    you are: Thermoradiating sushilnye chambers

    Speed of drying in thermoradiating chambers depends on distance from a radiator to a product surface: at distance of 100 mm the paint dries up for 3 mines, at 300 mm - for 10 mines, at 500 mm - for 36 minutes

    Speed of drying influence thickness.) skins of products (at a thickness of walls of 2 mm duration of drying makes 3 mines, at a thickness of walls of 50 mm - 30 mines), and also a sort of a paint and its colour. The thermoradiating method of drying for melaminoalkidnyh and mochevinnyh enamels is most effective; is less effective for gliftalevyh and pentaftalevyh and even less for oil enamels; paints of black, brown, dark blue, red colours, and more slowly paints of grey, beige colours fastest dry up. To cast products with thickness of a wall more than 30 mm to apply thermoradiating drying it is not recommended.

    At drying on suspension brackets it is necessary to complete the products having about an identical thickness of walls the form that provides uniform heating of a surface of products.

    Drying of details in baskets and protivnjah is inexpedient, as a part of a surface of the products which are in baskets and protivnjah, does not get under influence of infra-red beams and dries slowly or does not dry up at all.

    At drying in thermoradiating chambers a product of a difficult configuration non-uniform drying of a paint takes place: it is observed perezhog paints on arriving parts and the slowed down drying in deepenings. To drying of products of the difficult form apply radiatsonno-konvektsionnye chambers. In sushilnyh devices of such type drying is carried out simultaneously by radiators - nagretymi panels or torches circulating air.
