- 非离子聚丙烯酰胺
- 阴离子聚丙烯酰胺
- 阳离子聚丙烯酰胺
非離子絮凝劑，简称NPAM，是线状高分子聚合物，分子量在500-1200万之间，固体产品外观为白色粉颗，液态为无色粘稠胶体状，易溶于水，几乎不溶于有机溶剂。应用时宜在常温下溶解，温度超过150℃时易分解。属非危险品、无毒、无腐蚀性。固体PAM有吸湿性、絮凝性、粘合性、降阻性、增稠性、同时稳定性好。
由于非离子不带离子型官能团，因此絮凝性能受废水PH值和盐类影响较小，在酸性条件下絮凝效果优于阴离子，絮体强度比阴离子强。
应用领域有：
1、用于工业上的固液分离过程，包括沉降、澄清、浓缩及污泥脱水等工艺，应用的主要行业有：城市污水处理、造纸工业、食品加工业、石化工业、冶金工业、选矿工业、染色工业和制糖工业及各种工业的废水处理。污水水体成酸性时，经常需要使用非离子聚丙烯酰胺配合聚合氯化铝等无机絮凝剂来处理，沉降速度快，处理效果好。
4、在采矿、选煤行业中可作矿山废水、洗煤废水的澄清剂。在洗煤尾渣离心分离过程、煤粉煤泥沉淀过滤过程中，非离子聚丙烯酰胺能够提高煤粉的回收率和过滤速度。在金属冶炼过程中，浮选和冶炼后的沥液和残渣中加入非离子聚丙烯酰胺ＮＰＡＭ，提高金属分离效率。
6、在磷酸提纯中, 有助于湿法磷酸工艺中石膏的分离。
7、用于以江河水源的自来水厂的水处理絮凝剂。
纺织品上浆时，如果添加一些由非离子聚丙烯酰胺配合其他药剂配置的化学浆剂，可以提高浆料的附着效果、渗透效果和脱浆性能，使纺织品的防静电性能提高，减少胶浆癍、降低上浆率。
在建筑行业，尤其是堤坝、地基、隧道灯高强度建筑建设过程中，经常采用非离子聚丙烯酰胺（95%）配合甲叉双丙烯酰胺溶液（5%）作为化学灌浆剂，起到加固混凝效果的作用。
非离子聚丙烯酰胺可以在土壤保水固沙、山坡绿化、沙土固化防尘等领域起到保湿剂的作用。
11、油田调剖堵水剂
使用非离子聚丙烯酰胺和木质纤维素配合，再加入一些其他化学助剂，可以用作油田调剖堵水剂。
What is nonionic flocculant?what is the application?
Non ion flocculant, NPAM for short, it is the linear polymer, the molecular weight is between 500-1200 million, the appearance of solid product is white powder, liquid is colorless viscous colloidal, soluble in water, hardly soluble in organic solvents. It should be dissolved at normal temperature, it easily decompose if the temperature is above 150 ℃. Belonge to Non-dangerous, non-toxic, non corrosive. Solid state PAM are hygroscopic, flocculation, adhesion, resistance reduction, thickening, and good stability.
Due to the
nonionic flocculant is without ionic functional groups, so the
PH value and salt have a little
influence to the aflocculation
performance, under acidic conditions, flocculation effect is better than
anionic flocculant, the floc strength is
stronger than anionic flocculant.
Application areas:
1,mainly used for solid-liquid seperation precess,including sedimentation,clarification,thickening,concentrationand sludge dewatering.application lines:municipal sewage,papermaking industry, food processing industry, petrochemical industry, metallurgical industry, mineral processing industry, dyeing wastewater treatment and sugar industry and various industrial wastewater treatment. If the Sewage shows acidic, we often use nonionic polyacrylamide with polyaluminium chloride and other inorganic flocculants , with fast settlement speed and good treatment effect.
2, in the paper industry can be used for paper dry strength agent, retention agent, filter aid.
3, Used in the fiber slurry (asbestos cement products) and insulating board.
4.Used for clarify agent for mine wastewater and coal washing wastewater in mining and coal industry. In the Centrifugal separation of tailings washing ,the sedimentation and filtration process of coal slime , nonionic polyacrylamide can increase coal recovery rate and filtration velocity. In metal smelting process, it can improve the separation efficiency
adding non-ionic polyacrylamide NPAM in the Leachate and residue after flotation and smelting.
5, for the treatment of dyeing wastewater, leather wastewater, oily wastewater.
6, in phosphoric acid purification, it can helps to seperate gypsum in wet phosphoric acid process.
7, for the water treatment flocculant of tap water factory
8, the textile industry additives
For textile sizing, it can improve the slurry adhesion effect , penetration effect and desizing performance if adding some chemical pulp mixed by nonionic polyacrylamide and other agent, improving antistatic performance, reducing mortar fleck, reducing sizing rate.
9, chemical grouting agent
In the construction industry, especially in the construction process of high strength building for the dam, foundation, tunnel lamp, we often use nonionic polyacrylamide (95%) with methylene bis acrylamide solution (5%) as chemical grouting agent, it can plays the role of strengthening coagulation effect.
10, soil water-keeping agent
Non ionic polyacrylamide can plays a water-keeping agent in soil water sand, green hill, the sand solidification dust and other fields
11, oil plugging agent
The non ion polyacrylamide can be used as oil plugging agent mixed with lignocellulose with adding some other chemical additives.
