The roller water nozzle is mainly used for road cleaning and dust reduction operations: by flushing the road surface with high-pressure water flow, it can effectively remove dirt, stones and other debris, reduce dust during operation; at the same time, it can regulate the road surface temperature, avoid road surface plasticization in high temperature environment, and reduce the viscosity of mold tape. The water nozzles sold by our company are divided into two categories: the direct spray nozzle adopts a vertical downward water flow design to form a concentrated water column, which is suitable for areas that require high-intensity local wetting; the oblique spray nozzle sprays water at an angle of 15°- 45°, and the water flow spreads in a fan shape, covering a wider area, and can achieve uniform wetting of a larger area.
