Description
Technical field
The present invention relates to a kind of testing of materials, analytical equipment, in particularly a kind of insulation material, halogen system flame-retardant composition measures dress
Put.
Background technology
Building energy conservation is a basic trend of world architecture development in recent years, is also that of Contemporary Architecture science and technology is new
Growth point.Under national energy-saving reduces discharging the guidance of policy, external wall is forced to do exterior-wall heat insulation, to reach energy-saving and emission-reduction
Purpose, due to good heat insulating ability with use persistence, building thermal insulation material in the market is with EPS and XPS (all
For polystyrene material) it is main.But, this kind of insulation material belongs to inflammable material, in order to improve fire protecting performance, it is necessary to
Adding fire retardant in raw material, the halogen flame such as the most fluorine-containing (F), chlorine (Cl), bromine (Br) uses more, because of
This is currently badly in need of a kind of can accurately analyzing the device of halogenated flame retardant content in insulation material.
Summary of the invention
The present invention solves that technical problem present in known technology provides halogen system flame-retardant composition in a kind of insulation material to measure
Device, this device can accurately analyze the content of halogenated flame retardant in insulation material.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: halogen in a kind of insulation material
It is flame-retardant composition determinator, including Molotov cocktail, platinum filament basket and porous glass plate absorption bottle, in the lower side of described Molotov cocktail
Wall is provided with oxygen inlet, is provided with bottle cap at the top of described Molotov cocktail, and described platinum filament basket hangs on described bottle cap, in institute
Platinum filament geometrical clamp it is fixed with in stating platinum filament basket；Being provided with exhanst gas outlet in the upper portion side wall of described Molotov cocktail, described flue gas goes out
Mouth is connected with described porous glass plate absorption bottle by flexible pipe, is loaded with absorbing liquid in described porous glass plate absorption bottle.
Described porous glass plate absorption bottle has the two-stage of series connection.
Described oxygen inlet and described exhanst gas outlet are equipped with valve.
The present invention has the advantage that with good effect: use Molotov cocktail combustion decomposition sample, uses porous glass plate absorption bottle
Absorbing flue gas, quantitative analysis after constant volume, through checking experimental result accurate, objective, reliable.Meanwhile, adopt in the present invention
By Molotov cocktail and the separate structure of porous glass plate absorption bottle, both can guarantee that burning gases, all by absorbing liquid, improved and absorb
Efficiency, turn avoid and be inverted by Molotov cocktail, and operability strengthens.Oxygen is continually fed into, it is ensured that sample can fully burn,
Improve the degree of accuracy of mensuration.Use the series connection of two-stage absorbing liquid, ensured that the halogen in burning gases absorbs completely.And
Present configuration is simple, and definite principle, easy to operate, low cost, DATA REASONING is accurate, it is also possible to for plant, life
The pretreatment process of the samples such as thing, coal, diesel oil, discarded object and petroleum and petrochemical industry product, so analyze the F in sample, Cl,
Br, P, S, N, Se various element.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, Molotov cocktail；2, platinum filament basket；3, oxygen inlet；4, porous glass plate absorption bottle.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing
Describe in detail as follows:
Referring to Fig. 1, halogen system flame-retardant composition determinator in a kind of insulation material, including Molotov cocktail 1, platinum filament basket 2 and many
Hole glass plate absorption bottle 4, is provided with oxygen inlet 3 on the lower sides of described Molotov cocktail 1, sets at the top of described Molotov cocktail
There are bottle cap, described platinum filament basket 2 to hang on described bottle cap, in described platinum filament basket 2, are fixed with platinum filament geometrical clamp；Described
The upper portion side wall of Molotov cocktail 1 is provided with exhanst gas outlet, and described exhanst gas outlet is by flexible pipe and described porous glass plate absorption bottle 4
It is connected, in described porous glass plate absorption bottle 4, is loaded with absorbing liquid.
In the present embodiment, described porous glass plate absorption bottle 4 has the two-stage of series connection.At described oxygen inlet 3 and described cigarette
It is equipped with valve in gas outlet.
The principle of the present invention:
In the halogen flame of insulation material, halogen is bonded together with organic molecule, in order to measure halogen in insulation material
Element (F, Cl, Br) content, needs flame retardant molecule structural deterioration, makes halogen (F, Cl, Br) free the most again
Measure.The present invention uses decomposition by combustion, completes combustion decomposition in Molotov cocktail, uses porous glass plate absorption bottle to carry out cigarette
Aspiration is received, and finally reaches the purpose of quantitative analysis.
The application process of the present invention:
Sample is cut into strip, puts into platinum filament basket 2, and clip with platinum filament geometrical clamp；Put into the Molotov cocktail 1 of full oxygen
In burn, during sample combustion, be continually fed into oxygen, make burning complete, component to be measured from sample matrices with
Oxide form discharges, at exhanst gas outlet two porous glass plate absorption bottles 4 of series connection of Molotov cocktail, porous glass plate absorption bottle
Absorbing liquid in 4 absorbs flue gas, carries out ion chromatography subsequently.
Although the preferred embodiments of the present invention being described above in conjunction with accompanying drawing, but the invention is not limited in above-mentioned
