説明
In the previous paper, the burning characteristics of grouped polymer cables were studied by using a new test method developed by authors. As the result, it was found that the flame spread rates for grouped PVC cables exhibit a peculiar retardation at a certain range of oxygen concentration in ambient gas flow, in contrast to a single cable (see Fig. 2). <br>The purpose of this study is to make clear experimentally the behavior and mechanism of this retardation. Main part of the experiment consists of the burning test for pre-heated poly-vinyl chloride cables. The effects of pre-heat temperature, flow rate of ambient gas, and cable numbers on the flame spread rate of the grouped cables were observed systematically. <br>Moreover, the concentration of hydrogen chloride in diffusion flame of the grouped cables fixed by a moving wire technique is analyzed, because the HCl released from PVC would act as a flame inhibitor. <br>The results are summarized as follows; <br>(1) Since the retardation of flame spread rate appeared in the burning of grouped PVC cables has never been found for PVC cables pre-heated at above 220°C and chloroprene rubber cables, this behavior is a special character of PVC cable, and perhaps relates to the dehydrochlorination in the first stage of the degradation of PVC. <br>(2) The relative concentration of gaseous hydrogen chloride in flame for the grouped PVC cables shows a maximum value at the same oxygen concentration where the above mentioned behavior appears. It is concluded, thus, that this retardation is concerned with the flame inhibiting effect of HCl.
