Imitation (colouring by transparent paints) under more valuable plays wood of simple breeds large role in colour registration of furniture. Colour and a wood structure depend, first of all, on its breed. However colour of wood if necessary can be changed special dyes. Quality of imitation depends not only on dyes, but also from the wood which are exposed to processing.
In imitation walnut the birch, a linden, a beech, an alder are well simulated, is satisfactory - a fur-tree; under mahogany it is good - a pear, an alder, a cherry, an ash-tree, an elm, a beech, it is satisfactory - a fur-tree, a birch, a cedar; under a pink tree - well maple, it is satisfactory - an alder, a pear; under an ebony - well birch, an oak, a maple, a pear, an apple-tree, plum, a hornbeam, it is satisfactory - an aspen, a poplar, a beech.
To wood imitation apply various dyes (preparing from them solutions) which easily get into wood.
For wood colouring widely use nut bejtsy (guminovye dyes), and also every possible prograsses (copper or iron kuporos), hromovokislyj or dvuhromovokislyj kaly, margantsevokislyj kaly, chloric iron (chloric copper) with which preliminary poison wood, and then paint neprotravnymi dyes.
(An oak, a chestnut, a nut, etc.), it is possible to paint the Breeds of wood containing tannins without preliminary processing.
To preparation of painting solutions apply the water softened kaltsinirovannoj with soda (about 0,1%) or liquid ammonia (5%).
Heat up water to 60-80°Р, pour into it necessary (under the recipe), quantity of dye, stir before full dissolution and allow to settle during 48 ch. Settled solution merge in other ware. If the deposit part gets, a solution again defend and filter. Not dissolved deposit leaves on a surface of wood of a stain and a strip.
For more uniform colouring it is preliminary necessary to humidify a wood surface with water by means of a tampon or a rag.
The Prepared painting solution put on a wood surface only along fibres a brush, a spray, fatly moistened sponge, a pure cotton rag. After dyeing a wood surface wipe a pure rag, deleting the fat smudges leaving stains and strips.
That the painting solution got into a wood time more deeply, it warm up to 50-60°Р. The painted products should be dried not less than 1,5-3 ch at temperature not more low -f-18°C, but longer time before full drying of a paint is possible also.
To direct dyeing of wood apply various dyes. For example, for dyeing in krasnovato-brown colour of a birch, a beech, an oak on 1 l of water take 10 g nut morilki. For dyeing in krasnovato-brown colour of a birch take on 1 l of water 20 g nut morilki or 2 g dye "рѕсшэ" etc.
Besides direct dyeing, use protravnoe at which a surface at first process a solution of salts of some metals, and then, through 10-15 mines, paint with a solution which enters with a prograss reaction, forming insoluble connection in water. Depending on an applied prograss and its concentration colour of colouring of wood can be various. Endurance between drawing of a solution for etching and a solution for dyeing - 10 minutes
For example, wood of a pine and a larch paint in brown colour as follows: at first poison with a solution rezortsina (20 g on 1 l of water), then cover with a solution hrompika (10-30 g on 1 l of water). Endurance between etching and dyeing - 1 2 ch. A birch in imitation walnut paint so: poison with dye brown for fur (2-5 g on 1 waters), paint acid orange and hromovokislym kaliem (2-5 g on 1 l of water).
In practice of dyeing of wood many use the usual dyes intended for dyeing of cotton fabrics and fur. The solution fortress depends on intensity of colouring, it is better to use morilku.
After dyeing start transparent furnish.
