Description
Technical field: the present invention relates to a kind of detect the gas chromatography of organic components in volatilization gas.
Background technology: nuclear power Half Speed steam turbine generator applies a large amount of insulant, in the fabrication process including paint
Glue class, sheet material class, glass fibre class, rubber class etc., part epoxy can add amine curing agent, and bandage tied rope can add
Entering the wetting agent containing amino, along with the longtime running of unit, these Ammonia Organic substances may evaporate into inside unit other
Material corrodes, thus extreme influence electrical machinery life, the method not detecting corrosive gas before this, therefore unit
There is hidden danger in long-term normal operation.
Summary of the invention: it is an object of the invention to provide and a kind of detect the gas chromatographic analysis of organic components in volatilization gas
Method, it is possible to effectively detect the composition of insulant volatilization gas, and the insulant choosing non-volatile corrosive gas is carried out
Manufacture, it is ensured that the safe operation of motor.
The technical scheme is that
A. firstly the need of carrying out insulant according to actual process heating and collect the gas volatilized；
B. with nitrogen, the gas in gas collecting bottle is transferred in test tube to be measured；
C. carry out separating analysis to gas by chromatography of gases analytic process, gas to be measured is imported to chromatography of gases mass spectrum connection
With in instrument, the chromatographic column in gas chromatograph is for separating the critical component of mixing determinand, chromatographic column in gas chromatograph
In containing fixing phase, i.e. there is the adsorbent of high surface area, after multi-component biased sample enters chromatographic column, due to adsorbent
Different to the absorption affinity of each component, after certain time, each component speed of service in the chromatography column is also the most different, absorption
The weak component of power easily is desorbed, and leaves chromatographic column at first and enters detector, and the strongest component of absorption affinity is the easiest
Being desorbed, the most finally leave chromatographic column, so, each component is able to the most separated from one another, and order enters detection
Device is detected, records；
D. by chromatographic control, the architectural feature shown according to result of the test, thus it is speculated that go out that this type of material contains like base
Group.As structure contains silylation, epoxide and phenyl ring, then this type of matter-pole is like siloxanes, and siloxanes is chromatographic column
One of composition, in the case of usual collection capacity is less, the group in the detected volatile substance of this type of material, test can be got rid of
Interference；As in fruit structure containing amido, and by chromatographic control, group is like acetamide, and acetamide must not be instrument color
The one of spectrum post composition, therefore acetamide must for one of the composition of survey volatile matter, and the material containing acetamide is most
There is corrosivity, then just to focus more on the attached attribute of material according to actual condition when material selection.With crossing volatilization
The qualitative analysis of gas, the attached attribute of Knowing material itself, do not interfere with electromotor with guarantee the most properly functioning, and be new
Developing material gives a hand.
The present invention is technically characterized by comprising the steps as follows:
1) for nuclear power end banding material, the existence to specifying group is identified
Conventional analytic process, is only capable of the feature for group itself to analyze the type of group, and the present invention is directed to nuclear power
End banding material glass squeeze, carries out the collection of hot volatilization gas to it, by chromatography of gases analytic process to gas to be measured
Group detect, checking material whether there is corrosivity.
2) chemically component layers surface analysis current material
Chromatography of gases analytic process is to start with from material body, detects its composition group, by composition radical species and group
Composition form analyzes the performance that this material may possess further, finally from material essence Knowing material performance, distinguishes further
Materials application is in the feasibility using position.
3) explore for new material
Chromatography of gases analytic process can also be used for material and explores, and according to the actual requirement of production technology, the anti-material requested that pushes away should
Some performances and manufacturability, form group analysis from material, carries out theory analysis, and in selecting electromotor, diverse location is the suitableeest
Material, substantially reduce the number scientific research engineer testing, reach maximum Expected Results with the shortest time.
The present invention greatly advances the paces of nuclear power supporting insulant production domesticization, and nuclear power End winding is from bar insulation
To fixtures such as supporting insulation, though material high temperature resistant, high performance, but in there is corrosive gaseous environment, its life-span
Inevitable greatly shortening.Therefore fixing in materials process choosing colligation, whether material has corrosivity becomes nuclear power end and joins
What cover material was chosen one examines greatly emphasis, uses the chromatography of gases analytic process glass fiber for nuclear power end banding of this patent
Goods (restrict, carry) and part bonded adhesives, the volatile matter under the high temperature of nominal situation has carried out analyzing qualitatively, has got rid of and replace
Change and wherein volatilized acidity, corrosivity etc. there is the material of destructive performance, it is ensured that the safety of nuclear power generating sets end banding
Property and persistency.This patent identifies material exploration from material and all gives help greatly, significantly improves scientific research efficiency, with
Time also ensure that the safety and reliability that material uses in the unit.
Fig. 1 is heater
Fig. 2 is the method collecting gas
Detailed description of the invention:
A. such as Fig. 1, it is necessary first to carry out heating and collecting volatilization in gas collecting bottle 1 according to actual process by insulant 2
The gas gone out；
B. such as Fig. 2, from air inlet end 3 nitrogen injection of gas collecting bottle, after being heated by material with blind enema, volatilization gas is from giving vent to anger
End 4 is transferred in test tube to be measured；
C. carry out separating analysis to gas by chromatography of gases analytic process, gas to be measured is imported to chromatography of gases mass spectrum connection
With in instrument, the chromatographic column in gas chromatograph is for separating the critical component of mixing determinand, chromatographic column in gas chromatograph
In containing fixing phase, i.e. there is the adsorbent of high surface area, after multi-component biased sample enters chromatographic column, due to adsorbent
Different to the absorption affinity of each component, after certain time, each component speed of service in the chromatography column is also the most different, absorption
The weak component of power easily is desorbed, and leaves chromatographic column at first and enters detector, and the strongest component of absorption affinity is the easiest
Being desorbed, the most finally leave chromatographic column, so, each component is able to the most separated from one another, and order enters detection
Device is detected, records；
D. by chromatographic control, the architectural feature shown according to result of the test, thus it is speculated that go out that this type of material contains like base
Group.As structure contains silylation, epoxide and phenyl ring, then this type of matter-pole is like siloxanes, and siloxanes is chromatographic column
One of composition, in the case of usual collection capacity is less, the group in the detected volatile substance of this type of material, test can be got rid of
Interference；As in fruit structure containing amido, and by chromatographic control, group is like acetamide, and acetamide must not be instrument color
The one of spectrum post composition, therefore acetamide must for one of the composition of survey volatile matter, and the material containing acetamide is most
