| titleOfInvention | A kind of hemihydrate-anhydrous calcium sulfate mixture with stable structure and preparation method thereof |
| abstract | A structurally stable hemihydrate-anhydrous calcium sulfate mixture and a preparation method thereof, wherein the structurally stable hemihydrate-anhydrous calcium sulfate mixture can naturally Storage, the crystal morphology and crystal form remain stable within 180 days; natural storage in an environment with a temperature of -40°C to 40°C and a relative humidity of 40% to 60%, the crystal morphology and crystal form remain stable within 15 to 60 days Stable; naturally stored in an environment with a temperature of ‑40°C to 40°C and a relative humidity of 60% to 100%, the crystal morphology and crystal form will remain stable within 5 to 32 days; placed in water at 0‑40°C, hydrated The time was extended to 80min. In the present invention, by finely controlling the heating temperature, α-CaSO 4 ·0.5H 2 O can remove part of the crystallization water in the structure to obtain soluble type III α-CaSO 4 and α-CaSO 4 ·0.5H with controllable crystal form and structure 2 O mixture, and still maintain the original crystal morphology. |
