在全球流行的情况下,净水工业的道路在哪里?
说,我们会提到聚丙烯酰胺产品的分子量,但有些客户会询问它们的粘度。聚丙烯酰胺的分子量与其粘度有一定的关系。确定聚丙烯酰胺分子量的方法之一是测量其粘度方法。可以看出,聚丙烯酰胺的粘度和分子量之间存在一定的关系!
在正常情况下,聚丙烯酰胺的分子量越高,粘度越大,因为聚丙烯酰胺大分子是细小的长链状体,并且在溶液中的运动阻力很大。粘度的本质是溶液中的摩擦量,也称为内摩擦系数。各种高分子有机化合物的溶液具有高粘度并随着分子量的增加而增加。
经过我们聚丙烯酰胺多年的研究,聚丙烯酰胺的絮凝性能与其溶液粘度直接相关。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。产品性能越好;如果其粘度因某些因素而降低,其絮凝性能将不可避免地下降。然而,聚丙烯酰胺溶液的粘度受许多其它因素的影响,例如温度,湿度,溶解过程中的要弄清楚聚合氯化铝与聚丙烯酰胺哪个是絮凝剂,首先我就要弄清楚混凝剂与絮凝剂的区别。混凝是指药剂投加进水中水解后对废水中胶体进行压缩电双分子层,使得脱稳、破乳凝聚形成絮体的一个过程。絮凝则是将各小的絮体,胶体颗粒进行吸附架桥,网捕沉淀,主要外表为粘结成大块的絮体现象,絮凝剂不具备凝聚作用。混凝=凝聚+絮凝。
聚丙烯酰胺是一种新型的无机盐铁系高分子水处理药剂,具有对废水中的溶质、胶体和悬浮物具有电子中和的作用。特别是高聚物形态使它废水中溶解后生生长线的状,两端可将水中的这些物质进行吸附架桥,聚丙烯酰胺的这些长线状会相互交叉,形成一张张网对水中的小颗粒进行卷扫,进而凝聚沉淀。由此看来,聚丙烯酰胺是典型的高分子絮凝剂。而絮凝剂与助凝剂都属于混凝剂中的一种,因此,聚丙烯酰胺既是絮凝剂又是混凝剂。
聚合氯化铝在投加入废水中后,利用其高分子量立体网状空间结构,能够将废水中的混凝所形成的小的絮凝体粘结起来,形成大的絮凝帆花,使得高分子链互缠交联,形成网捕,从而使絮凝体结构增大变粗,从而达到加速固体和液体分离,较后形成沉淀。但是聚合氯化铝不具备凝聚作用,所以其只具有絮凝作用,只能作为絮凝剂。废水处置中,经常采用聚丙烯酰胺+聚合氯化铝联合使用。这种混凝与絮凝相结合的配比使用药剂,不但降低了废水处置本钱,又大大提高了其污染物的絮凝速度与效果。
聚合氯化铝的包装一般为编织袋或牛皮纸袋,防潮,防漏,相对坚韧。主要规格为聚丙烯酰胺5公斤/袋或25公斤/袋。

非离子聚丙烯酰胺
用途: 1、污水处理剂 当悬浮性污水显酸性时,采用非离子聚丙烯酰胺作絮凝剂较为合适,这是PAM起吸附架桥作用,使悬浮的粒子产生絮凝沉淀,达到净化污水的目的。也可用于自来水的净化,尤其是和无机絮凝剂配合使用,在水处理中效
2、纺织工业助剂 添加一些化学品可配成化学资料,用于纺织品上浆。
3、防沙固沙 将非离子聚丙烯酰胺溶成0.3%浓度加入交联剂,喷洒在沙漠上可起到防沙固沙的作用。
4、土壤保湿剂 用作土壤保湿剂和各种改性聚丙烯酰胺的基础原料。
阳离子聚丙烯酰胺:
用途:1、污泥脱水 根据污泥性质可选用本产品的相应牌号,可有效在污泥进入压滤之前进行重力污泥脱水。脱水时,产生絮团大,不粘滤布,在压滤时不流散、用量少、脱水效率高、泥饼含水率在80%以下。
2、污水和有机废水的处理 本产品在酸性或碱性介质中均呈现阳电性,这样对污水中悬浮颗粒带阴电荷的污水进行絮凝沉淀,澄清是极为有效的,如酒精厂废水、啤酒厂废水、味精厂废水、制糖厂废水、肉食品厂废水、饮料厂废水、纺织印染厂的废水等。用阳离子聚丙烯酰胺要比用阴离子聚丙烯酰胺,非离子聚丙烯酰胺或无机盐效果要高数倍或数十倍,因为这类废水普遍带有阴电荷。
3、自来水厂水处理絮凝剂 该产品具有用量少、效果好、成本低等特点。特别是和无机絮凝剂复配使用效果更好。
4、油田化学品 如粘土防膨剂、油田酸化用稠化剂品等。(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 p
lant 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、 造纸助剂 阳离子PAM纸张增强剂是一种含氨基甲酰基的水溶性阳离子聚合物,具有增强、助留、助滤等功能,可有效地提高纸的强度,同时该产品也是一种高效分散剂。
阴离子聚丙烯酰胺
用途:1、工业废水处理 对于悬浮颗粒较粗、浓度高、粒子带阳电荷,水的PH值为中性或碱性的污水,钢铁厂废水、电镀厂废水、冶金废水、洗煤废水等污水处理,效
2、饮用水处理 我国很多自来水厂的水源来自江河,泥沙及矿物质含量高,比较浑浊,虽经过沉淀过滤,仍不能达到要求,需要投加絮凝剂,投加量是无机絮凝剂的1/50,但效果是无机絮凝剂的几倍,对于机物污染严重的江河水可采用无机絮凝剂和我公司的阳离子聚丙烯酰胺配合使用效果更好。
3、淀粉厂及酒精厂的流失淀粉酒糟的回收 现在很多淀粉厂的废水内含淀粉很多,现投加阴离子聚丙烯酰胺,使淀粉微粒絮凝沉淀,然后将沉淀物经压滤机压滤变成饼状,可作饲料,酒精厂的酒精也可采用阴离子聚丙烯酰胺脱水,压滤进行回收。
