(PAM)是一種線型水溶性高分子,是水溶性高分子化合物中應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、紙張增強劑以及液體的減阻劑,廣泛應用于水處理、造紙、石油、煤炭、礦冶、地質(zhì)、輕
在全球流行的情況下,凈水工業(yè)的道路在哪里?
說,我們會提到聚丙烯酰胺產(chǎn)品的分子量,但有些客戶會詢問它們的粘度。聚丙烯酰胺的分子量與其粘度有一定的關(guān)系。確定聚丙烯酰胺分子量的方法之一是測量其粘度方法??梢钥闯?,聚丙烯酰胺的粘度和分子量之間存在一定的關(guān)系!
在正常情況下,聚丙烯酰胺的分子量越高,粘度越大,因為聚丙烯酰胺大分子是細小的長鏈狀體,并且在溶液中的運動阻力很大。粘度的本質(zhì)是溶液中的摩擦量,也稱為內(nèi)摩擦系數(shù)。各種高分子有機化合物的溶液具有高粘度并隨著分子量的增加而增加。
經(jīng)過我們聚丙烯酰胺多年的研究,聚丙烯酰胺的絮凝性能與其溶液粘度直接相關(guān)。聚丙烯酰胺的粘度越高,性能越好,即聚丙烯酰胺的分子量越高。產(chǎn)品性能越好;如果其粘度因某些因素而降低,其絮凝性能將不可避免地下降。然而,聚丙烯酰胺溶液的粘度受許多其它因素的影響,例如溫度,濕度,溶解過程中的要弄清楚聚合氯化鋁與聚丙烯酰胺哪個是絮凝劑,首先我就要弄清楚混凝劑與絮凝劑的區(qū)別?;炷侵杆巹┩都舆M水中水解后對廢水中膠體進行壓縮電雙分子層,使得脫穩(wěn)、破乳凝聚形成絮體的一個過程。絮凝則是將各小的絮體,膠體顆粒進行吸附架橋,網(wǎng)捕沉淀,主要外表為粘結(jié)成大塊的絮體現(xiàn)象,絮凝劑不具備凝聚作用。混凝=凝聚+絮凝。
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(zhì)、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(zhì)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(wǎng)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(wǎng)狀空間結(jié)構(gòu),能夠?qū)U水中的混凝所形成的小的絮凝體粘結(jié)起來,形成大的絮凝帆花,使得高分子鏈互纏交聯(lián),形成網(wǎng)捕,從而使絮凝體結(jié)構(gòu)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(jīng)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(jié)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。

紡、建筑等工業(yè)部門。
非離子聚丙烯酰胺
用途: 1、污水處理劑 當懸浮性污水顯酸性時,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,達到凈化污水的目的。也可用于自來水的凈化,尤其是和無機絮凝劑配合使用,在水處理中效
2、紡織工業(yè)助劑 添加一些化學品可配成化學資料,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原料。
陽離子聚丙烯酰胺:
用途:1、污泥脫水 根據(jù)污泥性質(zhì)可選用本產(chǎn)品的相應牌號,可有效在污泥進入壓濾之前進行重力污泥脫水。脫水時,產(chǎn)生絮團大,不粘濾布,在壓濾時不流散、用量少、脫水效率高、泥餅含水率在80%以下。
2、污水和有機廢水的處理 本產(chǎn)品在酸性或堿性介質(zhì)中均呈現(xiàn)陽電性,這樣對污水中懸浮顆粒帶陰電荷的污水進行絮凝沉淀,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機鹽效果要高數(shù)倍或數(shù)十倍,因為這類廢水普遍帶有陰電荷。
3、自來水廠水處理絮凝劑 該產(chǎn)品具有用量少、效果好、成本低等特點。特別是和無機絮凝劑復配使用效果更好。
4、油田化學品 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, bllurgy, 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 crossbing 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 p
lant wastewater, electroplating plant wastewater, bllurgical 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 陽離子PAM紙張增強劑是一種含氨基甲酰基的水溶性陽離子聚合物,具有增強、助留、助濾等功能,可有效地提高紙的強度,同時該產(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 對于懸浮顆粒較粗、濃度高、粒子帶陽電荷,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 我國很多自來水廠的水源來自江河,泥沙及礦物質(zhì)含量高,比較渾濁,雖經(jīng)過沉淀過濾,仍不能達到要求,需要投加絮凝劑,投加量是無機絮凝劑的1/50,但效果是無機絮凝劑的幾倍,對于機物污染嚴重的江河水可采用無機絮凝劑和我公司的陽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,壓濾進行回收。
