New paint spraying technology - mixed gas spraying

2023-12-15 18:08:06
Mixed-air spraying is also called air-assisted spraying (AA-type spraying). As the name implies, this method is a combination of air and airless spraying. The quality of air spray is better, but the paint wave is larger and the film is thinner; while the airless spray has higher efficiency, lower coating waste, and thicker film, but the effect is slightly poorer. What kind of method can be used to retain the advantages of the two spraying methods and avoid their disadvantages? AA spray is produced on this basis. AA spray is to add a certain pressure (less than airless spray) to the paint, so that the paint itself can be atomized, while adding a small air pressure (usually not more than 2 kg) to adjust its complete atomization, The process is actually a secondary atomization process.

Self-Recovery Rapid Door

High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.

High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".

This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.

The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.

Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.

The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
