Abstract
The utility model relates to a sulfite testing device for gypsum boards. In the device, one end of a reducer is connected with a flat-bottomed flask; one end of a guide tube arranged on the reducer is placed in the flat-bottomed flask, and the other end of the guide tube is connected with the exhaust tube of a gas washing tube through a connecting tube; the other end of the reducer is connected with one end of a straight condenser tube; the other end of the straight condenser tube is connected with a straight separating funnel; a bottle plug is arranged on the other end of the straight separating funnel; and the guide tube arranged on the straight condenser tube is connected with one tube orifice of an absorbing tube through a connecting tube, and the other tube orifice of the absorbing tube is connected with an air sampler. The sulfite testing device has the characteristics of adopting an air sampling pump to absorb sulfur dioxide gas given off after the sample is dissolved in an acid, measuring by spectrophotometry, reducing consumption of the acid, saving cost, reducing test time, ensuring operating safety and convenience and reducing pollution to the environment.
Description
Technical field
The utility model relates to a kind of pick-up unit that is used for building materials, particularly a kind of Arius hydrochlorate determinator that is used for plasterboard.
Background technology
Contain a certain amount of sulphite in the plasterboard, under acid wet condition, sulphite is emitted SO
2, SO
2Be a kind of colourless gas that penetrating odor is arranged, very harmful to human body, sulphite also is easy to the sulfide reaction and generates elemental sulfur in addition, and elemental sulfur has certain corrosive attack to metal.This makes when plasterboard uses under acid wet condition, can produce certain negative effect to environment.So far,, set up fairly perfect sulphite analytical approach in the food additives field, but in building productses such as plasterboard check field, less about the report of sulphite analytical approach and pick-up unit.And the sulphite determinator of food generally all will feed nitrogen, and the reaction time is also long, is unfavorable for the quick test of sample Central Asia sulphates content.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of nitrogen that do not need to feed, and can satisfy the Arius hydrochlorate determinator that is used for plasterboard of fast detecting.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of Arius hydrochlorate determinator that is used for plasterboard, it is characterized in that: comprise flat bottom flask, speed reduction unit, condenser west tube, be provided with the straight type separating funnel of regulating piston, absorption tube, air sampler, scrubber tube, connecting pipe, bottle stopper, described speed reduction unit one end is connected with described flat bottom flask, conduit one end that is provided with on the speed reduction unit places flat bottom flask, the other end of conduit is connected with the escape pipe of described scrubber tube by described connecting pipe, the other end of speed reduction unit is connected with described condenser west tube one end, the other end of condenser west tube is connected with described straight type separating funnel, the other end of straight type separating funnel is provided with described bottle stopper, the conduit that is provided with on the condenser west tube is connected with a mouth of pipe of described absorption tube by connecting pipe, and another mouth of pipe of absorption tube is connected with described air sampler.
Characteristics of the present utility model are: this device does not need to feed nitrogen, adopt the air sampling pump to absorb the sulfur dioxide gas that discharges after the sour sample dissolution, adopt spectrophotometry, reduced sour use amount, saved cost, shortened the test duration, easy-to-operate reduces environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Arius hydrochlorate determinator that is used for plasterboard comprises flat bottom flask 1, speed reduction unit 2, condenser west tube 3, is provided with straight type separating funnel 4, absorption tube 5, air sampler 6, scrubber tube 7, the connecting pipe 8 of regulating piston 4-1, bottle stopper 9.
One end of speed reduction unit 2 is inserted in the bottleneck of flat bottom flask 1, the end of the conduit 2-1 that establishes on the speed reduction unit 2 places flat bottom flask 1, the other end of conduit 2-1 is connected with the escape pipe 7-1 of scrubber tube 7 by connecting pipe 8, one end of condenser west tube 3 is inserted in the other end of speed reduction unit 2, the other end of condenser west tube 3 socket-connects together with an end that has the straight type separating funnel 4 of regulating piston 4-1, bottle stopper 9 is filled in the another port of straight type separating funnel 4, with condenser west tube 3 for the conduit 3-1 of one is connected with a mouth of pipe of absorption tube 5 by connecting pipe 8, another mouth of pipe of absorption tube 5 is connected with air sampler 6 by connecting pipe 8.
Using method: water inlet pipe is connected with condensate water import 3-1, rising pipe is connected with condensation-water drain 3-2, the condensate water closed cycle is played cooling effect to condenser pipe 3.Air intake opening 7-2 on the scrubber tube 7 is an air suction inlet.Take by weighing 0.5g plasterboard sample and place flat bottom flask 1, add magnesium perchlorate in the scrubber tube 7, add the 10mL formaldehyde absorbent in the absorption tube 5, the phosphoric acid solution that adds 20mL1.5mol/L in the straight type separating funnel 4, open the flow rate regulation piston 4-1 of separating funnel, drips of solution in the straight type separating funnel 4 is added in the flat bottom flask 1, opens air sampler 6 simultaneously, flow set is 0.3mL/min.Slowly heating flat bottom flask 1 boils to solution wherein is little, and heating 50min is continued in the boiling back, and in whole process, keeping the flow velocity of air sampler 6 is 0.3mL/min.After reaction finishes, adopt the content of sulphuric dioxide in the absorption liquid in the methylene blue spectrophotometry absorption tube 5.
