본 발명은 철도차량용 형광등 커버 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a fluorescent lamp cover for a railway vehicle.

일반적으로 지하철, 전철 및 완행열차 등과 같은 철도차량에는 내부를 밝게 하는 형광등이 설치되어 있으며, 이러한 형광등을 보호하고 조도를 조절하는 형광등 커버가 장착되어 있다.In general, a fluorescent lamp that brightens the interior is installed in railroad cars such as subways, trains, and trains, and a fluorescent lamp cover that protects the fluorescent lamp and adjusts illuminance is installed.

그러나 종래의 철도차량에서는 가벼운 중량과 가공의 용이성으로 인해 아크릴이나 폴리카보네이트와 같은 수지로 된 형광등 커버를 사용하였지만, 이들은 타기 쉬운 물질인 가연성 물질이기 때문에 화재시 매우 위험하며 유독가스의 원인이 되고 있다.However, the conventional railroad cars used fluorescent lamp covers made of resins such as acrylic and polycarbonate due to their light weight and ease of processing. However, these are highly flammable materials that are easily burnable and are a cause of toxic gas. .

또한, 강화유리를 이용하여 형광등 커버를 제조할 경우 종래의 강화유리로 만든 유리판은 4mm이상의 두께를 요구하고 있어 중량이 증가하고, 가공이 용이하지 않으며, 화재나 충격으로 인해 파괴될 경우 파편이 비산되어 인체에 상해를 입히는 등의 문제점이 있다.In addition, when manufacturing a fluorescent lamp cover using tempered glass, glass plates made of conventional tempered glass require a thickness of 4 mm or more, which increases weight, is not easy to process, and fragments scattered when destroyed by fire or impact. There is a problem such as causing injury to the human body.

본 발명은 전술한 문제점을 해결하기 위하여 안출된 것으로, 내충격성과 강도가 매우 높으면서도 두께가 얇고 중량이 가벼운 형광등 커버를 제조할 수 있는 철도차량용 형광등 커버 제조방법을 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a fluorescent vehicle cover manufacturing method for a railway vehicle that can manufacture a fluorescent cover with a thin thickness and light weight while having a very high impact resistance and strength.

상기에 있어서, 상기 (c)단계와 (d)단계 사이에, 상기 유리판을 원하는 크기로 절단하는 (g)단계;를 더 포함하는 것이 바람직하다.In the above, between (c) and (d) step, (g) cutting the glass plate to a desired size; preferably further comprises.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예에 따른 철도차량용 형광등 커버 제조방법을 순차적으로 도시한 순서도이고, 도 2는 도 1의 제조방법에 의해 제조된 형광등 커버를 도시한 단면도이다.1 is a flowchart sequentially illustrating a method for manufacturing a fluorescent lamp cover for a railway vehicle according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional view showing a fluorescent lamp cover manufactured by the manufacturing method of FIG.

도 1에 도시한 바와 같이, 본 실시예의 철도차량용 형광등 커버 제조방법은 다음과 같은 단계로 이루어진다.As shown in Figure 1, the manufacturing method of the fluorescent lamp cover for a railway vehicle of the present embodiment consists of the following steps.

먼저, 유리판을 준비한다. (a단계) 이 단계에서는 유리판을 반입하여 유리판 의 결점을 제거하고, 유리판에 부착되어 있는 이물질을 깨끗하게 클렌징하는 공정들이 포함된다. 유리판의 두께는 1.5mm 내지 2.5mm가 적당하다.First, a glass plate is prepared. (Step a) This step involves removing the defects of the glass plate by importing the glass plate, and cleansing the foreign matter adhered to the glass plate. As for the thickness of a glass plate, 1.5 mm-2.5 mm are suitable.

이후, 상기 유리판을 630℃ 내지 670℃로 가열하여 원하는 형상으로 굽힌다. (b단계) 이 단계에서, 상기 유리판을 630℃ 내지 670℃의 온도로 70분 내지 110분 동안 가열하는 것이 바람직하다. 유리는 특성상 온도에 매우 민감하므로 너무 높은 온도로 오랫동안 가열하게 되면 점성이 높아 굽힘 가공하기에 용이하지 않으며, 너무 낮은 온도로 가열하게 되면 가공이 용이하지 않으므로 630℃ 내지 670℃의 온도로 70분 내지 110분 동안 가열하는 것이 바람직하다.Thereafter, the glass plate is heated to 630 ° C. to 670 ° C. and bent into a desired shape. (Step b) In this step, it is preferable to heat the glass plate at a temperature of 630 ℃ to 670 ℃ for 70 minutes to 110 minutes. Glass is very sensitive to temperature, so it is not easy to bend when it is heated to a high temperature for a long time and it is not easy to bend when heated to too low temperature, so it is 70 minutes to a temperature of 630 ℃ to 670 ℃. It is preferred to heat for 110 minutes.

