【 摘 要 】

In this study, municipal solid waste incinerator (MSWI) ashes were melted by electric-arc technique to produce man-made vitreous fiber (MMVF) using a fiber blowing method. The capacity of 50 kg/h at the pilot level was constructed to treat MSWI ashes and produce MMVF simultaneously. The fibrous derivatives were blended with cement to manufacture fireproof product. The MMVF produced in this work belong to short fiber which the characteristics are presented as follow: (1) fiber diameter range from 5.1 ± 1.2 μm; (2) shot content 6.3±0.8 wt.%; (3) fibrous length ranged from 0.3-3.5 cm. When the amount of MMVF added is at 43 wt.% in fireproof product, the density, porosity, fracture loading and flexural strength are 0.8 g/cm3, 66%, 42 kgf and 98.4 kgf/cm2, respectively. After a series of fireproof test, the fire resistant product had good performance on flammability and incombustibility characteristics. The fireproof product is stable and has satisfactory physical, mechanical and thermal properties.
