Renovation and crystallization
(1), the ground is dry - this process is divided into two cases, 1 the original stone surface joints of water stains, we use far infrared light heating and drying. 2 Other flat moisture, dry naturally. As a result, the water stain phenomenon has been completely removed, which is economical and reasonable, and the customer is very satisfied.
(2) Filling the stone joints - It is an important preventive measure to solve the water penetration of the stone joints by caulking. It is necessary to pay attention to the work of caulking. The caulking material should have good adhesion, no powder, waterproof, and can be ground and polished. We use German super marble crack repairing agent to fill the gap according to the process (filling the surface with the stone plane, the caulking should be even To prevent omissions.) After more than two hours of drying and curing.
(3), leveling grinding and polishing - in view of the stone surface previously made waterproof, resulting in stone discoloration, we did not directly use the method of leveling grinding, but first with O# steel wool, with special equipment for grinding, grinding, grinding The color-changing layer on the surface of the stone reveals the original background color of the large white flower. Fortunately, because the degree of penetration of the protective agent into the stone surface is very light, we have only received good results with the above scheme, and the problem of discoloration that we are worried about has been treated. The second solution is to use marble diamond grinding discs, water-grinding discs, and grinding and polishing step by step.
(4), rust yellow treatment - according to the overall plan, first place on the rust spots, with steel wool to remove the surface rust, and then use a special marble rust remover for rust removal. The rust removal process is as follows: clean surface, dry rust surface, white paper towel, rust remover, plastic film, sealing surface, aging treatment, aging for 3 hours, after washing with neutral detergent, dry with water (dry rust can not be removed) Trace can be reprocessed)
(5), waterproof, protective - in order to avoid marble water, rust, and other pollution in the future, the customer is interested in our plan, to protect the ground after grinding, we learned the original protection discoloration lessons, choose several A better waterproofing agent, taking the same stone to do the experiment, on the one hand to check the protective effect, on the other hand to check whether the color of the stone is changed, and to determine the amount of the process according to the water absorption rate. After doing the above preparations, we have protected the ground on a large scale. Protective treatment We mainly focus on the following processes: 1 clean the stone surface. 2 fully dry. 3 Evenly apply protective agent, moisturize the stone surface, do not leak the brush, not too much, prevent accumulation, the former affects the protective effect, the latter affects the appearance and increases the difficulty of cleaning. 4 Under natural conditions, ventilate and dry for more than 24 hours.
(6), crystal treatment: After the above process, crystal treatment can be carried out, we use the Spanish crystal hardener, the light agent according to the use of the process description, through the equipment pressurization, low-speed grinding, the heating of the agent The reaction causes the ground to form a non-slip hard mirror.
Treatment of water seepage and pollution of stone exterior wall
As the building is at the pivot, 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 sandstone surface. A layer of wax can be applied to the sandstone, but the treatment of the wax should be paid attention to.
Stone conservation
As the name suggests, it refers to the maintenance and protection of stone.
Protective stone refers to the application of wax or protective agent on the stone to protect the stone from the external environment. Maintenance of stone refers to cleaning stone pollution, controlling stone diseases and stone glazing.
Wax is a kind of stone protectant which is usually used more. Now most of the domestic waxing is used to protect the stone, but the wax is an airtight sealant. After the wax is finished, the outside water and moisture cannot enter the stone interior. However, the moisture inside and below the stone can not be emitted, and it is accumulated inside the stone, which will cause stone lesions. At the same time, as the number of waxing increases, the color of the stone will be deepened, and the wax is easily contaminated, forming wax scale. Cleaning is very inconvenient, and only the old wax can be solved again, and waxing often damages the surface of the stone. Now Europe, the United States and Japan, basically do not use waxing to maintain stone. Most of them use an advanced high-tech product - osmotic protective agent.
The osmotic protective agent can be divided into two kinds of solvent and water. The protection principle is that the effective substance penetrates into the interior of the stone with the solvent. After the solvent is naturally volatilized, the effective substance remains in the interior and surface of the stone to form a protective barrier to prevent external pollution. Infiltration, to prevent the pollution of the inside and the bottom of the stone, so as to maintain the original appearance of the stone and extend the life of the stone. The solvents of solvent-based protective agents are highly volatile, flammable, pungent and toxic, so they should be well ventilated during construction. Water-based protective agents are environmentally friendly protective agents, colorless and non-toxic. It is tasteless, does not burn, and has no effect on the environment.
No osmotic protective agent can form a protective layer on the surface of the stone. Therefore, the softer stone surface will be worn after being protected. In order to improve the wear resistance of the stone, a surface protection treatment can be done on the surface of the stone. It is commonly used in foreign countries as a surface protective agent. It is a kind of protective agent that can be “breathedâ€. It not only protects the stone, but also maintains the natural bright color of the stone.
Post-maintenance of stone
The post-maintenance of stone is also very important. In order to keep the stone bright, careful maintenance is necessary. It includes three aspects of daily cleaning, pollution removal and glazing. Daily cleaning can be done with clean water or some neutral detergents. After cleaning, the surface must be wiped dry to avoid contamination caused by residual moisture and damage the luster of the stone. Daily cleaning can only clean some surface dust and dirt. If you encounter some special pollution such as plant pigment pollution, oil stains, rust, etc., you must use a special cleaning agent to remove. If the surface is not very shiny or scratched or even tarnished, the stone should be glazed or polished. There is a special syrup on the glazing. After smearing, the polishing opportunity increases the brightness, and the wear resistance of the stone can also be improved. Grinding depends on the degree of damage of the stone. The lighter is hand-polished with the syrup for polishing. In the case of heavy, the grinding machine is used with a special agent to restore the original luster.
In order to maintain its beautiful appearance for a long time, in addition to reasonable installation, natural stone should be protected, cleaned and routinely maintained. I believe that after such maintenance, your stone will definitely improve the life and value of use.
