Slow or No Curing of Silicone Rubber Casting

Two-component addition-cure silicone rubber does not cure for a long time. 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) Process factors: catalyst platinum poisoning (contact with sulfur-containing, this factor affects the product's '2079851475616104453 and final quality. (2) Process factors: tin compounds), this factor affects the product's '2079851475616104453 and final quality. (3) In terms of formula control: wrong ratio, component ratios deviating from design values lead to abnormal chemical reactions or physical states. (4) In terms of temperature parameters: insufficient curing temperature, temperature deviation directly affects the physicochemical state of the material and the reaction progress.

(1) Implementation measures: eliminate poisoning sources, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (2) Material selection: use dedicated containers by category, establish material selection evaluation standards and determine the optimal plan through comparative tests. (3) Implementation measures: accurately measure the A/B component ratio, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (4) Implementation measures: ensure the curing temperature meets requirements., formulate a specific operation plan based on actual production conditions and verify the implementation effect. (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.
