Description

Известные приборы дл  определени  набухаемостй и растворимости гелей и тому подобных тел в жидкост х , включающие набухометр и вискозиметр, не обеспечивают одновременного определени  набухаемостй и растворимости, например , образца гел .The known devices for determining the swelling capacity and solubility of gels and the like in liquids, including a swelling meter and a viscometer, do not provide simultaneous determination of the swelling capacity and solubility of, for example, a gel sample.

В описываемом приборе этот недостаток устранен. Прибор выполнен в вил.е трех стекл нных резервуаров:-f , одного нижнего и двух, расположенных под ним, верхних, соединенных с нижним резервуаром двум  микропипетками, из которых одна снабжена капилл ром.In the described device, this disadvantage is eliminated. The device is made in the forks of three glass tanks: -f, one bottom and two located under it, the top, connected to the bottom tank by two micropipettes, one of which is equipped with a capillary.

На чертеже изображен обш,ий вид прибора.The drawing shows the general view of the device.

Прибор состоит из двух параллельных микропипеток 1 и 2, резервуаров 3 и 4, капилл ра 5 и резервуара 6 с пришлифованной пробкой 7, снабженной крючком 8, к которому прикрепл етс  испытываемый материал.The device consists of two parallel micropipettes 1 and 2, reservoirs 3 and 4, a capillary 5 and a reservoir 6 with ground up plug 7 fitted with a hook 8 to which the test material is attached.

Действует прибор следующим образом . При вертикальном положении он заполн етс  жидкостью до средних делений микропипеток. Испытываемый материал крепитс  кThe device operates as follows. In the vertical position, it is filled with liquid to the middle divisions of micropipettes. The test material is attached to

крючку 8 и производитс  определение „нулевой точки, т. е. отсчитываетс  количество  сидкости в микропипетках и в зкость ее после смачивани  стенок сосуда и образца до начала набухани . Затем прибор устанавливаетс  в горизонтальное положение и выдерживаетс  до тех пор, пока жидкость не заполнит резервуары 4 и 6. Таким образом, дают образцу набухнуть. Через определенные, требуемые опыто.м, промежутки времени прибор устанавливаетс  снова в вертикальное положение, при этом врем  истечени  жидкости из резервуара 6 между метками 9 и 10 измер ют секундомером. Изменение объема отмечают по изменению уровн  в микропипетках 1 и 2.the hook 8 is used to determine the zero point, i.e., the amount of sidkosti in the micropipettes and its viscosity after wetting the walls of the vessel and the sample before the swelling begins. The device is then placed in a horizontal position and maintained until the fluid fills tanks 4 and 6. Thus, the sample is allowed to swell. After a certain time required by the experiment, the device is set in the vertical position again, and the time of the outflow of fluid from the reservoir 6 between marks 9 and 10 is measured by a stopwatch. The change in volume is noted by the change in level in micropipettes 1 and 2.

По скорости перетекани  жидкости через капилл р (при вертикальном положении прибора) определ етс  изменение в зкости жидкости по мере растворени  материала образца в жидкости.The rate of flow of fluid through the capillary (with the instrument in a vertical position) determines the change in the viscosity of the fluid as the sample material dissolves in the fluid.

По уменьшению объема жидкости , измер емого по делени м микропипетки , определ етс  степень набухани  испытываемого материала.By reducing the volume of fluid measured by the divisions of the micropipette, the degree of swelling of the test material is determined.

Посто нство температуры обеспечиваетс  пропусканием проточной воды из термостата через сосуд 11, в котором прибор укреплен при помощи пробок 12 и 13 и прокладки 14. Контроль температуры осуществл етс  нормальным термометром , вставл емым в отверстие 15. Предмет изобретени The temperature is maintained by passing the flowing water from the thermostat through the vessel 11, in which the device is fixed with the help of plugs 12 and 13 and the gasket 14. The temperature is controlled by a normal thermometer inserted into the hole 15. The subject matter

Прибор дл  определени  набухаемрсти и растворимости гелей и тому подобных тел в жидкост х,A device for determining the swelling and solubility of gels and the like in liquids,
