RU1812177C - Method for decorative machining of carbonate stone - Google Patents

Abstract

Usage: in the production of building materials for the decorative processing of carbonate sawn stone. SUMMARY OF THE INVENTION: Acid resistant enamel is applied to the surface of a carbonate stone according to a predetermined pattern, the surface is treated with acid, washed with water and the enamel layer is dissolved, then the surface of the stone with the obtained relief is washed off successively with a 10% solution of washing powder Universal-M and distilled water.

Description

The invention relates to a technology for processing building materials, in particular to the surface treatment of stone products and can be used for decorative processing of carbonate stones.

The purpose of the invention is to obtain a relief image on the surface of carbonate stones with constant properties over time.

A comparative analysis of the claimed solution with the prototype shows that the claimed method differs from the known topic. that after treatment with acid, water and a solvent, the reaction products adsorbed on the treated surface are washed off with a 10% solution of universal Universal-M washing synthetic powder with distilled water.

A technological solution is known which consists in machining stone using mechanisms and manually.

However, this method requires the expenditure of mechanical energy of manual labor and the process takes a long time.

Improving product quality is achieved by washing detergent solution and water off the surface of the reaction products.

Example. A plate sawn from Yenokovan marble is wrapped around the side faces with a polymer electrical insulating tape so that the edge of the insulating tape is at the level of the surface to be treated. An AC 1115 grade gray enamel is applied to the surface. The plate is placed in a polyethylene bath with the surface to be processed down on supports in the corners and a solution of hydrochloric acid (obtained by diluting concentrated acid with water in a volume ratio of 1: 1) is poured to the level of the required relief depth.

The duration of the process at a depth of 1 mm is 5 minutes, the flow rate of the solution is 0.25 l per 1 m2 of slab. After the process, the stove is washed with water; processing time 0.1 min. Enamel from the plates is washed off with acetone, after which the surface is washed with a 10% solution of washing powder synthetic Universal-M, distilled water. The output of the plates at the surface treatment stage is 100%. After repeated processing of the acid solution, the accumulated solution in the bath is evaporated at room temperature and calcined in a muffle furnace, thereby obtaining technical anhydrous calcium chloride, which can be used as a cheap desiccant in various technological processes.

With a mixture of technical and waste acids (e.g., technical acetic acid from a chemical chemical industry), the process is carried out in a similar manner.

SUMMARY OF THE INVENTION A method for decorating carbonate stones, including applying acid-resistant enamel to a surface according to a predetermined pattern, treating with acid, rinsing with water and dissolving the enamel with an appropriate solvent, which is distinctive and so as to obtain a relief pattern with constant properties over time, after the enamel dissolves, the surface of the stone with the obtained relief is washed off successively with a 10% solution of Universal-M washing powder and distilled water.
