Method for producing glass fiber material including steps of sizing and desizing, and equipment suitable for carrying out said method

摘要

In the present invention, molten glass is converted into a glass fiber material by spinning, drawing, sizing, and collecting steps, followed by a step of producing the obtained glass fiber material, followed by thermal desizing. The present invention relates to a glass fiber material manufacturing method and equipment. The fumes from the melting furnace are used in two steps to preheat the combustion reactants from the melting furnace: in the first step the air is heated by heat exchange with the fumes and in the second step hot air and This heat exchange preheats the combustion reactants and then air is used for the glass fiber material de-sizing step.
