Background
In recent years, the sealant industry in China is developed vigorously and widely applied to the industries of buildings, automobiles, rail transit, electronics and the like. Wherein, the plasticity value of the sealant is an important index for testing the elasticity of the sealant.
The national standard GB/T12828-2006 parallel plate method for measuring plasticity value and recovery value of crude rubber and unvulcanized rubber compound requires that the sample should not have air bubbles and has a volume of 2.00cm3±0.02cm3A cylinder of (16 mm diameter, 10mm height is suitable). The specimens can be prepared from whole or laminated green sheets of approximately 15mm thickness, with careful exclusion of air bubbles from the sheets. The sample can be cut from the rubber sample by two matched cutting knives or by a cutter with an inner diameter of about 16mmAnd (4) rotating a cutter to cut and prepare. If the sample density is known, the exact volume can be obtained by weighing. Three test specimens should be prepared, lightly sprinkled with talc powder, and then placed on a suitable holder to avoid deformation of the specimens prior to testing.
The sample cutting method proposed by the national standard can be operated for the sealant which is difficult to deform and adhere, but the sealant with large surface viscosity cannot be cut, is easy to deform, is difficult to obtain samples with consistent shapes, finally causes great deviation of measured values, and is difficult to obtain a unified conclusion.
