Fluorinated oligomer fume condensation produced in fluororesin sintering

White waxy oligomers condense in the exhaust pipeline of the sintering furnace, causing blockage. This problem is relatively common in sintering molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Temperature parameter aspect: PTFE slightly decomposes at sintering temperature, releasing oligomers such as hexafluoropropylene that condense in low-temperature pipelines, leading to insufficient reaction kinetics or deteriorated material flowability, affecting the normal progress of the '2079851475616104453. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Implementation measure: Set a high-temperature section (>250°C) in the exhaust pipeline so that oligomers pass through without condensing, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (2) Operation specification: Regularly clean pipeline condensate, Develop standard work instructions for cleaning operations, and perform inspection before each production run. (3) Implementation measure: Exhaust gas is discharged after high-temperature oxidation treatment., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (4) Preventive measure: Establish sound process control standards and a quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of material, process, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
