非离子聚丙烯酰胺

/>非离子聚丙烯酰胺(npam)是丙烯酰胺单体的均聚物、是具有高分子量的低离子度的线性高聚物。由于其具有特殊的基团,便赋予它具有絮凝、分散、增稠、粘结、成膜、凝胶、稳定胶体的作用。非离子聚丙烯酰胺按分子量的大小可分为超高相对分子量聚丙烯酰胺、高相对分子量聚丙烯酰胺、中相对分子量聚丙烯酰胺和低相对分子量聚丙烯酰胺。超高相对分子量聚丙烯酰胺主要用于油田的三次采油，高相对分子量聚丙烯酰胺主要用做絮凝剂，中相对分子量聚丙烯酰胺主要用做纸张的干强剂，低相对分子量聚丙烯酰胺主要用做分散剂。(一）非离子聚丙烯酰胺(npam)技术指标：外观: 白色颗粒或粉末分子量: 数十至2000万(二）非离子聚丙烯酰胺(npam)产品用途：1、用于污水处理，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。这时pam起吸附架桥作用，使悬浮物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：聚合氯化铝、聚合氯化铝铁、碱式氯化铝、聚合硫酸铁等配合使用，在水处理中效果最佳。2、纺织工业助剂，一般适用于非离子聚丙烯酰胺(npam)为好，添加一些化学品可配成化学浆料，用于纺织品上浆。3、防沙固沙，将非离子聚丙烯酰胺溶(npam)成0.3浓度加入交联剂，喷撒在沙漠上可起到沙固的作用4、油田调剖水剂，非离子聚丙烯酰胺(npam)和木质纤维素配合，加入一定的化学助剂，广泛用作油田调剖堵水剂5、化学灌浆剂，用9.5份非离子聚丙烯酰胺(npam)加上0.5份n，n--甲叉双丙烯酰胺混溶可作为堤坝、地基、隧道等堵水的化学灌浆剂6、采矿工业中, 通常使用大量的水, 最后常须回收水中有用固体物, 并将废水净化回收用。应用非离子聚丙烯酰胺(npam)絮凝剂,可促进固体的下沉, 从而可提高生产效率, 减少尾矿流失和水的消耗, 降低设备投资和加工成本, 并免除环境污染。 7、在洗煤过程中,煤粉及煤泥的沉淀和过滤是主要的经济问题和污染控制问题。非离子聚丙烯酰胺(npam)系列产品可以减少泥土着色、管路堵塞、泵的维修以及河水污染,提高生产能力,回收煤粉和提高过滤速率, 还可以使水彻底澄清。 8、在电解精炼工艺中, 可使金属沉淀匀化, 使镀层更加光亮,提高电流效率。 9、在无机纤维泥浆(石棉-水泥制品)中可使成型的石棉-水泥制品排水性得到改善, 使石棉板坯料的强度提高; 在绝缘板中,可提高添加剂和纤维的结合能力。 10、可作保鲜膜和农用薄膜的添加剂。11、非离子聚丙烯酰胺(npam)的复合材料可作矿床、池塘、水坝、地基的灌浆材料。 12、在土壤改良中可以增强土壤团粒结构的坚固性,增加土壤的含水量及土壤结构的承载负荷。 13、非离子聚丙烯酰胺（npam）凝胶可用来分离保持生物活性的物质,药物的控制释放和酶的包埋、蛋白质电泳、电池的凝胶电解液。 (三）注意事项：1.离子型pam是通过其高分子的长链把污水中的许多细小颗粒或油珠吸附后缠在一起而形成架桥。它是一种絮凝能力非常强的絮凝剂，它的絮凝速度比阴离子型pam快。在油田含油污水处理时，通常与铝盐配合使用。2.使用前要通过实验确定其最佳用量，用量过低，不起作用，用量过高，反而起反作用。这是因为超过一定浓度，pam不但不起絮凝作用，反而起分散稳定作用。3.加药时应使用较低的浓度，以保证混合均匀。 nonionic polyacrylamide (npam) is acrylamidemonomer norbornene-type homopolymers, is both with high molecularweight low ionic degrees linear polymer. since it has specialgroups, and endow it with flocculation and dispersion, thickening,bond, film, gel, stable colloid role. nonionic polyacrylamide pressthe size of ultra-high molecular weight can be divided intorelative molecular polyacrylamide, high relative molecularpolyacrylamide, in relative molecular polyacrylamide and lowrelative molecular polyacrylamide. high relative molecularpolyacrylamide is mainly used in oil field eor, high relativemolecular polyacrylamide which is mainly used as the flocculant inrelative molecular polyacrylamide, mainly used as dry strengthagent, the paper low relative molecular polyacrylamide which ismainly used as the dispersant. (a) the ion polyacrylamide (npam)technical index: appearance: white particles or powder molecularweight: dozens to 20 million (2) nonionic polyacrylamide (npam)product use: 1, used for sewage treatment, when suspended sexsewage show acidic when used for non ionic polyacrylamideflocculant relatively appropriate. then pam up adsorption effect,make the bridge suspended particles produce flocculationprecipitation, achieve the purpose of sewage treatment. can also beused to tap water purification, especially and inorganicflocculants: polymerization alc13, polymerization alc13 iron,alkali type alc13, such as polyferric sulphate were used togetherin water treatment, the best effect. 2, textile auxiliaries,generally applied in nonionic polyacrylamide (npam) for good, toadd some chemicals can match for textile, chemical paste into thesizing. 