At this stage, many buildings and public places have begun to use Lixin concrete sealing and curing agent to strengthen the performance of the floor. However, after the construction, some people react that the performance of the floor after construction is fundamentally different from what they said before, and the hardness, anti-seepage and gloss are not all good.

The anti-corrosion coating is a coating formed after drying and curing on the surface of the substrate to be coated. Its protective effects mainly include the following three types: shielding effect. According to the principle of electrochemical corrosion, the corrosion of steel must have the existence of oxygen, water and ions, as well as the way of ion flow and conduction. The paint film prevents the existence of corrosive medium and material surface, Blocking the path of the corrosive battery increases the resistance. The penetration rate of water, oxygen and ions to the paint film is different. The penetration rate of water is much higher than that of ions and oxygen. There is less direct penetration of the paint film, so their direct effect on the substrate metal can be ignored.

[Industry dynamics] What is the difference between the properties of thermosetting resin and thermoplastic resin?

The main differences between thermosetting resin and thermoplastic resin are: ① different solvent resistance. The thermoplastic resin produced by polymerization has strong resistance to organic solvents, so most synthetic fibers can be dry cleaned, and only spandex has poor resistance to solvents; Thermosetting resins such as buttons, resin bead drills and coatings are generally not dry cleaned.
