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