<p>The invention relates to rural construction sphere, in particular, to building technological elements of cattle-breeding premises. Existing floor design decisions of cattle-breeding premises do not fully correspond (by a number of functional parameters) to zoo hygienic and operational requirements for such constructive elements. It is offered to produce such constructive elements (coverings and floor preparations) of composite materials on mineral filler and thermoplastic binding (polythene) - of dense and open porous structure. Formation of elements takes place at interaction of composite system components in the result of mineral grainy material's preliminary heated surface moistening by polymer fusion. Polymer particles, contacting (in a mixer) with the surface of the material grains that are heated up to their fusion temperature, get warmed, fuse and adhere to the grain surface. Spreading and polymer film forming on each grain of the material during mixing of the components takes place. Then the mass is taken out of the mixer and a filtering element is formed at pressure up to 1.0 - 5.0 MPa, and it hardens at its cooling, that defines readiness of the product for application.</p> |
