Abstract

Large amounts of centrifuging waste of mineral wool melt (CMWW) are created during the production of mineral wool. CMWW is technogenic aluminum silicate raw material, formed from the particles of undefibred melt (60-70%) and mineral wool fibers (30-40%). 0.3-0.6% of organic binder with phenol and formaldehyde in its composition exists in this material. Objective of the research is to investigate the possibility to use CMWW as an additive for the production of ceramic products, by neutralising phenol and formaldehyde existing in CMWW. Formation masses were prepared by incorporating 10%, 20% and 30% of CMWW additive and burned at various temperatures. It was identified that the amount of 10-30% of CMWW additive influences the following physical and mechanical properties of the ceramic body: lowers drying and firing shrinkage, density, increases compressive strength and water absorption. Investigations carried out show that CMWW waste can be used for the production of ceramic products of various purposes.

摘要

在矿棉生产过程中会产生大量的矿棉熔融离心废物（CMWW）。CMWW 是一种人造铝硅酸盐原料，由未纤维化的熔融物颗粒（60-70%）和矿棉纤维（30-40%）形成。这种材料中含有 0.3-0.6%的有机粘结剂，其成分中含有苯酚和甲醛。研究的目的是研究将 CMWW 用作生产陶瓷产品的添加剂的可能性，通过中和 CMWW 中存在的苯酚和甲醛。通过添加 10%、20%和 30%的 CMWW 添加剂来制备成型物料，并在不同温度下进行烧制。结果表明，添加 10-30%的 CMWW 添加剂会影响陶瓷体的以下物理和机械性能：降低干燥和烧制收缩率、密度，提高抗压强度和吸水率。研究表明，CMWW 废物可用于生产各种用途的陶瓷产品。
