Paraformaldehyde is a chemical substance. When recycling, it is necessary to understand the physical and chemical properties of this substance, otherwise it is very dangerous.
Polyformaldehyde manufacturers introduce polyformaldehyde as a polymer of formaldehyde. The degree of polymerization of low molecular weight formaldehyde is about 8-12, the solubility of formaldehyde is about 8-12, the solubility of formaldehyde is 80, the formaldehyde odor is intense, the solubility of the polymerization degree n above 12 is 120-170. It dissolves in ethanol, propanol and ether, dissolves in dilute acid and dilute alkali solution, it decomposes quickly when melting. Some mechanical properties of the plastic can not be made into thin films, which can be used as disinfectants, bactericides, and resin and artificial ivory, and can be obtained by polymerization of pure formaldehyde under the alkaline condition (such as HaOH).
Paraformaldehyde manufacturers say polyformaldehyde is made from dehydration and drying of formaldehyde. Its production is carried out in two steps: first, it is heated under negative pressure to remove 37% of the formaldehyde first, and the concentrated aldehyde of 65%-70% is polymerized under the condition of alkaline catalysis and then dried and obtained. It is worth clarifying that in order to reduce the loss of aldehyde. You need to drop the boiling point.
