Application method and purpose of micropore lightweight material for treating desert

The present invention discloses an application method and purpose of a micropore lightweight material for treating a desert. A porous loop body is made of the micropore lightweight material, the porous loop bodies are stacked mutually and mixed in the desert to be integrated, and greening wild grasses or rod shrub are planted in the porous loop bodies. The porous loop bodies are made of the micropore lightweight material with good water absorption, moisture-keeping and ventilation property, and are stacked horizontally and fixed in the desert, thus the effect of greening and treating the desert is rapid, the greening is stable and reliable, and the desert after greening is durable, also the greening method is environment protection, and is capable of comprehensively treating and greening the desert by large areas, thereby the soil is prevented from erosion, the ecologic environment is improved, thus it is capable of being favorable to a good health, improving economic development, quickening ...

Plasticizing high-aluminum ceramic support roller

The present invention relates to a toughening high-alumina porcelain supporting roller, namely a tempered porcelain supporting roller, and the component of which comprises mullite, calcined alumina powder, zircon, zirconium oxide and clay, and rare-earth oxide, adhesive and lubricant. The supporting roller is obtained by adopting dry powder, high-strength static pressure for molding, and roasting at a high-temperature for 1480-1500. The invention uses the porcelain instead of the steel, sufficiently exerts the ceramic material characters of good wearing-resisting property, strong corrosion resisting property, high temperature oxidizing resisting, light specific weight, large compression strength and the like. At the same time the breakability problem of the ceramic is settled with the special crystal structure of the zirconium oxide toughening, high-alumina mullite and the supporting roller is stable at high temperature. The service lifetime is far better than the common ceramic and has ...

Lightweight high Ni content catalyst and preparation thereof

Light-weight high-nickel catalyst and preparation method thereof

The present invention discloses a light high-nickel catalyst for heavy oil cracking and its preparation method. It is made up by using light porcelain powder as aggregate, using bauxite and light porcelain clay as binding agent and adding pore-forming agent and feldspar powder. Its preparation method includes such processes of material selection, pulverizing, proportioning, mixing, granulating, sintering, nickel impregnating and baking. Said invented product has good porosity, high nickel content, good catalysis effect, light specific gravity, high mechanical strength, anti-quenching and rapid heat resistant, and long service life.

POROUS PACKING MADE FROM LIGHT PORCELAIN

Application method and use of water seepage sand-fixation ring in desert afforestation

The invention discloses a usage and a use of a water permeable sand fixation ring in desert greening. The water permeable sand fixation ring is a porous ring body made from lightweight microporous ceramic material; the porous ring bodies are put on the desert with cement mortar filled and poured into spacing between the porous ring bodies, thus the porous ring bodies are connected into a whole body; then nutritional soil is filled in the porous ring bodies, and finally grass seeds or shrubs for greening are planted in the nutritional soil. As the porous ring bodies which are made from the lightweight microporous ceramic material and have effects of water absorption, moisture keeping and air permeability are mutually horizontally piled up and covered on the desert, the method for applying the water permeable sand fixation ring to the desert greening has quick effect on greening and the desert control, and stable and reliable greening, which can cause the desert to be used for a long time ...

POROUS PACKING MADE FROM LIGHT PORCELAIN

The present invention refers to the porous packing material made of light porcelain. It is used as column packing in chemical, metallurgical, and gas industry with advantages of corrosion resistance, high compressive strength, non-deformation, good wettability and mass-transfer efficiency, long service life, and low cost. The present packing material consists of high magnesium clay 60-80 wt%, wood saw-dust 20-30 wt%, silica powder 2-9 wt%, with chemical composition of SiO2 61-68%, Al2O3 0.8-2.5%, Fe2O3 3-4%, CaO 1-2%, MgO 24-30% and KNaO 1-2%.
