What is the procedure of rubber making?

 

Rubber production involves several steps, primarily for natural rubber, which is obtained from the latex of the rubber tree. Here’s an overview:

 

Harvesting: Latex, the milky substance containing rubber particles, is collected from rubber trees. This process involves making incisions in the bark of the tree and collecting the latex in containers.

 

Coagulation: The collected latex is then treated to coagulate the rubber particles. This can be done by adding acid or by using a coagulant like formic acid or calcium nitrate. Coagulation causes the rubber particles to come together and separate from the liquid.

 

Forming: The coagulated rubber is then formed into sheets or blocks. This can be done manually or using machines. The formed rubber is then washed to remove impurities.

 

Milling: The rubber sheets or blocks are passed through mills to further refine and homogenize them. This process helps to break down any remaining lumps and improve the quality of the rubber.

 

Vulcanization: Vulcanization is a chemical process that involves heating the rubber with sulfur and other additives. This process cross-links the rubber molecules, making the material more durable, elastic, and resistant to heat and chemicals. Vulcanization is crucial for giving rubber its desirable properties.

 

Finishing: After vulcanization, the rubber is shaped into its final form through processes like molding, extrusion, or calendaring. It may also undergo additional treatments such as washing, drying, and finishing to enhance its appearance and properties.

 

Quality Control: Throughout the production process, quality control measures are implemented to ensure that the rubber meets the desired specifications and standards. This includes testing for strength, elasticity, durability, and other properties.

 

These steps outline the general procedure for natural rubber production. Synthetic rubber production follows a different process, typically involving the polymerization of petroleum-derived monomers.

 

 

 

List of ingredients used in rubber making?

 

Rubber can be made from either natural sources or synthetic materials. Here’s a list of ingredients commonly used in both natural and synthetic rubber manufacturing:

 

Natural rubber latex: The primary ingredient in natural rubber production, obtained from the latex sap of certain trees, especially the Hevea brasiliensis tree.

Synthetic rubber polymers: Various synthetic polymers can be used, such as styrene-butadiene rubber (SBR), polybutadiene rubber (BR), polyisoprene rubber (IR), and ethylene-propylene-diene monomer (EPDM).

Fillers: Substances like carbon black, silica, clay, and calcium carbonate are added to improve the mechanical properties and reduce costs.

Vulcanizing agents: Compounds such as sulfur or peroxides are used to cross-link the polymer chains, increasing the rubber’s strength, elasticity, and durability.

Accelerators: Chemicals like zinc oxide and accelerators such as thiurams, mercaptobenzothiazoles, and dithiocarbamates are added to speed up the vulcanization process.

Antioxidants: Prevent degradation of the rubber due to exposure to oxygen and heat. Examples include phenols and amines.

Plasticizers: These are used to improve flexibility and reduce stiffness. Oils and resins are common plasticizers.

Softeners: Materials like pine tar or petroleum resins can be added to adjust the hardness or tackiness of the rubber.

Activators: Substances like zinc oxide are used to enhance the effectiveness of accelerators.

Antiozonants: Protect the rubber from degradation caused by exposure to ozone, which can lead to cracking. Examples include waxes and chemicals like paraphenylene diamine (PPD).
