Alumina ball stone

(A) microcrystalline wear alumina article 1, ball stone: alumina ball stone depending on the method for forming sub repression ball and roller-ball, pressing the ball by cold isostatic pressing, with flange, specifications from 30-120 range; roller-ball shaped rolling fashion, no brim, circular, specifications from 0.5 to 40. 2, brick lining: aluminum lining brick divided according to the shape: rectangular brick, trapezoidal bricks, shaped bricks. Its common specifications from H40 to (H on behalf of its thickness) H100. The length of the bricks are 150mm, width varies (ie brick ramp and down into different width, straight up and down as wide brick, thin brick is typically 25mm wide). 3, lining: aluminum lining according to different uses can be divided into flat liner, liner welding, pipe lining, is produced by molding, welding liner and the liner flat compared to pass for more than one welding hole, the width of the upper and lower pipe liner and the liner plate is not the same maximum use is inconsistent. Its specifications are more, we can meet different customer needs. 4, lining / Mosaic: lining / square and hexagonal mosaic have different thicknesses size models. Due to small size, usually in the molded on sticking to the gauze, also a loaded into the film when packing. 5, shaped pieces: alumina shaped pieces according to their types into the pipe, cutting pieces of ceramic parts. Alumina products can be more than the production of other specifications according to customer demand, to meet customer needs. Alumina article produced by alumina content 75%, 80%, 90%, 92%, 95%, ranging from 99%. Its physical and chemical properties have an alumina content, bulk density, water absorption, impact resistance, abrasion equivalents, Mohs temperature, such as alumina content of greater than 90%, which should be greater than the corresponding bulk density equal to 3.60. Resulting in substandard product quality appearance defects spotted, piebald, bubbles, cracks, scoliosis, etc. These are standard products in the test needed is qualified according to the company to develop corporate standards testing manufactured products. Tons of stone balls usually with small package bags, single bag weight of other aluminum products 25KG, lining brick, lining a cardboard box or wooden packaging, etc., shall be marked with product name, size, weight and other signs on the packaging. (B) Calcined α- Alumina Powder Company's existing three domestic advanced high-temperature calcination a- alumina powder production line. Depending on needs, the formation of a dry pressing, hot casting, refractories, casting stereotypes, structural ceramics granulated powder five series. Calcined α- alumina powder can be widely used, such as electronic equipment, structural ceramics, refractory, wear-resistant materials, polishing materials and other industries. (C) Petroleum oil fracturing proppant fracturing proppant is our own research and development production and product development as a key industry, the focus is now put into ultra tight / shale gas special oil fracturing proppant (≤1.55 g / cm3. ), low density proppant fracturing of oil (1.70 g / cm3). Our self-developed ceramic proppant with low-grade bauxite and industrial solid waste as the main raw material crushed to a fine powder after fine grinding, together with various additives, repeated kneading, granulation, polishing, high temperature sintering, has strong corrosion resistance, high strength, smooth surface, regular shape and other characteristics, is the ideal material for deep oil and gas wells in low permeability fracturing. Proppant used in oil and gas deep mining, the high pressure low permeability deposit is closed after fracturing treatment, the hydrocarbon-bearing formation split, passage of oil and gas from the cracks formed in the collection out. Ceramic proppant material along with high-pressure solution is filled into the formation in rock fissures, cracks do not play a supporting closed due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production. The main physical and chemical indicators of size, roundness, sphericity, bulk density, apparent density, acid solubility, turbidity, compressive strength, etc. These physical properties determine the quality of the proppant conductivity and closed under pressure. Roundness and sphericity use to describe the shape of the proppant, they increase the porosity in order to improve and make more uniform stress distribution. Now I produced shale gas with low density and high strength proppant fracturing of unconventional ultra low density proppant has a density, broken rate, low acid solubility and high compressive strength characteristics, the production process is reasonable, stable performance ; industrial production of the product will break the market monopoly of international brands, provide a strong impetus for the development of shale gas in China.
