(Summary description)    Whether it is new stone or refurbished stone, with the normal use and time, the wear of the stone will become more and more serious and its gloss will be lower and lower.

Timeliness

    Stones must be maintained in a timely manner through timely maintenance. If the gloss reduction exceeds the maintenance recovery capacity, the recovery level cannot be achieved.

    The correct maintenance method is to adopt the maintenance process in time before the decline of the gloss of the stone does not exceed the recovery ability of the maintenance measures. After the maintenance is completed, the gloss recovery can basically reach the original level, so that the stone remains durable for a long time, which is ideal. status of use.

Due to its natural formation characteristics and the accompanying of various forms of wood, the stone determines that it will cause lesions and weathering damage in its environment, which is caused by its internal cause. On the other hand, the deterioration of the use environment such as acid rain, pollution, moisture, etc. is also the main cause of various problems and lesions in the stone. The consequences of these problems and lesions are serious. From the natural weathering damage of ancient stone artifacts to the various natural damages and lesions of today's architectural stone, the damage caused is enormous. Then, how to effectively prevent this and maximize the avoidance and control of these damages and lesions become more and more important. Waxing has been widely used as a way to protect stone. It is mostly used on the paved stone floor. However, its protective effect on stone is limited, the weather resistance is poor, the antifouling effect is not ideal, and dust is easily attached. Nowadays, people also find that waxing also causes some harm to the stone, because it is applied as an airtight cover protection material on the surface of the stone. After the pores of the stone are closed, the moisture inside and behind the surface is not released. In the interior of the stone, the stone has been damaged for a long time. There is also a liquid wax water that is usually applied to the inner wall surface. This is a film material, and its main disadvantage is that it affects the natural texture of the stone. The emergence of osmotic protection products is a major advancement in the development and research of stone protection products, but the application time in our country is not very long. This kind of product is mostly solvent or water medium, bringing some effective waterproof materials to the inside of the stone. Form a deep protective barrier that shuts off water and some liquid contamination. This kind of permeable protective product not only changes the natural texture of the stone, but also maintains the permeability of the stone. Its performance is superior and scientific and reasonable. However, due to the difference in materials, some products will have different effects on waterproof, antifouling and oil repellent effects, but most products work better.



For the selection and use of stone protection products, in addition to understanding the product performance, we must also pay attention to the following points:

(1) Compatibility. Choose a product that has no effect on the color of the stone. If it is wet-laid construction, it should be checked whether it will affect the adhesion between stone and cement when it is treated on the back of stone.

(2) Under the condition of wet sticking construction, it is necessary to do a good job of treating the back and side of the stone, then focusing on selecting a protective agent with good waterproof effect.

(3) In addition to the waterproof treatment of the back surface, the front side of the stone should be properly protected according to the use environment. Some special places, like hospitals, must choose products with good anti-fouling performance. For hotels, they must choose anti-pollution and anti-oil protective products.

(4) The significance of dry-hanging stone for the protection of the back side is not significant. For the front side, the corresponding protective products can be selected according to the use environment and the characteristics of the stone.

(5) For stones that are prone to lesions, like some grayish white granite and marble, often rust or spit in wet conditions. It is important to do waterproof treatment, and the protective agent should have excellent waterproof effect.

(6) For granites with high water absorption and high water absorption, use them in public environments. Be sure to choose products that are waterproof, anti-fouling and anti-spray, so that they can be easily cleaned once they are contaminated.

Common cleaning agent
 
 
 
(1) Marble cleaner
 
This is an acid-free neutral stone cleaner, which is very suitable for dirt, wax, oil and glue on marble. Cleaning of paint and other building dirt. It does not damage the surface and luster of the marble, nor does it damage the marble.
 
 
 
(2) Granite cleaning agent
 
This cleaning agent can effectively remove the surface and cracks of granite and the dirt, dust, building dirt, glue, oil stains and stains in the sand, it will not damage the surface and luster of granite. .
 
 
 
(3) Granite to rust
 
The rust remover can effectively remove rust and rust spots on the surface of the stone due to internal factors and foreign rust contamination. It restores metal oxides to the original metal components and creates a protective barrier against rust.
 
