DEVICE FOR DEPOSITION OF POLYMER POWDER COATINGS

摘要

FIELD: deposition of coatings from powdery materials with the help of air spraying; may be used in application of coatings to articles in various industries. SUBSTANCE: device has grounded body with channel from dielectric for passage of air-powder mixture. Channel is made from successively connected parts. Each part is located at an angle alpha to previous one. Device also includes spraying nozzle. The angle alpha is taken within <EMI ID=0.241 HE=6 WI=24 TI=CHI>. Body consists of two connected parts. Channel for passage of air-powder mixture is made between surfaces of connected parts contact. EFFECT: provision of efficient charging with reduced overall dimensions and weight of device. 2 cl, 3 dwgg
