中文摘要:
      本研究以实验室自制不同酸度系数的高炉渣棉纤维为基材,分别采用聚乙烯醇缩戊二醛(PVA-GA)和酚醛树脂为粘结剂制备高炉渣棉纤维板,找到最适宜制备纤维板材的高炉渣纤维的酸度系数,以最适宜酸度系数高炉渣纤维制备纤维板,考察两种粘结剂制备的保温板容重,并进行对比研究,用硅烷憎水剂对粘结剂改性后考察其对纤维板容重的影响,最后对其燃烧性能进行了测试。结果表明:酸度系数1.20的高炉渣纤维制备纤维保温板更为理想,聚乙烯醇缩戊二醛作粘结剂的高炉渣棉保温板容重为128.38 kg/m3,改性后粘结剂制作的纤维板容重可达126.60 kg/m3,与酚醛树脂保温板容重123.47 kg/m3比较接近,说明聚乙烯醇缩戊二醛作粘结剂制备保温板在容重方面较为理想,但该保温板不适用于外表面温度300℃及以上设备的保温。
英文摘要:
      In this study, lab-made blast furnace slag wool fiber is used as base material, polyvinylglutaraldehyde (PVA-GA) and phenolic resin are respectively used as binders to prepare blast furnace slag cotton fiber board, the bulk densities of the insulation boards prepared by these two binders are investigated and compared, the binders are modified with silane water repellent and its influences on fiber board densities are investigated, finally the combustion performances of the fiber boards are tested.The results showed that:the density of blast furnace slag cotton insulation board was128.38 kg/m3with the binder of Polyvinyl glutaraldehyde,approaching the density of phenolic resin insulation board with 123.47 kg/m3, which showed that the insulation board prepared by polyvinyl glutaraldehyde as a binder performed well in terms of density,but these boards is not suitable for insulation of equipment with outer surface temperature of 300℃ or above.
