During the pickling process, a large amount of smoke is generated due to an increase in the pickling temperature. In particular, hydrochloric acid pickling and nitric acid pickling generate a large amount of toxic fumes, so an antifogging agent is added during the pickling process. Introduction:
During the pickling process, a large amount of smoke is generated due to an increase in the pickling temperature. In particular, hydrochloric acid pickling and nitric acid pickling generate a large amount of toxic fumes, so an antifogging agent is added during the pickling process.
Main use: It is used as an auxiliary agent for suppressing the volatilization of acid mist, promoting the removal of various oils during pickling of metals, slowing or inhibiting the corrosion of acid to metals, and having good synergistic effect with acid. Use of acid at temperature. Add various concentrations of inorganic acids (hydrochloric acid, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, etc.), organic acids (sulfamic acid, citric acid, oxalic acid, acetic acid, EDTA, NTA, HEDP, etc.), It is used in oxidizing acids and non-oxidizing acids.
Outstanding features: This product is made up of high-efficiency smoke inhibitors, acid mist absorbers, etc. It has stable performance, simple operation, small dosage, high efficiency, low cost, non-toxic and odorless, no pollution to the environment and safe to use.
Physical and chemical indicators; state: powder solid; acidity and alkalinity: weakly alkaline; corrosive: no; flammability: non-combustible
Usage: Preparation: According to the concentration and temperature of the acid, the concentration of the antifogging agent is generally 0.1~2% (weight) (the higher the temperature or concentration, the greater the concentration of the antifogging agent). The metered antifogging agent is added to the metering acid, and the mixture is evenly mixed; 2. The acid can be added after adding the antifogging agent, or the antifogging agent can be added after adding the acid; 3. The additive can also be directly added to the concentrated acid. The stock solution is used after use or after watering, but the concentration of the additive in the acid solution should not be lower than 0.1%.
