While actually maintaining the bend stone, the environment surrounding the stone, and prevent water erosion and chemical detergents. Therefore, the stone can be polished after a very short period of time after liquid contaminants are removed from the surface. If the surface has been eroded and lost its luster, the more serious it should be replaced by a stone care company. Surface scratches, timely repair, or water easily enters the inside of the stone through cracks, pathological changes in the bend stone, how to repair it? Clean up contaminants, then polish with a polishing machine, and use curing agents for maintenance. How should the yellow stone attack be modified? First of all, let's use a neutral detergent, which is difficult to organize. In addition to the modification agent, we should use a modification agent, and then clean it with clean water, and clean up the appearance of moisture with a dry rag in time. In practice, bend stones are modified, and appropriate methods are selected to treat them according to the practice of lesions, but we can put them into use according to the common sense of “preventing” the maintenance of curved stones. In recent years, with the large-scale development of corner stone mining resources and stone mining machines, I saw that the cost of curved stone is getting less and less, and the output is getting bigger and bigger, so the price of corner stone has a strong competitive advantage in the market. Curved stone is a granite material with producibility, weather resistance, acid and alkali resistance. Curved stones set the edge of the road with other layout and boundary stones, between the separation zone and the pavement, between the pavement and the pavement as usual, are appropriate ground laying, municipal greening, highway and other large-scale engineering stones. The main point of bending stone processing is that first from the bend stone mine waste will be cut into pieces of waste, and then cut into pieces of jade to recruit big to see the stone being polished, corner, axe, fire and other processing into ready-made curved stone.
