Abstract
본 고안은 용기의 입구형태를 용기의 높이를 달리한 타원형으로 하고, 4∼5g의 일정한 시료를 담기에 적합한 원통형 용융흐름지수 측정용 계량용기에 관한 것이다.The present invention relates to a measuring vessel for measuring a cylindrical melt flow index suitable for holding a constant sample of 4 to 5g in the shape of the inlet of the container having a different height of the container.
Description
본 고안은 플라스틱의 용융흐름성 측정을 하는데 사용되는, 항상 일정한 량을 주입할 수 있고, 측정량을 임의로 조정할 수 있는 계량용기에 관한 것이다.The present invention relates to a measuring container which can always inject a constant amount, which can be used to measure the melt flowability of a plastic, and can arbitrarily adjust the measured amount.
수지를 원료로 플라스틱을 성형하기 전에 수지의 열적 흐름성(유동성)을 반드시 측정하여, 제품이 잘 만들어지도록 성형기계의 온도와 속도를 조절하여야 하는 바, 이러한 측정을 플라스틱의 용융흐름지수(Melt flow rate)를 측정한다고 하며 실험장비로는 용융흐름측정기(Melt flow indexer)를 이용하고 있다.Before molding plastic from resin as a raw material, it is necessary to measure the thermal flowability (fluidity) of the resin and to control the temperature and speed of the molding machine so that the product is made well. rate is measured and a melt flow indexer is used as an experimental device.
또한, 이러한 장비로 용융흐름지수를 측정할때는 일정온도(190℃ 또는 230℃)와 일정하중(2.16kg)하에서, 규정된 직경(2.09∼2.10mm)과 길이(7.98∼8.03mm)의 관을 통하여 10분간 흘러 나온 용융수지의 압출량을 측정한다.In addition, when measuring the melt flow index with such equipment, under a constant temperature (190 ℃ or 230 ℃) and a constant load (2.16 kg), through a tube of the specified diameter (2.09 ~ 2.10mm) and length (7.98 ~ 8.03mm) Measure the extrusion amount of the melted resin flowing for 10 minutes.
이때 압출량을 측정하기 위해서는 시료의 량을 4∼5g 정도 일정하게 측정기 내부에 넣고 실험을 하는데, 이때 사용되는 시료는 저울로 여러 종류의 시료를 그 때마다 계량하곤 하였다.At this time, in order to measure the amount of extrusion, the amount of the sample was put into the measuring device with a constant amount of about 4 to 5 g, and the experiment was used.
그러나, 국내·외 규정(KS, ASTM, JIS 규격)은 일정한 량만 규정되어 있기 때문에 각 회사별, 사람별로 감각적으로 시료량을 손, 수저, 종이, 용기등으로 주입하고 있으므로, 실험을 일관성이 없고 실험의 제한성이 늘 문제점으로 되었던 것이다. 따라서 본 고안은 이러한 문제점을 제거하기 위해서는 항상 일정한 시료의 량을 편리하고 쉽게 담아 넣을 수 있도록 하는 용융흐름지수 측정용 계량용기를 고안한 것이다.However, because domestic and foreign regulations (KS, ASTM, JIS standards) are prescribed only a certain amount, each company and each person is sensibly injecting the sample amount by hand, cutlery, paper, container, etc. The limitation of has always been a problem. Therefore, the present invention has devised a measuring container for measuring the melt flow index to always and conveniently contain a constant amount of sample in order to eliminate this problem.
도1은 본 고안의 계량용기의 사시도이다.1 is a perspective view of a measuring container of the present invention.
도2는 본 고안의 계량용기의 측면도이다.Figure 2 is a side view of the measuring container of the present invention.
따라서 본 고안은 용기의 입구형태를 용기의 높이를 달리한 타원형으로 하고, 4∼5g의 일정한 시료를 담기에 적합한 원통형 용융흐름지수 측정용 계량용기를 제공하는 것이다. 이때, 특히 측정용 용기의 재질이 드랄미늄인 것을 특징으로 한다.Therefore, the present invention is to make the inlet shape of the container to the oval with different height of the container, to provide a measuring container for measuring the cylindrical melt flow index suitable for holding a constant sample of 4-5g. In this case, in particular, the material of the measuring vessel is characterized in that the dralum.
이하 본 고안을 첨부된 도면에 의거 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 고안은 이러한 편리성과 정확성을 위해서, 용기입구 형태를 타원형으로 하였고, 4∼5g의 일정한 시료를 담을 수 있는 원통형 용기를 도 1과 같이 제작하였다. 또한 용기의 높이를 달리한 타원형으로 하여 시료 주입이 편리하도록 하였고, 측정량을 임의로 조절할 수 있도록 하였다. 도 2는 본 고안의 측면도인 바, 이러한 높이차를 나타낸다.The present invention for the convenience and accuracy, the inlet shape of the container was made of an oval, a cylindrical container that can hold a constant sample of 4 ~ 5g was produced as shown in FIG. In addition, the height of the container was made of an elliptical shape for convenient sample injection, and the amount of measurement could be arbitrarily adjusted. Figure 2 is a side view of the present invention, showing the height difference.
한편, 계량용기의 재질로는 실험 온도가 190℃, 230℃ 이므로 용기의 재질은 열에 강하고, 시용하기에 가벼운 것으로 사용하면 되는 바, 일반적으로 드랄미늄으로 알려진 알루미늄 합금강 또는 알루미늄으로 제작하는 것이 바람직하다.On the other hand, the material of the measuring container is 190 ℃, 230 ℃ because the material of the container is resistant to heat and light enough to be used, it is preferable to make the aluminum alloy steel or aluminum commonly known as dralum. .
따라서 본 고안의 효과는 항상 일정한 시료의 량을 편리하고 쉽게 담아 넣을 수 있도록 하는 용융흐름지수 측정용 계량용기를 제공하게 된 것이다.Therefore, the effect of the present invention is to provide a measuring container for measuring the melt flow index to always conveniently and easily hold a constant amount of sample.
