Sorbent based on polyurethane foam with combined effect for fixing pollutants from solid surfaces and water level

摘要

sorbent with combined u00facinkem for fixation zneciu0161tuju00edcu00edch substances from solid surface and water levels based on polyurethane foam.when the pore polyurethane foam is crushed ashes after combustion of biomass combined hydrofobizovanu00fd plant origins.the ash is hydrofobizovu00e1n with organic fatty acids and their derivatives or organosilikonovu00fdch sloucenin.to increase the resistance against rozmeu0161ovu00e1nu00ed already saturated sorbent mechanical pusobenu00edm, possibly pusobenu00edm pressure water, it is possible to pru00edsadu coagulation based on reactive calcium sloucenin,and calcium sulphate or calcium hydroxide or calcium oxide.
