Muffle furnace reducing flame, intelligent muffle furnace where is there a smart muffle furnace smar

I think it's to close the chimney and reduce the oxygen.

The reducing flame refers to the flame in the combustion process, the oxygen is insufficient, the combustion is insufficient, and there is no or very little free oxygen in the combustion product of reducing gases such as carbon monoxide.

Also known as:"Restore the atmosphere"That is, when the kiln is fired, the ventilation in the kiln is poor, there is a lack of oxygen, and the glaze containing copper will appear red in the reducing flame.

Because the reducing flame can fully reduce the ** iron (Fe2O3) in the body to ferrous oxide (FeO), and turn into cyan, eliminating the phenomenon of porcelain yellowing, so in the process of firing daily porcelain, the reducing flame is mostly used. The kilns in the southern porcelain areas of China are generally fired by reducing flames.

The composition of the flame determines the redox characteristics of the flame, and directly affects the decomposition of the element compounds to be measured and the formation of refractory compounds, which in turn affects the atomization efficiency and the effective lifetime of the free atom flame region. There are many factors that affect the composition of the flame, such as the type of flame, the fuel-assist ratio of the same type of flame, the combustion environment of the flame, etc. For the same type of flame, according to the change of the combustion aid ratio, it can be divided into rich flame, stoichiometric flame and poor flame.

The so-called stoichiometric flame means that the combustion assist ratio is completely in line with the combustion reaction coefficient ratio of the gas and the auxiliary gas. This flame has the highest temperature, but the flame itself does not have redox properties. Although the flame temperature is slightly lower than that of the stoichiometric flame, the concentration of carbon atoms in the flame increases due to the increase of gas, so that the flame has a certain reducibility, which is conducive to the generation of ground state atoms.

In a closed muffle furnace, some carbon or graphite powder is placed or gas is introduced.

The principle of ceramic fiber muffle furnace in this paragraph.

The ceramic fiber muffle furnace has completely changed the shortcomings of the domestic muffle furnace, such as bulky and heavy, easy damage to the electric furnace wire, and slow heating speed, and its performance has reached the level of similar imported products. The ceramic fiber muffle furnace body is made of American ceramic fiber material, which has good thermal insulation performance (the surface temperature of the furnace body is only 60 when it rises to 1000, and the national standard is about 100) and is light in weight. The ceramic fiber muffle furnace heating wire is made of the world's top alloy materials.

The heating temperature of the ceramic fiber muffle furnace is uniform, the heating speed is fast, it only takes 12 minutes to rise to 1000 (very suitable for the chemical industry), the traditional muffle furnace takes about 80 minutes, the energy saving performance is good, the BA-3-10B ceramic fiber muffle furnace is about 40% of the energy consumption of the ordinary muffle furnace, and the dust and slag will not affect the effect of the test.

Application of ceramic fiber muffle furnace in this paragraph:

I've learned about this. Zhengzhou Jintai Technology is very good, and their products are also very advanced, all of which are fully automatic with microcomputers. The service is also good, as well as ** return visit, free maintenance service.

Buy a large instrument to make it easy to use, good after-sales. You can call 0371-53777436 to check.

Upstairs is right. The service is really good, and the return visit is also **.

The domestic insulation cotton is thicker than the imported muffle furnace, but the insulation effect is not as good as the imported muffle furnace. When you touch the domestic one, it's very hot, but the imported one doesn't feel it.

The difference is too great.

The temperature zone and control of domestic products are not of the same order of magnitude.

The design concept and the materials used are also completely different, which is also the reason for the difference of more than 10 times.

The difference is that the origin is different, and the raw material estimation is also different.

The same, except that the domestic ones are marked "made in China" on them

The special muffle furnace for sewage treatment is specially used for sewage treatment plant to treat sewage, organic soil drying, volatilization, and testing. The furnace is made of high alumina liner, which has good wear resistance, and the furnace is heated on all sides. The shell is sprayed with cold plate, and the appearance is beautiful.

It has the characteristics of high control accuracy, fast heating speed, programmable temperature control, etc. The standard name is "Programmable High Temperature Furnace", model: SXF-4-10.

There is no difference, all of them are used for high-temperature calcined samples.

The specific measurement method can be checked in the national standard or the corresponding industrial analytical chemistry book.

At present, the muffle furnace is mainly heated by electric furnace wire and silicon-molybdenum rod. The latter can be heated up to 1600 degrees. It's basically the same way to use it. If you have smart temperature control, you need to study the manual to set up the heating program. But no matter what kind of muffle furnace there are a few points that must be followed:

1. After turning on the machine, control the small current and slowly warm it up for 3-5 minutes.

2. Set the maximum temperature and alarm temperature of burning.

3. Do not open the furnace lid when the temperature exceeds 600 degrees.

4. Select the appropriate crucible according to the sample and the maximum temperature.

5. After the burning is completed, wait for the natural cooling to 400-500 degrees, and transfer the crucible to the dryer to cool to room temperature. After weighing.

Thinking about this for the time being, it should be more practical. Read more of the manual!

Looking at the manual, different muffle furnace parameters and control panels are different, in fact, the current manual must be very detailed.

Ash: weigh the sample in a square crucible, put it in a muffle furnace, bake it at 800 for 1 hour (put it when there is no temperature, and then time it when it rises to 800), take it out and put it in a dryer to cool, weigh, calculate:

Ash % = (weight after baking - crucible weight).

Volatile matter: weigh the sample in a crucible with a lid, put it in the lid when the temperature of the muffle furnace rises to 900, bake it accurately for 7min, take it out and put it in the dryer to cool, weigh, calculate:

Volatile matter % = (crucible weight - weight after baking) Internal water: weigh the sample in a crucible with a lid, bake it in an oven (temperature 120-150) for hours, take it out and put it in a dryer to cool, weigh, calculate:

Inner Water % = (Crucible Weight - Baking Weight).

This ** will have what you want.

1600 degrees of high temperature muffle furnace, Hangzhou Lantian Laboratory Instrument Factory produced quite a lot, there are box type and tube type, tube type and with corundum tube and stainless steel flange seal, its heating material is silicon molybdenum rod. It is best to communicate with the manufacturer before using this kind of furnace, and whether it is necessary to bake the furnace first, because the manufacturer's debugging is usually not directly debugged at 1600 degrees when the furnace leaves the factory.
