Anti-radiation barium sulfate is a good protective material for high-energy ray protection
When barium sulfate is used for interior and exterior wall decoration, it can effectively shield X-rays and Y-rays, and can effectively avoid the leakage of isolation rays. It is mainly used for decoration and application in places where X-ray protection is required, such as dentistry, hospital X-ray room, CT room, etc. Barium sulfate mining and grinding, in line with low-carbon environmental protection requirements. The protective coating generally consists of barium sulfate and cement. After combining according to a certain proportion, it is judged that each 10mm thickness is equivalent to 1mmPb equivalent, and the corresponding thickness meets the protection requirements during construction. The defect of barium sulfate protective coating is simple cracking. How to prevent cracking during construction is the key to the process.
Anti-radiation barium sulfate is a good protective material for high-energy ray protection. It has the advantages of low cost, convenient construction and long service life. Mortar with ray-blocking effect; for barite for ray-proof mortar and concrete, the BaSO4 content should not be less than 80%. Barite is used to make barium cement, barite mortar and barite concrete, and it is used to replace metal lead plates to shield nuclear reactors and to construct buildings for scientific research and hospital X-radiation rooms.
In the planning of the entire construction scheme, the setting of construction joints is the most important part. Before planning the construction scheme, the owners, the relevant persons in charge of the Industrial Sanitation and Radiation Protection Institute, the Planning Institute, the contractor and the supervisor have several meetings to discuss. The problem of setting construction joints. The place where the construction joints are set by the owner and the anti-radiation concern beforehand becomes a weak link. It affects the anti-radiation function of the structure. The barium concrete is poured at one time. We think that whether to install joints or not, the following elements should be considered: if no joints are installed, the construction is quite difficult.
