The Applications of Industrial Instrument Explore Tungsten Radiation Protection

Due to its high density, excellent absorption behaviour against radiation and environmental friendly characteristics, tungsten alloy can be widely used in industrial instrument explore tungsten radiation protection. Industrial instrument explore tungsten radiation protection can be used in welding inspection, container inspection, and oil and gas logging.

Manufacture Processes of Industrial Instrument Explore Tungsten Radiation Protection

The main manufacturing techniques of industrial instrument explore tungsten radiation protection can be divided into four process, mixing, pressing, sintering, and machining.

The process comprised the mixing of a tungsten alloy powder (such as: with content of 92.5 et.% W and the balance of Ni, Fe) with an organic binder, thermoplastic shaping of mixture to a green sheet material by an extrusion process, followed by de-binding and sintering. The sintering step was performed in hydrogen atmosphere under liquid phase sintering conditions at a temperature range of 1450°C to 1500°C. Depend on the different needs of customers, tungsten radiation shielding can be produced into different thickness and sizes through machining including milling, punching, drilling, polishing and threading.

The Advantages of Industrial Instrument Explore Tungsten Radiation Protection

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy radiation bricks provide excellent density with small capacity. At the same tungsten alloy radiation brick with weights high density alloy can provide the same energy absorption as lead using 1/3 less material.

During design of shielding, tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
Formula: K=e0.693 d / △1/2
K: Shield weakened multiple
△ 1/2: The tungsten alloy radiation shielding material of the half-value layer values
