METHOD FOR MANUFACTURING PLATING PRESSURE-FREE STEEL SHEET IN PERPENDICULAR ELECTRIC GALVANIZED EQUIPMENT

摘要

A gasket is described. The gasket comprises a sealing layer and a support layer. The sealing layer is formed from a resilient material which comprises a CEV component in a proportion of at least 25 % w/w of the sealing layer. The CEV component is at least partially derived from dry CEV. A hydrolysis resistant polymer to improve the water resistance of the sealing layer is also provided in the proportion of less than 20 % w/w of the sealing layer. Generally, the level of CEV falls within the range 25-80 % w/w of the sealing layer. A method of producing a gasket is also described. The method involves applying a wet sealing layer dough to a support material, and drying the wet sealing layer dough on the support material. The solids content of the wet sealing layer dough prior to the drying step is in the range 30-80 % w/w of the dough material.
