Plastic tensile property test

As one of the key projects of plastic testing, tensile property has many hazards for the main performance of plastic quality. The key test index values related to tensile properties include compressive strength, shear strength, ring compression strength, tensile strength, yield strength, elongation at break, tensile strength and elastic mold. The key of tensile property is to test the static data of plastic raw materials according to the tensile testing machine, and then comment on the main performance of tensile structure in specific production and manufacturing applications.

1、 Plastic tensile property testing category
Plastic film, plastic pipe fittings, plastic decorative building materials, plastic utensils, plastic casings, plastic small toys, cable insulating sleeves, insulating layer plastics, plastic pvc profiles, plastic decorations, etc.
2、 Basic principle of plastic tensile property testing
Under the specific test temperature, environmental humidity and tensile rate, the tensile load is increased according to the vertical direction of the plastic test object to make the test object deformed until the raw material cracks. Record the change of large load and the corresponding distance between lines when the test object is invalid. On the tensile testing machine with a microcontroller, only the size of the test object and other relevant data and regulations need to be keyed in. During the whole stretching process, the sensor will transmit the force value to the computer. The computer automatically saves the stretch values. The whole process of geostress – strain stress. Record and print the geostress strain stress curve and data test according to the copier.
3、 Elements of tensile test of hazardous plastics
The tensile property test must be carried out with rigorous detection and determination, which naturally causes unavoidable deviation in the whole process of detection. This essentially includes the transformation of plastic composition, the size and distribution of relative molecular weight measurement, the evaluation of molecular formula, the trend of molecular structure, internal defects and other factors. Externally, the most likely influencing factors are the selection of test instruments and equipment, the preparation and solution of test pieces, the natural environment of the test, the quality of testing staff, the operation process, and the method of data processing.
