액체화물 탱크용 단열박스 및 그 제조방법{INSULATION BOX FOR LIQUID CARGO TANK AND THE MANUFACTURING METHOD OF IT}INSULATION BOX FOR LIQUID CARGO TANK AND THE MANUFACTURING METHOD OF IT

본 발명은 액체화물 탱크용 단열박스 및 그 제조방법에 관한 것으로, 더욱 상세하게는 극저온 액체화물의 열손실을 최소화하면서도 경량화 구현이 가능함은 물론, 구조적 강도를 향상시킬 수 있도록 하는 액체화물 탱크용 단열박스 및 그 제조방법에 관한 것이다.The present invention relates to an insulating box for a liquid cargo tank and a method of manufacturing the same, and more particularly, to minimize the heat loss of the cryogenic liquid cargo and to realize a light weight as well as to insulate the liquid cargo tank. It relates to a box and a manufacturing method thereof.

NO96 멤브레인형 LNG선의 초저온 액체화물 탱크는 통상 내부 선체(inner hull)의 내측에 복수의 인바 멤브레인(invar membrane)이 배치되고, 내부 선체와 인바 멤브레인 각각의 사이에는 단열재가 내장된 단열박스가 배치된다.In the cryogenic liquid cargo tank of the NO96 membrane type LNG carrier, a plurality of invar membranes are usually disposed inside the inner hull, and an insulation box having a built-in insulation is disposed between the inner hull and the invar membrane. .

특히, NO계열의 단열박스는 액체화물 탱크로부터의 하중을 견디기 위하여 비교적 두꺼운 판재 형상인 플라이우드(plywood)를 수직 부재로 사용하여 좌굴 및 압축에 견디도록 한다.In particular, the NO series insulation box uses plywood, which is a relatively thick plate, as a vertical member to withstand the load from the liquid cargo tank to withstand buckling and compression.

그러나, 이러한 수직 부재를 통하여 손실되는 열량은 단열박스로부터 발생되는 열손실의 40 내지 50%를 차지하므로, 수직 부재는 단열 성능의 저하에 큰 요인으로 작용하게 되었다.However, since the amount of heat lost through the vertical member accounts for 40 to 50% of the heat loss generated from the thermal insulation box, the vertical member acts as a significant factor in the deterioration of the thermal insulation performance.

따라서, 큰 부피를 차지하지 않으면서도 단열 성능의 유지가 가능하고 구조적 강도를 향상시킬 수 있도록 하는 구조적 개선이 절실한 것이다.Therefore, structural improvements that can maintain the insulation performance and improve the structural strength without taking up a large volume is urgently needed.

상기와 같은 다양한 실시예에 따른 액체화물 탱크용 단열박스의 제조 방법에 대하여 도 8 내지 도 11을 참고로 살펴본다.A method of manufacturing an insulating box for a liquid cargo tank according to various embodiments as described above will be described with reference to FIGS. 8 to 11.

우선, 본 발명은 도시된 바와 같이 하부 금형(700)과 상부 금형(800) 사이에서 압착시켜 제조된 파형 격벽(300)을 상, 하부 판재(100, 200) 사이에 등간격으로 배치하고 단열재(400)를 충진하는 실시예를 적용하는 것임을 파악할 수 있다.First, as shown in the present invention, the corrugated partition wall 300 manufactured by pressing between the lower mold 700 and the upper mold 800 is disposed at equal intervals between the upper and lower plate members 100 and 200, and the heat insulating material ( It can be seen that the embodiment of the present invention is filled with 400).

우선, 작업자는 도 8과 같이 제1 단계(S1)에서 상면에 산(m)과 골(v)의 패턴이 반복적으로 형성된 하부 금형(700) 상에 필름 형상의 심재(f)를 배치하는 작업을 실시한다.First, the worker arranges the film-shaped core material f on the lower mold 700 in which the pattern of the peak m and the valley v is repeatedly formed on the upper surface in the first step S1 as shown in FIG. 8. Is carried out.

여기서, 심재(f)는 필름 형상의 유리 섬유 또는 탄소 섬유임은 전술한 바와 같다.Here, the core material f is as described above that the film-like glass fiber or carbon fiber.

이후, 작업자는 도 9와 같이 제2 단계(S2)에서 심재(f) 상에 극저온용 합성수지(r)를 도포하는 작업을 실시한다.Thereafter, the worker performs the operation of applying the cryogenic synthetic resin (r) on the core material (f) in the second step (S2) as shown in FIG.