Discoloration
 
The color change of stone mainly appears in the stone variety with poor chemical stability. The place where the indoor is not exposed to ultraviolet light is discussed here, and the color of the light stone of the stone dry hanging process becomes darker. The typical case is that the white travertine (travertine) appears in the process of installation. The stone wall gradually turns yellow from top to bottom. Over time, the entire wall completely turns yellow. The chemical stability of travertine itself is poor. Carbon dioxide, sulfur dioxide and nitrogen oxides in the air react with calcium oxide in travertine. In particular, the sulfide formed must be yellowish white stone. Moreover, both the coating and the binder contain a large amount of volatiles during the construction process, and these volatile components also react with the stone to affect such stones with poor chemical stability.
 
 
 
Organic pollution
 
    When the stone is contaminated by organic matter, the color of the contaminated part will be deepened, and it will not fade for a long time, and it will absorb dust. Organic pollutants are mainly derived from oil and animal contact, especially where humans often touch them by hand. In fact, often in the most conspicuous places, the finest place to decorate the stone is also the place where human contact is the closest. Such as stair railings, generally decorated with special-shaped high-grade marble. The least suitable is the use of white marble sculptures in public places as a decoration, the material can be imagined after such a situation has been contaminated.
 
 
 
    Inferior organic sealant can also cause pollution of dry-hanging stone curtain wall. On the one hand, it will be dip-dyed on the edge of stone-sized sheet, and on the other hand, it will adsorb dust in the air.
 
 
 
Rust
 
The causes of rust spots can generally be divided into two types:
 
 
 
    The first type of rust is caused by the iron contained in the stone itself. Generally speaking, each stone itself contains iron components. When the rainwater comes into contact with the iron in the stone, it will gradually form rust spots. This rust spot is difficult to remove and takes a long time to process. Kelin KL608 strong rust remover can be used. It has strong permeability and can penetrate deep into the surface layer of stone to ensure the thoroughness of cleaning. It can effectively remove rust spots and not harm stone. Avoid using industrial hydrogen peroxide or other corrosive strong acid. Otherwise it will be self-defeating. The most important thing is how to prevent the regeneration of rust spots. The most effective method is to prevent the rust and then prevent it from re-infiltrating into the stone to avoid the regeneration of rust spots.
 
 
 
    The second type of rust is foreign, such as steel grit remaining during processing or iron during construction, metal parts for decoration, etc. This rust is easier to remove, and the KL308 rust remover can be used. In general, it is quite difficult to completely remove the rust after the stone is produced. Therefore, the protective treatment before the installation of the stone is better than the protection after the completion of the work, because the external wall has a considerable height after completion, the construction is not easy, and there is also the possibility of contact with acid rain during the installation of the stone, so the protection before construction is The best is rust and dirt.
 
 
 
Water seepage
 
    Because the building is in a pivotal position, the relative pollution is particularly serious. Because the stone itself has capillary pores and water absorption, air pollution, dust plus acid gas in the air, exhaust gas of the steam locomotive, etc., accumulate on the surface of the stone over time, when it rains, acid rain will accelerate the erosion of these stones on the stone. Adsorbed in the capillary pores of the stone, causing stains that are difficult to clean. Especially for the stone that burns the surface, these pollutions form faster and are not easy to clean. Only using commercially available cleaning agents can not remove these pollutions; If it is a smooth stone, these luster will soon be eroded.
 
 
 
    Therefore, in order to remove these pollutions, stone cleaning agents can be used. The special cleaning agent for such stones can completely remove the contamination that penetrates into the pores and does not harm the stone. If it is necessary to prevent the stone from being contaminated again, after the stone is cleaned, under the condition that the surface of the stone is dry, a protective treatment work can be carried out. The permeable protective agent can penetrate into the interior of the stone to form a protective layer. It has the effects of waterproofing, anti-fouling, anti-fouling, anti-rust, anti-oil, anti-weathering, anti-aging, acid and alkali resistance, tea stain, cola, soy sauce, etc., and can effectively control the production of Baihua. And does not damage the original permeability of the stone, the usual cleaning work can be achieved by simply wiping with water, without using other cleaning agents.
 
