Description
Technical Field
The utility model relates to a vicat softening temperature test equipment field especially relates to a tubular product heat altered shape vicat testing machine.
Background
The heat resistance of a polymer, generally refers to its ability to retain its physical and mechanical properties when the temperature is increased. The heat resistance temperature of a polymeric material is the temperature at which it reaches a certain set value under a certain load. The temperature at which the deformation occurs is generally referred to as the softening point TS of the plastic. Because of the different test methods used, each with its parameters selected for specification, the physical meaning of the softening point is not as well defined as the glass transition temperature. The heat resistance of the plastic is tested by a common Vicat heat-resistant and Martin heat-resistant and thermal deformation temperature test method. The test results of the different methods have no quantitative relationship with each other, and they can be used for relative comparison of different plastics. The Vicat softening point is measured by measuring the temperature of a thermoplastic plastic sample in a specific liquid heat transfer medium under a certain load and at a certain constant temperature2The temperature at which the needle is pressed in 1 mm. The process is only applicable to most thermoplastics. The experimentally determined Vicat softening point is suitable for controlling quality and is used as an index for identifying the thermal properties of new varieties.
When a Vicat softening temperature tester is required to test the Vicat softening temperature of the pipe, firstly, a test sample is required to be manufactured, and for the pipe with the wall thickness smaller than 2.4mm, an arc-shaped sample obtained by cutting the pipe needs to be heated and flattened to obtain a flat plate sample. During the test, the concave surface of the arc-shaped sample is upwards arranged on the flat plate sample, and no gap is formed between the concave surface and the flat plate sample. The sample arranged in the double layers is not easy to fix, and once the sample moves in the test, the test result is invalid; in the test process, in order to keep the temperature of each part of the liquid heat-conducting medium (such as methyl silicone oil) consistent, stirring is required, so that the liquid heat-conducting medium flows continuously, and if a sample is influenced by rising liquid flow, the test result is inaccurate; the tucking needle should act on the minimum of arc sample concave surface to ensure that there is not the clearance between arc sample and the dull and stereotyped sample, but the arc sample is difficult to aim at the tucking needle when setting up, needs to adjust repeatedly, and the operation is inconvenient.
