Tungsten Multi leaf Collimator

 

Radiotherapy destroys cancer by directing beams of radiation directly onto the tumour. The beams of radiation require a very fine focus to avoid harming the surrounding healthy tissue. This focus is achieved by using a multi-leaf collimator , consisting of two rows of very thin tungsten alloy plates, which can be configured to exactly match the dimensions of the tumour.

Positron Emission Tomography (PET)

 

Positron emission tomography (PET) is one of the nuclear medicine techniques available for diagnosis. Whilst X-rays provide information on the structure of the body, PET shows the chemical function of a particular organism. PET involves the injection of FDG (a glucose-based radionuclide) from a shielded syringe into the patient. As the FDG travels through the patient’s body it emits gamma radiation which is detected by a gamma camera, from which the chemical activity within cells and organs can be seen. Any abnormal chemical activity may be a sign that tumours are present.
PET scans are frequently used to detect cancerous tumours and diseases of the brain and coronary arteries.
Applications for tungsten alloy shielding in PET include:
 
PET syringe shield
Tungsten vial shield
Tungsten FDG transport container
Collimator for gamma camera
Technetium generator

Tungsten Alloy Fake Gold Bar

Detecting a high-quality tungsten alloy fake gold bar would be extremely difficult. It would likely require significant and material alterations to the bar being tested and this would negatively affect the marketability if its hallmark veracity were vindicated. Some applications require the tungsten to be fake gold. The main reasons for tungsten fake gold bar are to protect the wire from corrosion or to solder it to other metals.

Besides,tungsten alloy products could also made as tungsten alloy fake gold bar which posses a better electric conductivity, and contribute greatly to the world industry development. Also tungsten fake gold saves the energy and poses no pollution threat to the environment and thus to achieve a sustainable development.ngsten alloy products could also made as tungsten alloy fake gold bar which posses a better electric conductivity, and contribute greatly to the world industry development.

Tungsten Nuclear Medical Radiation Shielding

 

Tungsten alloy(heavy alloy) is ideal for shielding against X rays and gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics.
 
Tungsten heavy alloy shielding is used in applications such as collimator, nuclear shielding, beamstop, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.

How to Set Rivets

Rivets are used in a variety of home repair, hobby, and craft applications to fasten thin materials together permanently. A rivet forms a connection when the shaft end of the rivet is deformed to hold it in place. Some rivets can be set by hand, while others require a rivet gun. While setting rivets by hand is a fairly easy operation, it's necessary to gather the right tools and safety equipment to do the job right.

1.Prepare the materials to be fastened by drilling a hole through all layers using the drill and drill bit or by using a punch, depending on the material. Steel or aluminum will require a drill bit, while fabrics and leathers will require a punch. Choose a drill bit or punch size that is the same diameter as the rivet shaft. Choose a rivet depth that matches the total thickness of the materials to be fastened. If the rivet is too long, it will not compress enough and the materials will be free to move. If the rivet is too short, it will not grasp the materials enough and it could pull out of the assembly.

2. Insert the rivet through the drilled or punched holes so that the shaft passes through all of the layers.

3. Place the assembly down on the rivet setting pad, with the end of the shaft oriented upwards. The tip of the rivet should be centered on the cone of the setting pad, so that the sides of the shaft can flare out when the rivet is struck.

4. While wearing safety glasses, hit the head of the rivet squarely with the hammer. 5. Turn the assembly over and examine the end of the rivet. The edges should have flared out away from the center, and the material should be fully compressed between the end of the rivet and the head. Repeat Step 4 if the rivet is not fully compressed.
