A STUDY ON EFFECT OF UV - RAYS IN A NEWLY DEVELOPED GLASS USING NANO FILLERS BY WINDSHIELD GLASS MANUFACTURING PROCESS

In idea of enhancing UV rays filtering properties in windshield glass in automobiles industries this study was experimented with Nano fillers Silica (SiO2) and Alumina (Al2O3).These two Nano fillers were primarily used as a binding material between PVB (Polyvinyl Butyral) layers of two pairing windshield glass. Nano fillers of SiO2 and Al2O3 weighing 2gms each are manually added to the layer of the glass and this sandwiched glass goes through a heat treatment in a furnace at 65°C-70°C, along with Nip roller pressure maintenance of 0.6 Mpa to 0.7 Mpa with a glass thickness of each 2.5mm, PVB thickness of 1.52 mm, and then the laminated glass rolling out was pressed and later taken into an autoclave glass steam binding process, where the glass can bond with Nano fillers up to 4 hours as a post operation. From the newly fabricated glass, Samples with dimensions of 20x45 mm and a thickness of 5 mm were prepared. To evaluate the UV shielding properties of these Nano filler fabricated glass, these samples were tested for optical clarity and UV penetration with wavelengths ranging from 280nm to 400nm.
