| 泵力循环搅拌法。按规定的掺配比例计算出所需的用量，投入甲沥青贮罐内处于热熔状态的沥青中，开动沥青泵将甲贮罐中的沥青与混合液泵入空置的乙沥青贮罐中，再将乙沥青贮罐内的沥青与混合液泵回甲沥青贮罐，这样反复泵拌4～5次，抗剥落剂供应，则就可以均匀分布于沥青中。 Pump force circulation stirring method. Calculate the required amount according to the specified mixing proportion, put the asphalt in the hot-melt state in the asphalt storage tank of a, start the asphalt pump to pump the asphalt and mixture in the tank of a into the empty asphalt storage tank, and then pump the asphalt and mixture in the tank back to the asphalt storage tank of a, so that the asphalt and mixture can be evenly distributed in the asphalt storage tank after 4-5 times of pump mixing and anti stripping agent supply Medium. 密度应与沥青密度相当或接近，抗剥落剂厂家，PH值宜gt;7，以常温下液态为宜，凝固点lt;0℃。一般对眼、呼吸道及皮肤有轻微刺激，使用中如遇不适可暂时离开现场，呼吸新鲜空气。 The density should be the same as or close to the asphalt density, the anti stripping agent manufacturer, the pH value should be gt; 7, the liquid at room temperature is suitable, the freezing point is lt; 0 ℃. Generally, it has slight irritation to eyes, respiratory tract and skin. If you feel uncomfortable during use, you can leave the site temporarily to breathe fresh air. 沥青与沥青抗剥落剂的混合液在静置不用的状态下，沥青抗剥落剂，不宜超过24小时，否则应按上述程序重复搅拌一次。溶于沥青中超过72小时，抗剥落剂，应对其路用性能重新进行评价，必要时再适量加入后重新调匀。 When the mixture of asphalt and asphalt anti stripping agent is not used in the static state, the asphalt anti stripping agent shall not be more than 24 hours, otherwise, it shall be mixed again according to the above procedures. After dissolving in asphalt for more than 72 hours, the anti stripping agent shall be re evaluated for its road performance, and if necessary, it shall be added properly and re mixed. |
