Description
Прибор Предназначен дл .ко-нтрол газопроницаемости фор мовочных и других пористых сМбсей, причем,The device is intended for the gas permeability of forming and other porous materials, and
0газопроницаемости смеси суд т по способности этой смеси смачиватьс жидкостью.The gas permeability of the mixture is judged by the ability of this mixture to be wetted with liquid.
Известно, что существующие способы определени газопроницаемости смеси основаны на пропускании через испытуемый стандартного размера образец определенного количеств1а воздуха при помощи весьма сложных приборов.It is known that the existing methods for determining the gas permeability of a mixture are based on passing a certain amount of air through a standard-sized sample under test using very sophisticated instruments.
Предлагаемый прибор отличаетс от уже известных устройств подобного рода тем, что в результате определвни1 газопроницаемости по водопроницаемости испытани производ тс ,в услови х норм ального атмосферного дaвлeни без использовани энергии сжатого воздуха или вакуума. Это дает возможностьThe proposed device differs from the already known devices of this kind in that, as a result of the determination of gas permeability according to water permeability, tests are performed under normal atmospheric conditions without using the energy of compressed air or vacuum. This makes it possible
упростить и ускорить процесс И(СПЫтани при обеспечении необходимой точности.simplify and speed up the process AND (SPYTANI while ensuring the necessary accuracy.
На схематическом чертеже изображен прибор длi определени пористости формовочных и других смесей.The schematic drawing shows a device for determining the porosity of molding and other mixtures.
Прибор состоит иЗ двух сквозных градуированных стекл нных трубокThe device consists of two through graduated glass tubes.
1и 5. Трубки устанавливают вертикально одну над другой.1 and 5. Tubes are installed vertically one above the other.
В трубку 1 помещают ирпытуемую формовочную смесь 2, под трубку подкладывают фильтровальную бумагу . Трубку 3 заполн ют водой ИЛ|И иной рабочей жидкостью, определенное количество которой при помощи крана 4 наливают в трубку / поверх испытуемой Смеси.The molding molding mixture 2 is placed into the tube 1, filter paper is placed under the tube. The tube 3 is filled with water IL | And another working fluid, a certain amount of which is poured into the tube / on top of the tested mixture using a crane 4.
Жидкость проникает чер-ез поры омеси вниз, вытесн воздух через открытый конец трубки.The liquid penetrates through the pores of the omega down, displacing the air through the open end of the tube.
Длительность проникновени воды через образец отсчитываетс секундомером; момент проникновени определ етс по фильтровальной бумаге,.The duration of the penetration of water through the sample is counted by a stopwatch; the moment of penetration is determined by filter paper.
Газопроницаемость смеси определ етс по скорости проникновени жидкости через образец определенных размеров и плотности.The gas permeability of the mixture is determined by the rate of penetration of the liquid through the sample of a certain size and density.
За исходную пористости формовочных смесей принилгаетс пористость сухого люберецкого песка № 50/100. Врем проникновени воды через столбик этого песка высотой в 28 .«.мидиаметром 9,5 мм ра-вно п ти секундам.For the initial porosity of the molding sands, the porosity of dry Lyubertsy sand No. 50/100 is applied. The time of penetration of water through a column of this sand with a height of 28 ".". With a midiometer of 9.5 mm is five seconds.
