由于环氧树脂在远红外区有很宽的吸收带,用远红外加热环氧树脂可加快固化速度,并能提高与铝合金粘结力和浇注体的强度,我们用于修补挖掘机用柴油机气缸,效果较好。一、缸体腐蚀情况腐蚀位置:1～6缸都是在发电机对面,腐蚀点距离缸体底面40～50mm之间,向上延伸,最高130mm,最低60mm。腐蚀面最宽40mm,一般为30mm。腐蚀深度1～4缸已穿孔漏水,其余为3～5mm。1～2缸腐蚀最严
As the epoxy resin in the far infrared region has a wide absorption band, with far-infrared heating epoxy resin can speed up the curing speed, and can improve the bonding strength with aluminum alloy and casting body strength, we used to repair excavator diesel engine Cylinder, the effect is better. First, the corrosion of cylinder corrosion Location: 1 to 6 are in the generator across the cylinder, the corrosion point from the bottom of the cylinder 40 ~ 50mm, extending upward, the highest 130mm, the lowest 60mm. Corrosion surface is the widest 40mm, usually 30mm. Corrosion depth of 1 to 4 has been punctured water leakage, the remaining 3 ~ 5mm. 1 to 2 cylinder corrosion the most stringent
