We Hebei Daguangming Ind.Group is the diversified company, Cenosphere is one of our main products,the total production is 10000Mts per year,We got ISO:9001:2008 Qualityf Certificate,OHAS14001:2008 Certificate.Our Products are exported to USA,Middle-East widely and used in oil-well with heat resistance and other features.
It is also called flying ash hollow ball, grayish white, thin wall and hollow, very light weight, bulk density of 720kg/m3 (heavy), 418.8kg/m3 (light), diameter of about 0.1 mm, closed and smooth surface, small thermal conductivity, refractory degree is less than 1610 DEG C, insulation refractories excellent,.
It is widely used in lightweight castable production and oil drilling.
The chemical composition of cenosphere silica and three to two aluminum oxide based,
It has fine grain, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation, flame retardant insulation and other properties, is widely used in one of the refractory raw material industry.
High melting point (1200 - 1400 ºC) - an excellent choice for use in high temperature insulating refractories, fire resistant coatings and panels
Free flowing - easily pumped in dry form for bulk hauling, bagging, processing
Low thermal conductivity - an ideal element in insulating refractories, geothermal cements, stuccos, and more
Low oil absorption - due to the non-porous surface and low surface area shape
Resistant to acids and alkalis, neutral in pH - do not react with the products in which they are used.
Hard, glassy shell - impermeable to liquids and gases, erosion and weather resistant
