Melamine particle size issue
Thread Content
Please discuss whether it is better for the triamine to have a larger particle size or a smaller one. For triamine users
The next step for triamines is to react with formaldehyde to produce glue; does a smaller particle size result in a faster reaction? I think smaller is better. Downstream processing is completely beyond my expertise; it’s just a guess~~
“It is only for the high-pressure method and the two-step method that the finer the melamine produced, the greater the difficulty. The higher the cost. ” Let’s discuss only this sentence: The production difficulty or cost of the high-pressure method used in European technology is higher than that of the two-step method, but the products obtained using the high-pressure method are coarser and have larger particle sizes, which seems to differ slightly from what the experts said. In my opinion, the particle size of the product is related to the crystallization process. In the high-pressure method, the particle size is achieved by forming nuclei through high-flow cyclic impact in the crystallizer, followed by drying in a dryer to produce the final product; unlike gas-phase cooling crystallization, this results in differences in particle size.
Personally, I think the finer the granularity, the better; customers would like that too. If the particle size is too small, the requirements for the filter increase as well; does this lead to higher filtration costs?
