Ceramic grain filters ard made of refined pottery clays added with certain modifiers, and processed of grinding, mixing, shaping and high temperature sintering. they do not contain any substances that harmful to people or environment. they are hard and rough in surface, porous inside the structure, and have the advantages of high mechanical strength, large specific surface area and porosity. when used in water treatment, they behave a activated surface property, a great amount of pollutant entrapment, less water head loss in the filter bed, lower consumption of back - flush water, stable in chemical and gbiologic property, and long service life, ceramic grain filters is a new and efficient filter material to increase the water yield, upgrade the water quality, and save chemicals and energy
陶粒濾料是以精製陶土為主要原料，摻加適量改性劑，經粉碎，混練，成型和高溫煅燒而製成的，不含任何對人體和環境有害的物質.其表面堅硬，粗糙，內部疏鬆，多孔，具有機械強度高，比表面積大，孔隙率大的特性.用於水處理中，具有表面性狀好，截污能力強，過濾水頭損失小，反沖洗耗水量低，化學穩定性和生物學穩定性好，使用壽命長的特點.陶粒濾料是一種能增加水產量，提高出水質量，節省藥劑和能耗的新型高效過濾材料 -
The conclusions are as follows : ( 1 ) high - pressure water - atomization can be used to produce a pre - alloyed steel powder with high apparent density, high green strength, size - stability after sintering and low hydrogen - loss content ; ( 2 ) the higher smelting temperature and / or water pressure, the finer particle size of steel powders ; ( 3 ) when the atomization angle holds in a reasonable value ' s range the obtained powder will have a better particle size distribution ; ( 4 ) an optimum atomization technological parameters : liquid steel flux, water pressure and water prick angle was obtained ( 5 ) reduction variables ( temperature, holding time, material - bed ' s thickness and reducing gas flux ) have a significant effect on the particle agglomeration and properties of final powder was given ( 6 ) different alloying methods were developed to modify properties of ferrous powder materials and hence to broaden its applications in ferrous powder metallurgy industry
本文系統研究了水霧化預合金鋼粉生產工藝及合金化方法對鐵基粉末冶金材料性能影響，詳細研究了冶煉、霧化、還原工藝參數對預合金鋼粉化學成份和物理性能影響，並得出如下結論： （ 1 ）採用高壓水霧化技術可用於生產高密度、高強度、尺寸穩定性的低氫損含量的水霧化預合金鋼粉。 （ 2 ）冶煉溫度越高，高壓水壓力越大，所得生粉顆粒粒度越細。 （ 3 ）水錐角調整在一個適當角度范圍內可獲得粒度組成較好的生粉。 -
