(54) METHOD FOR PROCESSING GLASSWARE

(57) The invention relates to the construction industry, to the production of glass products, and is intended to improve the quality of glass products treated with a diamond face, to reduce the consumption of acids used for the chemical polishing of ground glass products. The purpose of the invention is to improve the quality and reduce the consumption of acids during polishing. This goal is achieved by the fact that, prior to grinding glass products, a coating in the form of an oligoorganosiloxane emulsion is applied to their surface. The coating is applied to the surface of glass / edema at 160–200 ° C.

injection-type nozzles Glass products with coatings are machined with diamond tools, and then polished products are treated with alpolishing solutions. At the end of the chemical polishing process, the coating dissolves while maintaining the surface quality. Through the diamond coating on the glass surface, the number of chips on the facets is reduced with diamond tools As a result, fewer acids are required in the subsequent chemical polishing. In addition, the consumption of acids is significantly reduced when processing glass products with coatings due to the fact that most of the surface is protected by the coating from acids, so they are mainly spent on polishing the surface of the faces. In traditional methods, the main amount of acids is consumed on the entire surface of the glassware, the quality deteriorates. surfaces (appears) The formation of a coating on the surface of glassware reduces not only the consumption of acids but also the amount of waste generated during neutralization 1 tab.

The invention relates to the construction industry, to the manufacture of glass products and is intended to improve the quality of glass products treated with a diamond face, reducing the consumption of acids used for the chemical polishing of ground glass products.

The aim of the invention is to improve the quality and reduce the consumption of acids during polishing

PRI me R. At the surface of glass products at 160–200 ° C, an emulsion of oligoorganogldridyloxane is applied by spraying for 5–10 s. The coating is formed within 15–20 min.

For the preparation of the emulsion, use G QOL-94-oligoethylsiloxane of the formula

Characteristics of the processing of glass are shown in the table.

As can be seen from the table, during the formation of a coating on the glass surface, the consumption of acids is reduced by 1.5-2 times, the loss of glass during polishing is reduced, and consequently, the amount of
