设计简介
[摘要] 酚醛树脂有良好的力学性能和耐热性能，尤其具有突出耐瞬时高温烧蚀性能。利用复合材料制作的桥塞卡瓦代替铸铁卡瓦，其独特的材料主要由玻璃纤维和环氧树脂粘合而成，提高了桥塞的可钻性和耐蚀性，延长使用寿命，节省钻铣和打捞时间。制造卡瓦时采用现代模具加工技术，选用压模成型。在卡瓦本体固化成型之前压入牙齿，解决了以前预留孔与卡瓦连接的困难，实现卡瓦的批量生产。研究难点在于牙齿为是陶瓷材料，而压入时，陶瓷的强度不够，须用玻璃纤维增强的酚醛树脂在外面包裹一层，以使牙齿达到强度要求，如何包上树脂重点。这里在牙齿外面套上一层树脂环，采用物理固定的方法，加上合适的工艺，能将复合材料的桥塞卡瓦增强提高很多，实现70MPa压差的复合材料。

[Abstract]: Phenolic resin has good mechanical properties and heat resistance，especially, the outstanding resistance to high temperature ablation. The bridge plug slip by composite materials instead of cast iron，its unique material is mainly composed of glass fiber and epoxy resin adhesive. Improve the bridge plug can be drilled and corrosion resistance，increase of service life of slip，Saving drilling and milling and fishing time. Manufacturing the slips by modern mold processing technology, selection of compression molding .Press in the teeth in compression molding before slip body curing, solved the difficulties reserving of hole and slip connection previously,realization of slip mass production. Study on the difficulty lies in the teeth as ceramic materials, and indentation, ceramic strength is not enough, must be phenolic resin reinforced with glass fiber coated with a layer of outside, so that the teeth meet strength requirements, how to package resin key. Here in the teeth are covered by a layer of resin ring, using the method of physical fixed, plus the appropriate process, the bridge plug slip by the composites improve a lot, may realize composite 70MPa differential pressure.
