Description

При определении иззестнымл способами поверхностной влажности различных материалов путем взвешивани  навески в воздушной среде, а затем в смешивающейс  с водой жидкости необходимо знать удельный вес материала н влажность его - что не всегда возможно.In determining the surface moisture of various materials by means of weighing the sample in air, and then in a fluid that is miscible with water, it is necessary to know the specific weight of the material and its moisture content - which is not always possible.

Предлагаемый способ позвол ет устранить необходимость определени  удельного веса испытуемого материала. Это достигаетс  тем, что производ т третье взвек1ивание {аБеск;-; в жидкости, имеющей отличный от первой удельный вес. Количество поверхностной влаги определ ют по формуле:The proposed method eliminates the need to determine the specific gravity of the test material. This is achieved in that the third injection is performed {abesk; -; in a liquid that has a different weight from the first. The amount of surface moisture is determined by the formula:

/7e: VL ILI1T2 J,/ 7e: VL ILI1T2 J,

где: JlJB-поверхностна  влажность,where: JlJB is surface moisture,

Р - вес пробы в воздухе,R - the weight of the sample in the air,

ве-ч. пробы 3 первой жидкости, Р2 - вес пробы во второй жидкости, all samples 3 of the first liquid, P2 - the weight of the sample in the second liquid,

Vi- удельный вес первой жидкости.Vii is the specific gravity of the first fluid.

Та-удельный вес второй жидкости.The specific gravity of the second fluid.

Сущность способа заключаетс  в том, что проба испытуемого .материала , предварительно взвешенна  в возду.че, помещаетс  в решетчатый контейнер и взвещиваетс  последовательно при опзскании ее в сосуды с двум  ЖИДКОСТЯМИ, имеющими различный уделыгый вес, который известен. Эти жидкости должны обладать свойством смешиватьс  с водой., что необходимо дл  того, чтобы поверхн.остна  влага переходила в объем этих жидкостей при погружении в них навески испытуемого материала и не оказывала вли ни  на результаты взвешивани .The essence of the method is that a sample of the test material, previously weighed in air, is placed in a trellis container and vozveshatsya consistently when it is found in vessels with two LIQUIDS, having different weight, which is known. These liquids must have the property of being mixed with water, which is necessary in order for the surface moisture to pass into the volume of these liquids when the sample of the test material is immersed in them and does not affect the weighing results.

Влажность навески испытуемого материала с кубических сантиметрах (или и граммах) подсчитыБаетс  по припеденной выше формуле.The moisture content of the test material per cubic centimeters (or grams) was calculated using the formula above.

В качестве одиой из жидкостей удобно пр1В еи ть дистиллированную иоду, удельный вес которой равен единице, а в качестве другой может быть применен раствор сахара в воде. Это тем более удобно, что заранее подготовленный раствор сахара известной концентрации может быть добавлен в мерный стакан с водой, в котором производилось первое взвешивание, без извлечени  контейнера с пробой материала из стакана.As one of the liquids, it is convenient to use distilled iodine, whose specific gravity is one, and the other can be a solution of sugar in water. This is all the more convenient since a previously prepared sugar solution of a known concentration can be added to the measuring cup with water, in which the first weighing was performed, without removing the container with the sample of material from the glass.

В случае при.менени  в качестве одной из Жидкостей дистиллированной воды формула дл  определении поверхностной влажности принимает вид:In the case of priming as one of distilled water liquids, the formula for determining the surface moisture is:

/75(Я-А) ,/ 75 (I-A)

где Тж - дельныи вес жидкости.where Tj - fluid weight.

Предмет изобретени Subject invention

Способ определени  поверхностной влажности различных материалов взвешиванием навески в воздушной среде, а затем в смешивающейс  с водой жидкости, о тл н ч а ю ш, и йс   тем, что, с целью устранени  необходимости опредачени  удельного веса испытуемого .материала, лроизвод т третье взвешивание навески в жидкости, имеюш,ей отличный от-первой удельный вес. Количество поверхностной влаги определ ют по формуле:The method of determining the surface moisture of various materials by weighing the sample in an air medium, and then in a water-miscible liquid, that is, in order to eliminate the need to determine the specific weight of the test material, the third weighing of the sample in a liquid, I have, it has a different weight from the first. The amount of surface moisture is determined by the formula:

где: ПВ - поверхностна  влажность, Р - вес пробы в воздухе, пробы в первой жидкости, 2 - вес пробы во второй жидкости, Ti - удельНый вес первой жидкости, удельный вес второй жидкости.where: PV is surface moisture, P is the sample weight in air, samples in the first liquid, 2 is the sample weight in the second liquid, Ti is the specific weight of the first liquid, and the specific gravity of the second liquid.
