Description
Существующие методы испытани пленок св зующих материалов не дают достаточно надежных результатов.Existing methods for testing films of binder materials do not provide sufficiently reliable results.
Предлагаемый способ испытани пленок не имеет этих недостатков; Измерение нагрузки пленок осуществл ют при помощи нескольких калиброванных пластин, св занных с тензометрическим датчиком. Такой способ дает возможность определ ть прочностные характеристики пленок.The proposed method for testing films does not have these disadvantages; The load on the films is measured using several calibrated plates connected to a strain gauge. This method makes it possible to determine the strength characteristics of the films.
Дл испытани примен етс печь, перемещающа с по двум вертикальным стойкам и дающа возможность поддерживать температуру до 400°. В печи помещаютс два зажима. Нижний подвижной зажим соедин етс с черв чным винтом, а верхний - со стальной прогибающейс пластиной, укрепленной на верхней станине. С двух сторон на пластине наклеены тензометрические датчики с определенным сопротивлением. Прибор снабжен набором пластин, рассчитанных на различную нагрузку в зависимости от прочности испытуемого материала.For the test, an oven is used, moving in two vertical posts and maintaining the temperature up to 400 °. Two clamps are placed in the furnace. The lower movable clamp is connected with a screw screw, and the upper one with a steel bending plate fastened to the upper frame. Strain gauges with a certain resistance are pasted on the plate on both sides. The device is equipped with a set of plates, designed for different loads, depending on the strength of the test material.
Испытание заключаетс в том, что пленка, нанесенна на подложку (папиросную бумагу, фольгу и т. п.), закрепленна в двух зажимах при заданной температуре, раст гиваетс под действием равномерно возрастающего усили до наступлени разрыва. Предел прочности образца при разрыве выражаетс , величиной нагрузки при разрыве образца, отнесенной к единице первоначального поперечного сечени .The test is that the film deposited on the substrate (tissue paper, foil, etc.) fixed in two clips at a given temperature, is stretched under the action of a uniformly increasing force before the onset of rupture. The tensile strength of the specimen at break is expressed in terms of the load at break of the specimen, referred to the unit of the initial cross section.
