各种型号的硬质玻璃柱
各种型号的硬质玻璃柱 详细信息：

硼砂和硼酸是火箭、破璃、医药等工业上的重要原料,在玻璃工业上用量尤大,在目前我国国产硼杪和硼酸的供应还未十分充裕的时候,应在大限度内减少硼的进口,并玻璃工业以外,其他工业用硼的需要。因此,进行了改进玻璃质量的研究,要求在璃璃质量、提高其化学稳定性和耐热度的前提下,尽量减低玻璃成份中硼的含量。

玻璃柱尽管有有易碎的缺点，但它具有化学惰性好，制备的柱子柱效高，便于观察柱子情况，使用温度范围较宽等优点，依然被广泛使用。

Various types of hard glass columns
Various types of hard glass columns Details:

Borax and boric acid are important raw materials for rockets, broken glass, pharmaceuticals and other industries. They are particularly used in the glass industry. At present, when the domestic supply of boron and boric acid in my country is not sufficiently abundant, the amount of boron should be minimized. import and guarantee the need for boron in other industries besides the glass industry. Therefore, research on improving the quality of glass has been carried out. It is required to reduce the boron content in the glass composition as much as possible on the premise of ensuring the quality of the glass, improving its chemical stability and heat resistance.

Although glass columns have the shortcomings of being fragile, they are still widely used because of their good chemical inertness, high column efficiency, easy observation of the column conditions, and wide operating temperature range.
