FABRICATION AND DISMANTLING OF COLLAPSIBLE ASSEMBLY

摘要

FIELD: transport.SUBSTANCE: invention relates to safe transportation of contaminants and pollutants to disposal or processing area. This method comprises bonding of separate elements with the help of hardenable composition based on binder and powder filler. Prior to making hardenable polymer composition of the basis of the mix of polyesters and polyisocyanate component and powder filler as polystyrene pellets components of this composition is selected by feeding its batch through the system of communicated channel of variable-section decreasing in feed direction. This allows determining of permeating capacity and selection of composition with said capacity corresponding to channel diameter wherein displacement of hardenable composition terminates. Composition of selected composition is fed into gaps between separated elements of the assembly to fix and to harden it. Check tests are conducted to dismantle the assembly using organic solvent, for example, acetone.EFFECT: simplified dismantling, higher elasticity and strength.4 cl, 3 dwg, 1 tbl, 11 ex
