RESEARCH OF TECHNOLOGICAL AND OPERATIONAL PROPERTIES OF ENERGY- EFFICIENT HEAT INSULATION MATERIAL ON THE EELGRASS BASIS
Abstract
Insulation material gained on the basis of local raw materials is considered in a paper. Sea grass has been used as a filler in the experimental compositions. In our experimental studies we have used organic (PVA emulsion and cellulose) and inorganic (liquid glass, cement, lime) substances in order to choose the best type of binder.It was found that sea grass has a low bulk density and fibrous structure, a large mechanical strength, resistance, and also does not rot, burn, and can not be damaged by microorganisms and rodents.
Also eelgrass maintains its physical and mechanical properties for millennia. A comparison of the samples on different types of binder is done. The dependences of density samples and compressive strength at 10% deformation content of binder are established. To be able to compare with other heaters the basic physical and mechanical properties have been defied: bulk density – 200-600 kg / m3, thermal conductivity coefficient – 0,049-0,087 W / m ∙ K, ultimate tensile strength in compression – 0,246-0,294 MPa, ultimate tensile strength in bending – 0,21-2,24MPa, border tensile strength – 0,025-0,056 MPa.
The resulting material is environmentally friendly, has high heat insulation properties. Production of heat insulation plates of such material will make the first steps in resolving the energy crisis in Ukraine and in the whole world and can allow recycle hundreds of thousands tons of sea grass. This material will compete with existing insulation materials.
Keywords: energy efficient insulation material, sea grass, liquid glass, thermal conductivity coefficient, fire resistance.
