Abstract
The utility model provides an acid rain simulated corrosion unit, belonging to the technical field of test equipment. The acid rain simulated corrosion unit comprises a box body, a humidity adjustment component, a temperature controller, a sulfur dioxide introduction pipe and a fan, wherein the humidity adjustment component, temperature controller and fan are arranged in the box body; a box cover is arranged above the box body; and the side wall of the box body is provided with the sulfur dioxide introduction pipe. The acid rain simulated corrosion unit can effectively simulate accelerated corrosion of acid rain on concrete, control the humidity and temperature, and well simulate the external environmental conditions. The acid rain simulated corrosion unit stimulates accelerated corrosion of acid rain on concrete at a certain temperature under a certain relative humidity, reproduces the damage level of the concrete within a certain time range, performs a corrosion test on the concrete, and can well simulate the corrosion mechanism of the acid rain. The acid rain simulated corrosion unit has the advantages of simple structure and low cost, and is convenient to operate and easy to implement.
Description
Technical field
The utility model relates to a kind of corrosion device, is specifically related to a kind of test unit with sulphuric dioxide Simulated Acid Rain corrosion concrete, belongs to the testing equipment technical field.
Background technology
Very surprising by the caused loss of concrete erosion, along with improving constantly that people require various buildingss (structures) service life, make the research of concrete durability become countries in the world concrete research personnel's study hotspot and emphasis.Cause the factor of concrete durability deficiency a lot, the environment acidifying is one of them.Correctly select the environmental protection measure of buildings, the guarantee buildings exempts from damage, in use safe and reliable.Thereby it is to guarantee the requisite important step of its permanance that concrete is carried out to manual simulation's environmental test.Manual simulation's environmental test is the scientific epitomization of actual environment impact, have typification, standardization, easy to use, be convenient to relatively wait characteristics.The variation of environmental baseline and the importance of environmental test have also proposed stricter requirement to environmental test equipment.
The utility model content
The purpose of this utility model is to provide a kind of corrosion case of Simulated Acid Rain corrosion, enters to corrode in case to reach the device of Simulated Acid Rain corrosion by introducing sulphuric dioxide.
The utility model solves the technical scheme that its technical matters adopts: a kind of Modeling of Acid Rain corrosion device, comprise casing, damping parts, temperature controller, sulphuric dioxide inlet tube and fan, establish damping parts, temperature controller and fan in described casing, case lid is offered in the casing top, and wall box is established the sulphuric dioxide inlet tube.
The part of described sulphuric dioxide inlet tube in casing is that around tank distributes and establishes several through holes.
Described wall box is also established U-shaped pipe, for measuring the pressure of box house.
Adopt watertight construction between described case lid and casing, overflow without salt fog.
Described casing, damping parts, temperature controller and fan are made by resistant material.
Described casing is of a size of 120cm * 60cm * 75cm.
Described fan is connected with power supply source.
Need are carried out to the concrete of analog detection and put into casing from case lid, introduce sulphuric dioxide by the sulphuric dioxide inlet tube is corroded it in casing to concrete, fan is evenly distributed the sulfur dioxide gas imported in casing, detect the pressure in casing by U-shaped pipe, simulate the environmental baseline of certain temperature and relative humidity by damping parts and temperature controller, concrete is carried out to accelerated corrosion, reappear the destructiveness that concrete suffers in the certain hour scope.
The beneficial effect that the utility model possesses is:
After employing the utility model, the effective Simulated Acid Rain of energy, carry out accelerated corrosion to concrete; Can regulating and controlling humidity and temperature, simulate well external environment condition.Utilize sulfur dioxide gas, at the environment Imitating acid rain of certain temperature and relative humidity, concrete is carried out to accelerated corrosion, reappear the destructiveness that concrete suffers in the certain hour scope.Box house in specified volume imports a certain amount of sulfur dioxide gas, makes, in situation that concentration, temperature, relative humidity are constant, concrete is carried out to corrosion test, well the corrosion mechanism of Simulated Acid Rain.The utility model is simple in structure, easy to operate, cheap, easy to implement.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-damping parts, 2-temperature controller, 3-U type pipe, 4-sulphuric dioxide inlet tube, 5-fan, 6-casing, 7-case lid.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, the Modeling of Acid Rain corrosion device comprises casing 6, damping parts 1, temperature controller 2, sulphuric dioxide inlet tube 4 and fan 5, establish damping parts 1, temperature controller 2 and fan 5 in described casing 6, case lid 7 is offered in casing 6 tops, and casing 6 sidewalls are established sulphuric dioxide inlet tube 4; The part of sulphuric dioxide inlet tube 4 in casing 6 is that around tank 6 distributes and establishes several through holes; Casing 6 sidewalls are also established U-shaped pipe 3, for measuring the pressure of box house; Adopt watertight construction between case lid 7 and casing 6, overflow without salt fog; Casing 6, damping parts 1, temperature controller 2 and fan 5 are made by resistant material; Casing 6 is of a size of 120cm * 60cm * 75cm; Fan 5 is connected with power supply source.
Need are carried out to the concrete of analog detection and put into casing 6 from case lid 7, introduce sulphuric dioxide by sulphuric dioxide inlet tube 4 is corroded it in casing 6 to concrete, fan 5 is evenly distributed the sulfur dioxide gas imported in casing 6, the pressure detected in casing 6 by U-shaped pipe 3, the environmental baseline of certain temperature and relative humidity by 2 simulations of damping parts 1 and temperature controller, concrete is carried out to accelerated corrosion, reappear the destructiveness that concrete suffers in the certain hour scope.
