2020 is destined to be a tough year for donai, with tears, feelings and short joy after victory. In the face of the global explosive epidemic, how will our water purification industry develop Henan anjiajing environmental protection technology, devoted to the production of polyacrylamide poly aluminum chloride poly ferric sulfate? Over 20 years, we have experienced many experiences in Central China, neighboring Hubei Province The epidemic situation is very serious. In March, under the leadership of the government and the command of the party, we basically defeated the epidemic situation. The enterprises returned to work and started to produce polyaluminium chloride polyacrylamide, which basically entered the normal stage. Because our workers are basically the raw materials required by the mature production technology of local employees, and also the polyacrylamide that can be purchased in the province As a necessary medicine for sewage treatment, polyaluminium chloride is indispensable in every industry of every enterprise, but the impact is not on our internal production, but on the external production of many small enterprises, which can not use the most sand washing food sewage plants, sewage plants, which can not stop, the most impact is that small manufacturers, we have a strong production force to settle down With the support of capital support and old customers, the daily shipment volume is more than 100 tons, and the price is also provided to customers with the support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，致力于綠色環保可再生資源的繼續使用，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：
多人在使用前，都知道需要經過進行小試后確定聚合氯化鋁的使用方案后在進行大量的投加使用，其中小試需要得到的有聚合氯化鋁的類型、含量、溶解濃度、使用方法等。那么如何進行聚合氯化鋁的小試呢？河南環保科技有限公司為您介紹一下。
用滴管將聚合氯化鋁的水溶液慢慢添加到污水中，并使用玻璃棒進行攪拌，觀察污水的絮凝效果，如果出現礬花就表示聚合氯化鋁的絮凝效果較好，然后將不同的量的聚合氯化鋁水溶液添加到污水的樣品中，攪拌靜置一段時間后觀察看哪個污水樣品更加干凈清澈。在使用聚合氯化鋁的過程中，有時候需要添加一些其他的助凝劑如聚丙烯酰胺等，這樣會加快污水的絮凝和沉淀達到更加好的處理效果。ties. 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。
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，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.
(4) 聚丙烯酰胺絮凝劑預處置普通占整個污泥處置費用較高的比例，因而，聚丙烯酰胺的優加率的合理肯定對降低污泥預處置費用相當關鍵。對選擇聚丙烯酰胺的實驗辦法的研討已展開多年，包括比阻、CST值、污泥流變性、分別液粘度、活動電流等。The synthesis and process physical properties of AM polyacrylamide: PAM is prepared by direct reaction of acrylonitrile with water under the action of framework copper catalyst, and then dried by ion exchange polymerization. The process is as follows: catalyst: catalytic hydration CH2 = CHCN + H2 humidity CH2 = CHCONH2 polymerization nCH2 = CHCONH2 - initiator - CH2CHCONH2
Industrial uses of polyacrylamide: Polyacrylamide (PAM) has high molecular weight, good water solubility, adjustable molecular weight, and can introduce various ionic groups to obtain specific properties. Low molecular weight is an effective additive or stabilizer for dispersing materials. High molecular weight is an important flocculant. It can produce hydrophilic and water-insoluble gel, which has good adhesion to many groups of surface and dissolved substances. Because of the above properties, PAM is widely used in flocculation, thickening, drag reduction, glue imitation, bonding, scale inhibition and other fields.
Anionic polyacrylamide can be used in different molecular weights according to different uses and user's requirements for product performance.
In industrial wastewater treatment, especially for suspended particles, coarser, high concentration, positive charged particles, neutral and alkaline wastewater such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater treatment effect is very good.
In drinking water treatment. The water source of many Waterworks in our country is low in mud and high in mineral content, which is turbid. Although it has been treated by precipitation, it still can not meet the requirements. Flocculants are needed to make the water quality clear. Many waterworks use inorganic flocculants, but the amount of inorganic flocculants is large, resulting in poor effect of sludge increase. Anionic polyacrylamide acrylamide monomer was 0.012%. The molecular weight of anionic PAM was 12.5 million and the content of acrylamide monomer was 0.013%. The concentration of two kinds of PAM is 0.05%. They are used after refrigeration for 24 hours.
