Insulation cup is one of us usually indispensable daily necessities, insulation cup has brought us a lot of convenience, it is because the practical insulation Cup, thermos cup into the thousands of households, due to continuous innovation in insulation Cup, thermos cup now can not only insulation but also the cold, the it has brought us more convenience, the summer to play the role of cold, but everyone in the pursuit of insulation Cup, at the same time, there is no thought at the time of purchase to test the insulation cup is qualified? If buy substandard it not suffer a great deal! Today we are going to listen to the tiger cup experts to tell you how to move! The first: Insulation Detection Because the vacuum insulation cup is used in vacuum insulation technology, because the vacuum case can prevent heat transfer to the outside, so as to achieve the effect of heat preservation. So the insulation effect detection vacuum thermos cup just 100 degrees of boiling water into the cup, after two or three minutes, the hand next vacuum insulation cup parts, look hot, if the position of the heating, the temperature will be lost from the place. Like the cup where the general will have a slight fever is normal. Second: sealing detection First, twisted a cup cover, a cup cover and the cup is it right? Look at the body perfectly, then in the cup, add boiling water (preferably boiling water), and then the cup upside down for two to three minutes, to see whether there is water leaking. Third: identification of plastic parts Vacuum insulation cup used plastic should be food grade, this plastic smell small, bright surface, no burr, long service life, not easy ageing. The characteristics of the common plastic or plastic recycling is the smell, color gray, burr, easy aging of easy fracture of plastic, after a long time but also smelly. This will not only make the vacuum insulation Cup shortened life expectancy, but also on our physical health threat. Fourth: capacity detection Because the vacuum insulation cup is double, so the actual capacity of the cup and we saw will have certain discrepancy. Look at the depth and the vacuum insulation cup liner with height difference (18-22mm), many small factories in order to reduce costs, often to this may affect the vacuum insulation cup capacity in materials. Fifth: identification of stainless steel Stainless steel material variety, where 18/8 denotes the stainless steel material containing 18% chromium, 8% nickel, reached the standard materials, in line with the national food standards is the green environmental protection product, antirust, corrosion products. Ordinary stainless steel material color is pale or dark, if the brine into the concentration of 1% will produce rust after 24 hours, which contains some elements exceed the standard, the direct harm to human health.
