Correct usage and precautions of glass

In daily life, it is very common for units, enterprises and individuals to customize various styles of glasses. Many consumers also like to use glasses to drink water, because glasses are constantly high in appearance, easy to clean, healthy and environmental protection. They are the first choice for many people to drink water. But sometimes when the glass is filled with hot water, it will burst suddenly, causing harm to us and taking many people off guard.

So what should we pay attention to when using glasses in our daily life?

How to use the glass:

1. Cleaning and maintenance: please rinse the inside and outside of the cup with clean water when using it for the first time; After each use, be sure to clean it in time, so as to keep the cup crystal clear and transparent. If not used for a long time, please ensure that the cup body and cover are dry and stored in a cool and dry place.

2. After adding water, please stand the cup upright for 3 seconds and then cover it. Standing upright can make the gas in the cup run out of the mouth of the cup in the fastest way. Don't cover it immediately, so that the gas can run out in time.

3. It is recommended to add water less than 20mm away from the cup mouth to avoid overflow and scald after twisting the cover too full; When filled with water, the cup cover shall not lock the teeth excessively, so as not to damage the bottom of the inner tank.

4. Do not cover the glass cup with foaming drink or cleaned with foaming detergent, so as to avoid the air bubbles generated in the cup, damaging the inner tank and even explosion. If it is filled with "health water", we should pay attention not to fill it too full, leave a breathable space and drink it in time (the cover is opened frequently, which is conducive to the release of gas in the cup). When not drinking, it is recommended to pour out the soaked drugs and food materials on the same day and clean them with clean water. If not cleaned in time, it is easy to leave dirt on the glass wall, which will not only affect the beauty of the glass, but also breed some bacteria and affect people's health.

5. It is not allowed to contain foaming and fermentation substances in a sealed state to prevent inflation or other adverse reactions, resulting in accidents. If juice, red jujube, fat sea and other foods are easy to lead to fungal growth and reproduction. If jujube is stored in water for too long, it will ferment and produce a large amount of gas. Due to the good tightness of the glass, the gas will continue to expand in the glass, increasing the pressure in the glass. The glass itself is not a high-pressure container. When the internal pressure is too high, the glass will expand and explode.

Precautions for glass use:

1. When cleaning the cup body, please use neutral detergent and scrub with a soft cloth; Do not scrub the cup body with metal brush, grinding powder, decontamination powder, etc;

2. Do not put it in the refrigerator for freezing or microwave heating, and do not use the dishwasher to clean, disinfect and disinfect the cupboard; The cup or body may be damaged by explosion;

3. Do not use fire or as cooking utensils;

4. Do not scratch with hard objects to prevent damage to the cup body;

5. Do not contain all kinds of toxic or harmful substances; Do not store carbonated drinks or substances with high pH;

6. Place it out of the reach of young children;

7. Please do not soak the cup cover for a long time. If the temperature is too high, the cup cover will be damaged.
