金属粘接是一种发展迅速的新技术,已经成功地应用于航空工业,但现在也广泛应用在一般工业,特别是汽车工业.近代粘接工艺一大进步是将低分子量橡胶引入硬而脆的树脂中,发展出一种所“谓强韧胶粘剂”大大提高了接缝的抗劈裂、撕裂和冲击力的能力,同时不降低抗剪强度.而且,某些胶粘剂现在能容许粘合工作表面存在适量污物,如油脂.
Metal bonding is a rapidly developing new technology and has been successfully applied in the aviation industry but now it is also widely used in the general industry, especially in the automotive industry. A major advance in modern bonding technology is the introduction of low molecular weight rubber into hard and brittle , A “toughened adhesive” has been developed that greatly improves the ability of seams to resist splitting, tearing and impact without reducing shear strength.Moreover, some adhesives now allow adhesion Appropriate amount of dirt on the work surface, such as grease.
