This disclosure relates to an inorganic-organic metal phosphate ceramic coating from the reaction of an inorganic phosphate of the formulas (i) A.sub.m(H.sub.2PO.sub.4).sub.m.nH.sub.2O or (ii) AH.sub.3(PO.sub.4).sub.2.nH.sub.2O; where A is ammonium or an m-valent metal element; m=1, 2, or 3; and n is 0 to 25; and at least one metal oxide or hydroxide represented by the formula B.sub.2mO.sub.m or B(OH).sub.2m, where B is a 2m-valent metal; and m=1 or 1.5; thereof; and at least one polymer capable of reacting with at least the one metal oxide or hydroxide; or a first organic precursor combined with the inorganic phosphate and a second organic precursor combined with the at least one metal oxide or hydroxide, the second organic precursor configured to chemically react with the one or more first organic precursor.

This application relates to a treating method for magnesium oxysulfate cement (MOS) or magnesium oxychloride cement (MOC) articles. The MOS or MOC article is molded, cured and dried, then the article is treated in water soluble phosphate solution for periods of 0.5 to 90 minutes. When the MOS or MOC article is treated in water soluble phosphate solution, phosphate can penetrate into MOS or MOC article, react with the non-active magnesia remaining in MOS or MOC article to form magnesium phosphate cement (MPC). After such treatment, MOS or MOC phase is bonded by magnesium phosphate cement (MPC), many defects for MOS or MOC article, such as cracks, distortion, chalking, effloresce, poor durability, and so on, can be reduced or eliminated.

A surface treatment composition including polymeric complex nanoparticles used in a hydrophobic agent and siloxane complex nanoparticles used in a suspending agent thereof. The composition of the present invention is a solution comprising a plurality of components. The primary components are an acid mixture and a base mixture that are combined together in a manner to be described herein to produce a two-part liquid solution. The two parts, are combined together prior to application to a surface and allowed to cure on the surface.

Embodiments of the present disclosure relate generally to coating compositions which are suitable for use as sealing agents, methods of making and uses thereof. The disclosed coating compositions may be particularly suitable for application as a sealing agent to a burnished surface of a cementitious substrate, such as the cut face of a fiber cement board.

This disclosure relates to an inorganic-organic metal phosphate ceramic coating from the reaction of an inorganic phosphate of the formulas (i) A.sub.m(H.sub.2PO.sub.4).sub.m.nH.sub.2O or (ii) AH.sub.3(PO.sub.4).sub.2.nH.sub.2O; where A is ammonium or an m-valent metal element; m=1, 2, or 3; and n is 0 to 25; and at least one metal oxide or hydroxide represented by the formula B.sub.2mO.sub.m or B(OH).sub.2m, where B is a 2m-valent metal; and m=1 or 1.5; thereof; and at least one polymer capable of reacting with at least the one metal oxide or hydroxide; or a first organic precursor combined with the inorganic phosphate and a second organic precursor combined with the at least one metal oxide or hydroxide, the second organic precursor configured to chemically react with the one or more first organic precursor.

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.
