树脂是碳(C)与碳原子保持主链构成的高分子物质,树脂有天然树脂和合成树脂。树脂有粘结性、机械强度、着色性、耐药性、柔韧性、固化时间等诸特性。实际使用的树脂是改性树脂。市场上销售的树脂为了降低价格,加进了各种添加剂。这些添加剂称为填充剂。其中有软化剂、增量材料、着色剂,稳定剂、紫外线吸收剂、难燃剂、强化材料,导电材料、消泡剂等。如果与树脂的亲和性不好,就不能使用。树脂有可能保持材料的种种特性。
Resin is carbon (C) and carbon atoms to maintain the main chain of polymer material, the resin has natural resin and synthetic resin. Resin adhesion, mechanical strength, coloring, resistance, flexibility, curing time and other characteristics. The actual resin is a modified resin. The resins sold on the market add various additives to lower the price. These additives are called fillers. Among them are softeners, extenders, colorants, stabilizers, UV absorbers, flame retardants, reinforcing materials, conductive materials, defoamers and the like. If the affinity with the resin is not good, it can not be used. It is possible for the resin to retain the characteristics of the material.
