Disposable cup material testing

With the continuous improvement of living standards, people's demands are also changing. At that time, it was about quantity, but now it is about quality. So, while people's demand for hygiene has increased, it has also given rise to some newly emerging eating utensils. So a large number of disposable products have emerged in the market. Indeed, these disposable products are very convenient and recognized by people, so they are highly favored and can be seen in many places. However, people often overlook their impact on themselves. So, are disposable products beneficial or harmful to the human body? In April 2004, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China conducted supervision and spot checks on the quality of paper cups, involving 61 products produced by 42 enterprises in 7 provinces and municipalities, including Beijing, Zhejiang, Shanghai, and Jiangsu. The pass rate of the spot checks was 86.9%, There are 8 types of paper cups that are unqualified: Hangzhou Jieli Paper Products Co., Ltd. Yiwu Oasis Paper Cup Tableware Co., Ltd. Beijing Jinri Jitong Science and Trade Co., Ltd. Disposable Cup Beijing Fuhao Paper Products Co., Ltd. Beijing Longwei Jiaye Economic and Trade Development Co., Ltd. Hetong Paper Cup Factory in Chaheji Township, Bazhou City Beijing Jinrunlai Industry and Trade Co., Ltd. It was near the Hongli Paper Cup Processing Workshop in Jianghan District, Wuhan City in January 2007, The incident of medical waste turning into disposable cups. A reporter from a certain newspaper came to a paper cup manufacturer in Xigu based on the address provided by a freight worker in the market. This factory not only produces plastic cups but also disposable paper cups. In front of a machine, workers were pouring various discarded plastics soaked in a large pool into the high-temperature dissolving machine. The reporter found that some plastic fragments with needle scales were mixed in these fragments. Then, the dissolved plastic strips are put into the production machine, and some auxiliary materials are added. The discarded plastic becomes plastic pieces one by one, which are put into the cup making machine. It takes not much time, and one plastic cup is made from another machine mouth. In another pool, a large amount of various waste paper products are soaked. It is understood that these materials are used to make disposable cups. During the production and processing process, a large amount of fluorescent whitening agent is added, which makes the paper cups very white and clean. Therefore, the selection of disposable cups is very important for distinguishing between good and bad. So, how to identify it? In summary, it can be summarized as "three looks" Look at the packaging. The product packaging should indicate the name, address, product execution standards, production date, etc. of the production enterprise Look at the appearance. The shape of the paper cup should be straight and should not be deformed. When selecting a paper cup, you can gently press the sides of the cup with your hand to roughly determine the stiffness of the cup body. If the color of the paper cup is too white and looks abnormal, do not buy it Look at the manufacturer. Generally, purchasing products from legitimate manufacturers through legitimate channels can ensure hygiene conditions. In addition, when the content of harmful ingredients in disposable cups is high, preliminary identification can also be made. You can add hot water to the paper cup. If it will deform severely and even emit a strange smell when held up, it must not be used. If you have a fluorescent lamp (a type of lamp that can verify the authenticity of RMB) on your body, place a disposable cup under its light and illuminate it. If the cup body appears blue, it contains a large amount of fluorescent whitening agent
