The invention relates to a group of inventions in the field of production technologies interior-facing products from plaster materials and can be used successfully in the production of building materials.

Presents a method of manufacturing a highly artistic, architectural and expressive, interior-facing products such as mosaic, of gypsum binding materials for walls and ceilings, includes a method of manufacturing lightweight products from plaster with high hardness of the top surface, with high adaptability and simplicity of the products without the use of complex industrial equipment and energy costs and wear-resistant heavy-duty form for the production of gypsum, differing availability in the manufacture.

The proposed technology allows you to quickly organize production of cladding products from plaster at home with minimal cost. The simplest method of making molds for production of products of all sizes and configurations of the drawings allows you to quickly adjust the volume of such production due to the possibility of creating additional jobs without too much money on equipment.

A known method of manufacturing cladding gypsum products, including the preparation of the molding mixture, for which ivko in a form in which the previously laid strip-matrix, exposure to complete curing, the dismantling of the product with a gasket, its separation, drying and finishing products. As strip-matrix use cellophane film, which is pre-incubated for 0.5-3 minutes in water at a temperature of 30-50°C. the Specified film processing provides reception on the surface of the decorative texture under the skin.

Known form matrix for the manufacture of construction products with a relief pattern, containing a polymer shell and a filler. Polymer shell made anti-adhesive and filler from sand-cement concrete containing ferromagnets in the amount of 10-20%. The matrix produced by the model with the specified first relief pattern in the form of an open tank, the shape model is then inverted - relief down the capacity of the fill composition, consisting of a concrete mixture and the ferromagnetic bodies, and after hardening of the concrete tank is closed by a flat film and the matrix used in the molding of construction products.

Also known form for the manufacture of interior finishing products made with a raised pattern on the pallet, where the matrix used spatial polymeric gasket, congruent working surface and forms, and it is provided with a shoulder arranged on the sides of the form and covering them outside height of the form and the form has a removable sealing cap made with the possibility of supporting it on the shouldered. As a water-repellent composition is used nitroanaline paint. The mixture in the form fill in excess of its volume by 15-20%. When this form is made of fast-curing composition by pouring it into the established on the basis of the inverted matrix. When this form is made of gypsum. The matrix is made of sheet plastic or heat-resistant polymer film, and the sealing cover is made of thick plate glass, corrugated bottom. All these forms have a number of disadvantages which adversely affect the quality of products from plaster, and make the production process of multi-operational, time-consuming and inefficient.

First, the use of polymer matrix strip, PVC film requires additional costs for the production of forms, adding the use of energy-consuming equipment that are not acceptable in simple conditions, and the resulting polymer strip is thin and fragile product, which after several cycles of manufacturing products damaged when exposed sealing cover and quickly breaks down, therefore, the resumption of production is DSTV will require additional monetary and time costs. Secondly, in the described case, apply gypsum stand, which gives the form of rigidity. But the phase transformation of a plaster solution necessarily accompanied by intramolecular extension, which makes it impossible to retrieve articles of plaster base. The use of an air gap between the inner wall plaster pedestals and the exterior surfaces of the matrix strip of PVC requires more effort and does not allow for strict products sizes. Produced in this way products require substantial revision manually, i.e. pruning. And the fact that in all the above cases, fill, shut solution in the form is carried out simultaneously and is sealed with a sealing cap, could not ensure the removal of excess moisture and air, formed during mixing, which subsequently (after drying products) leads to the formation of hidden cavities and voids over the entire area of the product. Use nitro on such products requires a large cash outlay on enamel and varnishes (of the order of 60 to 150 rubles. per 1 sq. m), because hidden voids absorb the paint unevenly. These products are required to cover 4-6 times. And, finally, the application nitroanilide coating negates the natural advantages of gypsum to absorb and lose moisture, without being destroyed, while maintaining a favorable microclimate inner the and accommodations. All these shortcomings significantly complicate the use of such a production method in simple terms. It requires significant manual labor and the use of complex energy-consuming equipment in the manufacture of matrix strips PVC, polymer films and coating. A new method completely solves these problems and makes the production of gypsum products available, harmless and easy in contrast to previous.

The task is to develop a more economical way of manufacturing products curly mosaic of gypsum with high hardness front surface for walls and ceilings with high adaptability and simplicity in execution, allowing for minimal cost to provide high quality products with preservation of the original natural advantages of gypsum. And also to create a form for the production of interior-facing products from plaster, more durable, available even in simple terms without energy consumption and the use of complex mechanisms.

