Stone common sense knowledge of patterns: The direction of patterns in the processing of mosaics depends on the specific situation, and there are no standards to refer to. As for circular patchwork, the pattern can be around the circumference or along the radius. Whether it is around the circumference or along the radius, the consistency of the pattern must be ensured. In terms of square flower patterns, the patterns can radiate along the length direction, as well as along the width direction, or simultaneously radiate towards the four sides along the main width direction. As for how to do it, it depends on the decorative effect achieved by the processed mosaic. Color lines, color spots, cracks, holes, sand holes, mold spots: In terms of the quality of the mosaic, these stone defects are not allowed.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

There are three main types of superhard material coatings, namely diamond-like carbon, diamond, and CBN. These coating materials are all pure diamond or pure CBN, so their hardness is the same as the deposited material. Compared with PCD and PCBN, they do not contain binders, so their hardness, wear resistance, and other properties are greatly improved. The performance of diamond coating and CBN coating is the same as that of the raw material, except for the thin film, which is similar to ceramic coating when used. Here, we will focus on introducing diamond-like carbon films. Diamond Like Carbon (DLC) films have similar advantages to diamond films, with good anti friction and wear properties. The preparation process of DLC films is becoming increasingly mature, and large areas with low surface roughness can be obtained at very low deposition temperatures. Diamond films require higher deposition temperatures (about 8 ℃~1 ℃), which limits many substrate materials, such as high-speed steel, and it is also difficult to deposit uniformly on a large area, resulting in a rough surface.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

Adjustment and fixation: After the panel is temporarily fixed, adjust the levelness. If the upper opening of the panel is uneven, a corresponding double stranded copper wire pad can be placed on the connecting flat steel plate at the lower opening of one end of the bottom of the panel. Adjust the verticality and adjust the gap between the stainless steel connector at the top of the panel and the wall until the panel is vertical. Top panel installation: The last layer of the top panel should be installed and adjusted according to the general requirements for stone slab installation. A 2mm thick wooden strip should be hung in the gap between the structure and the stone slab, with the top of the strip being 25mm below the upper opening of the stone slab. The hanging point can be set on the connecting iron piece. Colorful aluminum wire hanging wooden strips, after the wooden strips are hung, fill the gap between the stone slab and the wall with filling material, and fill it tightly to prevent grout leakage during grouting.

Several aspects to pay attention to when using stone protection products: Waxing has been widely used as a method of protecting stone. It is often used on paved stone floors. But its protective effect on stone is limited, with poor weather resistance, unsatisfactory anti fouling effect, and easy adhesion of dust. Nowadays, people have found that waxing can also cause some harm to stone, because it is used as an airtight sealing and protective material applied to the surface of the stone. After the pores of the stone are sealed, the moisture inside and behind cannot be released, and it accumulates inside the stone for a long time, causing the stone to change. There is also a type of liquid wax commonly applied to interior walls, which is a film material with the main drawback of affecting the natural texture of the stone.
