월에 국내 중후판 가격이 대폭 하락했다.월 일까지 주요도시의 일반탄소판가격센터는 이미 으로 내려가 월말에 비해 톤당 원 하락했다.이달 초， 거시적인 나쁜 소식과 최근 기본면이 좋지 않은 영향으로 시장심리상태가 비관적으로 전환되였고 일부 거래원들은 저가로 출하했다.시장재고가 상승하고 재고압력이 높으며 재고부족현상이 소실되고 시장거래분위기가 랭담하며 수요표현이 지속적으로 하락하고 현물가격이 압력을 받아 하락하고있다.
The market opened today. Although the performance of Zitong Pai futures was modest， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature the market was bleak.
우 르 티 람Four in one formula and process conditions Preparation of solution Take formula as an example: mix the calculated amount of water for zinc oxide into a paste， then add zinc nitrate and tartaric acid slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved， dilute it with water to / of the total volume， add sodium alkosulfonate and OP emulsion， and stir to make it completely dissolved. Then add chromium dihydrogen phosphate dissolved in dilute phosphoric acid， and add titanium sulfate. After all materials are added， dilute them to the total volume， stir them to make the solution even， cool them to room temperature，우 르 티 람알루미늄 청동판， put a large amount of iron filings in the solution， and soak them for - days to make them contain enough ferrous ions. When the content of ferrous ion reaches above g/L， adjust the free acidity and total acidity of the solution to the specified value， and then the solution can be used at elevated temperature. When the ferrous ion reaches the above value， the phosphating speed is fast， the solution is stable， and the phosphating film is fine and dense. During operation， the degreasing technology of degreased copper pipe. How to make degreased copper pipe? The process flow of degreased copper tube? What are the characteristics of degreased copper tubes? Use of degreased copper tube? There are too many questions. Lets solve them at once. Everyone knows the copper tube. Nitrate reacts easily. The heater should be installed on the two walls of the tank， not on the bottom of the tank， to prevent local overheating. Stainless steel pipe or iron pipe should be used for heater， and lead pipe or copper pipe should not be used to avoid contamination of solution by impurities. What is degreased copper pipipe? "The advantages of degreased copper pipes comprehensive treatment of grease， rust removal， phosphating and passivation are described. This comprehensive treatment process can simplify the process， reduce the work area， save equipment costs， shorten working hours， in actual production， due to the amount of oil contamination， light and heavy rust， the consumption rate of each component in the solution is different， so attention should be paid to adjustment and control to maintain its due role. What is the degreasing copper tube? "I have roughly known the degreasing methods of degreasing copper tubes: solvent degreasing， alkali degreasing， ultrasonic degreasing， high pressure hot water degreasing， electrolytic degreasing，우 르 티 람주석 도금 적동 막대， etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe， collect it together into a container， volatilize， collect and reuse the volatile solvent， and separate the pollutants from the circulation system. This method was used in the early stage， which has problems such as low cleaning efficiency， difficult maintenance， and environmental pollution. In recent years， many kinds of surfactants have been developed. The lipophilic group of surfactants can help to dissolve oil in water to realize degreasing. Alkali degreasing: Alkali degreasing is a complex chemical physical process. In addition to saponification reaction， there are sometimes emulsion reaction and adsorption reaction. Typical saponification reaction formula is as follows: RCOOH+NaOHRCOONa+HO At present， industrial degreasers are composite reagents， and the solution temperature is ℃. Ultrasonic degreasing: ultrasonic degreasing is to degrease the upper and lower surfaces of red copper pipes by using ultrasonic to generate high-speed vibration， whichtly used for monomer and irregular shaped components. High pressure hot water degreasing: without degreasing agent， and spray it directly to the surface of red copper pipe for cleaning under the pressure of about bar. Electrolytic degreasing: electrolytic degreasing， using the red copper tube as the cathode to generate H， which will scour the oil stain on the surface of the red copper tube; The O generated by the anode is in atomic state and has strong oxidation capacity， which can improve the degreasing effect. Therefore the problem that alkali spraying and brushing cannot fully contact the micro concave part of the surface is solved. Generally， the cleaning effect of alkali degreaser spraying or high-pressure hot water degreasing plus brushing can meet the requirements of most users. If there are special requirements multiple methods can be used together. According to practical experience， the degreasing effect of various degreasing methods (one side of the copper tube) is as follows: alkali degreaser spray plus brushing: mg/m alkali degreaser brushing plus electrolytic degreasing: mg/m ultrasonic wave: mg/m high-pressure hot water degreasing: 이 파 카 라When stacking， it shall be stacked reasonably and placed first. Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong. The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
현재의 전체 가격차를 감안할 때， 오늘 현지 동봉 가격은 계속 높은 수준으로 상승하고 있지만， 화동 지역 이외의 지역은 뚜렷한 후속 추세가 나타나지 않고 있으며， 현지 가격은 여전히 동북과 화중 지역과의 가격차의 우세를 가지고 있다.생산 제한의 영향으로 현지의 후속 상품량이 비교적 적기 때문에， 현지의 재고 압력은 더욱 낮아질 것이며， 동봉 가격의 지탱은 여전히 강하다.그러나 현재 국내 부동산 통제는 여전히 강화되고 있다.시장 & # ;미래의 수요에 대한 시장의 예상이 약화되고 있습니다.오늘 심양 동봉의 시장 가격이 안정되어 출하량이 좋지 않다.

To sum up， 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.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.

The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Liaoning，우 르 티 람청동관， Shandong and other regions has increased. In addition， with the gradual release of downstream demand， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
