1. Pay attention to waterproof
The causes of stone pollution can be roughly divided into the following four categories:
1. Organic substances such as cigarette stains, soy sauce stains, and iodine stains;
2. Metal stains such as iron rust, steel rust, lead rust;
3. Oil stains such as gasoline, engine oil, paint;
4. The easiest to present and the hardest to prevent are water stains.
Under normal conditions, the water stains will evaporate within a certain period of time, but under the condition of high underwater temperature, the water stains may not disappear but will be immersed and stored in the stone for a long time. Various stains (except liquids) will not affect the stone itself. As long as the stains encounter water and produce chemical changes, they will cause problems such as staining and pollution. In addition, water immersed in the stone will also change the quality of the stone. The mineral salts in the stone will have a chemical effect due to contact with water. When the crystals gradually become larger, the stone surface will explode and crystals will precipitate, forming white flowers and other pollution. problem. Therefore, it can be concluded that water is the biggest enemy of stone, and this problem can be basically solved as long as the stomata of the stone are blocked.
The famous saying “Prevention is better than cure” is the most appropriate for stone. The purpose of stone conservation is to “avoid water infiltration and let water breathe out”. According to different characteristics, the stone protective agent provides comprehensive maintenance to the stone, resists the penetration of water, stains, oil stains, etc., and also prevents mineral salts from being carried out of the stone, causing white blooms or rust stains.
2. Do not cover up carpets and debris for a long time
In order to maintain the smooth breathing of the stone, it is necessary to prevent the carpet and debris from being covered on the stone surface for a long time, otherwise, the moisture under the stone cannot volatilize through the pores of the stone. The stone will cause annoying stone pathological problems due to excessive moisture and increased water content. If you must lay carpets and pile up debris, please don’t forget to change it frequently.
3. Don’t wax at will
There are many kinds of wax on the market, including water-based wax, stearic acid wax, oily wax, acrylic wax, and so on. These waxes basically contain acid and alkali substances. Not only will it obstruct the pores of the stone’s breathing, but it will also be stained with dirt and wax to form a yellowing phenomenon on the surface of the stone. When waxing is required in places with a high frequency of pedestrians and goods circulation, it is necessary to consult a professional nursing company for guidance on waxing and nursing.
4. Do not use non-neutral detergents indiscriminately
In order to achieve a quick cleaning effect, common detergents contain acid and alkali. Therefore, if the detergent of unknown composition is used for a long time, the surface gloss of the stone will be lost, and the residue of non-neutral agents is also the main cause of stone disease in the future.
5. Do not touch non-neutral items
All stone is afraid of acid and alkali. For example acid often forms pyrite minerals in the granite that oxidize to produce yellowing, the acid will synthesize calcium carbonate contained in marble, forming a situation where the surface is corroded, and alkali will also corrode granite feldspar and quartz silicification The grain boundary of the material crystal forms the phenomenon of crystal grain exfoliation. Therefore, non-neutral items are the original culprit that destroys the stone mirror surface.
6. We must thoroughly adhere to cleanliness
Both hard granite (hardness HRs88-111±4-7) or soft marble (hardness HRs46-77±3-5) are not resistant to long-term trampling by wind sand and soil particles.
Therefore, dust collectors and electrostatic mops should be used from time to time to thoroughly remove dust and clean. It is best to place dust-removing mats at the entrance of commercial spaces to filter out the sand in the shoes. For homes, it is best to change into slippers after entering the entrance to reduce the chance of sand and dust abrading the surface of the stone.
7. Regular maintenance and maintenance of gloss
Dust removal and cleaning alone cannot make the bright stone luster persist. Therefore, you must regularly ask a professional company to send someone to do maintenance work for maintenance and gloss regeneration.
In the past, wax was often used for stone maintenance, which was not only time-consuming, labor-intensive, and expensive, but also was an ammonia-containing substance. After volatilization and synthesis, the wax had a negative impact on the human body and the environment. It has been gradually discontinued internationally. At present, crystal face treatment is the best way to maintain.
8. Always keep ventilating and dry
The stone is afraid that the environmental humidity is too high. Moisture will produce hydration, hydrolysis, and carbonation of stone, produce water spots, bleaching, weathering, denudation, rust yellow, and other diseases, and destroy the stone. Therefore, the stone installation place should always be ventilated and dry.
9. Be aware of pollution immediately
All stones have natural pores, and pollution sources (oil, tea, coffee, cola, soy sauce, ink, etc.) will easily penetrate into the stone along the pores and form disgusting stains, so you must choose excellent quality stone Special protective agent is used for construction to avoid pollution sources on the stone surface from polluting the stone. It should be understood that all protective agents cannot prevent pollution 100% for a long time, so once a source of pollution is poured on the stone, it must be cleaned immediately to avoid infiltration into the pores of the stone.
10. Protective measures must be implemented on a regular basis
To maintain the life of the stone for a long time and prevent the infiltration of water and pollution sources, professional protective measures must be taken on a regular basis. Special attention must be paid to the quality of the protective agent. After construction, it must be able to maintain the air permeability, water resistance, and antifouling properties of the stone. Never use protective agents of unknown origin, lest they not only fail to achieve the protective effect but increase the disturbance of stone maintenance.
