Compatibilized resin-cement composite compositions

Various embodiments disclosed relate to compatibilized resin-cement composite compositions and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation that includes placing in the subterranean formation a resin-cement composite composition. The resin-cement composite composition includes a resin, a cement, and a substituted or unsubstituted poly(alkylamine) compatibilizer.

FULL-FIBER BURNER BRICK AND PREPARATION METHOD THEREOF

A full-fiber burner brick and a preparation method thereof, comprising mixing alumina crystal fiber and amorphous ceramic fiber with both of them being a combination of fibers of different lengths gradations, and moreover adding fine powder fillers of different particle size gradations and supplementing other additives. This enables the internal structure of the product more uniform, increases the bulk density of the product, and also benefits the suction filterability of fiber cotton blank, and is conducive to forming and improving the strength of the blank. The surface of the brick body is further provided with a coating, which can effectively protect the cotton fiber of the brick body fiber from harsh environments, improve its high temperature resistance, and help to extend the service life of the burner brick.
