Toxic gases released during PTFE sintering

During the sintering process, the polymer decomposes and releases toxic gases such as HF and COF₂. This problem is relatively common in sintering molding production and needs to be comprehensively analyzed and solved from multiple aspects of material, process, and equipment.

(1) Temperature parameter aspect: When the temperature exceeds 400℃, PTFE begins to decompose significantly thermally; temperature deviations directly affect the physical and chemical state of the material and the reaction process. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Deviations in the control of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment accuracy and maintenance status affect the stable execution of process parameters.

(1) Process control: Strictly control the sintering temperature not to exceed 380℃, establish an online monitoring mechanism, set upper and lower parameter limits and implement alarm management. (2) Implementation measure: Equip the oven with an exhaust system and tail gas treatment device, formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (3) Implementation measure: Strengthen ventilation and gas monitoring in the operation area., formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (4) Preventive measure: Establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem needs to be comprehensively analyzed from multiple dimensions of material, process, equipment, and operation, and solved by systematically optimizing process parameters and the quality control system.
