preparation example Construction

[0090] The preparation methods of graphene include mechanical exfoliation method, epitaxial growth method, chemical vapor deposition method, chemical synthesis method, graphene oxide reduction method and longitudinal cutting carbon tube method.

[0091] Mechanical exfoliation method: Graphene is separated from graphite by micromechanical exfoliation method, and ultrasonic exfoliation of graphite in liquid phase is another commonly used method for exfoliating graphite.

[0092] Epitaxial growth method: use high temperature (1200-1500°C) sublimation to remove silicon atoms from the surface of single crystal silicon carbide (SiC), so as to obtain epitaxially grown graphene.

[0093] Chemical vapor deposition method: Chemical vapor deposition method refers to cracking carbon sources (such as hydrocarbons) at high temperature and depositing them on the surface of solid substrates, which are usually transition metals such as Ni and Ru.

[0094] Graphene oxide reduction method: curre...

Embodiment approach 1

[0114] Embodiment 1: Embodiment 1 of the present invention provides a carbon dioxide heating powder composition, which is characterized in that it includes at least an organic acid, a metal powder, an oxidant, an ammonium compound, and ash powder.

Embodiment approach 2

[0115] Embodiment 2: Same as Embodiment 1, the difference is that the weight ratio of organic acid, metal powder, oxidant, ammonium compound, and ash powder in the carbon dioxide heating powder composition is: 5-15:0.5-2:40 ~60: 10~20: 3~10.

Abstract

The invention relates to the technical field of explosion, in particular to a carbon dioxide heating powder composition, at least comprising organic acid, metal powder, an oxidant, an ammonium compound and plant ash. The carbon dioxide heating powder composition has the advantages of high explosion speed, zero noise, zero dust and the like; the requirement for quick construction can be met, and explosion efficiency can be improved; the carbon dioxide heating powder composition is non-inflammable, non-explosive and nontoxic and is very safe to transport, store and use, and the defects of detonators and explosives are overcome; there is no toxic and high-temperature matters produced and zero gas explosion caused in the explosion process; small blasting vibration is caused, and the composition is simple to make and low in cost; a blasting method is simple to use and has no special requirement on construction operations, zero flame and low temperature are caused in blasting, and therefore, the advantages of the composition are achieved.

Description

technical field [0001] The invention relates to the technical field of blasting, and more specifically, the invention relates to a carbon dioxide heating powder composition used in the technical field of blasting. Background technique [0002] At present, more than 95% of coal seams with high gas and outburst mines in my country are low-permeability coal seams, and two-thirds of the coal resources are below 1,000 meters, accounting for 53% of the total coal resources. The average mining depth is 20m per year. It is expected that the depth of many coal mines will reach 1000m to 1500m in the next 20 years. After the mining depth increases, the gas content will increase, and the air permeability of the coal seam will decrease. Therefore, it is crucial to find an efficient, economical and widely applicable blasting method. Significance. [0003] High-pressure gas blasting is a kind of blasting without explosives. In the early 1960s, some developed countries such as the United Sta...