여기서, 극저온용 합성수지(r)는 에폭시, 폴리에스터, 페놀 수지 중 어느 하나 또는 적어도 하나 이상의 조합인 것이 바람직하다.Here, the cryogenic synthetic resin (r) is preferably any one or a combination of at least one of epoxy, polyester, phenol resin.

계속하여, 작업자는 도 10과 같이 제3 단계(S3)에서 하부 금형(700)의 패턴에 대응되는 형상의 패턴이 하면에 형성된 상부 금형(800)이 심재(f)를 압착하여 산(m)과 골(v)이 반복적으로 형성된 파형 격벽(300)을 제조하게 된다.Subsequently, in the third step S3, the worker presses the core material f by the upper mold 800 formed on the lower surface of the pattern corresponding to the pattern of the lower mold 700, as shown in FIG. 10. And to form a corrugated partition 300 is formed repeatedly valleys (v).

여기서, 심재(f)가 유리 섬유일 경우 극저온용 합성수지(r)를 심재(f)의 일면에만 도포하여도 유리 섬유의 구조적 특성상 극저온용 합성수지(r)가 스며들어 심재(f)의 양면에 도포되는 상태로 파형 격벽(300)이 성형될 수 있다.Here, when the core material (f) is glass fiber, even if the cryogenic synthetic resin (r) is applied only to one surface of the core material (f), the cryogenic synthetic resin (r) is infiltrated due to the structural properties of the glass fiber and applied to both sides of the core material (f). The corrugated partition wall 300 may be molded in such a state.

이때, 심재(f)가 탄소 섬유일 경우 제1 단계(S1)를 실시하기 전에 극저온용 합성수지(r)를 하부 금형(700)에 도포하고, 심재(f)를 배치하는 제1 단계(S1)를 실시한 후, 심재(f)의 상면에 극저온용 합성수지(r)를 도포하는 제2 단계(S2)를 실시함으로써 제3 단계(S3)에 의한 파형 격벽(300), 즉 심재(f)의 양면에 극저온용 합성수지(r)가 도포된 파형 격벽(300)을 얻을 수 있을 것이다.In this case, when the core material f is carbon fiber, the cryogenic synthetic resin r is applied to the lower mold 700 and the core material f is disposed before the first step S1 is performed. After carrying out, the second step (S2) of applying the cryogenic synthetic resin (r) to the upper surface of the core material (f) by performing the third step (S3) of the corrugated partition wall 300, that is, both sides of the core material (f) The corrugated partition wall 300 to which the cryogenic synthetic resin r is coated may be obtained.

다음으로, 작업자는 도 11과 같이 제4 단계(S4)에서 상, 하부 판재(100, 200) 사이에 복수의 파형 격벽(300)이 직교되게 등간격으로 고정시키고 파형 격벽(300)과 이웃한 파형 격벽(300) 사이에 단열재(400)를 충진하는 작업을 수행함으로써 액체화물 탱크용 단열박스의 제조가 완료되는 것이다.Next, in the fourth step S4, the worker fixes the plurality of corrugated partition walls 300 at equal intervals orthogonally between the upper and lower plate members 100 and 200 and neighbors the corrugated partition walls 300 as shown in FIG. 11. The manufacturing of the insulating box for the liquid cargo tank is completed by performing the operation of filling the insulating material 400 between the corrugated partition walls 300.

이때, 제4 단계(S4)에서 작업자는 도 7의 실시예와 같이 파형 격벽(300)과 단열재(400)를 섬유 필터(600)로 감싸는 과정을 더 실시할 수도 있음은 물론이다.In this case, in the fourth step S4, the worker may further perform a process of wrapping the corrugated partition 300 and the heat insulating material 400 with the fiber filter 600 as in the embodiment of FIG. 7.

이상과 같이 본 발명은 극저온 액체화물의 열손실을 최소화하면서도 경량화 구현이 가능함은 물론, 구조적 강도를 향상시킬 수 있도록 하는 액체화물 탱크용 단열박스 및 그 제조방법을 제공하는 것을 기본적인 기술적 사상으로 하고 있음을 알 수 있다.As described above, the present invention is to provide a heat insulating box for a liquid cargo tank and a method of manufacturing the same to minimize the heat loss of the cryogenic liquid cargo and to realize a light weight as well as to improve structural strength. It can be seen.

그리고, 본 발명의 기본적인 기술적 사상의 범주 내에서 당해 업계 통상의 지식을 가진 자에게 있어서는 다른 많은 변형 및 응용 또한 가능함은 물론일 것이다.It will be apparent to those skilled in the art that many other modifications and applications are possible within the scope of the basic technical idea of the present invention.
