high transmittance small diameter quartz glass tube
In general, it is not recommended to pass hydrogen in the tube furnace.
1.Except for the non-hydrogen content in the limit explosive concentration, if you need to use the tube furnace to pass hydrogen with a concentration outside the explosive concentration,
you must take safety measures. Don't stand by people. If you are venting hydrogen, please use stainless steel pipes, because stainless steel has a larger thermal conductivity than quartz,
so the two ends of stainless steel need to be water-cooled, otherwise the O-ring temperature is too high and cannot be sealed.
2. The softening point of the quartz tube is 1270 degrees, and it should not exceed 3 hours when it is used at 1200 degrees.
3. Please place ceramic plugs in the furnace tube when heating, otherwise the temperature at both ends of the furnace tube will be higher,
and the O-rings in the flange cannot accept higher temperatures, resulting in poor airtightness. Conducive to the formation of a balanced temperature field.
4. Keep the furnace tube clean and hygienic. When burning materials, in order to make the furnace tube have a longer service life,
do not put the materials directly on the furnace tube and use a boat-shaped crucible to hold it.
5. When heating, please put alumina furnace plugs in the furnace tube, put 2 on one side, 4 in total, the innermost distance between the two sides of the furnace plug can be about 450mm,
if the furnace plug is not placed, the temperature at both ends of the furnace tube is higher, the flange The O-rings inside cannot accept higher temperatures,
which makes the air tightness poor. Putting plugs on both ends of the furnace tube is conducive to forming a balanced temperature field.
