Origin and classification of glass products
Glass cup refers to the cup made of glass. It is usually made of raw material high borosilicate glass and fired at a high temperature of more than 600 degrees. It is a new environmental protection tea cup, which is more and more favored by people. The glass is transparent and good-looking. Compared with other materials, the glass is healthier. Glass does not contain organic chemicals. When people drink water or other drinks with glass, they don't have to worry that harmful chemicals will be drunk into their stomach. Moreover, the glass surface is smooth and easy to clean, so people drink water with glass is the healthiest and safest. In terms of structure, there are generally double-layer and single-layer, and their production processes are different. The double-layer glass is mainly suitable for the needs of advertising cups. Some can be printed with the company's logo on the inner layer to promote gifts or gifts. At the same time, it has the characteristics of anti hot hand, beautiful and fashionable. High borosilicate heat-resistant glass is an excellent anti-corrosion material. The international standard is03585 "performance of borosilicate glass 3.3" is the material standard for making glass chemical equipment, because the linear expansion coefficient of this kind of glass is "3.3 glass". Compared with the traditional sodium calcium glass (thick wall water cup), the molecular structure is more compact, and only a small thickness is required to achieve good seismic and shatter proof effect and strength. High borosilicate heat-resistant glass products usually have a wall thickness of about 1.1mm. They feel light but firm and durable. This kind of glass is called Pyrex in the United States. It was originally invented by Sullivan, a researcher of Corning Glass Company in 1915 and obtained an invention patent. Pyrex is a trademark of Corning products. After the patent of Pyrex glass expired, this kind of glass was widely used in various countries. High borosilicate glass takes borosilicate as raw material, and the instantaneous temperature difference is: - 20 ℃ - 150 ℃. High borosilicate glass has the characteristics of high strength, high temperature resistance, impact resistance, corrosion resistance, rapid temperature change resistance, high transparency and no self explosion. It is more close to life with many advantages, such as acid-base resistance, strong water resistance, high hardness, friction resistance, easy cleaning, not easy to leave stains, and no harmful substances to human body.

The origin of glass products and introduction of new products
Glass is something we often need to use in our daily life, while glass was first invented by Egyptians, and was not introduced to China until the reign of Yongzheng. The cups we drink from today are also different from those used in ancient times. The cups used by ancient people are very different from modern ones. However, in 1990, an artifact from the Warring States Period was unearthed, which changed people's understanding of the ancient cup. It is the Crystal cup of the Warring States Period. Today, we have launched several new products: cartoon cups, sippy cups and Japanese cups.

History and application of high boron glass
The coefficient of linear thermal expansion of high borosilicate glass (also known as hard glass) is (3.3 ± 0.1) × 10-6 / K, also known as "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries. Its good performance has been widely recognized by all sectors of the world, especially in the field of solar energy, which has been widely promoted in developed countries such as Germany and the United States。High borosilicate glass has a very low coefficient of thermal expansion, high temperature resistance and sudden change of temperature difference of 200 degrees. High borosilicate glass is used for reflective heat-resistant lamp cups of halogen lamps and electrical equipment that must use heat-resistant glass, such as glass turntable for microwave oven, microwave oven lampshade, stage light reflection cup, observation window of drum washing machine, heat-resistant teapot, teacup, solar collector tube, etc.

Introduction and advantages of double glass
According to scientists, 65% of the composition of the human body is water, and an adult should drink at least 8 glasses of water a day to meet our normal physiological activities. Therefore, a good water cup is very important for us. A good water cup should not only have a beautiful appearance, but also have a good thermal insulation effect. One good choice is a double glass. We should all know that double glass is a kind of water drinking appliance that is often used in our daily life. Double layer glass is favored by people because of its good heat preservation effect and exquisite appearance. So what are the advantages of double glass? Today, Xiaobian will briefly introduce the advantages of double-layer glass and its cleaning methods. I hope you can gain something after reading it. Introduction to double glass: The concept of double-layer glass is actually very simple. It is a kind of water cup composed of two layers of glass. The double-layer glass is made of food grade glass, which is fired at a high temperature of 600 degrees, so it is non-toxic and harmless to human body. It is especially suitable for people to use as a double-layer insulating glass. Advantages of double glass: The advantage of double-layer glass cup is that it is made of glass. The water cup made of this kind of glass is wear-resistant, and the surface is very smooth. It is easy to clean, will not cause scale accumulation, and is very clean and hygienic. The second is double glass insulation. An ordinary water cup is too hot to carry after it is filled with boiling water. However, the double-layer glass adopts a double-layer design. The inner layer contains water, and the outer layer basically does not feel the temperature. Secondly, the appearance design of this kind of water cup is novel and unique.

Cleaning method of double-layer glass cup: The cleaning of water cups has always been a headache for people, especially for people who often drink tea. But the cleaning of double glass is very simple. First, we can use potato peel to remove tea scale. We put the potato skin in a water cup, add boiling water, keep it stuffy for a few minutes, shake it, and all the tea dirt will be removed. There is also the use of toothpaste and tea washing, which is also a good way to clean double-layer glasses. Or we can use bleach to clean the water cup. The above is the information about the double-layer glass, the advantages of double-layer glass and its cleaning methods introduced by Xiaobian today. I hope it will be helpful to you. Double glass is a kind of healthy and fashionable drinking water. If you need to buy double glass, you can go to the local supermarket or shopping mall.

Types and product shapes of glass
Glass is an amorphous inorganic nonmetallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O · Cao · 6sio2. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to isolate wind and transmit light. It belongs to mixture. There are also colored glass mixed with oxides or salts of some metals to show color, and tempered glass prepared by physical or chemical methods. Some transparent plastics (such as polymethylmethacrylate) are sometimes called plexiglass. Our company mainly produces high borosilicate glass. The main products include teapot, storage tank, tea cup, double-layer cup, cartoon cup, straw cup, candle cup, water cup, wine cup, coffee cup, red wine cup and so on

The first choice for drinking glasses should be glasses, especially for office and home users. The glass is not only transparent and beautiful, but also the most healthy and safe of all materials. The glass is made of inorganic silicate and contains no organic chemicals in the firing process. When people drink water or other drinks with glass, they don't have to worry about chemicals being drunk into their stomach; Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, it is the healthiest and safest for people to drink water with glass. The only thing to note is that the glass is most afraid of thermal expansion and cold contraction. Do not fill the glass with hot water immediately if the temperature is too low to prevent it from cracking.
