Concrete, which we have seen in our daily life, is an important and indispensable material for construction. It is made up of cementitious materials (binders), coarse and fine aggregates (sand, stone), water and other admixtures in proportion. Artificial stone hardened under appropriate conditions. With the advancement of technology, concrete manifestations are becoming more and more diverse, such as fair-faced concrete, decorative concrete, waterproof concrete, polished concrete floor and so on. Definition of polished concrete: The concrete floor is polished by a grinding machine and using a hardener under the combined action of chemical and physical. A concrete floor with a certain gloss and high hardness. Advantages of polished concrete: 1. Beautiful. Through polishing, various pre-added aggregates in the concrete are presented, with a certain decorativeness. 2. Environmental protection, sustainable. Raw materials are environmentally friendly and pollution-free, and can directly pol...

The polishing head  of  polishing material is often used in electric grinders, crane grinders, electric drills, etc. It is a small-scale grinding tool with a handle for polishing materials. Polishing material grinding head is mainly divided into: ceramic polishing grinding head, rubber polishing grinding head, diamond polishing grinding head, emery cloth polishing grinding head and so on. 1.  Ceramic polishing head: Granular sand (usually brown corundum, white corundum, chromium corundum, silicon carbide) is sintered by polishing material ceramic bond, and the center is supplemented by a metal handle. It mainly grinds various metals for the grinding of the inner wall of the aperture and the correction of the mold.   C eramic bond transitional polishing pad s  for c eramic polishing head  can effectively remove scratches on the surface. 2.  Rubber polishing grinding head: The finer-grained sand is combined and synthesized by a rubber bond for polishing ...

After receiving the abrasive tool, carefully check whether there are cracks and other damages, and carefully check whether the relevant trademark signs on the surface of the diamond tools are correct, clear and complete. Grinding tools should be handled with care to prevent vibration and collision, and rolling on the ground is prohibited.  Abrasive tools should be protected from moisture and freezing when stored, and the room temperature should not be lower than 5℃.  Resin diamond tools should not be in contact with alkali substances, and rubber abrasive tools should not be in contact with oil, so as not to reduce the hardness and strength. When the grinding wheels are stacked, the stacking height generally does not exceed 1.5m. Avoid deformation when storing flake grinding wheels. Those who have been stored for more than one year can only be used after passing the revolving strength inspection.

Concrete floor  is a kind of integral ground that uses cement and stone particles as the main material. In the course of China 's ground development, it has successively experienced such forms as   terrazzo floor , fair-faced concrete floor ,   and colored wear-resistant floor . Still fashionable terrazzo floor Terrazzo has the strength, wear resistance and durability of natural stone, and it is smooth, easy to clean, and good integrity. As the indoor floor of a large number of public buildings, it is practical and beautiful. The new type of terrazzo has new developments in color and pattern. The decorative effect can meet the modern aesthetic needs, and it can also meet the requirements of environmental protection. It is safe and non-toxic, does not release harmful substances such as benzene, formaldehyde, and has no radioactivity. In addition, compared with building materials with similar effects, decoration investment can be saved by 2/3. Many universities and hospital...

Diamond tooling cuts or polishes a concrete surface using one of the hardest materials on Earth, that is diamond grains, a distinct advantage compared to tools that use common abrasives such as corundum and silicon carbide. To achieve the greatest productivity on hard concrete, a soft-bonded diamond needs to be used; conversely, a hard-bonded diamond needs to be used on soft concrete. Bond In order for a grinder to use diamonds to cut, small chips of diamonds are suspended in a bond made from metal, resin, carbides, hybrid or mixed-resin (a blend of both resin and metal bonds) or polycrystalline PCD. Metal bonded diamond tools  are ideal for removing brittle adhesives Hybrid transitional diamond tools  are ideal for removing tacky adhesives, leaving a smooth finish and no damage to concrete PCD removal tools  are ideal for removing epoxy coatings, adhesives, leveling compounds or membranes and quite popular because they are so aggressive   Segment Segment refers...

High bonding strength The resin bond has higher bonding strength than the ceramic bond, and the mechanical strength of the made abrasive tool is higher than that of the ceramic abrasive tool. It can be used at higher speeds, can withstand greater grinding pressure, and is relatively safe to operate. Therefore, it is widely used in rough grinding processes in steel, automotive bearings, chemical machinery, construction and other industries. Have a certain degree of flexibility Resin is a polymer compound, and it has certain toughness and elastic deformation to buffer the grinding pressure, so the grinding effect is good. And it can improve the surface processing quality of the workpiece due to its good polishing effect. Wide range of applications With the emergence of new resins, resin abrasive tools with various strengths and properties can be made, which can be used as abrasive tools for barren grinding, rough grinding, cutting, semi-finishing, fine grinding and polishing. Abrasive t...

In the autumn of 1958, experts from the Cultural Relics Department of Gansu Province carried out a cultural relic survey in Tianshui City of Qin'an. In the suburbs northeast of the county seat, archaeologists heard from local residents that they would often dig out broken pottery pieces or even complete pots here. Therefore, the experts carefully surveyed and excavated the area, they found several tombs and house ruins, and also unearthed some jade pieces, clay pots and a large number of animal remains. After scientific appraisal, experts determined that this is a Neolithic site of human life which was about 4900-8120 years ago, and named it "Dadiwan Site". Afterwards, in order to better protect and study information of the site, experts carried out in-depth excavations about seven years. At the same time they unearthed "six firsts", which were the early Chinese crop; the first Chinese Purple-red painted pottery; the original prototype of Chinese characters whic...
