The factors that use the 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 fine mist sprayer injection is to maintain continuous contact of the bath with the workpiece. This factor is more important than pressure.

The temperature of the liquid does not affect the fine spray performance of the fine mist sprayer, but it affects the viscosity and specific gravity, as well as the choice of material. The material of the fine mist 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; fine mist sprayer materials for phosphating baths are generally made of acid-resistant stainless steel, and fine mist sprayers for preventing corrosion may also be directly selected from stainless steel or Made of nylon material.

For fine mist sprayers with a certain impact force, a small angle fine mist sprayer should be used, and the liquid column flow (ie, jet) is the best; the fan fine mist sprayer is suitable for cleaning, degreasing, cooling, etc. The cone fine mist sprayer is suitable for drifting, surface layer, phosphating, humidifying. In the aspect of dust removal, etc.; the venturi mixing fine mist sprayer should be installed in the paint storage tank and the tank body. Take the "H" type stirring fine mist sprayer (also known as the venturi fine mist sprayer) as an example. The bath liquid is sucked through a certain pressure and the approach channel. The liquid is mixed and sprayed together at a flow rate of 1:4, and the effect of the solute without air mixing is achieved, thereby preventing precipitation, because the agitation ensures uniform mixing of the chemical solution.
