First, the formation of rust Rust is mainly Stone The iron made by the oxidation reaction. Iron, water, oxygen is formed by three main factors contributed to rust. Usually, we respond by rust levels can be classified into two different categories:

(1) deep rust. Many Stone Drugs, especially granite contain a certain percentage of iron content, when the iron content of water and oxygen full contact, can cause oxidation to produce rust. Particularly prone to rust stone such as: American white linen, Shandong White (flower), Rust ( Slate ) And so on. In addition, Cement In alkaline water and the stone under the action of the reaction of the iron will rust formation.

(B) of the surface rust. Stone in the mining, processing, transportation, installation process, the surface and iron objects, leaving a small amount of iron in contact residues, residues of these iron with air moisture, oxygen produces oxidation and rust formation.

II processing of rust spots Approach rust rust agent is mainly used to deal with. During rust treatment, should note the following:

(A) try to avoid the direct use of oxalic acid cleaning stone rust, because the acid is simply rust (Fe2 +) oxidation and reduction, oxidation reduction of iron ions remain unstable, it is easy with water and oxygen in the air again oxidation reaction to regenerate the rust, and will flow with the oxalic acid aqueous solution to further expand the area of rust. This is why when using oxalic acid rust will rust more than the more reason than the greater.

(B) use rust agent, be sure to use good quality products. As good rust agent in addition to other acid ingredients, plus also have the right amount of Additive Redox reactions to maintain the stability of iron ions. Using this agent treated rust rust protection even if do not do processing, but also to keep a long time will not relapse. On the contrary, some rust agent is a simple mixture of some acid, can not maintain the iron redox reactions in the stability of the high recurrence.

(C) The composition Marble Granite composition and different properties are different. Marble The main ingredients of calcium carbonate, alkaline; granite of the main component is silicon dioxide, acidic. So using the rust agent, be sure to distinguish between marble and granite Rust Remover Rust Remover. Agent must not be used for rust granite marble rust treatment.

(D) treatment of surface rust, just brushing the surface with a rust agent can. Sometimes, it can use the method of surface grinding and polishing treatment; deep rust to deal with relatively complex, the need to maintain a certain dosage and reaction time. Sometimes need to re-use to achieve the desired results.

(E) the use of rust agent stone construction, the proposed reuse of water clean again, dry curing agent certainly use good quality protective stone treatment. Aimed at the elimination of residues after oxidation and prevent the recurrence of oxidation.

3, rust prevention Rust prevention to its formation are based mainly 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 way to prevent rust summarized as follows:

1. Stone in the construction before the stone must be of high quality curing agent for six of the stone surface protective treatment, block stone and water in contact with iron.

2. Try to avoid using high alkaline Cement Adhesive for stone construction, reducing the alkali in cement stone in iron chance of a reaction.
