Cautions

1. When the equipment is in use, the pressure in the furnace tube shall not exceed 0.15MPa (absolute pressure) to prevent damage to the equipment caused by excessive pressure;
2. When used in vacuum, the operating temperature of the device shall not exceed 1000℃.
3. The internal pressure of the gas supply cylinder is high, and when the gas is fed into the furnace tube, the pressure reducing valve must be installed on the cylinder. It is recommended to choose a small pressure reducing valve for test, and the measuring range of the pressure reducing valve is 0.01MPa-0.15MPa, which is more accurate and safe in use.
4. When the temperature of the furnace body is higher than 1000℃, the furnace tube can not be in a vacuum state, the pressure in the furnace tube needs to be equivalent to atmospheric pressure, maintain in the state of atmospheric pressure, to prevent damage to the cavity;
5. The use temperature of high-purity quartz pipe under atmospheric pressure for a long time is ≦1150℃;
6. When heating and sintering, the exhaust valve should be opened to avoid cavity pressure increase when heating and heating, resulting in cavity rupture. If it is necessary to close the air valve to heat the sample, it is necessary to pay attention to the number of pressure gauge. If the pressure of the barometer is within the safe range, if the absolute pressure reverse pressure ≦0.05Mpa or the positive pressure ≧0.15Mpa, the exhaust valve must be opened immediately to prevent accidents (such as cavity rupture);
7. When this equipment is used for high temperature sintering, it must be connected to the water cooler to operate, so as to avoid melting of the silicone ring sealed at high temperature.
8. Carefully sintering materials containing alkaline ions, alkaline ions will cause crystallization damage to the cavity or.
