Heat is transferred by radiation, convection and conduction. The thermos has a vacuum insulator, silver plated flasks, a short bottleneck design structure that prevents and reduces the effect of heat transfer from the thermos.
The company, government and school and so on. All could contact Source EC to purchase customised thermos. Especially, when employees work in the office, using the thermos, looking at the company logo. This could strengthen their belonging to the company. Besides, it is also a good choice to send gifts to customers when the company has activity which could promote the company brand. Thermos is our daily necessity for drinking tea and restoring cold water in hot summer. How do the thermos work to maintain temperature? This article will introduce the principle of thermos to you.
The structure of the thermos
The stainless steel thermos has an inner wall, outer wall and stopper cap. There is vacuum insulation between the inner wall and outer wall. The inner wall is silver plated to maintain temperature.
The key to maintain heat
Heat is mainly transferred in three ways: by conduction, by convection, and by radiation.
Convection
Heat is transferred by convection in liquids and gases. So the gases between the inner wall and outer wall are vacuumed. The vacuum could stop the convection.
Production method
Bottle production
Vacuum pumping is one of the most important factors for the thermos insulation. There are two vacuum pumping methods: tail vacuum and tailless vacuum. Tail vacuum, also known as calandria vacuum, is a traditional vacuum method. It first vacuum the thermos, then seal the bottom of the thermos. Therefore, it leaves a suction tail at the bottom of the cup bladder. The suction tail is easily damaged by bumping because of carelessly falling, this could lead to the vacuum insulator leaking, which is bad for maintaining temperature competence. The tailless vacuum, also known as no-tail vacuum, successfully overcame this drawback. It uses a special method to weld the tail to get rid of the sharp exhaust tail. The tailless vacuum is very advanced. The tailless vacuum removes the tail to make the thermos space more effective. If the thermos has the same appearance, tailless vacuumed one have bigger volume, less weight and better heat maintaining competence. The advanced melt sealing technology seals the air hole tightly, which can avoid air leakage for a long time. Tailless vacuum thermos will have a long service life.
Cap production
The cap consists of rubber, plastic and silicone. The thermos inner space is surrounded by a vacuum insulator. The bottle rim is the only space to lose heat. The heat is easily lost in the bottleneck, so the bottleneck is designed as short as possible. For big volume thermos, the smaller the thermos rim is, the better it could maintain the heat.
Radiation
Heat transfer also could be transferred by radiation. The sun emits heat by radiation.The radiation is the heat flux by the form of electromagnetic waves. The heat flux happens when the thermos temperature and the circumstance temperature is different.
Production method
The best method to stop heat radiation is using heat reflection. The thermos inner wall is silver plated to stop heat radiation. Because silver is one of the best materials to stop heat radiation. This could slow down the speed of losing heat.
Knowing how to clean the thermos is a useful effective piece of knowledge to know. Here are some methods to clean the customised thermos and an introduction to the cleaning utensils. These are some tips about how to remove the odour, tea stains and water stains from the thermos.
Clean Tips to remove odour inside the thermos
Vinegar and bicarbonate of soda
Vinegar and bicarbonate of soda is the best choice to remove odour. Because of their individual characteristics, they are used differently. Vinegar is acidic. It could neutralise the alkaline odour. Bicarbonate of soda could neutralise the acidic odour. You can put the thermos in the sink, pour water to immerse the water. Then add vinegar and bicarbonate of soda. They will generate bubbles. After the bubbles all disappear, rinse the thermos. This tip is not suitable for the thermos that have silver coating on the inner bottle. Because the vinegar may corrode the inner silver coating. This may decrease the competence of anti-corrosion inside.
Rice Water
Pour the rice water into the thermos. Wait for some hours. The odour will be removed.
Tea leaf
Put tea bags in the thermos. Wait for almost half an hour. Then rinse the thermos twice or three times. Attention please! Close the thermos lid after the inside water is totally dried, or the water inside would cause odour.
Clean tips to remove tea stains and water stains
Lemon vinegar
Naturally fermented lemon vinegar doesn't have corrosion and is not bad for people and the environment. Method: Put 1 Litre hot water and 1 teaspoon lemon vinegar into the thermos. Wait for 1-2 hours. Then, use a brush to clean the inside. Clean principle: The tea stains and water stains have Calcium, Magnesium and Phosphate ions. The lemon vinegar can dissolve these minerals. So it’s easy to clean the thermos.
