Description of drawings
The measuring method of the Density Distribution of the green brick of the preferred embodiments of the present invention and compacting, and the method that generates suitable examining report will describe in detail by accompanying drawing.
Accompanying drawing shows the present invention, in the accompanying drawing:
Fig. 1 is the synoptic diagram of the present invention that has basic module;
Fig. 2 has illustrated from three different views and has been used for transmitting the green brick and it is immersed in the basket of mercury;
Fig. 3 shows three green bricks, and is divided into the Density Distribution that 16 specimen are used to measure the green brick with every;
Fig. 4 shows the examining report of the green brick that comprises four compactings.
Embodiment
Equipment shown in Figure 1 is density and definite Density Distribution of working sample in the following manner:
When specimen is immersed in the mercury, and after mercury is static, the buoyancy of the basket of the connecting gear that has specimen 7 of scale 4 measurement submergences, the buoyancy of the basket of the submergence of connecting gear 7 is known constants, it is cut from gross buoyancy, then determine the buoyancy of specimen 1.
Weight (g) * 13.54 (g/cm
3)/buoyancy (g)=volume density (g/cm
3)
Wherein 13.54 is the density of water at normal temperature silver.
Fig. 2 has illustrated the structure that connecting gear 7 specimen are chosen basket from three different views.The top of basket container 12 is sealed by a lid 13.Described lid 13 rotates around turning axle 15 above bar 14.The spring 16 that engages with bar 14 makes and covers 13 and remain on make-position.Similarly, swivelling cover 17 is positioned on the turning axle 18 of basket 12 bottoms.Described lid 17 remains on make-position by spring 20, and spring 20 engages with bar 19.Basket 12 is fixed on the device 21, and device 21 is positioned on the piston rod of cylinder E (see figure 1).Fig. 2 b shows the basket 12 that covers 13 and 17 closures.Described lid 13 and 17 transmits and basket all remains on closure state when being immersed in the mercury in specimen.
Fig. 2 C is the rear view of basket 12.Top cover 13 is connected with another bar 22 as can be seen, and guide roller 23 is positioned on the bar 22.When basket 12 was elevated to the extreme higher position, this guide roller was along the groove of the bending (not shown) of moving.Thus, lid 13 is opened, and therefore the ceramic tile sample enters in the basket of opening.The lid 17 of bottom is equipped with bar 24 equally.Guide roller 25 is positioned on the bar 24.Described guide roller 25 is activated by lever system by cylinder D, thereby opens basket.After the buoyancy measurement was finished, specimen was removed (see figure 1) by the slope 26 of stretching out.
With reference to figure 3, shown that circuit 9 is calculating mean values how simultaneously, thereby made that the explanation of Density Distribution is simpler.For this reason, calculate three class mean values: promptly
A) mean value of the fringe region of each ceramic tile,
B) mean value of each full sized brick, and
C) mean value of total stampings comprises three blocks of ceramic tiles in this example.
The specimen that is positioned at the ceramic tile edge can calculate the mean value of fringe region.The mean value of different fringe regions just provides ceramic tile to depart from the information of the situation of rectangularity.
The overall mean value of each ceramic tile just provides the information of relevant ceramic tile dimension difference.
The mean value of total stampings can be used for controlling the pressure of determining in the pressing process, thereby in pressing process, keep suitable pressure, because different density different shrinkage factor in the time of can causing firing, described shrinkage factor can cause surface deformation, and the difference of color during glazing.
After test is finished, test report is exported on display screen 10 and/or printer 11 by the electronic installation of machine, comprise the whole test result informations of each specimen, three class mean values and other information of interest, out of Memory can be by operator's input of equipment, as pressing pressure, operator's identity, the humidity of particle etc.
