MATERIALE SINTETICE FLUORURATE, COPOLIMERI AI TETRAFLUORETILENEI - V. POPESCU PIETRIS, STELIANA SOCOLIUC

The book comprises in the first part generalities regarding florurated organic compounds. Ip this chapter, there are presented briefly the proceedings to obtain florurated organic compounds, insisting upon the production of layers to cover from fluorocarbides on polymers surfaces, through the proceeding of direct fluor-plating. Also, there are presented certain classes of fluorurated compounds: chlorofluorocarbides (freezing agents); florurated and chloroflorurated olefines - monomers with the description of the technologies to obtain them and their properties.
In the second chapter, there is done an informative presentation upon the special polymers with fluor content, which is another research domain due to the manufacturing problems and use field of these fluorurated synthetic materials.
in the next chapters there are fully described the tetrafluorethylene copolimers: copolimer ethylene-tetrafluorethylene (ETFE), copolimer tetrafluorethylerie-hexafluorpropylene (TFE-HEF) or ropolimer ethylene-propylene fluoride (FEP), copolimer tetrafluorethylene-perfluoralchiviniether (TFEPAVE) or perfluoroalcoxi (PFA). These fluorurated materials have properties similer or comparable with those of polytetrafluorethylene (PTFE) from the point of view of chemical, thermic and mechanical resistence. They can be processed through classical methods of transformation of thermoplastic materials (injection, extrusion, thermoformation, welding, etc).
mechanical and chemical properties, proceedings, technologies, work protection measures, specific fields For each material separetly there are presented proceeding for industrial obtaining, physicoof use. The book is accompanied by a reach bibliographic material, tables and pictures, which permit the wide acknowledgement of these fluorurated materials.
employment of installations, devices and items obtained from fluorocarbides, as well as to the students The scientifical work is adressed tothe engineers staff, who deals with drawing, processing and from the faculties of engineering in the field of spaceships, cars, electrotechnics, arhitecture and chemical devices.
