Description
Technical Field
The invention relates to the technical field of metal surface treatment, in particular to a corrosion and fog inhibitor.
Background
Ordinary carbon steel is easy to rust, and an oil stain layer and a corrosion layer on the surface of the ordinary carbon steel need to be removed before processing and use. The most common method in industry is to dissolve and remove the rust layer and the oil stain layer by using acid liquor and other additives as rust removers, and the method has the advantages of lowest cost and simple operation. In the hydrochloric acid pickling process, on one hand, the hydrochloric acid has certain volatility and is directly volatilized into the atmosphere to generate acid mist; on the other hand, hydrogen is generated on the surface of the steel through oxidation-reduction reaction and gradually forms bubbles, when the bubbles gradually increase to be more than about 0.3mm in diameter, the buoyancy of the bubbles exceeds the interfacial tension, the bubbles are separated from the metal surface and are accelerated to rise from hydrochloric acid until the acid liquid and the air interface burst, and the generated splash liquid drops are sprayed into the atmosphere at the speed of 10m/s, so that a large amount of acid liquid enters the atmosphere in the form of tiny liquid drops and is stably suspended in the air to form acid mist.
After the formation of acid mist, the following serious hazards will occur: firstly, the conditions of a working site are worsened, and the physical health of workers is seriously injured; secondly, serious pollution is caused to the atmosphere and the surrounding environment; thirdly, production facilities and equipment are seriously corroded, and the service life of the equipment is greatly shortened; and fourthly, the acid liquor is excessively lost, so that unnecessary waste is caused. Various problems caused by hydrochloric acid mist are increasingly prominent, and the harmfulness is increased, so that an efficient and economic method is urgently needed to solve the problem of the hydrochloric acid mist.
In order to reduce or slow down the volatilization of acid mist, a corrosion-inhibiting fog inhibitor is usually added into the acid liquor to inhibit the generation of the volatilization of the acid mist, simultaneously promote the removal of various oil stains in the metal pickling process, slow down or inhibit the corrosion of acid to metal, has good synergistic effect with the acid, and is suitable for acid use at various temperatures. The existing corrosion and fog inhibition agent needs to be fully stirred after acid liquor is added in use, so that the acid washing efficiency is influenced, the use cost is increased, and in addition, the acid fog isolation effect of the existing corrosion and fog inhibition agent is not good and needs to be improved.
