PVC foam board, also known as Chevron board and Andy board, is a plastic board made of polyvinyl chloride (Polyvinyl chloride) as the main raw material, adding stabilizers and foaming agents and other auxiliary materials, after mixing, extruding, and foaming. With various processing properties of wood, it is an ideal substitute for wood, aluminum and composite boards. In addition, due to its good thermal insulation, heat preservation, sound insulation, light load-bearing properties, it is widely used in decoration and decoration, commercial advertising, construction, transportation, pharmaceutical and chemical anti-corrosion, sports equipment, moisture-proof and water-resistant materials and other industries and fields.
With the gradual deepening of the impact of lightweight technology, the demand for PVC foam board has grown rapidly. However, the increase in market demand has brought about the problem that the quality of PVC foam board products is uneven, causing many unnecessary trade disputes and Adverse consequences. Therefore, whether it is a manufacturer, purchaser or user of PVC foam board, it is necessary to pay attention to and understand the relevant knowledge of PVC foam board product testing.
The main inspection items of PVC foam board include appearance size inspection, water absorption performance and closed cell volume inspection and mechanical performance inspection. Taking mechanical properties as an example, due to the wide range of use of PVC foam board, it will encounter a variety of working conditions during application. Typical stresses such as compression, shearing, and tension. Therefore, the destructive index of PVC foam board It is very important, such as compressive strength, shear strength, shear elongation at break, tensile strength, etc. in addition, to ensure the service life of PVC foam board, compression modulus, tensile modulus, shear modulus and other material deformation Indicators are also important test indicators.
WDW electronic universal testing machine is suitable for various tensile compression, bending and shear tests of PVC foam board. Various experimental data processing software and test aids can be customized according to the standards provided by customers.
