glass sealing “GS-2”in the electric heating tube

1, introduce:
At present, in the Electric heating tube industry, high temperature pipe sealing is adopted the special epoxy resin adhesive made in USA. The epoxy resin adhesive can not resist the high temperature for long time. It only can stand under the temperature of less than 150 0C. But also the epoxy resin is easy ageing under the long term high temperature. It will effect the sealing quality. So sealing is always a problem of the Industry of electric heating tube producing.
Japanese ASAHI has developed the glass circle MG-2 as the sealing material. The glass can be heat-resistant, low expansibility, anti-ageing, high insulation. This raises the safety of the high temperature tube sealing.
Our company is the second company, which develop this glass for sealing successfully in the world. We have tested the capability for more than two years. The stability of its capability was recognized by the best electric heating tube manufacture,
Saosa GS-2 is shaped according the index and technology of the Japan ASAHI MG-2. After testing, GS-2 is replaced of the MG-2 completely. But the cost decline sharply.
