Description

Изобретение относитс  к приборам дл  определени  раст жимости и прочности на разрыв нленк1и.The invention relates to devices for determining the tensile strength and tensile strength of a film.

Известен прибор аналогичного назначени , содержащий штатив со шкалой, зажим дл  испытуемого образца пленки и рабоч;ий орган с грузом.A device of similar purpose is known, comprising a tripod with a scale, a clamp for a film test sample and a working body with a load.

Предлагаемый прибор в отличие от известных позвол ет осуш;ествить анализ пленки клейковины с предварительным ее формированием .The proposed device, unlike the known ones, allows to dry the analysis of the gluten film with its preliminary formation.

Достигаетс  это тем, что зажим представл ет собой цилиндр с наружной кольцевой проточкой и отверстием в боковой поверхности дл  выхода воздуха, а рабочий орган выполней в виде стержн  с усеченным шаром на конце.This is achieved by the fact that the clamp is a cylinder with an external annular groove and a hole in the side surface for air to escape, and the tool is made in the form of a rod with a truncated ball at the end.

На фиг. 1 схематически изображен предлагаемый прибор, общий ВИД; на фиг. 2- зажим.FIG. 1 schematically shows the proposed device, the overall appearance; in fig. 2- clamp.

Прибор дл  определени  раст жимости и прочности на разрыв пленки содерж1ит щтатив / со Щ|калой; зажим дл  испытуемого образца пленки, представл ющий собой цилиндр 2 с наружной кольцевой проточкой 3 и отверстием 4 в боковой поверхности дл  выхода воздуха; и рабочий орган, выполненный в виде стержн  5 с усеченным щаром 6 на конце.A device for determining the tensile strength and tensile strength of a film contains a material / s / y; a clamp for the test sample of the film, which is a cylinder 2 with an outer annular groove 3 and a hole 4 in the side surface for air to escape; and the working body made in the form of a rod 5 with a truncated ball 6 at the end.

Прибор работает следующим образом.The device works as follows.

Клейковину нат пивают на цилиндр 2, образу  пленку, и закрепл ют в проточке 3 боковой поверхности. Затем подвод т рабочий орган с усеченным концом щара 6 к поверхности пленк1и клейковины и, накладыва  постепемно груз на площадку 7, определ ют раст жимость, при этом замечают по шкале величину раст гивани  тонкой пленки клейковины в миллимет/рах (на сколько миллиметров опустилс  рабочий орган до момента разрыва пленк-и клейковины) и величину конечного груза.Gluten is drawn onto cylinder 2 to form a film and secured in the groove 3 of the side surface. Then, the working body with the truncated end of the shtick 6 is brought to the surface of the gluten film and, gradually putting a load on the platform 7, the extensibility is determined, and the stretching of the thin film of gluten is noted on a scale until the rupture of the film and gluten) and the value of the final load.

При м е р. На приборе определ ют клейковину , котора  имеет показатель качества клейковины, определенной на пластометре ПЛ-2,7,1 сек. |При проведени  определени  на приборе груз накладывают через каждые 10 сек. Провод т два повторных определени .An example. The device determines the gluten, which has a quality indicator of gluten, determined on the PL-2 plastometer. When determining on a device, a load is applied every 10 seconds. Two repeated determinations are made.

Предмет изобретени Subject invention

При1бор дл  определени  раст жимости и прочности иа разрыв пленк1и, содержащийWhen used to determine the extensibility and strength of a film break, it contains

штатив со шкалой, зажим дл  испытуемого образца пленк и и. рабочий орган с грузом, отличающийс  тем, что, с целью обеспечени  возможности анализа пленки клейковины и предварительного ее формировани , зажимa tripod with a scale, a clip for the test sample film and and. working body with a load, characterized in that, in order to enable analysis of the gluten film and its prior formation, the clamp

представл ет собой цилиндр с наружной кольцевой проточкой и отверстием дл  выхода воздуха, а рабочий орган выполнен в виде стержн  с усеченным шаром на конце.is a cylinder with an external annular groove and an air outlet, and the working body is made in the form of a rod with a truncated ball at the end.
