Method for evaluating protective performance EBT value of modacrylic arc-proof fabric

Abstract

The invention discloses a method for evaluating the protection performance EBT value of an arc proof fabric with modacrylic as a main component. The method comprises the following steps: constructingan evaluation index system of the EBT value of the protective performance of the modacrylic arc-proof fabric; selecting different modacrylic arc-proof fabrics; testing performance parameters of related influence factors of the fabric according to the evaluation index system; testing the EBT value of the fabric; using SPSS correlation analysis to determine main influence factors; establishing a multiple regression equation of the EBT value and the main influence factor; and verifying the multiple regression equation; the invention has the following beneficial effects: a new method for effectively evaluating the EBT value of the modacrylic arc-proof fabric is provided; according to the method for evaluating the protection performance EBT value by utilizing the basic performance of the fabric, existing equipment in a laboratory is reasonably utilized, new equipment does not need to be developed additionally, so that the problems of high direct evaluation cost, long test period and the like of the protection performance of the arc-proof fabric are solved; the indirect evaluation method is simple and clear, is convenient to operate, and can be used for directly and quickly judging the EBT value of the modacrylic arc-proof fabric.

Description

technical field [0001] The invention relates to the technical field of an evaluation method for the EBT value of the protective performance of an acrylic anti-arc fabric, in particular to an evaluation method for the EBT value of the protective performance of an acrylic anti-arc fabric. Background technique [0002] Arc is a gas discharge phenomenon that presents arc-shaped white light and generates high temperature. The huge heat released by the arc can directly burn the skin or ignite clothing. At the same time, the high temperature will cause the explosive expansion of gas and metal in the environment, and its speed is enough to penetrate into the human body. The human body does great harm. In the daily work of electric workers, except for arc welding, electric arc furnace and other heat sources, most arc phenomena are harmful to personal safety and equipment safety. At present, there are two standards for judging the arc protection level, namely arc thermal protection p...

Problems solved by technology

However, there are no professional testing standards and testing institutions in China, and it is impossible to quickly and accurately know the protective performance of arc-proof fabrics.

In order to solve the problems of high cost of direct evaluation of the arc protection performance of arc protection clothing and long test period, it is necessary to explore the influence of the basic physical properties of the fabric on its protective performance from a mathematical point of view, and to establish a nitrile The evaluation method of the EBT value of the anti-arc fabric of chlorinated fiber, the scientific evaluation of the EBT value of the anti-arc fabric with acrylic chloride as the main component, provides a reference for the development of anti-arc clothing in my country's electric power industry. Therefore, an improved technology is urgently needed To solve this problem existing in the prior art
