Incomplete Curing of the Product/Long-Term Tackiness

The product surface is sticky after demolding, and the hardness has not reached the design value. This problem directly affects the mechanical properties and surface quality of the product, and in severe cases leads to the scrapping of the entire batch of products.

(1) In terms of formula control: wrong ratio or insufficient amount of curing agent/accelerator, component ratios deviating from design values lead to abnormal chemical reactions or physical states. (2) In terms of temperature parameters: the ambient temperature is too low, causing the curing reaction to be sluggish, leading to insufficient reaction kinetics or deterioration of material fluidity, affecting the normal progress of the '2079851475616104453. (3) In terms of process time: insufficient curing time, improper time control causes the reaction or cooling process to fail to meet process requirements, affecting the final performance of the product.

(1) Implementation measures: accurately measure the amount of curing agent, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (2) Equipment maintenance: check the ratio of the curing system, formulate a regular inspection and maintenance plan to ensure the equipment is in optimal working condition. (3) Parameter adjustment: increase the mold temperature or extend the curing time, it is recommended that each adjustment amplitude be 5-10℃, while monitoring product quality changes to avoid new defects caused by excessive temperature. (4) Post-treatment: perform post-curing treatment if necessary., formulate a reasonable post-treatment temperature curve to eliminate internal stress and stabilize product dimensions. (5) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

The core of the poor curing problem is that the chemical reaction conditions are not met, and the formula ratio and curing process parameters need to be precisely controlled.
