drained, and it should be packaged and stored according to the new paint machine state.

What is airless paint spraying? Simply put, airless paint spraying simply uses material pressure without air. An electric or pneumatic pump or gasoline engine puts the material under pressure and forces a specified amount of material through the tip hole at a maximum pressure of 250 bar. This converts the material into a spray. Use the pump to bring the paint material to a pressure of up to 250 bar and then pass it through the airless spray gun. When the airless paint valve (gun) is opened, the paint is forced through the opening in the airless nozzle of the required size. Atomization is created by the pressure difference between the coating material and the atmosphere. The flow rate and spray width are determined by the airless spray tip. Various materials can be sprayed with airless paint sprayers. We have summarized them here: Water-based and solvent-based paints, varnishes, lacquers, oils, separators Synthetic resin-based coatings, PVC coatings, 2-K lacquers Primers, fillers Fireproof coatings, anti-corrosion coatings Emulsions, emulsion paints, adhesives, sealants Masonry coatings, roofing coatings, flooring coatings, silicone coatings Fillers and other high viscosity materials
