본 고안은 분체(粉體)의 분산성을 정확하고 용이하게 측정할 수 있게 하는 장치에 관한 것이다.The present invention relates to an apparatus that enables to accurately and easily measure the dispersibility of powder.
일반적으로 정밀화학분야나 제조업분야에서는, 어느 분상물질 또는 분체가 특정한 분산용액에 어느 정도로 분산되는지 혹은 그 분체의 표면처리가 어떠한 상태로 되어 있는지를 측정하는 경우가 있다.In general, in the fine chemical field or the manufacturing industry, it is sometimes measured to what extent the powdery substance or powder is dispersed in a specific dispersion solution or what kind of state the surface treatment of the powder is in.
이에 관한 방법으로서, 종래에는 눈금이 새겨진 비이커나 메스실린더에 분산용액을 채우고, 측정화 하려는 분체를 순수에 분산시켜 분사용액에 부운 다음 육안으로 관찰하여 소정의 눈금까지 분체가 가라앉을 때까지의 시간을 측정하고 기준 시료와 비교함으로써 원하는 분체의 분산성 및 표면처리 상태를 측정하였다.As a method of this, conventionally, a dispersion solution is filled in a beaker or a measuring cylinder with a graduated scale, the powder to be measured is dispersed in pure water, poured into a spray solution, and then visually observed until the powder has settled down to a predetermined scale. Was measured and compared with the reference sample to determine the dispersibility and surface treatment state of the desired powder.
이러한 종래의 측정방법은 눈대중에 의해 측정하는 것이므로 정확하고 객관성있는 데이터를 얻기 힘들뿐만 아니라, 관측자가 일일이 손으로 데이터를 작성해야 하는 번거로움이 있고, 또 분체의 침강상태를 계속 지켜 보아야 하기 때문에 측정에 많은 인력과 시간이 투입되는 단점이 있었다.Since the conventional measuring method is measured by the eye mass, it is difficult to obtain accurate and objective data, and it is cumbersome for the observer to write the data by hand, and to keep watching the sedimentation state of the powder. There was a disadvantage in that a lot of manpower and time was spent.
이에 본 고안은 상기한 종래의 단점을 해소하기 위하여 전자식 저울에 분체채취대를 매달아 그것을 비이커등의 분사용액에 담그고, 시료분체를 분산용액에 분산시켜 분체가 가라앉음에 따라 변화하는 분체채취대의 무게 변화를 전자식 저울로 측정하여 이를 기록장치를 통하여 프린트함으로써 분체의 분산성 및 표면처리 상태를 정확하고 용이하게 측정할 수 있게하는 장치를 제공함에 그 목적이 있다.In order to solve the above-mentioned drawbacks, the present invention suspends the powder collection table on an electronic scale and immerses it in a spray solution such as a beaker, and disperses the sample powder in a dispersion solution to change the weight of the powder collection table as the powder sinks. It is an object of the present invention to provide an apparatus for measuring the change with an electronic balance and printing it through a recording device so that the dispersibility and surface treatment state of the powder can be accurately and easily measured.
그리고, 본 고안에 의하면, 특정한 분체를 기준으로 하여 분산용액의 종류를 바꿔가면서 분체의 분산성을 측정하면 분산용액들의 특성도 비교측정할 수 있는 이점이 있다.And, according to the present invention, by measuring the dispersibility of the powder while changing the type of the dispersion solution on the basis of the specific powder has the advantage that the characteristics of the dispersion solution can also be measured comparatively.
이하에 첨부 도면을 참조하면서 본 고안에 의한 분체의 분산성 측정장치를 상술한다.EMBODIMENT OF THE INVENTION The dispersibility measuring apparatus of powder by this invention is explained in full detail, referring an accompanying drawing below.
본 고안에 의한 측정장치의 정면도가 도시된 제1도에서, 참조 번호 1은 물체의 중량을 디지탈 방식으로 표시하는 전자식 저울을 나타내는 것으로써, 이 전자식저울(1)의 하부에는 추 장착고리(2)가 설치되어 분체채취대(3)를 매달 수 있도록 되어 있는데, 이 저울(1)은 기틀(7)의 상부에 탑재된다.In FIG. 1, which is a front view of the measuring device according to the present invention, reference numeral 1 denotes an electronic scale for displaying the weight of an object in a digital manner, and at the bottom of the electronic scale 1, a weight attachment ring 2 ) Is installed to suspend the powder collection table (3), the scale (1) is mounted on the upper portion of the frame (7).
이와 같은 상태에서 분체채취대(3)의 상단은 기틀의 상부 관통공(도시하지 않음)을 통하여 추장착고리(2)에 연결된 상태로 기틀(7)의 내부공간에 매달려 있게 된다.In this state, the upper end of the powder collection table (3) is suspended in the interior space of the base (7) in a state connected to the mounting ring (2) through the upper through hole (not shown) of the base.
그리고, 기틀(7)의 내측 하부에는 비이커 등과 같은 분산용액 수용용기(4)를 재치하는 동시에 이 용기(4)의 높이를 조절할 수 있는 용기 받침대(5)가 설치되어 있다.In the lower portion of the inner side of the base 7, a container support 5 is provided which can disperse the dispersion solution container 4 such as a beaker and adjust the height of the container 4.
