興義市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(lián)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(fā)系統(tǒng)、單體的比率及濃度等。 上面是比較學術型,如果看不懂沒聯(lián)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,分子鏈不斷伸展存時間:隨著儲存時間的增加,PAM溶液降解越多,粘度越低,絮凝效果越差。通常,陰離子PAM溶液可以儲存7天,陽離子PAM溶液可以儲存24小時。這是由于酰胺基團的水解和羥基含量的增加。尤其是陽離子基團的影響更為明顯。由于分子鏈剛性的增加,酰胺基除去NH3生成酰亞胺基。 2、溫度影響: 0.1液體,當溫度達到80 - 90 聚丙烯酰胺是一種新型的無機鹽鐵系高分子水處理藥劑,具有對廢水中的溶質、膠體和懸浮物具有電子中和的作用。特別是高聚物形態(tài)使它廢水中溶解后生生長線的狀,兩端可將水中的這些物質進行吸附架橋,聚丙烯酰胺的這些長線狀會相互交叉,形成一張張網對水中的小顆粒進行卷掃,進而凝聚沉淀。由此看來,聚丙烯酰胺是典型的高分子絮凝劑。而絮凝劑與助凝劑都屬于混凝劑中的一種,因此,聚丙烯酰胺既是絮凝劑又是混凝劑。 聚合氯化鋁在投加入廢水中后,利用其高分子量立體網狀空間結構,能夠將廢水中的混凝所形成的小的絮凝體粘結起來,形成大的絮凝帆花,使得高分子鏈互纏交聯(lián),形成網捕,從而使絮凝體結構增大變粗,從而達到加速固體和液體分離,較后形成沉淀。但是聚合氯化鋁不具備凝聚作用,所以其只具有絮凝作用,只能作為絮凝劑。廢水處置中,經常采用聚丙烯酰胺+聚合氯化鋁聯(lián)合使用。這種混凝與絮凝相結合的配比使用藥劑,不但降低了廢水處置本錢,又大大提高了其污染物的絮凝速度與效果。 聚合氯化鋁的包裝一般為編織袋或牛皮紙袋,防潮,防漏,相對堅韌。主要規(guī)格為聚丙烯酰胺5公斤/袋或25公斤/袋。 沉降性能好、水中堿度消耗低的優(yōu)點,尤其對水溫、酸堿度、濁度和有機物含量的變化適應性強。事實上,聚合氯化鋁的整個絮凝過程也是一個失穩(wěn)過程。所謂失穩(wěn),就是讓膠體粒子失去穩(wěn)定性的過程。原本均勻分散在液體中的固體顆粒結合成大顆粒,然后沉淀出來,超過了凈水的目的。影響其有效性的因素也很多,如溶液的PH值、溫度、攪拌速度、攪拌時間、水體特性等。現(xiàn)階段,由于它的諸多優(yōu)點,很受大家的歡迎。目前,我們還開發(fā)了復合無機高分子絮凝劑。這類絮凝劑的絮凝特性和沉降性能會在聚合氯化鋁的水平上更進一步,相信未來會占據(jù)很大的銷售市場! 在處理污水時怎么樣選擇適用的聚合氯化鋁,在處理污水通常使用聚合氯化鋁,無論是在產品質量上還是在產品價格上,任何消費者都希望自己購買的產品是優(yōu)異的,質量才是消費者選擇的一個重要標準。 先確定污水處理選用的產品種類,可以根據(jù)采購凈水劑聚合氯化鋁的用途來說,聚合氯化鋁可以分為工業(yè)級,飲水級,食品級等等,不同行業(yè)使用的種類也不同,凈水劑聚合氯化鋁使用范圍較為廣泛,水處理是凈水劑聚合氯化鋁的重要方面,在具體選購時還是要依據(jù)水處理的效果。 聚合氯化鋁凈水藥劑的外觀,顏色,氣味,澄清度,固體性狀等等可以直接看出水處理藥劑的真假以及質量,對聚合氯化鋁性能的分辯有直接幫助,可以從以下幾點鑒別聚合氯化鋁的性能: 1、重要的化學反應,比方離子反應。 2、酸堿度,正常為1%水溶液的酸堿度為依據(jù)。使用注意事項一:溶解攪拌 聚丙烯酰胺外觀為白色結晶體顆粒,一般為60-80目之間,在使用時需要用潔凈的自來水按配比濃度充分溶解,一般溶解攪拌時間不應低于一小時。冬季氣溫較低時應延長溶解攪拌時間。很多時候應溶解 攪拌時間過短造成PAM未充分溶解,在污水中無法有效的進行吸附架橋、網捕等形式達到快速的絮凝效果。 聚丙烯酰胺使用注意事項二:配置濃度 聚丙烯酰胺配置濃度一般為0.1%-0.3%用于即可適用于絮凝沉淀(需根據(jù)PAM分子量大小或根據(jù)沉淀速度而定)。城市和工業(yè)污泥脫水時配置濃度為0.2%-0.5%之間(需根據(jù)污泥濃度大小來調配配置濃度)。 PAM配置濃度的大小完全取決于污水、污泥的濃度,污水中雜質過大時聚丙烯酰胺配置濃度應增加。 聚丙烯酰胺使用注意事項:型號選擇 聚丙烯酰胺型號大致可分為常用三種:陰離子型、陽離子型、非離子型,陰離子適用于污水絮凝、沉淀、助降、澄清等,也可用于無機污泥脫水使用。 不同類型聚丙烯酰胺的特性: 陽離子聚丙烯酰胺適用于復雜水質的絮凝、沉降、脫色、澄清等,城市污泥脫水、有機污泥脫水等。。 陰離子型適用于中性及弱堿性無機污水絮凝沉降、污泥脫水。 陽離子型PAM適用于有機污泥的絮凝沉降、污泥脫水。 非離子型聚丙烯酰胺更適用弱酸性污水絮凝沉降及污泥脫水。ize of the product is generally 100-2000 um. 2、乳液聚合的不同之處在于單體溶液的分散程度相對較低,其通常作為珠粒懸浮在有機相中。因此,所用的有機載體是比重較大的溶劑,如二甲苯、甲基氯乙烯等。分散劑通常不使用高活性乳化劑;攪拌強度也低于乳液聚合。懸浮聚合得到的產品為顆粒狀,使用方便。 3、在懸浮聚合溶液中,在懸浮劑如Span60、無機酰胺、C12-C18脂肪酸鈉或乙酸丁酸纖維的存在下,丙烯酰胺水溶液在汽油、二甲苯和甲基氯乙烯中形成穩(wěn)定的懸浮液以引發(fā)聚合。懸浮聚合結束后,共沸脫水、分離、干燥,得到珠狀或粉末狀產品。在聚合過程中加入無機鹽氯化鈉、納米3或Na2NO3可以調節(jié)體系的表面張力,提高懸浮穩(wěn)定性,但對聚合過程影響不大。