A kind of glass used for fireplace and bonfire decoration and preparation method thereof

Abstract

The invention provides glass for fireplace and bonfire decoration and a preparation method of the glass. The glass for the fireplace and bonfire decoration is high borosilicate glass, the high borosilicate glass is of polygonal grains, and the distance from any one point inside the polygonal grains to the nearest surface is equal to or less than 10mm. According to the glass provided by the invention, the high borosilicate glass is taken as a raw material, stress inside the glass is reduced through controlling the shape and size of the glass, airflow among the grains during combustion is promoted, temperature conductivity is accelerated, temperature difference is reduced, and cracks are prevented. The experimental result indicates that the glass for the fireplace and bonfire decoration can be directly paved on a combustion tube of a fireplace or bonfire to ignite (the highest flame temperature is 800 DEG C), the fire is extinguished after burning for 30 minutes, no cracking sound appears in the whole process, and damages and cracks do not happen.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a glass used for fireplace and bonfire decoration and a preparation method thereof. Background technique [0002] In the classical fireplace and bonfire culture, wood is generally used for heating and decoration to create a warm atmosphere; but most modern fireplaces and bonfires have been converted to gas burning, and simulated wood made of refractory materials is used instead of real wood. To decorate and create the effect of classical fireplaces and campfires. Some new styles of fireplaces and bonfires are popular now. Some use crushed tempered glass particles, and some use ordinary soda-lime glass particles. They are laid on the fireplace or bonfire chassis, and the gas flows out and ignites through the holes on the bottom plane or the trachea. , flames burn on these decorative pieces of glass or pellets for a one-of-a-kind effect. [0003] There are many disad...

AI Technical Summary

Problems solved by technology

[0003] There are many disadvantages when ordinary glass particles are used for fireplace and bonfire decoration: because the fireplace will cause a local high temperature difference in the glass particles when the fireplace is ignited and burned at a low temperature, the temperature difference is about 200-300°C in a short period of time, while ordinary soda-lime glass is resistant to The performance of rapid cooling and rapid heating is poor, and the temperature difference is 80°C, so some particles will burst during use, which will bring danger; and, due to the low temperature resistance of ordinary glass, it is easy to powder, crack and pulverize locally after long-term use. The debris will fall to the ground from the air hole or the water hole, which poses a safety hazard

[0004] Tempered shattered glass particles also have obvious defects when they are used for fireplace and bonfire decoration: broken tempered granules have more sharp fractures (cutting edges), and there is a risk of laying; If it falls to the ground in the air guide hole or the water flow hole, there is a safety hazard

However, the temperature difference of high borosilicate glass is 280°C, and there is still a risk of bursting when the fireplace is ignited and overheated.
