Practical Tips for Molding Long Fiber Reinforced Polymers
2. Sizing section
The glass fiber is applied from the settling section to the conveying process of the conveyor belt, and the adhesive is applied. The settling section needs to be kept clean and dry. Combining the powders is carried out by two applicators of powder binders, and a series of demineralized (distilled) water sprays.
On the Fiberglass matt，the upper and lower sides, lightly spray with distilled water, this operation is a necessary step for better adhesion of the adhesive. Special powder applicator ensures powder distribution. A vibrator between the two applicators enables powder transfer to the underside of the felt.
