摘要：【中文】本发明涉及一种碳纤维浇注型聚氨酯空心清蜡球，属于化工产品制造技术领域。其主要技术特点在将球形泡沫放入定制好的球体模具中，浇灌成碳纤维球形体，在碳纤维球形体的外围包裹一层聚氨酯。本发明结构设计合理，制造成本低，制备工艺简单，产品强度大，使用寿命长，疏通效率高，易收集。球形泡沫在高温石油环境中发生团缩现象，在碳纤维球形体内产生空腔部分，能使清蜡球漂浮于石油表面，不会出现难以打捞或者找不见的情况。 【EN】The invention relates to a carbon fiber casting type polyurethane hollow paraffin removal ball, and belongs to the technical field of chemical product manufacturing. The method is mainly technically characterized in that spherical foam is placed into a customized spherical die and poured into a carbon fiber spherical body, and a layer of polyurethane is wrapped on the periphery of the carbon fiber spherical body. The invention has the advantages of reasonable structural design, low manufacturing cost, simple preparation process, high product strength, long service life, high dredging efficiency and easy collection. The spherical foam is subjected to a cluster shrinkage phenomenon in a high-temperature petroleum environment, a cavity part is generated in the carbon fiber spherical body, so that the paraffin removal ball can float on the surface of petroleum, and the condition that the paraffin removal ball is difficult to salvage or cannot be found is avoided.
