Definition of Stone Electrolytic Plate: Electrolytic stone refers to placing the stone to be changed in color into an electric furnace, heating it to a certain temperature, and holding it for a certain period of time before it changes color. This is called electrolytic stone. Some stones require protection to achieve the desired effect. The main raw material used for electrolytic stone is granite. For example, electrolytic sheets such as gold hemp, gold diamond hemp, and carrageenan. The advantages of electrolytic stone board over stone dyeing board are that stone dyeing board refers to stone slabs that are colored (or enhanced) by adding dyes to natural stone. It is divided into two types: fully dyed and surface dyed. The common type of fully dyed stone on the market is water immersed red, while natural stone slabs are soaked in inorganic iron salts and then decomposed into iron red at high temperatures to produce red stone. There are many surface dyed stone slabs, which are directly brushed with organic dyes on the surface of the stone slab to enhance or enhance the color, with a short time effect.

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.

Dyeing method: Arrange the stones to be dyed one by one on the floor, clean the surface dirt, stains, impurities, etc., and then use a hair dryer to dry the moisture of the stones. The method is to expose the stones to the sun, which will make the dye easily absorbed into the stones. Put on gloves and apply dye (liquid) onto the surface of the stone using a cotton cloth. Observe the effect. If the color is not in place, apply 2, 3, or more times until satisfactory. Generally speaking, applying 1-2 times can meet the quality requirements. After the color meets the requirements, use steel wool to remove the stains on the surface of the stone, and then rinse it clean with water.

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.

Under general technical requirements, when the production stripping ratio is around. 3, the economic waste rate of granite ore is 15% to 25%. When using a mobile crane for the height of the mining site steps, the step height is 4-6m; when using a small mast crane, the step height is less than or equal to 14m; when using a large mast crane, the step height is less than or equal to 62m. The slope angle of the steps is generally 9 °, which is determined based on the stability of the rock. The width of the stone strip is determined by the performance of the mining equipment, the specifications of the waste material, and the condition of the cracks, generally ranging from 1 to 3 meters. The length of the working face is generally 5 to 15 meters for manual mining, and 15 to 2 meters for flame cutting machine mining.

This type of stone has a pure white color, with white and pale yellow being the most common. Their texture is often rough, and sand holes can be observed with the naked eye. The Afghan white jade, due to its delicate and even texture, has a glossy and oily appearance, and the jade flowers cannot be seen with the naked eye. Often used to impersonate high-quality white jade or sheep fat jade. The method of identification is very simple. Just use your fingernails to scrape hard. If you can scrape off a little white stone powder, it's not white jade. The hardness of carbon rock jade is 3 degrees on the Mohs scale, with a density of 2.7 grams per cubic centimeter, a refractive index of 1.4866, and a glassy luster, appearing transparent to opaque. The hardness of carbon rock jade is much lower than that of Xinjiang white jade, and it can be easily carved with a small steel knife; Its density is also lower than that of Xinjiang white jade, so it feels lighter when weighed in the hand, making it easier to distinguish.
