Introduction

Most of my country's existing standards related to fluoropolymer dispersions, molding and extrusion materials were released in.1997, and they are all product standards. However, there is a lack of nomenclature system and basic classification standards for fluoropolymers. Some of the normative reference documents have been revised and changed. To contain For the healthy development of the fluoropolymer industry, better promotion and application, and domestic and foreign trade and technical exchanges, there is an urgent need to integrate various existing standards among industry enterprises. industry-implemented naming method, form standardized naming, unify product naming, and formulate fluoropolymer dispersions, molding and National standard for nomenclature and classification of extrusion materials. After studying the national and industry standards for plastic-fluoropolymer dispersions, molding and extrusion materials at home and abroad, a comparative analysis was conducted. ISO 20568.2017, GB/T 43084 aims to standardize the naming, classification and performance determination of fluoropolymer dispersions, molding and extrusion materials and sample preparation, which is intended to consist of two parts. ---Part 1.Nomenclature system and classification basics. The aim is to introduce a complete nomenclature system for fluoropolymers. ---Part 2.Sample preparation and performance determination. The purpose is to establish a standardized set of standard methods for test preparation and performance measurement. The two parts complement each other to form a complete standard system of fluoropolymers. The issuance and implementation of this document can standardize the sample preparation and performance measurement of fluoropolymer dispersions, molding and extrusion materials to meet customer needs. requirements to better promote trade, exchanges and technical cooperation. Plastic fluoropolymer dispersions, molding and extrusion materials Part 2.Sample preparation and performance determination Warning---Personnel using this document should be familiar with normal laboratory operating procedures. Each section of this document does not address all possible security issues. Users are responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated in relevant national regulations. This article The warnings in Part 6.1 and Appendix B identify specific hazards.
