Some Basic Spraying Processes of Outdoor Steel Garbage Cans

I. What are the advantages of coating process of outdoor steel garbage can?


Compared with painting process, coating process of outdoor steel garbage can doesn't need painting, its construction has no pollution on environment and no harm on human body.


The coating appearance has good quality and strong mechanical strength, the curing time of coating construction is short, the coating has higher corrosion resistance and abrasion resistance, and outdoor steel garbage can will bear sun and rain, with good durability.


II. What is the working principle of coating process of outdoor steel garbage can?


Use electrostatic powder to coat equipment (electrostatic spray molding machine), and coat workpiece surface. Under electrostatic interaction, the powder will evenly stick to workpiece surface and form powder coatings.


The powder coating, after high temperature baking, levelling and curing, becomes final coating with different effects (different kinds of effects of powder coating).


III. What is the detailed coating process of outdoor steel garbage can?


There are four coating processes. First is pretreatment, get rid of oil stain, dust and rust, and form a layer of phosphate coating which is corrosion-proof and adds adhesion of coating layer.


Then electrostatic coating, spray powder coating evenly on workpiece surface, and use high-powered electrostatic spray molding machine to coat special workpieces (including electrostatic shield positions).


Next is high-temperature curing, heat powder coating on surface of steel garbage containers to a certain temperature and keep warm for a certain period, to make it melting, levelling and curing, and the workpiece surface will reach the desired effect.


Finally, decoration processing, namely make the workpiece after electrostatic coating reach a kind of special appearance effect, such as various wood grains, patterns, brightening, etc.


IV. What is the main processing step of high-temperature curing of outdoor steel garbage can?


The main processing step of high-temperature curing is putting coated workpiece into curing oven, heat to a certain temperature, open oven and cool down, then the finished product comes out.


The workpiece must be heated to a scheduled temperature, usually 185℃. Heat steel garbage containers to a scheduled temperature and keep warm for a certain time, usually 15 minutes.


V. What is the main decoration processing step of outdoor steel garbage can?


The main decoration processing step is glazing, transfer print, etc. Dustbins of various models produced by dustbin factories can take corrosion protection by coating process.


Coating process makes outdoor steel garbage containers more beautiful. And those containers have tidy surface and easy to clean, immune to sun and rain, with reliable product quality.
