Background of handheld XRF analyzers

XRF (X-ray fluorescence) is an innovative, non-destructive technology for material analysis. It`s unique and almost universal,
An X-ray gun sees sample contents by using an X-ray source to measure the secondary ways (fluorescent) the sample emits. Such an analysis is clear and fast.

Portable XRF Spectrometers can be used in any field that requires analysis of elements or compounds from Na to U. The main business industries include building materials (cement, glass, ceramics), metallurgy (steel, non-ferrous metals), petroleum (trace elements such as S, Pb, etc.), chemical industry, environmental protection, food safety, geological mining, commodity inspection, quality inspection, and human body trace element inspection, etc.

handheld XRF metal tester Working principle

The sample is bombarded with X-rays, and the sample is excited to produce X-ray fluorescence.

X-rays usually knock out the inner electrons of the K and L layers of the element atoms, and the generated holes are filled by the high-energy outer electrons. High-energy electrons replenished to low-energy orbits radiate the excess energy as X-ray fluorescence.

These radiated spectral lines contain the characteristics of various elements. Like a fingerprint, and independent of the chemical valence states of the atoms. The intensity of the radiation is proportional to the concentration of this element in the sample.

[wire drawing machine]

The wire drawing machine usually changes the diameter or shape of the wire from the disk to the disk through the wire drawing die to move the required diameter or shape. The wire must be lubricated when it enters the drawing die, and the drawing die has a dedicated cooling (usually water-cooled jacket cooling). The closing machine provides power.

The wire enters the drawing chamber through the pay off frame and is stretched through the tower wheel and drawing die. The cooling method of wire rod drawing is spraying and half soaking. Then it passes through the constant speed wheel and then the traction wheel to enter the take-up reel. The stretching tower wheel is arranged horizontally in a single row.

The wire drawing machine body is welded with steel plate and section steel. The tower wheel shaft transmission adopts double chain transmission. The tower wheel surface adopts special treatment to improve the surface hardness and roughness. The die base adopts inlaid design to ensure the center distance of drawing and reduce the probability of wire breaking. The upper part of the drawing box is equipped with hinged start-up closed protection box cover to prevent the coolant from splashing out.

The cooling circulating water tank has electric heating function to meet the requirements of wire drawing process, and the wire breaking and stopping device is set at the inlet
