Rubberizing of metal elements

Dimensions / shapes

• in a larger autoclave for maximum lengths up to 6 m, up to 3 m in diameter
• in a smaller autoclave for maximum lengths up to 3 m, up to 1.5 m in diameter

Materials

- Rubber materials are prepared according to the medium for which the container or valve is intended for, the most common materials are:

• EBONIT (hard rubber 70 Sh D scale), outstanding chemical resistance
• CLIIR (Clorbutyl Rubber 45 Sh A Scale), low chemical resistance, vulcanized
• NR - SBR (tire with increased abrasion resistance)

The materials used to protect the rubberized elements against the corrosive and abrasive effects of the media present in them.

Technological processing process

• preparing the surface of the rubber container
• preparation and application of rubber compound
• steam and hot water vulcanization
• finishing
• leakage testing / control by electro-induction method
• supporting documentation: guarantee of the quality of the work performed, certificate of electro-induction testing of the rubberized surface, attestation and technical characteristics for the embedded material and diagram of vulcanization

Application

• Rubberizing of different tanks for aggressive media (acids, alkalis)
• complete pipelines or parts thereof
• valve housings (diaphragm valves)
• swimming pools
• vibrators for cleaning metal forgings
• anion-cation exchanger
• various galvanic tubs and more

Dimensions / shapes

• it is possible to rubberize rollers up to 5000 mm in length and up to 720 mm in diameter

Materials

• the material is selected based on the application and the media it comes in contact with, temperature, pressure, speed, machine characteristics
• NR, SBR, IIR, EPDM, VMQ, CR, NBR, HNBR, FKM, EAM, CSM, AU / EU, ECO
• the rubberized layer protects against wear the expensive metal core of the rollers
• quick and repeated restoration of the rubber layer is possible, which reduces maintenance costs and reduces production processes

Technological processing process

• preparation of the metal core of the roller by shot
• coating with crude rubber compound - vulcanization of rubber element in autoclave
• sanding finish
• electroinduction testing

Application

• rollers for transport (metal, construction, wood industry)
• paint rollers (printing industry)
• rollers for adhesive application (production of wood elements)
• rollers as drive elements for various conveyors, conveyor belts, etc.