3, preventing sand-fixation, will nonionic polyacrylamidedissolve (npam) into 0.3 concentration join crosslinking agent,spray and on the desert can have the role of sand fixation 4,oilfield, nonionic up of profile control agent polyacrylamide(npam) and lignocellulose cooperate, add certain chemical agents,widely used for oilfield profile plugging agent tone 5, chemicalgrouting agent, with 9.5 copies of nonionic polyacrylamide (npam)plus 0.5 a n, n - a fork double acrylamide immiscible can be usedas dams, foundation and tunnels of water chemical grouting agent 6,mining industry, often use a lot of water, finally often must bereclaimed water useful, and solid content with purified recyclewastewater. application nonionic polyacrylamide (npam) flocculatingagent, can promote solid sinking, thus, can improve the productionefficiency, reduce the consumption of tailings erosion and water,reducing equipment investment and processing costs, and is exemptfrom environmental pollution. 7, in coal preparation process, coaland coal slime precipitation and filter is the main economicproblems and pollution control problem. nonionic polyacrylamide(npam) series of product can reduce dirt shader, pipeline jams,pump maintenance and water pollution, improve the productionability, recycling pulverized coal and improving filtration rate,still can make water thoroughly clarification. 8, in electrolyticrefining process, can make the metal precipitation smoothingdeposit more light, improve the current efficiency. 9, in inorganicfibers mud (asbestos - cement products) can make the molding ofasbestos - cement products water drainage properties improves, makethe intensity of the slab material asbestos increased; ininsulating board, can improve the additive and fiber combinationability. 10 for film and agricultural film additives. 11, nonionicpolyacrylamide (npam) composite can make deposits, ponds, dams,foundation of grouting material. 12, in soil improvement canstrengthen the soil aggregate structure in the sturdiness, increasethe soil water and soil structure of the bearing load. 13, nonionicpolyacrylamide (npam) gel can be used to keep the biologicalactivity material separation controlled release of drugs, andenzymes embedding, protein electrophoresis, battery gelelectrolyte. (3) note: 1. ionic pam is through its polymer longchains of many of the sewage tiny particles or oil bead adsorptionformed clung together after the bridge. it is a kind offlocculating ability is very strong, the flocculant faster than itsflocculation. pam fast anionic type oily wastewater treatment inoilfield, normally used together with aluminum salt. 2. use beforeto determine the optimal dosage through experiments, dosage is toolow, it doesn't work, the dosage is too high, but the backlash.this is because more than a specified concentration, pam not onlydoesn't flocculation effect since stabilized, instead of scattered.3. dosing should be used when the lower concentration, to ensurethat the mixing.
