Product Description

 

Fully automatic wet paint production line

1.FEATURES & APPLICATION
The INFITECH fully automatic wet paint production line is suitable for applications with high capacity and uniform results. The needs of factory users largely depend on the type of paint selected and its viscosity, flash evaporation, drying, and curing time.
In the process of decomposing user needs, INFITECH's experienced engineers and technicians will comprehensively consider solutions for space, logistics, and energy consumption.
By using chain or rail conveyors to transport components to different processing processes, our paint production line can handle items of different sizes thanks to the latest dynamic detection technology for moving objects.

A typical three-stage system consists of the following

A typical three-stage system consists of the following

Cleaning - The process begins with the removal of obvious soil and contaminants. Depending on the material involved and the nature of the contamination, this can be done by mechanical means (such as blasting or scraping) or through the use of solvents, acids, or alkaline cleaning agents, applied manually or in machines designed for the purpose. This process cleans the part but generally does not add any protective material or process. The intent is to clean effectively without damaging the surface. Rinsing - Effective rinsing is a critical element in the cleaning stage. The rinse removes the cleaning solution and the contaminants that remain on the surface. Some rinse stages also include treatments such as conditioners or corrosion inhibitors. If the wash stage uses very hot solution, or if flash drying might be a problem between stages, a spray system may be installed between stages to prevent residual contaminants from drying onto the surface and to prevent flash rusting. Conversion Coating - Conversion coating strengthens corrosion resistance and prepares the surface to better accept the paint or other finish coating and promote long-term adherence.

Post-Treatment Rinse - After the conversion coating is applied, the surface is rinsed with water (sometimes deionized or treated with reverse osmosis) to remove any conversion agents that have not reacted with the substrate to form the coating. Rinsing also prevents the "migration" of chemicals from one stage to the next. Metal parts that undergo post-treatment rinse that includes a rust inhibitor demonstrate improved resistance to humidity and corrosion (up to ten times better). Drying - Treated parts must be absolutely and completely dried and cooled before paints or coatings can be applied. Drying or dry-off ovens are often used, with drying temperatures typically ranging from 250°F to 400°F. Parts that contain ferrous metals are vulnerable to flash rusting and must be dried quickly and thoroughly. Time, temperature, and air flow must be considered to ensure adequate drying and to prevent the formation of streaks and spots. Drying can also be done by evaporation, compressed air blow-off, air knife, infrared lamps, or cloth wiping. Drying and cooling are usually the most time-consuming steps in the cleaning and treatment process, so it's important to have enough equipment to prevent bottlenecks. Curing - During drying, water and solvents evaporate from the coating. During curing, a chemical reaction occurs to render the coating hard, inert, and relatively resistant to abrasion and corrosion. Air-dry coatings cure at ambient temperatures; baked coatings must be cured in ovens, generally at temperatures above 250°F.
