3 Definitions
This standard adopts the following definitions.
3.1 Heated vulcanized rubber lining
The unvulcanized lining is pasted on the lined equipment with a rubber sheet with an adhesive, and the lining is vulcanized by heating (high-pressure steam, normal-pressure steam, hot water, hot air). The vulcanized rubber sheet is divided into hard rubber, semi-hard rubber and soft rubber according to its hardness. 3.2 Naturally vulcanized rubber lining
The lining is formed by attaching the unvulcanized lining to the lined equipment with a rubber sheet using an adhesive and completing the vulcanization process at room temperature. 3.3 Prevulcanized rubber lining
The lining is formed by attaching the prevulcanized lining to the lined equipment with a rubber sheet using an adhesive. 4 Classification
4.1 Linings are classified by vulcanization method as shown in Table 1. Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on July 13, 2001 180
Implemented on February 1, 2002
The classification of rubber types for linings is shown in Table 2.
