Glass has good light transmittance and high chemical stability. According to different processing methods, it can achieve strong mechanical strength and heat insulation effect, and can even change color independently to block strong light, so it can be often used in all walks of life. , To meet various needs, next, let’s take a look at how to prevent the glass from breaking and which glass materials can better heat resistance.
Put the purchased cup in water and heat it to boil to prevent explosion. Do not fill up with hot water immediately when using it in winter. First connect a small amount of water temperature to the mouth of the cup, and then use it to prevent the temperature difference from bursting. The cause of the rupture is the inside and outside of the cup. The temperature difference is large, and the thin-walled cup of good quality is not easy to explode.，glass pot with lid .
　　The glass cup is broken due to uneven heating of the inner and outer walls, and the pressure exceeds the strength of the cup. However, if the small spoon is placed in the cup to bloom with water, the thermal expansion coefficient can be indirectly reduced, and it will not fry.
Double-layer glass
　　What kind of glass material is more heat-resistant?
Heat-resistant glass (contains boric acid and silicic acid components with strong heat resistance, special glass that can withstand the temperature difference of cold and heat It is easy to break and has a variety of excellent properties such as low expansion, heat resistance, high temperature resistance, corrosion resistance, and high strength. The commonly used heat-resistant glass containers are mostly high borosilicate materials. High borosilicate glass uses glass to conduct electricity at high temperatures. The characteristics of the glass are melted by heating the inside of the glass and processed by advanced production technology.
The price of raw materials is higher than that of ordinary glass, and the manufacturing cost is also higher. Therefore, the selling price of heat-resistant glass is higher than that of ordinary glass and tempered glass. The heat temperature reaches 1200, so there will be no explosion like tempered glass. Heat-resistant glass is mostly used in bowls, baby bottles, experimental beakers, industrial boiler goggles, mechanical equipment glass, double-layer glass, etc.
