Sodium Sulfate → Sodium sulfate decahydrate

Participants

Reaction Steps

The present invention also discloses a method of making the composition. The method consisting of the steps: (1) Preparing an aqueous solution of compound of copolymers at a concentration of 1% to 2% by weight. (2) Mixing solid, powdered sodium sulfate, fusion temperature-depressing salt, borax and water to form a paste mixture A. (3) Mixing the aqueous solution of compound of copolymers with the paste mixture A to form a mixture B. (4) At a temperature of 28-35° C., mixing the mixture B with a kind of fibres to form the composition. Eutectics of sodium sulfate decahydrate (Na2SO4.10H2O) and the fusion (melting) temperature-depressing salt are formed in the composition.
