Problems solved by technology

In this method, each ceramic piece must weigh its mass in three different environments to calculate its bulk density, which is a large workload, increases the source of error, generates error accumulation, and increases the Chance of damage during weighing, thus affecting the accuracy of its bulk density

Embodiment Construction

[0016] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0017] In Fig. 1, the water cup 2 is placed on the weighing pan 10 of the electronic balance 1, the hanging basket 5 is connected to the support 3 by a thin copper wire 6, the hanging basket 5 is immersed in the water in the water cup 2, and the support base 7 Distribute the load evenly on the electronic balance bearing platform 8. The total mass of the water cup and water should be less than the range of the electronic balance. When the system is in a balanced state, reset the balance to zero, and gently put the wet ceramic piece 9 with the surface wiped off moisture into the hanging basket 5. At this time, the value displayed on the balance is m, and the volume density of the ceramic piece can be calculated ρ = m 0 × ρ ...

Abstract

This invention relates to one ceramics volume intensity electron measurement device and method, wherein the device comprises electron balance, water contain cup, thin copper wire and hanging barrel, wherein, the electron balance disc is put with cup and has one rack with its base socket to distribute loads onto load bench; thin copper wire top end is fixed onto rack and its down end has handing barrel in cup water; in measuring, setting the electron balance as zero and to rest ceramics quality m0 and then boiling it for two hours for natural cooling off; sweeping off water in the barrel to read balance display values to compute ceramics volume intensity.

Description

Technical field: [0001] The invention relates to an electronic measuring device and method for ceramic bulk density. Background technique: [0002] At present, the Archimedes drainage method used to measure the bulk density of electronic ceramics is generally completed according to the following three steps: 1. Weigh the mass m of the dry ceramic sheet in the air 0 ; 2. Make the micropores on the surface of the ceramic sheet full and absorb water, and weigh its mass m when it is immersed in water 1 ; 3. Wipe off the moisture outside the holes on the surface of the ceramic sheet to keep it in a moist state, and weigh its mass m in the air 2 . then bulk density ρ = m 0 ρ 0 m 2 - m 1 (ρ 0 is the density...
