Imitation porcelain tableware is non-toxic, correct use is not harmful
In response to recent market rumors that “the imitation porcelain meal is poisonous and the raw material is 90% melamine”, the China Plastics Processing Industry Association held a press conference yesterday in Beijing, saying that melamine tableware is a safe and reliable daily necessities as long as it is properly applied.
Since November last year, the society has begun to have porcelain-like meals with toxic and other speech spreads. Some supermarkets have placed melamine tableware under the shelves. Consumers have doubts about melamine tableware, and the Chinese melamine tableware industry has suffered serious losses.
According to the association's rough statistics, since November last year, the output of various melamine tableware manufacturers in the country has been reduced by at least 50%.
"Since the end of last year, the company's production and sales have plummeted. So far, the sales volume has decreased by about 10 million yuan compared with the same period of last year." Wang Wei, general manager of Zhejiang Taizhou Hill Company, said.
Liao Zheng, president of the China Plastics Industry Processing Association, said here yesterday that any industry that has not produced inferior products according to standards can not completely erase the entire industry.
Chen Ruifu, a chemical raw material expert, said that the material used in melamine tableware is melamine resin, which is a kind of melamine and formaldehyde - note that these two are "toxic" substances - formed under the chemical reaction under certain conditions. High molecular polymer.
However, this reaction is irreversible. In other words, the two substances have become another substance through chemical bond exchange and other forms. More importantly, the substance is non-toxic and will not A toxic substance such as melamine is precipitated.
With the development of the process, new melamine tableware coated with urea-formaldehyde resin-encrypted amine powder has appeared on the market. Chen Ruifu introduced that due to the same chemical bond, the melamine coating can be firmly combined with urea-formaldehyde resin. Therefore, the new type of melamine Tableware also has all the physical characteristics of melamine tableware.
It is understood that melamine tableware has been used at home and abroad for more than 40 years. At present, China is the world's largest manufacturer of melamine tableware, accounting for about 80% of the world's production.
