Compound de-foaming agent suitable for bottle ware glass production

Abstract

The invention discloses a compound de-foaming agent suitable for bottle ware glass production. The compound de-foaming agent mainly comprises a main component and a solvent component, wherein the main component comprises a foam breaker composed of titanium compounds, a foam wall thinning agent composed of sodium nitrate and potassium nitrate and a solvent combustion efficiency optimizer ferrocene; the solvent component contains diesel oil, aviation kerosene, heavy oil or mixture thereof at any ratio; the flashing point of the solvent is at 38 DEG C or above; and the main component is dissolved in the solvent or is suspended in the solvent in a sold particle state. The compound de-foaming agent disclosed by the invention can form new small bubbles on a floating molten glass bubble wall so as to achieve the function of thinning the foam wall, and meanwhile, can boost the foam breaking in the manner of reducing the local viscosity and surface tension of the bubble wall so as to accelerate the breaking of bubble layers on the molten glass surfaces in different temperature areas of a kiln without increasing the highest temperature of a bottle ware kiln, so that the foam discharging efficiency of the molten glass can be increased, and the influence of the bubble defects of the bottle ware glass can be reduced.

Description

Technical field

[0001] The invention belongs to the technical field of melting during the production of bottle and container glass, and more specifically relates to a composite defoamer suitable for the production of bottle and container glass. Background technique

[0002] In the production process of bottle and container glass, CO will be released due to the high temperature decomposition and melting of raw materials such as silica sand, feldspar, soda ash and nitrate. 2 , NO / NO 2 , H 2 A large amount of gas such as O forms a large number of bubbles in the glass liquid. The bubble layer almost covers the non-material covered area in the glass furnace of bottle and container. The thickness of the bubble layer is 10mm-100mm. At the same time, because the glass of bottle and container usually has There are colors, such as green or brown beer, blue glass bottles for oral liquids, etc. The use of colorants causes the temperature gradient of the glass liquid in the depth direction to ...

[0037] A composite defoamer suitable for the production of bottle and container glass, including the main components and solvent components, each specific composition, defoaming effect, and the temperature of the molten sample. The starting temperature and target temperature points in the process system are shown in Table 1. Show.

[0038] In order to confirm the influence of the composite defoaming agent of the present invention on the defoaming effect of bottle and container glass, the composite foaming agent of each embodiment was slowly continued in small amounts under the same conditions for different bottle and container glass melt samples under the same formula Inject into a special sample melting furnace, after the same cooling process, cool to room temperature, observe the residual amount of bubbles at the end of the molten sample. The specific process is as follows:
