Abstract
The composite material and block system is essentially an inner sleeve that is applied to the inner walls of an emissions system in a power plant, or any other plant that generates corrosive gases as a by-product of its process, in order to provide chemical corrosion resistance, abrasion resistance and insulation. In a preferred embodiment, the novel abrasion resistant material is formed from vinyl ester resin (about 10% to about 40% by weight), coal slag (about 30% to about 70% by weight), and fly ash (about 5% to about 30% by weight).
Claims25
A composite material exhibiting anti-abrasive qualities, said composite material comprising vinyl ester resin, coal slag and fly ash.
An abrasion resistant block made from a composite material comprising vinyl ester resin, coal slag and fly ash.
A dual layer abrasive resistant block comprising:
- a first layer comprising a composite material including vinyl ester resin, coal slag and fly ash;
- and
- a second layer attached to said first layer, said second layer comprising material selected from the group consisting of borosilicate, brick and concrete.
A process for installing an abrasion resistant inner sleeve to the inner surfaces of a structure used to carry corrosive materials and the like, said process comprising the steps of:
- cleaning said inner surfaces of said structure;
- applying an adhesive agent to said inner surfaces of said structure;
- adhering abrasion resistant blocks, comprising a composite material including vinyl ester resin, fly ash and coal slag, to said inner surfaces of said structure;
- and
- applying adhesive, grout or mortar, or some combination thereof, between said abrasion resistant blocks.
A process for installing an abrasion resistant inner sleeve to the inner surfaces of a structure used to carry corrosive materials and the like, said process comprising the steps of:
- cleaning said inner surfaces of said structure;
- applying a composite material comprising vinyl ester resin, coal slag and fly ash to said inner surfaces of said structure;
- and
- allowing said composite material to cure.
