Description

Известно применение электрического способа дл  определени  влажности твердых и сыпзчих материалов .It is known to use an electrical method for determining the moisture content of solid and loose materials.

Известны также электрические измерительные устройства дл  онределени  коицентрации растворов и гигроскопичности формовочных cMeceii, снабженные многими, соединенными с электрическими измерительными приборами, контактами, располол енными на разных уровн х внутри сосудов с исследуемыми веществами или непосредственно на самом веществе.Also known are electrical measuring devices for determining the concentration of solutions and the hygroscopicity of molding cMeceii, equipped with many contacts connected to electrical measuring devices located at different levels inside the vessels with the test substances or directly on the substance itself.

Отличительной особенностью описываемого способа  вл етс  то, что, с Целью ускорепп  процесса определени  гигроскоиичности испытуемого образца смеси, последний непосредственно вводитс  нижней частью в соприкосповение с водой. После этого засекают врем  начала контакта образца с водой и фиксируют скорость подъема воды в образце при поочередном замыкапии электрических контактов.A distinctive feature of the described method is that, with the Purpose of accelerating the process of determining the hygroscopicity of the test specimen of the mixture, the latter is directly introduced by the lower part into contact with water. After that, mark the time of the beginning of the contact of the sample with water and record the rate of rise of water in the sample with alternate closure of electrical contacts.

11а чертеже изображена схема устройства.11a is a schematic drawing of the device.

Устройство, осуществл ющее данный сиособ, состоит из сосуда / с водой 1 сгекл нно| 1 подставки 2, покрытой тканью 3, 1гапример, марлей, концы которой погружены в воду.The device implementing this method consists of a vessel / with water 1 bleached | 1 stand 2, covered with a cloth 3, 1 example, gauze, the ends of which are immersed in water.

На подставке 2 }ттановлены две колодки 4, между которыми в вертикальном положении .ладываетс  образец 5j состо нии из испытуемои формовочной смеси.On the stand 2}, two pads 4 are inserted, between which a sample of the 5j state of the test sand is placed in a vertical position.

На одиоГ нз ко.юдок 4 на pa.inoii высоте от подставки 2 расноложсны контакты 6. Каждый контакт одним концом присоединен к электрическому измерительному прибору 7, например , гальванометру, а другим концом непосредственно соединен с испытуемым образцом.On odioG nz ko.udok 4 at pa.inoii height from stand 2, contacts 6 are located. Each contact is connected at one end to an electrical measuring device 7, for example, a galvanometer, and the other end is directly connected to the test specimen.

Электрические измерительиые приборы 7 соединены через источник 8 электротока с водой.Electrical measuring devices 7 are connected via a source of 8 electric current with water.

Испытание образца па гигроскопичность происходит следуюпцм оПразом .The test sample hygroscopic pas occurs nextpopm.

При установке испытуемого обрп: ца .5 на подставку 2 с HacbHiuMiiioii водой марлей засекают на секундомере врем  начала контакта inoKiioit части образца с водой. Затем фиксируют скорость подъема воды в образце . Вода, поднима сь по образцу, замыкает цепь через контакты 6. Момент замыкани  цепи отмечаетс  электрическими пзмернтельцы.ми приборами 7. When installing the tested specimen: .5 on a stand 2 with HacbHiuMiiioii water with gauze, mark the stopwatch time of the inoKiioit contact of the sample with water on a stopwatch. Then fix the rate of rise of water in the sample. Water, rising over the model, closes the circuit through the contacts 6. The moment of the circuit closure is indicated by electrical devices with their devices 7.

Такой способ позвол ет ni.icrpo определ ть гпгроскоппчпость формовочных cMeccif при большо простоте ос)11,естплепп  и зпачптольпом ускорении работы по подбору формовочпых смесей с требуемой гигроскопичностью .This method allows the ni.icrpo to determine the molding capacity of the molding cMeccif with greater simplicity of the OS) 11, smoothness and acceleration of the work on the selection of mold mixes with the required hygroscopicity.
