| Description |
The research considers the actual problem of determining the permeability of materials used for the production of personal protective equipment. Having analyzed the methods and instruments for determining the dust permeability and dust capacity of materials, the task is to develop an improved method for determining the dust permeability of materials with high accuracy, based on the use of television measuring instruments. This method is a collection of optical and electronic means by which information about the structure, state and properties of the object contained in its radiation is converted into an electrical signal. On the basis of television measuring instruments, a stand was designed, which made it possible, with a lesser error, to measure the dimensions of the cells of materials used for the production of personal protective equipment. A structural diagram is given and the principle of the stand for determining the dust-tightness of materials is described. New devices have been developed: for fixing materials, which makes it possible to reduce the measurement error and the device for movement of the sample under study. Experimental studies of materials using standard techniques and an improved method have been carried out. The error in measuring the permeability by the improved method has been reduced by 10 %. |
