1, and high temperature resistant glass does not heat two material points. Does not heat the glass temperature is generally "5 to 70 degrees Celsius," if it is made of a high temperature borosilicate glass material, then it may be a high temperature 400 to 500 degrees, and can withstand moment "- 30-160 degrees Celsius, "the temperature difference.

  

2, whether the difference between the glass and heat-resistant material, is very simple: the surface temperature is the glass are not hot water, not high temperature by the glass surface is hot water.

  

3, ordinary glass

  

ordinary glass material is a poor thermal conductor, when suddenly a portion of the inner wall of the glass when exposed to heat (or cold), the inner cup is heated significantly expanded However, the outer layer not expanded less heat, whereby the temperature difference between parts of the glass, and thermal expansion and contraction causes an object, thereby to make portions of non-uniform thermal expansion of the glass, this uneven when the difference is too big, it can make the glass shatter.

  

Meanwhile, the glass is very rigid material, the heat transfer is slow, the thicker the glass, due to the effects of temperature, the temperature rise rapidly when the easier burst. That glass of water with the temperature too much causing the glass burst. Therefore, the use of thicker glass temperature is generally "-5 to 70 degrees Celsius," or before the first pour boiling water add a little cold water, add some hot water, and other warm cup after the water drained, plus water, no problem.

  

4, the maximum temperature characteristics of borosilicate glass comprising a glass having a very low coefficient of thermal expansion, approximately one-third that of ordinary glass, which is insensitive to temperature, no thermal common general object shrink expansion, which has a high temperature, high thermal stability. It can be used to hold water. However, do not be tempered as the market does not use high-temperature glass, tempered glass and ordinary glass cupThe temperature is the same, generally 70 degrees or less, you need to use caution. And some experts said that does not yet exist so-called heat-resistant glass products or tempered heat-resistant glass products on the domestic market, do not be misled at the time of purchase. If the heat-resistant glass, usually affixed to the cup respective marking, indicate the use of temperature (temperature for example 150 掳, and of course of boiling 100 掳), other range; best to develop in the purchase look marking the habit, but found that heat-resistant glass nominal price is very low, to consider its authenticity.

  

2020-06-05 small series of glass will explode when you install hot water for a simple introduction, if you want to learn more about it and other small glass of toxic knowledge also please pay attention to home security Tips , I hope this helpful to you.
