CeramicFoundry Sand- The Best Replacement for Silica sand,Chromite sand or Zircon sand Main Features 1. High density of the sphericalgrain shapeGrain shape is spherical, a smooth surface and small surfaceareal, very good liquidity and easy to fill. So under goodmold strength and high permeability, comparing with other moldingsand, it could substantially reduce adhesive usage. At the sametime it has the very good collapsibility. 2. Low thermalexpansionThermal expansion rate is lower than other foundry sand. So inthe production, precision of the casting size  quitehigher, less crack and defect, the rate of finished  cast willbe higher a lot. 3. Good resistance to crushingof high density of orb sandAs high intensity, seldom broken even in repeatedregeneration. A substantial increase in sand regeneration backand reduce the waste emissions, conducive to environmentalprotection. 4. High refractorinessMain component is 3 oxidation 2 aluminium, PH value isneutral. It belongs to the department of al-si refractories. Therefractory performance is very good, and it could satisfy therequirement of all kinds of metal and alloy casting. Advantage: 1. Ceramic sand--VS-- Silica Sand1) Refractoriness of Ceramic foundrysand  is higher than silica sand, higher degree of compactingwhen filling model. Therefore, it can make the surface smooth andget good quality of castings, make lower the rejectionrate during production. 

2) Liquidity of sphericalceramic sand  is very good. For complex shaped castings, atangle, deep sunken place, cross hole and any positions which aredifficult to filling , ceramic sand are easy to fill. Thus, sanddefects can significantly reduce the workload of cleaning andfinishing. 

3) Crushing resistance, andhigh recovery rate, thedischarge of wastes is correspondinglyreduced. 

4) Small thermal expansion rate, goodthermalstability, and won't happen expansion to be causeddefects in second phase changement. It improved the precisionof cast much. 

5) In lost foam casting, the dosage of the resin can reduce1/3. 

 

2. Ceramic Sand --VS-- ChromiteSand

1) The packing density is less than the chromite sand, reducethe cost of if use high quality sand. 

2) Less binder used as the spherical granule shape of ceramicsand. 

3) Crushing resistance is good, improve the recoveryrate, better regeneration performance of ceramicsand. 

4) The chromium in chromite sand will cause heavy metalpollution. But there is no environment pollution for ceramic sand.So it is conducive to environmental protection.

 

3. Ceramic Sand --VS-- ZirconSand1) Ceramic sand is spherical, so less binder used thanZircon sand. 2)  zircon sand face the problem of shortage of natureresource. But ceramic sand has rich raw material storage. Soits price less than zircon sand. 3) The high damage resistance and recovery rate of ceramicsand make it in good performance on recycle. Both saved the zirconsand and protect the environment.  Also it avoids theradioactive damage to people from zircon sand. Applications of thesand

- V-methodcasting

- Lost foamcasting

- In the investmentcasting, take replace of zircon sand and zirconsand powder

- In the production oflarge casting, take replace of chromite sand

- In the wet resinbonded sand and clay sand takereplace of silica sand

- Ladledrainage agent, take replace of chromite sand
