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。IntroductiontocentrifugalglasswoolproductsGlasswoolisakindofglassfiberandakindofartificialinorganicwool.Adoptingsuchnaturaloresasquartzsand,limestone,themainingredientsandthencoordinatingwithsomechemicalmaterialssuchassodaashandborax,etc,theglassishencemelted.Underthemeltingcondition,floccularfibrilismadeviaexternalforceandblow.Thefly-overcrossingistakenonbetweenfibersandthentheyareintertwined.Thusmanyfinegapsareshowedout.Thesegapscanberegardedasporespaces.Therefore,theglasswoolcanbetakenonasporousmaterialwithexcellentthermalinsulationandsoundabsorptionperformance.项目Item单位Unit指标Index实测值Themeasuredfigure备注Remarks容重Volumeweightkg/m310-9610-96GB/T13350-2000纤维平均直径***eragefiberdiameterµm＜8.04.0-6.0GB/T13350-2000憎水率Hydrophobic%＞98＞98.5JISA9512-2000导热系数HeatconductcoefficientW/m.K0.049-0.0420.045-0.032GB/T13350-2000不燃性Incombustibility不燃Incombustible合格（***）Qualified(GradeA)GB/T13350-2000吸声系数Heatabsorptioncoefficient1.03产品混响定法1.03productreverberationmethod24kg/m32000HZGB/J47-83***高使用温度Highestusagetemperature℃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。ProcessflowofcentrifugalglasswoolThemainproductiontechnologyofcentrifugalsilkthrowingmethodofmanufacturingglasswoolis:meltmixingmaterialsmadeofallkindsrawmaterialsaccordingtoacertainproportioninthemeltingvaultintoglassliquid.Theglassliquidformsasteadyliquidstreamthroughthefoilleakingplateofthefrontfurnaceandthenflowsthroughthefilaturemachinetoarriveathighspeedrevolutionarycentrifugalmachinewith***allporesonthesidewall.Underthefunctionofcentrifugalforce,theglassfiberisfallingtothewoolcoollectionreticules,spraytheadhesiveandthencompaction,solidification,crosscuttingandscorecuttingtoformproductsofacertaingauge.Concentrateandscorecuttingtoformproductsofacertaingauge.Concentrateandpackagingatlastandthenputintostorageafterboxingpackage.)
