How to correctly choose the nozzle of a spraying machine
The main components of spraying materials are anti-corrosion and fire-proof materials, epoxy resin or latex paint. When selecting a sprayer nozzle, we need to consider these two issues, one is the spray width, and the other is the size of the flow diameter. So how to correctly choose the nozzle of the sprayer?
1. When the sprayer is used to spray latex paint, in order to ensure structural efficiency and the thickness of the latex paint, we recommend using a standard nozzle with a nozzle radius of 5 inches and a diameter of 0.0017 inches. At the corner of the spray wall, it is necessary to switch to a nozzle with a relatively small spray width. When spraying exterior walls, we can use a nozzle with a spray radius of 12 inches, which can improve work efficiency. However, as the spray range becomes larger, in order to ensure spray quality, we prefer to use larger spray equipment to ensure uniform thickness.
Second, when the sprayer sprays oily paint, we need to pay attention to the characteristics of the paint. Oil-based paint has low density and strong fluidity. When the spray width is large, it is easy for the paint to sag. At this time, we should use the finishing nozzle. This type of nozzle has better atomization effect, can spray smoother coating more evenly, reduce the wear time of the nozzle, and reduce the wear time of the nozzle at the same time.
Third, when using a spraying machine to spray fireproof and anticorrosive materials, we need to use standard nozzles. Since the particulate matter contained in these spray materials is more severe on the nozzle, it is recommended to use a wear-resistant nozzle here. When spraying anti-corrosion materials, the thickness of the anti-corrosion materials should be considered. When choosing a nozzle, it is best to use a nozzle with a larger diameter. However, for anti-corrosion materials for steel structures, the spray radius is used. The nozzle is less than 5 inches, which can reduce the waste of paint and improve the usage rate of paint.
