Melamine tableware technical indicators

1. evaporation residue: ≤10mg/ L;
 

2. potassium permanganate consumption: ≤10mg/ L;
 

3. formaldehyde: ≤30mg/ L;
 

4. 65% ethanol decolorization test: negative;
 

5. the product heat resistance, impact resistance, bending and other performance and health indicators can meet the requirements of GB9690-88.
 

Due to the difference between the actual curing degree and the theoretical curing degree of melamine plastic products and the influence of acid, alkali, fat, alcohol, and long-term heat, melamine plastic products in use for a certain time, the product surface is easy to form a layer of brown freckled traces by friction.

Therefore, the technical performance of the developed solvent-resistant dense amine plastic product can reach:
 

1. potassium permanganate consumption (Mg/L) : ≤3;
 

2. the product heat resistance, impact resistance, bending resistance and other performance and health indicators can meet the requirements of GB9690-88, QB1999-84;
 

3. can extract formaldehyde ≤1.0mg/ L.
