Sethunya sa ho fafatsa ka motlakase

Poleloana e reng "electrostatics or electrostatic spray finishing" e bolela mokhoa oa ho qetela oa ho fafatsa moo litefiso tsa motlakase le masimo a motlakase li sebelisoang ho hohela likaroloana tsa thepa ea ho roala atomo ho sepheo (ntho e lokelang ho koaheloa). Mefuteng e tloaelehileng ea mekhoa ea motlakase, litefiso tsa motlakase li sebelisoa ho thepa ea ho roala 'me sepheo se thehiloe fatše, ho theha sebaka sa motlakase. Likaroloana tse qosoang tsa thepa ea ho roala li huleloa ke lebala la motlakase holim'a sepheo se theiloeng ka lebaka la ho hoheloa ke litefiso tsa motlakase tse hanyetsanang.

Electrostatic spray charger e ntlafatsa bokhoni ba phetisetso ea lisebelisoa tsa ho qetela tsa spray. Lintlafatso tsa ts'ebetso ea phetisetso li etsahala hobane matla a motlakase a thusa ho hlola matla a mang, joalo ka lebelo le phallo ea moea e ka etsang hore lisebelisoa tsa atomized li hloloheloe sepheo se reriloeng.

Sistimi ea ts'ebeliso ea electrostatic spray e kenyelletsa sistimi ea phano le sistimi ea ho tjhaja. E sebelisa bethe e nang le metsi e le sehopo sa phepelo ho nosetsa phofo le ho sebelisa moea o hatelitsoeng ho pompa ntlheng ea sethunya sa spray.

Sethunya sa spray se etselitsoe ho hlahisa tefiso ea electrostatic ho li-powders le ho e lebisa mosebetsing o thehiloeng fatše. Ts'ebetso ena e etsa hore ho khonehe ho sebelisa litlolo tse ngata tse tšesaane tse nang le likarolo tse fapaneng tsa mokhabiso le tse sireletsang.Tefiso ea electrostatic e ka hlahisoa ka motlakase, e bitsoang tribo charging, ka ho kopana le ka hare ho sethunya, kapa tse ling tse bitsoang corona tjhaji.

Lenaneong la ho tjhaja ha corona, jenereithara e phahameng ea motlakase e sebelisoa ho lefisa eleketrode ntlheng ea sethunya sa phofo. Sena se theha lebala la electrostatic (kapa corona) lipakeng tsa sethunya le substrate. Limolek'hule tsa khase moeeng li nka lielektrone tse tsoang ho corona. Tefiso ena e mpe, ka lehlakoreng le leng, e fetisetsoa ho likaroloana tsa phofo ha li ntse li tsamaisoa ho tloha hloohong ea sethunya ho ea ho substrate. Likaroloana tsa phofo tse qosoang li beoa holim'a substrate e entsoeng ka mobu.
