陰離子聚丙烯酰胺水解度越高越好嗎？其實這個問題太抽象了,陰離子聚丙烯酰胺不一定水解度越高就好；應該關于某類型的污水，陰離子挑選哪種水解度的適宜。 咱們先了解一下，陰離子聚丙烯酰胺 的制備與那些要素有聯系： 丙烯與丙烯酰胺單體合成聚丙烯酰胺的反應為自由基聚合反應，聚合速度、共聚物的組成、產品分子量及其分子量散布等是衡量該反應的重要目標，影響這些目    標的要素首要有反應的溫度、反應液的堿 度、引發系統、單體的比率及濃度等。 上面是比較學術型，如果看不懂沒聯系，咱們有簡單一點的說法。 點擊翻開原圖 陰離子聚丙烯酰胺的分子量是差異他們的一個目標，陰離子分子量大多都在800-2000萬之間。 跟著水解度的添加，羧基陰離子添加，分子鏈不斷伸展，然后有使絮凝作用逐漸增強的作用；一起，聚丙烯酰胺分子的負電性亦逐漸增強，又阻礙了其與負電性的泥沙雜質相吸附，并且在吸附架橋中起 首要作用的活性基團-酰胺基也不斷減少，然后跟著水解度的添加，又存在使絮凝作用逐漸變差的要素。 陰離子聚丙烯酰胺作為綜合成果：水解比過大，加堿費用較高，水解比過小，又會使反應不足，陰離子型聚丙烯酰胺的混凝或助凝作用較差。 所以陰離子聚丙烯酰胺不一定水解度越高越好，什么都會有個限度，適宜的才是zui優的河南安家凈環保是一家專業出產各種水處理藥劑，致力于綠色環？稍偕Y源的繼續使用，很多投入了科 研資金，首要產品有聚丙烯酰胺絮凝系列，聚合氯化鋁系列，聚合硫酸鐵系列，堿式氯化鋁等均受到全國客戶的一致好評，咱們將一如即往的出產出品質優質的產品來報答客戶對咱們一向的支持聚丙烯酰胺生產及市場現狀分析，可得以下幾點認識： The higher the degree of hydrolysis of anionic polyacrylamide, the better? In fact, this problem is too abstract. Anionic polyacrylamide does not necessarily have a higher degree of hydrolysis; it should be about a certain type of sewage, which degree of hydrolysis is suitable for anion selection. Let's first understand that the preparation of anionic polyacrylamide is related to those factors: the reaction between acrylic acid and acrylamide monomer to synthesize polyacrylamide is a radical polymerization reaction. The rate of polymerization, the composition of the copolymer, the molecular weight of the product and its molecular weight distribution are important objectives to measure the reaction and influence these objectives. The main factors are reaction temperature, alkalinity of reaction solution, initiation system, monomer ratio and concentration. The above is more academic. If you can't understand it, let's put it in a simpler way. The molecular weight of anionic polyacrylamide is one of the goals to differentiate them. Most of the anionic molecular weights are between 8 million and 20 million. With the addition of hydrolysis degree, carboxylic anion extends the molecular chain, and then enhances the flocculation effect gradually. Together, the negative electricity of polyacrylamide molecule increases gradually, which hinders its adsorption with negative sediment impurities, and the active group-amide, which plays an important role in bridging the adsorption process, also hinders its adsorption with negative sediment impurities. The flocculation is deteriorated gradually with the addition of hydrolysis degree. Anionic polyacrylamide as a comprehensive result: the hydrolysis ratio is too large, the cost of adding alkali is higher, the hydrolysis ratio is too small, and the reaction will be insufficient, the coagulation or coagulation of anionic polyacrylamide is poor. Therefore, anionic polyacrylamide is not necessarily hydrolyzed higher, the better, everything will have a limit, the appropriate is Zui excellent Henan Anjiajing Environmental Protection is a professional production of various water treatment agents, committed to the continued use of green and environmentally friendly renewable resources, a lot of investment in scientific research funds, the primary product is polyacrylamide flocs. Coagulation series, polyaluminium chloride series, polyferric sulfate series, alkaline aluminium chloride series and so on are all praised by the national customers. We will continue to produce high-quality products to repay customers for our support of the production and market analysis of polyacrylamide, we can get the following understandings: 1、我國已有10個5000t/a以上的PAM生產廠，其中有5個萬噸級PAM大廠。這典 廠家占全國年產量的56%，生產的集中度正在提高。PAM全行業的總銷售額為62億元。 2、PAM的主要用途是油田、水處理、造紙三大領域，而且仍然會有增大用量的余地。 大市場水處理已占整個PAM市場的1/4，并且將會比油田市場的增長速度更快；目前造紙市場比較集中，由四五家PAM廠所占有，其中某些品種有較強的專用性。