Paraformaldehyde production
Thread Content
Paraformaldehyde is an important pesticide intermediate. It uses formaldehyde as raw material and is completed through processes such as concentration, polymerization, and drying. Industry insiders are kindly requested to discuss and exchange paraformaldehyde production processes and common production issues here.
I also want to know about this aspect. How much is the investment to produce paraformaldehyde from formaldehyde? How big is the market for paraformaldehyde? Please give me some advice! Thanks!
At present, most paraformaldehyde in China uses the rake drying method. This method has relatively small investment, but it causes high pollution and a large amount of wastewater treatment. Some large domestic companies use the spray drying method. The investment in spraying is generally 20-30 million, while the rake drying method only costs a few million. However, the single line capacity of the rake type is smaller.
What are the main uses of paraformaldehyde in China?
Is paraformaldehyde mainly due to pesticides? What are the prospects?
Paraformaldehyde is mostly used in the production of glyphosate and amino molding resins.
The use of target drying to produce paraformaldehyde can be discussed, QQ942983021
The working environment of the rake is terrible! Is there any improvement from any manufacturer? Apart from Kaimao, who has this technology for domestic granulation, who else can do it? Please give me some advice.~
