Technical field
The present invention relates to fever and gas exhausted material fields, in particular it relates to which a kind of carbon dioxide that is suitable for is exploited
The clean and effective heat production gas generating agent and its manufacturing method of device heater.
Background technique
Carbon dioxide exploitation device is metal tube, the heater that can repeat to fill liquid carbon dioxide by a high intensity
The composition such as (heat generating device), filling body and level pressure Guo Neng mechanism.Exploitation device is placed in coal body drilling, is started using exploder
Heater heats pressurization for internal liquid CO 2, and pressure persistently increases compressing level pressure Guo Neng mechanism in pipeline, makes wherein
Level pressure let out can piece rupture, release volume expand 600 times, pressure be more than hundred megapascal carbon dioxide gas, progress explosion fall
Coal.The blasting method effectively prevents causing gas combustion or explosion accident due to generating open fire because blowing out, and is particularly suitable for high watt
The mine coal blasting of this and coal and gas prominent, is conducive to Safety of Coal Mine Production.
The proof test of Huaibei Coal Mines in 2007 and cardox company cooperation development carbon dioxide exploitation device, exploits device table
Good Security and demolition effect are revealed.But it is disposable production that carbon dioxide, which exploits heater (heat generating device) in device,
Product, rely primarily on import, and higher cost limits it and popularizes in an all-round way and apply in coal mine.The domestic heat generating device of developing low-cost,
Reducing use cost seems especially urgent.
Summary of the invention
Technology of the invention solves the problems, such as it is to overcome the deficiencies of the prior art and provide that a kind of safety and stability, heat production is high, produces
Gas rate is high, gas ingredients clean, the cleaning heat production gas generating agent that residue is few and nontoxic, cost performance is high, is suitable for carbon dioxide
It exploits device heater (heat generating device).
The present invention also provides the manufacturing methods of above-mentioned cleaning heat production gas generating agent.
The present invention also provides the application methods of above-mentioned cleaning heat production gas generating agent.
The technical solution of the invention is as follows: a kind of clean and effective heat production gas generating agent, it is characterised in that including following quality
Percentage component:

Invention also provides the manufacturing methods of above-mentioned cleaning heat production gas generating agent, including the following steps:
(1) material after sieving, drying is added to the mixer after weighing proportionally, such as V-Mixer, multidirectional fortune
Dynamic mixing machine, stereo mixing machines etc..
(2) 20 mesh ~ 80 mesh standard sieves will be crossed by mixed powder, according to the requirement to the medicament difference starting time, medicine
Powder uses after directly loading the tablet for using or being pressed into different-thickness and diameter.
A kind of application method of cleaning heat production gas generating agent of the invention is that directly pulverulent mixture is pressed into paper tube to make
With or be fitted into paper tube and use after being granulated.
The advantages of the present invention over the prior art are that:
(1) of the invention compared with now commonly using alkali type nantokite and perchlorate etc., have factor of created gase is higher, aerogenic composition more
The advantages that after clean, burning without residue, it is more suitable for the semiclosed environment of person works.
(2) metallic compound that there is catalytic action to ammonium nitrate is added in the present invention, adjustable heat production gas generating agent
Ignition performance and burn rate.In liquid CO 2 High Voltage atmosphere, the addition of a small amount of catalyst can regulate and control in very wide range
The reaction speed of heat production gas generating agent.Compared with existing general invention, metallic compound dosage is minimized.
(3) copper oxide and copper chromite being added in the present invention are not involved in reaction, and burning front and back does not change, do not influence
Gas component；Potassium hyperchlorate also acts as the effect of oxidant in addition to as catalyst, is changed into after burning corrosion-free, easy cleaning
KCl has no adverse effect to aerogenic composition.
(4) kaolin for being not involved in reaction or clay or silicon nitride being added in the present invention, can increase the self-adhesion of medicinal powder
Property, so that medicament is easy to compression molding.Especially the use of silicon nitride can make coat tablets bright and clean, prevent tablet from clinging tablet press machine mould
Tool improves demolding performace.
(5) heat production gas generating agent of the present invention, according to the requirement of use environment and starting speed, uniformly mixed medicinal powder and compacting
Molding tablet may be used to heat-producing unit, adaptable, application form multiplicity.
In short, providing the cleaning heat production gas generating agent and manufacturing process for carbon dioxide exploitation device heat-producing unit, manufacture
Clean and effective heat production gas generating agent out has high safety, and extremely difficult generation chemically reacts under normal pressure, can pass through electricity under high pressure
Signal causes；Safety and stability, heat production is high, factor of created gase is high, gas ingredients cleaning, that residue is few and nontoxic, cost performance is high etc. is excellent
Point.For the present invention using guanidine nitrate as fuel, ammonium nitrate ensures combustion gas, the high production for producing gas heat production agent cleaning as oxidant
Heat and factor of created gase, high thermal stability and safety, medicament is difficult to light under normal pressure, but again can vigorous combustion under high pressure.Metal
The addition of compound improves ignition performance, shortens ignition delay time, thus, guarantee the effective work for producing gas heat production agent.
The security performance height of gas heat production agent and easy to form is produced based on the present invention, it can be loaded with powder-form and be used, may be made as
Sizes tablet, medicine ball carry out filling use, have widened the use scope of medicament.
