you are: Economic indicators of colouring and drying

The expense of these materials develops of quantity of the materials put on a surface of products, and losses - technological and organizational. обои москва

As Organizational losses are called the losses which are taking place at storage of materials, manufacturing of working structures and deliveries of the last to a work place.

Technological losses depend on a method of drawing of coverings.

At colouring by pneumatic dispersion the part of the paint which have not settled on a surface products, is lost in the form of a dust; similar losses though and considerably smaller, take place and at vacuum dispersion and colouring by douche; at colouring okunaniem the paint part settles on a bottom and on bath walls.

At any method of colouring connected with application of conveyors, losses of the materials settling on various adaptations - hooks, whatnots and conveyor parts are observed.

The Volume of losses of materials at colouring okunaniem, pneumatic and vacuum dispersion depends also on the form (configuration) of products. The least losses take place at colouring of products of a simple configuration - sheets, boards, cowls, casings, beds. At colouring of products of a difficult configuration - cars in the gathering, different small details, mechanisms with partially painted surface, paint losses sharply increase.

As much as possible admissible organizational and technological losses of paint and varnish materials in% from the quantity necessary for reception of a covering, make:

At colouring by a brush - 10

At colouring by vacuum dispersion - 8-15

At colouring in electric field - 10

At colouring okunaniem - 20-25

At colouring by douche - 10

At colouring by pneumatic dispersion for paint and varnish materials on a basis kondensatsionnyh pitches and for oil paints - 20-50

At colouring by pneumatic dispersion for paint and varnish materials on a basis polimerizatsionnyh pitches and cellulose aethers - 25-60
