PVC Pipe Sizing Adhesion
Problem Phenomenon
Material sticks to sizing sleeve, pipe surface pulled damaged with scratches.
Cause Analysis
Exudates accumulate at sizing sleeve entrance; lubricant exudation aggravates; high melt temperature intensifies volatilization; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience.
Solution
①Optimize lubrication system, reduce exudation of incompatible external lubricants; ②Regularly clean sizing sleeve entrance buildup; ③Control melt temperature within safe window; ④Polish sizing sleeve entrance to reduce adhesion; ⑤Check raw material quality and cleanliness.
Key Takeaway
PVC sizing adhesion = 'exudation management': lubrication balance and melt temperature are key; exudate accumulation is gradual, regular cleaning and formula optimization must go together; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
