The Formation and Treatment of Common Natural slate Diseases

The Natural slate lesions rust stains,Formed from two aspects: First, the natural reaction generated. Because the material inside the Natural slate contains hematite and pyrite, these iron minerals are exposed to air oxidation and the formation of ferric oxide (rust), through the Natural slate pores bleed; the second is because the Natural slate in the mining , Processing, transportation, installation, use and other processes, the inevitable contact with iron items, the residual iron objects dip in the Natural slate surface, was oxidized after the formation of rust pollution.

The key to the prevention of rust marks is the Natural slate must be installed before the use of resin injection method to make Natural slate with waterproof function to prevent the Natural slate within the iron minerals are oxidized after the exudation of Natural slate surface. After installation must thoroughly clean the Natural slate, to prevent the Natural slate due to external pollution caused by rust marks. In the construction method as far as possible the use of dry hanging way, especially as the United States such as white linen more prone to rusty Natural slate, should avoid the use of wet construction methods. 

If necessary, before the installation can do a full range of rust and water treatment The Processing of the rust has been the main products at home and abroad is the rust agent, the ideal derusting agent should have two conditions: the first Natural slate material after rust will not rust; Natural slate, does not affect the Natural slate surface gloss. However, because the rust is acidic, so in the marble (calcareous Natural slate) rust in advance to do the experiment, it is necessary to add water dilution. In the rust, thoroughly cleaned with water, and then protective agent for protection, so that the Natural slate has a waterproof function to prevent the occurrence of other diseases in the future and due to chemical corrosion caused by the trouble.
