Introduction To The Principle Of China Benchtop Xrd

Posted by tongdaedith on Jan 13, 2020 in News

When an electric current is applied to the filament of an X-ray tube to heat it to an incandescent state, free electrons are emitted from the surface of the filament. At the same time, the high voltage of tens of thousands of volts is applied to the two ends of the X-ray tube (the anode is positive and the cathode is negative), which creates a strong electric field in the Tongda analysis machine tube, which will force the filament surface and its vicinity Of electrons fly out of the cathode and flow to the anode with great acceleration. When they collide with the anode target, the electrons are suddenly prevented from moving and lose their kinetic energy. About 99% of the kinetic energy is converted into thermal energy and about 1%. Into X-rays.
The free electrons flowing from the cathode filament to the anode form a beam of electrons called tube current. The amount of tube current depends on the number of free electrons emitted by the filament. The more electrons flowing from the cathode to the anode, the greater the tube current and the more electrons that hit the anode target per unit time. The more, the greater the intensity of the X-ray. The number of free electrons emitted by the filament depends on the temperature of the filament. The higher the temperature of the filament, the more electrons are emitted. The filament heating is supplied by the filament transformer. The voltage of the filament transformer is changed by controlling and adjusting, that is, the heating current of the filament is changed to achieve the purpose of regulating the tube current.
The X-ray intensity can be changed by adjusting the tube current. As long as the tube voltage is constant, the X-ray wavelength distribution remains constant regardless of the X-ray intensity.
The voltage applied across the anode and cathode of an X-ray tube is called the tube voltage, which can establish a strong electric field and control the kinetic energy of free electrons. The higher the tube voltage, the greater the kinetic energy of the electrons that hit the anode target, the higher the X-ray energy, the shorter its wavelength, and the stronger its ability to penetrate matter.
The tube voltage is supplied by a high-voltage transformer, usually the secondary winding of the high-voltage transformer is connected to the two poles of the X-ray tube; the primary winding is connected to the power source through a voltage regulator (or thyristor voltage regulation). By controlling and adjusting the primary voltage, the secondary voltage is changed to achieve the purpose of regulating the tube voltage.
With the increase of the tube voltage, the speed of electrons flowing to the anode increases, the number of electrons reaching the anode target surface per unit time increases, and the intensity of X-rays produced by China benchtop xrd also increases accordingly. However, the purpose of increasing the tube voltage is mainly to obtain high energy, that is, short-wavelength X-rays, to improve its ability to penetrate matter.

Purchasing Qualified China Benchtop Xrd

Posted by tongdaedith on Jan 6, 2020 in News

Because the Tongda analysis machine is a very professional instrument, not a professional, it is impossible to understand this instrument, so many counterfeiters drilled holes. Some domestic manufacturers use the characteristic that digital X-ray flaw detection can be faked to produce unqualified products.

If you do not have a professional detection tool, the following simple detection methods can help you identify authenticity:

1. When the probe is not connected, adjust the gain to a relatively large value. The waveform on the screen cannot exceed 10% of the screen. If it exceeds, the instrument is unqualified.

2. See if the vertical linearity is qualified or not.

3, there are some indicators need special test blocks. It is recommended that the new instrument be sent to the provincial metrological testing institute for identification, so as not to be fooled.

4, the price is extremely low.

5. Pay attention to the production process and certification documents. Generally, X-rays require professional training.

The consequences of using an unqualified China benchtop xrd are more serious. Since X-ray non-destructive testing is used in quality inspection or safety inspection, if a quality accident occurs or even endangers personal safety, you can save a little money to buy back the unqualified equipment, which will cause you a very unfavorable situation. We condemn those who make fakes. Please raise your level of technological development so as not to harm others. If a major accident really happens, it will also cause you to lose property and put yourself in prison.

Causes Of Tongda Analysis Machine Error

Posted by tongdaedith on Dez 23, 2019 in News

Tongda analysis machine has more factors as to the error caused by thermoluminescence dating. Taking the results of the thermoluminescence dating of the Yuanqinghua plum bottle as an example, some products are considered to be products from the 13th to 14th centuries, while others are only 600 years old. The main reason for such a large error is that the collected samples have been excavated for many years and the environmental conditions before and after the excavation are different. For example, in the past, the tested products were treated by soaking in sewage, cooking at high temperatures, or repairing.

This situation will lead to incorrect thermoluminescence dating of cultural relics. In addition, the level of non-destructive testing technicians will also affect the test results, because non-destructive testing not only requires the operation of the instrument, but also the inspectors need to have cultural relics expertise, cultural level and other literacy. If the conditions in these areas do not meet the standards, the results of the China benchtop xrd test may be affected by human factors.

Introduction To The Composition Of The Tongda Analysis Machine

Posted by tongdaedith on Nov 25, 2019 in News

The Tongda analysis machine consists of four parts: an X-ray generator (X-ray tube), a high voltage generator, a cooling system and a control system. When the parts are independent, the high voltage cable is used to connect the high voltage generator and the ray generator.

According to the structure of an X-ray machine, X-ray machines are generally classified into three types: portable X-ray machines, mobile X-ray machines, and stationary X-ray machines.

Portable X-ray machines use a combined X-ray generator. Its X-ray tube, high voltage generator and cooling system are installed together. It is also referred to simply as a ray generator. The X-ray generator is filled with an insulating medium. The whole machine consists of two parts: controller and ray generator, connected by low voltage cable. The insulating medium of the radiation generator is an early high-resistivity transformer oil. Its resistivity should not be less than 30 ~ 50kV / 2.5mm. Most filled insulating media is sulfur hexafluoride (SF6) to reduce the weight of the radiation generator.

The above is our summary of the use of China benchtop xrd, I believe it will help you when you use this machine in the future. This is also one of Tongdatek’s main products, and there will be more product introductions on other pages in this website.
