Epoxy resin-modified cement binder composition as a coating or seal
A) at least one epoxy resin, binder (A); B) containing a water at least one amine compound as amine curing agent, an aqueous curing agent (B); C) at least one water including hydraulic inorganic binder, preferably cement, a multi-composition comprising a solid agent (C), based on the total weight, it contains at least 8% by weight of an organic binder, the organic binder , and from the total amount of epoxy resin and amine curing agent, multidrug composition is disclosed. The multi-composition preferably comprises at least one pigment as a colorant. The multi-agent composition has excellent compatibility to the floor coating or sealing, which can be prepared in a variety of colors.
Performance of metal gasket influenced by the final design of the forming result. Good shape of the gasket will give optimal leakage performance. It is difficult to produce good shape because of the spring back effect. In this study, we investigated the forming process of metal gasket 400MPa-mode for two types of dies which are open dies and closed dies. The finite element method employed to analyze the effect of different types of dies on the final design of the corrugated metal gasket. The simulation shows corrugated metal gasket 400MPa-mode with closed dies result in better final shape than open dies.
