Where to buy good quality Ankang silent expansive? Preferred Jiaze HSCA-III Uses and Features: 1. Basis of the main purposes: 1) stone cutting and crushing: such as granite marble, jade, iron ore and other mining excavation of tunnels and underground channels and other underground construction and other engineering rock crushing. 2) (reinforced) concrete building demolition and fragmentation: as wall and column piers dam removal and other large equipment. 2. The main outstanding features: 1) Security: Soundless Cracking Agent object Splitting process without vibration noise no flying stone dust no harmful gases. Especially non-ideal environment blasting broken tools. 2) Controllable: It can be designed according to different needs of different drilling customers in order to achieve the desired effect of cutting or crushing. 3) High efficiency: especially mine party material exploitation, less breakage, finished product rate can be increased 23-fold. 4) Economy: Broken agents use cost far less than other crushing and cutting tools. 5) Use simple: just mix this product with the quantity of water is stirred into a homogeneous paste, then pour hole can be drilled. 6) Free license. 7) and convenient transportation. IV. Usage: how to design and develop a reasonable drilling operation of the program is to use our silent broken agent of the most critical aspects, it is directly related to the crushing effect. Drilling Design: 1) diameter: 3250 mm (the larger the aperture, the greater the resulting swelling pressure, cracking the shorter the time); 2) Pitch: 1540 cm (the smaller the pitch, the shorter the time based on the aperture and the object cracking. of different materials, is about 58 times the aperture such as granite and concrete is about 56 times the aperture, marble and concrete 78 times); 3) hole depth: 85,105%. Please charge before the hole clean of dust or water. 4) row spacing: the distance between rows of holes: 023 (0209 mining engineering side crushed material is generally mined 13) Note: For specific applications (such as large aperture 6090 or special projects) to declare in advance, in order to provide the factory assist in the design of the product or the appropriate action plan. 2. Proportion and amount: water ratio is 2530% expansion agent, for example, 10 kg with 253 kg of water broken agent 3. Mixing and mounting holes: the ratio of good broken agent slowly added to the water, while adding while stirring, until the mixture was stirred into a paste slurry (a stirring preferably not more than 10 kilograms, the better mounting hole), then the stirred the slurry was poured into the wells within 5 minutes. 4. When you want to break a large thickness of concrete, broken can be layered, layer thickness of about 115 is appropriate. For special projects, can be designed oblique holes. For oblique hole or horizontal hole can make use of a catheter loading, or half the feed mix into a paste and knead strip material and then inserted into the hole scratch reality. Four Safety Precautions: Please read and strictly observe the following three "security considerations", otherwise, if you have any accidents during construction, peril: Note (a) In order to avoid fragmentation agent in case of injury when "orifices" people when grout to crack the object to the front, to prohibit any person to look straight holes
