Pre -selected carpet cards are laid on the black surface of the uped site along the layer of a cement solution 2 cm thick. After the solution hardens at a normal temperature (4-6 days), the paper is washed off and the surface is processed as. It is said above. Although the quality of the surface is quite satisfactory, the disadvantage of this method is the complexity and duration of the production process.
Currently, the mosaic carpet is laid on a freshly fixed surface for about 1 hour.
Laying a mosaic carpet in the form as it is performed now is still very imperfect.
The seams of individual cards, of which the mosaic carpet consists, often do not coincide, since in colored stripes of cards and individual tiles there are different thicknesses. To eliminate these defects, it is necessary that the manufacturer will increase the size of the cards and release them in special containers folded into rolls.
With the further development of a rational way to lay carpet mosaic on a freshly grounded landing using a shield, it is necessary:
1) construct a hard metal shield to ensure a flat surface of a mosaic carpet on the landing; The shield should consist of two separate parts: the shield itself for the preliminary assembly of the carpet and the metal frame necessary for its transfer to the tap to the freshly formed site;
2) link the weight of this shield with the carrying capacity of the lifting and transport mechanisms available at the plant;
3) make the shield portable and turning over around its longitudinal axis;
4) to achieve the shield quickly and accurately fit on the surface of a freshly formed site and after a short period after laying is removed and freed from the mosaic carpet.
