我厂815吨锻造行车的250吨翻钢机,生产中常受到撞击,减速器紧固件容易松动、脱落,蜗轮位移,壳体受挤压变形,致使接合面间隙达2毫米左右,造成泄漏。我厂原用国产液态密封胶,因其使用温度满足不了翻钢机所经受的幅射热(200℃),密封效果一直不佳。1981年我们改用了兰州化学物理研究所研制的KL-1密封剂,它是一种高温干性附着型密封剂。工作温度-100℃直至600～800℃,分解温度1000℃以上,封严耐压性良好,平面封严,常温可达250公斤/厘米~2,100℃时可达85～40公斤/厘米~2,200℃时可达
I plant 815 tons of forging driving 250 tons of steel machine, production are often hit, reducer fasteners easily loosen, fall off, worm gear displacement, the shell by extrusion deformation, resulting in joint clearance of about 2 mm, resulting in leakage. Our factory used homemade liquid sealant, because of its use temperature can not meet the machine hit by radiant heat (200 ℃), the sealing effect has been poor. In 1981 we switched to Lanzhou Institute of Chemical Physics developed KL-1 sealant, which is a high temperature dry adhesion sealant. Operating temperature -100 ℃ up to 600 ~ 800 ℃, decomposition temperature above 1000 ℃, sealing pressure resistance is good, flat sealing, room temperature up to 250 kg / cm ~ 2, 100 ℃ up to 85 ~ 40 kg / cm ~ 2,200 ℃ Up to
