Epoxy Ceramic Particles

Ceramic particulate useful as a proppant in hydraulic fracturing and in gravel packing operations is provided which comprises a ceramic sometimes vitreous core surrounded by an epoxy resin coating.

Epoxy ceramic particles. In 1993 marshall created a solution by atomizing epoxy and other filler materials to create a fine environmentally friendly insulation powder. The operating principle of this software which has been developed by the mechanical engineering department of federal university of espirito santo ufes consists of the intersection count of the phases with lines pre established by the analyzer. Ceramic epoxy coating is a unique abrasion resistant coating that protects by binding ceramic particles to a resin system thus creating an encapsulating ceramic shell. The material known as mcc 1 or marshall convergent coating 1 contained tiny hollow glass spheres and particles of cork and epoxy.

For use in processing equipment that carries small particles less than 1 16 in diameter these ceramic filled epoxies rebuild and repair surfaces exposed to abrasion from particles such as dust collectors fan blades and fan housings. The product can be used to resurface worn or damaged metallic surfaces subject to fluid erosion and corrosion.

Dry ceramic particles were deposited on the surface by sieving using either a 50 mesh 300 m or a 100 mesh 150 m depending on the size of each ceramic particle to achieve 300 420 m thick coatings. Each ceramic particle is resin coated and becomes tightly packed in the cured film. A two component solvent free epoxy flow efficiency coating containing hardened ceramic particles to give outstanding abrasion resistance. The application process was also changed.

Novolac epoxy resin compounds without any substantial acid soluble filler are used to coat ceramic particulates similar to those disclosed in u s. The product can be used to resurface worn or damaged metallic surfaces subject to fluid erosion and corrosion and is proven to improve flow rates through process equipment. The mechanical properties of the mwcnts ceramic particles and mwcnt ceramic particle filled epoxy composites are summarized in table 1. The coated laminates were cured at room temperature for 12 h and then post cured at 80 c for 24 h.

In the singly filled epoxy composites the average flexural strength was approximately 30 mpa and that of the mwcnt filled composite was slightly larger than those of the ceramic particle filled composites. 202 ceramic repair fluid a two component solvent free epoxy repair fluid containing hardened ceramic particles to give outstanding abrasion resistance.
