What Is Vulcanized Rubber Used For?
Vulcanization gives rubber its characteristic more elastic and durable quality ,it is vital for rubber,silicone,plastic polymer industries . the vulcanized rubber material can be used to produce many products ,including soles of shoes, hoses, hockey pucks, bowling balls, toys, tires, bouncing balls, and much more.
How Do Vulcanizing Press Work?
Vulcanisation is a thermochemical process which is vital for rubber industries. The rubber vulcanization includes a series of complicated chemical reactions with sulfur,accelerators and additives,it promotes cross-linking between rubber molecules , in order to improve the strength, abrasion, and aging resistance of the rubber. The vulcanized rubber material become more flexible ,elastic and durable than rubber that has not been vulcanised.
On the process of vulcanization , the rubber material are placed between two flat heated to a specified temperature . After high temperature and high pressure ,the rubber vulcanization is pressed into the desired shape . Here is the process of vulcanization as follows:
1. Pre-treament for Material :the rubber material to be vulcanized needs to be pre-treated, for example the material should undergo these process ,such as rubber cutting, crushing & blending, and mixing & kneading.
2. Charging and Loading Mold :the material treadted are sent to the rubber vulcanizer equipment for curing .The material are usually mixed with additives such as vulcanizing agents, accelerators, preservatives, and fillers to form a uniform rubber mixture.
3. Setting Heating & Pressure :Set some certain temperature and pressure ,process time for the vulcanization machine,which are controlled by PLC system .
Basically ,the vulcanization temperature can be adjustable as per different rubber materials and vulcanization requirements （）between usually between 140°–180° ). The vulcanization time is usually longer and can last from a few minutes to several hours.
4. Cooling and Curing: When the vulcanization reaction is completed, the hydraulic vulcanizing press machine starts the cooling system to cool the vulcanized rubber products, to cure their shape and structure.
Application of Vulcanization
The vulcanized rubber material feature higher tensile strength and thermal stability and durability ,it is 10 times more stronger than natural rubber. The vulcanized rubber material can be widely used to produce many products ,including
