The pretreatment method is divided into liquid processing and dry processing.Hanna offers you reasonable and economical pretreatment methods to clean your workpiece.According to the product size, different processing forms can be selected, the structure is reasonable and the ideal use effect can be
The problem of rust return between the pretreatment processes of the workpiece has become the most concerned issue for customers. After the workpiece is rusted, it directly affects the pre-treatment film quality, which in turn affects the coating effect. Therefore, how to do rust prevention between processes is one of the key tasks in pretreatment.
Common faults and analysis during electrostatic spraying 1. Host gun insurance blown (1A) 1A gun insurance2.When the spray gun enters the water, the high-voltage static electricity is short-circuited, the system is in protection, the output voltage is very low, and the spray gun is fully dried, and the water source is checked and disposed to ensure that the compressed air is monotonous.
One: cleaning of the electrostatic spray gun After use, the spray gun and its accessories should be cleaned immediately. Improper maintenance and cleaning will increase the incidence of spray gun failure.
The production of powder coating spray booth is the key process in the spraying production process. The key to the quality of the surface of the sprayed workpiece lies in the control of various process parameters during the spraying process. The amount of powder and atomized air are two key technical indicators.
Considering from the powder coating, if the matching between the resin and the curing agent is unreasonable in the formulation design, for example, the reactivity selection of the resin or the selection of the type and amount of the curing agent is unreasonable; the mass percentage or the volume concentration of the filler is too large, etc. Will affect the physical and mechanical properties of the film.
