Effect of plasma treatment (He/CH4) on the glass surface for the reduction of powder flux adhesion in the spray drying process

Effect of plasma treatment (He/CH4) on the glass surface for the reduction of powder flux adhesion in the spray drying process

A 50Hz glow discharge He/CH4 plasma was generated and applied for the glass surface modification to reduce the powder adhesion on wall of spray dryer. The hydrophobicity of the samples determined by the water droplet contact angle and adhesion weight on glass, dependent on the CH4 flow rate and plas...
