What is ceramic spraying?

        Just like Deng Ziqi's "period", the arrival of the traditional Chinese festival - the Spring Festival has entered the countdown, and 2020 is also the beginning of 2021. Looking back on 2020, the most unexpected takeaway for me is that the company's powder material has entered the supply sequence for another national project. Although the entire company is Buddhist, we are working fully with clients who actively invest in Olive Branch. After 8 months of working with our customers, our powder-prepared coatings have been accepted.



 

The taste of wine is also afraid of deep alleys. Based on the principle of not revealing customer secrets, the application of ceramic spraying in the field of nuclear power is briefly introduced.

On March 11, 2011, a massive earthquake measuring 9.0 on the Richter scale struck Japan, followed by a tsunami that hit the Fukushima Daiichi nuclear power plant. Finally, the accident level of the Fukushima nuclear power plant was set to the highest level of 7, and the first one equivalent to the Fukushima accident was the Chernobyl accident in the former Soviet Union. Japanese authorities have acknowledged that molten nuclear reactors have begun to pollute downwards and have begun polluting groundwater. Rescue efforts at the Fukushima nuclear power plant have relied heavily on cooling water, a passive, symptomatic approach. It can be seen that although the Fukushima nuclear power plant accident was caused by a natural disaster, the continued deterioration of the accident was caused by the delay of the Japanese authorities. In 2020, the Japanese government decided to accept the proposal of the Japanese expert group to discharge the tri-containing sewage from the Fukushima nuclear power plant into the Pacific Ocean as a neighbor of Japan. South Korea has been banning seafood imports from Japan's Fukushima region after the nuclear accident. Many anti-nuclear activists in Japan also oppose the discharge of this waste water into the ocean. They argue that even though tri is weaker than strontium and cesium, it should be removed. The Japan Fisheries Organization has repeatedly expressed concern about the practice, arguing that it would destroy local fisheries. On March 26, the relevant person in charge of China's Ministry of Environmental Protection (NNSA) introduced that the environmental protection department detected extreme conditions of aerosol samples at three monitoring points in Raohe County, Fuyuan County and Hulin County in Heilongjiang Province. . Traces of the artificial radionuclide iodine-131.

Systems that store and discharge cooling water often require treatment with a tri-barrier layer, but as an isotope of hydrogen, it is highly resistant to corrosion.



 



The systems that store and discharge cooling water usually need to be treated with a tritium-blocking coating, but as an isotope of hydrogen, tritium has a strong reducibility, and it is easier to dissolve and penetrate in metal containers at high temperatures, bringing health benefits to workers. to threaten. Ceramic materials have very low hydrogen solubility, diffusivity and permeability, and are excellent tritium barrier materials, but due to their inherent brittleness, it is difficult to process into hydrogen storage and tritium containers. Therefore, we can use surface coating technology to prepare a suitable ceramic coating on the stainless steel surface to achieve the effect of preventing tritium penetration.
