If the machinery, equipment and vehicles used under different conditions are connected with screw locks, their loosening is generally caused by vibration and mechanical wear. The usual spring washer, flat washer, lock nut and other thread fastening methods can only ensure that the contact area between the thread and the thread is less than 25, and this product can ensure the meshing contact, so that the locking effect is greatly improved. The locking effect of Fengshen anaerobic glue (anoxic glue) 271 is shown in the following table. M10 fine thread is used in the table, and the vibration condition of pre-tightening torque 290N.CM is 2 mm; Sine wave; The frequency is 50 cycles per second; Acceleration 98.07M/S 2.
Fastener locking and sealing is the application field of hypoxic rubber, but also the main use of hypoxic rubber. After the glue is filled with all the gaps at the mesh of the thread, it is solidified due to hypoxia, forming an insoluble and insoluble polymer that fills the entire thread gap, making it difficult for the contact part of the thread to produce relative displacement, which can prevent micro-slip and loosening under the action of external force. The bonding strength of the glue increases the loosening torque and prevents the thread from loosening. The adhesive layer has good vibration absorption, anti-loosening and sealing performance. This locking and sealing method is not only simple but also more reliable than commonly used mechanical methods (such as spring pads, double nuts, etc.). In addition, it can simplify the process and improve the efficiency, such as the engine cylinder block with many bolts, in order to ensure the lock and seal, often need to be processed into blind holes, more difficult. If Feng Shen 271 is used, it can be changed to through hole without worrying about leakage.
