Types of bridge bearing  1. Elastomeric Bearing a.Plain elastomer pads b.Laminated Elastomeric bearings 2.Sliding bearing Mechanism a. PTFE  sliding material b.Alternative sliding material 3.High load multi Rotational building: a.Pot bearing b.Disc bearing c.Spherical bearings 4. Fabricated steel mechanical bearing a.Rocker bearing b.Rocker cum rolling bearing Elastomeric Bearing: It consists of elastomer manufactured from synthetic or natural rubber and can take both translation and rotation movements through elastomer deformation. The ability of elastomer to carry large vertical loads is because of reinforcement provision that prevents lateral bulging of elastomer. There are number of elastomeric bearing pads classified based on types of reinforcements used. For example, steel reinforced, plain, fiberglass reinforced and cotton duck reinforced elastomeric bearing pads Strength and response of each type is different, steel reinf...

Calendering

Image
Introduction: Calendering is the process of making thin sheet of rubber and also lamination of such sheet on to other substrate like fabric,cord warp sheet by passing through set if rollers under controlled Conditions. A calendar comprises of a number of rows or bowls held in frame. Rolls rotate in opposite directions either with even speed or with a friction ratio. Types Of Rubber material used Elastomers that can be used include: ·          Neoprene ·          SBR ·          Natural ·          Hypalon ·          Urethane ·          EPDM          Viton           Fluroelastomer         Butyl          Nitrile ...

Image
Introdu ction: It is the first synthetic rubber developed commerically.In terms of consumption polychloroprene has become a most important speciality rubber for non tyre application Special properties: excellent flame resistance Properties: Good ozone resistance Good flame resistance History if CR The polychloroprene story started in 1925 with the synthesis of the monomer. 1938-  DuPont began marketing the polymer as neoprene. 1940-  Development of copolymer with sulfur made 1950-  Soluble sulfur free mercaptan modified grades were introduced. 1960- pre cross-linked grades were developed 1970- improved. Pre cross-linked grades were developed. 1980- xanthogen disulfide grades were developed 1990- Newly developed M and XD grades combining low Temperature flexibility, heat resistance and dynamic properties as well as low fouling. T he major Manufacturers of Chloroprene rubber are 1.  Denka 2.  Neoprene 3.  B...
