How to choose the tank of the vacuum flask?
Use five recruit: water bottle at the bottom of the rubber gasket also shoulds not be screwed too tight, with water inside the fixed advisable. In order to have a heat bilges cold shrink space, prevent bile.
Using the fourth recruit: bottle temporarily need not when, first clean the inside, should never put a cork fortress, to separate, otherwise not only difficult to get more would burst bravery when used in the future
Using three recruit: every use of a few months later, should check whether there is scale inside wall adsorption, if yes, inside filled with warm water first, then pour vinegar right amount, soak overnight to soften it and fall off on their own. Because scale not only affects the heat preservation effect, but also because of scale with the glass heat bilges cold shrink coefficient, which is out of sync caused by blasting. Most of the inside blowout reasons in addition to human factors is the fault of the scale of
When used to learn the blowout Use a recruit: new bravery in warm water for 20 minutes before use, wash again after use, do not directly to the boiling water into, inside cold heat discomfort will burst; Using the second recruit: inside every time in the inland waters don't full of overflow, it is advisable to bottle stopper doesn't come in contact with water, so the cork with water between seems to form a "vacuum", has good heat preservation effect. And water bottle stopper if access to the boiling water, the water would not only have a wood, and the heat source will be along with the water through the cork out slowly, so as to shorten the time of heat preservation. Don't plug the bottle stopper is too tight, otherwise easy explosion, put in;
Select the five recruit The tank the most critical Vacuum flask is hard to find a good place to buy, but life have to use a lot of the time. So, exactly how to choose good quality vacuum flask? Listen to hum choose bottles Tip: many residents to buy bottle with a soil bottle set on the ear listen to hum, hum, the greater the heat preservation effect is better. TLC method for the identification of the personage inside course of study points out, this kind of listening is not particularly, an outer glass broken inside, the inner glass bravery also issued a "buzzing" sound, it is of the bile in the convection of air inside the sound. Mainly to see quality of the tank Pick the first recruit: buy a new bottle, it is better to let the sales staff to help you take out the tank watch, that about one cm at the bottom of the "little tail" are in good condition, because inside is two layers of glass, no air, "little tail" damage that has been in the air, can't heat preservation; Select the second recruit: can knock gently with your fingers inside the outer glass, if the sound is ringing, is no crack is good inside; Choose three recruit: check whether within the inside silver even, because silver plated to avoid the thermal radiation, prevent heat loss; Choose the fourth recruit: thermos insulation and bottle stopper has a close relation, select around smooth without the bottle stopper of concave and convex; Choosing recruit 5: check whether level off, the bottle cork is tight.
