Abstract

FIELD: building unit production, particularly to manufacture reinforced concrete, cement-sand and ceramic materials and articles of said materials (blocks, tiles, bricks and so on).

SUBSTANCE: method involves applying layer including glassy granules with 3-5 mm particle dimensions on building article surfaces and fusing thereof. The layer is formed of broken glass sheets and broken glass color filters taken in proportion of 8:2. Low-melting and high-melting glass granules have different colors.

EFFECT: improved article quality.

Description

The invention relates to the production of concrete, cement-sand, reinforced concrete, lime-sand, ceramic materials and products (blocks, tiles, bricks, etc.).

A known method of finishing construction products, in particular concrete and cement-sand, by applying to their surface a layer of glassy granules of different colors with subsequent melting [1].

There is also a method of finishing building products by applying to their surface a layer of glassy granules with subsequent melting [2]. In this method, glassy granules are treated with dye glass. The disadvantage of this method is the use of liquid glass, the high-temperature processing of which can lead to defects (bubbles, swelling) on the surface of the products.

The objective of the invention is to improve the consumer qualities of products.

The technical result is achieved by the fact that according to the method of finishing building products by applying a layer of vitreous granules to their surface with subsequent melting, the layer includes 80-98 wt.% Low-melting and 2-20 wt.% Refractory vitreous granules, and the fusion temperatures of low-melting and refractory vitreous granules differ by 200-400 ° C. Fusible and refractory glassy granules have a different color.

The method is illustrated by the following example.

Low-melting and refractory glassy granules are mixed, for example, fractions of 3-5 mm, in ratios, wt.%:

1) fusible (window glass break) glassy granules 80 and refractory (glass filter breaks) glassy granules 20;

2) fusible (glass container fight) glassy granules 85 and refractory (electric vacuum glass fight) glassy granules 15;

3) fusible (high-quality glass break) glassy granules 90 and refractory (light-glass break) light-glass granules 10;

4) fusible (medical glass fight) glassy granules 98 and refractory (chemical-laboratory glass fight) vitreous granules 2.

Glassy granules are applied to a horizontally located surface of products, such as concrete, and are fixed by reflow. In this case, bubbles and swelling on the surface of the product is not formed. The glassy coating on the product is even, with prominent decorative (non-melted) inclusions, and in the case of the use of glassy granules of different colors - a variety of color tones. This technical solution improves the consumer quality of products.
