矿物纤维喷涂棉和专用喷涂胶粘剂经专用设备高速喷出，在喷头端口充分混合，以一定压力均匀喷涂在基体表面，从而形成密闭无缝的绝热吸声层。其表面平整、纤维分布均匀，无影响使用的分层、孔洞、裂缝等缺陷。

The mineral fiber spraying cotton and special spraying adhesive are sprayed at a high speed by special equipment, and are fully mixed at the nozzle port, and sprayed uniformly on the surface of the substrate under certain pressure so as to form a seamless and insulated sound absorption layer. The utility model has the advantages of smooth surface, uniform fiber distribution, no influence of delamination, holes, cracks and the like.