(1) PAM pretreatment sludge takes lOml sludge and puts it into a 300 ml beaker. Six-unit mixers are used to mix at 1130 RPM speed for 30 seconds, and then the PAM is added to the sludge quickly and quantitatively. The PAM is stirred at lOOrpm speed for 30 seconds, then the speed of the mixer is reduced to 20-30 rpm and the slow stirring speed is 60 seconds to promote flocculation. The specific resistance of pretreated sludge, capillary water absorption time (CST), the viscosity of filtrate and the viscosity of centrifuge were measured.
(2) The specific resistance is tested by Brinell funnel according to the test method proposed by Coackley. The diameter of Brinell funnel is 80 mm. The filter paper is made of 70 mm medium speed filter paper. The vacuum degree of the test is controlled to 0.01 MPa. The experiment was repeated three times to get the average value.
(3) In order to reduce specific resistance and improve sludge dewatering effect, sludge should be pretreated before sludge dewatering. Sludge pretreatment methods include freeze-thaw pretreatment, heat treatment, acid treatment, alkali treatment, lime pretreatment and polymer flocculant pretreatment. Polymer flocculant polyacrylamide (PAM) pretreatment is the most widely used pretreatment method at home and abroad.
(6)依據CST值變化肯定PAM最投加率與測定比阻得到的最投加率分歧。并且CST值與比阻之間存在線性相關關系，比阻值越大，CST值越大，因而能夠采用CST值來近似替代污泥比阻反映污泥的脫水性能。與比阻相比，cST值測定快速、煩瑣，不但適用于實驗室研討，還可用于消費現場，快速理解污泥脫水性能的變化，使操作人員及時調楚PAM投加率，儉省藥劑費。is used as flocculant, and the dosage is inorganic flocculant. One fiftieth of the flocculants, but the effect is several times to dozens of times that of inorganic flocculants. Especially the polyacrylamide produced by our company, the residual monomers have reached the food grade (less than 0.05%), close to the advanced level abroad, non-toxic, more suitable for the treatment of drinking water, and better for the use of organic pollutants polluted river water and anionic polyacrylamide.
Polyacrylamide is used to recover lost starch and distiller's grains in starch and alcohol factories. At present, the starch in the waste water discharged by many starch factories is very high. After discharging, it affects the environment, wastes resources, and adds PAM to make starch precipitate. The precipitate is filtered by pressure filter to become cake and can be used as feed. A large number of distillers'grains in the alcohol factories are processed by this process. A certain alcohol factory in Heilongjiang Province uses polyacrylamide as flocculant, which recycles the distillers' grains and obtains a great deal of experience. Economic benefits.
Polyacrylamide is used as water shutoff agent for profile control and water shutoff in Oilfield and oil displacement agent for tertiary oil recovery.
Polyacrylamide is used as paper-making additive. PAM is widely used in paper-making. It can be used as long fiber paper-making dispersant, wet and dry reinforcing agent, retention aid, filter aid and flocculant of paper-making wastewater.
The latest type of water treatment agent polyacrylamide, when treating sewage and water in many occasions, the combination of anionic polyacrylamide and cationic polyacrylamide has a very significant and synergistic effect than using one kind of ionic polyacrylamide alone. The ability of PAM to reduce surface tension is much greater than the ability of cations or anions existing alone under the same conditions. For the requirement of low surface tension, both anionic and cationic polyacrylamide need to be used at the same time. If they are used improperly, white precipitates will be produced and the effect of using them will be lost. PAM has the characteristics of amphoteric ions. It can complete the coordination of anions and cations. There is no precipitate on the surface. Especially, it is more convenient to use PAM as a flocculant because of the complex water quality or the changeable nature of water.
The sludge used in sewage pretreatment is taken from the sedimentation tank with Qiantang River water as its source of water, and PAC is used as a flocculant in the water plant. The sludge was naturally concentrated to a solid content of 2.7%-2.8%. The organic matter content in the sludge was 12.1%, SJ content was 52.1%, Al content was determined. The content was 20.2%. There are three types of PAM: cationic, anionic and nonionic. Non-ionic PAM dissolves slowly and is generally not used for sludge pretreatment. Therefore, only two representative cationic polyacrylamides and anionic polyacrylamides are selected in the experiment. The molecular weight of cationic PAM was 12 million and the content of
