First, the formation of rust. Rust mainly by the iron stone formed by the oxidation reaction. Iron, water, oxygen is formed by three elements contributed to rust. Usually, we respond by pitting the different levels will be divided into two categories:
(A) deep rust. Many varieties of stone, especially granite contains a certain percentage of iron content, when the iron content of water and oxygen full contact, can cause oxidation and rust formation. Particularly prone to this rust stone, such as: the United States of white linen, Sandstone White (flower), rust stone (slate) and so on. In addition, the alkali in cement under the action of water and stone in the reaction of the iron will rust to form.
(B) of the surface rust. Stone in the mining, processing, transportation, installation process, the surface of iron objects in contact with a small amount of iron left by the remnants of the iron residues with moisture in the air, produce oxygen, oxidation and rust formation.
Second, the rust treatment. Rust treatment methods is the use of herbicides to be processed. Rust during processing, should note the following:
(A) try to avoid direct use of oxalic acid cleaning stone rust spots, simply because of the oxalic acid rust (Fe2 +) oxidation and reduction, oxidation reduction of iron ions remain unstable, it is easy with water and oxygen in the air re-oxidation reaction Rebuild rust, as the oxalic acid solution and will further expand the flow of rust in the area. This is why when using oxalic acid rust rust will be more than the more reason than the greater.
(B) The selection of herbicides, be sure to use good quality products. Because a good rust remover in addition to other components of acid, in addition to adding the right amount of additives to maintain the redox stability of iron ions. With this rust remover rust treated protective treatment even if the do, it can keep for a long time will not relapse. On the contrary, some herbicides are only a simple mixture of acid, redox reactions can not keep the stability of iron, recurrent high.
(C) The composition of the different components of marble and granite, nature is not the same. Main components of marble calcium carbonate, alkaline; main components of granite silica, acidic. So the use of herbicides, be sure to distinguish between the marble and granite herbicides herbicides. Granite rust remover rust must not be used for marble processing.
(D) treatment of surface rust, just brushing the surface with a rust remover can be. Sometimes, the surface grinding and polishing methods can be used for processing; deep rust treatment is relatively complex, the need to maintain a certain dose and reaction time. Sometimes need to re-use to achieve the desired effect.
(E) stone construction in the use of herbicides, the proposed re-use water to wash again, dry stone curing agent must use good quality protective treatment. Aimed at the elimination of residues after oxidation and prevent the recurrence of oxidation.
Travertine, the rust prevention. Rust prevention to its formation based primarily on three elements: water, oxygen and iron to carry out effective control of the. Combined with years of management experience, we will be the main effective method of preventing rust summarized as follows:
1. Stone in the construction before, be sure to use high-quality stone maintenance agent for six of the stone surface protective treatment, the iron block of stone and water contact.
2. Try to avoid using high alkaline cement for bonding stone construction, reducing alkali cement stone in the iron reacts with the opportunity.
