There are many types of the Trigger Sprayer(KEXON), and the range of choice is large. Generally speaking, sprayers for degreasing and water washing processes can be selected with jet sprayers with strong impact force: the "V" type fan nozzle is taken as an example, and the spray angle 60 degreeis the best, with a large impact force; and the nozzle of the phosphating process can choose a centrifugal nozzle with good atomization, fine water particles and weak impact force: take "Z" type cone nozzle as an example The optimal distance of the nozzle from the workpiece is 40cm ~ 50cm, and has a spray effect of dispersing and atomizing the liquid. The arrangement of the sprayers on the nozzle can be in the form of parallel and cross, and the channel type adopts vertical cross arrangement, and the spraying effect is better.

The factors that select the trigger sprayer are flow, pressure, spray angle, coverage, impact force, temperature, material, application, etc., and these factors are often intertwined and mutually constrained. Flow and pressure, spray angle and coverage are proportional. The purpose of any nozzle injection is to maintain continuous contact of the bath with the work piece. This factor is more important than pressure.

The temperature of the liquid does not affect the spray performance of the trigger sprayer, but it affects the viscosity and specific gravity, as well as the choice of material. The material of the trigger sprayer should also be determined according to the chemical characteristics of the bath. For non-corrosive baths, bronze casting or plastic die casting can be used according to the difficulty of processing. In order to prevent corrosion, non-metallic materials may be used; for strong etching baths such as sulfuric acid and hydrochloric acid, nylon plastic may be used; nozzle materials for phosphating baths are generally made of acid-resistant stainless steel, and sprayers for preventing corrosion may also be directly selected from stainless steel or made of nylon material.
