Lusa is a kind of bioactive material modified by a special process. It slowly dissolves and releases when it meets water, producing a large number of weak electric groups, which can be produced with copper ion, iron ion, calcium ion, magnesium ion and other cations in water, and anions such as carbonate ion, bicarbonate ion and sulfate ion The weak current interference effect can quickly inactivate the scaling factor in water, and the scale formation can be completely eliminated by using a very small amount of Lusa. Its innovative scale inhibition mechanism makes Lusa suitable for high-efficiency scale inhibition in complex water environment, such as three crystal forms of calcium carbonate scale, calcium sulfate scale, calcium silicate scale, etc.; Lusa also has self-assembly characteristics, when a certain amount of Lusa molecules are quickly adsorbed on the metal tube wall, its active end self-assembly becomes a biomembrane of supramolecular system The metal pipe wall is fully isolated from water, which plays an effective role in corrosion inhibition. The solid scale inhibition technology is still in the leading position in the world.
