商丘夏邑县虞城美孚导轨油-润滑脂1号销售吧黄油分1#、2#、3#,分级不一样,粘度也不一样(俗称软硬度不同),号数越大,粘度越大。 使用温度范围也是必看的一项,因为机械的润滑部位在摩擦作用下,会产生比较高的温度,而选用的黄油如果不支持高温下的性能,Butter is divided into 1 #, 2 #, and 3 #, with different grades and viscosities (commonly known as different softness and hardness). The larger the number, the higher the viscosity. The temperature range of use is also a must see, because the lubrication parts of the machinery will generate relatively high temperatures under friction, and if the selected butter does not support performance at high temperatures
