Abstract
The production process of fine haydite with bauxite as basic material includes the steps of: adding clay, lanthanide metal oxide, MnO2, MgO and other supplementary material, and grinding into fine powder; mixing with water, adhesive, dispersant and defoaming agent to form slurry; pumping the slurry with pump and spraying with spray gun into drying tower to obtain dried pellet, and sintering in kiln to obtain the product. The fine haydite product has compression strength upt to 86 MPa, breaking rate less than 5% and flow conductivity at 60 MPa closed pressure up to 60 sq micron.cm. The fine haydite product may be used as sand for precise casting resulting in low precise casting cost and high surface smoothness and as petroleum fracturing proppant.
Description
Technical field
The present invention relates to a kind of making method of haydite, particularly a kind ofly not only can be used as high-strength compress supporting agent for coarse oil but also can be used as the haydite making method of precision casting with sand.
Background technology
Propping agent is the critical material that oil gas deep-well, ultra deep well fracturing technology are special procured, and plays an important role to improving oil, gas output and prolonging work-ing life oily, gas well.At present, the above high strength small particle size ceramsite propping agent of 69MPa mainly is an external product, exists the high problem of cost of manufacture on manufacture craft.Then there is the not satisfactory problem of performance index in home products.And if existing propping agent uses with sand as precision casting, the external product price is too high, and home products then can make the surface quality of continuous castings instability.
Summary of the invention
The objective of the invention is to, a kind of making method of fine haydite newly is provided.The fine haydite that this method is made, cost of manufacture is lower, and product performance index has reached external similar level.Product both can be used as propping agent and had used, and can be used as precision casting again and used with sand.
The present invention realizes like this.Make fine haydite by following step, described umber is weight part.
A, batching: with 100 parts of Al
2O
3It is base-material that content is not less than 70% bauxitic clay, adds following auxiliary material, 2～20 parts of clays, 1～10 part of lanthanide metal oxide, 0.3～3 part of Manganse Dioxide, 0.1～3 part in magnesium oxide; Base, auxiliary material are worn into fine powder after mixing altogether, get the A material.
B, make slip: add the defoamer of dispersion agent, 1～10 ‰ of water, 0.3～3% binding agent, 1～10 ‰ of A material weight 30～70% in the A material, the slip that obtains after stirring is the B product.
C, granulation: with operating pressure 0.1～3.0MPa, flow 0.1～10m
3The pump of/h by being drilled with the spray gun of 0.1～3.5mm eyelet, is injected the B product in the drying tower of 200～600 ℃ of temperature, and the base ball that obtains particle diameter 0.01～0.35mm is the C product.
D, sintering: the C product are sent into kiln, and by 1000～1500 ℃ of sintering temperatures, sintering time was fired in 0.5～5 hour, got finished product.
In the making method of above-mentioned fine haydite; Among the step b, described binding agent is PVA-217 or PVA17-88 water soluble resin glue, and described dispersion agent is DA-40 or A-15 solution, and described defoamer is BYK602 or BYK603 solution.
Compared with the prior art, the present invention has improved manufacture craft, makes the fine haydite that the present invention makes, the product performance index height, and cost of manufacture is low.The product that the present invention makes, ultimate compression strength reaches more than the 86MPa, and the finished product percentage of damage is no more than 5%, and flow conductivity reaches 60 microns under the 60MPa locking pressure
2Centimetre.The fine haydite that the present invention makes, because cost is lower, intensity height, epigranular also can be used as precision casting and use with sand, can reduce the surface smoothness that essence is cast this and improved foundry goods.The present invention have that technology is simple and easy to do, production efficiency is high (1.5～3t/h), cost of manufacture is low, product granularity is normal state uniform distribution, characteristics that ultimate compression strength is high.Can be used in the production of petroleum fracturing propping agent and foundry sand.
