Chemical foaming agent residue causing acid corrosion

Decomposition residues of azodicarbonamide (AC) foaming agent corrode molds or metal inserts. This problem is relatively common in foam molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Material stability aspect: AC foaming agent decomposes to produce corrosive residues such as ammonia and cyanuric acid; molecular chain breakage causes irreversible decline in material performance. (2) Material aspect: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: equipment precision and maintenance status affect the stable execution of process parameters.

(1) Material selection: use acid absorbers to neutralize residues; establish material selection evaluation standards and determine the optimal solution through comparative tests. (2) Implementation measures: perform cleaning post-treatment after foaming; formulate specific operation plans based on actual production conditions and verify implementation effects. (3) Material selection: select foaming agents with non-acidic decomposition residues as substitutes., establish material selection evaluation standards and determine the optimal solution through comparative tests. (4) Preventive measures: establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.

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