 
 
    Pre-protection treatment of external wall pollution: Generally speaking, the outer wall of stone has a considerable height. Once it is contaminated, it will be cleaned and the construction is extremely inconvenient. If the protection can be done beforehand, there will be no pollution problems after completion. The daily cleaning work can only be wiped with water, and the protection cost before construction is low, the construction is easy, and the stone protection agent is used. This breakthrough has improved the time-consuming and laborious troubles of the previous protection treatment, which has been widely used in stone engineering abroad.
 
 
 
Water spot
 
    After the stone is finished, it will not dry for a long time and always have wet traces on the surface. This is commonly known as water spots. The reason for the appearance of water spots is very complicated. Some scholars believe that the water absorption rate of stone is high, the stone protection is not done well, the atmospheric precipitation or the water seepage of the building is immersed in the interior of the stone, causing the stone to be in a state of water saturation, thereby forming a water spot. Specific problems should be specifically treated. If there are water leaks in some parts of the building, such as long-term flooded toilets or water rooms, leaking pipes or rainwater pipes, this is in line with the above viewpoint. The problem is that water spots are common in the walls of buildings that are not water-rich environments or on the floors of high-rise buildings. This phenomenon cannot be explained by the above viewpoints. This requires some means to analyze the water spot components. Analyze and analyze the source of the ingredients to find the root cause of the formation of water spots and treat them in a targeted manner. It can be said that water spots are the most common disease encountered in the stone application nursing industry. It is also the most complicated problem, the most difficult to manage, and the problem that needs to be solved in the future.
 
To remove water spots, it can be said that it is very difficult, because the formation of water spots is very complicated, including cement, acid rain, white, bad sand, and the pollution of stone from the ground, which causes the deterioration of the stone itself. This kind of stone is not easy to clean, so the only way to prevent water spots is to prevent it. To prevent the formation of water spots, stone protectants can be used before construction. Before the construction, the stone is treated to prevent the formation of water spots, and at the same time, good anti-fouling effect can be achieved.
 
 
 
Baihua
 
    Baihua is a phenomenon of white powder or sag on the surface of stone or in joints. It often occurs outdoors or where there are abundant water sources, such as flower terraces, outdoor steps, and external wall caulking.
 
 
 
    When the stone is installed in a wet manner, the alkaline substance such as calcium hydroxide in the cement mortar is backed up and dissolved by a large amount of water to penetrate the surface of the stone or the place where the joint is not filled, and the calcium hydroxide and the carbon dioxide in the air Or the SO2 sulfuric acid compound in acid rain reacts to form calcium carbonate or calcium sulfate. When the water evaporates, calcium carbonate or calcium sulfate crystallizes to form white Hua.
 
 
 
    The factors that form Baihua in stone are similar to those in water spots. A large amount of water and alkaline metal ions are the causes of Baihua. Among them, water plays the role of a destroyer, which dissolves alkaline metal ions and then penetrates into the surface of the stone by capillary phenomenon. If the caulking is not true, Baihua will be further formed. Therefore, to prevent the penetration of moisture and alkaline metal ions to the surface of the stone or the unfilling of the joint, the occurrence of Baihua can be prevented.
 
 
 
The measures to prevent the formation of Baihua are as follows:
 
    The stone should be applied for protection before installation (front, five or six sides, depending on engineering requirements) to prevent the stone from inhaling too much water and prevent cement mortar from the front of the stone or the groundwater source from penetrating into the stone to avoid cement mortar. The alkaline metal ions penetrate into the stone, causing Baihua.
 
 
 
    Use a gap-filling material suitable for stone and apply it according to the correct construction method. Good quality joint filler material and correct application method can prevent the occurrence of Baihua in the joint.
 
When blending cement mortar, use low water ash ratio or add water reducing agent. Reduce the excess water to avoid the occurrence of a white.
 
 
 
The waterproofing agent is added to the cement mortar to prevent the metal ions from being dissolved and oozing out of the surface of the stone to form white hua.
 
 
 
    Use non-polluting aggregates, such as avoiding the use of sea sand with more calcium, magnesium, sodium and other ions, and avoid using groundwater with more minerals as mixing water, reducing the source of metal ions and reducing the chance of occurrence of Baihua.
