Explosive Pressing of Fluoroplastic Industrial Waste

Chemical and Petroleum Engineering (English Translation of Khimicheskoe I Neftyanoe Mashinostroenie), 2015
Explosive pressing is presented as a promising new method for processing industrial fluoroplastic waste. Optimum loading and sintering parameters are determined providing preparation of high-density compacts of fluoroplastic-4 and F4K20 chips. It is shown that high-speed loading causes polymer waste grinding forming strengthened zones over particle ...

Corrosion Protection with Fluoroplastics

CORROSION 2009, 2009
Abstract Fluoroplastics show the best chemical resistance among the plastics. Fluoroplastics are inert to almost all kinds of chemicals in the temperature range of -60 deg C to 260 deg. C. Fluoroplastics show excellent non-stick properties and low friction properties, giving these materials widespread use in the chemical and oil and gas ...

Explosive pressing of fluoroplastic composites

Materials Today: Proceedings, 2019
Abstract This work presents results of the research on morphology, thermal deformation properties of fluoroplast-4 based compositions with highly heat-resistant glassy PA polyarylate and phenylone C3 after explosive pressing of powder composite mixtures in a steel cylindrical ampoule with pressure of 0.8 GPa. It is shown that this type of high-energy

Fluoroplastic coatings in sealing devices

Chemical and Petroleum Engineering, 2006
Tests of various types of joints having sealing gaskets and fluoroplastic coating are analyzed. Tightness of these joints after the action of impact loads, elevated and reduced temperatures, cryogenic temperature, and thermal shock is assessed.

Reinforced Antifriction Epoxy Fluoroplastics

Solid State Phenomena, 2018
The materials are antifriction self-lubricating (MAS) based on epoxy fluoroplastics compositions reinforced with various fabrics having increased tribotechnical characteristics under conditions of operation without lubrication, with lubrication or in an aqueous medium. A range of antifriction materials has been developed, as well as the main properties

Lining pump components with fluoroplastics

World Pumps, 2004
It is some 30 years since it was first recognised that traditional metal alloys were not suitable for the emerging highly aggressive and potentially dangerous chemistries being developed at that time. As Peter Cunningham of Chemquip discusses, it was the short meantime before failure experienced by users that motivated pump manufacturers to seek ...

Protecting Properties of Composite Fluoroplastic Coatings

Russian Journal of Applied Chemistry, 2002
Preparation of protecting fluoroplastic coatings at varied composition of the reaction mixture was studied. Introduction of quarternary pyridinium poly salt and various pigments into the polytrifluorochloroethylene composition allows variation of the process parameters of coating deposition on the cathode and preparation of modified fluoroplastic ...

Ultrasonic method of strengthening fluoroplastic 4D

Polymer Mechanics, 1973
A method of strengthening fluoroplastic 4D (a modification of polytetrafluoroethylene) is proposed. It is shown that ultrasonic vibration in kerosene improves the strength of the material in air and extends its life in liquid media.

Composite fluoroplastic fibrous filtration membranes

Technical Physics Letters, 2005
New fibrous materials and related composite membranes have been obtained using fluoroplastic copolymer fibers produced by means of electrospinning. The composite membranes comprise alternating layers of fine and coarse fibers performing different functions: thin fibers determine the filtration properties, while thick fibers provide the necessary ...
