Additive for inhibiting efflorescence of non-metallic material products, its production method and use

Abstract

The invention discloses an additive capable of inhibiting the whiskering of a non-metal material product and a preparation method and application thereof, and belongs to the technical field of inorganic non-metal materials. Because the additive contains industrial salt and is prepared through blending, drying, grinding, inspection and packaging, the additive can be used for inhibiting the phenomena of alkali-aggregate reaction of a concrete product and whiskering of a gypsum product. The additive disclosed by the invention is extensive in raw material, simple in preparation method, low in cost and extensively used for an overpass, a road, a building or a gypsum product industry, and can be used for greatly prolonging the service life of the concrete product, enhancing the radiation resistance and prolonging the coagulation time when used for the concrete product, thereby being convenient for modern concrete construction; in addition, the additive disclosed by the invention can be used for greatly enhancing the whiteness and strength of the gypsum product when used for the gypsum product.

Description

technical field [0001] The invention relates to an additive for inhibiting efflorescence of non-metallic material products, a manufacturing method and application thereof, and belongs to the technical field of inorganic non-metallic materials. Background technique [0002] The prevention of alkali-aggregate reaction in inorganic non-metallic material products has been written into the "Standardized Quality Management Regulations for Building Materials" as early as the 1980s. There were reports of major safety accidents involving alkali reaction, so people gradually relaxed their vigilance against its hazards. With the continuous deepening of reform and opening up, some advanced foreign construction methods have also been introduced into our country, and additives suitable for various construction methods have also emerged as the times require, such as water reducing agents, pumping agents, retarders, early strength agent, etc.; [0003] Since the above-mentioned additives ...

AI Technical Summary

Problems solved by technology

[0003] Since the above-mentioned additives are all made of naphthalene and benzenesulfonic acid in developed countries in Europe and the United States, there are many manufacturing links, complicated processes, and high costs. Some sodium ions and sulfate ions; another factor is the rapid development of the inorganic non-metallic material industry in the past two decades. The cement industry alone has reached nearly 3 billion tons from 110 million tons in 1994 to the end of last year. The annual consumption of various The ore amounted to more than 5 billion tons. Therefore, various high-quality raw and fuel materials are far from meeting the needs of my country's rapid development, and some raw materials whose content of harmful substances have approached or exceeded the critical point have also been mixed into the production line.

It can be seen that the superposition of the above two factors has gradually exposed the potential safety hazards of inorganic non-metallic material products, resulting in bridges and roads that have to be demolished and rebuilt within a few years. Driving on a very smooth road is already a very rare luxury.
