A molded three-dimensional insulator that is suitable for use in an end cone region of a pollution control device and a method of making the insulator are described. The insulator includes ceramic fibers that have a bulk shrinkage no greater than 10 weight percent. The ceramic fibers can contain alumina and silica and can be microcrystalline, crystalline, or a combination thereof.

A production method of pseudo-wood and pseudo-stone furniture or ornament material with natural grains has a characteristic in that, the magnesia, the magnesium chloride, the water and the glass fiber are used to function as the primary staple. Then, a determined amount of modifier, sawdust powder and talcum powder is added into the primary staple. Then, the mold and the framework are operated according to the determined steps. Then, the primary staple is shaped. Then, the primary staple performs an oxidation process to form the product. Thus, the product is directly manufactured by the mold, without needing multiple and complicated working steps.

Disclosed are a microcapsule for self-healing concrete and a preparation method thereof, and a self-healing concrete and a preparation method thereof. The microcapsule comprises a core and a wall, the components of the core comprising a healing agent, microcrystalline cellulose and Tween 80, and a material of the wall being a high-molecular organic material sensitive to stress of cracks. The preparation method for the self-healing concrete comprises steps of: weighing appropriate amounts of cement, sand, water and the above microcapsules, with each cubic meter of concrete containing 0.05 to 0.08 cubic meter of the microcapsules; stirring the cement, sand and microcapsules until uniformly dispersed to obtain a mixture; and pouring the water into the mixture, and stirring uniformly.

A method for performing selective bacteriostasis of a sulfate-reducing bacterium, the method selectively inhibiting proliferation of the sulfate-reducing bacterium by allowing chelated Al to coexist in an environment where the sulfate-reducing bacterium exists, and a gypsum composition containing calcined gypsum (A) and chelated Al (B), in which the chelated Al (B) is contained in a range of 0.01 to 20 mass parts relative to 100 mass parts of the calcined gypsum (A).
