What is a Rubber Liner?

Rubber Liner: Enhancing Equipment Lifespan

Rubber Liner, also known as Rubber Lining or Rubber Sheet Lining, involves using a wear-resistant, corrosion-resistant, and high-temperature-resistant rubber as a lining layer inside equipment or pipelines. By utilizing the physical and chemical properties of rubber, the impact force and corrosion effects of the transported medium on the external structure of equipment and pipelines are reduced. The cushioning effect of rubber effectively protects the equipment and pipelines, extending their lifespan significantly.

  1. Characteristics of Rubber Liner:

    Rubber Liner possesses the ability to shield metals or other substrates from various corrosive media. Different types of Rubber Liner can withstand the corrosion of acids, alkalis, inorganic salts, and various organic substances. Additionally, Rubber Liner exhibits excellent elasticity, wear resistance, impact resistance, and good adhesion to metals and other substrates. Therefore, it finds wide applications in industries such as petroleum, chemical, fertilizer, metallurgy, and power, in acid and alkali storage tanks, reactors, floor isolation layers, etc. Due to diverse usage scenarios and requirements, Rubber Liner comes in various types.

  2. Classification of Rubber Liner:

    Rubber Liner is generally classified based on usage scenarios into categories such as anti-corrosion lining, mill lining, flotation machine lining, flue gas desulfurization lining, and more.

    Rubber Liner can also be categorized based on bonding technology into hot vulcanized rubber lining and cold vulcanized rubber lining.

    Hot Vulcanized Rubber Liner: This process involves unvulcanized rubber being vulcanized under conditions such as high temperature, high pressure, and controlled sulfurization time in equipment like vulcanization tanks. During this process, the rubber achieves complete vulcanization, and the hot-vulcanized rubber is strongly bonded to the bonding surface.

    Cold Vulcanized Rubber Liner: Cold vulcanization is an advanced Rubber Liner process. It involves chemical reactions between special adhesives and semi-vulcanized Rubber Sheets for bonding. This method allows for immediate use after bonding and achieves a bonding strength of 9-12N/mm.

  3. Rubber Liner Installation:

    Rubber Liner installation involves creating a continuous isolating covering on the surface of metal or other materials using Rubber Sheets. The rubber materials commonly used for Rubber Liner include soft rubber, hard rubber, and semi-hard rubber. The installation process includes surface treatment of the metal substrate, processing and cutting of rubber sheets, adhesive application, fitting, and bonding.

    For equipment whereRubber Sheet bonding installation is not suitable, customized molded rubber lining products can be tailored according to product drawings.
