Accurate selection of stone, knowing where to choose what kind of stone, knowing where to place the size of the Landscape Stone, installing the stone correctly, determining the posture of the Landscape Stone, and effectively displaying the quality of the Landscape Stone are the basic qualities of every landscape engineer. He is the effect of stone. And can be used longer. The quality of Landscape Stone is determined by its color, luster, strength and structure.
And color and gloss are often important symbols to determine the price of Landscape Stone, which can save the cost of landscape engineering and achieve good landscape effects. It is a true master of landscape architecture. Landscape Stone should not only be beautiful, but also suitable. The physical properties of Landscape Stone are determined by its material. Landscape Stone, which are different from other materials, are not accurately evaluated by geologists, but are determined by the degree of decorative effect. Landscape Stone is bright in color and can be used in many occasions. Its physical properties determine that maintenance is very convenient. When choosing Landscape Stone, you must pay attention to the quality of pure natural stone.
1. Rust remover can be used, and the rust remover must use good quality products. In addition to the acid component, a good rust remover also contains an appropriate amount of additives to maintain the stability of iron ions in the oxidation-reduction reaction. Even if the rust spot treated with this rust remover is not treated, it can persist for a long time without recurrence. On the contrary, some rust removers are only a simple mixture of some acids, which cannot maintain the stability of iron ions in the oxidation-reduction reaction, and the recurrence rate is high.
2. Try to avoid using oxalic acid to directly clean the stone rust spots, because oxalic acid simply oxidizes and restores the rust spots (Fe2+), and the oxidized and restored iron ions are still unstable, and it is easy to re-oxidize and react with water and oxygen in the air again. Rust is generated, and the area of rust spots will be further enlarged with the flow of the oxalic acid aqueous solution.
3. When dealing with surface rust spots, just brush the surface with rust remover. Sometimes it can also be treated by surface grinding and polishing; the treatment of deep rust spots is relatively complicated, and a certain dosage and reaction time must be maintained. Sometimes repeated use is required to achieve the desired effect.
4. After the stone is constructed with a rust remover, it is recommended to wash it again with clean water. After drying, it must be protected with a high-quality stone maintenance agent. The purpose is to completely remove the residue after the oxidation reaction and prevent the oxidation reaction from happening again.
5. Because the composition of marble and granite is different, their properties are different. The main component of marble is calcium carbonate, which is alkaline; the main component of granite is silicon dioxide, which is acidic. Therefore, when using rust remover, it is necessary to distinguish between marble rust remover and granite rust remover. Granite rust remover must not be used for marble rust treatment.
