Moisture/contamination in reinforcement material
Problem Phenomenon
Glass fiber or fabric contains moisture or is contaminated with oil, causing poor interlayer bonding.
This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.
Cause Analysis
(1) Process factor: poor fiber storage conditions causing moisture absorption or contamination; this factor affects the '2079851475616104453 and final quality of the product.
(2) Process factor: grease contamination during handling; this factor affects the '2079851475616104453 and final quality of the product.
(3) Material aspect: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality.
(4) Process aspect: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions.
(5) Equipment aspect: equipment precision and maintenance status affect the stable execution of process parameters.
Solution
(1) Process control: control warehouse temperature and humidity; establish an online monitoring mechanism, set parameter upper and lower limits and implement alarm management.
(2) Material selection: fully dry fibers before use; establish material selection evaluation standards and determine the optimal solution through comparative tests.
(3) Implementation measures: operators wear gloves to prevent contamination., formulate specific operation plans based on actual production conditions and verify implementation effects.
(4) Preventive measures: establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.
Key Takeaway
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.
