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.
