1. What is a double-walled borosilicate glass bottle?

The raw material of the double-walled glass bottle is high borosilicate glass, food-grade catering-grade glass fired at a high temperature of more than 600 degrees. It is usually made of high-borosilicate glass tubes. It is a new type of environmentally friendly tea bottle, which is increasingly popular among people.

2. Does a double-walled glass bottle really keep warm?

Many people have such experience. When using a disposable bottle to receive very hot water, they often use two paper bottles to hold it, so that it is not hot. This is the most primitive thermal insulation bottle. So is the double-walled glass bottle insulated?

The double-walled glass bottle was first invented by the Japanese in the last century. First, the double-walled bottle wall was made, and then the air in it was evacuated so that the hot water in the inner stainless steel bottle could be kept in its original state when it was evacuated. Water temperature, such a bottle not only keeps warm but also keeps the wall of the bottle at a low temperature, so that we will not be heat-conducted by high temperature when using it, which is convenient for drinking water.

Since the double-walled glass bottle is double-walled, it must have the function of heat insulation. The double-walled glass installed on the floor-to-ceiling windows of many high-rise buildings plays the role of heat insulation and noise isolation.

Of course, this double-walled glass bottle is slightly less functional than an actual thermos bottle, because its compartment is not a vacuum. If this compartment is evacuated, and then the inner -wall is plated with mercury, it becomes a traditional thermos bottle, and the thermal insulation effect is very good, but the aesthetic effect is far from good.

Therefore, this double-walled glass bottle now takes into account both the appearance and the thermal insulation function, and the appearance is the first priority.

1) Material: The bottle body is made of high-quality borosilicate crystal glass tube, with high transparency, wear resistance, smooth surface, easy cleaning, health, and hygiene;

2) Structure: The double-layer heat insulation design of the bottle body not only maintains the temperature of the tea soup but also does not get hot, making it more convenient to drink;

3) Process: It is fired at a high temperature of more than 600 degrees, which has strong adaptability to temperature changes and is not easy to burst.

4) Hygiene: Food grade standard, can hold hot water, tea, carbonic acid, fruit acid, and other beverages at a high temperature of 100 degrees, resists the erosion of malic acid, and has no peculiar smell or odor.

5) Leak-proof: The inner and outer layers of the bottle cover and the sealing ring meet medical-grade safety standards and are effectively leak-proof.
