Expansion cracking agent (also known as silent Crushing agent , Static Crushing agent , rock breaker, etc.),
It is a kind of powdery construction material that can break rock and concrete without use. Its main component is quicklime (i.e. calcium oxide), and it also contains some compound catalysts mixed in a certain proportion. The principle of breaking the medium is to use the static state installed in the medium borehole Crushing agent Hydration reaction occurs after adding water to make Crushing agent The crystal deforms to produce volume expansion, so that the expansion pressure (up to 30Mpa~50Mpa) is applied to the wall, and after a period of time, it reaches the feng value to break the medium. It can be widely used in silent crushing and demolition of concrete structures and rock mining, which solves the problem that crushing is not allowed to be used in the construction of crushing works and must be Rock fragmentation The construction process of crushing is also very simple: for the crushed medium, after reasonable crushing design (determination of hole diameter, hole spacing, etc.) and drilling Crushing agent Use appropriate amount of water to make a flowing slurry and directly inject it into the borehole. After half an hour or several hours (mainly determined by water cement ratio), the medium (rock ——The tensile strength is 5~10Mpa or concrete - the tensile strength is 2~6Mpa) will burst and break.
Characteristics of expansive rock cracking agent:
（ 1) Safe and easy to manage. static state Crushing agent It is non explosive dangerous goods. No special type of work such as crushing is required during operation. Crushing agent It can be purchased, transported and used as other ordinary goods.
（ 2) Environmentally friendly materials. Silent, vibration free, flying stone free, gas free and dust free in use, it is an internationally popular pollution-free environmental protection product.
（ 3) According to the crushing requirements, design appropriate hole diameter, hole spacing and angle to achieve the desired effect.
