Foreword: Powder coating is a kind of environmentally friendly coating that does not contain solvent and has an average particle size of 35 microns.

1 Raw material part

The curing agent passes through the airflow crushing equipment, and the material is repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure airflows.

It can be seen from Table 2 that after the curing agent is modified, the solid specific surface area is significantly increased, and the particle size is significantly reduced

2 Test part

Jet mill (preparation of curing agent), Omega SCF-106 laser particle size analyzer, impact meter, bending tester, double screw extruder, electrostatic spray gun, constant temperature oven

The preparation of the coating film is carried out according to GB/T 1727-1992 "General Preparation Methods of Paint Films"; the impact resistance of the paint film is measured according to GB/T 1732-1993 "Methods for the determination of the impact resistance of paint films"; the flexibility of the paint film is according to GB/T 1731-1993 "Measurement Method of Paint Film Flexibility"; paint film adhesion shall be measured in accordance with GB/T 9286-1998
