Tempered Laminated Glass Distortion

Hi i made a 21 5mm tempered laminated glass for a customer to use for his client s swimming pool.
Tempered laminated glass distortion. Fine scratches no longer than 25mm. Distortion effects in tempered glass have been a persistent problem. Such as laminated glass should be considered. Glass intended to be used primarily for architectural glazing products including.
Distortion heat treated toughened tempered heat strengthened laminated 1. Optical distortion in laminated glass with heat strengthened glass substrates laminated glass is produced by bonding a plastic interlayer between two or more panes of glass under heat and pressure in an autoclave. 4 2 2 moiré interferometry method. Tempered glass may to have glass roller wave distortion and bow caused by the strengthening process.
Is there a particular type of tempered glass that would have the least amount of distortion for making a full length two way mirror in a large picture frame out of. Cooled the glass retains this. The result is a durable high performance glazing composite material which if broken tends to retain glass. Annealed glass leaves the fl oat line with a fl atness that has been well accepted.
With both heat strengthening and tempering distortion is a possibility. Optical image distortion occurs in glass. Coated glass igus laminated glass mirrors spandrel glass or similar uses. The procedure is mainly useful for measuring the roller waves of flat architectural glass but can also be used for inspection of laminated glass and tempered curved glass.
Point blemish linear blemish content associated distortion dimension squareness reflectance and transmittance. The following astm c1048 chart contains information on the allowable bow and warp based on the glass thickness length and width. The amount of the distortion can be reduced by using heat strengthened in lieu of fully tempered glass. The glass will be classed as acceptable if the following are neither obtrusive nor bunched together.
It is accepted that a small amount of distortion may be visible through. From the glass as well as the distance of the viewed objects to the glass are critical in quantifying the perceived visible distortion. Toughened and toughened laminated glass as used in iq installations is a processed glass. Introduction while distorted images seem to be variable subjective and difficult to quantify they can be.
When a sheet of fl oat glass is heated to the softening point in a tempering furnace the glass fl exes sags and loses its initial fl atness. Upon breaking the pattern is unique in that it forms small cube like pieces which may or may not fall out at the time of impact but have virtually no residual strength as a glass unit when faced with subsequent load.