The problem is solved in that the prepared molding a mixture of plaster and water is poured in solid form, executed entirely of material having a higher strength than gypsum and PVC film, and the shape is not shared on the pallet and matrix Pro is a Lada. The entire production process consists of mixing, pouring it into a mold, seal pressure plate, shutter speed to complete curing and extraction of the finished product. It should be noted that manufacture such products differ in the severity of sizes and do not require significant additional manual.

To preserve the natural qualities of the plaster and make products of artistic expression in the coating is homogeneous of manufactured products composition. The monolithic structure of the coating is achieved in the complete absence of glue and paint substances due to the natural properties of the hardening of the plaster when exposed to water. Such monolithic decorative coating allows gypsum products to perform the function of controlling the humidity of the environment. It should be noted that all processes with this method of production of gypsum, including the manufacture of forms, is absolutely safe and feasible in the most simple terms.

The invention is illustrated by drawings, where figure 1 shows a General view of the molds of the interior-facing products from plaster. Figure 2 - cross section shape, where the 1 - form, made of solid material, 2 - plate (glass, plastic, etc.), 3 - lapping Playground, 4 - side form, 5 - DNAs is Rennie wall forms, 6 - figure bottom of the form, 7 - shaped portion of the clamp plate.

Form 1 is made entirely of material having the properties of antiadhesive, low ekzotermicheskie, high elongation and impact strength and eliminates the division form on the pallet and the matrix, which reduces manual labor in the manufacture of the form, the forming operations, and retrieval of products. Produced in this way products do not require manual handling, as they have strict dimensions. A high degree of strength form completely eliminates the risk of damage to the pressure plate at the time of pressing. The most accessible material for the manufacture of such plates is a silicate glass or homogeneous form of composition.

In the manufacture of products the working volume of the mold can be of any standard and custom sizes and configurations with the presence of convex and concave parts drawings of any complexity. For example, for the product size 120×120×60 with curly walls and shaped outer surface. The proposed form is manufactured as follows:

1. The model, made of any sturdy material, treated with a hydrophobic composition, is placed in the formwork face up.

2. The model poured the substance of cold hardening and leave until completely cured.

<> 3. After 15-24 hours of the prepared extract the model, using warm water, giving the form of elasticity.

It should be noted that the new form at all stages of the phase transformation of gypsum saves the solid state only at the last stage, accompanied by evolution of heat, it is flexible, which allows effortless to extract the finished product. Since the bottom of the form transparent, easily accomplished visual control of all manufacturing processes.

The material from which the molded form is on TO-153-18826195-99, non-toxic and approved for sale, has a large elongation and toughness, practically, is not subject to wear and deformation, which guarantees the durability of the forms and high quality products throughout its operation.

The proposed method of manufacturing art and decorative facing products on the basis of gypsum binding materials, such as lightweight mosaic, with increased hardness of the front surface and the like, as follows:

Dry ingredients: gypsum binder and additives shut water and the resulting solution is poured into a mold, and fill only ½ part of the volume form, distributing the solution over the entire area of the form. This allows free exit of the hcpa what's bubbles the resulting mixing of the solution out. The subsidence of the solution helps to release excess moisture upward. To change the color in the solution can be used harmless food dye and textile industry, then add the second part of the solution to a total amount equal to 3/4 of the volume form, thereby displacing the excess moisture out.

The resulting mass is compacted curly and the presser plate until it stops lapping on the site. To obtain the greatest strength of the surface layer is applied, the average intermediate layer of dry gypsum binder. This allows you to get the thick consistency of the solution used in the formation of as dry plaster absorbs the excess moisture from the previous layer, which excludes the formation of hidden cavities and voids in the process of drying products. Produced in this way, products of higher quality and have compacted, glossy structure of the front surface, which cannot be achieved by previous methods of molding, since the solution of such consistency is virtually netcut. The decrease in the percentage of air and water in the solution has a positive effect on the phase transformation of gypsum in the closed environment of an applied form. After the process is finished, pour the finished product is easily removed from the mold, has a great durability. The consumption of raw materials in this way is else by 15-25% in contrast to the previous method, where quality seal is applied, the excess amount of the solution. Thus obtained product has a smooth, dense surface. Moreover, the back side of the products has four or more mounting pad formed in the result of applying figured plates filled with immersion in the working volume of the shape. After extracting the product is dried in natural conditions. Then on the front surface coated. The monolithic strength of the thus obtained coating based on the uniformity of its composition with the product. A method of manufacturing a coating harmless and entirely feasible in the home, using the ability of gypsum to the rapid hardening under the influence of moisture.
