introduction

There are many types of existing vulcanizers, and their appearance and structure are different. With the continuous improvement of the level of vulcanization testing technology, the current standards have been At the same time, in order to be consistent with the ISO 6502 series of standards, it is necessary to revise the current standards and update the technical content. GB/T 9869 “Determination of vulcanization characteristics of rubber using vulcanizer” aims to provide guidance for the selection and use of vulcanizers. The test method for determining the vulcanization characteristics of rubber using a vulcanizer is intended to consist of three parts. --- Part 1.Introduction. The purpose is to provide a general introduction and guidance for the design and use of vulcanizers. --- Part 2.Disc oscillating rheometer. The purpose is to clarify the technical requirements that the disc oscillating rheometer must meet and specify the use of disc Method for determining the vulcanization characteristics of rubber using an oscillating vulcanizer. --- Part 3.Rotorless Rheometer. The purpose is to clarify the technical requirements that rotorless rheometer must meet, and to specify the use of rotorless rheometer. Method for determining the vulcanization characteristics of rubber compounds using a chemical analyzer.

For referenced documents without a date, only the latest version (including all amendments) applies to this document. This document. GB/T 9869.1-2025 Rubber vulcanizate for the determination of vulcanization characteristics Part 1.Introduction (GB/T 9869.1-2025, ISO 6502-1.2018, IDT) Note. GB/T 25269-2010 Guide to calibration of rubber testing equipment (ISO 18899.2004, IDT) 3 Terms and Definitions The terms and definitions defined in GB/T 9869.1-2025 apply to this document. 4 Principles 4.1 Place the rubber sample in a closed mold cavity with a specified initial pressure and maintained at the vulcanization temperature. The disk oscillates with a small oscillating amplitude. The disk oscillation causes shear strain on the sample. The torque of the disk oscillation depends on the stiffness of the rubber compound (shear Modulus). The torque is automatically recorded graphically as a function of time. 4.2 As the vulcanization progresses, the stiffness of the rubber specimen gradually increases. When the recorded torque rises to a stable value or a maximum value, the vulcanization is obtained. Curve (see GB/T 9869.1-2025). If the torque continues to rise, it is considered that vulcanization is not completed within the given time. The time values obtained depend on the test temperature and the properties of the rubber compound. 4.3 The parameter M = f(t) can be obtained from the recorded torque versus time vulcanization curve.
