Abstract
The present invention relates to a kind of static pressure shaped blank composition of ceramic rod (bar), it is by selected kaolin 20～40%, emergy 20～40%, αYang Hualv 20～40%, grog 5～15%, water 12～22% and add 1～4% methylcellulose gum and form.With the ceramic rod idiosome that above-mentioned stock is made, not yielding, density is even, and shrinkability is little, and the calcining yield rate reaches more than 80% after waiting static pressure, and bending strength, volume density, linearity etc. also all are better than the ceramic rod that adopts other billet compositions made.
Description
The present invention relates to the composition of the used stock of a kind of ceramic rod hydrostatic pressing.
Produce ceramic rod with diverse ways, the composition of used stock is often respectively different to some extent.The ceramic rod that existing extrusion process, slip casting method are produced, the composition of its stock is not suitable for the hydrostatic pressing method.The hydrostatic pressing method of ceramic rod is meant idiosome is placed special mould, and putting into oil is that the autoclave of medium pressurizes.Produce ceramic rod with isostatic pressing method, except that the special mould of needs, also need to select for use different billet compositions.Isostatic pressing method is by tube extruding machine stock to be expressed on the internal mold that a stainless steel tube makes, and makes stock form a tubular idiosome, just puts the oil resisting rubber external mold then, after the sealing both ends, inserts in the autoclave and pressurizes.Do not have the following stock of situation of external mold setting to be expressed to equably on the stainless steel tube having only internal mold, and form tubular idiosome, require stock that more stable shaping degree is arranged.Existing various billet composition all satisfies this requirement unsatisfactorily.
Purpose of the present invention is exactly to seek a kind of billet composition that can be suitable for hydrostatic pressing method production ceramic rod.
Stock of the present invention is made up of mixing such as selected kaolin, emergy, αYang Hualv, grog, water and methylcellulose gum.Its specification is: selected kaolin 250～350 orders, emergy 60～120 orders, αYang Hualv 3～15 μ, grog 20～80 orders.Grog is that the ceramic rod of subscription rate is pulverized and formed, and adds an amount of grog and can work to reduce the ceramic rod idiosome and shrink and distortion.The ratio of components of above-mentioned stock is (weight %): selected kaolin 20～40%, and emergy 20～40%, αYang Hualv 20～40%, grog 5～15%, water 12～22% adds 1～4% methylcellulose gum.
The present invention is further illustrated below in conjunction with embodiment.
Get the selected kaolin 230kg of 300 purposes, 100 purpose emergy 250kg, the αYang Hualv 220kg of 8 μ, 60 purpose grog 120kg, water 180kg adds the methylcellulose gum of 20kg in addition.Promptly can be used as ceramic rod hydrostatic pressing stock after stirring evenly with stirrer.
With the ceramic rod idiosome that stock of the present invention is shaped, have that shrinkability is little, density evenly, advantage such as not yielding; Through waiting static pressure pressurization back to calcine, its yield rate reaches more than 80%, and bending strength, volume density, linearity etc. also are better than the ceramic rod that adopts other billet compositions made.
