クライHow 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， that is stir it with a glass rod to prepare ammonia solution， 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， chalk or talcum powder can also be mixed into 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.
First of all we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， while the humidity should be normal. The room should be kept ventilated.
ノニトランニクSafe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals， has good toughness and high ductility， and has excellent anti vibration， anti impact and anti frost expansion properties.
赤銅在庫は持続的な低下傾向に終止符を打つ可能性がある.鉄鋼企業の生産制限力の増大と需要圧力の増大に伴い，鉄鉱石港湾在庫の継続的な低下は終了する可能性がある.また，**の 新統計によると，製鉄所が鉄鉱石を輸入できる日数は日で，国慶節前より日減少し，過去 高となった.製鉄所によると，現在の鉄鉱石在庫は生産要求をほぼ満たしている.将来の減産と制限を考慮して， 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，クライ6082アルミニウムストリップ， 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， 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，クライ銅被覆アルミ線棒， air conditioners and other places where bending pipes are needed. When we use copper， we need not consider the preservation problem unless we buy a small amount at home. For example， Now lets ask our staff to introduce the storage method of copper for you.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high， and the willingness to further replenish the inventory is not strong. In terms of supply， the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection， the quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.

antages: low production cost and high production efficiency.
So far as the storage method of copper materials is concerned， we should properly keep the copper products we buy， extend the service life of copper and ensure its performance to avoid unnecessary losses.

市場価格The production method of soft copper tube is basically the same as that of hard copper tube， 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， the copper tubes will become soft， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
The water quality at the place where the copper pipe is required to be installed shall be studied，e the sleeve on the pipe to evenly apply the flux on the joint， and confirm that the pipe is inserted into the bottom of the socket， then wipe off the excess flux， and the joint is assembled and can be heated.
