Method for manufacturing a temperature detecting wire
Abstract
Abstract A METHOD FOR MANUFACTURING A TEMPERTURE DETECTING WIRE WHICH COMPRISES THE STEPS OF HEATING A MIXTURE OF VANADUIM PENTOXIDE AND DIAMMONIUM HYDROGENPHOSPHATE TO A TEMPERATURE OF 500* TO 550*C. IN AN ATMOSPHERE OF NITROGEN GAS, REDUCING MOST OF THE VANADIUM PENTOXIDE TO VANADIUM DIOXIDE BY HYDROGEN EVOLVED THROUGH THERMAL DECOMPOSITION OF THE DIAMMONIUM HYDROGENPHOSPHATE, ALLOWING A REACTION MIXTURE TO COOL IN AN ATMOSPHERE OF NITROGEN GAS, AND THEN HEATING IT AGAIN TO A TEMPERATURE OF 1100* TO 1200*C. TO COMPLETE THE REACTION OF REDUCTION, QUENCHING THE RESULTANT PRODUCT TO FORM A LUMP OF FINE CRYSTALS OF VANADIUM DIOXIDE, GRINDING SAID LUMPS OF FINE CRYSTALS OF VANADIUM DIOXIDE INTO POWERS OF A THERMOSENSITIVE MATERIAL, ADDING TO SAID POWDERS A BINDER MAINLY CONSISTING OF SYNTHETIC RESIN, AND INSERTING A THERMOSENSITIVE LAYER CONSISTING OF A MIXTURE OF SAID POWDERS AND BINDER INTO THE INTERSPACES BETWEEN A PLURALITY OF CONDUCTIVE WIRES.
