Exploration of Pressure Capacity of Transparent PVC Containers
In order to meet the needs of researchers to observe the reaction status inside reaction vessels in real time,some reaction vessels use transparent materials.The vertical cylindrical reaction vessel made of transparent PVC material was taken as the research object,and acid leaching reaction was carried out inside.The material was selected as hot pressed extruded transparent grade PVC sheet,and water pressure tests of 0.1MPa,0.2MPa,0.3MPa,and 0.4MPa were carried out according to GB/T 22789.1-2023.The rupture was analyzed.The results show that the maximum pressure bearing capacity of a DN500 container with a wall thickness of 20 mm is 0.3 MPa,and the main failure mode of the container under pressure is a brittle fracture.
