Ceramic honeycomb is a honeycomb-like shape of the last three decades the development of new ceramic products. From the earliest use in small autocatalysts today widely used in chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries, and more widely, the development prospect is considerable.
Ceramic honeycomb shapes composed of countless identical holes, the largest number of holes has reached 20 to 40 per square centimeter, the density of 4 to 6 grams per cubic centimeter, the water absorption of up to 20%. Due to the characteristics of the porous thin-walled, greatly increasing the geometric surface area support and improve the thermal shock resistance, the products, the triangular mesh apertures and the main square, triangular better endurance than the Quartet, also more than the number of holes more, it is especially important as a catalyst support. With the reduction in the number of holes per unit area of the carrier and improve cell wall thickness of the ceramic carrier thermal shock trend is to increase the temperature of thermal shock damage is increased. Therefore, the ceramic honeycomb must be reduced expansion coefficient and increasing the number of holes per unit area. Coefficient of thermal expansion is the main performance indicator is the current level of foreign α25-1000 ºC ≤1.0 × 10-6 ºC -1, there is a certain gap between domestic and contrast, but this gap is getting smaller and smaller. The first production of cellular ceramic raw materials are mainly kaolin, talc, aluminum powder, clay, and today has been a breakthrough, especially diatomaceous earth, zeolite, expansive soil and refractory applications, ceramic honeycomb increasingly widespread, more and more performance it is good.
because of its high strength, high temperature resistance, corrosion resistance, wear specificity can be widely used in various fields of environmental protection, such as automobile exhaust emissions.
for micro-filtration, ultra-filtration and nano filtration thin porous ceramics used in the development of ceramic and polymeric film inorganic ceramic membrane began century American scientists first porous ceramic membranes to separate caustic UF 6 isotopes. Since the inorganic film SiO 2, Al 2 O 3, MgO, ZrO 2, TiC, UC and other inorganic silicate material prepared by a polymer having an organic thin film incomparable superiority, from the 21st century, the development and application of inorganic ceramic membrane It has been further developed, in addition to the traditional nuclear industry, aerospace, food industry, chemical, biological and other industrial applications and development in the field of the environment in particular attracted the attention of the world.If you are interested in our products, please contact us for more technical detaills.
