LCD display module oil machineWolfram disulfide (WS2) is a jellied lubricator with a lamellar artefact similar to MoS2. He also correlated the tribological properties to the axial ratio c0/na0, which moldiness surpass 1.87 to make a low conflict coefficient. This ratio equals 1.95 for 2H–MoS2 and 1.96 for 2H–WS2. In Illustration 14.1, the eleme
