Shaoxing silent broken agent, Shaoxing rock expanders how to buy? How much the price? Action action principle carbatex static crushing process agent carbatex static crushing agents produce expansion force is a chemical reaction process, therefore, research carbatex static crushing agents first study the chemical reaction process from the start. Thermodynamic method to study its main reaction, the reaction can be obtained direction and equilibrium constants; carbatex static crushing agents expansion pressure was the result of volume increases arising after the reaction. Transfer of the reaction process research material change in volume before and after the reaction, the expansion mechanism carbatex static agent can be broken and the resulting volume expansion conditions, further guidance carbatex static pressure increase of demolition agent expansion. In addition, the reaction carbatex static crushing agent is an exothermic reaction once started, the heat will continue to increase. When the heat loss is less than the heat generated by the reaction temperature will rise, accelerating the reaction rate, it will likely lead to the punching phenomenon. With the progress of the reaction, the temperature gradually decreased, but the expansion pressure continued to grow, and carbatex static crushing agents affected by ambient temperature is very large, in the winter cold season react slowly, sometimes useless; in the summer heat Shi Yi produce punching. Therefore, to study the reaction is exothermic, to increase the reaction rate carbatex static crushing agents and prevent the occurrence of punching is important. The basic chemical reaction Formula 1 carbatex static crushing agents present, the main ingredient carbatex static crushing agent is calcium oxide. Calcium oxide and water reacts with calcium hydroxide in the release heat, while its volume increases. Jiaze static crushing agents is the use of this chemical reaction and swelling pressure crystallization of calcium hydroxide to disrupt development resulting brittle materials such as rock and concrete. The basic chemical reaction is as follows: CaO ten H 2 O → Ca (OH) 2 + 64.8kJ can be seen from the formula, which is an exothermic reaction. Transfer calcium and water mixture of two substances oxidation reaction occurs immediately transfer process two types of material: 1) water molecules into CaO particles inside, and with the hydration reaction; 2) the hydration reaction product of water-filled space to the original transfer . If the former and the latter to adapt, that is the transfer speed when the hydration rate and hydration products are equal, CaO - the volume of water system does not swell, however, due to the structural characteristics of CaO, that a large surface area, the rate of hydration Soon, the hydration rate is greater than the transfer speed of hydration products, this time, the reaction product is not around CaO particles move away, but there's a lot of reaction and produced, and these new reagents will exceed the original reaction layer , the particles create mechanical jump, thereby causing volume expansion, resulting in swelling pressure, the constraint media damage. In the absence of constraints, calcium oxide broke into the loose powder. 3 reflect the changes before and after the demolition agent Jiaze static pressure of the expansion is due to produce volume after volume increase caused by the reaction. When the reaction of CaO and water to form solid volume Ca (OH) 2 in the solid volume under certain conditions than 97.92% CaO increases. Solid volume increases, the solid volume increment of void volume and over space CaO water systems, causing increasing CaO volume expansion pressure. Quicklime hydration reaction in the free state is not bound by the expansion, the volume will increase 2 to 3 times. Under constrained conditions, the expansion of smaller size. When the binding is very large, the volume does not change, that does not produce expansion, which is in practice often appears carbatex static demolition agent into the situation blasthole stalled. The reason for this are: First, let's discuss the reactants and products from the molar volume change. Jiaze static crushing agent is the use of lime hydration reaction, but the molar volume at standard conditions of its volume and product comparison can be seen, not in all cases, will have a volume expansion. We discussed in detail below what happens volume expansion. The following reaction formula shows the product of the molar volume of reactants and specific gravity data. CaO + H 2 O → Ca (OH) 2 + 64.8kj molar volume: 16.764cm 3, 18.069cm 3, 33.056cm 3; specific gravity: 3.2g / cm 3 ~ 3.4g / cm 3, 1.0g / cm 3, 2.1 g / cm 3 ~ 2.3g / cm 3 from the data listed above, the molar volume of the product was 33.065cm 3, and the molar volume of the reactants is 16.764 + 18.069 = 34.833cm 3, after the reaction volume should be smaller, rather than increases. This seems to be in contradiction with the actual situation. This is because the molar volume is the volume when the molecular closest packing, and static crushing agents in carbatex practical application is its apparent size, that is to say, in general, carbatex static crushing agents lime hydration reaction The product is difficult to achieve the molecular state of closest packing, because in the dry state, the resulting calcium hydroxide very large surface area, not the closest packing state, therefore, on the performance of the volume expansion. In contrast, in the presence of a large amount of water, such as in an aqueous solution, the reaction of calcium oxide with water to form calcium hydroxide, which smaller size, without generating an expansion force. Under normal water conditions (dry, not in aqueous solution), it is used to measure the density of calcium oxide and calcium hydroxide, rather than gravity. Lime calcination of calcium carbonate is formed, since the CO 2 to escape, resulting in a lot of pores, maintaining the illusion of calcium carbonate, calcium oxide, which is slightly larger than a bulk density, and its 3.2 g / cm 3 ~ 3.4g / cm 3 of proportion far. Calcium hydroxide in the dry state, the density is very small, only about 1. Such lime hydration reaction in (dry state) on the performance of the volume increase of the phenomenon. When the external binding is very large, forcing the calcium hydroxide generated the bulk density close to its share of the volume produced is more and more small, do not even produce expansion. 4 exothermic reaction when the temperature is less than 100 ℃, temperature increase the heat released; when the temperature exceeds 100 ℃, calcium oxide reacts with water vapor to emit more heat; when the temperature is increased further, the heat released gradually decreases. This can be seen, the reaction once started, the heat will continue to increase; when the heat loss is less than the heat generated by the reaction temperature will rise, accelerating the reaction rate, it will likely lead to the punching phenomenon. Also can be seen from Table 1, carbatex static crushing agents affected by the ambient temperature is very large, in the cold winter season slow reaction, sometimes even useless; in the summer time and easy to produce hot punching. 5 Conclusion By using the above method is simple thermodynamic analysis of static demolition agent Jiaze main reaction can draw the following conclusions: 1) If you want to increase the expansion pressure, it is necessary to improve the density of calcium hydroxide, while reducing the water-cement ratio, so Jiaze static crushing agents in a dry state; 2) If you want to increase the reaction rate, it is necessary to increase the activity of the reactants or reaction temperature; 3) To prevent the occurrence of punching, we need to add water vapor can strongly absorb in the subsequent reaction in the water released from the material. More than 3 conclusion that the principle of design carbatex static demolition agent followed when we developed the program.
