Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model corrosion device.
Description of reference numerals: 1, worktable; 2, well heater; 3, temperature controller; 4, rustless steel container; 5, plastic containers; 6, air-suction cover; 7, thermometer; 8, support.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, the Simple corrosion device of a kind of macroscopical microscopic examination of the present utility model, be placed on worktable 1, comprise well heater 2, temperature controller 3, rustless steel container 4 and plastic containers 5, well heater 2 is electrically connected with temperature controller 3, temperature controller 3 is connected with power supply, can the intensification of control heater 2 and switch by temperature controller 3; Rustless steel container 4 is placed on well heater 2, plastic containers 5 are placed in rustless steel container 4, the outer wall of plastic containers 5 does not directly contact with the inwall of rustless steel container 4, water is filled with between them, well heater 2 conducts heat to the water in rustless steel container 4 fast, and then conduct to plastic containers 5, the aqueous hydrochloric acid solution that solution compolision is 1:1 (volumetric ratio) is filled in plastic containers 5, in the specific implementation, plastic containers 5 and rustless steel container 4 can adopt the plastic tub and Stainless steel basin that are easy on the market purchase respectively.
Be provided with the thermometer 7 for monitoring aqueous hydrochloric acid solution temperature in plastic containers 5, the top of thermometer 7 is fixed by support 8, and lower end is arranged in plastic containers 5, and support 8 is fixed on worktable 1; Plastic containers 5 overthe openings is provided with downward opening air-suction cover 6, and air-suction cover 6 adopts sheet metal to make, and lower end is arranged on worktable 1 by pillar, and the upper end of air-suction cover 6 is communicated with blower fan, for being discharged by the part aqueous hydrochloric acid solution of evaporation; Well heater 2 comprises refractory brick and is arranged on the resistance wire on refractory brick, and resistance wire is electrically connected with temperature controller 3.
Below the course of work of above-mentioned corrosion device is described in further detail, to represent its principle of work:
First be that the aqueous hydrochloric acid solution of 1:1 (volumetric ratio) is poured in plastic containers 5 by appropriate solution compolision, need ensure that the lower end of thermometer 7 is flooded by aqueous hydrochloric acid solution, then by open temp controller 3, resistance wire is heated up, heat is successively by rustless steel container 4, water, plastic containers 5 reach aqueous hydrochloric acid solution, staff observes the temperature of aqueous hydrochloric acid solution by thermometer, when temperature reaches 75 DEG C, test button is put into the aqueous hydrochloric acid solution of plastic containers 5, now aqueous hydrochloric acid solution temperature can reduce, when temperature reaches 75 DEG C again, resistance wire is made to stop heating up by closing temperature controller 3, now aqueous hydrochloric acid solution meeting slow cooling, when the temperature of aqueous hydrochloric acid solution temperature is down to about 70 DEG C, resistance wire is made again to be warming up to 75 DEG C by open temp controller 3, and then close, circulation said process is until sample corrosion terminates.Concrete, general cooling aqueous hydrochloric acid solution temperature is down to 70 DEG C of needs seven or eight minutes from 75 DEG C, if calculated with etching time 15min, only needs two circulations to complete.
Corrosion device of the present utility model, structure is simple, and simple operation, cost is low, has good applicability.
