Nowadays, the internet loves to talk about middle-aged people, especially middle-aged men, calling them greasy men, hey, just a lewd look. It probably means that men will become big-bellied, greasy skin and thinning hair when they reach middle age. The more exasperating is that some people also arranged a standard LOGO for middle-aged men – holding a thermos. As a middle-aged man, I have no objection to the word greasy man, but I think middle-aged men are more mature and full of wisdom. They over the age of struggle, more cherish the maintenance of their own, so insulation cup into their image pronoun is not surprising. Today I will talk specifically about insulation cup. Insulation cup is generally made of ceramic or stainless steel plus vacuum layer into the water container, sealed tightly, vacuum insulation layer can make installed in the internal water and other liquids to delay heat dissipation to achieve the purpose of insulation. Currently on the market, the majority of metal liner type insulation cup. This type of insulation cup liner are sandblasted electrolytic over, the purpose is to avoid direct contact between water and stainless steel material physical reaction. Thus, how to correctly use insulation cup is very delicate, improper use not only can not play a maintenance role, but will bring damage to the insulation cup liner. Use insulation cup to pay attention to the following matters: insulation cup is used to fill the water, do not use to fill juice or carbonated drinks and other acidic beverages. Once the inner liner is corroded, it is easy to precipitate heavy metal damage to the human body. Nutritious juice is not suitable for a long time high temperature preservation, or drink into the mouth just does not contain nutrients sugar water, and perhaps a large number of microorganisms, because sugar is a high-quality medium for bacteria. Hot milk easily do not load into the insulation cup, milk microorganisms in the higher temperature will also accelerate reproduction, so that the milk spoilage, deterioration, triggering organism gastrointestinal tract dysfunction. Decoction of good Chinese medicine deposited into the insulation cup should not be too long, Chinese medicine acidity and alkalinity, may corrode the insulation cup of stainless steel inner wall, chemical reaction, drink after injury. Middle-aged men like wolfberry is also the case. Any tea should not be immersed in hot water for a long time, especially in the insulation cup, high temperature will accelerate the destruction of nutrients within the tea, long bubble tea also lose the tea inherent aroma. Insulation cup cleaning is also a learned drop: cleaning can be used to point crushed eggshells and hot water injected into the insulation cup, shake the insulation cup up and down with force for about 1 minute, the cup is clean. You can also use salt water poured into the insulation cup to stand for 20 minutes, you can quickly remove the unpleasant rust smell. Of course with fresh orange peel or lemon slices placed in the insulation cup to stand for 4 hours will be able to remove all kinds of odors, but also incidentally left a light fragrance.
