Bark products, stems and roots of tree species with developed cork layer are thickened surface protective tissues. Ancient Egypt, Greece and Rome were used to make fishing nets, insoles, bottle stoppers and so on. Cork was recorded in China during the Spring and Autumn Period. The main tree species producing cork are Quercus variabilis and Quercus variabilis. Generally, plants with DBH greater than 20 cm for 20 years or more can be peeled for the first time, and the obtained skin is called scalp or primary skin. After that, it is peeled once every 10 ~ 20 years, and the skin obtained is called regenerated skin, and the skin thickness is more than 2 cm.

This structure makes cork bark have very good elasticity, sealing, heat insulation, sound insulation, electrical insulation and friction resistance, plus the advantages of non-toxic, tasteless, small specific gravity, soft hand feeling and not easy to catch fire, so far no artificial products can match it. Chemically speaking, the ester mixture formed by several hydroxy fatty acids and phenolic acids is a characteristic component of cork, which is collectively called cork resin.

These substances are resistant to decay and chemical attack, so they have no chemical effect on water, grease, gasoline, organic acids, salts and esters except concentrated nitric acid, concentrated sulfuric acid, chlorine and iodine. Widely used, such as bottle stopper, insulation layer of refrigeration equipment, lifebuoy, sound insulation board and so on.

Question 2: Why do thermos bottles use cork? It should be insulated. All right. The thermos bottle that my family just bought is that kind of plastic plug. After using it for a while, I felt that it was not as warm as a cork, so I replaced it with wood.

Question 3: Who knows what tree cork is made of? Authentic cork is the bark of Quercus variabilis, also known as Quercus variabilis, Quercus macrophylla and Cyclobalanopsis crassipes, which mostly grows in the Yangtze River valley in China and is usually mixed. The cork layer of Quercus variabilis is developed, which is the raw material for making bottle stoppers and other articles.

Question 4: What is the material of the kettle lid (cork)? It's bark, cork.

The best cork is in Portugal. Peel off the bark layer by layer. That's a stopper for good red wine.

Question 5: Is the thermos plug plastic or cork? Plastic is tight and warm.

Question 6: What kind of wood is the cork of the thermos bottle? What kind of wood is most commonly used? What wood is the cheapest? What kind of wood is the best? Chinese fir, pine and poplar are all very cheap in the south, as well as paulownia.

Question 7: How to get rid of the odor of wooden kettle plug? I suggest you wrap a little tea with a piece of gauze, and then wrap the wooden thermos flask. Tea must be below, not around. As the hot air evaporates, the thermos will taste like tea. Please thank me after seeing the effect ~ this is my invention patent, and I will give it to you for free for the first time today. Woohoo ~ ~ This is the patent of Magic Shadow, please indicate it when reproduced ~

Question 8: Why do thermos stoppers use wood? 1 slow heat conduction, heat preservation 2. Wood does not react with hot water, which is safe and hygienic 3. It is also a tradition 4. The cost is cheap. To sum up, so use wood.

Question 9: What is the cork in the thermos bottle made of? Made of cork

What is cork? Cork is the protective layer of China oak, namely bark, commonly known as Quercus variabilis. The thickness of cork is generally 4 to 5 cm, and the quality cork can reach 8 to 9 cm.

Cork grows in the Mediterranean climate and is abundant in the Mediterranean region. After planting for 40 years and harvesting once, the natural bark is harvested once every 10 year. It is a pure natural polymer material, and only Castanopsis eyrei and Quercus variabilis bark can be used to process cork products in the world.

Price cork is known as "soft gold", which has a series of excellent characteristics such as low density, compressibility, elasticity, air tightness, waterproof, moisture-proof, oil resistance, acid resistance, vibration reduction, sound insulation, heat insulation, flame retardant, insulation and wear resistance. Cork decorative materials combine many characteristics of cork and have incomparable advantages over other decorative materials. As early as 100 years ago, some developed countries in Europe began to manufacture and use cork decorative materials.
