（PAM）是一種線型水溶性高分子，是水溶性高分子化合物中應(yīng)用最為廣泛的品種之一，PAM及其衍生物可以用作高效的絮凝劑、增稠劑、紙張?jiān)鰪?qiáng)劑以及液體的減阻劑，廣泛應(yīng)用于水處理、造紙、石油、煤炭、礦冶、地質(zhì)、輕紡、建筑等工業(yè)部門(mén)。 聚丙烯酰胺溶液的價(jià)格在8000元至12000元之間，我們計(jì)算出1噸聚丙烯酰胺溶液的藥費(fèi)為10元，那么處理1噸污水需要多少聚丙烯酰胺陰離子溶液？"通過(guò)大量的試驗(yàn)和各廠家的基本情況，總結(jié)出每噸污水所需的溶液量小于2~3kg。3~5kg計(jì)算處理一噸砂土，只要設(shè)備合適且不浪費(fèi)，處理成本低至0.3~0.5元，如果戰(zhàn)場(chǎng)選用自然降水無(wú)濾壓降低成本，一噸污水處理成本約為0.1元，因此每個(gè)老板的成本價(jià)格是可以接受的。    歡迎各洗砂場(chǎng)業(yè)主來(lái)電咨詢我公司河南安佳網(wǎng)環(huán)保聚丙烯酰胺，提高免費(fèi)試樣服務(wù)聯(lián)系號(hào)碼1583835697818838138890Costcalculationofsewagetreatment"。 Polyacrylamideanionisanecessaryagentforpressurefiltrationanddehydrationinthesandwashingfieldofasewageplant.ThecostofPAMisthefirstconsiderationofmanysandowners,includingtheuseofsedimentationspeedcirculatingwater.Itisknownthiceofonetonofpolyacrylamacceptabletoallbosses Welcomealltheownersofthesandwashingfieldtocallusforconsultation.Henananjiajingenvironmentalprotectionpolyacrylamideimprovedfreetrialsamplesendingservicecontactnumber:1583835697818838138890 非離子聚丙烯酰胺   用途： 1、污水處理劑 當(dāng)懸浮性污水顯酸性時(shí)，采用非離子聚丙烯酰胺作絮凝劑較為合適，這是PAM起吸附架橋作用，使懸浮的粒子產(chǎn)生絮凝沉淀，達(dá)到凈化污水的目的。也可用于自來(lái)水的凈化，尤其是和無(wú)機(jī)絮凝劑配合使用，在水處理中效果 水醋酸鈉（工業(yè)級(jí)) ??在平常假如我們常常運(yùn)用，能夠選擇干粉顆粒狀聚丙烯酰胺，The classification obtained by the method is different. If the ionic type can be divided into Yin, non, amphoteric and cationic polyacrylamide, if according to the shape, it can be divided into four shapes: colloid, laxity, emulsion and dry powder. Which of these four forms is more suitable for us? The company gives you some suggestions. Next is our experience. I hope you will be interested. In general, if we often use it, we can choose dry powder granular polyacrylamide. Because of its highest solid content, dry powder polyacrylamide is generally stored in dry and cool places for more than two years, but if mixed with solution, its storage time will be limited. Generally speaking, when the concentration of solution is 0.1%, non-ionic and anionic polyacrylamide will dissolve. The stability of cationic polyacrylamide solution depends on the concentration of the solution. For example, the more concentrated the solution is, the longer the storage time of 3%-5% solution is, but the 3%-5% solution can not be directly used to treat sewage. This solution needs to be diluted before use, and the PH value of cationic polyacrylamide solution is less than 5.5. Stability, if greater than 6.0, will be due to hydrolysis and failure, water medium dispersion polyacrylamide shelf life of six months. Therefore, polyacrylamide is still