Abstract

The invention discloses ceramsite and a production method thereof. The ceramsite comprises the following raw materials by weight percentage: 40 to 99.5 percent of high alumina fly ash or high alumina coal slag and 0.5 to 60 percent of bond, and 1 to 23 percent of auxiliary material is particularly added. The above raw materials are ground, dried and burned to form the finished product, so the strength, the fire resistance and the duration of the product are multiplied, and the ceramsite can be used for the production of particular concrete aggregate with the high strength of more than 60Mpa and the heat-preserving and heat insulation materials with high fire resistant requirement. At the same time, the ceramsite can be used for proppant for oil and gas well cracks. Compared with the conventional proppant, not only the density is low, the strength is high and the performance is excellent, but also the expensive and rare alumina fire-resistant clay resource can be saved, and the comprehensive application of the resource can be realized. Compared with the prior process, the production method is more energy-saving and more environment-friendly, and favors the industrialized mass production.

Description

A kind of haydite and preparation method thereof
Technical field
The present invention relates to that a kind of high-grade concrete gathers materials with haydite and fire-resistant, lagging material is used haydite, also relate to a kind of oil, the employed haydite of Natural gas extraction borehole operation (being also referred to as ceramic fracturing crack propping agent).
Background technology
Under the high locking pressure of haydite in oil, Natural gas extraction borehole operation process that oil, gas well fracturing crack propping agent are adopted; Fill it in the rock fracture in hyposmosis mineral deposit; Play supporting crack not stress discharge and closed; The material that lets oil, gas from the passage of crack, compile, thus high flow conductivity oily, gas guaranteed, increase oil, gas well output.
China patent CN1085288 its to disclose a kind of be raw material with roasting bauxite, through multistage pulverizing, batching, dry method fine grinding, add that water mixes the material of rolling over, doze, granulation sintering and a kind of with α-AL 2O 3The high-density intensity ceramsite propping agent of phase.
China patent CN1393424 it discloses to be raw material with light-burned bauxite, to be aided with Fe a kind of 2O 3, MgO, auxiliary materials such as MnO and uncommon native oxide compound, through multistage pulverizing, special batching dry method fine grinding etc., with the similar technology of preceding CN1085288 make a kind of with α-AL 2O 3Be principal crystalline phase mutually, high-density, high-strength ceramic proppant.
It is raw material with sintered bauxite grog and kaolin, red soil that China patent CN1367306 discloses a kind of, through technologies such as dry method fine grinding make a kind of, with α-AL 2O 3Phase, mullite are the principal crystalline phase low-density ceramic proppant.
More than three kinds of ceramsite propping agents be main raw material all with bauxitic clay (grog); This raw material is more and more rare and more and more expensive; Particularly patent CN1367306 adds the secondary mulliteization that raw materials such as kaolin, red soil certainly will cause goods in bauxitic clay, and quality product is difficult to stablize.And the above three therapeutic methods of traditional Chinese medicine all adopts the dry method fine grinding technology, and this method energy consumption is high, and investment is big, grinds the big and irrational distribution of back particle diameter, is difficult to reach the requirement of high-quality product; And uncontrollable discharge is difficult to control, and environmental pollution is serious.
China make about flyash (slag) that high-grade concrete gathers materials with haydite and fire-resistant, lagging material is very many with the patent of haydite, but the haydite of made is fire-resistant, lightweight heat-proof performance, intensity can not meet the demands.
Summary of the invention
The technical problem that the present invention will solve provides a kind of a kind of low density that trade waste aluminous fly-ash or high-alumina fly cinder produce or extremely-low density, HS, lightweight, fireproof haydite of utilizing.
