Process belts for impregnation in fiberglass mat production
Glass fibers are produced to various specifications in order to meet the requirements of different industries, for example for roof shingles, flooring, and many other technical applications. The glass fibers often differ greatly in terms of their fiber length and thickness, depending on the product properties required. The combination of the mesh size and the open area of a process belt is important here.
Both fiber entanglement and fiber loss must be avoided. At the same time, good dewatering performance is required from the binder/impregnation medium, the viscosity of which can vary greatly depending on its composition. In order to satisfy the process requirements, GKD offers a range of different process belts which can be selected together with the customer on the basis of their fiber and binder specifications.
The selection of the process belt specification has a significant influence on the smoothness of the production process. The mesh size, the number of contact points per unit area, and the web structure all affect the structure of the end product. The process of fiberglass mat production is complicated by the ever-increasing number of variants in binder compositions with widely differing properties. High viscosity of the binder, for example, leads to poorer dewatering performance of the impregnation belt. GKD process belts for fiberglass impregnation are produced using a non-marking endless woven seam for cantilever installation.
