Environmental Humidity Influence (Moisture-Sensitive Systems)

The product shows bubbles, foaming, or abnormal curing. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Process factors: isocyanates, this factor affects the product's '2079851475616104453 and final quality. (2) In terms of material pretreatment: moisture-sensitive materials such as silicone rubber react with environmental moisture to produce CO₂, moisture vaporizes at high temperatures to produce gas or participates in side reactions, causing internal defects in the product. (3) In terms of material pretreatment: the mold surface or fillers contain water, moisture vaporizes at high temperatures to produce gas or participates in side reactions, causing internal defects in the product.

(1) Process control: control the workshop relative humidity to ≤50%, establish an online monitoring mechanism, set upper and lower parameter limits, and implement alarm management. (2) Implementation measures: store raw materials sealed, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Material selection: fully dry the filler before use, establish material selection evaluation standards and determine the optimal plan through comparative tests. (4) Implementation measures: adopt nitrogen-protected casting., 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.

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.
