Sticky surface (incomplete curing)

The product surface is still sticky after demolding. This problem directly affects the mechanical properties and surface quality of the product, and causes entire batches of products to be scrapped in severe cases. This defect affects the appearance quality of the product and reduces the market competitiveness of the product.

(1) Temperature parameter aspect: insufficient curing temperature or curing time; temperature deviation directly affects the physicochemical state and reaction progress of the material. (2) Formulation control aspect: incorrect curing agent or catalyst ratio; component ratio deviating from the design value causes abnormal chemical reaction or physical state. (3) Temperature parameter aspect: ambient temperature too low, leading to insufficient reaction kinetics or deterioration of material fluidity, affecting the normal progress of the '2079851475616104453.

(1) Equipment maintenance: check whether the curing cycle is sufficient; formulate regular inspection and maintenance plans to ensure the equipment is in optimal working condition. (2) Parameter adjustment: extend hot pressing time or increase hot pressing temperature; it is recommended that each adjustment range be 5-10°C, while monitoring product quality changes to avoid new defects caused by excessive temperature. (3) Implementation measures: confirm accurate curing agent/catalyst ratio; formulate specific operation plans based on actual production conditions and verify implementation effects. (4) Post-treatment: perform post-curing treatment., formulate a reasonable post-treatment temperature curve to eliminate internal stress and stabilize product dimensions. (5) Preventive measures: establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.

The core of poor curing problems is that chemical reaction conditions do not meet requirements; formulation ratios and curing process parameters need to be precisely controlled.
