Abstract

The invention relates to methods for producing ceramic facing products. In order to improve the quality of products by completely eliminating efflorescence and preserving the natural color while reducing the cost, a protective coating is applied to the molded timber based on the waste of coke production, including acidic tar and vat residue of benzene rectification in a ratio of 70-94% by weight and 6-30 wt.% respectively, followed by drying and firing. 1 tab. about € (L G tvD CO a: ate 4:

Description

one

The invention relates to the building materials industry and can be used to preserve the natural color of the shard of ceramic facing products, for example, facing brick.

The purpose of the invention is to improve the quality of products by completely eliminating efflorescence and preserving the natural color while reducing cost.

Acid tar is a waste from coke-chemical production and is a mixture of thiophene alkylation products and benzene hydrocarbons, additive polymers, homologues of benzene (65-75%), sulfuric acid (.to-150%), water (10-15 %) entrained hydrocarbons (5-10%). Acid tar - in a liquid zakhe12965472

respectively. As a result, the required viscosity of the film is formed for the application of its solution. Then, the prepared solution is put on the surface of the extruded bar, cut the bar into individual products, dry them (the layer of solution prevents the evaporation of water from the front surfaces of the product and the appearance of efflorescence) and after

10 of this is burned. Drying and firing are carried out according to known regimes. When using Sigi, the solution completely burns out from all surfaces of the brick, including those in contact in the load.

 5 Example. Acid tar and distillation residues of benzene at 20 ° C are mixed to obtain a homogeneous liquid in a ratio, wt.%: Acidic tar 80; bottoms

liquid non-flammable. The cubic residues of benzene distillation are also a waste of coke production, are formed during the final distillation of the washed benzene fractions and consist of products of different polymerization depth of unsaturated compounds, their copolymerization with the benzene hydrocarbons of the North Round by plastic method form a bar and cover its faces with a solution , at the same time the solution consumption is 3-6 liters per TOOO pcs. CONDITIONAL Bricks. The timber is cut into bricks, which are dried at. When drying on the edges of a brick, a moisture-proof film is formed, which helps to preserve the natural color of the brick.

Then, as well as thermal polymer 30, the brick is then calcined at 1000 ° C, unsaturated compounds (styling from all faces of the brick, roll and its homologues) and various mines, including contacting in the charge, of impurities. This waste is a moving dark brown liquid with a strong odor. 35 efflorescence.

An acidic tar and a bottoms residue are taken from the rectification of benzene in the natural state and mixed in a co-40 and bottoms rectification in a bent ratio of 70-94 wt.% And 6-30 wt.%