陽離子型聚丙烯酰胺所占比例只有13%，從水處理市場今后發展來看，陽離子型聚丙烯酰胺的發展都將有更快的增速。 3、目前，PAM產品在我國的能源戰略、節水戰略中占有重要的地位，是不可缺少的產品，它在我國乃至全世界的能源危機以及下一個更為嚴重的水資源危機中將會扮演更為積極的角色。 4、由于一些油田淡水資源的缺乏及降低生產成本、環保等方面的要求，三次采油多采用污水配制聚合物，對耐溫抗鹽聚合物的需求越來越多，有面取代高分子聚丙烯酰胺的趨勢，而我國能夠生產抗鹽聚合物的企業只有三四家，總生產能力在6×104t左右，遠遠不能滿足三次采油的需求，因此，抗鹽聚丙烯酰胺具有廣闊的應用前景。 There are 10 PAM factories with a capacity of more than 5000t/a in China, of which there are 5 large PAM factories with a capacity of 10,000 tons. This manufacturer accounts for 56% of the country's annual output, and the concentration of production is increasing. The total sales volume of PAM industry is 6.2 billion yuan. 2. The main uses of PAM are oil field, water treatment and papermaking, and there is still room for increasing the amount of PAM. The second largest market, water treatment, has accounted for one fourth of the total PAM market and will grow faster than the oilfield market. At present, the paper-making market is relatively concentrated and occupied by four or five PAM factories, some of which have strong specificity. The proportion of cationic polyacrylamide is only 13%. From the future development of water treatment market, the development of cationic polyacrylamide will have a faster growth rate. 3. At present, PAM products occupy an important position in China's energy strategy and water-saving strategy, and are indispensable products. It will play a more active role in the energy crisis in China and the world as well as in the next more serious water resources crisis. 4. Because of the shortage of freshwater resources in some oilfields and the requirement of reducing production cost and environmental protection, sewage is mostly used to prepare polymers for tertiary oil recovery. There is an increasing demand for temperature-resistant and salt-resistant polymers, which tends to replace polymer polyacrylamide in an all-round way. However, only three or four enterprises in China can produce salt-resistant polymers. The total production capacity of salt-resistant polyacrylamide is about 6 *104t, which can not meet the demand of tertiary oil recovery. Therefore, salt-resistant polyacrylamide has broad application prospects. In addition, the demand for polyacrylamide products will increase considerably in recent years due to the attention paid by our government and relevant enterprises to sewage treatment. Most domestic enterprises plan to build polyacrylamide projects mainly for urban sewage treatment. According to experts'prediction, the annual demand of municipal wastewater treatment in Shanghai alone will reach 1 x104t. It can be expected that the application potential of polyacrylamide products in wastewater treatment will be tremendous. It can be seen that salt-resistant polyacrylamide products have broad application prospects in tertiary oil recovery and sewage treatment.     此外，由于近幾年來我國和有關企業對污水處理事業的重視，對聚丙烯酰胺產品的需求量將會有較大幅度的增加。國內大部分企業擬建聚丙烯酰胺項目主要是針對城市污水處理。預測，僅上海的城市污水處理年需量將達1×104t，可以預期聚丙烯酰胺產品在 污水處理方面應用的潛為巨大。 由此可見，抗鹽聚丙烯酰胺產品在三次采油和污水處理方面的應用前景十分廣闊，其他行業的應 5、本品可用于堿性電鍍錫的添加，但對鍍層及電鍍過程并無明顯影響，不是必要成分。乙酸鈉常用作緩沖劑，如用于酸性鍍鋅、堿性鍍錫和化學鍍鎳。 6、污水處理中的效果：為反硝化菌補充碳源，對反硝化污泥進行訓化，之后使用緩沖溶液將反硝化過程中pH值的上升幅度控制在0.5范圍內。反硝化菌可過量吸附CH3COONa,因此在以CH3COONa為外加碳源進行反硝化時,可將出水COD值也能維持在較低水平。 當時一切城市及縣城的污水處理想要達到排放一級規范就需要添加乙酸鈉做碳源。投放規范：當乙酸鈉投加量為15mg/L時,體系各參數出口濃度均可達鄉鎮污水處理廠污染物排放規范GB18918-2002一級A規范。當投加量為30mg/L時,厭氧段釋磷、好氧段吸磷和缺氧段脫氮速率均為,可達到3.54 mgPO43-P/(g MLSS·h) 2.54 mgPO43--P/(g MLSS·h);和1.53 mgNOx-N/(gMLSS·h)。當乙酸鈉投加量為9mg/L和15mg/L時,體系在缺氧段呈現反硝化除磷現象,缺氧段吸磷速率分別為0.36mgPO43--P/(g MLSS·h)和0.02(mgPO43--P/(gMLSS·h)。綜上所述,乙酸鈉的投加量為30mg/L體系運行將更加穩定可靠。 |
