1, chemical-agent technique.The method is the concrete carbonizing degree of reflection indirectly, and is easy to use, cost is low, but precision is not high, influence factor is many, and can not determine concrete neutralisation reason.
2, heat analysis method.The method can directly be reacted the carbonizing degree of hydrated product, process of the test more complicated.Can only estimate Ca (OH)
2Carbonization, can not estimate the carbonization of C-S-H, sample preparation is complicated, heating up needs cost plenty of time etc., is not suitable for carrying out a large amount of tests.
3, x-ray method.The method is applicable to the laboratory and accurately measures, and exists equally sample preparation complicated, be not easy to lot of experiments, and quantitative accuracy is poor.
4, electron probe microanalysis (EPMA) method.This is mainly used in measuring the microcell carbonization state.
Can find out that from above-mentioned introduction all there is certain defective in existing concrete carbonization detection method, can not satisfy scene, fast and accurate actual testing requirement, therefore propose a kind of CaCO that utilizes in acid solution and the sample to be checked
3Composition is anti-/ should, thereby detect the novel detection device of concrete carbonization degree.This pick-up unit is by detecting the CO that produces after chemical reaction occurs
2Estimate carbonizing degree, solved existing methodical deficiency.But detect carbon dioxide often by sensor, and course of reaction needs by fully carrying out of rocking to guarantee to reflect, acid solution therefore just may occur reacting owing to poorly sealed or spill the situation that causes sensor to be corroded even damage.
Summary of the invention
The utility model provides the novel agent bottle of a kind of better tightness, more reasonable structure for the defective of the acid liquid corrosion sensor that may occur in the concrete carbonization testing process and γ-ray emission leakage.
The technical solution of the utility model is: a kind of concrete carbonization measurement mechanism reagent bottle, be installed in reaction bulb and the formed cavity of doubly-linked sealing-plug, be provided with two independently cavitys in the described reagent bottle, be respectively pressure chamber and solvent chamber, the end that wherein pressure chamber is adjacent with the solvent chamber is enclosed construction, and the other end is the opening that is sleeved on the doubly-linked sealing-plug, and has pressure transmission hole at its sidewall, the closed at both ends in solvent chamber has liquid injection hole at its sidewall.
Especially, length and the reaction bulb of described reagent bottle are suitable with the formed cavity length of doubly-linked sealing-plug.
Especially, described pressure transmission hole and liquid injection hole become an angle of 90 degrees setting with respect to the axis of reagent bottle.
The beneficial effects of the utility model are: at first, the structure of solution cavity can guarantee acid solution the doubly-linked sealing-plug with before reaction bulb is connected not with reaction bulb in powder react; Secondly, the gas that reaction produces only enters the doubly-linked sealing-plug by the pressure transmission hole on the pressure chamber sidewall, can greatly reduce the possibility that the acid solution in the reaction bulb enters the doubly-linked sealing-plug; In addition; the length of reagent bottle and reaction bulb are suitable with the formed cavity length of doubly-linked sealing-plug, can avoid that reagent bottle comes off from the doubly-linked sealing-plug in the process of shaking, and have avoided acid solution to enter the middle opening of doubly-linked sealing-plug; thereby effectively protected sensor, improved product serviceable life.
