Expansive cement Hangzhou silent broken agent, constituent materials and essential performance of Hangzhou rock expansive wholesale price Ge Jiaze silent broken agent in an industrial building process, our products have great development carbatex market, in our concrete building process played a very important role. Long 沙嘉泽 Building Materials Technology Co., Ltd. silent expanders, static crushing agents are widely used in rock crushing cutting, mining field, reinforced concrete crushing, tunnels, pit construction, etc., to avoid explosion demolished a significant effect, safe and reliable! Jiaze silent broken agent for concrete or reinforced concrete structures removed. All kinds of rock, such as marble, granite, jade mining and cutting, the finished product rate increased by 2 to 3 times. It can be combined with controlled blasting or hydraulic gun, concrete building demolition or breaking rocks. Particularly applicable in the case should not be used zhayaobaopo, crushing or demolition. The use of safe, efficient, uninterrupted traffic, no downtime. Jiaze silent broken agent is calcium carbonate and calcium oxide powder composed of gray matter 0--250 project, even after mixing with water and poured into the hole to lay, use it to generate the volumetric expansion of hydration, swelling pressure up to 500 kg / cm, when the compressive strength of concrete or rock or shear strength of less than 500 kg / cm when it reached the broken cracks purpose. This product has no pollution, no danger, silent, no vibration, no flying rocks, operate and simple, so that was demolished was slowly cracks. Silent expanders (silent broken agent) to use when using the silent expanders, broken objects in general a pore size of 2.8-4.0cm, pitch 20-30cm; hole depth according to the thickness of the material may be broken. But not pierced bottom must keep 10-20cm. 1, now silent expansive water and press (1: 3) ratio (ie a packet of silent broken agent 3-4 kg of water Note: High temperatures suitable dilute a little more points, low temperatures a little thick), into the container with wooden stir into a flowable slurry (paste type). 2, the stirred slurry was injected into the inflatable object hole. Slurry stirred expansion, such as high temperatures generally require 10-20 minutes to complete filling, otherwise the filling and bursting liquidity effect will be significantly reduced. 3, again not too much slurry stirred expansion should be based on the number of workers and material may be broken. 4, filling holes must be dense, level (ie lift boreholes) or inclined holes to plug opening, use a dry thick clay twist plunge hole in tamping bar.
