Embodiment 1
[0027] Prepare the fluorocarbon powder coating for industrial equipment anticorrosion according to the following steps:
[0028] In the first step, the raw materials of the following formula are premixed according to the weight percentage,
[0029]
[0030] In the second step, use a twin-screw extruder to melt and knead the pre-mixed raw materials, disperse them evenly, and carry out melt extrusion; the temperature in the extruder I zone is set at 105°C, and the temperature in the extrusion zone II zone is set at 105°C. Set at 95°C.
[0031] In the third step, the extruded material is pressed into tablets, cooled, and crushed, and then the ACM mill is used to finely pulverize the crushed material, and the particle size of the crushed material is 15-65 microns.
[0032] The fourth step is to carry out standard sieving of the finely pulverized powder, and the specific requirements are to use
[0033] Use a 180-mesh rotary sieve to sieve the powder coating to a median partic...
