The thermal insulation cup is a must -have for the winter of many people, but do you know?There is also a hidden health hazard behind the warmth of the insulation cup. If it is not cleaned or used in time, the insulation cup may become a hotbed of various bacteria.Lets take a look at the cleaning cup cleaning method and the choice method of the thermal heating cup.
How to buy the insulation cup
The quality of the preservation cup on the market is mixed. How should ordinary consumers be identified? It should focus on the insulation performance of its internal orchid structure, the degree of sealing of the cup lid and the bottle body, and whether the material releases harmful substances.
1. Internal warming identification
This is the main technical indicator of the thermal insulation cup. After filled with boiling water, tighten the bottle or cup lid clockwise. After 2 to 3 minutes, touch the appearance and lower part of the cup body with your hands.The phenomenon of warmth indicates that the endin can lose the vacuum and cannot achieve a good thermal insulation effect.
2. Differential sealing performance
Fill a glass of water for four or five minutes, tighten the lid, flatten the cup on the table, or throw it a few times. If there is no leakage, it means that the sealing performance is good;Whether the rotation is flexible and there is a gap.
3. Environmental identification of accessories
The environmental protection of plastic accessories is also worthy of attention. It can be identified by smelling taste. If the cup is made of food -grade plastic, the smell is small, the surface is bright, the long -notch is not easy to age; ordinary plastic or recycling plastic will be recycled.The smell is large, the color is dark, the burrs are large, and the plastic is easily aging and easy to break.
4. Identification of stainless steel materials
There are many specifications of stainless steel materials. Among them, 18/8 indicates that the composition of this stainless steel material contains 18%chromium and contains 8%nickel. The material that meets this standard is green and environmentally friendly products.If it is made of cups made of ordinary stainless steel cups, the color is white and dark. If it is soaked in 1%saline with a concentration of 1%, it will produce rust spots.healthy.
What are the types of thermal insulation cup
1. Stainless steel insulation cup
Stainless steel should be a food grade 304 stainless steel, and the relevant national standards have clearly pointed out this.Because the iron contained in stainless steel is also a trace element we need to take every day.It can not only keep warm, but also keep cold, and it is also convenient to use in daily life.
But the stainless steel insulation cup should not be used to make tea and coffee.Because tea leaves are soaked in the warm water in the thermal insulation cup for a long time, like mild fried eggs, the tea polyphenols and tannins contained in tea will be soaked in large quantities.In addition, because the water in the thermal insulation cup will always maintain a high water temperature, the aroma in the tea will quickly volatilize, and it will also reduce the clear aroma of the tea.The worst point is that the vitamin C and other nutrients contained in the tea will be destroyed when the water temperature exceeds 80 ° C, losing the health function of tea.
In addition, because stainless steel is a metal synthesis, the material contained in it is a relatively active substance, and some impurities will inevitably occur during the production process. These impurities will be harmful to the human body.In addition, some inferior stainless steel insulation cups will inevitably appear in the market. Such a thermal insulation cup cannot guarantee whether it is equally safe.
2. Glass insulation cup
Glass insulation cup, healthy but not falling.The reason why the glass thermal insulation cup is safer, because the glass is made of sintering from inorganic silicate, and it is a very stable substance, that is, the adverse impurities contained in the production process will not be leaked.And the glass is easy to clean, so it is the safer to use the glass.However, glass tea has the disadvantages of crushing, so it is not convenient to use it with you.
3. Purple sand insulation cup
The purple sand insulation cup not only has the basic function of the stainless steel thermal insulation cup, but also can make tea, which has health and conditioning effects.The purple sand insulation cups produced by regular manufacturers are generally developed by authentic pure natural purple sand mud (small) precision. The shell is usually a stainless steel material that is anti -falling and anti -banging.In addition, the hot and coldness of the purple sand insulation cup is highly adaptable. Regardless of the cold winter or hot summer, after the boiling water is injected, it will not cause swelling due to the rapid changes in temperature, and the sandy insulation cup will be slow and not hot.
4. Ceramic insulation cup
The ceramic thermal insulation cup is not in the insulation cup industry. The ceramic cup is completely harmless. It will not be used as metal cups and plastic cups. Long -term use will have the possibility of ingesting metal.
Insulation cup cleaning method
The thermos cup should be cleaned once a day, and the cup noodles, inner linery, and bottle caps should be cleaned to prevent dirt from creating. If it has produced odor and stains, dont worry. Xiaobian tells the cleaning method!
Step 1: Wash the inner bile to go to the odor
Pour salt in the thermal insulation cup, heat the water, shake it fully, soak for 5 to 10 minutes, and then rinse it.Essence
Step 2: Cleaning the gap of the cap
Remove the cup lid, squeeze some toothpaste on the toothbrush, gently wash the gap in the bottle cap, and then rinse it with water.
Step 3: Rinse the overall water
Rinse the overall water inside and outside the cup.
Step 4: Wipe dry and dry
After washing, dry it thoroughly and cover it to avoid stinking the stainless steel insulation cup.
