Professional interpretation of vulcanized shoes (vulcanizationshoe) - vulcanized shoes, canvas shoes, shoes - footwear industry
Vulcanized shoes vulcanizationshoe, rubber, fabric or Leather To help the surface, rubber base materials, with the paste, molded or injection molded plastic processing, etc., and then at a certain temperature and pressure for curing, giving upper, Sole High strength and high flexibility, and make the two firmly together, so called vulcanized shoes. With sulfur Chemical industry Art's Leather shoes Vulcanized shoes known there.
Vulcanized soles are vulcanized rubber, after vulcanization of rubber products, this step is not easy cracking of aging, good flexibility, heat resistance, are now essential that rubber rubber products, also known as cooked rubber, collectively referred to as rubber or rubber.
Vulcanized shoes with soles and uppers that add sulfur to the interface means "curing laws," and made a leisurely sport shoes (in order to enhance flexibility, hardness, the rubber to sulfur treatment) vulcanized rubber shoe soles increase in the sulfur should handle the increased flexibility and hardness of rubber shoes is that after curing treatment, not only Canvas shoes , PUMA sulfide treatment was first invented in 1960.
Vulcanized shoes advantages: Fashion, look good, with the classic jeans; dirty better care of pretty, affordable;
Disadvantages: pattern is not particularly large, leather Yizhou on the giant ugly, can not do strenuous exercise, or body of the shoe a little bit heavy.
"Curing" is a historical, natural rubber products due to the initial use of sulfur as crosslinking agent for crosslinking named, with the rubber industry, can now be carried out with a variety of non-sulfur cross-linking agent crosslinking. Therefore, a more scientific significance of sulfide should be "linked" or "bridge", that the linear polymer formed by crosslinking polymer mesh process. That is, from the properties of the plastic into a flexible rubber or rubber hard rubber process. "Curing" means not only includes the actual cross-linking process, but also produces cross-linking method.
Plastic Liaoding by measuring tensile strength (or curing instrument) can be seen, the vulcanization vulcanization process can be divided into induction, pre-sulfur, sulfur vulcanization and over (for natural rubber is reversion) four stages .
Induction curing (scorch time), the cross-linking has not yet started, rubber good liquidity. This stage determines the nature of plastic materials and processing scorch safety. The end of this phase, cross-linked rubber and began to lose mobility. In addition to curing the length of induction period and the nature of raw rubber itself, mainly depends on the use of additives, such as sexual enhancers with delay can be longer scorch time, and have higher processing safety.
Induction after curing speed is linked to certain pre-curing stage. Pre-curing of the low level of cross-linking, even to the tensile strength of vulcanizates late, could not reach desired level of flexibility, but the rip tear and dynamic performance better than the corresponding vulcanization.
Reach the vulcanization stage, the physical properties of vulcanized rubber, respectively, or close to the optimal point, or the performance of the integrated whole to achieve a balance. View more Industry News>>>
