잉 카 스 던 록How to make copper tubes shine copper is stable in dry air， but the surface of power copper tubes is easy to be corroded in humid air， generating a layer of green material， commonly known as "copper green"， and its main component is "basic copper carbonate". So， how to remove verdigris? We can remove the verdigris by mechanical friction but this is not only troublesome， but also will damage the surface of the bronze. Heres a good way to remove verdigris. Use a measuring cylinder to measure ml of concentrated ammonia water and put it into a beaker， then add ml of distilled water， stir it with a glass rod to prepare ammonia solution， that is， wipe copper water. Copper rubbing water can react with verdigris to form soluble blue copper ammonia complex， thus removing the verdigris. In order to improve the effect of removing verdigris from the copper polishing water， which can increase the mechanical friction， fully expose the deep layer of copper rust， ensure the complete reaction of verdigris and ammonia， and make the copper surface smooth and bright. Dip cotton in copper water and repeatedly scrub copper products with copper rust. Soon， the copper rust disappeared from the surface of the bronze ware， and the copper products showed a bright metallic luster again， while the cotton was dyed blue. When the verdigris on some copper products are not easy to remove， soak them in the copper scrubbing water for a while， and then scrub them with cotton dipped in the copper scrubbing water.
Disadvantages: low output， high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation， which is the development direction of copper tube industry in the future.
델 자 벤 스 크The 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， and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes， 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， 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.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， and the prices of spot market manufacturers eased slightly today. According to the feedback， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.

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.

품질 이 좋다연동관의 생산 방법은 경동관과 기본적으로 같다. 즉 경동관에 비해 퇴화 공정을 증가시켰다.동관의 퇴화는 그들이 고온로에서 하소하여 동관의 원소의 배열을 바꾼다는 것을 의미한다.그러나 불이 꺼지면 구리 파이프가 부드러워져 더 쉽게 구부러집니다.이런 방식으로 생산된 동관을 소프트 동관이라고 한다.
To prevent core problems of copper tubes the outlet tempmperature of copper tubes should be well controlled. The cooling capacity of the annealing furnace in the cooling stage should be improved by equipping a refrigeration unit for the annealing furnace， so as to ensure that the outlet temperature of copper tubes does not exceed ℃. By controlling the outlet temperature of copper tubes， the problems of the core of coil tubes and the inner wall of the purging inlet end can be solved.
