    • Colouring by pneumatic dispersion. A type spray kr-20

    you are: Colouring by pneumatic dispersion

    Sprays of marks KR concern sprays of external mixing, ZIL, 0-31А; to sprays of internal mixing - КРП-2, 0-45, С-592, etc. .

    The Spray of type КР-20. Its case is made of an aluminium alloy. The paint can arrive on channels in the chamber. Compressed air moves through a tube, channels both in the ring chamber and through an aperture outside. By pressing the doggie works a cartridge, the air channel and zapornaja a needle opens, the paint from the chamber arrives in a nozzle, whence follows outside and on an exit is picked up by a stream of compressed air. In the ring chamber there are four additional apertures for air giving. In ledges of a head of an air nozzle there are channels. Turning a head, it is possible to establish it so, that channels will coincide with apertures in the ring chamber. Then air, leaving channels, will flatten a paint torch, giving to it almost flat form. If channels do not coincide with chamber apertures, the conic stream is formed. At colouring of large-sized products of a simple configuration the flat torch is expedient; At colouring of products of the small sizes and a difficult configuration - a conic torch. The paint to a spray can arrive samotekom from a glass located over a spray, through the channel. If the glass is attached from below under the spray case the paint from it is sucked in by air and arrives through the channel. Capacity of a glass for a paint of 0,5 l. At great volume of works the paint to a spray moves on hoses from separate kraskonagnetatelnogo a tank.

    In the course of dispersion some part of a paint does not reach a product or is reflected from its surface, the fog is formed, losses of a paint which manage to be lowered by application of new sprays of mark КРУ-1 superseding КР-20 take place.
