Cure inhibition effect appears in a certain batch of raw material

A certain batch of raw material cannot cure normally under the same process conditions. This problem directly affects the mechanical properties and surface quality of the product, and in severe cases leads to scrapping of the entire batch.

(1) Process factor: Trace inhibitors or catalyst poisons are mixed in during raw material production, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: The chemical composition changes during storage, This factor affects the '2079851475616104453 and final quality of the product. (3) Formulation aspect: Insufficient curing agent or catalyst dosage, with the ratio deviating from stoichiometry. (4) Process aspect: Curing temperature or time is insufficient, and the reaction conversion rate does not meet requirements. (5) Environmental aspect: Ambient temperature too low or moisture interferes with the curing reaction.

(1) Material selection: Perform a small-sample curing test before using each batch of raw material, Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (2) Implementation measure: Establish a raw material batch traceability system, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (3) Implementation measure: Suspend use of the problematic batch and investigate., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (4) Preventive measure: Establish sound process control standards and a quality inspection system, and regularly review process data for continuous optimization.

The core of the poor curing problem is that the chemical reaction conditions do not meet the requirements; it is necessary to precisely control the formulation ratio and curing process parameters.
