The test specimens are usually 75x150 mm in size and installed to be inclined at an angle of 20 ° to the specimen holder. When salt water is sprayed on the inclined surface, corrosion occurs on the surface.

At this time, the time at which corrosion (such as white rust, red rust, etc.) occurs varies depending on the composition and type of the specimen, the material coated on the surface, and the thickness. Generally, when corrosion test is performed in a brine test apparatus, it is evaluated that corrosion resistance is better as the time during which no corrosion occurs is longer. However, in order to accurately measure the corrosion, it is necessary to observe the corrosion behavior of the specimen from time to time or take the specimen out of the apparatus and check the photographing.

1, when the door 3 is opened to check the state of the specimen S in the conventional brine testing apparatus 1, the brine vapor V in the chamber 2 is discharged to the outside So that the temperature and humidity inside the chamber 2 are lowered. As the phenomenon is repeated, the corrosive atmosphere inside the chamber 2 becomes weak, so that accurate evaluation can not be made.

In the conventional brine testing apparatus 1, since the angle at which the specimen S is fixed is fixed, it is not possible to change the conditions of the corrosion test. Therefore, depending on the degree of spraying of the brine

Hereinafter, a salt water testing apparatus according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2 and 3, the present invention is a brine testing apparatus for performing corrosion test by spraying brine on a specimen, which comprises a door 12 on one side and a spray nozzle 14 for spraying brine on the inside thereof A specimen base 100 installed so as to face the injection nozzle 14 and horizontally movable to the inside and outside of the chamber 10 through an opened door 12, A specimen fixing shaft 121 which is rotatably provided horizontally in the horizontal direction and inserted and fixed at one end of the specimen S and adjusts the angle between the specimen S and the injection nozzle 14 while rotating, And a driving unit 150 installed on the specimen base 100 and rotating the specimen fixing shaft 121 in contact with the specimen fixing shaft 121.

The conventional brine testing apparatus has a structure in which the upper part thereof is opened to replace the specimen S or to check the state of the specimen S, and there is a problem that a large opening area and a long opening time lead to a large amount of saline vapor.

In the present invention, a door 12 is provided on the side surface of the chamber 10, and the specimen base 100 is slid through the door to move to the inside and the outside of the chamber 10. The specimen base 100 is slid and moved to the inside and the outside of the chamber 10 so that the door 12 is opened only when the specimen base 100 is moved and the specimen base 100 is moved outside or inside the chamber 10 The door 12 can be closed to minimize the leakage of the brine vapor.

More specifically, the chamber 10 includes a main body 11, which is a kind of tank in which a sample S is placed and in which salt water is sprayed, a brine tank W installed in an inner lower portion of the main body 11, A pump 16 installed in the tank W and a spray pipe 15 for supplying the brine to the upper inside surface of the main body 11 by receiving the brine water through the pump 16, May be provided on the inner upper surface of the main body.

That is, the main body 11 of the chamber 10 of the present invention is opened and closed only by the door 12, unlike the conventional case where the top surface is opened. Further, by disposing the spray nozzle 14 on which the salt water is sprayed on the upper surface of the main body 11, there is also an effect that the salt water can be uniformly sprayed into the main body 11. [

The chamber 10 further includes a door cylinder 13 connected to the door 12 for opening and closing the door 12, a base moving shaft 220 provided below the specimen base 100, A base moving motor 210 connected to one end of the moving shaft 220 to rotate the base moving shaft 220 and a base moving motor 210 installed between the base moving shaft 220 and the specimen base 100, And a rail 17 on which the wheel 112 travels.

At this time, the base extension part 113 extending from one end of the specimen base 100 passes through the base movement axis 220 and moves according to the rotation of the base movement axis 220 to move the specimen base 100 forward and backward have.

When the base moving shaft 220 is rotated by the rotation of the base moving motor 210, the base extension 100 (FIG. 3) 113 are moved forward and backward, and the specimen base 100 connected thereto is moved forward and backward and moved to the inside and the outside of the chamber 10.

As shown in FIG. 6, the chamber 10 may be composed of one main body 11, but may be a plurality of main bodies 11 in which inner spaces are separated from each other.

The door 12, the salt water tank W, the pump 16, the injection pipe 15, and the injection nozzle 14 are provided for each of the main bodies 11, . Corrosion tests of various conditions can be simultaneously performed through the plurality of main bodies 11.

