Because of the characteristics of copper itself， it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， the problem will be smaller， but if it is placed for a long time， the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.
구리 재료의 저장 방법에 대해 말하자면， 우리는 우리가 구입한 구리 제품을 잘 보관하고， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
아 비 니 온Disadvantages: The pipe structure is loose， and it is not resistant to high pressure. It is only suitable for the production of small air conditioning copper pipes.

몬 트 리 올Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes，아 비 니 온구리 가방 알루미늄 실봉， the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance， but also very convenient to operate. There are three production methods for copper tube， so what are the three production methods for copper tube?
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and most of the downstream prices are asked and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the same below) yuan， yuan for Jin Zhengyang yuan yuan for Ruigang Lianlian， yuan for Baoda yuan， yuan for Meixin yuan， and yuan for Taizong yuan.

At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
Reasons for copper pipe corrosion: Air pollution.

The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material， and then the material is purified to produce copper tube materials.
Disadvantages: low output， which is the development direction of copper tube industry in the future.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
업무 설명먼저 구리 파이프를 가열하고 용접한 다음 이음매를 가열하여 가열된 부분이 진홍색으로 변할 때까지 가열합니다. 이때 충전 금속이 파이프와 접촉할 때 충전 금속은 용해되어야 합니다.
Water with low PH value causes corrosion.
상술한 바를 종합하면， 현재 현물 시장 가격이 상인들이 예상한 겨울 창고 저장 가격보다 훨씬 높은 등 요소의 영향으로철광석 가격이 상승함에 따라 철광석 가격지수는 한때 달러 아래로 떨어져 수입 광석의 출하 열기를 떨어뜨렸다.이밖에 환경보호검사가 더욱 엄격해져 일부 국내광산의 공급이 큰 영향을 받았다.현재 국내 광산의 가동률은 이전 최고치보다 % 포인트 낮아 앞으로 더 떨어질 것으로 보인다.

Five of the five major application fields of copper plate， copper bar and copper tube: copper is used in medicine. In the s， Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s， and successfully developed the corresponding "Cancer Suppressing "， which is successful in the near future.
