METHOD OF METAL VESSEL TREATMENT WITH ELECTRIFIED SPRAY

摘要

FIELD: technological processes; paint. ^ SUBSTANCE: invention concerns ecology and construction and can be applied in electrified spray treatment of metal vessels used as moulds in construction block and panel production. The result is achieved by dielectric fluid spray electrification by passing it at high speed of 30-60 mps over narrow dielectric channel of 1-1.5 mm diametre. Electrified spray jet with negative charge is encircled by guiding cocurrent air flow. High voltage is applied to the processed metal surface to create potential difference of about some thousand Volt between spray drops with negative charge and processed metal surface. ^ EFFECT: reduced settlement time for fine dispersion fraction of dispersed spray, enhanced homogeneity of fluid layer dispersed in the form of electrified spray on metal vessel surface, reduced quantity of sprayed fluid required. ^ 1 dwg
