Description
Technical field
This utility model relates to a kind of powder body strength tester, belongs to " G01N tests or analysis of material " technical field in International Patent Classification (IPC) by means of the chemically or physically character measuring material。
Background technology
We often utilize powder body yield pressure compression deformation needed for the relation of principal stress change in volume Yu pressure to analyze powder body, the i.e. variation relation of principal stress and powder density, binding time and yield strength variation relation, and after the process of the north, river journey equation of linear regression, obtain the meaning of constant u, v；In the journey equation of linear regression of the north, river, gained u value is more big, it was shown that powder body is easily compressed into less volume, and namely compressibility is good, constant v=1/P0, for coefficient of compressibility, it is the mark that declines of the porosity of unit pressure powder layer, v value is relevant with the plasticity of powder body, so v value sign powder complexity by compression, greatly, then plastic deformation can occur powder need less pressure v value。
It is generally acknowledged that compression process can be divided into mould to fill according to the sequencing that compression process occurs, particle slides and resets the densification that causes, the elastic-plastic deformation of grain and broken or not have the consolidation crushed。Powder body is subject to surrender compression and occurs at powder body from production and processing, storage, in the links such as transport, each link carries out under different internal and external environment changes, and powder body is subject in cohesiveness own and displacement technical process the impact of the environmental change of internal temperature, humidity；Such as in the pipeline of high temperature, in cold storage transport in winter, or at moist rainy weather high humidity, the impact of powder body is the very big factor can not ignore by these environmental changes。
Existing powder body strength tester is typically under room temperature state to adopt tablet machine mode as pressing mechanism, powder body is positioned in the mould of fixed volume, the powder body of pressurizing mold intracavity is carried out by automatically controlled or hand-driven tablet machine, to reaching under fixation pressure state, take out powder body gage measuring powder thickness, by computing formula, adopting artificial calculating to obtain data, there is following defect or deficiency in it:
1, structure is rough, and automatization level is low, it is impossible to obtain powder compression intensity process delta data accurately；
2, measure powder body to need to be removed from the molds measurement thickness data, when powder body can be subject to artificial destruction from the process that mould takes out, during with gage measuring, the error of manual operation and the error impact of measurer itself cause a deviation relatively big, and this process operation is very careful, and operation easier is big；
3, adopting under manual compression state, powder body after being under pressure in compression, because of the impact of the uniformity person's of being operated speed of operation speed of powder compression pressure process and strength size in Manual pressurizing process；
4, existing measurement can only compress powder body under room temperature state, it is impossible to simulation powder body is in different environments such as high temperature, low temperature, the compressive strength characteristic under humidity, temperature alternating, ozone, ultraviolet, hernia ambient condition；
5, between mould and tablet machine pressing mechanism it is separate type, the position on pressing mechanism is put into after installing mould powder body, cannot ensure every time the same, deviation because of position, cause that in mould, in powder body process by compression, pressure experienced is different, under same sample is repeatedly tested, repeatability is bad；
6, without degassing function in die design process, mould chamber air cannot be got rid of, and occurs that the pressure suffered by powder differs with actual value, also have when test powders sample is superfines, such as during nanoscale micropowder, because of atmospheric pressure from ejection die cavity, test crash can be caused。
