General chemical structure of a polyketone. Polyketones are a family of high-performance thermoplastic polymers. The polar ketone groups in the polymer backbone of these materials gives rise to a strong attraction between polymer chains, which increases the material's melting point (255 °C for copolymer (carbon monoxide ethylene), 220 °C for terpolymer (carbon monoxide, ethylene, propylene).
While drag chains are used for several applications and made of different materials, heavy duty drag chains are often created using steel due to its durability. This type of drag chain is often utilised within the oil and gas industry for their offshore operations. [2]
Polycarbonyl, (also known as polymeric-CO, p-CO or poly-CO) is a solid, metastable, and explosive polymer of carbon monoxide. [1] The polymer is produced by exposing carbon monoxide to high pressures. The structure of the solid appears amorphous, but may include a zigzag of equally-spaced CO groups. [2]
Drag chain may refer to: Cable carrier in moving machinery; Drag conveyor, for moving bulk material; A type of chain shift in linguistics; Part of a dragline excavator;
Aluminium carbide is prepared by direct reaction of aluminium and carbon in an electric arc furnace. [3] 4 Al + 3 C → Al 4 C 3. An alternative reaction begins with alumina, but it is less favorable because of generation of carbon monoxide. 2 Al 2 O 3 + 9 C → Al 4 C 3 + 6 CO. Silicon carbide also reacts with aluminium to yield Al 4 C 3.
The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. [2] Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects.
Traction cables (cable chains, snow cables) attach like chains but are made from cable rather than chain. Chain patterns include the ladder, diagonal, or pattern types. Ladder-type chains have cross chains perpendicular to the road and look like a ladder when carefully laid on the ground. With diagonal chains, the cross chains are diagonal to ...
In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates. Ions of carbon are carbocations and carbanions are also short-lived. An important carbon property is catenation as the ability to form long carbon chains and rings. [3]
