    Vulcanized ShoesInterpretationAnalysis

    < p > sulphide < a href= "http://www.91se91.com/news/index_x.asp" > sole > /a > vulcanized rubber. After vulcanizing, rubber products are not easy to be aged, cracked, elastic and heat-resistant. Nowadays, rubber products are basically made of rubber, also known as rubber or rubber.

    < /p >


    < p > vulcanized shoes are sports leisure shoes made of "vulcanizing method" made of soles and uppers, which are joined by sulphur. In order to strengthen elasticity and hardness, the vulcanized shoes are treated with rubber and sulphur treated on the sole of shoes to increase the elasticity and hardness of rubber shoes. After vulcanizing, it is not necessarily just canvas shoes. < a href= "http://www.91se91.com/news/index_x.asp" > sulphide < /a > treatment is first invented by PUMA in 1960.

    < p > < strong > advantages of vulcanized shoes: < /strong > < /p >


    < p > fashion, good-looking, with Jeans Classic; dirty is relatively good, and the price is moderate; < /p >


    < p > disadvantages: the pattern is not very large, the skin is wrinkled, it is ugly, can not do vigorous exercise, and the shoe is still a little heavy.

    < /p >


    < p > the word "vulcanization" has its historic significance. Since the original natural rubber product was named as crosslinking agent with sulfur as the crosslinking agent, with the development of the rubber industry, a variety of non sulfur crosslinking agents can now be used for cross-linking.

    Therefore, the more scientific significance of sulfidation should be "crosslinking" or "bridging", that is, the process of linear polymer formation through cross-linking.

    Physically, it is the process of pforming plastic rubber into elastic rubber or hard rubber.

    The meaning of "vulcanization" includes not only the actual cross-linking process, but also the method of cross-linking.

    < /p >


    < p > through the measurement of the elongation strength of rubber material (or vulcanizer), it can be seen that the whole vulcanization process can be divided into four stages: vulcanization induction, pre sulphur, positive vulcanization and sulphur (for natural rubber).

    < /p >


    During the vulcanization induction period (scorching time), the crosslinking has not yet started, and the P has good fluidity.

    This stage determines the scorch and processing safety of the compound.

    At the end of this stage, the rubber starts to crosslink and loses mobility.

    The length of vulcanization induction period depends on the properties of the raw rubber, mainly depends on the auxiliaries used. For example, the delayed coking accelerant can get longer scorching time and higher processing safety.

    < /p >


    < p > a href= "http://www.91se91.com/news/index_x.asp" > sulphide < /a > induction period is a pre sulfuration stage at a certain speed.

    The degree of crosslinking in the pre vulcanization period is low, even if the breaking strength of the vulcanizate is not reached at the later stage, the elasticity can not reach the expected level, but the tear and dynamic crack performance is better than the corresponding vulcanization.

    < /p >


    After P curing, the physical properties of vulcanizate reached or near the best point, or achieved a comprehensive balance of performance.
