Factory wholesale Jinhua silent expanders, rock crushing agents operating instructions Jiaze price performance testing performance testing of static demolition agent Jiaze static crushing agents include swelling pressure test rock and concrete cracking test in two parts. The expansion pressure is an important indicator of performance demolition agent Jiaze of static. The expansion pressure is measured Jiaze static demolition agent development process is an indispensable part of, but also a very important tool. The concrete cracking test is to directly carbatex static demolition agent used in the tests. By observing cracking time a comprehensive assessment of the expansion pressure can Jiaze static crushing agents and reaction speed, and expansion pressure test compared carbatex reflect the merits of static crushing agents more directly. But concrete cracking test is not a substitute swelling pressure test, because of the size it can not give quantitative expansion pressure. Therefore, the expansion pressure testing and concrete cracking test are complementary, they are static demolition agent performance test carbatex indispensable part. 1 Jiaze static stress tests and analysis of demolition agent expansion pressure is an important indicator of performance demolition agent Jiaze of static. The expansion pressure is measured Jiaze static crushing agents developed during an extremely important tool. Ingredient Jiaze static crushing ratio and production conditions, a large part is determined by the expansion pressure. Thus, in the development process carbatex static crushing agents, we use hydraulic pressure measurement means expanding pressure carbatex static crushing agents studied for a number of tests. In order to understand the impact of various factors on carbatex static crushing agents, using different conditions on the expansion pressure carbatex static crushing agents to be tested, in order to understand the research and development of resistance to weathering carbatex static crushing agents, that is, different ambient temperature on swelling pressure the impact of expansion at different seasons stress test. 2 expansion pressure test expansion pressure test values ??carbatex static crushing agent is affected by many factors. In order to understand the impact of these factors on the expansion of broken agent Jiaze static pressure, we continue to take a different water-cement ratio, with different pore sizes and different dosage and other conditions for the development of the carbatex static crushing agents several tests and research. In order to understand the performance of different carbatex products, we are commercially available carbatex products 1, 2 and the commercial product carbatex developed its own static crushing agents Jiaze expansion pressure testing. In order to understand the effects of different amounts of charge Jiaze static crushing pressure of the expansion agent, each for different static crushing agents Jiaze expansion pressure testing. Water-cement ratio of 2.1 Jiaze static crushing impact of Expanded pressure test sample was developed carbatex static crushing agent loading dose of 200 g, water-cement ratio of 0.3, 0.34 and 0.38, can be drawn, water cement ratio has broken for the expansion pressure carbatex static agent a certain impact, as water-cement ratio increases, the expansion pressure carbatex static crushing agents decreases, water-cement ratio smaller carbatex static crushing agents expansion pressure greater. However, the water-cement ratio carbatex static crushing agents can not be too small, water-cement ratio is too small, although you can increase the expansion pressure carbatex static crushing agent, but the impact of construction performance carbatex static crushing agents. Therefore, we must control the water-cement ratio is good carbatex static crushing agents. Construction of water-cement ratio carbatex developed static crushing agent is 0.3. In this case, it is better workability, the expansion pressure is relatively large. 2.2 Charge rate on the test sample specimen for carbatex expansion pressure static broken agent 1, Sample 2, Sample 3, Sample 4 and Sample 5 was developed carbatex static demolition agent, the dose was 150 g, 180 g, 200 g, 230 g and 260 g, the expansion pressure - time relationship. From the experimental results, at a certain water-cement ratio and a certain temperature conditions, with increasing dose, the expansion pressure carbatex static crushing agents also continued to grow. Almost doses proportional to its demolition agent Jiaze static pressure expansion can be achieved. Expansion pressure, the greater its undulating curves; expansion pressure is smaller, which curves gently undulating more. 2.3 expansion pressure comparison test sample different carbatex static crushing agents newly developed 6 Jiaze static demolition agent, Sample 7, 8 for the two commercially available general carbatex static demolition agent, dose are 200 g. From the experimental results, under the same conditions, the newly developed swelling pressure carbatex static crushing agents are commercially available common static pressure of 2-3 times broken agent, up to nearly 120 MPa. In addition, the development of the reaction rate carbatex static crushing agent than ordinary static crushing agents fast, just 7 h will be able to achieve a higher expansion pressure, and ordinary carbatex static crushing agents will need more than 30 h. 2.4 In order to understand the impact of weather resistance test weathering performance and environmental temperature developed new carbatex static crushing agents to carbatex static crushing pressure of the expansion agent, respectively, in the spring, summer and winter, the same kind carbatex static crushing agents were expanded stress tests, the static crushing agents carbatex weather is good, its swelling pressure changes little with temperature. 3 concrete cracking experiments using the same aperture, cracking time they use are different, the number of multi-aperture, its expansion pressure distribution, the expansion pressure increases. When the aperture to increase the number of one of its many broken relatively short time. But from the economic view, should select a reasonable number of holes, diameter and spacing. From the experimental results, compared with the conventional static demolition agent, the new agent carbatex static crushing expansion pressure, the reaction speed. It can also be seen from the experimental results, the cracking experiments carried out on the same test block, when the same number of holes, large pore cracking time is short; be cracking on the concrete specifications of the same number of holes much less than the number of holes cracking time short, that is to say when the hole spacing to a certain distance, the concrete cracking becomes very difficult. Sometimes you need more than a few days time to cracking. That said swelling pressure 明嘉泽 static crushing agents are limited. So, carbatex static crushing agents are generally used for crushing concrete. In all experiments were not there punching phenomenon, easy to operate, there is no case of loss of effect and not crack appears. And all carbatex static demolition agent in the storage period of time, the reaction speed is increased, which is better than the performance of ordinary static crushing agents.
