Technical field

The utility model relates to the production technology of metal powder coating, relates in particular to a kind of adhering device of metal powder coating.

Background technology

Traditional metal powder coating working method is to produce end powder earlier, and then does mixed with metallic pigment.The metal powder coating that obtains like this has following shortcoming:

1. metallic pigment are prone to separate with end powder in the spraying process, and the effect instability causes dusting.

2. metallic pigment are very easily piled up at gun slot, stop up muzzle, and are prone to sparking, cause burning or blast.

3. the coating metal pigment after solidifying is prone to come off or is oxidized.

4. metallic pigment account for the total amount large percentage, and cost is higher.

5. appearance of coat is poor, and flow leveling is bad.

In order to solve above problem, key is to let metallic pigment separate with end powder particles, so need metallic pigment and end powder particles held tightly together in this step of mixing.The adhering device of common metal powder coating (claiming that also Bonding machine, nation decide machine) is that powder at the bottom of the powder coating is joined in the high-speed mixer with temperature control chuck; Utilize the high speed rotating of mixing equipment; Produce friction because of stirring rake with by movement velocity difference between the mixed material at short notice, frictional heat raises end powder mixture temperature.When end powder temperature is increased to the second-order transition temperature (Tg) near resin; Under the high-speed stirring of nitrogen protection and stirring rake; Rapidly metallic pigment are joined in the end powder of high speed rotating, make it be bonded in powder sub-surface at the bottom of the remollescent, then blowing processing under cooling rapidly.In this process; Because the bad control of temperature of the frictional heat between stirring rake and the material; The phenomenon of material caking occurs through regular meeting, and the reference mark of second-order transition temperature can not grasp well, the bonding that causes metallic pigment and end powder is not the effect of the best; Cause using the visual appearance of product of this metal powder coating poor, had a strong impact on production efficiency.
