Counterweight iron sand. The counterweight iron is a kind of iron ore raw materials in weight, its role is to balance. For example, the counterweight engineering machinery in sporting goods in weight. For weight or pressure reuse of iron ore, iron ore, the proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, customers are in terms of the drainage density (true specific gravity drainage density [1]). The product weight different needs of different proportion of the iron weight. Counterweight iron sand density The proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, specifications: 0.2-2.0mm, customers often to drainage density (specific gravity), as the purchase of indicators. The product weight different needs of different proportion of the iron weight. A small proportion of iron weight: 6.2-6.5 tons / m3 4.1-4.3 tons / m3 reactor A large proportion of iron weight: 6.8-7.2 tons / m3 4.8-5.2 tons / m3 reactor Physical and chemical index Chemical composition Content Iron (fe) More than 93% Carbon (c) Less than or equal to 0.50% Manganese (mn) Less than or equal to 1.20% Silicon (si) Less than or equal to 0.20% Sulfur (s) Less than or equal to 0.25% Phosphorus (p) Less than or equal to 0.05% Counterweight iron sand use 1, sports and fitness activities counterweight 2, electric counterweight counterweight 3, concrete weight 4, the hull large mechanical engineering mechanical pressure 5, wear-resistant engineering, such as the airport runway, bridge pavement, pier, bridge, steel plant, etc..
Pearly sand Perlite is a by acidic volcanic glassy lava through the broken, preheating, roasting and swelling and are made with porous structure, white, loose granular materials, which has the characteristics of small volume, low thermal conductivity, good chemical stability, non flammable, non-toxic, tasteless, sound-absorbing. Pearly sand properties 1. Perlite is a adsorption ability is very strong material, it has good infiltration, infiltration of the pearlite sand surface is wet after the release of heat. 2 pearl sand is a small capacity, low thermal conductivity, good chemical stability of the material. 3 perlite or not flammable, non-toxic and tasteless, sound-absorbing material, has good effect in the industry. Physical and chemical index Component Sio2 Al2o3 Fe2o3 Cao Mgo K2o Na2o Content Seventy-five point four two Fourteen point two six One point zero one One point seven two Zero point three seven Four point zero one Three point two six Pearly sand classification One is the use of perlite building, the particles are relatively large, the intensity is relatively large. The other is the use of equipment insulation, mainly used to make filler, smaller particles, small strength, good thermal insulation. Use of perlite This product is mainly used for large ultra low temperature thermal engineering construction of the insulating layer, such as oxygen air separation unit, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport such as travel. This product has good ultra low temperature thermal insulation performance. The 1 is the perlite insulation materials, can be used to make some use of the roof insulation layer. Heat insulation effect is good, and some can also be used to make the use of crop cultivation soil configuration. 2 production of heat insulation brick used in the construction industry, etc.. 3 making hand washing powder, washing powder of pearlite is other material cannot replace, structure and its screening is very strict.
Ceramsite sand 1, product introduction Ceramsite is a kind of refractory particle with diameter of 0.020mm~2.00mm, mainly made of al2o3·sio2. It is ball-shaped particle made from fine bauxite , which is fused in high-temperature electric-arc furnace and sprayed to ball shape. 2, features of ceramsite 1.Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level 2.Smooth surface of spherical shape greatly improves collapsibility after pouring 3.Low gas evolution and high permeability ensures fewer or no defects 4.High refractoriness and little thermal expansion ensures no burn-on and deformation 5.Artificial sand ensures stable chemical and physical properties 6.Almost neutral ph value allows both acid and basic binder. 7.High durability ensures high reusability. 3, physical and chemical properties of ceramsite ItemIndexItemIndex(%) Bulk density(g/ cm³)1.79-1.95Al2o3>75% Apparent porosity(%)1800Mgo0.23-0.7 Refractoriness under Load (°c)1720Cao0.16-1.5 Thermal expansion rate%(10 minutes under 1000 °c))0.13Tio21.99-2.71 4, applications of ceramsite 1. Used in all types of foundry technique like resin-bonded sand, sodium silicate sand, and clay-bonded sand. 2. As core sand for making like jacket core, oil duct core and tappet core of engine. 3. Excellent replacement of chromite sand 4. As dry sand of sand box for epc process and v method of casting process.
