How to judge the strengths and weaknesses of diamonds, every practitioner should know professional knowledge. The following briefly discusses several important indicators for judging the strengths and weaknesses of diamonds.

Abrasive strength includes tensile strength, flexural strength, compressive strength and impact strength.

The grinding process is the process of cutting the metal on the surface of the workpiece by the abrasive particles on the surface of the abrasive tool. The quality of the grinding process depends to a large extent on the cutting performance of the abrasive tool. There are many types of abrasive tools, not only the shapes and sizes of the abrasive tools are different, but also the abrasives, particle sizes, binders, hardness and structures that constitute the abrasive tools are different. Therefore, different grinding tools have different characteristics, and the grinding tools with different characteristics are suitable for different processing ranges. In order to obtain the expected grinding effect, different grinding tools must be selected for different grinding occasions.

Cracks, potholes and other phenomenona may appear on the concrete floor when the service life has expired or under high-intensity work. So, whether it's sanding or resurfacing, here are some suggestions for you.

Diamond soft grinding discs have many advantages and it is precisely because of the many advantages of diamond soft grinding discs that they are widely used.

Grind well, the stone itself has a clear color, radiant, beautiful and durable, better than grinding to 1000# for powder. If the grinding is not good, all defects such as insufficient optimization, scratches, whitening etc, will be magnified after polishing, which is visually unbearable.

The grinding and polishing of the flat slabs must be done in a certain order and according to certain principles to ensure the quality of the grinding and polishing of the surface, otherwise it will only be useless.

The main items of diamond grinding tools quality inspection include appearance, geometric dimension, balance and grinding performance inspection.

Grinding is basically unidirectional cutting, and it is more difficult to achieve a mirror surface. The more commonly used method is to use free abrasives for multi-directional grinding to achieve mirror surface results. However, the free abrasive polishing method is prone to problems such as too long processing time and difficulty in maintaining dimensional accuracy, because the removal force of free abrasives is weak, and most of them use soft materials as auxiliary equipment, such as polishing pads or wool wheels.

High-performance concrete technology is quite different from traditional concrete. It has excellent characteristics such as high durability, high workability, high strength and high volume stability . It is currently considered to be the most comprehensive concrete in the world. It has been valued by many important projects and has been widely used. High-performance concrete technology shows unique advantages, especially in bridges, high-rise buildings, new buildings and other projects, which is conducive to accurately grasping the safe service period of the project, improving its economic rationality and adaptability to environmental conditions in the project, etc. , thereby bringing obvious benefits to the project, which is also considered as the development direction of concrete technology.

Polished concrete floors are fast becoming one of people's favorite floors. Polished concrete floor refers to the concrete surface formed after the concrete is gradually polished by grinding tools and combined with chemical hardeners. Constructors use chemical hardeners to penetrate the naturally poured concrete to strengthen its surface strength and density, and improve its flatness and reflectivity through mechanical grinding and polishing, so that the concrete floor has both performance and special decorative effects.This is why most retail, warehouses and offices choose polished concrete floors.

The selection and use of grinding discs can be followed regularly: diamond grinding discs or concrete thick grinding discs are used for ground leveling and rough grinding; the rotating speed can improve the efficiency; try not to skip the number of grinding discs; dry grinding saves consumables than water grinding, but the water grinding treatment will make the ground more uniform and delicate; after washing the ground and drying it, use a thin grinding disc for high-speed dry polishing for better results ; the use of sponge polishing pads can improve the brightness of the ground.
