Description

Vessel for liquids

The utility model relates to the glass industry, glass containers are known that are used for packaging food liquids of wine, cognac, beer, juice ...) and perfumes. (1) The goal is to increase the mecanic value of glass containers and increase light-protective properties.

This goal is achieved by the fact that the outer side of the surface of the vessel has a coating of fibers of various colors with a base of adhesive composition.

In fig. 1 shows a glass vessel, on the outer side 1 a coating 2 of which the adhesive is the basis. No layer of glue is deposited on the surface of the vessel; for example, it uses the adhesive composition PBC-plastisol or PVA-emulsion. Then, by the method of electro-Flocking, fibers of polyamide, polyester or viscose pile are applied onto the uncured surface of the adhesive composition with a layer of 0.6 mm, 8 mm, fiber length y, 3 - 0.5 mm. After drying for 20 min at a temperature of 170 degrees, a dense pile coating is obtained.

When creating a Flocked surface, part of the villi, the number of which depends on the electrical properties, on the electrophysical properties of the pile and glue, does not penetrate into the glue and does not recharge when colliding with previously fixed fibers. Also, the fibers remain lying on the Flocked surface and are thoroughly cleaned. A vessel coated with fibers has the following advantages:

- provides sufficient mechanical strength of the vessel;

- the contents are protected from exposure to ultraviolet rays, which helps to preserve the taste and bouquet in drinks.

- vessel slip decreases, which is important for packaging processes; -allows you to receive vessels with a wide range of colors;

Glass has nano- and micro-submicroscopic defects, which determine the mechanism and peculiarity of its destruction (strength). The appearance of surface defects on glass is caused by the influence of structural and chemical inhomogeneities, foreign inclusions and summicroscopic crystallite formations, as well as negative effects

temperature gradient r. The greatest influence on the state of the surface of glassware has its contact with the environment.

at 65 fl

As a result of such contact with solids, abrasive particles and surface-active substances, glass accumulates on the surface foci of brittle fracture-microcracks with a wide degree of opacity "

A large destruction of glass under the influence of external forces begins from its surface as a result of the formation and growth of microcracks. As a result of the contact of the sprayed fibers with the glass surface, a protective coating is created that excludes the appearance of new defects and reduces the softening effect of microcracks existing on the glass surface.

The mechniam of the strengthening effect of the protective coating of fibers is as follows I

- Firstly, the water-repellent ability of the glass surface is increased. Such hydro-glassing of glass reduces the softening effect of surface-active media and, above all, air moisture;

- secondly, the surface of glass bottles is protected from inducing brittle foci (ego of destruction of microcracks, i.e. the glass surface is preserved

thirdly, the stress concentration decreases under destructive mechanical loads, i.e. acts as a protectant. The coating strengthens the glass by 2-3 times.
