introduction： 1．Butter the cylinder pad when installing it Some repairmen install cylinder gaskets，Likes to put a layer of butter on the cylinder pad，It is thought that this will increase the tightness of the engine。Hardly realize，This is not only unhelpful，Rather harmful。As everyone knows，The cylinder pad is an important sealing material between the cylinder block and the head of the automobile engine，It not only requires strict sealing of the high temperature and high pressure gas produced in the cylinder，And must be sealed through the cylinder head and cylinder block with a certain pressure and flow rate of cooling water and oil，Therefore, it is required to remove and install the cylinder pad，Pay special attention to its sealing quality。 If in the cylinder pad

introduction： High shear dispersion emulsification is the distribution of one or more phases into another continuous phase，And under normal circumstances，The two phases are not mutually soluble。 Due to the relative high-speed rotation of the stator and the strong kinetic energy brought by the high-frequency mechanical effect of the stator, the materials of different properties are subjected to hundreds of thousands of instantaneous hydraulic shear in the narrow gap of the stator、Liquid layer friction、The combined effect of tear collision and surge flow centrifugal extrusion，Make sure the material is fully dispersed and emulsified、homogeneity、liquor，Thus making insoluble solid phase、Liquid phase、The gas phase is instantly highly dispersed and refined。 At the same time，Phase edge
