Organic simulant conforming to high-temperature viscosity gradual change characteristic in inorganic glass

Abstract

The invention discloses an organic simulant conforming to a high-temperature viscosity gradual change characteristic in inorganic glass. The organic simulant is an organic mixture formed by heating rosin, EVA (Ethylene Vinyl Acetate) resin and terpene resin. The organic simulant conforms to the high-temperature viscosity characteristic rule of inorganic glass (a simulated object) and is consistent with the temperature-viscosity trend rule of the simulated object, and the organic simulant has the temperature viscosity characteristic consistent with the temperature of 900-1700 DEG C of the simulated object at the temperature of 200 DEG C or below; the simulant can be used for carrying out melting clarification and feeding forming research on a simulated object (inorganic glass such as soda-lime glass, aluminosilicate glass, borosilicate glass, substrate glass, microcrystalline glass and low-boron glass), and equipment design and production process guidance can be provided for glass production.

Description

technical field [0001] The invention relates to the technical field of inorganic glass, in particular to an organic simulant conforming to the high-temperature viscosity gradient characteristic of inorganic glass. Background technique [0002] The invention of inorganic glass has a long history of 5,000 years and has greatly promoted human civilization. From the early days of soda-lime glass and lead glass to manufacture craft glass for decoration, it has developed to daily-use glass, optical glass, electronic glass, and medical glass made of borosilicate glass, aluminosilicate glass, phosphate glass, and quartz glass. , information glass, display glass, energy glass, transportation glass, aerospace glass and other industrial glass era, glass materials and products meet the development needs of all walks of life. Inorganic glass has developed rapidly in the past 200 years, which has promoted the development of global economy, culture and technology. [0003] At present, in...

Problems solved by technology

[0007] As early as 1932, Flint and Lyel used water, vegetable oil and paraffin as simulation liquids to study the glass kiln by observing the convection effect of the density of the simulation liquid as the temperature changes. However, the miscibility of water, vegetable oil and paraffin is poor. , does not meet the uniformity requirements of the simulant; in addition, the viscosity range of the simulant liquid is relatively narrow, only in the liquid state of 10 poise to 100 poise, and the continuous variation range of the viscosity of the simulant required for simulation research should be 10 poise to 10,000 poise, even to 1 million poise; therefore, this simulated liquid does not have the ability to meet the continuous solid-liquid-solid process of glass manufacturing

In 1933, Schild used glycerin as the simulation liquid to simulate the wear and erosion of the refractory brick surface of the kiln. The simulation work provided useful guidance for the actual kiln design and improvement. Within the range, the viscosity ranges from 20.0 poise (20°C) to 0.4 poise (80°C), which is too small compared to the glass clear viscosity value (100 poise to 200 poise), and does not show a particularly obvious viscous state

In 1968, Safaih used glycerol plus lithium chloride as a simulated liquid to study bubbling in molten glass. The viscosity of the simulated liquid was only 30% higher than that of glycerin alone, and the maximum viscosity was less than 30 poises. The viscosity was still very small and the viscosity range was still small. Very narrow, has the same disadvantages as the previous two documents

[0010] 1. The viscosity range is narrow, and the general viscosity range does not exceed 2 orders of magnitude, that is, 0.1 poise to 10 poise, or 1 poise to 100 poise, or 10 to 1000 poise, or 100 poise to 10000 poise, which cannot cover glass production from batch materials solid-melting clarified liquid-solid complete manufacturing process of molded products;
