Herein is described a process for drying wet glass fibre forming packages, the process comprising: providing a wet glass fibre forming package comprising a strand of glass fibres with an aqueous sizing applied to the glass fibres; and subjecting the wet glass fibre forming package to microwave radiation having a frequency in the range of about 750 to about 1050 MHz.

A heating system is provided having a plurality of heated zones, with at least a first zone and a second zone. The first zone receives variable input moisture fiberglass over a first conveyor system and comprises a first compression system above the first conveyor system. Each zone has a fire box at the top and an exhaust stack. Heated air is up drafted through the bottom of the first zone, where the heated air flows from the bottom through the conveyor belt, through the fiberglass media, through the tensioned compression chain, and out the exhaust stack of the first zone. The first zone establishes fiberglass loft, with the second zone providing cure of the fiberglass.

A gypsum product with a fortified glass fiber mat is provided in which the glass fiber mat is strengthened by crystallization of salt crystals on the glass fiber mat prior to the glass fiber mat use in the gypsum product. Methods for making a glass fiber mat saturated with salt crystals and gypsum products with the glass fiber mats are provided as well.

The present invention relates to a heat conservation-insulating material which is coated with a UV film and has maximized heat efficiency, wherein: the material uses a thermosetting water-soluble acrylic adhesive to ensure the minimum uniform coating film thickness required for corrosion prevention of a pipe and strength reinforcement during curing and allow easy installation with flexibility and sufficient working time before the installation; and a surface of the insulating material is UV-coated and thermosetting-coated by dual-cure curing method so that even a part where light or ultraviolet rays cannot penetrate can be cured, a heat conservation-insulating material having vivid colors can be obtained even when dye and pigment are added to realize various colors, and the cutting processability is excellent to enable a uniform coating on various surfaces, such as metal, plastic, glass, ceramics, stone, wood, and various building materials, or even on sharply bent shapes.
