Service life of steel pretreatment line
Steel through the roller conveyor after preheating sent to the shot blasting cleaning room, multiple high efficiency shot blasting machine with different coordinates orientation to use the projectile on its intensive striking and friction, so that the surface of the oxide, rust and dirt quickly off, steel surface cleaning and strengthening.
Practice has proven that most of the deep defects come from poor surface treatment, any paint in the treatment of poor surface can not play its good performance, in the oxidation, rust, oil surface coating, both time and cost, are a big waste, high grade surface treatment quality will extend the life of the paint.
In the blasting process, the scattered pellet dust mixture by the chamber funnel and longitudinal spiral conveying gathered in the lower part of the elevator, and then lifted to the upper part of the machine separator for pellet dust separation, the separated pellets fall into the separator hopper, sent to each blasting machine by the shot pipeline for recycling.
Painting on the surface of oxidation, rust and oil is a big waste of both time and cost, and the high grade of surface treatment quality will extend the service life of the paint.
In order to give full play to the protective and decorative effect of the paint on the substrate, in addition to the quality of the paint itself, the quality of the surface treatment of the substrate and the level of construction directly affect the quality of the painting project.
The main factors affecting the development of wear and tear are: the quality of the equipment, the degree of load, the technical level of the operator, the working environment, the quality and period of maintenance and repair, etc.
This kind of wear and tear can occur in the use of machinery and equipment or in disuse. Equipment in idle is easy to be ignored and not maintained, so the natural wear and tear caused by equipment in idle is more obvious than in use, and more easily ignored.
