What should I pay attention to when using a glass?

Introduction: What should I pay attention to when using a glass? The glass is a relatively safe drinking tool, but the glass is more fragile, before using the glass, the glass should be placed in warm water and cleaned with a cotton cloth, it is easy to burst when encountering high or low temperatures, when pouring water, you can pour a small amount of water, shake the hot water a few times, let the hot water and the inside of the glass fully contact, preheat it, and then pour in hot water, so as to avoid the cup bursting and accidents, the temperature insulation performance of the glass is relatively poor, do not touch it with your hands after pouring hot water, so as not to be burned, Pay attention to safety when drinking water from a glass and handle it gently.

After a long period of use, the inside of the glass will produce heavier tea scale, at this time, you can pour a small amount of baking soda powder and soak it for a period of time and rinse it with water to make it as bright as new, the outside of the glass can be directly cleaned with mild detergent and cotton cloth, and every part of the glass should be cleaned after each use.

1. How to choose a glass.

When buying glasses, it is necessary to observe that the workmanship of the glass can not be rough, there can be no impurities, and the glass can be very pure, and see if there are potential cracks in the body of the glass, if there are cracks, such a cup can not be used for a long time, it is not recommended to choose, to buy some glasses with constant temperature and thickness, otherwise it may explode when pouring boiling water, and finally pour the water in, cover the lid and try the tightness of the cup mouth, if it leaks, don't buy it.

2. Conclusion. It is not easy to choose a glass of qualified quality, there are some people who like to paint colored glasses, colorful ones look very beautiful, but beautiful things are not necessarily safe, this kind of glass coated with pigments is not recommended to choose, the pigments inside will contain some heavy metals, long-term use of such cups, drinking water will cause certain harm to the human body, try not to use. If you want to choose a glass of acceptable quality, it is recommended to go to a regular shopping mall or supermarket to buy it.

In the process of use, you must pay attention to the water temperature, just boil your water and never pour it into the glass to avoid causing the glass to burst, and then when you use it for the first time, you must disinfect it with hot water, and you must wash the cup more often, in order to avoid impurities, you must choose a glass with a lid, and you must test the temperature in advance when you take the cup.

The glass should be placed in a warm place when used, the glass should not be connected to hot water immediately after it is frozen, otherwise it will be **, you should be careful when using the glass, do not bump into it, and clean it up in time after use, and it is best to use the glass to receive warm water.

When using, you must pay attention to the thickness of the glass, you must pay attention to safety issues, you need to pay attention to cleanliness and hygiene, pay attention to cleaning problems, so that you can use it better, you must pay attention to the pattern of the glass, and pay attention to whether there is a broken place.

Be sure to pay attention to the water temperature, but also pay attention to the thickness of the glass, pay attention to the glass cracking, disinfect regularly, and when cleaning, you must pay attention to the method, do not use hot water to clean.

The water temperature should not be too high, do not put it directly in the microwave, do not put cold water in a high-temperature glass, do not scratch the glass with stones, do not put radioactive substances, you should pay attention to these things.

Because the glass is easy to burst when encountering high or low temperatures, it is recommended not to pour cold water from a high-temperature cup or pour hot water from a cold cup when pouring water to avoid accidents due to the explosion of the cup.

In addition, the temperature insulation performance of the glass is poor, so don't touch it with your hands immediately after pouring hot water, as it can be burned.

There is also when saving and moving, try to pay attention to safety, handle gently, the glass is fragile, and be cautious to avoid accidents.

How to choose a glass.

1.A glass with a high quality of transparency should be clear and transparent, with no significant color.

2.Look at the bubbles: The wall or bottom of a high-quality glass is free of bubbles or there are a few bubbles.

3.Look at the roundness of the cup mouth, the high-quality glass has a round and smooth cup mouth, and you can use a book to touch the cup mouth when you choose the glass.

4.See if the body of the cup is tiltedThe body of the high-quality glass is horizontal, and we can look at the glass at level, so that it is easy to see whether the body of the glass is tilted.

In daily life, many people feel very thirsty after taking a shower, and then they will pick up the glass and drink the water in the glass in one go, which is a mistake that everyone is prone to make.

Professional doctors have said that when the gastrointestinal blood vessels are in a constricted state after exercising or taking a hot bath, the gastrointestinal blood vessels need a recovery process. In this case, if you drink a lot of water immediately, the water will accumulate in the gastrointestinal tract, which will cause the stomach to distend, which will affect the person's digestion.

So what is the correct way for people to drink water after exercising or after taking a hot bath?

The correct way to drink water is to take a few minutes after exercising or taking a hot bath, wait for the heart to beat a little steadily, and then take a glass of water and then take small sips of some warm water. In addition, when drinking water, try to keep the speed of drinking water as smooth as possible, so that the frequency of drinking water is best close to the frequency of the heartbeat, and then drink it intermittently and several times.

In this way, the heart can absorb the newly added water in the body regularly and smoothly.

The first time you use the glass, please use a soft cloth and warm water to clean it, if you use it for a long time, the inner tank will produce heavy tea scale.

, a small amount of 84 disinfectant can be poured in.

