Application Of Melamine Powder

—— TAINO CHEMICAL ——
Melamine can be found in many things of our daily life. Some applications might be more familiar than others, but they 
all have in common that its unique properties help to make our life easier, more comfortable and safer.
Melamine in Laminates​​​​​​​
A decorative film layer (like a wood grain, solid color, or pattern) impregnated with a melamine resin that consists of melamine and formaldehyde (MF resin) is attached to a wooden substrate like fiberboard or particleboard core materials. The resulting products are used in furniture, counter tops, walls, floors, and elsewhere. The contained melamine is adding properties like heat, water and chemical resistance to the end product. Also antibacterial properties are included, making melamine high-pressure or low-pressure laminates the ideal choice for e.g. kitchen counter tops.
Melamine in wood adhesives​​​​​​​
The wooden substrates mentioned above also contain melamine – plywood, particle boards (PB), medium density fibreboards (MDF) as well as high density fibreboards (HDF), oriented strand boards (OSB) or laminated veneer lumber (LVL) are bonded with melamine containing urea-formaldehyde (UF) adhesives. Also here melamine adds its unique properties to the product; it reduces the release of free formaldehyde, improves the water resistance of the boards.
Melamine in Surface Coatings
Especially formulated melamine resin systems are used to produce highly durable coatings. This includes clear finishes for paper, fabrics, wood and metals. By pigmenting the resin systems opaque enamel finishes can be obtained. You find them on refrigerators, washing machines, hospital equipment and kitchen utensils where they show their strengths: chemical and water resistance and mechanical properties like scratch resistance.
One popular application is within the automotive industry. MF resins in coatings help to reduce solvent emissions and thus have a positive impact on the environment. 
Melamine in Moulding Compounds​​​​​​​
Melamine resins are strongly thermosetting and can be moulded into a variety of products for our daily life. The moulds are heat-resistant, odour- and tasteless as well as non-conductive. By adding pigments to the resin, various color and combinations thereof are possible. Final moulding products include house
hold appliances, table- and dinnerware, utensil handles, electric sockets and much more.​​​​​​​
Melamine in Textiles and Paper​​​​​​​
Applied to textiles, MF resins improve wrinkle resistance and add flame-retardant properties. Paper treated with melamine is more resistant to wrinkle and impregnated against moisture. Best example are banknotes – despite years of intensive use, they do not wrinkle much and also survive the washing machine.
Other applications​​​​​​​
Flame retardants 
It is mainly used in specialized paints, textile products like firefighting apparel, and in flexible urethane foam that is used in the furniture and bedding industry as well as in electronics products. 
Concrete plasticisers
Melamine also enters the fabrication of melamine poly-sulfonate used as a superplasticizer for making high-resistance concrete.

Featured Melamine Powder

Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong alkali liquor, melamine will hydrolyze---amidocyanogen will be slowly replaced by hydroxyl, thus generate cyanuric acid diacid amide, cyanuric acid monamide, and cyanuric acid. Among them, the reaction of melamine and formalin is the most important part.

Manufacturing Process

—— TAINO CHEMICAL ——

How to make melamine?

The urea method has low cost and is widely used. Urea uses ammonia gas as carrier, silica gel as catalyst, boils at 380-400℃, first decomposes to generate cyanic acid, and further condenses into melamine. The generated melamine gas is cooled and captured to obtain a crude product, which is then dissolved to remove impurities and recrystallized to obtain a finished product. The production of melamine by the urea method requires about 3800KG of urea and 500KG of liquid ammonia per ton of product.

Melamine production process
2
Urea-dissolution
Urea dissolution
The granular urea is heated with steam, becomes liquid, and flows to the storage tank by itself.
3
Liquid-and-urine-circulation
Liquid and urine circulation
liquid and urine circulate between the storage tank and the washing tower to wash the process gas and provide power for the reactor feed
4
Finished-product-packaging
Finished product packaging
The separated triamine is transported to the finished product silo through a pressure screw machine and a Roots blower, and is packaged by a large and small packaging machine before entering the warehouse for sale.
5
Circulation-of-process-gas
Circulation of process gas
The process gas after separation of melamine is pressed by the air-conditioning fan and then enters the washing tower. After the circulating liquid and urine is washed and cooled down, the unreacted liquid urine and unreacted melamine are recovered, and most of the gas enters the crystallizer. To promote the crystallization of triamine gas, a small part of the gas enters the tail gas absorption tower, and the rest of the gas enters the reactor after being pressurized by the carrier compressor.
6
Triamine-generation
Triamine generation
Anhydrous urea is heated by molten salt under the action of a catalyst to generate gaseous triamine, which is cooled by the guiding liquid and filtered by a filter, and then enters the crystallizer. After gas-solid separation, triamine is obtained.
