Provided is a safe, environmentally friendly, efficient,Aluminum for building and easy-to-operate aluminum formwork cement slag high-efficiency cleaning agent for construction and a preparation method thereof. The technical solution of this patent technology is: a high-efficiency cleaning agent for aluminum formwork cement slag for construction,Aluminum for building which is characterized by the following raw materials and mass percentages: sodium dihydrogen phosphate 1-15%,Aluminum for building sodium tungstate 0.1-10%, mass percentage The concentration of 90% nitric acid is 50~80%, fluozirconic acid is 1~10%, and water is 10~20%.
A method for preparing the above-mentioned high-efficiency cleaning agent for aluminum formwork cement slag for construction is carried out in sequence as follows: add water into a stirred tank, add sodium dihydrogen phosphate, sodium tungstate, nitric acid,Aluminum for building and fluozirconic acid in sequence and mix and stir uniformly That's it. This patented technology is an acidic cleaning agent with a pH value of 1.0 to 2.0.
A variety of raw materials are compatible with each other,Aluminum for building especially the combination of aluminum film and pickling, which can quickly remove cement slag and form a passivation film on the surface of the aluminum template,Aluminum for building which has a good anti-corrosion protection for the aluminum template; During the cleaning process,Aluminum for building no irritating gas harmful to the human body and the environment will be produced. It is safe, environmentally friendly, efficient,Aluminum for building easy to operate...