After soaking for a period of time, rinse with water to make it as bright as new, and clean the outer surface directly with mild detergent and soft cloth.

Each part must be cleaned after each use, please clean it with a mild neutral detergent, in order to avoid scratches on the cup body affecting the appearance, do not wipe the cup with rough metal wool balls, etc.

Glasses are prone to burst when filled with excessively hot or cold water, so avoid using an environment with excessive temperature differences. Usually a temperature difference of more than 80 degrees will cause the glass to expand and contract strongly.

It is easy to cause explosions. Unless otherwise specified, try to avoid using a glass with excessively hot or cold water.

The glass is afraid of bursting caused by boiling water when it is used for the first time, so you should first enter a little hot water and gently shake it to preheat the cup, and then pour the tea after pouring the water.

Generally, put it in water to boil it first, but it is not necessary in summer, and in winter you can ensure that the temperature of the cup is about the same as the temperature of the water, otherwise it will break.

OK. There are several types of utilization of glass products: as a flux for casting, transformation and utilization, refurnace reengineering, raw materials and reuse.

1. As a flux for casting.

Cullet can be used as a flux for the melting of cast steel and cast copper alloys, covering the melt to prevent oxidation.

2. Transformation and utilization.

After being processed into small glass particles, pretreated cullet can be used for a variety of purposes:

The use of glass shards as a combination of road surfaces has been tested in the United States and Canada for several years, and the use of glass shards as a road filler has the ability to reduce vehicle lateral slip accidents compared to other materials; The reflection of light is appropriate; The pavement is in good wear condition; The snow melts quickly, so it is suitable for use in places with low temperatures.

Crushed glass is mixed with building materials to make building products such as prefabricated building parts and building bricks. Practice has proved that the dimensional accuracy and strength of products formed under pressure with organic substances as cementing agents are high, and the production cost is low.

Crushed glass is used to make building surface decorations, reflector materials, arts and crafts and clothing accessories, and has a beautiful visual effect.

Mixtures of glass and plastic waste with building materials can be used to make synthetic building products, etc.

3. Refurnace reengineering.

After the glass is pretreated, it is melted back to the furnace to make glass containers, glass fibers, etc.

4. Raw material reuse.

The cullet of ** is used as an added raw material for glass products, because the right amount of cullet helps the glass to melt at a lower temperature.

5. Reuse glass bottles, and the reuse scope of packaging is mainly low-value and large-scale commodity packaging glass bottles. Such as beer bottles, soda bottles, soy sauce bottles, vinegar bottles and some canned bottles.

Disadvantages of glasses:

The texture is slightly heavier, easy to break, too high temperature will break, children are not safe to use, can not be smashed, transportation trouble, not resistant to dirt, no heat insulation, no heat preservation, can not be refrigerated, will mold.

How to improve the glass:

Sometimes it is not possible to meet the requirements of life in technology, and sometimes it is superfluous to complete the application in technology and hinder people's living habits. Technology and life are at odds. In any case, in the case of both technology and life, it is at least necessary to achieve beauty, ease of use, and prevent easy burns.

Wait a minute. <>

Classification of glasses:

Glass cups can be divided into single-layer glasses, double-layer glasses, and crystal glasses.

cups, glass office cups, glass mouth cups, etc. Double-walled glass, as the name suggests, is a glass that is divided into two layers when made, which can play a role in heat insulation and anti-scalding when in use.

The raw material of the double-walled glass is high borosilicate glass.

Food-grade catering glass, fired at a high temperature of more than 600 degrees, is usually made of high borosilicate glass tubes, large and small inner and outer tubes are baked by technicians under the sealing machine, is a new type of environmentally friendly teacup, more and more favored by people.

Notes:

For the first time using a glass, please wash it with a soft cloth and warm water.

If after a long period of use, when the inner tank produces heavy tea scale, you can pour a small amount of 84 disinfectant solution and soak it for a period of time and rinse it with water to make it as bright as new, and the outer surface can be cleaned directly with mild detergent and soft cloth. Each part must be cleaned after each use.

Please clean with a mild neutral detergent, in order to avoid scratches on the cup body affecting the appearance, do not wipe the cup with rough metal wool balls, etc.; When the glass is filled with boiling water, the water level should not be too full, so as not to overflow when making tea; Do not put the glass cup into the microwave, sterilizer and other high-temperature utensils to heat directly, so as not to cause deformation of the cup body and affect the use effect; Unscrew the lid clockwise (with your right hand facing you from left to right), otherwise it may cause burns; Children should use with caution to prevent the equipment from being broken or burned themselves.

Glassware is prone to burst when it is filled with excessively hot or cold water, so it should be used in an environment where the temperature difference is too large. Usually, the temperature difference of more than 80 degrees will cause the utensils to expand and contract strongly, which can easily lead to explosion. Unless otherwise specified, try to avoid using utensils with excessively hot or cold water.

Before pouring hot water, you can pour a small amount of water, and shake the utensils to make full contact with the hot water, so as to achieve the purpose of pre-preparing mountain heat for the utensils, and then pour hot water into the utensils, which can prevent the utensils from bursting due to excessive temperature differences.
