Problems solved by technology

The procurement and transportation procedures are complicated, and industrial accidents are prone to accidents in storage and use. Because of its strong corrosiveness, it is easy to damage the internal structure of concrete while cleaning calcifications, cement stones and other pollutants on the seam surface, so it has not been promoted and widely used.
In summary, its main disadvantages are: 1. Dilute hydrochloric acid is strongly acidic, has a pungent smell, is highly corrosive, and is prone to personal injury accidents during construction and use; 2. It can illegally produce drugs and is a high-risk chemical dangerous product controlled by the public security department. Its procurement and transportation procedures are complicated; 3. It is highly corrosive when used and will damage the internal structure of concrete; 4. Low cost performance

Abstract

The invention discloses a concrete crack cleaning agent, comprising, by weight, 90-99 parts of sulfamic acid, 0.9-9.8 parts of glycolic acid, 0.1-0.3 parts of surfactant OP-10 nonyl phenol polyoxyethylene acid. The cleaning agent in the invention has simple preparing process, excellent cleaning effect. The cleaning agent can satisfy demand that joint surface of the concrete crack is cleaned effectively before chemical grouting.

Description

technical field [0001] The invention relates to a material used for cleaning pollutants on the surface of concrete cracks in the construction field, in particular to a concrete crack cleaning agent which is easy to produce and has good effect. Background technique [0002] At present, the domestic concrete cracks are basically not cleaned with special cleaning agents before chemical grouting, but the chemical grout is directly poured after simply washing the joints with clean water. A large amount of calcification or cement slurry stones will be formed after the joint surface itself is polluted, and clean water cannot be cleaned. Therefore, the grout filling is not dense after chemical grouting, and the bonding force with the joint surface is poor, resulting in unsatisfactory grouting effect. It is said that dilute hydrochloric acid is used to clean the joint surface before chemical grouting in individual projects. Since dilute hydrochloric acid (alias salt strong water) is ...
