Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， circulates in the copper pipe heating pipe， heats the floor， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply， the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance，바 투 라 자주석 도금 동봉，바 투 라 자공심 알루미늄 관， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.

배치할 때는 다른 성분에 따라 따로 보관해야 하며 함께 혼합해서는 안 된다.구리 표면에는 전해질이 있을 수 있기 때문에 반응할 수 있으며， 특히 고무 등 다른 재료와 반응할 수 있어 큰 영향을 미칠 수 있다.
사라 미라This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend the price was stable to support the market， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.

비용 이 합리적이다.The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
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.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.

Four 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， slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved， then add zinc nitrate and tartaric acid， 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， 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， the phosphating speed is fast， the solution is stable， and the phosphating film is fine and dense. During operation， attention shall be paid to controlling the temperature. If the temperature is higher than ℃， 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， shorten working hours save equipment costs， improve labor productivity and reduce costs. This method can only be used in the occasions where the requirements for coating quality are not high.However， 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， etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe， 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， 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， heat the deionized water to ℃， 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: 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. 동판， 동봉과 동관의 다섯 가지 주요 응용 분야 중 네 가지: 동은 건축업에서 각종 파이프， 파이프와 장식 장치로 사용된다.
