What is the difference between high borosilicate sight glass and ordinary sight glass
As a new product in the sight glass, the sight glass has become the best drinking tea tea, tea sparkling light, not suitable for tea and enjoy the best effect. The sight glass is very cheap and good, and it is well received by the broad consumers. The sight glass has the following advantages:
1, material: the cup body is processed with excellent high boron silicon crystal sight glass tube, with high brightness, wear-resistant, lubricated appearance, clean and clean, healthy and clean.
2, technology: after 640 degrees of high temperature burning, the adaptability of the temperature change, the temperature difference is -20 - 150 - C, not easy to burst.
3, clean: food grade standard, can be filled with 100 degrees of hot water, tea, carbonic acid, acid and other drinks, resistant to malic acid corrosion, no taste without taste.
4, leak proof: the inner outer layer and seal ring of the cup cover medical grade safety standard, effective leakage prevention.
5, suitable for tea: green tea, black tea, Pu'er tea, flower tea, technical flower tea, fruit tea and so on, the soup color to the bottom of the eye, to improve the quality of life.
 
The primary ingredients of the sight glass are crystal sight glass, sight glass and high borosilicate sight glass and so on. So what do these raw materials have in the end? Here is a brief introduction to you.
Crystal sight glass is called artificial crystal, because the sparsity and unbrief exploitation of the natural crystal can not satisfy the needs of everyone, and the artificial crystal sight glass is born. Crystal sight glass is cooked and dissolved together with sand and lead oxide. The advantages of the use of lead is heavier, texture, more transparent, clear and bright; the downside is relatively soft, easy to wear flowers, so more is not necessarily better lead. However, modern people are more and more aware of the concept of environmental protection, so that the production of crystal sight glass also infiltrated into the environmental elements. The new lead-free barium free crystal sight glass is extremely elastic and crystal clear, and is more safe than the crystal sight glass.
 
The main ingredients are usually sight glass silica sight glass hard and brittle texture, is a colorless, transparent, and can add a variety of components made of tinted sight glass, light brown sight glass, cobalt blue sight glass etc..
Usually sight glass after heat treatment can be made of toughened sight glass, its elasticity, impact resistance and thermal stability is better than that of common sight glass, with high mechanical strength. The new transparent toughened sight glass to be higher than the common sight glass is 4~5 times as crystal clear, usually charming, with it also has high hardness and high temperature resistant properties.
 
In 1893, high borosilicate sight glass, Otto Short (Otto Schott) invented a chemical corrosion resistant borosilicate sight glass. Is a kind of sight glass with sodium oxide, boron oxide and silica as the basic ingredients. The content of borosilicate in this sight glass is high, which is boron: 12.5~13.5%, silicon: 78~80%, so this kind of sight glass is high borosilicate sight glass.
 
The high borosilicate sight glass has very low thermal expansion coefficient, high temperature resistance and 200 degree temperature difference. High boron silicon sight glass used for reflecting heat lamp halogen lamps and electrical equipment to use heat-resistant sight glass, such as microwave oven, microwave oven turntable special sight glass lampshade, stage light reflecting cup, drum washing machine observation window, sight glass teapot teacup, solar collector etc.
