The Formation and Treatment of Common Marble Column Lesions

Abstract: Marble columns coloring: physical or chemical methods on the marble columns by color or color change processing to eliminate the natural color of the Marble columns, or to restore the color of the marble has produced the color of the stone. Marble columns protection, cleaning and coloring technology are interrelated, mutual penetration, complement each other, are to prevent or eliminate the marble columns lesions, marble columns conservation technology is an essential part of the essential.

Marble columns are durable, has gradually entered the millions of people home, but we all thought that the marble columns will be once and for all, but I do not know in the daily living environment, dust, waste gas, acid rain, frozen and other pollutants on the marble columns The destruction of. Such as unclean conservation of marble columns, will greatly reduce the greatly reduced the decorative effect of marble columns and the service life.

The main reason for the treatment of marble columns: First, some of the material inside the marble columns and the material in the atmosphere of the chemical reaction formed; and the second is caused by increasingly serious air pollution; Third, because the marble columns in the installation of improper construction methods Caused.

Therefore, the prevention of marble columns lesions (treatment) and treatment (cleaning and coloring) becomes essential. The prevention of marble columns lesions is mainly through the protection of the marble columns to solve, and the treatment of marble columns lesions need to take the method of cleaning and coloring.

Marble columns protection: the marble columns to take brushing protective agent to protect the way to prevent or delay the marble columns pollution, fade or even damage and other diseases.

Marble columns cleaning: physical or chemical methods to clean up the surface of the marble columns or superficial pollution and other lesions, is one of the main methods of treatment of marble columns lesions.

Marble columns coloring: physical or chemical methods of the marble columns by color or color change processing to eliminate the natural color of the marble columns, or restore the color of the marble has produced the color of the marble.

Marble columns protection, cleaning and coloring technology are interrelated, mutual penetration, complement each other, are to prevent or eliminate the marble columns lesions, marble columns conservation technology is an essential part of the essential.

The following is a common marble pill formation and treatment methods

First, the marble columns lesions rust stains rust

Formed from two aspects: First, the natural reaction generated. Because the material inside the marble columns contains hematite and pyrite, the iron mineral contact with the oxidation of oxygen and the formation of iron oxide (rust), through the marble columns cacolumnsy leakage; the second is because the marble columns in the mining, processing, transportation, installation, use and other processes, the inevitable access to iron items, the residual iron objects dip in the marble columns surface, was oxidized after the formation of rust pollution. The key to the prevention of rust marks is the marble columns before the installation of resin must be used to make the marble columns with a waterproof function to prevent the marble inside the iron mineral is oxidized after the marble columns surface. After installation must thoroughly clean the marble columns, to prevent the marble columns due to external pollution caused by rust marks. In the construction method as far as possible the use of dry hanging way, especially as a kind of American white linen and other more prone to rusty marble columns, should avoid the use of wet construction methods, if necessary, before installation can do a full range of rust and waterproof deal with. 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 is the rust after the marble columns will not rust; Corrosion of marble columns, does not affect the marble surface gloss. However, because the rust is acidic, so in the marble (calcium marble columns) rust in advance to do the experiment, it is necessary to add water to dilute. In the rust, thoroughly cleaned with water, and then protective agent for protection, so that the marble columns with a waterproof function to prevent the occurrence of other lesions in the future and due to chemical corrosion caused by the trouble.

Second, the Marble columns lesions wet mark quit

The main reason for the formation is due to the influence of the cement mortar in the wet construction method. Because the composition of the cement contains 1% to 2% of sodium hydroxide, due to its strong adsorption of water, in the humid atmosphere when the ambient temperature is higher than 35 degrees, immediately form a corrosive sodium carbonate solution. Crystalline water often changes due to changes in temperature, but will never be scarce, which formed a wet mark dry phenomenon. The main method of prevention is to protect the marble columns, so that the marble columns are waterproof, so as to block the moisture in the air and the marble columns or cement internal material contact, reduce its chemical reaction conditions; Secondly, should try to avoid the use of cement construction Installation of materials; and finally to do a good job sealing works and drainage works. Processing has been the emergence of wet marks, at home and abroad there is no effective way. The main remedial action is to use the resin injection method so that there is no wet mark parts of the color deepened, in order to adjust the color difference between the two.

Third, the Marble columns of the salt crystallization

This phenomenon is mainly due to the strong alkaline cement and the atmosphere of the acidic solution from the reaction. Sodium carbonate solution through the pores of the marble columns to the marble columns surface, and immediately with the moisture containing carbonic acid to neutralize the reaction to produce salt solution, the solution of water dry, the formation of salt crystallization. In case of water dissolution on a large area. Prevention First of all, to avoid the use of wet construction methods, followed by protective agent to make marble with waterproof performance. And do a good job sealing work. The method of treating salt crystals is simple. First brush the marble columns on the surface of the white powder brush off, and then a lot of water to thoroughly clean the residue, and finally the protection or in the marble columns surface with a waterproof performance of the polishing agent can be polished.

Fourth, the Marble columns lesion lime denudation

This phenomenon from the carbonated lime solution has not penetrated into the external wall surface, and the atmospheric reaction of carbon dioxide, easy to produce easily hydrolyzed calcium carbonate, as a layer of permanent coating.

This phenomenon occurs mainly in the marble columns seams. In dealing with the phenomenon of lime erosion, it is necessary to dissolve the calcium carbonate with acidic solution, and then thoroughly clean the marble columns with water, and finally the use of waterproof resin for injection, in order to prevent the lime solution re-oozing.

Five, frost damage

This phenomenon is mainly due to the marble inside the pores and cracks absorbed by the cold water caused by cold. Because the liquid water after the ice volume expansion rate of about 10%, so that the marble columns inside a lot of pressure and swelling of the marble columns. Some of the porous marble columns are more likely to happen. Preventive measures are to make the marble columns waterproofing to reduce the moisture content inside the marble columns.

Six, the growth of bryophytes

The phenomenon mainly occurs in the marble columns internal moisture and organic matter content of high parts, it will lead to marble disc discoloration, reduce the strength and service life of marble columns. Preventive measures First of all, to do the drainage works to avoid water; coupled with the application of protective agent, so that the marble columns with good water resistance. The emergence of moss should be the first tool to eradicate it, and then clean the professional cleaning agent, the best marble columns to do the protective treatment, waterproof and improve the original drainage facilities.

Seven, chemical corrosion

This is due to industrial waste gas plus car exhaust emissions, so that the air sulfur dioxide and sulfur trioxide content of the reasons for the sharp increase. Dissolved in water to form an acidic solution, can easily dissolve the calcium carbonate in the Marble columns, causing chemical corrosion. Prevention is done before the construction of the marble columns waterproof, to prevent these harmful solutions into the marble columns. In summary, these problems arise from the fact that harmful ionic solutions are free and free through the pores of the marble columns. In this process, water becomes the main carrier of these harmful substances and participates in the chemical reaction of harmful substances. So the main treatment of the Marble columns is waterproof treatment.
