Because of the characteristics of copper itself stability and performance， it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， 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.
산 드 바구리 재료의 저장 방법에 대해 말하자면， 우리는 우리가 구입한 구리 제품을 잘 보관하고， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way， not only is the copper surface serious it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment， so this effect is very good.
According to * * new data， in September ， Chinas imported iron ore * * * broke through the million ton mark， reaching million tons， a record high; From January to September， Chinas iron ore import increased by % to million tons， and the annual import volume is expected to exceed billion tons. However， judging from the shipment of imported ores after the National Day， due to the rapid declinecline in iron ore prices， the iron ore price index once fell below $， which reduced the enthusiasm for the shipment of imported ores. In addition， environmental protection inspection has become stricter， and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak， which is likely to decline further in the future.
Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper)， deoxidized copper plate (TUP， TUMn)， and special copper plate (arsenic copper， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
Copper pipe corrosion caused by soft water.

However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
In terms of steel billets: at :， some steel billets in Changli were reduced by ， the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore， it can be seen that at this stage，에 무 라15CRMO 합금 플레이트， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton，에 무 라2205 스테인리스 강판， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.

Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight， good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?
에 무 라The market price of Zhengzhou copper bars is basically stable， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory，에 무 라구리 알루미늄 복합 배출， and there is no large replenishment plan. The demand is sluggish， and the market price of Zhengzhou copper bar is expected to be stable and declining.
