Description
Technical field
The present invention relates to quick measuring method of a kind of density and device, relate in particular to a kind of measurement mechanism that is used for measuring loose porous solid objects density.
Background technology
The density of Measuring Object adopts Archimedes principle usually; Promptly weigh up the aerial weight of object, again object is immersed in the liquid medium, weigh the weight of object in liquid medium; Through calculating the density of object, liquid medium used herein is water or kerosene normally.This method is suitable for for most of objects, however for loose porous object, for example: the measurement of the density of fire resistive material, powder molded blank etc., just can't adopt.This is because water or kerosene soak into most of objects, when object immerses in the liquid medium; Water or kerosene can be penetrated in the internal voids of object and go; The volume of the object of measuring like this, just inaccurate, the density that calculates is also just meaningless.
Therefore, the object that traditional measurement is loose porous, for example: the method for the density of fire resistive material, powder molded blank etc. does, at first the aerial weight of weighing object; Then with heating paraffin, treat its fusing after, object is immersed in the paraffin fully, take out object, treat the complete cooled and solidified of paraffin of body surface after, scrape off the unnecessary paraffin wax of body surface, utilize the volume of drainage Measuring Object; And then calculate the density of object.This measuring method requires operation very careful, otherwise error is very big.For example, if object does not immerse in the paraffin fully, then the pore of body surface can not be lived by the paraffin complete closed, and moisture can get into the inside of object during measurement; Body surface is scraped in the cured process, because the intensity of blank is lower, is easy to breakage, and at this moment, blank needs the step before the repetition, waxdip again; Moreover because the body surface wax sealing, even few again paraffin, it always has volume, and therefore, the volume that object is measured and its true volume be difference to some extent still.
Obviously, the density method of the object that traditional measurement is loose porous, very loaded down with trivial details, and also time-consuming.Often need spend several hours time, and the measurement result degree of accuracy is not enough.
Summary of the invention
Quick measuring method of a kind of density of the present invention and device, the technical matters that is solved is the deficiency that overcomes prior art, has solved the time-consuming and accurate inadequately problem of measurement result of loose porous object density measurement of measuring.
Quick measuring method of a kind of density of the present invention and device comprise 3 parts: go up meausring apparatus, main frame, following meausring apparatus.The above part of host platform is called meausring apparatus, and the part below the lower draw-bar of main frame bottom is called meausring apparatus down.
Last meausring apparatus comprises: glass hurricane globe (1), weighing plate handle (2), weighing plate (3), push-down head (5), screw (13), nut (4), by the support (bearing) (11) of the container (9) of the support tube (or bracing frame) (8) of weighing object (6), the liquid medium (7) that is used for weighing, weighing plate, carrying liquid medium, weighing base (10), carrying liquid media Containers.
Main frame (14) shows that to the weight and the density of institute's weighing it has weighing sensor (12) above platform, and support column (17) is arranged below.
Following meausring apparatus comprises: be used for weighing lower draw-bar (15), lifting rope (16), be used for weighing suspension weighing plate (20), be used for the liquid medium (21) of weighing, the container (18) of carrying liquid medium.
For the density measure of the lower material of the porosity, for example, ferrite core, pottery, metal etc.; Can use meausring apparatus earlier; Weigh up the aerial weight of object, use meausring apparatus down again, the weight of weighing object in liquid medium; Main frame then can be according to the density of setting automatic computing object, and the used liquid medium of following meausring apparatus can be water, kerosene etc.Adopt this method more convenient for block object densification, that volume is bigger.
For loose porous object, for example: fire resistive material, powder molded blank etc., or density is less than 0.8g/cm
3Object, must adopt go up meausring apparatus, weigh up the aerial weight of object, after the weighing object is pressed in the liquid medium again, the weight of weighing plate, main frame then can be according to the density of setting automatic computing object, the used liquid medium employing of last meausring apparatus mercury.If weighing density is less than 0.8g/cm
3Object, then liquid medium adopts water or kerosene etc.
The invention has the beneficial effects as follows: utilize mercury that the most solid material is not soaked into; Perhaps wellability is relatively poor; It is difficult for being penetrated in the space of object, thereby is fit to measure loose porous this characteristic of object, the density of coming directly to measure fire resistive material, powder molded blank.Because this method of employing is convenient and swift, whole process only needed get final product for 10 seconds.And the method for traditional measurement green density, since very loaded down with trivial details, need melted paraffin, waxdip, scrape cured and the repeated multiple times weigh, and spended time often needs several hours, and the result is not necessarily very accurate.Measurement result of the present invention is not only accurate, and fast, saves lot of manpower and material resources simultaneously, can be used for on-line quick detection, to improving and the quality of control product has very important significance.
