Quality Fluoroplast Against Wear

Specially manufactured fluoroplastic parts increase the service life of technological equipment (especially exposed to abrasive media) by three to four times.

It is known that the main direction of the fight against corrosion in the chemical industry is the protection of metal. Despite the continuous improvement of the quality of plastics and composites, most of the currently used process equipment is still made of metals.

Products made of PTFE have high wear resistance. How much this material improves the quality of the operation of the units, improves such elements of machines as sliding bearings, liners and cuffs, thousands of customers of ECO-RTI-Holding have already convinced themselves. Among them, first of all, chemical and machine-building enterprises, which, thanks to the quality of fluoroplastic, were able to reduce the cost of repairing compressors, machines and all kinds of friction units.

With regard to the hardness of the products, this Teflon polymer is superior even to previously used detonation spraying on piston rods. Based on the polymerization of tetrafluoroethylene, the production of PTFE provides it with an exceptional Brinell hardness of up to 40 MPa and virtually zero porosity. As a result of the chemical process, a substance with a density of 2200 kg / cm3 is created, which under the scanning electron microscope has a convex surface structure. This slightly rounded surface is in stark contrast to the concave, with an edge structure, typical of non-wear resistant materials.

Filled PTFE is one of the few polymers from which elements of centrifugal pumps can be made . The advantage of the latter in comparison with analogues of metal (with facing insulated coating) is to eliminate the difference in the values of the thermal expansion of the lining and the metal. Distributors, redistributors and seals - internal reinforcement - are also protected by applying fluoropolymer compounds.

Sealed joints, FUM tape and trouble-free operation.

From fluoroplastic blanks are made membranes, gaskets and sealing rings, the operation of which does not actually require preventive and emergency maintenance. Noteworthy is not only the achievement of high hardness for Brinell, 20-25 units higher than the hardness of other materials available on the market. Along with zero water absorption, the fluoroplastic rod or plate plays an important role in reducing the abrading ability with respect to the moving surfaces.

In contrast to various composites with a concave microstructure, the rings and bushings of PTFE do not wear out by shearing, which preserves the stability of minimum friction. In addition, the strength and reliability of certain joints, gaps and lap fasteners can only be provided by the FUM tape, which is made of a fluoroplastic harness to seal the hydraulic connections. Also buy a tape FUM seek to protect mounting holes with low diffusion values of steam and gas.
