The working principle of the metal powder bonding machine is to add positive pressure on the basis of negative pressure and use special glue. For the processing of PVC series, due to high pressure, low temperature and short laminating time, its linearity and adhesion are unmatched by negative pressure equipment. It solves the problem of workpiece deformation (especially large-area workpieces) when processing negative pressure equipment, and greatly reduces the degree of deformation of the workpiece. Using advanced electronic new product control, the processing procedures such as entering, rising, heating, vacuum, laminating, unfilming, and table lowering can be automatically completed through adjustment. It is mainly powered by oil pressure and compressed air, so it must have sufficient air pressure and air volume. The frame is made of steel plates, and the overall structure is reasonable. The two workbenches can be recycled or used individually. The vacuum can be adjusted to low pressure first, then high pressure suction. The membrane pressure can reach 0.1~0.7Mpa dry air source. The product can achieve the ideal effect through adjustment.
This tool is used for electrostatic powder spraying, effectively connecting spraying, recycling, powder supply and other processes. After use of powder machinery, effective cleaning must be carried out.
Cyclone Screen: Under the action of induced wind, use a flat cardboard shell or stainless steel plate to seal the flange interface of the discharging device, and use a pure air source to blow away the powder in the screen. Disassemble the cyclone screen knife holder again, remove the screen knife, clamp the cover nut with an adjustable wrench, and another person rotates the motor crank counterclockwise to push out the screen knife.
The main and auxiliary grinding mills are first blown clean with pure air source, and the mechanical dust powder is sucked into the dust removal frame by the induced draft fan. The powder attached to the main and auxiliary mills needs to be wiped clean with acetone or Turner water to keep the inner surfaces of the main and auxiliary mills smooth and clean.
Cyclone Separator: Remove the baffle at the unloader flange interface, use a pure air source to blow off the powder on the inner wall of the cyclone separator, or use a high-power powder mechanical bucket vacuum cleaner to remove the powder adhered to the inside. wall. Then disassemble the connecting part of the upper part of the cyclone separator, take it out, and then clean it thoroughly.
Dust Removal Cabinet: First turn off the induced draft fan, cut off the power supply, and remove the dust in the dust removal bag. Open the recycled powder discharge valve to discharge the powder. Check whether the joint point of the dust bag is tight, close the discharge valve, and make sure the seal is tight. Cover the outlet with a plastic bag and seal it with self-adhesive tape to ensure there is no air leakage. Remove dust from the sealing area of the dust removal door to ensure its tightness when closed.
After each cleaning of the whole machine, the installation and connection positions of each component must be strictly checked using the candle method to ensure normal operation. Fine particles in paint can easily accumulate in the spray gun head or pipe behind the coating equipment, changing the direction of the air flow. When the accumulation reaches a certain level, they are sprayed out in a condensed state and adhere to the powder machine to be coated. In electrostatic spraying construction, environmental dust issues should also attract sufficient attention.

Precautions for Application of Metal Powder Coatings
Coating method of metal powder coating
In most cases, electrostatic spray gun is used for coating, because this type of product contains metal pigment. When using electrostatic gun for construction, excellent grounding of the system shall be ensured, and low electrostatic voltage and powder output shall be set together to avoid ignition during spraying. The effect of the coating film is closely related to the setting, quality or brand of the spray gun. After long-term spraying, a lot of metal powder may accumulate at the discharge needle of the spray gun, and the constructor is required to clean up the discharge needle on time.
Gloss of metal powder coatings
In most cases, due to great negligence, it is not recommended to use the gloss meter to measure the gloss of the metal appearance film, but only use the visual comparison method to judge whether it is the same as the standard sample.
Recoverability of metal powder coatings
As for the powder manufactured by dry mixing method, because there will be differences in the spraying and recovery processes, there will be certain differences in the metal pigment content between the recovered powder and the new powder, which may lead to different appearance of the film and color deviation. This is due to the different properties between metal pigment and powder particles. Experts suggest that the ratio of recovered powder to new powder should be at least 1:4. Assuming that the powder coating manufactured by the bonding and fixation method can recover the powder from scratch because the ratio between metal pigment and powder particles is relatively fixed.
Gloss coating of metal powder coating
Spraying a gloss coating on the metal powder coating has the following benefits: enhancing the stone impact resistance of the metal powder coating; Increase the beautiful effect of metal powder coating; Completely handle the abradability of metal pigments; Weather resistance of metal powder coating. In order to ensure the appearance effect of the gloss layer, the workpiece sprayed for the first time shall not be polluted. Therefore, it is generally required to have a fully automated spraying line and two sets of independent spraying rooms for coating respectively. In general, it is recommended not to spray the finishing layer. It only needs to be used when the requirements are very high, such as high-end household appliances, car wheels and outdoor applications (to ensure weather resistance)
Abradability of metallic pigments
Whether the powder is made by dry mixing method or bonding fixation method, it can not completely deal with the problem of abradability of metal pigments. The only way to deal with the abradability is to spray a clear coating on the metal powder coating.
Adhere to the method of metal powder coating appearance together
For the same product, try to use the same batch of metal powder coating to avoid the problem of poor quality between batches of powder coating.
Try to keep the spraying conditions stable. Use the same set of spraying equipment and the same parameters such as voltage and air pressure; Try to keep the interval between the spray gun and the workpiece unchanged, and try to keep the film thickness stable; Ensure that the powder coating is fully fluidized before spraying; When using recovered powder, ensure that the ratio of recovered powder to new powder is at least 1:4; Try to avoid using metal powder coating to spray the workpiece with disordered shape or deep depression; It is recommended that multiple workpieces assembled together should be sprayed together.
What Is the Process of Powder Bonding
Bonding a powder coating base involves heat. The base powder is heated, but only just enough to soften the particle. Then, metallic flake is added through mixing. Since the powder particle is soft, the flake will adhere/stick to the particle.
