평탄 하 다.장점: 투자 원가가 낮고 생산 원가가 낮으며 생산량이 높고 가격이 낮다.
오늘 개장합니다.비록 지동파 선물의 성과가 평범하지만， 전체 시장은 이미 멈추었다.그 후 시장 심리 상태는 큰 변화가 없었다켄드.가격은 안정적이지만 일부 규격은 협상을 기다려야 하며 협상범위는 ~원 좌우이다.시장의 전반적인 리듬은 안정적이고 냉담하다.겨울 중기에 동북지역의 전체 시장은 전통적인 비수기에 접어들어 전체 시장의 마무리가 무기력하다.모든 회사가 상품을 판매하고 있다.재고 정리로 인해 선양의 재고 수준은 매우 낮으며 모든 건설 현장은 폐쇄되었습니다.저온으로 인한 운송 압력 외에 시장은 참담하다.
부 르 고 스일 중후반， 비록 좋은 소식이 있지만， 예를 들면 선물 가격 상승과 무강 생산 제한 정책이 증가한다;한 지역에서는 재고 수준이 매우 높기 때문에 무역상들이 가격을 인상할 의사가 없으며， 그들 중 대다수는 이미 출하되어 현물 가격이 상승할 동력이 부족하다.시장 재고가 대폭 증가하다.당시 한단의 시장 재고는 명절 후에 비교적 높은 수준에 이르렀다.장기간 부진한 수요표현은 시장의 공급이 수요를 초과하고 재고가 지속적으로 상승하여 시장의 심리상태가 공허해졌다.
Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
The excellent performance of copper pipe The copper pipe has the characteristics of and， which makes it a suitable choice for modern contractors to install water pipes， the price of domestic medium and heavy plates fell sharply. As of August ， the price center of ordinary carbon boards in leading cities had dropped to ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals the market mentality turned to pessimism， and some traders shipped at low prices. The market inventory rose， the inventory pressure was high， the stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
Avoid discoloration of coil surface due to pollution， flash point， acid value and distillation range and the third-party test report of elements harmful to copper tubes. In the rewinding process， strengthen the cleaning of the copper tube surface to reduce the residue of lubricating oil on the copper tube surface.

휘황찬란 하 게 주조 하 다.When placing， they should be stored separately according to the different components， and should not be mixed together. The copper surface may have electrolytes so it will react， especially with other materials such as rubber， which has a large impact.
In view of the current overall price difference， 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.
At the opening this morning， 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.

질 이 좋다To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore，평탄 하 다.316L 스테인리스 라운드 스틸， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
표준화 생산.
The material of the water separator is the same，평탄 하 다.구리 알루미늄 복합 배출， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.

At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
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)，평탄 하 다.주석 도금 동봉， 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.
