As one of the important materials in the rubber industry, the quality and performance of low-compliance rubber directly affect the product quality and market competitiveness. Therefore, it is of great significance to study the detection method and analysis technology of low-cis rubber. This article will introduce several commonly used low-compliance rubber detection methods and analysis techniques.

The tensile test method is introduced. Tensile test method is a common low-compliance rubber testing method, by applying tensile force to the rubber sample, measuring its stress and strain, so as to obtain the mechanical properties of rubber parameters, such as tensile strength, elongation at break and so on. This method is simple and reliable, and is widely used in the quality control and research of rubber products.

The scanning electron microscopy analysis technique is introduced. Scanning electron microscopy microanalysis technology can be used to observe and analyze the microstructure of low-compliance rubber samples, revealing their surface morphology, fracture characteristics and heterogeneity distribution. This technology has the characteristics of high resolution and high sensitivity, which can provide important data support for the study of the structural properties of rubber materials.

The infrared spectrum analysis method is introduced. Infrared spectroscopy is a very effective method for low-compliance rubber detection. By measuring the absorption characteristics of rubber samples in the infrared band, the molecular structure can be qualitatively and quantitatively analyzed, and the functional groups and chemical bond types can be identified, which can provide technical support for the quality control and modification of rubber materials.

In addition to the methods and techniques described above, there are some other low-compliance rubber detection methods and analysis techniques that are also worthy of attention. For example, nuclear magnetic resonance (NMR) technology can obtain structural information of rubber molecules through the measurement of nuclear spins in rubber samples, and conduct a comprehensive analysis and evaluation of rubber properties.

Thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) are also commonly used for the detection and analysis of low-cis rubbers. DSC can study the thermodynamic properties of rubber materials, such as glass transition temperature, crystallization behavior, etc. TGA can analyze the thermal stability and thermal decomposition characteristics of rubber, and provide reference for engineering design and material selection.

The detection methods and analysis techniques of low-compliance rubber involve many fields, including mechanical performance testing, microstructure observation, molecular structure analysis and thermal performance evaluation. It is of great significance to select appropriate methods and technologies to improve the quality, performance and competitiveness of rubber products. It is hoped that the introduction of this paper can provide useful reference and guidance for related industries.
