SU590308A1 - Method of decorative working of surface of cellular concrete articles - Google Patents

Description

one

The invention is adapted to the methods of decorative processing of cellular concrete products and can be used in architecture, schooling and construction materials.

The method for finishing glaze of products made of lightweight concrete is known, including the application of glaze on the product and the subsequent melting of 750-770 0 1.

Closest to the invention in technical essence and the achieved result is the method of decorative surface treatment of cellular concrete products by applying a dye-based aqueous solution of salt and melting with an open flame, for example, an oxygen-acetylene torch surface 2.

The known methods do not allow to obtain a vitreous film on the entire surface of the product at the same time. In addition, when treating with a gas burner due to a sharp temperature change, microtreiipty are formed on the surface.

The purpose of the invention is to accelerate the process and to obtain a uniform product surface.

This is achieved by the fact that the melting of wasps1, is melted for 1-2 minutes in an oven at 1250-1350С.

Example 1. A brush of salt is applied to the surface of a celled-concrete product with a brush, for example cobalt sulfate 36% 2

sing concentration. The thickness of the salt layer is 0.4-0.8 mm. After the layer of salt dries, the product is placed in the flame of a fuel oil with a temperature. After expiry of 1.min, the article is taken out of the river. In order to avoid the attachment of the product to the metal floor, a gasket of dry peproptanum cellular concrete is placed between them.

Example 2. To obtain thick glasses:: a single ileic on the surface to be treated. Product content: 36% -Hbiii aqueous solution of cobalt sulphate. Tolpgina at a layer of 0.8-1.2 mm. After the layers of salt have dried, the product is placed in a flame of an azut furnace with a temperature of 1350 ° C. In the course of 2 min, the product is removed from the SPP.

The products treated with furnace furnace are more durable, lacking the microchip on the ethereal surface, because unlike the flame of a gas burner, the furnace flame creates a simultaneous effect on the entire surface of the product, which creates the same temperature.

The use of I15 is laid down in the first way. There is a color-coagulation process; Films are 20 times higher than in comparison with the well-known ones. Processing ize4n flampe iie4n allows to obtain a uniform

op; 1 the texture over the entire surface of the product. 34