이후, 상기 유리판의 온도가 580℃ 내지 600℃의 변이점이 될 때 상기 변이점의 온도에서 10분 내지 30분간 유지하는 것이 바람직하다.(f단계) 이는 유리의 잔류응력을 제거하기 위함이다.Then, when the temperature of the glass plate is a transition point of 580 ° C to 600 ° C it is preferable to maintain for 10 to 30 minutes at the temperature of the transition point (step f) This is to remove the residual stress of the glass.

이후, 상기 유리판을 공기 중에서 5시간 내지 7시간 정도로 서서히 냉각시킨다. (c단계) Thereafter, the glass plate is slowly cooled in air for about 5 hours to 7 hours. (step c)

이후, 상기 유리판을 원하는 크기로 절단하는 것이 바람직하다. (g단계) 이렇게 상기 (c)단계와 (d)단계 사이에 유리판을 절단하는 것은 (c)단계 전까지는 절단된 유리판을 각각 가열하고 냉각시키는 것보다 절단되지 않은 유리판을 한번에 가열하고 냉각시키는 것이 용이하며, (d)단계에서는 절단된 상태의 유리판을 가열로 내에 도입하는 것이 용이하기 때문이다.After that, it is preferable to cut the glass plate to a desired size. (Step g) Cutting the glass plate between the steps (c) and (d) is to heat and cool the uncut glass plate at once rather than heating and cooling the cut glass plates until step (c). This is because it is easy to introduce the glass plate in the cut state into the heating furnace in step (d).

이후, 상기 유리판을 가열로에 도입하여 590℃ 내지 670℃로 가열하여 열처리한다. (d단계) 이 단계에서 유리판을 590℃ 내지 670℃의 온도로 2분 내지 3분 동안 가열하는 것이 바람직하다. 열처리 단계에서 유리판을 가열하는 온도와 시간에 따라 유리판의 강도가 달라지므로 이 단계는 매우 중요한 단계이다.Thereafter, the glass plate is introduced into a heating furnace and heated to 590 ° C. to 670 ° C. to heat treatment. (Step d) In this step, it is preferable to heat the glass plate at a temperature of 590 ° C to 670 ° C for 2 to 3 minutes. This step is very important because the strength of the glass plate varies depending on the temperature and time of heating the glass plate in the heat treatment step.

다음은 유리판의 열처리 가열온도에 따른 잔류응력을 측정하는 방법이다.The following is a method of measuring the residual stress according to the heat treatment heating temperature of the glass plate.

5. 계산방법5. Calculation method

측정치는 이하의 식에서 계산된다.The measured value is calculated by the following equation.

* 눈금의 읽기 α(도)* Reading of scale (degrees)

* 기계의 계수 C(nm/mm) - 이 실험장치의 경우 3.274* Coefficient C of the machine (nm / mm)-3.274 for this test apparatus

* 광탄성 상수 ε ((nm/cm)/(kg/㎠) - 유리의 경우 2.5 내지 2.63* Photoelastic constant ε ((nm / cm) / (kg / ㎠)-2.5 to 2.63 for glass

* 판두께 t(mm)* Plate thickness t (mm)

* 응력 F(kg/㎠)* Stress F (kg / ㎠)

Figure 112006088760290-pat00003
Figure 112006088760290-pat00003

계산 편의상 다음과 같은 식을 상기 식에 대입한다.For convenience of calculation, the following equation is substituted into the above equation.

Figure 112006088760290-pat00004
Figure 112006088760290-pat00004

대입하면 응력 F는 다음과 같은 식으로 요약된다.Substituting, the stress F can be summarized as follows.

Figure 112006088760290-pat00005
Figure 112006088760290-pat00005

형광등 커버인 경우 응력 F는 95㎏/㎠ 이상이 되어야 한다.In the case of fluorescent lamp covers, the stress F shall be not less than 95㎏ / ㎠.

다음의 표 1는 상기 잔류응력 측정방법에서 이동량 α값에 따른 응력 F값을 나타낸 표이다. 유리판의 두께 t는 2.1mm로 하였다.The following Table 1 is a table showing the stress F value according to the shift amount α value in the residual stress measurement method. The thickness t of the glass plate was 2.1 mm.

Figure 112006088760290-pat00006
Figure 112006088760290-pat00006

상기의 표 1에서 나타나 있듯이, 이동량 α가 15일 때 응력 F가 93.6㎏/㎠이므로 α는 15 이상이어야 한다.As shown in Table 1, when the moving amount α is 15, the stress F is 93.6 kg / cm 2, and α must be 15 or more.

