Introduction
GB/T 32679-2016 Ultra-high molecular weight polyethylene resin standard overview
GB/T 32679-2016 Ultra-high molecular weight polyethylene (PE-UHMW) resin is a national standard formulated for ultra-high molecular weight polyethylene materials, which stipulates its classification, naming, technical requirements, test methods and inspection rules. This standard is applicable to powdered PE-UHMW resin with a viscosity-average molecular weight ≥ 1 million, which is widely used in plastic products, films, fibers and other fields.
Comparison and analysis of standard frameworks
| Standard dimensions | GB/T 32679-2016 | Reference standard comparison |
|---|---|---|
| Classification and naming | Classified according to GB/T 21461.1-2008, providing a unified naming rule. | The sample preparation method is consistent with the international standard ISO 2818:1994. |
| Technical requirements | Including indicators such as appearance, viscosity, tensile stress, impact strength, etc., providing detailed technical parameter ranges. | It is consistent with GB/T 1632.3-2010 in terms of viscosity test method, and adds arbitration test conditions. |
| Test method | It specifies the determination methods of density, apparent density, tensile properties, etc., and adopts multiple standards for joint verification. | It is consistent with the international standard ISO 15527:2010 in terms of compression molded sheet testing. |
Standard implementation background and technological evolution
Background analysis:With the growing demand for high-performance plastics, ultra-high molecular weight polyethylene has been widely used in packaging, textiles and other fields due to its excellent wear resistance, impact resistance and chemical stability. The formulation of GB/T 32679-2016 fills the gap in domestic standards in this field and provides a unified technical basis for product quality.
Technological evolution:From the initial non-standardized production to the current standardized management, the standard of ultra-high molecular weight polyethylene resin has undergone a transformation from a single performance test to a comprehensive indicator system. This revision of the standard has introduced more internationally advanced test methods (such as ISO 15527:2010), reflecting technological progress in line with international standards.
Implementation suggestions
- Enterprise level:It is recommended that relevant production enterprises strictly follow the standards for raw material procurement and production process control, and establish a sound quality management system.
- Testing agency:Equipped with testing equipment that meets the requirements of the standard (such as capillary viscometer, impact testing machine, etc.) to ensure the accuracy and authority of the test data.
- Application areas:It is recommended to refer to standard technical indicators in the material selection and product design stages, and select appropriate grades and performance parameters based on actual application scenarios.
