Study of Environmentally Friendly Phosphate-Bonded No-Bake Sand
Regarding dry strength as the index, and considering liftability and storage stability, effects of solidification agent amount and organics N on the property of high neutralization degree phosphate no-bake sand mold/core were studied by modifying the binder coded 32B8M15 and adding solidification agent fused MgO in sand mixing. A new type of compound phosphate binder coded 32B8M15N4 is developed, and results indicate that, at environment condition of below 15 °C and 50% RH, the proper solidification agent amount is 5% when using high neutralization degree binder coded 32B8M15N4 (its addition amount is 3%) to make no-bake sand, its molding sand sample has high dry strength and good storage stability, its compressive strength, σ0, σ1, σ2, σ3, σ4 is 2.33 MPa, 2.27 MPa, 2.01 MPa, 2.03 MPa, 2 MPa separately.
