Are melamine plate heat-resistant?
Are melamine plate heat-resistant? Can melamine tableware be sterilized by boiling in hot water? Qualified melamine tableware is fine. One of the standards of melamine tableware requires the “moisture resistance and heat resistance” test for melamine tableware, that is, put the melamine tableware in boiling water for 30 minutes, then take it out, place it at room temperature for 1 hour, repeat 3 times, and The untested samples are compared and observed.
However, there are many poor-quality melamine tableware on the market instead of melamine-formaldehyde resin. Urea-formaldehyde resin is prepared from a solution of urea and formaldehyde in alkaline or formaldehyde solution, and releases formaldehyde gas after hydrolysis. The more water, the stronger the acidity, the higher the temperature, the more severe the hydrolysis, and the more formaldehyde gas released. Therefore, the use of unqualified tableware is harmful to the human body.
3. The normal use temperature of melamine tableware is about -30℃-120. In the process of use and sterilization, pay attention to heating evenly, and the steam sterilization time should not exceed 5 minutes. It is strictly prohibited to use fire to bake directly, do not use microwave ovens and ovens; 84 disinfectants and other highly corrosive detergents should be used with caution. High concentrations will corrode the surface of the tableware and affect its service life.
Although melamine tableware does not contain toxic substances, melamine tableware is synthesized from formaldehyde and melamine. If they are not properly polymerized, melamine will remain in the tableware. Therefore, consumers should choose well-known brand tableware when buying melamine tableware, and never buy inferior products.
