Typically, the compression time is 1 to 20 seconds, the curing time is 2 minutes to keep the air temperature in the mold. In the production process, it should be particularly noted that the mold will be scratched due to material corrosion and artificial reasons after using a period of time.
In response to this situation, the imitation porcelain cutlery manufacturer explained three methods of improving the quality of the imitation porcelain tableware. When the use is long and the amine powder is worn, the use hazard is not distinguished from the urea resin molding product. Semi-transmissive curing, weak acid, weak alkali, good insulation, good wear resistance, cheap, but encountered strong acid, strong base, poorly decomposed, and poor weather resistance.
Why don’t you say that there is no urea resin in 959 additives in GB9685-2009,Custom Eco-friendly Melamine Tableware Factory so far, the substances not listed in the standard cannot be used in food containers and packaging materials. Imitation porcelain tableware produced by melamine resin as the main raw material, due to production process defects, pollution resistance is easy to fail. It is illegal for plastic tableware for the production of urea-resin molding products.
Therefore, the pollution resistance is unqualified. In addition, the mold for producing imitation porcelain tableware is also a key factor. Using urea resin tableware is very harmful to the human body because the urea resin is a polymer obtained by the urea and formaldehyde.
At this point, grinding, polishing, and electroplating must be carried out, otherwise the traces on the product will deposit stains and difficult to remove. Urea is also known as carbonamin, and the decomposition is decomposed to produce ammonia gas when heated to 160 ° C while becoming cyanic acid.
