Technical characteristics (DECOgraphy)

The technology "DECOgraphy" is aimed at the production of innovative products, a special canvas that allows to apply patterns and images on the surface of concrete.

The basis of the canvas is made of the following components

The canvas is used in the process of manufacturing concrete products at the stage of formwork and makes it possible to transfer any image to products of concrete of any size -total tiles, wall and facade panels, art. elements, details of interior and decor.

The technology "DECOgraphy" uses a special method for the fabrication of the canvas, called "PRT_N series: impression of the image in the negative."

The basis of this method is the technique of applying the image to the paper surface: all the products are printed, that is, the images are applied to the canvas using a wide-format printer, the process is fully automated. Exception of the "human factor" allows to achieve high quality, image accuracy and high speed of production of finished products.

This technology should be used for concrete products made with high quality images. The image applied to the canvas is always printed in a mirror reflection, where areas with "air" in the finished product are sealed with contrasting paint, i.e. background area. In turn, without sealing the color, but with the application of the retarder, there remain places that, after solidification of the concrete, will act as parts of the drawing. Canvas in this technology is intended for the manufacture of concrete objects, viewed from a short distance, from 1 to 2 meters. Most often, these are small objects, the size of which varies from 100 mm * 100 mm to 2500 mm * 7000 mm. Typically, these are decor elements, art objects, paving slabs.

Using this technology, it is possible to realize images in concrete with an incredibly precise workpiece detail, in which the minimum object size can be 5 * 5 mm, and the minimum line thickness - 2 mm.

The optimal types of concrete for the use of this technology are:

• self-compacting concrete
• glass fiber reinforced concrete
• high-quality concrete
• decorative fine-grained concrete

When applying the technology to canvases, it should be borne in mind that in different ready-made concrete products the depth of washout of the upper layer treated with the retarder of solidification can differ. This depth is affected by many factors, such as:

• cement brand
• cement filler
• water-cement ratio quantity, quality and factors of additives effect
• plasticizers
• coloring agents for concrete

When using "PRT_N series" method, there is a basic depth for the compositions of certain brands of cement and types of concrete mixtures. It is necessary to take into account the error range, which primarily affects not the depth, but the thickness of the minimum object. Orientation follows the following values:

• With the use of the "PRT_N series" technology, the washing depth varies from 0.5 mm to 3.0 mm.

All these parameters will somehow influence the depth of washout and the clarity of the image, the errors of which can be discerned when viewed from close range. It should be borne in mind that there are clear patterns between the depth of washout and the clarity of the image, therefore, before casting the final product in concrete, it is recommended to use test samples to determine the optimum washout depth for given initial parameters.
