Gas produced by decomposition during PAR '2079851475616104452
Fenómeno do problema
The material decomposes during processing, producing odorous gas.
Análise das causas
The processing temperature is too high >320°C; the carbonate bonds in PAR decompose to produce low molecules such as CO₂ and phenol.
Solução
Strict temperature supervision not exceeding 320°C; minimize the barrel residence time; forced exhaust ventilation.
Conclusão principal
PAR decomposition gas needs environmental control.
