The circumference of the first flow measurement hole 111a and the depth of the first flow measurement hole 111a may be formed differently from each other. In this case, the circumference of the first flow measuring hole 111a may be twice the depth of the first flow measuring hole 111a.

Specifically, looking at the design specifications, the circumference of the first flow measurement hole (111a) may be 10mm. In addition, the depth of the first flow measurement hole 111a may be 5 mm.

Meanwhile, the second flowability measurement hole 111b may be formed similarly to the first flowability measurement hole 111a. In this case, the circumference of the second flow measuring hole 111b may be formed to be equal to the depth of the second flow measuring hole 111b.

Specifically, when the circumference of the second flowability measurement hole 111b is 10mm, the depth of the second flowability measurement hole 111b may also be 10mm.

Therefore, the first flowability measuring hole 111a and the second flowability measuring hole 111b are designed to measure flowability as a 5mm or 10mm hole having a diameter of 10mm, and in particular, the second flowability measuring hole 111b having a depth of 10mm. In the case of relatively small flowable samples,) is designed so that specimens of the same length and thickness are completely exposed to the space, and the first flowability measuring hole 111a having a depth of 5 mm is relatively flowable so that In this case, half the thickness of the specimen is designed to flow through the exposure to the space can be selected and used as needed.

In addition, the second self-smoothness measurement hole 112b may have a circumference of 20 mm and a depth of 10 mm.

In this case, the first self-smoothness measuring hole 112a and the second self-smoothness measuring hole 112b may be designed to measure self-smoothness, in particular, the second self-smoothness measuring hole 112b having a depth of 10 mm. Silver can be designed to measure the properties of a sample having a relatively low self-smoothness, and the first self-smoothness measuring hole 112a of 5 mm depth is designed to measure the properties of a sample having a high self-smoothness. It can be selected and used as needed.

However, the first self-smoothness measuring hole 112a and the second self-smoothness measuring hole 112b are not limited to the above, and various values such as 10 mm and 20 mm in diameter and depth may be mixed depending on the type of protective coating agent.

In this case, the simulation measurement hole 113 may be formed in multiple stages. In addition, the simulation measurement hole 113 may be formed in the shape of a long hole.

Specifically, the design specifications of the simulation measurement hole 113 may be formed of 3mm wide, 80mm long, 3mm deep. In this case, the simulation measurement hole 113 may be formed to have various values according to the design specifications in addition to the above.

On the other hand, the simulation measuring hole 113 of 80mm in length 3mm in width 3mm is designed to demonstrate the test of the actual application, and most users try to load as many specimens as possible in the same place in order to improve productivity, the protection After applying the coating agent is stored upright, by simulating through the simulation measurement hole 113 can be verified at the same time the applicability. At this time, the length of about 80mm is the self-smoothness and flowability of the protective coating agent containing no lead wire is a length sufficient for the simulation.

Therefore, the plate 110 may provide a space capable of accurately and effectively utilizing the flowability and self-smoothness of the protective coating agent.

FIG. 6 is an operating state diagram showing a first operation of the protective coating agent characteristic measuring apparatus 100 shown in FIG. 1.

Referring to FIG. 6, the self-smoothness may be measured through the protective coating agent property measuring apparatus 100. Hereinafter, the first to third steps will be described as self-smoothness measurement steps 1 through 3 to measure self-smoothness for convenience of explanation.

1. First step in self-smoothness measurement;

The protective coating agent property measuring apparatus 100 may be mounted on a flat surface or a laboratory desk. In this case, the plate 110 may be horizontally disposed on the ground or the laboratory desk by the support plate 160.

When the first self-smooth measurement pressing portion 141 and the second self-smooth measurement pressing portion 142 are raised upwards, two kinds of protective coating agents C may be drawn out to the outer surface of the plate 110. (See Figure 4)

At this time, when the two types of protective coating agent (C) is drawn out to the outer surface of the plate 110, the experimenter can measure the spread of the two types of protective coating agent (C). Specifically, the experimenter can measure the spreading degree of the protective coating agent (C) through the length measuring means 170 formed on the plate 110 or an external device.

On the other hand, when the experiment as described above, the experimental conditions can be observed by spreading for 2 hours under 50 ± 10% relative humidity in the normal temperature and normal pressure state. At this time, by measuring the spreading degree of the two types of protective coating agent (C) it can be confirmed the characteristics of the two types of protective coating agent (C).

Looking at the above results, the two types of protective coating agents (GY100614-1, GY100712-1), as shown in the <Table 1> as there is only about 20% difference that the difference in viscosity characteristics is not clearly distinguished As a viscosity, the characteristics of the protective coating agent (C) cannot be completely classified and standardized.

