陶瓷杯:运用陶瓷杯最佳选用本性杯,要是抵挡不住颜色的引诱,就伸手摸摸颜色外表,假如外表光滑,就阐明是釉下彩或釉中彩,相对对比安全;假如凹凸不平,用指甲抠还会呈现脱落景象,则阐明是釉上彩,最佳不要采购。

磁化杯:只要负极的磁化水才能改进人体生理功能,起到保健的效果,而正极的磁化水不宜多喝。咱们在市场上所见到的磁化杯大多采用一般磁铁,正负极不分。因此,消费者在挑选磁化杯的时分应该细心辨别,选购单极磁片(负极)为质料制成的磁化杯。

纸杯:市场上的纸杯分为三种:第一种是用白卡纸做的,不能盛水和油。第二种是涂蜡纸杯,只要盛的水温度超越40℃,蜡就会融化,开释致癌物质多环芳烃。第三种是纸塑杯,假如选用的资料欠好或是加工技术不过关,在聚乙烯热熔或涂抹到纸杯的过程中就会发作裂解变化,发作致癌物。

不锈钢杯:不锈钢杯的优点是坚固耐用、防锈防腐蚀。但不锈钢杯属于合金制品,富含较多的重金属物质,因此在平时运用中,要留意不要用不锈钢杯装酸性饮品,假如汁、咖啡、碳酸饮料等;也不行长期盛放酱油、醋、菜汤、茶水等,由于这些食物中的电解质也许会与不锈钢中的重金属物质发作化学反应,致使重金属物质被分出。

搪瓷杯:由于搪瓷杯是通过上千摄氏度的高温搪化后制成的,不含铅等有害物质,能够放心运用,但有破损的搪瓷杯盛放饮品时简单分出有害物质,应决断淘汰

Glass: because the glass is not rich in chemical machine, with a glass of water and use up more clean and safe, choose must choose transparent glass and common glass, only need to pay attention to is that the glass is the most afraid of heat bilges cold shrink, don't immediately fill into the hot water temperature too low glass, to prevent the crack. But if the colorful glass in glass coated with paint, through open blisters may dissolve cancer-causing chemicals, and many manufacturers with the waste pipe of crystal glass containing lead, use undeserved, may cause lead poisoning.

Ceramic cup: using ceramic cup best choose nature cup, if you can't resist the allure of the color, will stretch out his hand to touch color appearance, if the surface smooth, just to clarify is under the glaze color or glair, relative comparison security; If uneven, with nails dig will appear fall off, is clarified on the glaze color, best not to purchase.

Temperature: the vacuum flask from the material on the market is divided into glass vacuum insulated container and stainless steel vacuum heat preservation container two kinds, the former see more of a thermos, tank vacuum insulated lunchbox, glass, etc., which is a stainless steel vacuum cup.

Plastic cups, plastic often add plasticizer, which contain some poisonous chemicals, plastic cup of hot water or hot water, the poisonous chemicals is simple dilution to the water, and plastic internal microstructure has a lot of aperture, which hides dirt. So, the expert suggests that plastic cup when the choose and buy, must be selected in accordance with national standards made of food grade plastic cups.

Magnetization cup: as long as the cathode of the magnetized water can improve human body physiological functions, have the health care effect, and the anode of the magnetized water not to drink more. We have seen in the market most of the magnetizing cup with magnets, plus or minus pole points. In picking time of the magnetizing cup as a result, consumers should be careful to distinguish, the choose and buy the single disk (cathode) for material made of magnetizing cup.

Paper cups, paper cups on the market is divided into three types: the first kind is made of white cardboard, not water and oil. The second is waxed paper cup, as long as the water temperature above 40 ℃, wax will melt, allaying carcinogenic polycyclic aromatic hydrocarbons. The third is, paper cup, if choose owe good or information processing technology does not pass, in the polyethylene melt or paper cups in the process of application and the cracking will attack changes, attack carcinogens.

The advantage of stainless steel cups, stainless steel cup is strong and durable, rust corrosion. But the stainless steel cup belong to alloy products, is rich in more heavy metal material, so in use at ordinary times, be careful not to use the stainless steel cup acid drinks, if the juice, coffee, carbonated drinks, etc.; Not long cheng fang soy sauce, vinegar, soup, tea, etc., as the electrolyte in these foods may attack and stainless steel in the heavy metal material in chemical reaction, cause heavy metal material was separated.

Enamel cup: as the enamel cup is made by thousands of degrees Celsius, after the high temperature in China, contains no lead and other harmful substances, can feel free to use, but there is any breakage enamel cup serving drinks when simple gives off harmful substances, decisions should be eliminated
