Description
Technical Field
The invention relates to the technical field of processing of an explosion-proof membrane, in particular to an explosion-proof membrane and a method for lightening rain drops on the membrane surface of the explosion-proof membrane.
Background
Because the hardness of the explosion-proof film base material is lower than that of the guide roller, when the speed of the explosion-proof film base material is not completely consistent with the rotating speed of the guide roller and a speed difference is formed, fine scratches caused by friction between the guide roller and the explosion-proof film base material can be generated. In general, both the active drive roller and the passive transition roller will have a certain surface roughness in order to ensure consistent movement with the rupture membrane. Typically, the roller roughness Ra is 0.1 mm. However, when the driven roller bearing is heavier or the motor control of the driving roller cannot achieve extremely high precision, the speed of the film material is different from the rotating speed of the guide roller, and then rain spots distributed on the whole anti-explosion film surface are caused, wherein the rain spots on the anti-explosion film surface are visible under strong light irradiation, and the product yield is reduced due to fine scratches with the length of less than 2 mm.
