Is the glass inner container of hot water kettle better or stainless steel? Many families are used to putting a hot water bottle at home for drinking, especially in winter, which can provide a long heat preservation time. First, let's see whether the glass inner container of the hot water kettle is good or stainless steel.

Whether the glass inner container of hot water kettle is good or stainless steel 1 depends on two aspects: thermal insulation performance and safety. As for heat preservation, I think stainless steel has better heat preservation performance, but personally, I think the glass liner is safer, healthier and has no peculiar smell.

When I was a child, the inner container of the thermos at home was all glass. If I accidentally knock it down, it will break the glass and will be criticized before long. I used to think it was not good at all, it was too easy to break down, but the insulation effect was really good. The water boiled at night can be stored until the next night without breaking the hot water.

The heat preservation effect of old-fashioned glass inner container thermos depends on the quality of vacuum double-layer glass inner container.

Boiling water, after boiling for five minutes, is put in a thermos bottle with a glass liner, and the mouth of the bottle is plugged with a cork, and the mouth is still hot after 24 hours. Modern science and technology stainless steel liner thermos bottle adopts food-grade 304 stainless steel as liner, and the shell is filled with heat insulation layer (or air heat insulation and heat conduction), which has the same heat insulation effect!

As far as household use is concerned, the glass inner thermos bottle should not be swaggered, but can be placed on the coffee table, and hot water can be poured at any time to make tea!

Stainless steel inner container thermos can be taken out or exercised at will, and can climb mountains and wading, run and keep fit, replenish water anytime and anywhere, clean and hygienic!

Stainless steel inner container thermos with smaller capacity, more expensive price and more convenient to carry; Glass vacuum liner thermos bottle, with larger capacity and lower price, is a family necessity for children and the elderly. Drinking warm water often is good for health!

Many people don't want to use the glass liner because they think it is fragile. But now, if the glass liner is made of good glass with high heat resistance and explosion-proof coefficient, there is no need to consider the problem of fragility and explosion. Glass liner is safer than stainless steel, and harmful substances will not be mixed in drinking water. It is recommended to use a glass liner thermos.

There is also a thermos bottle with a hollow resin liner, which is also very good, light in weight, warm and not easy to break.

Is the glass inner container of hot water kettle better than stainless steel? In terms of thermal conductivity, stainless steel has better thermal conductivity than glass. Good thermal conductivity means that heat is easily lost. From this point of view, the thermal insulation of glass material will be better.

From the health point of view, we still choose glass, which has less harmful substances. We can find that baby bottles are made of glass. Tea cups and juice cups made of glass should never be made of stainless steel. Tea cups should be made of advanced seasonal cups or ceramic cups, which can withstand the temperature change of boiling water.

So what are the advantages of stainless steel and glass thermos cups? The truly qualified stainless steel that will not have any adverse effects on human body should be food-grade 304 stainless steel, which has been clearly pointed out in relevant national standards. Because the iron contained in stainless steel is also a trace element that people need to ingest every day, stainless steel cups belong to alloy metal products, and the metal elements of these cups will be different according to different uses.

Common metal elements are iron, silicon, carbon, aluminum and so on. These elements cannot be provided by other cups. It can not only keep warm, but also keep out the cold, and it is also very convenient to use in daily life. Glass thermos, healthy but not fall-proof. The reason why the glass thermos cup is safer is that the glass is sintered by inorganic silicate, which is a very chaotic substance, that is to say, the bad impurities contained in it will not leak out in the production process. Moreover, glasses are easy to clean, and they are the safest.

But each has its own advantages, stainless steel is not fragile, and glass is easily broken. Moreover, the quality of thermos cups produced by different manufacturers is different. Some glass materials are not as heat-insulating as stainless steel. At present, the vacuum pumping technology of stainless steel thermos cups sold in the market can be divided into tail vacuum and tailless vacuum. The former is a traditional technology, and the latter is the most advanced technology at home and abroad. Tailless vacuum products have high vacuum degree, long heat preservation time, large effective capacity and long service life.

In addition, the appearance industry is very important, and the stainless steel thermos cup looks more elegant and upscale.

It depends on whether the glass inner container of the hot water kettle is good or the stainless steel inner container is good.

1, the glass conducts heat slowly, and the silver-plated glass liner can effectively reduce the external thermal radiation, so the glass liner thermos has better thermal insulation. But the glass is fragile, so you can choose a glass liner indoors and a stainless steel liner outdoors.

2. Compared with the thermal insulation effect, the glass double-layer vacuum liner has good thermal insulation, but as a portable use, the stainless steel thermos cup is convenient to carry and durable.

3. Another advantage of glass-lined thermos pots is generally overlooked, that is, glass thermos pots and stainless steel thermos pots with the same capacity are relatively light, and glass pots are generally only one-third of the weight of stainless steel pots.

4. The advantages of stainless steel liner are good material, high strength, high temperature resistance and corrosion resistance; Stable performance and not easy to rust. At the same time, it has strong compression resistance and good thermal insulation performance, and the glass liner is not easy to break.

Is the glass inner container of the kettle better or stainless steel? 4. What is the inner container of the thermos?

1, stainless steel liner

Most of the thermos pots with stainless steel insulation liner are made of food-grade 304 stainless steel, which has strong corrosion resistance and low thermal conductivity, and can provide good insulation effect after interlayer vacuum treatment.

2, glass liner

High borosilicate glass or borosilicate glass is mostly used in insulated kettles with glass liners, with good high temperature resistance and safe use. Silver plating on glass liner can also use the principle of specular reflection to reduce heat loss and improve heat insulation effect.

3, ceramic liner

Ceramic insulation liner is safe and harmless, but the cost and insulation effect are not particularly ideal, so there are few insulation pots with ceramic liners in the market.

4, purple sand liner

The inner container made of purple sand has certain functions of heat preservation, health preservation and conditioning, and is usually used with stainless steel shell to improve the heat preservation effect and service life. Another advantage of purple sand thermos is that it is slow in heat transfer and not easy to heat.

5, plastic liner

The plastic liner only has heat preservation function, which has short heat preservation time and poor heat preservation effect, and is generally not used often, so there are fewer plastic heat preservation pots on the market.

2. Is the glass thermos better or the stainless steel thermos better?

1, insulation effect

According to the requirements of national standards, the daily thermal insulation container for double-layer glass vacuum bottle liner is 1.8~2.0L, with a diameter of 40~44mm, temperature measuring time of 24h, and the thermal insulation efficiency is ≥60 degrees Celsius; The capacity of stainless steel products with inner plugs is ≥ 1.8L, and the caliber is ≥ 39 ~

2. Materials

Glass thermos adopts high borosilicate glass or borosilicate glass, and stainless steel thermos adopts food-grade 304 stainless steel or 3 16 stainless steel.

Step 3 use

Stainless steel liners are generally not used to hold acid-base liquids, or fruit juice, milk, carbonated drinks, etc. So as not to cause chemical reaction, but it is no problem to hold hot water every day. The chemical properties of glass are more stable and there will be no acid-base reaction, so the glass liner is relatively safer.

Step 4 use

The use experience of glass thermos and stainless steel thermos is similar, but due to the different materials, glass thermos is easier to break than stainless steel thermos. If you have children at home, you must put thermos flask in a safe place where they can't reach.

Generally speaking, stainless steel thermos and glass thermos have their own advantages and disadvantages. How to choose depends on the needs of the family, but no matter what kind of kettle you choose, you must choose the products produced by regular manufacturers to buy.
