Abstract
The grain size composition in zirconia base ceramic formula for preparing cylinder casing belongs t the field of structure ceramic preparation technology, and the grain size of main component zirconia powder body in the ceramic formula for preparing cylinder casing includes: one kind of 60-80 wt% of zirconia powder boby whose average grain size is 0.2-0.5 micrometer, and another kinds of 20-40 wt% of zirconia powder body whose average grain size is 0.6-1.2 micrometer, in the zirconia powder body 2-3 mol% of yttrium oxide, 0.5-5 mol% of magnesium oxide, 4-15 wt% of alumina and proper quantity of dispersing agent are added, and undergone the processes of ball-grinding, mixing, spray-granulating, isostatic pressure forming and firing at 1460-1520 deg.c so as to obtain the invented ceramic cylinder casing whose service life is above 2400 hr.
Description
Technical field
The present invention relates to prepare the oil drilling pump with the size composition in the zirconia-based ceramics prescription of cylinder sleeve liner.Belong to the structural ceramics field.
Background technology
Carry drilling mud when drill pump is oil drilling and take the bottom rock chip out of well outer visual plant.Use is contained the erosion corrosion effect of sand, alkaline mud, the inefficacy that easily is worn of its cylinder sleeve liner, and it is frequently changed or keeps in repair and has a strong impact on drilling well production efficiency.
Existing cylinder sleeve liner mostly is metallic substance and makes, and for improving the work-ing life of cylinder sleeve, patent " EP.162.284.A " proposes the ceramic liner liner of 96 aluminum oxide materials, the traditional metal materials cylinder sleeve life-span can be extended to 800～1000 hours by 200 hours.This stupalith have the deficiency of aspects such as production cycle length, complex process, firing temperature height, and the work-ing life that can reach is still lower because of adopting grouting process and twice firing.
Summary of the invention
The object of the invention is to provide the size composition in a kind of zirconia-based ceramics prescription for preparing cylinder sleeve, is easy to realize that with the cylinder sleeve of the ceramic material of this particle diameter prescription mass production and technology are simple, low cost of manufacture, long service life.
The basic components of the toughened zirconium oxide ceramic that the present invention adopts is: based on zirconium white, add 2～3mol% yttrium oxide, 0.5～5mol% magnesium oxide, 4～15vol% aluminum oxide.On above-mentioned prescription basis, add an amount of dispersion agent, as 0.5～1.5wt% ammonium polyacrylate, cooperate 55～70wt% water, the common process for preparing by pottery carries out ball milling mixing, mist projection granulating, isostatic pressing, burns till 1460～1520 ℃ of scopes.Invention part of the present invention is: require principal constituent zirconium white raw material to form with the powder of two class particle diameters: wherein a class account for 60-80wt% be median size at 0.2-0.5 μ m, the another kind of 20-40wt% of accounting for is that median size is at 0.6-1.2 μ m.
The invention has the advantages that: the one, can regulate the processability of material, simultaneously by the more coarse grained adding of part, material is reduced in the contraction of sintering process, be beneficial to improve and burn till yield rate; The 2nd, the part meal is introduced can effectively reduce whole raw materials cost; The 3rd, in conjunction with other components in the basic components, this grating is handled the fracture toughness property that can further improve material.
Embodiment
Embodiment:
By 50 kilograms of prescription weighing zirconia powders, wherein 35 kilograms is the following fine powder of 0.5 μ m, 15 kilograms is meal about 1 μ m for median size, 2.54 kilograms of yttrium oxide, magnesium oxide 350 grams, 1.8 kilograms in aluminum oxide adds 36.5 kilograms in water, 547 gram ammonium polyacrylates, ball milling mixes, behind granulation, isostatic pressing cylinder sleeve, burnt till 3 hours at 1490 ℃.Make cylinder jacket material intensity and reach 600MPa, fracture toughness property reaches 12Mpam
1/2, ceramic-lined through inside and outside circle processing, with the respective metal overcoat after interference fit, work-ing life can be above 2400 hours.
Claims (1)
1. the size composition in the zirconia-based ceramics prescription for preparing cylinder sleeve, preparation cylinder sleeve stupalith is based on zirconium white, add 2～3mol% yttrium oxide, 0.5～5mol% magnesium oxide, 4～15vol% aluminum oxide, 0.5～1.5wt% ammonium polyacrylate dispersion agent, 55～70wt% water, mix through ball milling, mist projection granulating, isostatic pressing, burn till at 1460～1520 ℃ and to be prepared from, it is characterized in that: the zirconium white raw material is made up of the powder of two class particle diameters: wherein a class median size is that 0.2-0.5 μ m accounts for 60-80wt%, and another kind of median size is that 0.6-1.2 μ m accounts for 20-40wt%.
