If the stone-paved in hotels and office buildings is stronger than the wear strength, it can’t compare with the elevator hall and car. These two places are the only way for people to come and go in the whole region, and the crowd will concentrate here for diversion. With such a high flow of people trampling every day, the wear intensity can be imagined. If the stones in other areas have high wear strength in some places, they can at least make do with it;
But the maintenance of the elevator hall and car sometimes makes people give up directly. The so-called “endurance maintenance” — because it’s so worn that even polishing every day can’t be trampled by such high traffic — it’s uncertain, so we have to let it go.
However, there are ways to keep the elevator hall and car stone in a “basic beautiful state”. In this article, let’s talk about this problem.
● Difficulties in difficulties
In each area of a building, the degree of ground wear is different, which is mainly determined by different useful functions. For example, the stone-paved in hotels, office buildings and shopping malls, where people don’t go often, the wear degree is very low; however, the corridor, aisle, toilet door and other areas bearing a large number of people trample on, the wear and tear are very serious. These areas are the difficulties of stone maintenance. Among them, the stone maintenance of the elevator hall and car is undoubtedly the “difficulty among the difficulties”.
1. Too many people
The area in front of the elevator door is collectively referred to as the elevator hall, with an area of less than 10 ~ 15 square meters, more than 30 ~ 50 square meters, and some are part of the hall. No matter how large the area is, it is a diversion point for taking elevators. According to the building scale, the number of elevators is less than 1 ~ 2 and more than 10. No matter how many people there are in the whole building, they almost have to pass through this area. The flow of people is too large. Not to mention that the stone can’t be damaged, even the steel plate can be trampled.
2. Wear characteristics
The wear of elevator hall not only lies in the large flow of people but also in the characteristics of wear. For example, at the entrance and exit of the hall, the flow of people is also large, but the wear of the elevator hall is not as prominent as that of the elevator hall. Why?
This is related to people’s movement habits in front of the elevator hall: when people are waiting for the elevator, they will not stay still, but move and turn around to relieve their emotions; These actions will run through the whole waiting time for the elevator, with an average of almost 3 ~ 5 minutes. These actions will increase the wear of the sole to the stone. In contrast, at the entrance and exit of the hall, people almost move forward in a straight line, and there are few actions such as staying in place and turning around. The elevator car is the same: personnel access, moving position, turning around, pressing buttons, and other actions will aggravate the wear.
● Maintenance suggestions
1. Material selection should be hard
Since the elevator hall and car have to deal with such a large flow of people, it is necessary to select marble or granite with high hardness for this area. Do not choose soft limestone, cave stone, etc.
2. What material is suitable?
As mentioned earlier, the flow of people in these areas is so large that even the steel plate can be trampled. What material can withstand it?
① Is crystalline material OK? Can’t carry it.
Because the bright layer formed by crystallization technology on the stone surface is generally composed of calcium crystal layer, wax, and resin, which are not wear-resistant. The “endurance maintenance” mentioned earlier means that if the maintenance is carried out with crystallization technology, it is OK in other areas. However, in the high wear area of the elevator hall and car, it is basically “polishing at night and stepping on it during the day”. It is difficult to affect, so we just give up.
② Is glaze sealing technology OK? I can’t stand it.
The glaze sealing material is composed of silicon dioxide (SiO2). The bright layer formed by this technology has a very high density and hardness, and the wear resistance is much higher than that of the crystalline surface. However, in this area where even steel plates can be trampled, the silica layer cannot be damaged.
③ How to maintain it?
At present, only the double insurance of “physical polishing + sealing glaze” can maintain a “basic beautiful” state in this high wear area.
3、 Physical polishing + glazing
In this high wear area, if you want to maintain a beautiful decorative effect, you can only solve it by improving the hardness of the bright surface. For example, sealing glaze is a method to improve the hardness of a bright surface, but it is not enough in practical application. Because the wear and tear of the elevator hall and car are too serious.
1. Operation method
Step 1: grind the stone to M7 (equivalent to the standard 3000#) with grinder + VD easy grinding plate, and directly grind the stone gloss to more than 85 degrees.
Step 2: use the crystal surface machine + VD refined steel glaze, and polish it until it comes out. To deal with the trampling of elevator hall and car superelevation pedestrian flow, this area needs to be glazed 4 ~ 5 times.
Note: by adopting the method of “physical polishing + sealing glaze”, the basic gloss of the stone has been very high. In addition, with the sealing glaze layer 4 ~ 5 times, the sealing glaze layer bears the wear and tear of trampling by people in daily use and does not damage the basic gloss of the stone. It is enough to maintain the stone of the elevator hall and car in a “basic beautiful” state.
2. Maintenance frequency
This frequency cannot be calculated according to a fixed time but should be judged according to the degree of decline in on-site gloss. For example, after grinding and glazing, the test gloss can reach about 100 degrees; The next service should be done when the gloss drops to around 80 degrees. The purpose of this is to always wear the sealing glaze layer and not damage the gloss of the foundation. Once the basic gloss is not stepped on, the maintenance will not be effective – with this technology, the beautiful effect can be maintained in the elevator hall and car for 15 ~ 60 days depending on the flow of people.
An elevator is a place we touch every day. The quality of the stone in the elevator door pocket and Bridge car directly affects our mood of life and work. Therefore, we should cherish the stone in this area. Well, that’s all for today’s article. I look forward to your email sales@sntstone.com Criticism and correction.
