Sprayer nozzle material
The material of the sprayer nozzles are generally copper, nylon, stainless steel, corundum, porcelain, ceramics, and so on. The material of the sprayer nozzle determines the nozzle life, generally copper nozzle using life of 100 hours, the nylon 200 hours, 300 hours of corundum ceramic, stainless steel, ceramic, polymeric materials of 400 hours. (This not used on mini fogger.)
The life of sprayer nozzle depends on the material of the nozzle, the physicochemical properties of the drug solution, spray pressure, dosage form, etc. a variety of factors. Nozzle wear and damage will cause the flow rate, spray angle, droplet size should change. The sprayer nozzles quality is mainly reflected in the orifice size precision, material and finish, flow, spray pattern, droplet size and distribution uniformity the material determines life; good finish to reduce congestion; spray hole size precision decided key factor.
Power sprayer nozzle selection of filters
The fan-shaped nozzle filter cylindrical, subdivided into two types: one is composed of the body, cover, filter screen, the other consists of body, cover, strainer, spring, ball, has anti - after drops function. Body, cover, material with a polymeric material, the filter, the ball, spring stainless steel, the life of sprayer nozzle is more than 400 hours. Filter pore size no larger than half the size of the nozzle hole. Usually fan nozzle can be equipped with a 50 mesh filter and a 100 mesh filter.
