Abstract

ία μέθοδος κατασκευής μιας συνθέσεως ήτις περιλαμβάνει εν υλικόν υπό την μορφήν τεμαχιδίων συνδεδεμένων ομού δια τινος ακάμπτου σπόγγου εκ πολυουρεθάνης, η δε μέθοδος αύτη περιλαμβάνει την ανάμιξιν των συστατικών δια τον εκ πολυουρεθάνης σπόγγον μετ' αλλήλων, την πρόκλησιν ή άφεσιν του λαμβανομένουμίγματος να διασταλή εν μέρει, και μετά ταύτα τηνπροσαγωγήν του εν μέρει διασταλέντος μίγματος ειςεπαφήν μετά του υπό την μορφήν τεμαχιδίων υλικού και την πρόκλησιν ή άφεσιν της μεθόδου σπογγοποιήσεως να χωρήση μέχρι πέρατος προς παραγωγήν μιας κατ' ουσίαν ομοιογενούς συνθέσεως ήτις περιλαμβάνει το υπό την μορφήν τεμαχιδίων υλικόν και ένα άκαμπτον σπόγγον εκ πολυουρεθάνης. A method of making a composition comprising a material in the form of particles bonded together for a rigid polyurethane sponge, and this method comprises mixing the components of the polyurethane sponge with one another, causing it to leave or leaving it , and thereafter bringing the partially expanded mixture into contact with the particulate material and causing or allowing the sponging process to be complete to produce a substantially homogeneous composition or comprising the solid material in the form of a particle. of polyurethane.
