Zhengzhou silent expanders where to buy? Zhengzhou rock crushing agents manufacturers wholesale carbatex silent expansive precious jade stone blocks limited silent cutting, granite and marble and other precious stone resources, to implement protective mining. It was first punctured the artificial splitting of the original method used. With zhayao after savage methods baopo, which is undoubtedly the "golden eggs" on the devastating stone resources. Now the government has banned this mining method. Early 20th century, Italy, Germany and other developed mining method Wire Saw achieve a planned protective mining precious stone blocks. But investment, complicated equipment, strict operation, suitable for large-scale mining. But for small and medium sized mines or remote mountain areas does not apply. Since Japan and China has successfully developed carbatex static crushing agents on stone mining, drilling using drilling machines, irrigation 入嘉泽 silent broken agent (referred carbatex SCA broken agent) paste by 8 ~ 24h, you can put Rock cut off, almost no damage, the amount of small plastic blocks, the finished product rate is greatly improved. This method is suitable for the overall good of the ore body, low investment, simple equipment and workers to operate easy to master, mining costs are lower. Today, part of the stone mining of stone blocks have adopted this silent cutting technology. Italy, Australia, South America and other stone stone mine also introduce this open technology. Although the mechanism of stone blocks and concrete cutting, rock crushing mechanism is basically the same. However, its particularity, namely in the borehole irrigation Ru Jiaze SCA broken agent, to break into chunks of rock, rather than broken into fragmented. Jiaze agents SCA were broken cutting Dushan jade, marble and granite field tests proposed cut stone blocks of the mechanism carbatex SCA broken agent. Select three different hardness test rock - Jade (including jade rock gabbro), marble and granite, they are crystalline particles of mineral aggregates, it is hard and medium-hard rock, marble and granite has a clear all anisotropic characteristics. Experimental determination of mechanical properties of the three following parameters of rock mechanical properties of the rock three rock Title density (t / m 3) Compressive Strength (MPa) Tensile strength (MPa) brittleness (R Pressure / R Pull, MPa) jade alone 167.4 18.0 9.3 3.09 marble (Township) 2.71 2.66 34.7 160.2 7.7 20.8 1.5 23.1 Note Granite (town square): Marble, granite mechanical properties parameters are Geology and Mineral Resources Bureau of central laboratory assay values. By experiment, we believe that the rock cut resistance is mainly determined by their size and fragility of the tensile strength values. Greater tensile strength of rock, the more difficult to cut; the higher the value, brittleness, cutting more favorable. The so-called brittleness values ??refer to the same rock, the ratio of compressive strength and tensile strength in the same direction. From the table, three rocks, jade alone hardest cutting, marble cutting most vulnerable. Through trials have confirmed this law. Jiaze silent broken agent cutting mechanism on the rocks, we passed on the jade, marble and granite mining and monomer hundred cuts cutting test to get information to prove it with all the different zhayaobaopo rock. zhayaobaozha damaging effects caused by rock interaction is the result of stress generated instantly spread zhayao accompanied by a high temperature high pressure gas generated expansion. The rock cut Jiaze silent broken agent is a hydration reaction carbatex silent broken agent in the borehole slowly to generate Ca (OH) 2 crystal formation expanded its expansion pressure of the surrounding medium play a destructive role. It features a static pressure of the rock fracture. Carbatex silent expanders, crushing body does not produce vibrations, noise, flying rocks, dust and toxic gas, is a pollution-free environment-friendly products, not a flammable and explosive materials. Transport, storage safe, reliable, easy to use. This product is stable crushing effect, it will generally be crushed crushed within 12 hours of the onset. 1, the expansion force. It can be up to 120 MPa (1200kg / cm2). 2, the reaction time is short. The maximum expansion force can occur within 15 minutes. The reaction time may also be between 15-12 minutes adjusted. 3, to be broken is broken, it needs to stay then stay. It can be easily controlled to be broken after the broken body shape. 4, the construction is simple and easy to operate. After stirring the product with clean water can be poured into the borehole poke tight, operator training time is very short to operate. 5, without the use of noise, no vibration, no flying rocks (do not rule out the occurrence of punching), no gas, no shock, no toxic and harmful residues, is a pollution-free environment-friendly products. 6, long shelf life. No damage in the packaging, storage, drying, under substantially constant temperature (16 ℃ -32 ℃) conditions, one year shelf life, even up to 18 months.
