Description

백동유기칼의 제조방법{Manufacturing method of bronze organic knife}{Manufacturing method of bronze organic knife}

본 발명은 백동유기칼의 제조방법에 관한 것으로, 더욱 상세하게는 구리와 니켈을 혼합하여 만들어지는 백동에 주석, 마그네숨, 아연을 미량 혼합하여 백색을 띠게 하여 미감을 높이고 또한 칼날의 경도를 적당히 유지하여 절삭력과 내마모성을 유지하여 칼의 기능을 갖추도록 한 것으로, 백동의 살균(殺菌), 항균(抗菌), 무독(無毒)의 기능을 할 수 있는 무공해 금속으로 형성하여 위생적인 음식문화를 즐길 수 있도록 한 백동유기칼의 제조방법에 관한 것이다.More particularly, the present invention relates to a method for manufacturing a white copper organic knife, and more particularly, to a method for manufacturing a white copper organic knife, which comprises mixing a tin, magnesium and zinc in a white brick made by mixing copper and nickel, It is made of pollution-free metal that can function as disinfection, antibacterial, and non-toxic of Baekdong to maintain the cutting power and abrasion resistance and to enjoy the hygienic food culture. The present invention relates to a method for manufacturing a white organic knife.

일반적으로, 백동유기는 구리에 니켈을 15~25% 내외의 중량비로 혼합하여 된 합금으로써 인체에 무해한 특성으로 인하여 오래전부터 식자재인 놋그릇이나 수저를 생산하여 각종 식생활에 적용하였으며 또한 가공이 용이하여 생활도구로 널리 사용되어 왔다.Generally, Baekdong Organic is a mixture of copper and nickel at a weight ratio of about 15 ~ 25%. It is harmless to the human body and has long been used for producing brassware and cutlery. Has been widely used as a tool.

동과 니켈의 합금으로 Ni 15~25%, 나머지는 Cu의 일반조성을 갖는 백색의 강인동 합금이다. 유사한 것으로 니켈과 아연을 포함한 양은(양백이라고도 한다)이 있다. 소성, 가공성이 좋고 열간 가공 등에 적합하며 해수에 대한 내식성도 좋다. 비교적 고온에서도 잘 견디며 열교환기, 화학공업 등의 내식재료로써 사용된다.An alloy of copper and nickel, which is 15 to 25% Ni, and the remainder is a white, strong alloy with a general composition of Cu. There is a similar amount of nickel and zinc (also called nickel). Good firing, good workability, suitable for hot working, corrosion resistance to seawater is also good. It is resistant to relatively high temperatures and is used as a food material for heat exchangers and chemical industries.

백동유기로 제조된 그릇은 살균효과와 더불어 독성물질에 반응하면서 음식 맛을 살려주는 기능은 물론 상추나 채소를 담아 보관하였을 때 일반 냉장보관보다 오랫동안 싱싱함을 유지하는 기능성을 갖추고 있음이 밝혀졌으며,In addition to its sterilizing effect, Baekdong Organic Bowl has a function to maintain freshness for a long time longer than general refrigerated storage when stored with lettuce or vegetables, as well as a function to restore food taste in response to toxic substances.

종래의 선출원된 특허등록출원된 것을 살펴보면,As for a patent application filed in the prior art,

10-2015-0095229가 있었으나 이를 구체적으로 살펴보면 구리와 주석을 넣어 청동유기를 만들고 여러 개의 청동유기판을 만들어 이를 겹쳐 압연과 단조를 하여 더욱 단단한 청동유기제품을 만들었다.10-2015-0095229. However, if we look at this in detail, we made copper and tin to make bronze organic and made several bronze organic plates, rolled and forged to make harder bronze organic products.

이와 같은 방법은 칼의 경도를 높일 수는 있으나 여러 개의 청동유기판을 하나의 몸체로 만들기 위해 압연공정, 단조공정을 거쳐야 하는 번거로운 작업공정이 필요하여 제작원가를 높이는 문제점이 있었다.Such a method can increase the hardness of the knife, but it requires a complicated work process requiring a rolling process and a forging process in order to make a plurality of bronze organic plates into a single body, which raises the production cost.

또한 청동유기로 제작되는 칼은 많이 제작되어 있지만 백동유기로 제작되는 칼은 개발되지 않고 있는 실정이다.In addition, although many knives made of bronze organic are produced, knives made of white brass are not developed.

본 발명은 백동을 이용하여 주방에서 사용하는 칼을 제작하는 것으로, 백동의 원료에 주석 마그네슘 아연을 혼합하여 칼날의 적당한 경도를 유지할 수 있는 한 것으로,The present invention is to produce a knife for use in a kitchen using a whisk, which can maintain the proper hardness of the blade by mixing tin magnesium zinc with the raw material of the whisk.

백동의 아름다운 미감을 살리고 또한 칼날의 경도를 유지하며 백동의 살균(殺菌), 항균(抗菌), 무독(無毒)의 기능을 할 수 있도록 하여 위생적인 주방생활을 할 수 있도록 제공한 것이다.It provides a sanitary kitchen life by allowing the beautiful beauty of Baekdong to be maintained, maintaining the hardness of the blade, and sterilizing Baekdong, antibacterial and nontoxic functions.

이러한 목적을 달성하기 위한 본 발명은, 구리와 니켈을 합금한 백동에 주석과 마그네슘, 아연을 혼합되게 칼의 경도를 높이고 백색의 아름다움이 표출되도록 하는 모재를 얻고 압연공정과 단조공정을 하여 칼의 형태로 만들며 열처리공정과 연마공정 불림공정을 거쳐 칼의 제조를 완성한 것으로,In order to achieve the above object, the present invention provides a base material in which a hardness of a knife is increased and a beauty of white is expressed by mixing tin, magnesium and zinc in a white cast iron alloyed with copper and nickel, and a rolling process and a forging process are performed. And finished the manufacture of the knife after the heat treatment process and the polishing process called the process,

칼날의 경도를 높여 칼날의 마모를 줄일 수 있으며 칼을 장시간 사용하여도 칼날이 쉽게 마모되지 않도록 하며 백동의 미감을 느낄 수 있도록 발명한 것이다.By increasing the hardness of the blade, it is possible to reduce the wear of the blade, and the blade can be easily worn even when the knife is used for a long time, and the blade can feel the beauty of the blade.

이와 같은 백동을 이용하여 주방에서 사용하는 백동유기칼을 제작하는 것으로, 백동의 원료에 주석 마그네슘 아연을 혼합하여 칼날의 적당한 경도를 유지하고 칼날이 전체적으로 백색을 띄게 하여 미감을 높일 수 있도록 한 것으로,By using such a pearl to make a pearl organic knife for use in a kitchen, it is possible to maintain the proper hardness of the blade by mixing tin magnesium zinc with the raw material of pearl,

백동의 미감을 살리고 또한 칼날의 경도를 유지하며 백동의 살균(殺菌), 항균(抗菌), 무독(無毒)의 기능을 할 수 있도록 하므로 다양한 음식을 자를 때 주로 사용되는 주방용 칼을 매우 위생적으로 사용할 수 있도록 하는 효과가 있다.It is very hygienic to use kitchen knife which is mainly used when cutting various food, because it makes it possible to utilize Baekdong's aesthetics and maintain the hardness of blade and to sterilize, antibacterial and non-toxic of Baekdong There is an effect to be able to.
