Where there is a silent expansive Yulin, Yulin mine blasting demolition agent factory production limited jade, 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. 1, different types of demolition agent hydration reaction to about 24h, the expansion pressure close to the maximum, but can continue to grow by 2, the expansion pressure increasing fragmentation agent with the water-cement ratio and a decrease of 3, the expansion pressure broken agent with increasing temperature 4 increases, the expansion pressure is increased fragmentation agent parameters are broken object aperture increases with the aperture / mm Pitch / mm hole depth resist line / mm amount / (kg / m3) of soft rock crushing 35 ~ 50400 ~ 600 H 400 ~ 600 8 ~ 10 in the hard rock crusher 35 ~ 65 300 ~ 600 1.05H 300 ~ 500 10 ~ 15 rock cut 30 ~ 40 200 ~ 400 H 1000 ~ 2000 5 ~ 15 35 ~ plain concrete breaker 50400 ~ 600 0.8H 300 ~ 400 8 ~ 10 reinforced concrete crushing 35 ~ 50 150 ~ 300 H 200 ~ 300 15 ~ 25 cloth eye design principles: center hole spacing depending on the pore size and hardness of the rock, if you want the best crushing effect, in normal must be pre-tested before construction. Small aperture, the center distance will be smaller; a large aperture, the center distance will be greater, will accelerate the break time, for example: dia30 min: 35 cm (hole t0 hole), dia 35min: 40 cm, dia 40mm: 45 cm, dia 45 mm: 60 cm. Hole diameter and the crushing effect is directly related to the eyelet is too small, it is not conducive to drug fully effective; eyelets is too large, easy punching. It is recommended drill bit with a diameter of 40mm. When the body is crushed object is isolated, drilling depth of 80% to 90% broken body thickness. Hole more than water and residues with high pressure blown clean. Broken agent is a powder material with clean cold water before use thoroughly mixed. That is according to a pack of drug plus 30% to 34% water (by weight) to deploy Whey, which is about to pour stirred 1.5 L ~ 1.7 L water container, then slowly pour a bag of 5 kg fully broken agent stirred into the slurry flow, such as hand-to wear rubber gloves when mixing. The good mixing broken agent slurry quickly pour hole after drilling with slightly less than tamping rods poke poke tight, after filled immediately with a sponge or cloth head orifice plugged. During operation, all agents must be filled to 100% of the deep hole. Workers in the construction, must ensure teamwork, to do with the Chiang Khong, with the mix drugs, with drenching already steaming hot or agents shall not begin to hole filling, mix less frequently installed in order to ensure the most good construction effect, filling the hole after work is completed, arrange someone to care, unrelated persons should not be near, prevention spray Fasheng when making chengren staff casualties. Drilling → stirring → grout → cracking (product easy to operate, approachable, you teach to use) carbatex silent expansive professional rock mining, concrete crushing agent products manufacturer, the factory has 10 years of production experience , we are very confident in their products, and for you to be able to solve problems in construction above and am very pleased. The company's products are widely used in various engineering fields nationwide, mine construction, civil air defense projects, pit construction all suitable. Jiaze silent expansive: Note on face and water-cement ratio problem cases, models may not be interoperable, rain inconvenient construction. Specifically we recommend that you consult a sales manager carbatex exchange specific operations. Our minimum order quantity, according to customer demand, there is a minimum order quantity proposal, which is the result of our factory based on years of experience obtained.
