汽车发动机的气缸体在铸造、使用中,常出现砂眼或裂纹等。经过对缸体渗漏现象进行多次堵漏试验,结果表明,用堵漏剂、胶粘剂、裂纹冷焊及加热减应力等4种方法解决气缸体渗漏问题,效果好、时间快,而且成本低,工艺简单。堵漏剂法堵漏剂配方的选择和堵漏工艺的质量是提高堵漏效果的 Car engine cylinder block in the casting, use, often appear trachoma or cracks. After plugging the tank for many times, the results show that the leakage of the cylinder block can be solved by using four methods, such as plugging agent, adhesive, cold welding with heat and stress reduction by heating, and the effect is good, the time is fast, and the cost Low, simple process. Sealant method Sealant formula choice and plugging The quality of the process is to improve the plugging effect
