微磁聚凝剂简介

    微磁聚凝剂是水溶性的高分子聚合物， 主要用于各种工业废水的絮凝沉降，沉淀澄清处理，如钢铁厂废水，电镀厂废水，冶金废水，洗煤废水等污水处理、污泥脱水等。由于其分子链中含有一定数量的极性基团，它能通过吸附水中悬浮的固体粒子，使粒子间架桥或通过电荷中和使粒子凝聚形成大的絮凝物，故可加速悬浮液中粒子的沉降，有非常明显的加快溶液澄清，促进过滤等效果。

微磁聚凝剂由于它具有：

1、澄清净化作用；

2、沉降促进作用； 

3、过滤促进作用；

4、增稠作用及其它作用。

   在废液处理、污泥浓缩脱水、选矿、洗煤、造纸等方面，能够充分满足各种领域的要求。

   煤厂对煤泥水的处理一般情况下采用“旋流器-浓缩机-压滤机（煤泥沉淀池）”处理工艺。一般情况下都是采购机高分子絮凝剂。高分子絮凝剂与煤泥微粒或煤泥胶体接触作用，中和了煤泥表面的电性，降低表面能，使煤泥微粒凝聚沉淀。不同粒度组成的煤泥水要选用不同分子量的絮凝剂。在使用微磁聚凝剂进行水处理的时候，要保证类型与煤泥水的pH值相吻合，微磁聚凝剂的适于偏碱性煤泥水。

The particle aggregate of iron powder(iron dust) is smaller than that of 1mm. Color: black. It is the main rawmaterial of powder metallurgy. According to the granularity, the habit ispided into five grades: coarse powder, medium powder, fine powder andultrafine powder. The iron powder with the particle size of 150 μ m is coarsepowder, the iron powder with the particle size of 44 ~ 150 μ m is 1044 μ m andthe ultrafine powder is less than 0.5 μ m. Generally, the powder which can pass325mesh standard sieve, that is, the powder with particle size less than 44 μm, can be called subsieve powder. If more accurate sieving is to be carried out,the air flow classifier can only be used, but for some easily oxidized ironpowder, it can only be made by JZDF nitrogen protection classifier. Iron powdermainly includes reduced iron powder and atomized iron powder, which are namedafter different modes of production. The application of iron powder in industryis mainly used to produce powder metallurgy mechanical parts, the main physicalproperties of which are loose density, fluidity, formability, particle shapeand so on. These properties are mainly affected by the production method ofiron powder and its chemical composition. (1) Application of hinged Powder inthe manufacture of Powder metallurgical structural parts the manufacture ofmechanical parts by powder metallurgy has the advantages of saving material andworking hours, being easy to automate, and easy to organize mass production,which has attracted widespread attention. Has developed rapidly. Iron basedpowder metallurgy mechanical parts have been widely used in China's automobile,motorcycle, household appliances, electric tools, office machinery,agricultural machinery, machine tools, instruments, textile machinery,metallurgical machinery and other industrial sectors. Good technical andeconomic benefits have been obtained. According to incomplete statistics, theproduction of iron powder in China has exceeded 100000 tons in 2003, whichindicates that iron powder has become a kind of important metal raw material inmechanical manufacturing industry. (2) the application of iron powder in theproduction of electrode, flame cutting and so on. Iron powder used in weldingrod occupies a certain proportion of the total application of iron powder(Sweden accounts for 37%), Generally, adding 10% iron powder to the coating ofthe electrode can improve the welding performance of the electrode. Flamecutting and cleaning is another important aspect of iron powder application.The United States uses about 7000 tons of iron powder a year for this purpose.When cutting refractories (such as concrete) with hydrogen oxygen flame oracetylene flame, adding iron powder to the flame can increase the flametemperature and also play the role of solvent.
