1, product description,
Tempered glass could have spontaneous breakage without receiving any external force, which is the nature of tempered glass. The reason co
mes from nickel sulfide inside the glass. Nickel sulfide is α~Nis in high temperature during the heating section of tempering procedure, when cooled rapidly in cooling section, there is no enough time for it to turn into β~Nis of low temperature. The morphic transformation will last for a dozen years after the tempering glass is installed, and this transformation can lead to volumetric expansion, damaging glass internal stress balance, which will eventually bring about spontaneous breakage.
Heat soak furnace is assistant equipment to tempering. Upon completion of glass tempering procedure, the glass is tested in the heat soak furnace to ignite those tempering glass with potential spontaneous breakage in advance, eliminating rudimental Nickel sulfide and to avoid breakage happening after installation. This increases the safety and reliability of buildings. The machine is characterized with computer in-process monitoring and controlling, multi curve display, data storage, record check and curve printing. This machine can be extended to be used in drying low frit heating and pre-pressing of bending lamination glass. The machine can be customized.
2, Features
- Computer control and monitoring, multi-channel real-time display, data storage and query and printing.
- The heat soaking oven can work as low-temperature glass glazing oven or curved laminated vacuum pre-pressing oven. Custom design is available according to client's specific requirements.
