When users purchase, they should check that the surface is smooth, crack-free, and free of impurities, and the logo is clear and standardized.
    Preparation Method
    The preparation of melamine is originally made of urea as the main material. Urea is first put into a kettle, heated until melted, and the temperature is maintained at a high temperature. A fusion reaction is carried out to obtain an intermediate. At this time, catalysis is applied, or zinc oxide is used, or aluminum oxide is used to promote molecular rearrangement. The reaction is gradual, and melamine crystallizes are precipitated. In the meantime, ammonia is released, and it is better to escape as soon as possible to obtain a complete reaction, so that impurities do not grow. Changes in temperature and pressure must be precisely regulated to ensure that the retention rate and purity are both high. The process is simple and clear, and a closed device is used to prevent loss. The final product is obtained, which is washed and dried to remove residual gas. Melamine is formed. The whole process, the reaction path depends on the catalytic mechanism, weak urging will result in more by-products, strong urging will result in smooth conversion, and the principle of chemical industry lies in this.
    Chemical Reactions & Modifications
    Melamine, the molecular formula C < unk > H < unk > N < unk >, is strong and white, but its chemical properties are very active. It often interacts with formaldehyde to form melamine formaldehyde resin. This is an addition-condensation reaction, which first forms a methanol-based derivative, followed by cross-linking and densification. Its modification method is multi-terminal, or it is blended with epoxides to toughen and resist impact, or carboxyl and hydroxyl groups to impart moisture absorption and fire resistance. It can be used in combination with phosphorus and nitrogen-based flame retardants, and the flame resistance is beneficial. If nanoparticles and ceramic powders are doped during polymerization, their thermal stability and mechanical properties can be improved, which should be used for construction and appliance coatings. However, by-product residues occasionally cause poisoning, so the purification process must also be paid attention to. The reaction and modification of melamine has become an important issue in materials engineering, and chemical products are essential.

    What material is Melamine?
    Melamine is an organic nitrogen heterocyclic compound. Its name is derived from the Latin melam, molecular formula C
    H < N >, which is white crystalline in shape, light and slightly bitter in taste, tough in nature and high temperature resistance. It is derived from three elements of nitrogen, carbon and hydrogen, contains three pairs of amino groups, which are embedded with the triazine skeleton. The structure is compact, the chemical properties are robust, and it is difficult to dissolve in cold water and organic solvents. Melamine is usually formed by the condensation of urea at high temperature. It is both easy to produce and inexpensive. The process has become more and more refined in modern times.
    Its chemical properties are special, and it can undergo a condensation reaction with formaldehyde to form Melamine-formaldehyde resin. This resin is colorless and transparent, with excellent mechanical strength, smooth surface, refractory and corrosion-resistant, and good insulation. Resins can be made into tableware, sanitary ware, decorative panels and electrical parts, and can also be used as additives in paints, adhesives, papermaking, and textiles. Because of its white appearance, and can be doped with pigments and decorated with colors, since the 1940s, Melamine tableware has been widely circulated in the world and is especially favored.
    However, Melamine itself is non-toxic, but its products such as poor craftsmanship or poor storage can release trace formaldehyde and free melamine in case of high temperature, strong acid, or long-term immersion in hot water. If people accidentally eat high concentrations of melamine, or mix it with dairy products, pet food, etc., it will damage the kidneys and even cause disease. It is used in food utensils and containers for this reason. Strict regulations should be followed to prevent abuse.
    In short, melamine is a nitrogen heterocyclic compound with flexible chemical reaction, which benefits industry and agriculture, and is used in the daily life of the people. However, its application is related to personal safety, and its safety must be taken into account. Only by following the law can it be achieved without harm.
    What products is Melamine mainly used for?
    Melamine, also known as "melamine", has strong and heat-resistant properties, stable chemical properties, and is widely used in modern processes. Tracing back to its origin, melamine is an organic compound with high nitrogen content, white crystalline powder, easily soluble in alcohols and some organic solvents, but difficult to dissolve in water. Its properties are specific, so the application field is particularly broad.
    First in plastic manufacturing. Melamine and formaldehyde are used together to synthesize melamine formaldehyde resin. This resin is hard and dense, wear-resistant and anti-corrosion, and is used to cast daily utensils, such as bowls, plates, cups, spoons, dinner plates, etc. It is brilliantly colored, resistant to drop damage, and has no peculiar smell. It is deeply favored by the world. It can also be used for electrical enclosures, switches, sockets and various insulating parts. It has the advantages of insulation and heat resistance and is widely used in industry. Plate composite also relies on melamine resin, which is coated with wood surface to make decorative panels. It is rich in color, scratch-resistant and moisture-resistant, and is more attractive for decoration and furniture.
    The second is adhesive. Melamine resin is commonly used as adhesive in paper and textile pulp and wood material boards. Water resistance and durability are better than commonly used urea-formaldehyde resin. It is used to make moisture-proof high-quality wood-based panels. It can be seen in the flooring, furniture and construction industries.
    The third is flame retardant. Melamine releases nitrogen and is non-flammable. It is often added to plastics, rubber, coatings, etc., to make its products fire-retardant and flame-retardant. It not only improves product safety, but is especially suitable for special fields such as circuit boards, home appliances, and transportation.
    In addition, it is also used as an additive in papermaking, textiles, and other industries. It can give paper products moisture resistance, oil resistance, and stiffness. It can also be used in fiber processing to enhance the heat and chemical resistance of fabrics. Some diesel additives and leather protective agents also use melamine as the main ingredient.