However, as a result of measuring the self-smoothness () of the protective coating agent (C) through the protective coating agent characteristic measurement apparatus 100, as shown in Table 1, a difference of up to 5 times or more occurs, and by using the standardized protective coating agent (C Clearness and objectivity can be secured in the measurement of

Therefore, the protective coating agent characteristic measuring apparatus 100 objectively and reasonably measures the self-smoothness (spreadability, self-leveling), which is an important characteristic of the protective coating agent (C), to clarify the specification of the protective coating agent (C), and the protective coating agent (C). ), It is possible to suggest mutually clear, objective and reasonable ways to develop and apply protective coating (C).

In addition, the protective coating agent characteristic measuring device 100 is clear and objective enough to be compared with the appearance that the spread of the protective coating agent (C) is formed even when tested with a silicone coating of a similar composition of self-smoothness of the protective coating agent (C). Results can be derived.

7 is an operating state diagram showing a second operation of the protective coating agent characteristic measuring apparatus 100 shown in FIG.

Referring to FIG. 8, flowability may be measured through the protective coating agent property measuring apparatus 100. Hereinafter, the first to third steps will be described as flow measurement first to flowability measurement third steps for convenience of description.

1. The first step in flow measurement;

When measuring the flowability of the protective coating agent (C), the plate 110 may be disposed parallel to the ground or the laboratory desk. In this case, the protective coating agent C may be inserted into the first flowability measuring hole 111a or the second flowability measuring hole 111b. In particular, the protective coating agent (C) may include two kinds similar to those described in FIGS. 7 and 8.

Since the method of removing the exposed protective coating agent (C) is similar to that described with reference to FIGS. 7 and 8, a detailed description thereof will be omitted.

2. second step of flow measurement;

When the above process is completed, inside the first flow rate measuring hole 111a and the second flow rate measuring hole 111b through the first flow rate measurement pressing unit 131 and the second flow rate measurement pressing unit 132. The protective coating agent (C) can be taken out to the outside.

In this case, when the protective coating agent (C) is drawn out of the first flowability measuring hole 111a and the second flowability measuring hole 111b, the plate 110 may be disposed perpendicularly to the ground or a laboratory desk.

In particular, when the plate 110 is disposed vertically, the support plate 160 may be in contact with the ground or the laboratory desk to maintain the plate 110 vertically.

3. third step of flow measurement;

When the above process is completed, the flowability of the protective coating agent (C) drawn out of the first flowability measuring hole 111a or the second flowability measuring hole 111b after a predetermined time while maintaining a predetermined temperature and a predetermined humidity. The degree can be measured.

In this case, as described above, the predetermined temperature may be a predetermined temperature at room temperature, the predetermined humidity may be 50 ± 10% relative humidity at a normal pressure, and the predetermined time may be 2 hours.

On the other hand, the results of the experiment as described above are shown in Table 2 below.

division GY100614-1 GY100712-1 Viscosity, cPs, Brookfield LVT # 4/6 rpm 48,000 40,500 Flowability, mm (diameter 10 X 10 mm holes) 30 61 80 X 3 X 3 Flow, mm 0 10

Looking at the above results, the two types of protective coating agents (GY100614-1, GY100712-1) as shown in the <Table 2> there is only a difference of about 20% that the difference in viscosity characteristics are not clearly distinguished As a viscosity, the characteristics of the protective coating agent (C) cannot be completely distinguished and standardized.

However, as a result of measuring the flowability of the protective coating agent (C) through the protective coating agent characteristic measurement apparatus 100, as shown in Table 2, a difference of up to two or more times occurs, and by using this to standardize the characteristics of the protective coating agent (C) Clearness and objectivity can be secured in the measurement of.

In addition, the protective coating agent characteristic measuring apparatus 100 can check the behavior of the protective coating agent (C) applied to the actual product through the simulation measuring hole 113. At this time, the protective coating agent (C) can be inserted into the simulation measuring hole 113, and a part of the protective coating agent (C) can be taken out through the simulation pressing part 150 to check the behavior.

Looking at the results obtained through the above process, as shown in Table 2, GY100614-1 of the protective coating agent (C) has a flowability of 30mm, but when applied to the actual product effectively protective coating agent (C) without flowability It can be seen that it is applicable while playing the role of. On the other hand, GY100712-1 of the protective coating agent (C) can be confirmed that the flow is 60mm and not applicable because the flow occurs when the actual product is applied.

Therefore, the protective coating agent characteristic measuring device 100 by objectively and reasonably measuring the flowability, which is an important characteristic of the protective coating agent (C), to clarify the specifications of the protective coating agent (C) and to facilitate the application of the protective coating agent (C) Provide clear, objective, and rational means for the development and application of (C).

In addition, the protective coating agent characteristic measuring device 100 is clear and objective enough to be comparable in the form of the protective coating (C) flow even when tested with a silicone coating agent having a similar composition of flowability of the protective coating agent (C). Can be derived.

In particular, the protective coating agent characteristic measuring device 100 is a test device intended to be applied and applied to the industry by objectively and reasonably evaluating the required flowability as a characteristic of the protective coating agent (C). By not lowering, it is intended to solve various problems caused by the application coatings not playing a role appropriate to the original required properties, and for the supplier and the user to evaluate the properties clearly with the same measuring method.
