Taizhou silent expansive demolition agent, Taizhou splitting agents, ore crushing agent Operation 1, carbatex silent broken agent before construction preparation: now, according to local temperatures, pharmaceutical temperature, mixed with water temperature, body temperature to be broken, if consistent with the requirements; Check pharmaceutical packaging is damaged. Make sure to have the following before operating materials and items: (1) drug, (2) clean water, (3) buckets, mixing bowl, (4) poke a stick, (5) protective glasses (6) rubber gloves, (7 ) alternate clean water and towels. 2. Broken scheme design: Cloth front first to determine that at least one more free surface (free surface), drilling should be directed parallel to the free surface as possible; cutting rock or concrete in the same row drilling should be kept as far as possible on a plane. The more free surface, the greater the amount of broken stone units, economic efficiency is also higher. After crushing plan was finalized, the first to use the drilling rig. About diameter, pitch, hole depth and broken design, it should be crushed according to the specific circumstances. Such as: concrete structure: whether steel, rebar diameter, arranged situation; rock structure: behavior, joints, to be crushed in size. Pitch and row spacing (resistance line distance) Setting: size and hardness of the rock and row spacing pitch, concrete strength and reinforcement distribution is directly related to, the greater the hardness, the higher the concrete strength, reinforcement dense fabric reinforced when coarse pitch and row spacing smaller, otherwise large, pitch and row spacing layout. 3, drilling (1) Drilling diameter and the crushing effect is directly related to drilling too small, is not conducive to drug fully effective; drilling too easy punching. As noted in strength to be crushed, the hardness, the array density steel is recommended to use a diameter of 38-45mm drill. (2) drilling over water and residual ash high pressure wind washed off opening should be clean soilless Gravel. (3) Drilling depth is generally better in the 1-4 m. 4, agents according to the season and the temperature stirring choose to adapt carbatex HSCA demolition agent model agent, the amount of the actual number of expanders, the powdered medicament are mixed together with water into the pot quickly stir into a thick paste having fluidity is reached . For vertical holes drilled from the top down, the weight ratio of water and chemical is usually 0.34 to 1. For example, 5kg agents against 1.6kg of water. For horizontal hole, the slant-hole and vertical hole drilled from the bottom up, the weight ratio of water and chemical is usually 0.28 to 1. Under normal circumstances, the water temperature should be consistent with the climate temperature. The reaction is not ideal, usually associated with the climate temperature. If the weather temperature is below 0 ℃, it is recommended prior to mixing of water heated to 20 ℃ -30 ℃. Available sticks or hand-held mixer mixing stirring, stir together until uniform, making it liquid paste or clay-like, quickly poured into the hole can be. Mixing should have been with the medicine slowly into the water against the good, rather than water slowly pour medicament. Stirring constantly should be poured in. Pour and stirring faster, added to the water poured into the borehole from the agent to the end of time should be controlled within 5-10 minutes, or easy punching. 5, perfusion before charge should ensure that the drilling hole and the hole next to clean, the remaining water and residues with high pressure blown clean. Every time filling agent must observe to determine rock, agents and mixing the water temperature is not satisfactory. For vertical holes, the mixture was poured into the wells directly, compacting the mixed body filler, filled up. For horizontal holes, inclined hole, up the hole, poured into the hole in the mixture ratio of water and agents should be 0.28 to 1, was a clay-like. Use a pore size consistent with the pipe, the pipe diameter by half. The clay-like mixture was poured into a steel pipe in half, then the other half with it closed. The pipe is inserted in the hole closed, until the reaction is complete. Plugged up the angle should be broken in the same direction with mining objects. Steel can be used repeatedly. After stirring the agent can also be pressed into use mortar pump, opening with Wong sealed to ensure water does not flow agent. For large equipment base quarry and crushing volume of construction, coordination with the operator it is very important. Pay would be by way of filling group. Each team of primary and secondary two hand filling composition. When medicine stirring, the main responsible for dispensary hand filling weight and stirring, deputy responsible for Pharmacy hand filling water in the mixing process. When filling the main hand is responsible for filling the filling into the hole, vice filling hand responsibility to ensure chemical tamping, after opening with complete coverage of old sacks. Each group a "synchronous operation, less mixing ground equipment" manner. Namely: Each construction workers during each cycle of operation holes mounting holes are not responsible for much. Mix each dose can not exceed the actual amount of work done. Filling each team dispensary, add water, mixing, filling process should basically keep pace, allowing maximum expansion efforts in each well agents remained the same period appear conducive to concrete and rock crushing. The filling process, has begun a chemical reaction agent (performance began to take gas and temperature hot) is not allowed into the hole. Water was added to the end of the filling agent, the time of this process can not be more than five minutes, or easy punching. Rock just after cracking, the crack can be added to water, to support continued drug reaction, get better.
