Stone is also a building material often used in interior decoration, such as floors, walls and tables. At present, the probability of using stone in decoration is relatively high. In order to keep the stone in a novel state, it needs maintenance. Different materials of stone maintenance methods will be different. If you don't know the maintenance method of stone, you can look at the daily maintenance skills of stone.

I. Maintenance of Stone Materials with Different Materials

1, marble. Its main components are calcite and calcium carbonate, and its Mohs hardness is about 4.5. Soft quality, acid and alkali resistance, poor weather resistance. Easy to absorb oil, water and other liquids, easy to be scratched. The best protection of polished marble is to use permeable waterproof and oil-proof protective agent for pre-protection before marble is put into use. Use neutral detergent instead of acidic detergent for daily cleaning.

2. artificial stone. It is made of 7-meter-long natural logs of different specifications as aggregates. Add organic (resin) or inorganic (cement) polymer materials. Made of scientific formula, the average flexural strength should not be less than 5. OMPa, and the minimum value of each block should not be less than 4 OMPa, which is suitable for the ground, stove and other places. Neutral or weakly alkaline cleaners can be used for daily maintenance.

3. limestone. Its main component is calcite, which is soft in texture, easy to absorb oil and other aqueous liquids, easy to be scratched and corroded by acidic substances, and more susceptible to pollution than marble. Most limestone is porous and absorbent. Some limestones are semi-metamorphic rocks with the same physical properties as metamorphic marble. It can be used to pave the road. It is suggested that the limestone surface can be cleaned with neutral detergent after being treated with osmotic protectant.

4. granite. Mohs hardness is about 6.5, and it is mainly composed of quartz (35%), feldspar (45%) and potassium, and its color is usually dark. Some of them also contain very small amounts of calcite. Granite has strong acid and alkali resistance and wind resistance because of its high hardness. But its surface also has pores, which are easy to be polluted, but the water absorption effect is not bad. . It is suggested that osmotic protectant should be used for pretreatment first, and neutral or weakly acidic cleaning agent should be used for daily cleaning.

Second, the daily maintenance skills of stone materials

1. Always keep it ventilated and dry.

Stones are afraid of being too wet. Water vapor will hydrate, hydrolyze and carbonate stone, resulting in water spots, whitening, weathering, denudation, rust yellow and other diseases, which will cause damage to stone. Remember to keep it ventilated and dry when installing.

2. Stone curing is most afraid of washing directly with water.

If the stone absorbs too much water and is polluted, it will inevitably cause various stone diseases, such as cracking, weathering, falling off, floating, yellowing, water stains, rust spots and white flowers, so the stone should avoid washing the stone surface with water or a wet mop. Even if excellent stone protectants are used, it is impossible to completely block water and pollution for a long time, so the lesions caused by water pollution should be treated immediately.

3. Stone curing is most afraid of covering sundries for a long time.

In order to keep the stone breathing smoothly, it should be avoided to cover the stone surface with carpets and sundries for a long time, otherwise the water inside the stone can't evaporate through the pores of the stone, and the stone will get sick because of too much water and increased water content. If carpets must be laid and sundries piled up, the stone surface must be thoroughly kept clean, and dust removal and cleaning should be carried out from time to time by using dust remover and electrostatic mop. Neither hard granite nor soft marble can withstand the long-term ravages of sand and soil particles.

4. Don't wax at will

There are many kinds of waxes in the market, such as 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 block the breathing pores of the stone, but it will also be contaminated with dirt and dust to form wax scale, which will lead to the yellowing of the stone surface. However, if people and articles must be waxed in places with high circulation frequency, you must consult a professional maintenance company for waxing maintenance guidance.