The lemon vinegar uses Acid-base neutralisation principle which are useful in five situations below: 1. Dissolve the stain to be easily cleaned. 2. Stop bacteria reproduction 3. Remove the odour 4. Neutralise the acidic and the alkaline to be easily cleaned 5. Stop the Metal rusting
Sodium percarbonate
Sodium percarbonate, the same as lemon vinegar, doesn't have corrosion and isn’t bad for people and the environment.
Method: Put 1 Litre hot water and 1 teaspoon Sodium percarbonate into the thermos. Wait for 1-2 hours. Then, use a brush to clean the inside. Clean principle: When Sodium percarbonate dissolves in the water, it will decompose to Hydrogen peroxide and Soda. The Hydrogen peroxide generates bubbles and the Soda has strong cleaning, These two chemicals could quickly remove the stain and sterilise.
Bicarbonate of soda
Bicarbonate of soda is also known as sodium bicarbonate or baking soda. It tastes slightly salty and alkaline. It's non-toxic. Not bad for the people and the environment. Based on the content of baking soda, it is divided into three series: medicine, food and industry. We have to choose a food series to clean the thermos, making sure not to eat mistakely.
Method: Put 200c.c marn water and 1 teaspoon baking soda. Close the lid and shake the thermos. Wait for 1-2 hours. Then brush the inside space. Principle: The majority of odour is due to the acidic chemicals. The baking soda is slightly alkaline. It could neutralise the acidic chemicals. And the particles of baking soda are so small that the particles could deeply clean those chemicals in the pores on the surface.
Clean utensils
When it comes to clean utensils, people may think of the melamine sponge. It’s very useful, but has its own drawbacks. Here are reasons that we don’t advise you to use melamine sponge to clean the thermos.
Melamine sponge is very popular in recent years. It doesn’t use any detergents. Just add some water, it can tidy up everything. The main ingredient in many abrasive cleaning sponges is melamine foam. Due to its great sound absorption, superior thermal insulation performance, and lightweight, it is also employed as the primary sound and thermal insulation material for bullet trains. Due to the main ingredient is Melamine foam, it may generate the toxic Melamine when faced with high temperature, oil and the acidic. Its chemicals may leave on the tableware, it may generate the toxic when we eat the hot food.
Are you wondering about how to pick a thermos bottle for gifts? Here to help you sort out a few points for choosing a theroms
1.Heat Preservation performance Insulation data will be indicated on the outer box or manual of the theroms bottle. It is recommended to choose a theroms of at least 6hr and >68 degree.
If the user will drink water during driving, it must be able to open the lid with one hand. A good one-click open lid is equipped with a saftey lock which you need to unlock it before pressing to open the lid. This can avoid accidentally pressing the open when the bottle is in the bag. It should be noted that even if they're all one-click opening lid, the buttons and opening design are still slightly different between different brands. The handiness will also vary, so remember to try the open button before buying it.
3.Cup lid removal design ( one-click opening)
When buying a one-click opening thermos, in order to avoid hidding stain after using the bottle for a period of time, make sure to buy a thermos with a removable mouth of bottle and also convenient and intuitive to use. Don't save money from a cheap but its lid is unable to remove one.
4.Cup mouth design(rotating open lid)
When buying a thermos with rotating lid, check the mouth of cup design where your mouth will contact with. Compared with the untreated sharp metal mouth of cup, It's better with a detachable plastic component added to the cup lid for your lips to have a comfortable experience while drinking.
5.Type of inner wall:
The inner wall of stainless steel thermos is mainly divided into three types of processes: matte(average level), glass polish(mid-high level) and Teflon coating(mid-high level).
The glass polish and Teflon inner wall is moer easily to clean than a matte inner wall. However, the price is relatively high.
6.Inner pot material: We offer a wide range of material for your inner pot choice. The common ones are stainless steel, ceramic, bone china, glass and Teflon anti-stick coating.
(1)Stainless steel
Composed of manganese,chromium,nickle and other other metal elements. 304 and 316 stainless steel are materials with better stability.
