또한, 1,2-디클로로프로판(1,2-Dichloropropane)은 세척용재로 많이 사용되는데, 지방족 염소계 탄화수소 중에서 디클로로프로판은 대체로 오존파괴성이 거의 없으며, 저독성이고 세정력도 우수한 것으로 평가되고 있으며, 그 중에서도 1,2-디클로로프로판이 가장 우수한 것으로 평가되고 있다. 화학식은 CH3CCl2NO2 ; C3H7Cl2 로서, 본 발명에서는 각각의 혼합물이 서로 잘 섞일 수 있도록 용매의 역활을 수행한다.

이와 같이 구성된 휴대용 용접가스 조성물은 다음의 순차적인 공정을 통해 용접용기에 주입된다. The portable welding gas composition thus constructed is injected into the welding vessel through the following sequential process.
먼저, 액상의 14~30 중량% 아세톤과 1~10 중량% 펜탄의 혼합물을 용접용기의 내측에 주입하는 제1공정이 진행된다. First, a first process of injecting a mixture of liquid 14-30 wt% acetone and 1-10 wt% pentane into the welding vessel is performed.
상기 아세톤과 펜탄은 촉매 및 냉각제어를 위해 사용되는 것이므로, 연료 가스 성분과의 충분한 혼합을 위해 용접용기의 내측에 먼저 주입되는 것이 바람직하다. Since acetone and pentane are used for catalyst and cooling control, it is preferable to first inject the inside of the welding vessel for sufficient mixing with the fuel gas components.
이어서, 상기 용접용기를 밀폐하기 위해 크램핑(clamping)하고 상측에 밸브를 결합시키는 제2공정이 진행된다. Subsequently, a second process of clamping to seal the welding vessel and coupling the valve to the upper side is performed.
이때, 상기 밸브는 종래의 휴대용 부탄가스 용기와 동일한 구조로서, 중앙부를 내측으로 밀어넣으면 내부의 용접가스가 외측으로 방출되고, 일정 압력 이상으로 가압하여 내부로 다른 가스를 유입할 수 있게 된다. In this case, the valve has the same structure as a conventional portable butane gas container, and when the center portion is pushed inward, the welding gas is discharged to the outside, and the valve is pressurized to a predetermined pressure or more to allow other gas to flow therein.
상기 크램핑은 종래의 휴대용 가스 장치에서 주입된 가스의 유출을 방지하기 위해 별도의 자동화 설비를 통해 이루어지는 공지의 기술이므로, 이하 추가 설명은 생략한다. Since the clamping is a known technique made through a separate automation facility to prevent the outflow of the gas injected from the conventional portable gas device, further description will be omitted below.
이어서, 상기 밸브를 통해 일정한 가압을 하면서 액상의 45~60 중량% 프로판과 15~30 중량% 부탄의 혼합물을 주입하는 제3공정이 진행된다. Subsequently, a third process of injecting a mixture of 45 to 60 wt% propane and 15 to 30 wt% butane in a liquid phase is performed while applying constant pressure through the valve.
또한, 제3공정이 완료된 후, 상기 밸브를 통해 액상의 0.1~0.9 중량% 1,2-디클로로프로판, 0.1~0.5 중량% 메틸 카보네이트의 혼합물을 추가적으로 주입한다. In addition, after the third process is completed, a mixture of 0.1 to 0.9 wt% 1,2-dichloropropane, 0.1 to 0.5 wt% methyl carbonate in the liquid phase is additionally injected through the valve.
이로써 용접을 할 때 가열온도가 약1,500℃까지 상승하여 화력이 증대됨으로써 다양한 재질의 금속을 신속하게 용접할 수 있다.Thus, when welding, the heating temperature rises to about 1,500 ° C., thereby increasing the thermal power, so that metals of various materials can be quickly welded.
한편, 본 발명에 의한 용접 가스는 용기 내부에서 액상으로 존재하며, 외부로 배출되면서 공기압에 의해 가스로 변환되는데, 액상의 용접 가스가 이동시의 흔들림 또는 외부 충격에 반응하는 것을 방지하기 위해 용기에는 위 제1공정 이전 단계에서 스폰지 등의 완충재를 삽입하여 제조할 수도 있다. On the other hand, the welding gas according to the present invention is present in the liquid phase inside the container, is converted to the gas by the air pressure while being discharged to the outside, in order to prevent the liquid welding gas from reacting to the shaking or external impact during movement, It may be prepared by inserting a cushioning material such as a sponge in the step before the first process.
상기와 같은 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.The present invention as described above is not limited to the above-described specific embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various changes without departing from the gist of the present invention as claimed in the claims. will be.
