In addition to the selection of the type of plate heat exchanger and the material of the plate, the selection of the adhesive gaskets are also crucial, which is also called the gasket. Today you will get a quick introduction to the classification and application of plate heat exchanger gaskets.

The classification and application of the plate heat exchanger gaskets are mainly: commonly used mainly nitrile rubber, EPDM rubber, hydrogenated nitrile rubber, fluorine rubber.

1. NBR ~ 140 ?, the advantages: excellent resistance to gasoline and aliphatic hydrocarbon oils; heat resistance, gas sealing, wear resistance and water resistance are better; disadvantages: cold and ozone resistance is poor, strength and elasticity is low, acid resistance is poor, electrical insulation is not good, resistance to polar solvents is also poor. 2. EPDM EPDM ~ 180 ? advantages: excellent chemical stability (concentrated Except nitric acid), ozone resistance, excellent aging resistance, outstanding electrical insulation performance, resistance to polar solvents - ketones, esters, etc., easy to color and color stability; disadvantages: not resistant to aliphatic and aromatic hydrocarbons, poor adhesion, slow vulcanization.

3 hydrogenated nitrile rubber HNBR ~ 140 ?, maintaining the characteristics of nitrile rubber, oil resistance, heat resistance, a little better than nitrile rubber. 4. Fluorine rubber FKM ~ 180 degrees to 200 degrees. Advantages: acid and alkali resistance, excellent oil resistance, excellent radiation resistance and high vacuum performance; electrical insulation, mechanical properties, chemical corrosion resistance, ozone resistance, good atmospheric aging resistance, is a good overall performance of special synthetic rubber; disadvantages: poor processing, expensive, poor cold resistance, low elasticity and permeability.

The above is the classification and application of the plate heat exchanger gaskets are introduced, you can combine the characteristics of the four types of rubber, choose the most suitable for the site working conditions of the material. Qingdao Ripert, professional R & D and production of plate heat exchanger for 13 years, can provide the most optimal technical solutions according to your needs, welcome to consult.
