Embodiment

[0012] A gasket for a hydrogen peroxide heat exchanger, which is used on the side of the hydrogen peroxide medium and the side of the circulating water medium. The innovation is that the gasket used on the side of the hydrogen peroxide medium is made of VITON rubber material, which can withstand high temperature and chemical corrosion of hydrogen peroxide. , In addition, the service temperature range of the gasket is -20°C to 260°C, so it has a wide application range, and the fluorine content in the VITON rubber material used is 68-69wt%. The gasket on the side of the circulating water medium is made of EPDM rubber material.

[0013] Because hydrogen peroxide is corrosive to a certain extent, another rubber-like VITON gasket is selected on the hydrogen peroxide side. The advantage is that this gasket is elastic and resistant to high temperature and chemical corrosion of hydrogen peroxide. Checked out after a year of use and it works great.

Abstract

The invention relates to a gasket used for a hydrogen peroxide heat exchanger; the gasket used for the hydrogen peroxide heat exchanger is used for a hydrogen peroxide medium side and a circulating water medium side, wherein the gasket used for the hydrogen peroxide medium side is made of a VITON rubber material, and the gasket used for the circulating water medium side is made of an EPDM (ethylene-propylene-diene monomer) rubber material. Compared with the prior art, the gasket made of the VITON rubber material is selected at the hydrogen peroxide medium side, and the gasket is elastic, and can resist high temperature, and the chemical corrosion of hydrogen peroxide, and has a very good effect through inspection after used for one year.

Description

technical field [0001] The invention relates to a gasket, in particular to a gasket for a hydrogen peroxide heat exchanger. Background technique [0002] The existing hydrogen peroxide heat exchanger adopts stainless steel cooling fins (304L), the media on both sides are circulating water and hydrogen peroxide, and the gaskets used are general-purpose rubber EPDM. However, this type of gasket can be used on the circulating water side, but it is not suitable for hydrogen peroxide. After the heat exchanger was used frequently for a period of time, leakage occurred. After tightening the pressure plate bolts of the heat exchanger many times, and increasing the pre-tightening force of the bolts, it was ineffective. After disassembly, it was found that the gasket was seriously aged and had already lost its original elasticity. This has a certain impact on the continuity of production. Contents of the invention [0003] The purpose of the present invention is exactly to provide...
