ZA Swinging Fibre,abopting HP Alumina.Silica Powder,Zirconia as the material,melted by Resistance Furnace,blowing or swinging,is produced by swinging technology.

含锆型硅酸铝耐火纤维棉，以高纯氧化铝硅石粉及锆英沙合成为原料，经电阻炉熔融喷吹或甩丝成纤工艺生产而成。

Many kinds of treatment are used for fluoride removal. Conventional methods including coagulant sedimentation, active alumina adsorption, bone char adsorption are not suitable for rural areas owing to operation and management. Membrane methods for defluoridation, such as electric infiltration and reverse osmosis, have the advantage of convenient application, simple operation and good adaptability.

用于饮用水除氟的水处理技术有多种，常规除氟技术的有混凝沉淀法、活性氧化铝吸附法、骨炭吸附法，常规除氟技术由于受技术操作、管理、运行等要求影响，不宜在农村使用，膜法除氟技术，如电渗析、反渗透等应用方便，操作简单，适宜性强。

The reflective coating was prepared with glass bubbles and Al 〓 coated glass bubbles used as pigments. The naked glass bubble went together during the coating drying because its'low density. When the Al 〓 coated glass bubbles used as pigments, the bubbles can be dispersed very well in the dry coating.

空心玻璃微球和氢氧化铝涂层玻璃微球作为填料时，涂料在400nm-2500nm范围内都具有较大反射率；纳米二氧化钛作填料时，在可见光区域具有较大反射，红外区域反射率较小；以纳米二氧化硅作为填料的涂料在整个紫外-可见-近红外区域反射率都很低。
