The method of the invention is that the resin in a resinstorage pot is executed with ultrasonic-processing continuously in the technical process of resin transfer molding.
本发明的方法是在树脂传递模塑工艺过程中持续对储胶罐中的树脂进行超声处理。

The epoxy resin toughened by the above copolymer has excellent storage stability and, after cured by heating or at room temperature, it has higher shear strength and T-peeling strength.
The result shows that the AKD size emulsified with cationic resin has higher charge density, longer storage life and better sizing efficiency, and also no susceptibility to moulds.