4 and 5, the specimen fixing shaft 121 is rotatably mounted on the specimen base 100. The specimen fixing shaft 121 is rotatably mounted on the driving unit 150, So that the inserted specimen S can be rotated. By changing the angle by rotating the specimen S in this manner, the conditions of the corrosion test can be simply changed. The specimen fixing shaft 121 may be directly pivotally mounted on the specimen base 100. The specimen fixing shaft 121 may be rotatably mounted on the specimen base 100 by inserting the shaft head 122 protruding from both ends of the specimen fixing shaft 121 into the specimen base 100 have.

The specimen-securing shaft 121 is formed in a semicircular shape. For convenience, the specimen-securing shaft 121 is divided into a curved surface portion and a planar portion. That is, a portion having a circular arc cross section in a column having a semicircular cross section is referred to as a curved surface portion, and a portion having a linear cross section is referred to as a planar portion. A specimen (S) is inserted into the flat portion. For this purpose, a specimen groove larger than the thickness of the specimen (S) is formed on the flat portion.

A fixing protrusion 123 is provided on a side wall of the test piece groove, and the fixing protrusion 123 is connected to the specimen fixing shaft 121 via a fixing spring. At this time, the fixing spring is installed in the specimen groove in the direction of the inner surface of the specimen fixing shaft 121, and the fixing protrusion 123 presses the specimen S inserted into the specimen groove by the elastic force of the fixing spring.

When the specimen (S) is detached, the fixing spring is loosened and the specimen (S) is advanced again. Therefore, the specimen S can be stably supported by the elastic force of the fixing spring, and the specimen S having various thicknesses can be inserted into the specimen groove. At this time, it is preferable that the end of the fixing protrusion is subjected to a rounding treatment so that it can naturally retreat when the test piece S is inserted.

In addition, a water drop port 124 is formed at the bottom of the sample groove, so that the salt water can be discharged without being accumulated.

The curved surface portion is in contact with the driving portion 150, and a gear tooth is formed on the surface of the curved surface portion to be engaged with the driving portion 150. Accordingly, when the driving unit 150 moves, the specimen fixing shaft 121 rotates.

The driving unit 150 includes a rack gear 131 that directly engages with the gear teeth described above and a moving table 131 that is provided below the rack gear 131 and that supports the rack gear 131 and is movable in the horizontal direction A support shaft 133 for connecting the rack 133 and the moving base 133 to provide a resilient force and a gear shaft 142 installed through the moving base 133, And an angle regulating motor 141 which is installed in the gear shaft 142 and is coupled to one end of the gear shaft 142 to rotate the gear shaft 142.

When the angle adjusting motor 141 rotates, the gear shaft 142 connected thereto is rotated, and the moving base 133 is moved back and forth according to the rotation of the gear shaft 142. The gear shaft 142 may be a kind of screw shaft that moves the movable table 133 back and forth while moving along a thread formed inside the movable table 133 by rotation.

The rack gear 131 is formed obliquely so as to gradually increase in height from one end to the other end so that one end of the rack gear 131 and the other end of the specimen fixing shaft 121 The other end of the rack gear 131 and the curved surface of the specimen fixing shaft 121 are in contact with each other when the curved surface portion abuts and the movable table 133 is positioned at the advancing position, And the other end of the rack gear 131 and the curved surface of the specimen-securing shaft 121 are compressed when the curved surface of the specimen-securing shaft 121 abuts.

That is, the distance between the rack gear 131 and the moving base 133 is variable, the support spring 132 can be compressed while being compressed, and the support spring 132 can be released while being relaxed. This is because the gear teeth formed at the hypotenuse of the rack gear 131 always come into close contact with the gear teeth formed on the specimen-fixing shaft 121. That is, when the movable base 133 is retreated and the lower end of the rack gear 131 and the curved surface of the specimen fixing shaft 121 are in contact with each other, the support spring 132 is released to lift the rack gear 131, The support spring 132 is gradually compressed as the contact point moves from one end of the rack gear 131 to the other end while the rack gear 131 advances and the rack gear 131 descends, The supporting spring 132 is compressed while the other end of the rack gear 131 contacts with the curved surface of the specimen fixing shaft 121 so that the rack gear 131 and the moving base 133 come close to each other.

With such a structure, the rack gear 131 can always be brought into close contact with the specimen-fixing shaft 121, and the reliability of rotating the specimen-fixing shaft 121 can be improved.
