In the process of spraying aluminum profiles, more attention needs to be paid, and the handling must be standardized. Aluminum profiles are more beautiful and durable in future use. Next, let's take a look at the details that need to be paid attention to.
Before the formal powder spraying, you can try spraying several times. At this time, you can observe the size of the powder amount and the uniformity of the powder distribution at both ends of the spray booth.
At this time, the powder runs in a straight line within 10cm from the end of the spray claw, and the other part is in the form of atomized powder. The powder adsorbed on the surface of the aluminum profile is actually the powder with this atomization effect. Is there such a mist? The powder for the chemical effect is used as a standard to control the distance between the spray jaw and the aluminum profile.
The clamps hanging at both ends should ensure that they can bear a considerable weight of pressure; the clamps used in the middle part should minimize the size of the contact point between the clamp and the outer surface of the aluminum profile during the production and use process, and should be placed vertically in time. The hanging rod part of the aluminum profile should be filled with powder, and the hanging position in the hanger of the industrial aluminium profiles should also follow the corresponding principles.
The pretreatment process is simpler than the common pretreatment process before oxidation, mainly degreasing and chromating, and the consumption of raw materials is low. In the pretreatment process, in order to improve the production efficiency and reduce the energy consumption in the drying process, a larger material rack is often used, and as many pretreatment processes as possible are installed.
For some softer profiles, more crossbars should be placed in the middle of the profiles, and the grooves should be placed upwards as much as possible, which is conducive to the evaporation of water.
When there is still water remaining after the drying process, in order to avoid damage to the surface of the aluminum profile and the profile is easily deformed when the temperature is too high, the aluminum profile should not be placed in the furnace for baking. Dry with an air gun (no oil and gas).
In addition, the aluminum profiles must maintain a proper inclination angle when entering and leaving each slot and during the drip drying process, but it is easy to cause some profiles to slip off. A stainless steel wire mesh should be bundled at one end of the material rack as a preventive measure.
In short, when spraying aluminum profiles, pay attention to the processing of the above-mentioned details, which can prolong the service life in the later stage.
