The enamel element was discovered by Cliff in Sweden in 1879 and was named Thulium in the old name of Scandinavia. î´ the expansion tank is at the highest point in the cooling system and requires plenty more plumbing than the overflow tank,but this system is more efficient for relieving high pressures from heated coolant since it's always being fed into the tank to expand.because the expansion tank uses a pressurized cap and relief nozzle,you can still run an overflow tank in line to keep any drops of coolant off the track European truck Expansion tank ,Scania expansion tank,Iveco Expansion tank SHANGQIU FLAT WORLD MACHINERY CO.,LTD , https://www.flatworldtrucks.com
The main uses of bismuth are as follows: (1) é“¥ is used as a medical portable X-ray machine source, and an X-ray isotope is generated after irradiation in a nuclear reactor, which can be used to manufacture a portable blood irradiator. This type of radiometer can convert é“¥-169 into a é“¥-170 by the action of a high neutron beam, emitting X-rays to illuminate the blood and lowering white blood cells, and it is these white blood cells that cause organ transplant rejection, thereby reducing organs. Early rejection. (2) The strontium element can also be used for clinical diagnosis and treatment of tumors because it has a higher affinity for tumor tissues, and heavy rare earths have greater affinity than light rare earths, especially with the highest affinity of strontium elements. (3) The activator LaOBr:Br (blue) is used as an activator in the phosphor for X-ray intensifying screen to enhance the optical sensitivity, thus reducing the X-ray exposure and harm to humans, and the previous calcium tungstate intensifying screen. This can reduce the X-ray dose by 50%, which has important practical significance in medical applications. (4) can be done thulium novel additive metal halogen illumination source. (5) Tm3+ can be made into rare earth glass laser material by adding it to glass. This is the solid laser material with the largest output pulse and the highest output power. Tm3+ can also be used as an activated ion for rare earth upconversion laser materials.