a better choice of solids, can be used with the mix, do not cause waste. Of course, we must pay attention to the conditions and taboos of preserving polyacrylamide. Polyacrylamide is more sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. In particular, iron ions are catalysts for the chemical degradation of all polyacrylamide. Therefore, in the manufacture, handling and storage of polyacrylamide solutions, we must try to avoid iron ions entering and touching the solution. The equipment should be made of plastics, stainless steel, FRP or carbon steel with surface coating resin.由于它的固含般情況下干粉聚丙烯酰胺在干燥、陰涼的當(dāng)?shù)厥羌拇娑暌陨系，但假如配成溶液的話，它的寄存時(shí)刻就有限了，一般說(shuō)，溶液濃度為0.1%的時(shí)候，非離子與陰離子聚丙烯酰胺溶液不會(huì)超過(guò)一周的時(shí)刻，陽(yáng)離子聚丙烯酰胺溶液則不會(huì)超過(guò)一天，而且溶液的穩(wěn)定性與溶液的濃度有關(guān)，配的濃度越濃，例如3%——5%的溶液寄存時(shí)刻越長(zhǎng)，但3%——5%的溶液不能直接去處理污水，這種在運(yùn)用前需要稀釋，陽(yáng)離子聚丙烯酰胺溶液PH值小于5.5的時(shí)后比較穩(wěn)定，假如大于6.0的話，就會(huì)由于水解的原因而失效，水介質(zhì)渙散型聚丙烯酰胺保質(zhì)期為六個(gè)月。 編號(hào)：20180109GD 產(chǎn)品批號(hào)：TS2017010721DE 技術(shù)工程標(biāo)：自然沉淀脫水 日期：20181109 品名 三水醋酸鈉 技術(shù)指標(biāo)名稱 檢測(cè)結(jié)果 含量 58-60% 外觀 無(wú)色或白色晶體 重金屬 ≦0.04% 水不溶物 ≦0.03% 注：水分由空氣濕度變化而變動(dòng)。濕度、含量變化由提供批樣樣品為準(zhǔn)。 化學(xué)性質(zhì)： 溶解比：762g/L(20℃)。 外觀：白色或類白色結(jié)晶 常溫常壓下穩(wěn)定，無(wú)色無(wú)味的結(jié)晶體，在空氣中可被風(fēng)化。易溶于水，微溶于乙醇，不溶23℃時(shí)失去結(jié)晶水。 主要用途： 適用于制造醫(yī)藥、燃料以及環(huán)保等方面， 染工業(yè)、醫(yī)藥、照相、電鍍、化學(xué)試劑及有機(jī)合成等。 醋酸鈉生產(chǎn)工藝 將含量15%的冰醋酸溶液取160 kg投入反應(yīng)釜中。在攪拌下加入25 kg純堿。中和至pH值為8,充分?jǐn)嚢璧么姿徕c水溶液。在60℃以下加熱濃縮至27°Bé冷卻結(jié)晶,同時(shí)用真空泵將產(chǎn)生的少量刺激氣體抽到廢氣吸收塔吸收，離心脫水得粗品。用水重結(jié)晶后得精品。離心脫水,干燥得成品。 反應(yīng)式如下 Na2CO3 2CH3COOH=2CH3COONa H2O CO2 NaOH CH3COOH=CH3COONA H2O 2、紡織工業(yè)助劑 添加一些化學(xué)品可配成化學(xué)資料，用于紡織品上漿。 3、防沙固沙 將非離子聚丙烯酰胺溶成存時(shí)間:隨著儲(chǔ)存時(shí)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(chǔ)存7天，陽(yáng)離子PAM溶液可以儲(chǔ)存24小時(shí)。這是由于酰胺基團(tuán)的水解和羥基含量的增加。尤其是陽(yáng)離子基團(tuán)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(dāng)溫度達(dá)到80 - 90℃時(shí)，1800萬(wàn)的分子量會(huì)在2 - 4小時(shí)內(nèi)降解到500萬(wàn)左右，并且降解會(huì)隨著溫度的升高而變得越來(lái)越快。在25℃的室溫下性能穩(wěn)定。    懸浮在有機(jī)溶劑中的單體水溶液與小液珠的聚合稱為懸浮聚合，也稱為珠聚合。懸浮聚合物主要由單體、引發(fā)劑、有機(jī)溶液和懸浮劑組成。引發(fā)劑溶解在單體水溶液中。分散劑也被稱為懸浮劑。其功能是在攪拌下將單體水溶液分散成小液珠，并將其懸浮在有機(jī)溶劑中，以防止聚合顆粒在聚合過(guò)程中相互粘附。產(chǎn)品的粒度一般為100-2000 μ m Storage time: With the increase of storag胺稱為聚氯化鋁或者絮凝劑等等。聚合氯化鋁和傳統(tǒng)的無(wú)機(jī)混凝劑的不同在：傳統(tǒng)無(wú)機(jī)混凝劑是低分子結(jié)晶鹽，聚合氯化鋁是由各種不同的化學(xué)物質(zhì)經(jīng)高溫高壓聚合而成，絮凝沉淀快速，對(duì)管道設(shè)備腐蝕性小，凈水效果優(yōu)異，能較好的去除水中各種有害重金屬離子。 銷售凝劑。聚合氯化鋁具有絮凝體生成快、沉降性能好、水中堿度消耗低的優(yōu)點(diǎn)，尤其對(duì)水溫、酸堿度、濁度和有機(jī)物含量的變化適應(yīng)性強(qiáng)。