装置生产操作波动或生产过程调整,会导致沥青部分指标不能满足交通部行业重交道路沥青标准或客户要求,针入度变化尤为突出。采用传统沥青调合工艺,用同一种油源生产的沥青,在罐内进行沥青调合,调合后沥青达到交通部行业重交道路沥青标准或客户要求。调合比例利用沥青调合经验公式-针入度调合计算公式进行计算。温度采用罐区沥青目前存储温度,混合方式利用沥青罐体本身的机械搅拌和循环回流混合。应用结果:在生产中,利用针入度调合计算公式计算调合比例,按照计算调合比例进行实际调合,针入度检测值与理论计算值偏离较小,调合后沥青质量满足要求。
The fluctuation of production operation or the adjustment of production process will lead to some indexes of asphalt can not meet the asphalt standard or customer requirements of heavy traffic road of the Ministry of Communications, and the changes of penetration are particularly prominent. The traditional asphalt mixing process, with the same source of asphalt produced in the tank for asphalt blending, blending asphalt to the Ministry of Communications industry asphalt pavement standards or customer requirements. Mixing ratio using asphalt blending experience formula - needle penetration adjustment calculation formula. The temperature is based on the current storage temperature of the tank area asphalt, and the mixing mode uses the mechanical mixing and circulating reflux mixing of the asphalt tank itself. Application results: In the production, the blending ratio is calculated by the formula of penetration adjustment, and the actual blending is calculated according to the blending ratio. The deviated detection value of the penetration is less than the theoretical value, and the asphalt quality meets the requirements .
