Our high quality melamine powder is non toxic and odorless crystalline powder, which can dissolve in glyceline,
pyridine,heat ethylene glycol, acetic acid and formaldehyde.Melamine powder is difficult soluble in the ether, benzene and tetrachloromethane.It will sublimate when heated, heated slongly it will decomposite.
Melamine
powder in
methanol solvent by dicyandiamide, at **0 ℃ and ammonia
reaction.This
method requires ***0kg dicyandiamide (*8%) and *0kg liquid
ammonia per ton of product.Compared
with this method, urea method has low cost and is widely
used.Of
urea to ammonia as the carrier, silica gel as the catalyst, the
reaction at ******0 ℃ temperature boiling, first decompose
generate cyanate, and to further generate melamine
condensation.Three
polyamine gas generated after cooling to capture the crude
products, and then through melting, removing impurities,
recrystallization have to finished products.Urea
production of melamine products consumption per ton urea is about
***0 kg, **0 kg of liquid
ammonia.