然而,加入少量的單羧酸鹽、二羧酸鹽或多羧酸鹽通常會增加產物的相對分子量并降低聚合速率The dispersion of monomer solution is relatively low, and it is usually suspended in organic phase as beads. Therefore, the organic carriers used are solvents with large proportion, such as xylene, methyl vinyl chloride and so on. Dispersants usually do not use highly active emulsifiers, and the stirring strength is lower than that of emulsion polymerization. The product obtained by suspension polymerization is granular and easy to use. 3. In suspension polymerization solution, in the presence of suspension agents such as Span60, inorganic amides, C12-C18 fatty acid sodium or butyric acid acetate fibers, acrylamide aqueous solution forms stable suspensions in gasoline, xylene and methyl vinyl chloride to initiate polymerization. After suspension polymerization, azeotropic dehydration, separation and drying were carried out to obtain beaded or powdered products. Adding inorganic salts such as sodium chloride, nano-3 or Na2NO3 during the polymerization process can adjust the surface tension of the system and improve the suspension stability, but it has little effect on the polymerization process. However, the addition of small amounts of monocarboxylate, dicarboxylate or polycarboxylate usually increases the relative molecular weight of the product and reduces the polymerization rate. 3. Mechanical effect: Stirring can improve the dissolution rate of PAM dry powder. High stirring speed will cut off the molecular chain of polyacrylamide. It is suggested that the stirring speed be controlled online to 60 rpm/min instead of using high-strength stirring equipment and high-speed conveying equipment. 4. The influence of illumination: illumination will raise temperature, dissolve and degrade polyacrylamide, while direct ultraviolet irradiation will quickly degrade and dissolve. Direct exposure to intense light for 3 - 5 hours will reduce the molecular weight of PAM by 30 - 50 5. Impurities: Dissolving PAM powder, optimizing the use of neutral water, high hardness of water, or containing impurities, will affect the viscosity and use effect of PAM. 3、機械作用效果:攪拌可以提高PAM干粉的溶解速度,高強度攪拌速度會切斷聚丙烯酰胺的分子鏈,建議在線控制攪拌速度至60轉/分鐘,而不是使用高強度攪拌設備和高速輸送設備。 4、光照的影響:光照會升高溫度,溶解并降解聚丙烯酰胺,而紫外線的直接照射會迅速降解溶解。直接暴露在強光下3 - 5小時將使pam分子量降低30 - 50 5、雜質的影響:溶解PAM干粉,優(yōu)選使用中性水,水的硬 ![]() ![]() ![]() ![]() ion 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(yè)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(fā)展來看,陽離子型聚丙烯酰胺的發(fā)展都將有更快的增速。 3、目前,PAM產品在我國的能源戰(zhàn)略、節(jié)水戰(zhàn)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(huán)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(yè)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. 府和有關企業(yè)對污水處理事業(yè)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(yè)擬建聚丙烯酰胺項目主要是針對城市污水處理。據(jù)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(yè)的應 |
