研究结果表明:防热涂料的剪切强度分散性较大,这主要是由于溢胶现象使得搭接长度的准确测量比较困难,同时造成了试件的对中性较差。另外,胶层厚度的不均匀也是造成了数据分散的原因之一。 The results show that the shear strength of the heat-resistant coating is more dispersive, which is mainly due to the over-glue phenomenon, which makes it difficult to accurately measure the lap length, and at the same time causes the test piece to have poor neutrality. In addition, the non-uniform thickness of the adhesive layer is also one of the reasons that data is scattered.
