Problems solved by technology

[0002] Glass is a glass instrument commonly used in chemical laboratories. It is used at room temperature or under heating; no matter what kind of glass has corresponding usage specifications, if it is not used according to the usage specifications, it is easy to cause damage to the glass
One of the main causes of damage to the glass is that it is broken by an external impact. Another more common reason is that the glass burst due to uneven heating during the heating process.
[0003] The easy damage of the glass is not only due to improper operation, but also the nature of the glass material. The impact resistance of the glass material is relatively poor, and the uneven internal stress will cause the glass to explode.

Abstract

The invention provides a temperature difference resistant glass cup and a preparing technology thereof. The temperature difference resistant glass cup is prepared from, by weight, 55-65 parts of nano-silicon dioxide, 5-10 parts of nano aluminium oxide, 4-8 parts of magnesium oxide, 0.2-0.6 part of lithium oxide, 7-12 parts of calcium fluoride, 0.5-1 part of zinc oxide, 0.3-1.5 parts of ferric oxide, 3-5 parts of phosphorus pentoxide, 6-10 parts of cerous nitrate, 0.5-2 parts of germanium powder, 0.2-0.5 part of neodymium sesquioxide, 0.5-1 part of zirconium sulfate, 1-2 parts of silicon carbide and 5-11 parts of a modifying agent. By the adoption of the preparing technology, properties such as the rupture strength, cracking resistance and thermal stability of glass are improved, the glasscannot crack when exposed to large change of the temperature difference, and thus the glass cup has high temperature resistance, good smoothness and high abrasive resistance.

Description

technical field [0001] The invention relates to the technical field of glass, and specifically discloses a temperature-difference-resistant glass cup and a preparation process thereof. Background technique [0002] Glass is a glass instrument commonly used in chemical laboratories. It is used at room temperature or under heating; no matter what kind of glass has corresponding usage specifications, if it is not used according to the usage specifications, it is easy to cause damage to the glass. One of the main causes of damage to the glass is that it is broken by an external impact, and another more common reason is that the glass burst due to uneven heating during the heating process of the test tube. [0003] The easy damage of the glass is not only caused by improper operation, but also due to the nature of the glass material itself. The impact resistance of the glass material is relatively poor, and the uneven internal stress will cause the glass to explode. Contents of...
