供应用于船舶防腐|内外墙乳胶|木器漆的矽比科石英粉（硅微粉）长石X7

产品功能与特性                                                                                                                            中国 优宝微长石填料是由低含量游离二氧化硅的长石精制而成，其白度自然，具有低可溶性盐的完全化学惰性。作为 经济性原料，优宝在增强各种工业以及养护涂料系统中效果显著。 优宝的颗粒坚硬有棱角，能够外在形成一层刚性网状保护膜使生产出的涂料具有抗气泡，防起霜，耐冻裂的特点。 将具有高硬度的优宝加入配方当中，可以增加涂料的耐磨性从而提高其防污以及耐候性。这些超白填料的低吸油 量能够在不影响涂料粘度的条件下提高其填充量，最小程度增加颜料的情况下提高涂料颜色强度。优宝能够增强 涂料色彩的清晰度以及*性，广泛运用于各种商业，工业，船舶涂料等领域。 优宝各规格产品之生产严格按照内部质量确认体系，以确保产品化学纯度和颗粒分布一致性达到预期要求。   粒径分析及物性 平均值，不作为产品标准                                                                          平筛分粒度                                                                   ASTM                   MICRONS                     X7                                                               100                        150                            ---                                                               200                        75                              --- 个别筛网                   325                        45                             --- 筛余百分比%                          400                        38                             0.02                                                                   20                              95.3                                                                   10                              71.6   雷射粒径分析                                                                 5                               44.5                                                                 2                               20.6 颗粒直径  (D90) m                                                                          16.2                                                          中位粒径    (D50) m                                                                        6.0                                     颗粒粒径  (D10) m                                                                          1.5                                  比表面积, Blaine (cm2/g)                        ASTM C-204                     16260                                  吸油量  (g/100g)                                  ISO 787-5 : 1980                 25                                      酸碱值  (20% slurry)                            ISO 787-9 : 1981                  10.2                                     粉末亮度  (R457nm)                           Datacolor, Microflash            90                                       松密度  (g/cm3)                                 ISO 787-11 : 1981                  0.59                                     比重  (g/cm3)                                      ASTM C-128                              2.61                                                                                              含水量%                                           (*) ASTM C-566                   0.2                        化学组成分析 平均值        重量百分比   X7   SiO2                                       68.02 AI2O3                                     19.43 K2O                                        0.07 Na2O                                     11.15 CaO                                       0.52 MgO                                      0.02 Fe2O3                                    0.04 TiO2                                       0.03 L.O.I                                       0.28 订货资讯 发货地: 中国 包装: 25公斤多层牛皮纸袋、500KG*编织袋 （特别要求） 标签：     上海市石英粉   上海市石英粉厂家
