Sprutning

Sprutning refers to the process of applying a liquid as a fine spray or mist using a spray device. It is used to describe various techniques and equipment designed to atomize liquids into droplets and project them onto a target surface, volume, or air. The term is common in Swedish technical and industrial contexts and encompasses both manual and automated systems.

Different methods exist for achieving atomization. Air-assisted and airless spraying use compressed air or fluid pressure to break up the liquid into droplets. Atomizers, sprayers, spray guns, and nozzle geometries determine the spray pattern, droplet size distribution, and coverage. Electrostatic spraying charges droplets to improve adhesion and reduce waste. The choice of liquid properties—viscosity, surface tension, and flow rate—along with pump pressure, nozzle size, and distance to the target, influences performance.

Sprutning is applied in many sectors. In painting and coating, it enables even coverage with relatively low material use. In agriculture, sprayers deliver pesticides, herbicides, or fertilizers to crops. Industrial processes use misting for cooling, humidification, or surface treatment, while fire suppression and cleaning applications also employ spray technology.

Safety and environmental considerations are important. Proper ventilation, respiratory protection, and containment reduce exposure to aerosols. Nozzle selection and calibration minimize drift and waste, and formulations should meet regulatory guidelines for worker safety and environmental impact.
