Resin solvent residue in wet layup

Problem Phenomenon
After lamination with solvent-based resin, residual solvent in the product causes bubbles or odor. 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: solvent not fully volatilized after layup before entering curing; this factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: high lamination sealing trapping solvent; 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) Implementation measures: let stand for sufficient time after layup to allow full solvent volatilization; formulate specific operation plans based on actual production conditions and verify implementation effects. (2) Material selection: use solvent-free resin systems; establish material selection evaluation standards and determine the optimal solution through comparative tests. (3) Implementation measures: lay breathable peel ply., 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.
