Concrete expansion Jingzhou, Jingzhou silent broken agent manufacturer, price efficient carbatex silent broken agent in coal mine production application Jiaze efficient silent broken agent (also called rock expanders, carbatex broken stone agent, split stone agent, carbatex static broken agent) is China Building Materials Academy invention developed Jiaze products. It is a high-performance security powdery crushed material, with water carbatex HSCA demolition agent into a slurry poured into the rock or concrete borehole by condensation, hardening occurs remarkably solid expansion can produce greater than 50 MPa expansion pressure, the expansion of the hole wall generated greatly exceeds the tensile strength of concrete and rock crushing leaving. After 8 to 24 hours at no vibration, no dry sound, no flying rocks, the absence of harmful gases, the safety crushing or cutting jobs. First, carbatex silent broken agent suitable range: 1, are not allowed and should not be used under conditions of mechanical disruption zhayao crushing and construction, concrete works need to be removed, loose rock engineering. Is not allowed and inappropriate appeared flying stone double-track railway, high voltage transmission lines, communication cable; if banned from ignition, flames and high temperature storage tanks, gas tank, oil and gas pipelines, zhayao library construction crushing demolition of dangerous goods warehouse next next to the construction, broken construction offices and schools, public places and homes beside dense; not allowed to appear strong vibration and suitable for crushing construction, such as building demolition reservations, dangerous slope treatment, rescue cultural relics protection project, are not allowed and inappropriate emerge Broken Construction great sound and noise; such as broken city construction late at night and so on. Construction of the project 2 broken, urban construction, large equipment concrete foundation removal, water, roads, bridges, tunnels and other projects need "Static Breaking Method." Reserved rock and concrete part of the integrity and structural strength requirements can not be compromised in any way broken removed. 3, ordinary rock crushing and loosening, large shaft, pile, pile excavation trench dug caisson.

According to China's current static crush mature experience, drilling aperture elected 42mm. The mine rock mostly fine sandstone rock hardness is generally at F: 10 or so, according to the cross grid-like arrangement of drilling, drill hole spacing and row spacing is determined as 250 ~ 300mm. The more free surface, the greater the amount of rock crushing unit, the better the economic benefits, therefore, formed for the next broken more free surface, arranged drilling should improve the crushing effect in consideration. V. Notes 1, the construction environment must choose the right carbatex SCA demolition agent model, not free interoperability. 2, the agent after mixing the slurry must be within 10 minutes filling in the hole, over 10 minutes, its liquidity and the crushing effect is significantly reduced. 3, the construction, for safety reasons, it is best to wear protective glasses, before cracks after grouting to not be on the opening look, just in case the discharge phenomenon occurs when damage to the eye. 4, the agent slightly corrosive slurry, hit the skin or into the eyes to rinse with water immediately. 5, the agent should be stored in a dry place to prevent damp, without moisture, the shelf life of one year. 6, hot summer should choose a slightly lower temperature in the evening into the operating construction.
