农机胶粘剂具有固化速度快,粘接工艺简便,无需特殊的加热和固化设备,粘接强度高、密封性好,耐油、耐水、耐一般化学药品等特点。其粘接强度:常温下,钢-钢抗剪强度为200公斤/厘米~2,铝-铝抗剪强度为160～180公斤/厘米~2,能适用于工作温度120℃以下的机件。物体胶接后,在室温25℃时经2～3小时后,便可达到比较高的粘接强度,如加热至60℃时,1小时即可达到最高粘接强度。工件在涂敷涂层之前,需喷砂或用砂轮、钢丝刷、砂布等除锈,直至露出金属的本色,
Agricultural machinery adhesive with fast curing, bonding process is simple, without special heating and curing equipment, high bonding strength, good sealing, oil, water, chemicals and other general resistance characteristics. The bonding strength: at room temperature, steel - steel shear strength of 200 kg / cm ~ 2, aluminum - aluminum shear strength of 160 to 180 kg / cm ~ 2, can be applied to the working temperature below 120 ℃ parts. Object bonding, at room temperature 25 ℃ after 2 to 3 hours, you can reach a higher bonding strength, such as heating to 60 ℃, 1 hour to reach the highest bonding strength. The workpiece before coating, sandblasting or grinding wheel, wire brush, emery cloth and other rust, until exposed the true nature of the metal,