事實(shí)上，聚合氯化鋁的整個(gè)絮凝過(guò)程也是一個(gè)失穩(wěn)過(guò)程。所謂失穩(wěn)，就是讓膠體粒子失去穩(wěn)定性的過(guò)程。原本均勻分散在液體中的固體顆粒結(jié)合成大顆粒，然后沉淀出來(lái)，超過(guò)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(shí)間、水體特性等，F(xiàn)階段，由于它的諸多優(yōu)點(diǎn)，很受大家的歡迎。目前，我們還開(kāi)發(fā)了復(fù)合無(wú)機(jī)高分子絮凝劑。這類絮凝劑的絮凝特性和沉降性能會(huì)在聚合氯化鋁的水平上更進(jìn)一步，相信未來(lái)會(huì)占據(jù)很大的銷售市場(chǎng)！ 在處理污水時(shí)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(wú)論是在產(chǎn)品質(zhì)量上還是在產(chǎn)品價(jià)格上，任何消費(fèi)者都希望自己購(gòu)買的產(chǎn)品是優(yōu)異的，質(zhì)量才是消費(fèi)者選擇的一個(gè)重要標(biāo)準(zhǔn)。 先確定污水處理選用的產(chǎn)品種類，可以根據(jù)采購(gòu)凈水劑聚合氯化鋁的用途來(lái)說(shuō)，聚合氯化鋁可以分為工業(yè)級(jí)，飲水級(jí)，食品級(jí)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(gòu)時(shí)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(zhì)量，對(duì)聚合氯化鋁性能的分辯有直接幫助，可以從以下幾點(diǎn)鑒別聚合氯化鋁的性能： 1、重要的化學(xué)反應(yīng)，比方離子反應(yīng)。 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(xiàng)一：溶解攪拌 聚丙烯酰胺外觀為白色結(jié)晶體顆粒，一般為60-80目之間，在使用時(shí)需要用潔凈的自來(lái)水按配比濃度充分溶解，一般溶解攪拌時(shí)間不應(yīng)低于一小時(shí)。冬季氣溫較低時(shí)應(yīng)延長(zhǎng)溶解攪拌時(shí)間。很多時(shí)候應(yīng)溶解 攪拌時(shí)間過(guò)短造成PAM未充分溶解，在污水中無(wú)法有效的進(jìn)行吸附架橋、網(wǎng)捕等形式達(dá)到快速的絮凝效果。 聚丙烯酰胺使用注意事項(xiàng)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(shí)配置濃度為0.2%-0.5%之間(需根據(jù)污泥濃度大小來(lái)調(diào)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(zhì)過(guò)大時(shí)聚丙烯酰胺配置濃度應(yīng)增加。 聚丙烯酰胺使用注意事項(xiàng)：型號(hào)選擇 聚丙烯酰胺型號(hào)大致可分為常用三種：陰離子型、陽(yáng)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(wú)機(jī)污泥脫水使用。 不同類型聚丙烯酰胺的特性： 陽(yáng)離子聚丙烯酰胺適用于復(fù)雜水質(zhì)的絮凝、沉降、脫色、澄清等，城市污泥脫水、有機(jī)污泥脫水等。。 陰離子型適用于中性及弱堿性無(wú)機(jī)污水絮凝沉降、污泥脫水。 陽(yáng)離子型PAM適用于有機(jī)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(duì)較低，其通常作為珠粒懸浮在有機(jī)相中。因此，所用的有機(jī)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(qiáng)度也低于乳液聚合。懸浮聚合得到的產(chǎn)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(wú)機(jī)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(jié)束后，共沸脫水、分離、干燥，得到珠狀或粉末狀產(chǎn)品。在聚合過(guò)程中加入無(wú)機(jī)鹽氯化鈉、納米3或Na2NO3可以調(diào)節(jié)體系的表面張力，提高懸浮穩(wěn)定性，但對(duì)聚合過(guò)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(huì)增加產(chǎn)物的相對(duì)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(jī)械作用效果:攪拌可以提高PAM干粉的溶解速度，高強(qiáng)度攪拌速度會(huì)切斷聚丙烯酰胺的分子鏈，建議在線控制攪拌速度至60轉(zhuǎn)/分鐘，而不是使用高強(qiáng)度攪拌設(shè)備和高速輸送設(shè)備。 4、光照的影響:光照會(huì)升高溫度，溶解并降解聚丙烯酰胺，而紫外線的直接照射會(huì)迅速降解溶解。直接暴露在強(qiáng)光下3 - 5小時(shí)將使pam分子量降低30 - 50 5、雜質(zhì)的影響:溶解PAM干粉，優(yōu)選使用中性水，水的硬度大，或者含有雜質(zhì)，都會(huì)影響PAM的粘度和使用效果 0.3%濃度加入交聯(lián)劑，噴灑在沙漠上可起到防沙固沙的作用。 4、土壤保濕劑 用作土壤保濕劑和各種改性聚丙烯酰胺的基礎(chǔ)原料。 