In the rubber manufacturing industry, vulcanizers play a vital role. As a professional equipment, vulcanizers use heat and pressure to make rubber and vulcanizing agents undergo cross-linking reactions, thereby improving the strength, elasticity and durability of rubber. This article will give you a detailed introduction to the working principle, types, and maintenance of vulcanizers.
Working principle of vulcanizer
The core working principle of vulcanizer is the vulcanization process, which is to cross-link the vulcanizer (such as sulfur) with the polymer chains in the rubber through thermal energy to form a three-dimensional network structure. This structure makes the rubber have excellent physical properties and chemical stability after vulcanization.
The vulcanization process is usually divided into two stages: heating and curing. In the heating stage, the vulcanizer heats the rubber and vulcanizer to a certain temperature through the heating plate, and this process is usually carried out between 150°C and 180°C. Heating causes the vulcanizer to react chemically with the rubber to form a cross-linked structure. In the curing stage, the rubber is maintained at high temperature and high pressure for a certain period of time to ensure that the cross-linking reaction is completely carried out, thereby improving the overall performance of the rubber.
Vulcanizers are mainly divided into the following types, each of which has its own unique application scenario
