At the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.
To sum up， the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment， as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year， and it is hard to improve in the short and medium term. On the whole， the market price of Shenyang copper bars may be stable tomorrow.
카 파 리 카Soft water is easy to cause copper pipe corrosion.
The second of the five application fields of red copper plate T， red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels， distillation pots， brewing pots， etc.
하 이 드 라 바Among the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
The production method of soft copper tube is basically the same as that of hard copper tube， that is， the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However， after annealing，카 파 리 카T2 동판，카 파 리 카합금강， the copper tubes will become soft， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
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.

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， T， oxygen free copper plate (TU TU and high-purity， vacuum oxygen free copper)， and special copper plate (arsenic copper TUMn)， 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.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.
고객 이 제일이다.The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore， they are generally used in power plants， switches of electrical equipment， the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube， it can also be used as a hard tube， so the soft copper tube is used in more places， and can be used in a straight tube way， asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer，카 파 리 카네모난 알루미늄 관， it can be cut randomly according to the length， so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators， we need not consider the preservation problem unless we buy a small amount at home. For example， large manufacturers use copper units to buy a large number of copper pipes once， so there will be a problem. I believe some people do not know how to store unused copper materials， Now lets ask our staff to introduce the storage method of copper for you.
Reasons for copper pipe corrosion: Air pollution.
The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
