The present invention provides a concrete protective agent and a preparation method thereof, and a concrete protective film and a preparation method thereof. The concrete protective agent provided in the present invention includes the following components: water, oxalic acid, a defoaming agent, and a film-forming agent. When the concrete protective agent provided in the present invention is used for concrete protection, oxalic acid in the protective agent can react with calcium ions in concrete for in situ generation of calcium oxalate monohydrate inside and on a surface of concrete to obtain a protective film with strong adhesion to concrete. The film-forming agent in the protective agent is used as a template to adjust and control growth of calcium oxalate crystals, so as to improve waterproof performance and corrosion resistance to sulfate and chloride ions of the protective film. Preparation methods provided in the present invention are simple and practical and are suitable for mass production.

Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention have many uses, such as, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.

摘要:
A material for passivating a dielectric layer in a semiconductor device has a molecular structure permitting or at least promoting liquid phase metal deposition thereon in a subsequent process step. The contemplated material may be constituted by multiple organic components. A semiconductor device including a layer of the passivating coupling material, and a method of manufacturing such a semiconductor device are also contemplated.
摘要:
Efflorescence of building material, such as portland cement based building products, masonry, brick, concrete, and mortar, can be retarded by contacting the building material with polyvinylalcohol (PVOH). The PVOH may be dissolved in solvent, preferably water, and either applied to a surface of the building material, or added to the components that form the building material. The PVOH has a hydrolysis percentage above about 90%.
