Gas produced by decomposition during PAR '2079851475616104452
Fenómeno del problema
The material decomposes during processing, producing odorous gas.
Análisis de la causa
The processing temperature is too high >320°C; the carbonate bonds in PAR decompose to produce low molecules such as CO₂ and phenol.
Solución
Strict temperature supervision not exceeding 320°C; minimize the barrel residence time; forced exhaust ventilation.
Conclusión clave
PAR decomposition gas needs environmental control.
