Soft foam sponge products show "tofu dregs" foam

The foam body has a powdery loose structure without elasticity. This problem is relatively common in foam molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Process factor: isocyanate-water foaming reaction too strong while gelation reaction severely insufficient; this factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: severe catalyst imbalance; this factor affects the '2079851475616104453 and final quality of the product. (3) Material aspect: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) Process aspect: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (5) Equipment aspect: equipment precision and maintenance status affect the stable execution of process parameters.

(1) Formulation adjustment: reduce water (chemical foaming agent) and amine catalyst dosage, adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (2) Formulation optimization: increase tin catalyst dosage to accelerate gelation., determine the optimal addition amount through small-batch tests, and verify the impact on the comprehensive performance of the product. (3) Process optimization: determine the optimal process parameter window through systematic tests and establish standardized operating procedures. (4) Quality control: strengthen process monitoring and product inspection, and establish defect early warning and traceability mechanisms. (5) 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.
