What is Melamine Powder?
Melamine is an organic chemical raw material with a wide range of uses. The main purpose is as a raw material for the production of melamine-formaldehyde resin, as well as flame retardants, water reducers, and formaldehyde cleaners.
Since most regions mainly estimate the protein content of food by measuring the nitrogen content, the nitrogen content of melamine is about 66%, which is much higher than the average protein nitrogen content of 16%. Therefore, in order to increase the nitrogen content , Some unscrupulous and lawless vendors mixed melamine into food, which made the protein test content of the food falsely high, thus making the inferior food misunderstood.
Melamine Powder Uses
- Melamine powder compounds that form synthetic resins with formaldehyde.
- Melamine powder use formaldehyde to form synthetic resin.
- Melamine powder used in the manufacture of high-pressure laminate resins (for example, decorative countertops), molding compounds (for example, tableware), and surface coating resins (for example, home appliance finishes and automotive finishes). Other main products are textile and paper processing resins. Other uses include adhesive resins for bonding wood, plywood and floors, and resins for leather tanning agents. Melamine, melamine cyanurate, other melamine salts and guanidine compounds are currently the most used nitrogen-containing flame retardants. Melamine is used as a flame retardant additive for polypropylene and polyethylene. Melamine cyanurate is used commercially as a flame retardant for polyamide and terephthalate.
Detection Method of Melamine Powder
S1. Prepare melamine standard solutions of different concentrations as 0mg/kg, 15mg/kg, 25mg/kg, 45mg/kg, 100mg/kg;
S2. Add the standard solution of melamine in S1 into the milk powder dissolving solution respectively, and mix them thoroughly to obtain several mixed solutions;
S3. Mix the mixture in step S2 with 99.8% absolute ethanol at a ratio of 1:1.5, and centrifuge to obtain the supernatant liquid;
S4. Drop the clarified liquid in step S3 on the metal evaporating dish respectively, and dry the metal evaporating dish;
S5. The melamine in the melamine standard solution is detected by confocal microscopy Raman spectroscopy and the Raman spectra are obtained, and they are numbered D1, D2, D3, D4, and D5;
S6. Perform confocal Raman spectroscopy detection of the residual melamine on the evaporating dish in S4 to obtain a Raman spectrum, and number the evaporating dishes as T1, T2, T3, T4, and T5;
S7. Compare the Raman peaks of D1, D2, D3, D4, D5 with T1, T2, T3, T4, and T5 respectively to determine whether the milk powder contains melamine.
