Product Description

�Nice Foundry Sand� serial Foundry material products are high-quality aux foundry materials that can improve quality as well as cut down the energy-consuming and environmental pollution. Its major characteristics are as follows: &#***4;.Major parameter of the Nice Foundry Sand (NFS): 1.Main Chemical element: AL2O3&#***5;*5% Fe2O3&#***4;5% Tio2&#****6;2.5%*3.5% SiO2&#****6;***2% else: tittle. 2.Shape: Ball Shape 3. Shape Coefficient&#****6;&#***4;1.1, very close to ball 4. Density: 1.***2.*5 (g/cm3) 5.Fire-retardant temperature: &#***5;***0&#***1; 6.Heat dilating rate: 0.*3%&#****8;Heated up for *0 Minutes at ***0&#***1;&#****9; &#***5;. Excellence of NFS: 1.Very good shape. Shape Coefficient&#***4;1.1, very close to ball, can decrease by *0% of the usage of felted dosage, strengthen the fluidity, increase the recycling using, cut down the wasting. 2.High Fire-retardant temperature: Fire-retardant temperature &#***5;***0&#***1;, avoiding greatly the adhibiting of the sand, improving the quality of the foundry wares� quality, while decreasing the cleaning works of foundry at the same time. 3.High anti-pressure character and stable volume: NFS need to mould through electronic furnace, and its anti-pressure can reach *0GPa, line dilating Coefficient is 0.**6×***6. It can efficiently guarantee the size of the foundry wares, cut down the disfigurement, and hard to put into powder that help to keep away the pollution.
