In 1895, the German physicist Roentgen studied the gas discharge phenomenon in a cathode ray tube by using a sealed glass tube embedded with two metal electrodes (one called an anode and one called a cathode), and tens of thousands of volts were added to both ends of the electrode. High-voltage electricity, using an air extractor to extract air from the glass tube.

In order to cover the leakage of light (an arc) during high-voltage discharge, a layer of black cardboard is placed on the outside of the glass tube. When he conducted the experiment in a dark room, he stumbled across a distance of two meters from the glass tube, and a piece of cardboard dipped in a solution of platinum cyanide solution emitted bright fluorescence.

Further experiments, using cardboard, wood, clothes and books about two thousand pages thick, can not block this fluorescence. What is even more amazing is that when the fluorescing cardboard is taken by hand, the image of the hand bone is seen on the cardboard.

At that time, Roentgen decided that this was a kind of ray that could not be seen by the human eye but could penetrate the object. Because it cannot explain its principle and its nature is unknown, it uses the "X" representing the unknown in mathematics as the code name, called "X" ray (or X-ray or X-ray for short). This is the origin of X-ray discovery and the origin of the name.

The Chinese desktop xrd uses this feature, using high voltage transformers to apply high voltage to the two metal electrodes to generate radiation. This equipment is used in aerospace, petroleum construction, natural gas pipelines, boilers, pressure vessels and other non-destructive testing equipment.

The penetration capability of Chinese desktop xrd depends on the capacity of Chinese desktop xrd. The tube voltage of Chinese desktop xrd, the higher the tube voltage, the harder the X-ray, the greater the energy, the stronger the penetration ability, the penetration ability and the tube voltage. The square is proportional.

In addition, at the same tube voltage, it is also related to the properties such as the density of the material of the workpiece to be inspected, that is, the ability of the workpiece to be inspected to attenuate the X-rays. For heavy metals such as steel and thicker workpieces, due to their strong ability to attenuate X-rays, Chinese bench xrd with high tube voltage should be selected. For light metals such as aluminum and magnesium, and thinner workpieces, tube voltage can be selected. Lower China benchtop xrd.
