MP Large Processing Smoke
Problem Phenomenon
During MP processing, smoke and large amounts of volatiles overflow from the vent
Cause Analysis
Low-molecular volatiles in MP evaporate at processing temperature; additives decompose to produce smoke; insufficient exhaust system
Solution
1) Lower processing temperature to reduce volatilization; 2) Increase exhaust capacity of the exhaust system; 3) Select low-volatility raw material grades
Key Takeaway
Large smoke is caused by evaporation of volatiles; lowering temperature and exhausting are key
