离心玻璃棉离心玻璃棉产品简介　　玻璃棉属于玻璃纤维中的一个类别，是一种人造无机纤维。采用石英砂、石灰石、白云石等天然矿石为主要原料，配合一些纯碱、硼砂等化工原料熔成玻璃。在融化状态下，借助外力，吹制式甩成絮状细纤维，纤维和纤维之间为立体交叉，互相缠绕在一起，呈现出许多细小的间隙。这种间隙可看作孔隙。因此，玻璃棉可视为多孔材料，具有良好的绝热吸声性能。Introduction to centrifugal glass wool productsGlass wool is a kind of glass fiber and a kind of artificial inorganic wool. Adopting such natural ores as quartz sand, limestone, the main ingredients and then coordinating with some chemical materials such as soda ash and borax, etc, the glass is hence melted. Under the melting condition, floccular fibril is made via external force and blow.The fly-over crossing is taken on between fibers and then they are intertwined . Thus many fine gaps are showed out. These gaps can be regarded as pore spaces. Therefore,the glass wool can be taken on as porous material with excellent thermal insulation and sound absorption performance.项目Item单位Unit指标Index实测值The measured figure备注Remarks容重Volume weightkg/m310-9610-96GB/T13350-2000纤维平均直径***erage fiber diameterµm＜8.04.0-6.0GB/T13350-2000憎水率Hydrophobic%＞98＞98.5JISA9512-2000导热系数Heat conduct coefficientW/m.K0.049-0.0420.045-0.032GB/T13350-2000不燃性Incombustibility不燃Incombustible合格（***）Qualified(Grade A)GB/T13350-2000吸声系数Heat absorption coefficient1.03产品混响定法1.03 product reverberation method 24kg/m32000HZGB/J47-83***高使用温度Highest usage temperature℃400410GB/T13350-2000离心玻璃棉工艺流程　　离心甩丝法生产玻璃棉的主要生产工艺是：将各种原材料按一定比例配成的混合料在熔窑中熔化成玻璃液，玻璃液经由前炉铂金漏板形成稳定的液流，再流经纺丝机到达侧壁有小孔的高速旋转的离心器里。在离心力的作用下，玻璃液被甩成一次纤维。其后，在高速喷出的混合气体作用下，一次纤维被牵拉成玻璃纤维，玻璃纤维在降落集棉网带的同时，喷洒粘结剂，再经压实、固化、横切、纵切形成一定规格的产品，***后压缩捆包、装箱包装后入库。Process flow of centrifugal glass woolThe main production technology of centrifugal silk throwing method of manufacturing glass wool is :melt mixing materials made of all kinds raw materials according to a certain proportion in the melting vault into glass liquid.The glass liquid forms a steady liquid stream through the foil leaking plate of the front furnace and then flows through the filature machine to arrive at high speed revolutionary centrifugal machine with ***all pores on the side wall. Under the function of centrifugal force, the glass fiber is falling to the wool coollection reticules ,spray the adhesive and then compaction, solidification, cross cutting and score cutting to form products of a certain gauge. Concentrate and score cutting to form products of a certain gauge. Concentrate and packaging at last and then put into storage after boxing package.
