Abstract

The invention provides a sealing gasket used for biochemical pharmaceutical equipment. The sealing gasket is of a multi-layer composite structure which comprises a base layer; and an expansion buffer layer, a fire-retardant layer, an anti-corrosion layer, a high-temperature-resistant layer and an outer layer are sequentially arranged on each of the front surface and the back surface of the base layer from inside to outside. The sealing gasket used for the biochemical pharmaceutical equipment has very good fire resistance, corrosion resistance and high temperature resistance, and can be widely applied to various complex biochemical equipment environments; secondly, expansion of a product is sufficiently increased by the sealing gasket, so that the product has very good mechanical strength and elasticity. Besides, the sealing gasket used for the biochemical pharmaceutical equipment provided by the invention further has certain functions of water resistance, oil resistance, dust resistance and static electricity resistance.

Description

technical field [0001] The invention relates to the field of biochemical pharmaceutical equipment, in particular to a sealing gasket used for biochemical pharmaceutical equipment. Background technique [0002] Gasket is a kind of material used for sealing inside machinery, equipment, pipelines, etc. The commonly used sealing gaskets mainly include asbestos sealing gaskets and rubber sealing gaskets from the material. [0003] Gaskets are very important in biochemical equipment. In the production process of biochemical equipment, there are often accidents such as equipment failure, production interruption, and material scrapping. The reason is that there are many factors that cause the failure of sealing technology due to damage to sealing components (including sealing gaskets). In addition to ensuring the accurate execution of process parameters in a set of biochemical equipment, sealing components (including sealing gaskets) have another function to avoid three leakages (...
