Chengdu Stone Renovation Company Basic steps of grinding renovation and crystallization curing treatment Chengdu Stone Renovation Company Stone protection construction operation before polishing:
1. The stone shall be caulked with marble sealant with a color similar to that of the stone surface;
2. The stone surface shall be coated with protective agent and polished for more than 4 hours.
5、 Refurbishment grinding
Refurbishment procedure:
According to the degree of stone wear, it can be divided into light/shallow renovations, high-rise renovations, etc. In fact, the new stone surface has been kept crystal hard since it was used, and the stone surface can always be kept intact. even if door Slight wear and tear may occur at places where there are many people in the middle, and light/light renovations only need to be carried out once in a while, while high-level renovations are only used on stone surfaces that have been out of maintenance for a long time.
Special attention: refurbish the water grinding disc or Abrasive block It must be grinded from coarse to fine in order, without wrong number and skip number; There should be enough water when grinding, and each process must remove the grinding marks left by the previous one; At the same time, each process must completely remove the powder left by the previous process. Marble The special use of marble abrasive disc (thin disc) and granite abrasive disc (thick disc) shall be used. The principle of "hard to hard, soft to soft" shall be kept in mind.
High level renovation: the stone surface has been out of maintenance for a long time, and has been severely worn. If the scar exceeds 0.5mm, the high level renovation should be carried out, generally under the guidance of professionals.
Operation sequence: basically the same as light renovation
Special situation: if the quality of stone surface installation works is too poor, there is a serious uneven phenomenon between stones, even new stones need to be renovated at a high level. The height difference of the shear is not more than 0.5mm, and it can be directly renovated at the high level. If the height of the shear exceeds 0.5mm, use your hand first Mill Polish, or use a metal plate to polish the shear opening, and then conduct high-level renovation; The operation is the same as cutting.
Stone surface maintenance of wall body and small platform corners:
Since large stone care machines cannot be used in these places, direct manual processing will reduce efficiency. The better way is to use a portable polishing machine with marble polishing agent or directly apply stone polishing wax! When renovating, there are some places that cannot be reached by machinery, such as walls and corners. The overall consistent effect can be obtained by using diamond hand sharpening; In addition, it is simpler to directly spray the stone surface with the stone care spray agent, which is better to use with the steel wool.
6、 Crystal face treatment
Crystal surface care is an effective, better and more economical way to maintain marble, and will not damage the stone surface.
Crystal face care agent is not wax, polishing powder, nor other products with renovation, repair and other functions. It is just a long-term care product, which has four functions: hardening, polishing, anti-skid, and stain removal.
From a scientific point of view, the process of crystal surface care is actually a chemical action, which is formed by the chemical action of crystal surface agent (acid) and stone substance (calcium carbonate). When chemical action occurs, the lime surface hardens after being heated and pressurized by the ground wiper, and the heat is transmitted through steel wool to form a smooth and hard calcareous glass surface. Another function of steel wool is to remove some stains corroded on the ground and absorb them into the steel wool, which has a cleaning effect. The area of crystal face agent sprayed each time shall be subject to 2m2m, and it shall be polished meter by meter gradually until it is enough. Every time the crystal face agent is dried by the floor wiping machine, the stone shall be stopped immediately when it emits glass light, otherwise the brightness will be damaged by excessive friction, which will turn into a reverse effect, especially for white stone. |
