Garnet filter material
The garnet filter material is also called the jade sand or natural diamond sand, and it has good hardness and fine properties of acid and alkaline endurance, and it is a kind of island-shape aluminosilicate. It is colorful and beautiful and it shows many colors such as grey, red, green and white after the magnetic separation with high purity. It is the cubic paints developed by the foreign countries recently, and it is the grinding-enduring material used by the glass plant in manufacturing the sand blast of colorful shells. Because it has many internal chemical molecules, it has the features such as high chemical stability.
Garnet is a kind of island-shape aluminosilicate and it is one of the natural mineral of grinding materials. According to different ingredients, it can be divided into many kinds such as iron-aluminum, calcium-aluminum, calcium-iron and manganese-aluminum garnets. This kind of mineral is seldom produced in single type, and most of them are the mixing type, and among with the iron-aluminum garnet has the maximum hardness.
The ingredient of iron-aluminum garnet is Fe3Al2[SiO4]3 and it is also called the almandine; the crystal often has the shape of dodecahedron. It is red, dark red or brownish red, the hardness is 7.5-8 and the gravity is 4.0-4.2.
Because of large hardness (the Moh’s hardness is 7.5-8) and good crystal shape, it has sharp angles after being shattered, and it is specially applicable for the natural grinding material and the material for sand spraying and polishing. It is mainly used in the polishing of the metal in plane, ship and automobile manufacture, the polishing of the furniture with high quality, the polishing of kinescope, ceramics and glass, the polishing of feather and rubber. It can also be used in the working sequences of aluminum profiles. As the natural diamond sand, its annual productivity and consumption amount in the international market has been increasing.
The garnet has high intensity, strong capability of anti-grinding; it doesn’t contain dissociative silicon dioxide, and has high density; it doesn’t contain organic matters and can be used as the filtering materials of sand layers – where the anthracite is on the top, the quartz sand is in the middle and the garnet is at the bottom. It is used in the industrial filtering system and swimming pool, and can have the effect of eliminating pollution and purifying the water.
