矿泥具有很大的表面积。一块每边长1公分的立方体(表面积6平方公分),能分成10亿个每边长0.001公分(10μ)的小立方体,其总表面积竟增达6000平方公分。当这些矿泥达到胶体分散程度时,其危害程度更大。虽然这种表面不均衡力的作用,可以使颗粒在彼此相遇时凝结形成较大的粒子,其危害性应显著减小,但是,由于下列两个原因就妨碍了矿泥间的彼此凝结:(一)具有胶粒分散状态的矿泥常常带有电荷,在一种溶液里带有同样的电荷,使颗粒之间
Mud has a large surface area. A cube of 1 cm long on each side (surface area 6 cm 2) can be divided into 1 billion small cubes of 0.001 cm (10 μ) on each side and its total surface area has increased by up to 6,000 cm 2. When these slimes reach the degree of colloidal dispersion, the degree of harm is greater. Although this surface imbalance can cause the particles to coalesce to form larger particles when they meet each other, their hazard should be significantly reduced, however, preventing the mud from condensing with one another for the following two reasons: A) Slimes with colloidal dispersion are often charged, with the same charge in one solution, so that between particles
