    you are: Colouring in electric field

    In comparison with air dispersion colouring in electric field has following advantages: заказать электрические плиты .

    1. Tumanoobrazovanie is absent; paint losses are insignificant - the paint almost completely lays down on products. The economy of a paint in comparison with air dispersion makes 30-70%. Goon аптека. Goon трусики для мальчиков 9-14 кг.

    2. The paint lays down an equal layer.

    3. Colouring process is automated.

    4. Ventilation of painting chambers becomes simpler in the absence of a fog.

    The Products of the difficult form having sharp edges, acting edges, deep hollows, are not painted in electric field absolutely or painted partially as power lines do not reach them and paint particles on such sites are not besieged at all pli besieged in insufficient quantity. In such cases it is applied podkraska by pneumatic sprays.

    Coverings meet requirements of technology of colouring if the paint and varnish material is well sprayed. Ability to be sprayed in electric field depends substantially on physical and electric properties of the given paint and varnish material and from solvent. For example, such solvents as uajt-spirit, solvent, toluene, ksilol, others are badly sprayed in electric field, - acetone, difficult aethers, metilatsetat, butilatsetat - are sprayed well. Therefore in practice at manufacturing of painting structures mix various solvents-thinners which on the chemical compound should be combined well with binding paints.

    Electrostatic sprays are applied To dispersion of paints: rotating cups, fungi, disks or motionless slot-hole sprays.

    In rotating sprays mechanical forces that allows to apply the paints badly sprayed under the influence of forces only of electric field join action of forces of electric field also.

    In slot-hole sprays dispersion is carried out under the influence of electric field, the poet the corresponding choice of mother lov is necessary: is better varnishes (pigments), enamels gliftalevye and penta phthalic under condition of the additive of corresponding solvents are sprayed.
