Stone flooring, like our faces, is prone to aging if we don't pay attention to maintenance, and it can also lead to alkalinity, yellowing, rust, and yellowing. So, do you understand why stone needs to be maintained?
Why do stones become diseased
Stone itself has a natural and prominent physical characteristic - water absorption (usually granite has a water absorption rate of 0.1-0.2%). Due to unreasonable stacking, packaging, transportation, and contact with external pollution sources such as water vapor, rainwater, oil, etc., stone materials are prone to pollution. The pollution problems that users often encounter include: pan alkali, rust spots, yellow spatter, stains, oil spots, straw rope yellow, weathering, aging, fading, gloss wear, etc. In addition, the problems that our construction personnel often encounter during construction, such as water spots not drying and watermarks appearing after wet stone pasting construction, are common problems in engineering and are also one of the main reasons for engineering disputes.
Let's first talk about the inherent factors of stone itself:
1) The natural micropores in stone: Without discussing the principles with friends, it simply means that the stone will breathe, and if water is accidentally sucked in, it can easily cause multiple problems, such as water spots
2) The relatively complex chemical composition of stone: Each type of stone has a different chemical composition, which leads to chemical reactions with external substances, such as the direct relationship between the iron content of stone and rust yellow spots
Cough! Let's talk about external factors again, yes, they are favorable timing, location, and people:
1) The mediating effect of water: It is also water. I don't know if friends have noticed it. Many stone lesions are caused by water, so we must ensure the dryness of the stone
2) The infiltration of pollutants mainly includes: pollution of water-based liquid substances (such as tea, coffee, cola, soy sauce, soup, etc.); Organic substances (such as wood, straw, cardboard boxes, cigarettes, etc.); Oily or oil-soluble substances (such as engine oil, edible oil, gasoline, solvents, tar, etc.); Adhesive materials (such as paint, markers, ink, toner, crayons, dyes, inks, etc.); The transfer printing of colored materials (such as colored cloth, colored paper, bleached clothing, etc.) can cause pollution or even damage to the stone material.
3) Chemical and biochemical reasons: some pollutants will be accompanied by obvious chemical changes and chemical erosion. Some organisms also secrete acidic substances that easily absorb certain minerals in rocks, causing biological erosion from the surface. Rust solution such as sawdust, iron tools, welding sparks, etc; Environmental pollution and acid rain erosion can also cause pollution and corrosion to stone materials.
4) Erosion and weathering of natural environmental conditions: The impact of dry and wet cycles on stone, day after day, year after year, changes in air and surrounding environmental humidity, cause frequent wet expansion and dry shrinkage of stone. The cold winter causes ice to form inside or around the gaps in the stone, resulting in expansion and freeze-thaw effects. Salinity, sandstorms, and other factors can cause destructive erosion of stone materials.
5) Improper cleaning and care methods and poor management: This is also human factor damage to stone, mainly reflected in the pollution of expansion agents, explosives, iron sawdust, engine oil, etc. used during stone mining and processing; There is also damage to stone caused by improper methods during transportation, installation, and use
