LED aluminum profile in the spraying process need to pay attention to a lot of places, processing must be correct specification, convenient use after beautiful and durable. Let's take a look at the details that need to be paid attention to in the coating process of LED aluminum profile.
1. The production of fixtures and the selection of materials: The hanging fixtures at both ends must be guaranteed to bear a considerable weight of pressure. In the process of making and using the fixture used in the middle part, the size of the contact point of the fixture and the outer surface of the profile should be reduced as far as possible, and the part of the suspension rod placed vertically should be supplemented in time. The suspension position of the profile should also follow the corresponding principle.
2. Spray room should pay attention to the problem: Before the formal spray, can try to spray several times. At this time, the size of powder quantity and the uniformity of powder distribution can be observed at both ends of the spray chamber. At this time, the powder runs in a straight line within 10cm from the nail end, and the other parts exist in the form of atomized powder. The powder adsorbed on the surface of the profile is actually the powder of the atomization effect. The existence of the powder of the atomization effect is the baseline to control the distance between the nail and the profile.
3. The spraying process is simpler than the ordinary pretreatment process before oxidation, mainly degreasing and chroming, and the raw material consumption is lower. In the process of spraying treatment, in order to improve production efficiency and reduce energy consumption in the drying process, large material racks are used. For some soft profiles, the transverse bar should be placed in the middle of the profile, so that the groove part is placed upward as far as possible, which helps the evaporation of water.
4. When the drying process is completed, there is still water residual, in order to avoid breaking the LED aluminum profile surface of the impact film and the temperature is too high when the profile deformation, should not be put into the furnace baking, can be used to cool dry or blow dry with air gun. At the same time, the LED aluminum profile in and out of each groove and dripping process, must maintain the appropriate tilt Angle, but part of the profile easy to slip, one end of the material frame must be bound stainless steel wire mesh as a preventive measure.
In the LED aluminum profile spraying link, we should pay attention to the above details, can extend the service life of LED aluminum profile.
