一次性纸杯可以担心用来喝热水吗?
2018-1-25 16:49:47
一次性纸杯,是一种方便、卫生、价钱昂贵的纸质杯子,在许多场所都可以见到。但是在与人方便的同时,一次性纸杯的平安性却遭到人们的质疑。
Disposable paper cup is a kind of paper cup which is convenient, sanitary and cheap. It can be seen on many occasions. But at the same time, the safety of disposable paper cup has been questioned by people.
有人说,一次性纸杯要分冷饮杯、热饮杯。假如用冷饮杯装热水,水温超越 40 ℃时,杯内涂层的蜡就会消融。现在,国际的一次纸杯依据用处可以分为三种:冷饮杯、热饮杯及冰淇淋杯。而依据纸杯的涂层也可以分为三种:涂蜡杯、聚乙烯涂膜杯及直壁双层杯。
Some people say that the disposable paper cup should be divided into a cold drink cup and a hot drink cup. If the hot water is installed in a cold drink cup, the wax in the cup will melt when the water temperature is over 40. At present, a paper cup in China can be divided into three kinds according to its use: the cold drink cup, the hot drink cup and the ice cream cup. According to the paper cup, the coating can be divided into 3 kinds: wax coated cup, polyethylene film cup and straight wall double layer cup.

关于涂蜡杯,许多人表现不克不及了解,以为喝水时很没有“平安感”。实践上,涂蜡的目标是为了防水。由于蜡遇热会消融,以是涂蜡杯只能用作冷饮杯。而把涂蜡杯再加一层乳液就酿成直壁双层杯了,由于这种双层杯隔热性好,以是常用做热饮杯和冰激淋杯。冷饮热饮都能应付裕如的另有聚乙烯涂膜杯,原理是在杯壁掩盖有聚乙烯薄层,如许使得外表更润滑,杯子里面方便印刷精巧的图案,以是倍受快餐行业喜爱。

一次性杯子

For the wax coated cup, many people say that they can't understand it and feel that there is no "sense of safety" when drinking water. In fact, the purpose of wax coating is to be waterproof. Because the wax will melt in the heat, the wax cup can only be used as a cold drink cup. In addition, the wax coated cup is added with a layer of emulsion to turn into a double double cup, which is often used as a hot drink cup and ice cream cup because of its good heat insulation. Cold drinks and hot drinks can be easily handled and polyethylene coated cups. The principle is that there is polyethylene thin layer covered on the wall of the cup, which makes the surface smoother and the printed patterns on the outside of cups easier to print, so it is very popular with the fast food industry.
及格纸杯用的是食等级白腊,即使是不警惕喝进了肚子,也不用担忧,那点白腊不会对身材形成危害。再者,白腊的熔点很高,高的可以到达200多度。蜡消融后我们可以立刻用肉眼看到蜡酿成蜡油漂泊在水上,可以实时中止饮用。用冷饮杯艳服热水的真正风险在于,白腊消融后纸杯会得到防水性,很容易被热水穿透招致漏水,烫伤运用者。
The qualified paper cup is used for food grade paraffin, even if it is inadvertently drunk into the stomach, it is not necessary to worry that the paraffin wax will not cause harm to the body. Furthermore, the melting point of paraffin is very high, which can reach more than 200 degrees. After the wax melts, we can immediately use the naked eye to see the wax to float on the water and stop drinking in time. The real danger of filling hot water with a cold drink cup is that the paper cup will lose water resistance after the paraffin melts, and it is easily penetrated by hot water to lead to water leakage and burn the user.
