vega56降压:白云岩

                                                                           

白云岩经适当煅烧后，可加工制成白云灰，它具洁白、强粘着力、凝固力及良好的耐火、隔热性能，适于做内外墙涂料。                                                                                                                                                          

白云岩在冶金工业中主要用做熔剂、耐火材料、提炼金属镁和镁化物。                                                                                                                                  

白云岩的主要用途白云石广泛用于建材、陶瓷、焊接、橡胶、造纸、塑料等工业中。另外在农业、环保、节能、药用及保健等领域也得到了应用。                                                                                                        

矿石一般呈细粒或中粒结构,呈层状、块状、角砾状或砾状构造。白云石属三方晶系，晶体常呈马鞍状菱面体,集合体常为粒状或块状。颜色为无色、白色或浅褐至深褐色。玻璃光泽。                                                                                           白云岩是一种以白云石为主要矿物组分的碳酸盐岩，颜色为灰白色、浅灰白色。常混入方解石、黏土矿物、菱镁矿、石膏等杂质                                                                                                                              

白云岩，是一种沉积碳酸盐岩。主要由白云石组成，常混入石英、长石、方解石和粘土矿物。呈灰白色，性脆，硬度小，用铁器易划出擦痕。
