How to improve the mining and sawing rate of stone mines has always been a worldwide problem. Recently, the domestic independent research and development of stone block material infusion reinforcement adhesive and infusion reinforcement technology has achieved comprehensive success. The project has obtained 3 national patents and passed the domestic expert appraisal, its infusion adhesive performance, stone block material infusion equipment and The reinforcement process fills the international gap and ranks internationally leading. It has completely changed the problem of low stone material mining and sawing rate in the past. In one fell swoop, the stone material production rate has been increased from 20-70% to over 98%, and the annual output value of the stone industry is nearly 10 billion yuan. A revolutionary technological innovation in the stone industry. The natural veneer stone is mined from the mine and cut into a wool board in a stone processing factory, which is then ground, polished and cut. About 30% of the total amount of stone blocks is loose and porous, and the cracks are wide and deep. The process of sawing into a wool board is easily broken into waste rock, causing huge waste of natural resources and major economic losses of stone enterprises. Has always been a top priority for the stone industry.
How to solve this problem, the country has summarized more than 10 years of industry experience and domestic and foreign well-known chemical, mechanical, stone expert resources, invested nearly 10 million funds, developed a stone block material infusion reinforcement adhesive and infusion reinforcement technology. The material pouring glue has extremely small viscosity, strong permeability, colorless and transparent, can be reinforced under low temperature and humidity (high humidity) conditions, and can also be tuned into various colors according to the color of the stone, which can fully satisfy the stone blocks. Mining and sawing site construction requirements. The supporting high-pressure infusion equipment and reinforcement technology can quickly infiltrate and reinforce the permeability cracks with a width of more than 0.1mm. The stone cutting material after infusion is nearly 100% cut and can not be sawed. Almost all of the blocks can be brought back to life. At present, the technology has been used in many stone production enterprises and mines in China, and has been applied in more than 100 enterprises in more than 10 countries including Turkey, Egypt, India and Brazil. The infusion reinforcement effect is excellent, the production efficiency is high, and the perfusion cost is low. (In the case of 5 cubic meters / piece of blocks, the cost of infusion reinforcement is less than 800 yuan), and the supply of products and equipment is in short supply.
