| 木质素纤维对防止涂层开裂、提高保水性、提高生产的稳定性和施工的合宜性、增加强度、增强对表面的附着力等有良好的效果。广泛用于沥青道路、混凝土等领域，维修道路上更是经常使用。 Lignin fiber coating to prevent crack and improve the water retention and improve the stability of the production and construction of conformance, increase strength, strengthen adhesion to surfaces has a good effect. It is widely used in areas such as asphalt road and concrete, and is often used on maintenance roads. 那么下面就简要介绍木质素纤维有什么作用，是如何表现的。 So here's how the lignin fiber works, how it works. 1.稳定作用，木质素吸纳为能够使沥青膜处于比较稳定的状态，尤其是在夏天的高温季节。当沥青受热膨胀的时候，纤维内部的空隙将会成为一种缓冲，不至于使沥青泛油，对于沥青的高温稳定性也大有裨益。 Stabilizing, lignin induces a stable condition for the asphalt membrane, especially during the hot summer season. When the expansion of the asphalt heating, fiber internal gap will become a kind of buffer, asphalt oil, not for the high temperature stability of asphalt. 2.增稠作用，可以提高路面的粘结能力，增加沥青与矿料之间的粘附性，通过油膜的粘结可以提高材料之间的粘结力。 2. The thickening effect, can improve the bonding capacity of pavement, increase the adhesion between asphalt and ore material, through the oil film adhesive can improve the cohesive force between the materials. 3.加筋作用，在SMA混合料中加入一定的木质素纤维，使纤维在混合料中以一种三维的分散状态存在，就像土工栅栏、各种钢纤维混凝土、土工布等加筋材料一样，起到加筋的作用，使路面更加结实稳固。 3. The reinforcement effect, add certain lignin fiber in SMA mixture, the fibers in the mixture in a three dimensional existence of decentralized state, like the geotechnical fence, all kinds of steel fiber reinforced concrete, the geotextile reinforced material, have the effect of reinforcement, make the road more strong solid. 4.分散作用，如果没有木质素，用量大的沥青矿粉很有可能变成胶团，木质素可以使结团的胶团分散，如果不能够均匀的分散，就会在路面上清楚的看见“油斑”的存在。 4. The dispersion effect, if there is no lignin, the dosage of asphalt kuangfen is likely to become micelle, lignin can scatter the cluster of micelle, if can't evenly dispersed, can clearly see on the road "oil spot" exists. |
