Investigation of the possibilities to modify the building ceramics by utilising MWCNTs

摘要: Abstract Research deals with the possibility to improve properties of ceramic products by utilising modifying additive multi-walled carbon nanotubes (MWCNTs), mixed carboxymethylcellulose (CMC), which has dispersant, (MWCNTs + CMC). It was found that after insertion (MWCNTs + CMC, sufficient reach 0.0045 mass percent MWCNTs in overall formation mass) into products’ mass, plasticity as well stability increase considerably and microstructure semimanufacture changes. Density strength semimanufactures become higher. Modified structure influences physical mechanical burned bodies, values parameters. However, for case when burning out sawdust is used composition no noticeable influence on body. In this case, absence can be explained considering dry porous surfaces easier more intensively absorb water dispersion particles additive, therefore distribution these limited. Carbon nanotubes, adsorbed locally particles, burn together sawdust. such a way positive blocked. This interpretation confirmed effect other additive–dispersed anthracite, distinguished its hydrophobic properties, introduced mass.