이와같은 구조에 의해 측정자는 용기받침대(6)를 조정하는 것에 의해 분산용액 수용용기(4)를 기틀(7)내에 용이하게 삽입 또는 이탈시킬 수 있다.With this structure, the measurer can easily insert or detach the dispersion solution container 4 into the frame 7 by adjusting the container holder 6.
미설명 부호(6)은 용기 받침대(5)의 상판의 높이를 측정하기 위한 자(尺)를 나타낸 것이며 (8)은 전자식 저울(1)에 의해 측정된 분체채취대(3)의 중량 변화를 그래프 형태로 프린트하는 기록장치이다.Reference numeral 6 denotes a ruler for measuring the height of the upper plate of the container holder 5, and 8 denotes the weight change of the powder collecting table 3 measured by the electronic scale 1. It is a recording device that prints in graph form.
그리고, 기틀(7)의 측면은 측정도중에 공기 이동의 영향을 받지 않도록 투명한 아크릴판과 같은 판재로 밀폐 되어 있으며, 측면중의 어느 일방은 제2도에 도시된 바와같은 여닫이 문(9) 구조로 형성되어 여러 부품 등의 장착 또는 해체가 용이하도록 되어있다.In addition, the side of the frame 7 is sealed with a plate such as a transparent acrylic plate so as not to be affected by air movement during measurement, and one of the sides has a structure of a swing door 9 as shown in FIG. It is formed to facilitate the installation or disassembly of various parts.
다음은 상기한 구성을 가진 본 고안의 측정장치를 이용하여 분체의 분산성을 측정하는 과정을 설명한 것이다.The following describes the process of measuring the dispersibility of the powder using the measuring device of the present invention having the above configuration.
우선, 각 부품을 제1도와 같이 설치한 후 용기(4)에 분산용액을 채우고 전자식 저울(1)의 숫자를 영(zero)으로 맞춘다.First, after installing each part as shown in FIG. 1, the dispersion solution is filled in the container 4, and the number of the electronic scale 1 is set to zero.
그 다음, 측정하려는 분체를 순수에 분산시켜 용기(4)내에 붓고 그 시점을 측정개시 시간으로 하여 기록장치(8)를 가동시킨다.Then, the powder to be measured is dispersed in pure water, poured into the container 4, and the recording device 8 is operated with the starting point as the measurement start time.
시간(t)이 경과하면서 분체가 가라 앉음에 따라 분체채취대(3)에 무게가 가해져서 전자식 저울(1)에 숫자로 무게표시가 나타나며 전자식 저울(1)에서 출력되는 그 무게에 해당하는 전기적 신호가 기록장치(8)에 인가되어 프린트할 수 있게 된다.As time (t) elapses, the weight is applied to the powder collecting table (3) as the powder sinks, and the weight display appears numerically on the electronic scale (1), and the electrical weight corresponding to the weight output from the electronic scale (1) A signal is applied to the recording apparatus 8 to enable printing.
분체의 분산성이 양호하면 분체가 분체채취대(3)의 원반(3')에 서서히 가라앉아 분체채취대(3)의 무게 W(g)는 제4도의 (가) 곡선과 같이 완만하게 상승하는 반면에 분체의 나쁘면 분체가 응집된 덩어리들의 무게 때문에 빨리 가라앉게 되어 분체채취대(3)의 무게 W(g)는 제4도의 (나)와 같이 급속히 상승하게 된다.When the dispersibility of the powder is good, the powder gradually sinks to the disk 3 'of the powder collecting table 3, so that the weight W (g) of the powder collecting table 3 gradually rises as shown in the curve (a) of FIG. On the other hand, if the powder is bad, the powder is settled quickly due to the weight of the aggregated mass, so that the weight W (g) of the powder collecting table 3 rises rapidly as shown in (b) of FIG.
그리고 표면처리가 잘되어 있는 경우는 분체의 입자표면에 붙은 표면처리제의 영향으로 분산성이 좋아져서 역시 서서히 가라앉게 된다.If the surface treatment is well done, the dispersibility improves due to the influence of the surface treatment agent attached to the surface of the particles of the powder, and also gradually sinks.
결국, 측정후 프린트된 시간경과에 따른 분체채취대(3)의 무게 변화의 그래프(제4도)를 분석하면 분체의 분산성과 분산용액의 특성을 비교 검토할 수 있게 된다.As a result, by analyzing the graph (Fig. 4) of the weight change of the powder collecting table 3 with the printed time passage after the measurement, it is possible to compare and examine the dispersibility of the powder and the characteristics of the dispersion solution.
이상과 같이 본 고안에 의하면 종래의 눈대중에 의한 측정이 아니라 시각 변화에 따른 분체 침강상황을 기록 장치를 통해 무게변화 그래프의 정확한 데이터를 얻음으로서 객관적인 측정을 할 수가 있고, 측정 개시후 계속 지켜볼 필요가 없이 나중에라도 데이터를 확인할 수 있는 편의성이 얻어진다.As described above, according to the present invention, it is possible to measure objectively by obtaining accurate data of the weight change graph through the recording device, rather than the conventional eye mass measurement. The convenience of checking the data even later without is obtained.