    However, although melamine has a wide range of uses, it should not be used in food additives. It is harmful to human health when entering food. It has caused serious problems in the world, and the world should be cautious. Therefore, its rational application is guided by science and technology, and regulations can be used to benefit the world without harm.
    In summary, melamine is indispensable in many fields such as household use, industrial production, building decoration, and flame retardant materials, and is an essential material for modern chemical industry.
    Is Melamine Harmful to the Human Body?
    Melamine is a chemical substance that is widely used in industry, especially in the manufacture of plastics, adhesives, and heat-resistant appliances. However, it is not a food. Occasionally, there are profiteers. Due to its high nitrogen content, it is mixed with dairy products and feeds to pretend to be rich in protein. If people ingest melamine, there may be no immediate abnormalities at first, but the damage will gradually appear over time. In the human body, it can combine with the components in the kidneys, condense into stones, block the urinary tract, resulting in poor urination and severe pain in the lower back and abdomen. In most cases, it will eventually lead to kidney failure, which is unbearable. Children are weak and particularly vulnerable, and if ingested in small amounts, it can also be fatal.
    The toxicity of melamine is not as severe as arsenic, but it will eventually erode for a long time. Some medical scientists have tried it on animals and found that the bladder and kidneys are damaged. It is difficult for the human body to metabolize it, and it will accumulate for a long time, and the disaster will deepen. Or is there a way to ask for a cure? If you have ingested it, you must seek medical attention immediately, and perform the method of removing stones and protecting the kidneys. If it is not contaminated, it is advisable to put an end to this product in the diet.
    In countries with legal laws, melamine is fasted. Therefore, if the product is detected in food, merchants will be severely punished, and the public should also be vigilant. Food is beautiful in nature, do not believe in false packaging, and it is advisable to clearly detect the origin of raw materials. Although melamine can be used in utensils, it should never be used as an edible product. If eaten by mistake, it will cause physical discomfort, and it will cause
    To sum up, melamine is a scourge to mankind. Although it is widely used, it will cause harm if it involves food. A gentleman should stay away from it, so as not to repeat the same mistakes of the race.
    Can Melamine withstand high temperatures?
    Melamine, known today as Melamine, is an organic compound with a white crystalline quality and a slightly bitter taste. Considering its properties, melamine has strong properties, is difficult to dissolve in water, and has relatively stable chemical properties. In terms of its use, it is widely found in plastic tableware, adhesives and heat-resistant materials. However, when it comes to "high temperature resistance", the rationale must be discussed in layers.
    First of all, melamine has a very high melting point, nearly 350 degrees Celsius, which is much higher than ordinary organic matter. Therefore, the system is less prone to deformation and cracking due to boiling water or hydrothermal solution. However, although the melting point is high, when melamine encounters high temperature, if it exceeds 200 degrees Celsius, it will gradually explain ammonia and other phenomena. Under the condition of its polymer, melamine resin, the quality is strong and beautiful at room temperature. Only when it encounters a hot topic, the resin structure is at risk of disintegration, and harmful substances can also be released, which is unfavorable to human health. From this perspective, although the body of Melamine has excellent temperature resistance, its application is mostly in the form of resin. If it is cooked at high temperature for a long time, or microwaved or baked, it is easy to age over time, release melamine monomer, or even decompose under heat, gradually losing its original toughness.
    From the above, it can be seen that although Melamine can withstand high temperature, it is actually better than most common organic materials. However, with its synthetic utensils, it is not the best product that can withstand hot topics for a long time. In case of fire and microwave abuse, it cannot be listed with iron and porcelain materials. Edible utensils made of melamine should be used for frying and oven roasting at high temperature. A little heating is acceptable, but they should not be placed in boiling water or extremely high temperature for a long time. In this way, its physical properties can be guaranteed not to deteriorate, and it can also be prevented from volatilizing harmful substances, which is safe for people. Therefore, the answer is: Melamine is strong and temperature-resistant, but it should be used to a limited extent. If you want to withstand high temperatures for a long time, it is better to use gold and stone ceramics.
    How are Melamine products cleaned and maintained?
    Melamine utensils are strong and smooth, and are widely used by the world. If they are used for a long time, if there is no good way to clean and maintain them, they are prone to dirt or damage their color. The methods for cleaning and maintenance are as follows:
    After each use, it is advisable to wash with warm water. Add a little neutral soap to the water and wipe the surface with a soft cloth. Do not wipe with wire brushes and rough objects, for fear of surface wear. If there are stubborn stains, you can mix warm water with a small amount of soda powder, or dip it in vinegar sauce and then brush it off with a soft cloth. If the utensils are stained with oil, it is advisable to dip a paper towel in the oil first, and then wash them with warm water soap.
    Do not clean with substances containing bleach or strong acids and alkalis. Cover such agents for a long time, it will corrode the surface and make the device lose its luster. Microwave ovens and open flames are not suitable for them, and they may be deformed or cracked by high temperature. Store on weekdays, it should be protected from hot sun exposure and away from heat sources. Place in a ventilated and cool place, and the device should be kept as new from long-term. If stacking is required, it is recommended to pad the device with a soft cloth or paper to prevent friction and scratching.
    Melamine utensils should be used for food, and should not be used to hold things that are too acidic or overheated. If there is a peculiar smell, you can wash it with lemon slices or tea leaves. If you see cracks or gaps on the surface, you should stop using them, so as not to mix the fragments into the food and endanger your health.
    In short, you must use a gentle method to treat it. It is far from bad things that will be damaged. If you are always clean and properly stored, you will be able to prolong its life and maintain its beauty. Melamine utensils are the best utensils for modern life. Only by properly cleaning and maintaining them can you enjoy their use for a long time.
