The air pressure in the furnace tube should not be higher than 0.02MPa Due to the high air pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when gas is introduced into the furnace tube. It is recommended to purchase a pressure reducing valve in our company. More precise and safe to use The air pressure in the furnace tube should not be higher than 0.02MPa Due to the high air pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when gas is introduced into the furnace tube. It is recommended to purchase a pressure reducing valve in our company. will be more add precision and safety When the temperature of the furnace body is higher than 1000C, the furnace tube cannot be in a vacuum state, and the air pressure in the furnace tube must be equal to the atmospheric pressure and kept at normal pressure. The gas flow into the furnace tube should be less than 200SCCM to avoid the impact of the cold atmospheric flow on the heating quartz tube . Long-term use temperature of quartz tube < 1100C For the sample heating experiment, it is not recommended to close the exhaust valve and the intake valve at the flange end of the furnace tube. If you need to close the air valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the air pressure indication is greater than 0.02MPa, the vent valve must be opened immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.) The gas flow into the furnace tube should be less than 200SCCM to avoid the impact of the cold atmospheric flow on the heated quartz tube. The long-term use temperature of the quartz tube is < 1100C 0.02MPa, the vent valve must be opened immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.) |
