Discussion on the polymerization reaction of polyoxymethylene
Thread Content
The polyoxymethylene technology we use relies on **Fuyi’s technology**. Compared to other manufacturers that also use Fuyi’s technology, we employ a catalyst with a higher concentration – could this be because the pH value of our raw materials is too high? When less catalyst is used (below 35PPM), we often encounter blockages at the reactor’s discharge port here! The proportions of the other raw materials can be just fine. Is there anyone who knows about polyoxymethylene who can explain it?
There must be a problem with the raw material; generally, the amount of catalyst used does not exceed 20 ppm.
Actually, it’s not necessarily due to the raw materials; which catalyst do you use?
Do catalysts from different manufacturers have a significant impact on polymerization?
The catalyst is crucial; definitely, the manufacturer has a big impact
BF3 is basically the same across all suppliers; there isn’t much difference!!
This should be related to the production conditions; after all, there are slight differences in the production processes among different companies.:)
The catalyst has a significant impact; even if the purity of dioxolane and triomethylenetetramine is not sufficient, boron trifluoride can help to address this issue. The key factors are the temperature of the D-425 reactor vessel and the amount of steam used. At a temperature of 125 degrees, there should be no major problems with the product
There are many factors that have an impact; the most important ones are the purity of the raw materials, the design of the reactor, and the quality of the premixer – whether it can achieve uniform mixing
I’m asking based on the original poster’s question: what is the steam consumption per unit of trioxanone in the Fu Yi polyoxymethylene production process? Currently, the steam consumption per unit of trioxane produced by different processes is being compared.
