Does melamine meal have hidden dangers of quality and safety?​

Does melamine meal have hidden dangers of quality and safety?

1. Qualified melamine tableware.

Qualified melamine tableware is safe for normal use.

Due to the above-mentioned physical and chemical characteristics of melamine tableware and its price advantage, melamine tableware has a wide range of applications in tableware, daily necessities, etc.Common applications are mainly in infant tableware (fear of breaking), and some restaurant chains ( Price, easy to order, decals and gold coloring form the inherent characteristics of the enterprise), such as Zhangzhou's Yonghe Soymilk, Western fast food, congee trays, etc. all use melamine tableware.

After using for a period of time, melamine tableware is affected by various solvents, such as acid, alkali, fat, alcohol, physical wear, and long-term heating. The surface of the tableware (that is, the glazed surface is actually the same as the principle of glazed porcelain) It is easy to form a layer of brown speckled marks, which affects the appearance of tableware. If you are careful, this is actually the case with our porcelain tableware for a period of time, and it is still safe under normal use. However, after all, it is not beautiful and can be replaced.

The so-called normal use of melamine tableware refers to: normal diet, heat-resistant to 120 ° C, can not be fired, and contains some highly corrosive items (corrosives such as tree alkaloids commonly used in life).

2. Inferior melamine tableware.

The so-called inferior refers to the unqualified products produced by using melamine powder; the so-called fake refers to the use of urethane resin tableware as melamine tableware. Due to the simple production process of melamine tableware and the small scale of the enterprise, molds, equipment, workers and other aspects have also led to many unqualified melamine tableware flowing into the market (so-called inferiority). However, there are more "false" than "bad" products in the market, that is, melamine tableware is pretended to be melamine tableware.
Melamine Tableware Mold
In fact, melamine tableware made of urethane resin tableware is mainly caused by price factors. The production processes and processes of the two are basically the same as above, and the difference lies in raw materials. Melamine powder, the main raw material of melamine tableware, is a melamine melamine formaldehyde tree finger formed by the reaction of melamine and formaldehyde; and A1 powder, which is the main raw material of urethane resin tableware, is a urethane resin formed by the reaction of urea and formaldehyde. The core difference between the two is whether to use melamine or urea to synthesize with formaldehyde. The price of melamine is higher than that of urea, and the molecular weight is also larger than that of urea. The synthesized A5 powder is more stable than A1 powder. This is a bit like the glue used for home decoration or construction. The difference is whether or not melamine is incorporated in it.

From the above, we can see that due to the different choices of raw materials, the molecular structure of the products is different, and the performance of genuine and fake melamine tableware is also different: 

①The strength is different, "true" is stronger than "false". Strong; 

② Different adsorptivity, "True" is easier to clean than "False";

③ Different heat resistance, "True" can withstand 120 ℃, "False" can only withstand to about 80 ℃; 

④ Different color fastness, "True" "Than" is more difficult to discolor and decolorize the legs; 

⑤ Different sanitary properties, "True" can meet the standards of edible tableware, "False" is not edible tableware and cannot be used as a container directly in contact with food.


 The harm of fake and inferior melamine tableware lies in its instability, the free formaldehyde exceeds the standard, and it may cause cancer in the long run and cause chronic harm to health.