陽(yáng)離子聚丙烯酰胺: 用途：1、污泥脫水 根據(jù)污泥性質(zhì)可選用本產(chǎn)品的相應(yīng)牌號(hào)，可有效在污泥進(jìn)入壓濾之前進(jìn)行重力污泥脫水。脫水時(shí)，產(chǎn)生絮團(tuán)大，不粘濾布，在壓濾時(shí)不流散、用量少、脫水效率高、泥餅含水率在80%以下。 2、污水和有機(jī)廢水的處理 本產(chǎn)品在酸性或堿性介質(zhì)中均呈現(xiàn)陽(yáng)電性，這樣對(duì)污水中懸浮顆粒帶陰電荷的污水進(jìn)行絮凝沉淀，澄清是極為有效的，如酒精廠廢水、啤酒廠廢水、味精廠廢水、制糖廠廢水、肉食品廠廢水、飲料廠廢水、紡織印染廠的廢水等。用陽(yáng)離子聚丙烯酰胺要比用陰離子聚丙烯酰胺，非離子聚丙烯酰胺或無(wú)機(jī)鹽效果要高數(shù)倍或數(shù)十倍，因?yàn)檫@類廢水普遍帶有陰電荷。 3、自來(lái)水廠水處理絮凝劑 該產(chǎn)品具有用量少、效果好、成本低等特點(diǎn)。特別是和無(wú)機(jī)絮凝劑復(fù)配使用效果更好。 4、油田化學(xué)品 如粘土防膨劑、油田酸化用稠化劑品等。(PAM) is a linear water-soluble polymer, which is one of the most widely used varieties of water-soluble polymer compounds. PAM and its derivatives can be used as efficient flocculants, thickeners, paper enhancers and liquid drag reducing agents. They are widely used in water treatment, paper making, petroleum, coal, mining, metallurgy, geology, light textile, construction and other industrial sectors. Nonionic polyacrylamide Uses: 1. When the suspended sewage is acidic, it is more appropriate to use non-ionic polyacrylamide as flocculant. This is because PAM acts as an adsorption bridge to make suspended particles flocculate and precipitate, so as to purify the sewage. It can also be used to purify tap water, especially in combination with inorganic flocculants, and has the best effect in water treatment. 2. Adding some chemicals to textile industry auxiliaries can be used to compose chemical data for textile sizing. 3. Dissolve non-ionic polyacrylamide into 0.3% concentration and add crosslinking agent in sand control and sand fixation. Spraying on desert can play a role in sand control and sand fixation. 4. Soil moisturizers are used as basic materials of soil moisturizers and various modified polyacrylamides. Cationic polyacrylamide: Usage: 1. Sludge dewatering can choose the corresponding brand of this product according to the nature of sludge, which can effectively dewatering gravity sludge before the sludge enters the filter press. When dewatering, it produces large flocs, non-sticking filter cloth, non-dispersing, less dosage, high dewatering efficiency and less than 80% moisture content of mud cake. 2. The treatment of sewage and organic wastewater shows positive electricity in acidic or alkaline medium, so flocculation and precipitation of sewage with negative charge of suspended particles in sewage is very effective, such as wastewater from alcohol factory, brewery, monosodium glutamate factory, sugar factory, meat food factory, beverage factory and textile printing and dyeing factory. Cationic polyacrylamide is several or tens of times more effective than anionic polyacrylamide, nonionic polyacrylamide or inorganic salts, because such wastewater generally has negative charges. 