High-performance acid mist absorption filter ball

Abstract

The invention belongs to the field of environmental protection, and particularly relates to a high-performance acid mist absorption filter ball which comprises an inner core and a coating layer. The coating layer is made of a porous silica material, and the inner core is made of an inorganic-organic mixed material. The problem that an existing absorbing material is poor in stability and prone to breakage is solved, a surface frame is formed by means of a silica structure, stable acid mist absorption is achieved by means of the dissolution characteristic of sepiolite and polyacrylate, and meanwhile a cross structure is formed to achieve the effect of structural complementation.

Description

technical field

[0001] The invention belongs to the field of environmental protection, and in particular relates to a high-performance acid mist absorption filter ball. Background technique

[0002] The pickling process is one of the indispensable production units in the metal products industry (including electroplating, hot-plating, steel mills, etc.), and its principle is to use acid solution (usually hydrochloric acid) to remove scale and rust on the steel surface The chemical method is one of the most commonly used methods for cleaning metal surfaces. The current pickling process mostly uses hydrochloric acid as the acid solution. However, hydrochloric acid is highly volatile and forms hydrochloric acid mist. Hydrochloric acid mist is highly corrosive to workshop buildings, production equipment, and metal infrastructure, and is highly dangerous to workshop operators. Contacting its vapor or smog can cause Acute poisoning, conjunctivitis, nasal and oral mucosa burning se...
