Hello everyone, today I will answer some questions about the dangers of melamine, including the safety scope of melamine. Many people still don’t know it. Therefore, today I will answer some questions about the dangers of melamine. Let’s analyze and analyze, now let’s take a look! If your problem is solved, I hope you will pay attention to this site, thank you~

1. How does melamine board evaporate toxic substances
Melamine board is an artificial board, and glue will inevitably be used during the production process. Therefore, melamine board will release harmful substances such as formaldehyde; if formaldehyde exceeds the standard, it will have a certain impact on the human body. Melamine is a high-strength resin with low toxicity. It will not harm human health as long as it is not taken orally. It generally does not evaporate toxic substances after curing. Therefore, melamine veneer will not add toxic and harmful substances to the board.
2. Melamine safety range
To protect the human body to a greater extent In terms of health, Chinese experts have determined the daily human tolerance of melamine to be 0.32 mg/kg of body weight, which is nearly half lower than the international standard of 0.63 mg/kg of body weight.
To evaluate the health hazards of melamine, we must consider the population\’s daily tolerable intake, which is an internationally accepted population safety standard for food contaminants. The intake limit refers to \”the intake of pollutants below this level per kilogram of body weight per person per day will generally not have an impact on health.\”
At present, the common international practice is to use the safe dose obtained from animal experiments divided by the safety factor (usually 100) to determine the daily dose of the human population.daily tolerated intake. The safe dose of melamine for animals is 63 mg/kg body weight, and the daily tolerable intake for humans should be 0.63 mg/kg body weight. In order to protect human health to a greater extent, Chinese experts have reduced the daily tolerable intake of the population to 0.32 mg/kg of body weight.
The person in charge of the relevant department gave an example, assuming that the weight of adults, children and infants is 60 kg, 20 kg and 7 kg respectively. The daily intake of melamine per person should not exceed 19.2 mg, 6.4 mg and 2.24 mg respectively, which will not cause harm to health.
3. What are the quality hazards of melamine board topcoat
1. Melamine board is an artificial board, and glue will inevitably be used during the production process. Therefore, melamine board will release harmful substances such as formaldehyde; if formaldehyde exceeds the standard, it will have a certain impact on the human body.
2. Melamine is a high-strength resin with low toxicity. It will not harm human health as long as it is not taken orally. After curing, it generally does not cause any harm to human health. Volatile toxic substances.
3. Therefore, melamine veneer will not add toxic and harmful substances to the board.
4. Is melamine harmful in cosmetics
1 Melamine, commonly known as melamine, protein, and melamine, is a triazine nitrogen-containing heterocyclic organic compound that is used as a chemical raw material. It is a white monoclinic crystal, almost odorless and slightly soluble in water.
2. Melamine is the trimer of cyanamide. When the resin made of it is heated and decomposed, it will release a large amount of nitrogen and can be used as a flame retardant and water-reducing agent. Agents, etc. Because it is harmful to the human body, it cannot be used in food processing or food additives. Do not use melamine in cosmetics as it is harmful.
5. The hazards of wardrobes made of melamine boards
3 Amine board, the full name is melamine resin impregnated paper veneer artificial board, some people also call it melamine board, or tricyanide board for short. Unqualified melamine boards may cause harm to the human body:
1. During the generation process of melamine formaldehyde resin, there is noThe formaldehyde involved in the reaction exists in the form of free formaldehyde and will be gradually released later. This type of formaldehyde pollution content is not large, and the relative release cycle is not too long. Generally, the release is relatively large in the first half a year or so, and the release amount is greatly reduced after half a year. If the quality is not up to standard, the formaldehyde content may be high and the release cycle will be extended.
2. The skin of melamine board furniture will also emit a unique odor. Not all odors are poisonous and harmful substances, but because I rarely come into contact with this unique odor in my daily life, it makes most people feel uneasy and physically uncomfortable.
3. The difference between the quality of melamine boards lies in whether, in addition to the free formaldehyde in the melamine formaldehyde resin, the formaldehyde in the base material will be released through the melamine facing. When exposed to the air, the sealing performance of the melamine board skin determines the amount of formaldehyde released from melamine board furniture.
6. Is melamine board toxic? What material is melamine board made of
1. Answer: Melamine board is not toxic. Melamine board is made of resin.
2. Melamine is a high-strength, high-hardness resin with basically no volatile harmful components after curing. Melamine veneer is a panel paper impregnated with melamine glue. It is cured by high temperature and high pressure, so melamine veneer is environmentally friendly.
The article ends here. If the hazards of melamine and the safety range of melamine shared this time have solved your problem, then we are sincerely happy!
