HEAT SOAKED THERMALLY TEMPERED GLASS
Heat Soak Test is take advantage of Heat Soak Test system to detect the occasional occurrence of nickel sulfide (Nis) inclusions in tempered glass. Under strictly controlled temperatures, high-temperature β-Nis converts to low-temperature β-Nis which accompanies a 2-4% expansion in volume and causes the glass to break if the inclusion is located at a tensile stress. The test reduces the frequency of spontaneous breakage of tempered glass after installation.
Characteristic:
· The IPC full automatic control, guaranteed quality.
· Reduces risks of spontaneous breakage of tempered glass
· Increase strength and safety
Specifications:
· Thickness:3mm-19mm
· Max. size:118”×315”(3000mm×8000mm)
