GB/T 36020-2018 in English

National Standard of the People's Republic of China GB/T 36020—2018: Test Methods for Chemical Fiber Dipped Cord

Standard formulation background and technical evolution analysis

GB/T 36020-2018 was formulated to meet the needs of the development of the chemical fiber industry and standardize the quality inspection process of dipped cord. This standard has made a number of technical improvements on the basis of the original industry standard, including:

• Optimization of test methods: Two new methods for measuring adhesion strength and dry heat shrinkage have been added to ensure data accuracy.
• Unification of term definitions: The definitions of key terms such as "adhesive content" and "constant weight" have been clarified to avoid ambiguity.
• Improvement of equipment requirements: More accurate test instruments have been introduced, such as dry heat shrinkage testers and tensile testing machines.

Implementation Suggestions

To ensure the effective implementation of the standard, it is recommended to:

1. Train relevant personnel: Organize technical personnel to learn the content of the standard and master the new testing methods.
2. Update laboratory equipment: Configure testing instruments that meet the requirements, such as tensile testing machine and dry heat shrinkage tester.
3. Establish a quality control system: Develop testing process specifications to ensure that each batch of products meets the standard requirements.
4. Strengthen data management: Establish a test data management system for easy traceability and analysis.

Case Application

Take a chemical fiber enterprise as an example. When implementing the GB/T 36020-2018 standard, the product quality was significantly improved by introducing the adhesion strength test device and optimizing the vulcanization mold design. Specifically:

• Adhesion strength increased by about 15%
• Dry heat shrinkage was controlled within the standard range
• Product consistency was significantly enhanced

Conclusion

The implementation of GB/T 36020-2018 will promote technological progress in the chemical fiber industry and improve product quality. Through standardized testing processes and the application of advanced equipment, enterprises can meet market demand more efficiently.
