Vacuum atmosphere furnace is a new heat treatment technology combining vacuum technology and heat treatment technology. Then how to choose vacuum pump of vacuum atmosphere furnace? Shanghai Guier's small editor to tell you.
1 atmosphere and vacuum furnace is used to smoke than specific gases in sealed container, the container to obtain a certain vacuum degree of basic equipment, due to the height of the development of modern science and technology, the use of vacuum pump in various scientific fields and various enterprises and institutions, for metallurgy, chemical industry, light industry, petroleum, medical, pharmaceutical, printing and dyeing, electronics, electric vacuum, semiconductor, food, nuclear power, textile and other scientific research institutions, universities and colleges, industrial and mining enterprises for scientific research and production with teaching.
2, due to the vacuum pump is made of black metal, and more accurate, the pump work is associated with oil, so the vacuum atmosphere furnace vacuum pump is not suitable for containing too much oxygen, toxic, with black metal erosion of explosive and effect of vacuum oil gas, also cannot be used as compressor and pump. If there is a gas ballast pump, a certain amount of condensable gas can be removed.
3. The vacuum pump can be used to directly obtain the vacuum operation with the vacuum degree below 10-3 brackets, and cooperate with other vacuum equipment to obtain the vacuum operation with the vacuum degree above 10-3 brackets.
4. The vacuum pump of vacuum atmosphere furnace is generally used in the environment of 50C-400C room temperature and no higher than 90% relative humidity.
Precautions for vacuum atmosphere furnace:
1. Potassium hydroxide (KCN) cannot be mixed with acids because they can produce highly toxic KCN gases.
2. In addition to doing experiments, do not stay in the high-temperature furnace area.
3. Once you find anything that interferes with your safety, please inform the person concerned (technician, etc.) immediately.
4, please save the pure water dosage.
5. After the completion of the experiment, if no one is using it, please turn off the special gas, keep N2 flowing, keep the furnace tube at the standby temperature, and check whether there are other power supplies that should be turned off, such as cleanhood lighting, small electric stove for cooking acid or other, please turn them off.
6. When dealing with HF, please wear gloves. If accidentally touching HF, flush immediately, add 2% water with calcium gluconate, and rub the scratch 15'.
7. The front end of long and short putter, when not in use, please face up to avoid pollution.
8. When the chip enters and enters the furnace mouth, the holder in the boat shall not touch the furnace pipe mouth, so as not to pollute the furnace pipe.
9, quartz glass products, please be careful to avoid breakage, causing serious cuts.
10, avoid inhalation from the furnace or processing tank from all kinds of gas.
11. Do not drop the broken chip, filter paper and cotton stick into the drain hole at the bottom of the cleaning tank to avoid waterlogging due to poor drainage.
