Stone maintenance knowledge: Marble mirror treatment technology


Renovation of stone
Stone is widely used as paving material. The noble, elegant and light decoration effect is deeply loved by people. However, due to improper installation and use, or over a long period of time, there will be seam cutting, irreversible surface pollution, and wear and loss of gloss. At this time, it is necessary to re grind the stone to a smooth, bright and clean surface, which is what we call renovation.
The main mineral components of marble are calcite, dolomite or serpentine. The Mohs hardness is between 3-5 degrees and the shore hardness is between 35 and 55 degrees. The wear resistance and luminosity of granite are relatively lower than those of granite. Therefore, the possibility of renovation is large, the difficulty of renovation is small, and the cost is relatively low. The key of marble renovation is to improve smoothness and luminosity. Machines, abrasives, operation, these three points should be organically combined, and should be adjusted in time according to the ground conditions of different stone varieties, in order to achieve the desired effect. ?


The principle of crystal hardening of marble floor
Marble as a building decoration material, beautiful and elegant, deeply loved by people from all walks of life. However, they are mainly composed of calcium and magnesium. For example: some marbles mainly composed of calcite have a Mohs hardness of only 3 degrees. Therefore, when it is used on the ground, the wear resistance is obviously lower than that of granite composed of feldspar and quartzite, and it is easy to lose luster and be polluted and eroded. ?
The traditional maintenance method of marble floor is to make a layer of wax film containing resin on the ground to separate the friction of absolute marble. But at the same time, it also brings some weaknesses such as poor texture and cumbersome post care. ?
The crystallization hardening method avoids the weakness of the above methods. Chemical drugs such as "Hanoi" series or crystal hard powder of the United States are used to change the quality of the marble surface layer with the help of the pressure and temperature generated by mechanical friction to generate new mixed crystals of calcium carbonate, Zheng oxalate and calcium silicate (magnesium) (carbonate, oxalate, silicate), so as not to change the stone pattern The hardness, luminosity, density and skid resistance were improved. This method has a longer maintenance period. For example, it should be done once every three months under normal circumstances, and it can be done once half a year or even longer if the flow of people is small.

Maintenance
1) waxing
① Waxing method: firstly, clean the floor, dry it with air dryer, and then polish the bottom wax, surface wax and polishing wax. ?
② Function: easy to clean, protect stone, prolong service life, anti slip, etc. ?
2) mirror surface treatment: after renovation
Treatment method: use physical and chemical methods to soften the crystal lattice of stone surface, and form a dense molecular arrangement layer under the mechanical grinding pad
The crystal lattice is solidified again. ?
② Function: increase hardness, brightness, easy to clean and prolong service life. ?
3) renovation
If we don't get proper care, the original natural color and luminosity of the stone surface will gradually lose, and it is easy to hide dirt and dirt, which makes people unbearable. For example, the cost of repaving is high and time-consuming. Therefore, renovation and maintenance are taken seriously. ?


① The method of polishing and polishing the surface of the stone surface to make it smooth and free of scratch. ?
(Note: this method is limited to terrazzo, marble and granite.) ?


② Function: make the stone surface which lose original luster and luminosity restore the original beautiful and shining decorative effect. ?
Its waterproof and impermeability make sewage and all kinds of stains can not penetrate into the stone surface
