This standard specifies the basic process and technical requirements for the production of natural raw rubber—tire-specific rubber. This standard is applicable to the process of producing tire-specific rubber using fresh latex coagulum, field coagulum, rubber threads, and scrap rubber as raw materials, mixed approximately in the proportion of 1 part fresh latex coagulum, 4 parts field coagulum, 3 parts rubber threads, and 1 part (or less than 1 part) scrap rubber.
本标准规定了天然生胶— 轮胎专用胶在生产过程中的基本工艺及技术要求。 本标准适用于用鲜胶乳凝块、胶园凝块、胶线、泥胶为原料，约按鲜胶乳凝块1份、胶园凝块4份、胶 线3份、泥胶1份(或1份以下)的比例混合生产轮胎专用胶的工艺。
📝 Foreword / 前言 ai_extracted
This standard is formulated based on the production conditions of tyre rubber in China. Tyre rubber is a new variety of natural raw rubber, which passed technical appraisal in 1989. This tyre rubber is typically blended in the following proportions: 1 part fresh latex coagulum, 4 parts field coagulum, 3 parts cup lump, and 1 part or less of tree scrap. The process encompasses the production procedures for latex standard rubber and scrap standard rubber, and the quality standards adopt the quality indicators for Grade 10 rubber as specified in GB 8081-1987 "Raw Natural Rubber - Standard Rubber Specifications". This standard was proposed by the Ministry of Agriculture of the People's Republic of China. This standard is under the jurisdiction of the Natural Rubber Subcommittee of the National Technical Committee on Rubber and Rubber Products Standardization. This standard was drafted by the South China Tropical Agricultural Products Processing and Design Research Institute. The main drafters of this standard are: Zhang Beilong, Wang Ailing. This standard is entrusted to the Natural Rubber Subcommittee of the National Technical Committee on Rubber and Rubber Products Standardization for interpretation.
