| Popis: | 106 This study is for the marine firecut putty through the change of the material-polystyrene foam-shaped ball,by adding polystyrene foam-shaped ball or the removal of polystyrene foam-shaped ball, coating on the test body for combustion penetration test, To compare the fire-prevention ability of polystyrene foaming ball and not adding polystyrene foam-forming sphere, after the two combustion test of the expansion layer scraping off its ashes residue, both take the same weight of the Ashes residue, and then mixed with the weight of the bulk items of soil, the relevant chemical and compliance with government regulations of the Test, The pollution layer of soil is compared with each other. According to the observations after the test and the test results, the fireproof fillers for ships with polystyrene foam balls are not far from the fireproof fillers for ships without polystyrene foam balls. Both are applied. On a three-ply wood board with a length of 20 cm and a width of 9.5 cm, 5-minute burn test was performed using a burner with a discharge temperature of approximately 700°C to 800°C. Both the smeared backs of the plywood were burned out and the sheet spontaneously burned. After the combustion test was completed, the burned ash was immediately scraped off and collected separately into bags. Take 500g soil test body with the same background value as two test pieces and pour it in. After a certain amount of ashes, the content of Dioxin and the content of harmful substances were examined. In combustion test, both of them burned through the board. The test results in Dioxin were different from those expected, and the difference in the concentration of Dioxin between the two was not large. |
