Durable Melamine Dinner Ware

Q: Is melamine dinner plate toxic?
A:
1.Melamine is a strong hardness, tight structure and durability of a thermosetting plastic, belongs to the polymer compound, it has corrosion resistance, high and low temperature resistance, bump resistance and non-toxic tasteless characteristics, the overall comprehensive performance is relatively good, because it is the plastic, it is easy to be dyed, after processing of the Miamine tableware, the color is very beautiful.
2.Miamine tableware is made from the use of the unit body of formaldehyde and melamine, these two units are non-toxic, tasteless and odorless, high hardness, high temperature and humidity stability and good crack resistance, the surface of this plastic is smooth and lustrous, the temperature of 54-80 degrees Celsius synthesis will not produce harmful substances to humans, so you can rest assured that you can use the Miamine tableware.

However, after a long time, the surface of the tableware will produce a certain amount of wear and tear, producing a certain amount of micro-cracking, so that the speed of the residual trace of small molecules migrate outward is increased. It is not recommended to place some hot food for a long time, because hot things will also accelerate the migration of residual small molecules precipitated inside.

Testing Of Lamines Tableware

But because of the high cost of the amine powder in life, some bad businessmen will use urea-formaldehyde compounds as the substrate for processing, and then coated with a layer of amine powder on the surface of tableware in order to pursue profits. Because urea-formaldehyde contains a lot of free formaldehyde, and people absorb too much formaldehyde will cause, people respiratory and other diseases, often use this tableware may also cause chronic poisoning, skin irritation, etc.. So now our country provides for the testing of the dense amine tableware, the common detection methods are:

1, using the cluster of independent soft mode method and the main components of the qualitative analysis of the discriminant analysis method, the establishment of 100% of the dense amine and urea-formaldehyde + positive surface dense amine tableware
The qualitative identification model was established by using the independent soft model method and the principal component discriminant analysis, and then the qualitative analysis of the principal components of the dense amine tableware.
2. The quantitative PL S model of the quality parameters of the dense amine tableware was established by near-infrared spectroscopy, and the correlation coefficients were drawn by various spectral pre-processing methods.

Then refer to the following data:
