Dry paint is a powder massFine grinding, the particles of which, during sieving, can pass through the cells of the smallest diameter. The quality of the pigments directly depends on the degree of grinding.
To obtain the finished composition, the paint is mixedwith a binding mass. Pigments are classified as metallic, synthetic and natural. The latter are created by enriching, grinding minerals and rocks followed by thermal processing. Metal compounds are obtained by pulverizing the metal alloys, and artificial (synthetic) are the result of chemical processes. The most popular among the metallic type pigments is bronze and silver aluminum powder.
Calcination allows determining the inorganicand organic origin, for this purpose the powder is filled up in a special container or on a sheet of steel and heated. Thanks to carbon, the organic paint dry gets dark.
It is important to remember the toxic properties when working withstaining materials of any type. To the category of poisonous is the paint is dry, which has elements of zinc, copper and arsenic. In the presence of such compounds, the method of applying with a brush is more rational, thereby minimizing the likelihood of poisoning. The harmful effect is more pronounced when using atomizers, nebulizers and other devices with a similar principle of action. Regardless of the application method, strict adherence to safety rules and the use of a protective mask or respirator are necessary.
Quality dry paint for concrete does not deteriorateand does not change the shade in the alkaline environment, with the ultraviolet rays, with systematic drying and as a result of repeated exposure to moisture. Such properties are characterized by ultramarine, ocher, umber, sienna, mummy, cinnabar, manganese peroxide; pigments: orange, scarlet, burgundy and lemon. Their use is possible in all paint formulations, others are used in glue-type paints, as well as in emulsion paints.
To get certain tones, you needmixing of various dry elements. Pigments must be soaked in water before use, mix thoroughly and add to the coloring compound with continuous stirring. When directly mixed with paints, there is the possibility of incomplete dissolution, which will lead to the appearance of noticeable bands on surfaces that have been painted.
Powder paint of aluminum and bronze colorIt is used for painting metal surfaces and metals under condition of dilution with varnish or varnish. The most common is in the decoration of old mirrors, frames for paintings and other interior items.
Alkali-resistant compounds are used to apply to ceilings and walls - it's ultramarine, umbra, ocher, iron curl. A distinctive feature is the possibility of application for any paints.
There are different shades of colors:black, red, brown, blue, yellow and white. The latter include lime, white and chalk. The chalk is realized in a powdered form with a yellow or gray tint, as well as white large lumps. These varieties are divided into three varieties. For the application to the wall structures, chalk is used with the finest grinding, which resembles the flour of the highest grade.
Air-type lime is most often usedfor painting exterior and interior walls. The hydrated appearance can be mixed with dry pigments that do not change shade, such as calcareous colors of yellow, red and blue, as well as burnt bone, umbra and ocher.
White is a white powder of thingrinding. The dry paint composition of this type includes the ground elements of titanium ores, lithopone, lead, steel zinc. The most common white was taken as a component for oil stains and putty.
Ultramarine and azure are classified as bluepigments. Azure is added to strengthen the shade in the soot and is used for the production of enamel and oily base paints. It is characterized by darkening when exposed to ultraviolet radiation, because of this, its use is possible only in internal works. Sink (ultramarine) - the paint is dry with a green or blue tinge, is a component for calcareous and chalky substrates.
Burnt sienna, crowns and ocher belong to the categoryyellow pigments. Ocher has a distinctive firmness and different tones. For example, after careful calcination, you can get a red-brown tint with the name of burnt ocher. Crowns include pigments with a color range from orange to bright-lemon. With ocher has a similarity in the characteristics of burnt sienna. It has become most common for applying to vertical planes under ash or oak.
Lead and iron marmot, mummy, vermilionare red pigments. The last powder paint differs relative stability and is used for internal works due to exposure to sunlight. Lead oxide is a color orange-red color, used strictly for outdoor work, due to high virulence. Mummy can have a light and dark shade of red. Despite the relative durability, it is not used for outdoor work. Can have natural and artificial origin. During painting, it has a bright tint, which becomes darker after some time and turns into red-brown.
Chromium and lead greens belong to the categorygreen pigments. Chromium oxide is a mixture of yellow crowns and azure, while reducing or increasing the amount of the latter, it is possible to obtain other colors. Lead greens are also obtained by mixing yellow and blue inks.
Charcoal, soot and manganese peroxide areblack powder paint. The composition of carbon black, obtained during the processing of gas or oil, can only be mixed with oil solutions, soap and adhesive liquid.