3. Water treatment flocculant in Waterworks has the characteristics of low dosage, good effect and low cost. Especially, the combination of inorganic flocculant and inorganic flocculant has better effect. 4. Oilfield chemicals such as clay anti-swelling agents and thickeners for oilfield acidification. 5. Paper reinforcer cationic PAM is a water-soluble cationic polymer containing carbamoyl group. It has the functions of reinforcement, retention and filter aid. It can effectively improve the strength of paper. At the same time, the product is also a highly effective dispersant. Anionic polyacrylamide Uses: 1. Industrial wastewater treatment has the best effect on sewage treatment, such as coarse suspended particles, high concentration, positive charges of particles, neutral or alkaline PH value of water, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. 2. Drinking water treatment in many Waterworks of our country comes from rivers. The content of sediment and minerals is high and turbid. Although it can't meet the requirements after sedimentation and filtration, it needs to add flocculant. The dosage of flocculant is 1/50 of inorganic flocculant, but the effect is several times that of inorganic flocculant. Inorganic flocculant and cationic flocculation of our company can be used for river water seriously polluted by organic matter. The effect of acrylamide is better. 3. Recycling of lost starch grains in starch factories and alcohol factories now contains a lot of starch in the wastewater of many starch factories. Anionic polyacrylamide is added to flocculate and precipitate starch particles, and then the precipitate is filtered into cake shape by pressure filter, which can be used as feed. Alcohol in alcohol factories can also be dehydrated by anionic polyacrylamide and reclaimed by pressure filter. 5、 造紙助劑 陽(yáng)離子PAM紙張?jiān)鰪?qiáng)劑是一種含氨基甲；乃苄躁(yáng)離子聚合物，具有增強(qiáng)、助留、助濾等功能，可有效地提高紙的強(qiáng)度，同時(shí)該產(chǎn)品也是一種高效分散劑。 陰離子聚丙烯酰胺 用途：1、工業(yè)廢水處理 對(duì)于懸浮顆粒較粗、濃度高、粒子帶陽(yáng)電荷，水的PH值為中性或堿性的污水，鋼鐵廠廢水、電鍍廠廢水、冶金廢水、洗煤廢水等污水處理，效 2、飲用水處理 我國(guó)很多自來(lái)水廠的水源來(lái)自江河，泥沙及礦物質(zhì)含量高，比較渾濁，雖經(jīng)過(guò)沉淀過(guò)濾，仍不能達(dá)到要求，需要投加絮凝劑，投加量是無(wú)機(jī)絮凝劑的1/50，但效果是無(wú)機(jī)絮凝劑的幾倍，對(duì)于機(jī)物污染嚴(yán)重的江河水可采用無(wú)機(jī)絮凝劑和我公司的陽(yáng)離子聚丙烯酰胺配合使用效果更好。 3、淀粉廠及酒精廠的流失淀粉酒糟的回收 現(xiàn)在很多淀粉廠的廢水內(nèi)含淀粉很多，現(xiàn)投加陰離子聚丙烯酰胺，使淀粉微粒絮凝沉淀，然后將沉淀物經(jīng)壓濾機(jī)壓濾變成餅狀，可作飼料，酒精廠的酒精也可采用陰離子聚丙烯酰胺脫水，壓濾進(jìn)行回收。 |
