Description
Изобретение отнооито к способам определени влажностл не растворимых в воде материалов, например, песка кварцевого.The invention relates to methods for determining moisture content of water-insoluble materials, for example, quartz sand.
Влажность материалов определ ют обычно путем взвешивани 1фобы до высушивани и после высушивагаи и процент влажности вычисл ют по известной формуле. Этот способ занимает много времени, так как процесс высушивани пробы до посто нного веса довольно длительный .The moisture content of the materials is usually determined by weighing the 1phobia before drying and after drying, and the percentage of moisture is calculated by the known formula. This method takes a long time, since the process of drying the sample to a constant weight is rather long.
Олисываемый способ по сравнению с общеприн тым .имеет то преимущество , что ускор ет испытание за счет исключени высушивани пробы.The process to be polished compared to the conventional method has the advantage of speeding up the test by eliminating the drying of the sample.
Его особенность заключаетс в том, что пробу взвешивают сначала в воздухе, а затем погруженной в воду и вычисл ют влажность по формуле, приведенной в предмете изобретени .Its feature is that the sample is weighed first in air and then submerged in water and the humidity is calculated according to the formula in the subject invention.
Способ основан на законе физики, согласно которому тело, погруженное в жидкость, тер ет в своем весе столько, сколько весит вытесненна им жидкость. Исход из этого закона, вода, составл юш,а влажность пробы, становитс в воде невесомой.The method is based on the law of physics, according to which a body immersed in a liquid loses in its weight as much as the liquid it displaces. Based on this law, water was used and the humidity of the sample became weightless in the water.
Берут тару, например, в форме стаканчика .и взвешивают ее на технических весах оначала в воздухе, а потом погруженной в воду. Дл лучшего погру кепи тару предварительно наполн ют водой. Оба веса запнг:ывают. Взвешивание тары производитс одпн раз на неопределенно длительный период времени. Затем в тару кладут пробу и взвешивают ее вместе с тарой один раз в воздухе и один раз в воде при по, ее погружении.They take tare, for example, in the form of a cup. And weigh it on a technical scale, first in air, and then submerged in water. To better immerse the kepi, the tare is pre-filled with water. Both zapng weights: The tare is weighed once for an indefinitely long period of time. Then a sample is put into the container and weighed it together with the container once in the air and once in the water while in, it is immersed.
Вычита из полученных весов заранее найденные весы тары, получают веса пробы без тары в воздухе и в воде.Subtracting the previously found tare scales from the obtained weights, we get the sample weights without the container in the air and in the water.
Процент влажности вычисл ют по формуле, приведенной в пред Nl 11786SThe percentage of moisture is calculated by the formula given in prev Nl 11786S
мете изобретенИЯ. Вход щи в формулу удельный вес испытуемого материала наход т заранее дл всей партии.Mete Invention. Entering into the formula the specific gravity of the test material is found in advance for the entire batch.
Предмет изобретени Subject invention
Способ определени влажности, например, песка кварцевого, о гл и чающийс тем, что, с целью ускорени исьытаии без высушивани пробы, последнюю взвеимвают сначала Б воздухе, а потом погруженной в воду и определ ют влажность по форму.чс:The method of determining the moisture content, for example, quartz sand, is mainly based on the fact that the latter is first taken up with air and then immersed in water and the humidity is determined by the form.ph:
