Glass Bridge (Borosilicate glass)
Raw Material
boric acid to produce boron trioxide
silica from silica glass
sodium oxide from sodium carbonate
aluminium oxide from aluminium hydroxide
titanium oxide
laminated by using Sentry Glass Plus(SPG)
Processing
float glass process
batching
melting and refining
float bath
annealing
5.quality checking and automatic cutting
Lamination Process
SGP interlayer
greather security from threats
higher durability in elevated temperature
higher tear strength
higher toughness
higher rigidity than PVB interlayer
protect from UV radiation
Insulates sound by 50%
Higher transparency
Method
Dry Method (Preferred)
Wet Method
others method
used stainless steel
Used glass bottom panel
Used Girder
problem solving (Cracking of glass)
internal cracking
nickel sulphite inclusion
solved by tempering
air bubble
solved by adding refining agent
external cracking
windshield repair kit
cyanoacrylate glue
rebuilt
prolong the bridge lifespan by limiting every entrance of passanger
Advantage of Borosilicate glass
high thermal resistivity
high yield strength and flexural strength
resistance to chemical
high transparency
radiation shielding properties
