T/JXSLXH 005-2024 Calcium zinc composite stabilizer

Scope

Main technical content: Polyvinyl chloride (PVC) is one of the five major general-purpose plastics. It has many excellent properties, but it degrades at high temperatures, so heat stabilizers need to be added during processing. Due to environmental protection requirements, PVC heat stabilizers containing heavy metals such as lead and cadmium salts are gradually being replaced by non-toxic stabilizers. Among them, calcium-zinc composite stabilizers are recognized as one of the best alternative products. Therefore, there is an urgent need to develop cost-effective domestic calcium-zinc composite stabilizers to replace imported similar products. There are no relevant national/industry standards for calcium-zinc composite stabilizers, and international standards are also in a blank stage. To standardize the orderly and healthy development of the industry and promote the improvement of the product quality of calcium-zinc composite stabilizers, it is proposed to formulate the "Group Standard for Calcium-Zinc Composite Stabilizers". By formulating the standard, we can fully incorporate the advanced technical achievements of today's new technologies and new processes, provide technical support for the promotion and application of calcium-zinc composite stabilizers, further promote the optimization and upgrading of the industry structure, and drive the rapid development of China's industry. It will guide and regulate the development of calcium-zinc composite stabilizer production technology, enhance the advancement, rationality, and applicability of the standard, and play a key supporting role in improving its technical level. This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage of calcium-zinc composite stabilizers. This standard applies to calcium-zinc composite stabilizers made from organic acid salts of calcium and zinc as the main raw materials, combined with other functional additives, and produced by
