There are many types of sprayers 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 factors that select the Trigger Sprayer(KEXON) 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 trigger 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 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; trigger sprayer 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.
For sprayers with a certain impact force, a small angle trigger sprayer should be used, and the liquid column flow (ie jet) is the best; the fan trigger sprayer is suitable for cleaning, degreasing, cooling, etc. The cone industrial trigger sprayer is suitable for drifting, surface layer, phosphating, Humidification, dust removal, etc.; venturi mixing trigger sprayer should be installed in the paint storage tank and tank body. Take the "H" type stirring trigger sprayer (also called venturi trigger sprayer) as an example. The bath liquid is inhaled through a certain pressure and the approach channel. The liquids are mixed and sprayed together at a flow rate of 1:4 to achieve the effect of mixing the solute without air, thereby preventing precipitation, because the agitation ensures uniform mixing of the chemical solution.