다음의 표 2은 가열온도 625℃, 가열시간 2분 30초로 하여 열처리한 유리판의 이동량 α값을 측정한 결과이다.The following Table 2 shows the results of measuring the shift amount α value of the glass plate heat-treated at a heating temperature of 625 ° C. and a heating time of 2 minutes 30 seconds.

Figure 112006088760290-pat00007
Figure 112006088760290-pat00007

상기의 표 2에서와 같이, 가열온도를 625℃로 하여 열처리할 경우 α값이 15 이상이 나오지 않음을 알 수 있다.As shown in Table 2 above, it can be seen that when the heat treatment is performed at a heating temperature of 625 ° C., an α value of 15 or more does not come out.

다음의 표 3는 가열온도 680℃, 가열시간 2분 10초로 하여 열처리한 유리판의 이동량 α값을 측정한 결과이다.The following Table 3 shows the results of measuring the shift amount α value of the glass plate subjected to heat treatment at a heating temperature of 680 ° C. and a heating time of 2 minutes 10 seconds.

Figure 112006088760290-pat00008
Figure 112006088760290-pat00008

상기의 표 3에서와 같이, 가열온도를 680℃로 하여 열처리할 경우 α값이 15 이상 나오지만, 변형이 너무 잘 일어난다는 문제점이 발생하였다.As shown in Table 3 above, when the heat treatment is performed at a heating temperature of 680 ° C., the α value is 15 or more, but a deformation occurs too well.

다음의 표 4 및 표 5은 가열온도 6℃, 가열시간 2분 10초로 하여 열처리한 유리판의 이동량 α값을 측정한 결과이다.Tables 4 and 5 below show the results of measuring the amount of shift α of the glass plate heat-treated at a heating temperature of 6 ° C. and a heating time of 2 minutes 10 seconds.

Figure 112006088760290-pat00009
Figure 112006088760290-pat00009

Figure 112006088760290-pat00010
Figure 112006088760290-pat00010

상기의 표 4 및 표 5에서와 같이, 가열온도를 670℃로 하여 열처리할 경우 α값이 15 이상 되어 매우 높은 강도를 가지는 유리판을 얻을 수 있었다.As shown in Table 4 and Table 5, when the heat treatment at a heating temperature of 670 ℃ to α value was 15 or more to obtain a glass plate having a very high strength.

한편, 상기 (d)단계 이후, 상기 유리판을 0.2MPa 내지 0.6MPa의 압축공기로 급냉한다. (e단계) On the other hand, after the step (d), the glass plate is quenched with compressed air of 0.2MPa to 0.6MPa. (step e)

상기 (e)단계 이후 상기 냉각된 유리판의 일면에 파편비산방지 및 조도조절을 위한 피막층을 형성하는 (h)단계를 더 포함하는 것이 바람직하다. 피막층의 두께는 0.08mm 내외가 적당하며, 0.2mm 이상으로 되면 너무 두꺼워 발열량이 커진다는 단점이 있다.After the step (e), it is preferable to further include the step (h) of forming a coating layer for preventing fragments scattering and roughness control on one surface of the cooled glass plate. The thickness of the coating layer is appropriate around 0.08mm, there is a disadvantage that the amount of heat generated is too thick when the thickness is 0.2mm or more.

피막층의 일실시예로서, 피막층은 폴리에틸렌 테레프탈레이트(Polyethylene Terephthalate ; PET) 필름일 수 있다.As an example of the coating layer, the coating layer may be a polyethylene terephthalate (PET) film.

피막층의 다른 실시예로서, 피막층은 페인트를 도포하여 형성한 층일 수 있다.As another embodiment of the coating layer, the coating layer may be a layer formed by applying paint.

상기와 같은 방법으로 제조된 철도차량용 형광등 커버를 도 2에 도시하였다. 도 2의 도면부호 100은 유리판이며, 200은 피막층이다.The fluorescent lamp cover for the railway vehicle manufactured by the above method is shown in FIG. 2. Reference numeral 100 in Fig. 2 is a glass plate, and 200 is a coating layer.

이와 같이 제조된 철도차량용 형광등 커버를 사단법인 일본철도차량기계 기술협회에 의뢰하여, 철도차량용 재료 연소시험을 실시하였다.The railroad fluorescent lamp cover thus manufactured was commissioned by the Japan Railroad Vehicle Technology Association, a division company, and carried out a combustion test for railroad vehicle materials.

표 6은 콘카로리 시험성적서이고, 표 7은 차재연소 시험성적서이다.Table 6 shows the test results for cone calories, and Table 7 shows the test results for in-vehicle combustion.
