铁粉简介
铁粉颜色呈银灰色。是粉末冶金的主要原料。按粒度，习惯上分为粗粉、中等粉、细粉、微细粉和超细粉五个等级。粒度为150～500μm范围内的颗粒组成的铁粉为粗粉，粒度在44～150μm为中等粉，10～44μm的为细粉，0.5～10μm的为极细粉，小于0.5μm的为超细粉。铁粉在粉末冶金销售中用量较大，其耗用量约占金属粉末总消耗量的85%左右，高比重铁粉还用在橡胶制品、树脂、硅胶行业配重。
铁粉的主要市场是制造机械零件，其所需铁粉量约占铁粉总产量的80%。在食品包装中放防腐剂，其主要成分是铁粉，铁粉的作用简单来说就是同时吸收水和氧气。一般干燥剂只能够吸水，铁粉颗粒非常细小的时候能迅速吸收水和氧气，这样的铁粉成为还原铁粉，为灰黑色粉末。
Iron powder silver in colour. Is the main raw material of powder metallurgy. According to the granularity, customarily divided into coarse, medium and fine powder, fine powder and ultrafine powder five grades. Granularity is 150 ~ 500 microns within the scope of the particles of iron powder as the coarse powder, grain size between 44 and 150 microns for the medium powder, 10 ~ 44 microns for fine powder, 0.5 ~ 10 microns is very fine powder, less than 0.5 microns for superfine powder. To the production of powder metallurgy iron powder dosage the biggest, its consumption accounts for about 85% of total consumption of metal powder, high ChongTie powder is used in rubber, resin, silicone industry counterweight.
Iron powder is the main market manufacturing machinery parts, the required amount of iron powder accounted for about 80% of the total iron powder production. Put preservatives in food packaging, its main component is iron powder, the effect of iron powder is simply to absorb water and oxygen at the same time. Generally desiccant can only water, iron powder particles of very small time can quickly absorb water and oxygen, iron powder be reduced iron powder, colored powder.
铁粉制作工艺
铁粉是利用氮气保护粉碎机进行氮气环境下的超微粉碎，防止氧化。使用气流粉碎的目的是能使高硬度的铁粉粉碎至微米级别，使用氮保系统来进行粉碎则是为了防止氧化和爆炸。
对于雾化法或还原法销售的铁粉，若产生假团聚则需进行打散，由于很多铁粉对打散环境要求很高，需要闭路情况进行打散或者氮气条件下打散，故一般用分级式冲击磨加氮气系统进行打散作业。由于氮气系统比较复杂，故氮气系统的打散作业对设备要求较高。
Iron powder is the use of nitrogen protection pulverizer for nitrogen environment of superfine grinding, prevent oxidation. Is the purpose of using airflow pulverization can make high hardness of iron powder grinding to micron level, use nitrogen system for crushing is to prevent oxidation and explosions.
For atomization method or the production of iron powder reduction process, if produce false reunion the need to break up, because a lot of iron powder to scatter environmental requirements is very high, need closed-circuit conditions to break up or break under the condition of nitrogen, so the classification type impact mill add nitrogen system is commonly used in scattered operations. Because the nitrogen system is more complex, so the scattered operation of equipment to demand higher nitrogen system.
铁粉用途
1.生铁粉:主要用于医药，染料，保鲜剂，脱氧剂，怀炉（暖宝宝），配重，水处理，保健品等领域，规格从20目-200目，可制定客户所需规格，含铁量***。
2.还原铁粉的主要用途有：①作为粉末冶金制品的原料，耗用量约占铁粉总耗用量的60～80％；②作为电焊条的原料，在药皮中加入10～70％铁粉可改进焊条的焊接工艺并***提高熔敷效率；③作为火焰切割的喷射剂，在切割钢制品时，向氧-乙炔焰中喷射铁粉,可改善切割性能，扩大切割钢种的范围，提高可切割厚度；④还可作为有机化学合成中的还原剂、复印机油墨载体等。
