Glued prepregs – promising materials for metal–polymer structures

The individual stages of investigations aimed at increasing the service life and longevity of aviation systems are discussed. The outstanding properties of glued prepregs are indicated and the results of application discussed. The results obtained in investigating a new class of aluminium-polymer–laminated materials SIAL – a hybrid material based on thin aluminium sheets made of constructional alloys and fibreglass based on glued prepregs produced from adhesive binders of the molten type and glass fillers with different reinforcement structure – are also presented.     

System for Final Cooling of Coke-Oven Gas and Byproduct Extraction at Durgapur Steel Plant

A new system for final cooling of coke-oven gas has been installed in the byproduct-capture shop of the coke plant at Durgapur Steel Plant (India). This system, designed by AO VUKhIN under a contract with Bengal Tools Limited (now BTL EPC, India), also removes naphthalene from the gas and ensures the absorption and distillation of benzene. The main design features are outlined. The treatment technology for the coke-oven gas is described; along with the organization of the final cooling and the removal of naphthalene, the trapping of phenolic hydrocarbons by petroleum absorbent, and the distillation of absorbing oil. This system ensures the specified quality of the products—purified coke-oven gas and raw benzene.
