Nickel Alloy Sintered Metal Filter Elements Quick Heat Transfer Accurate Filtration

• Product introduction

The sintered metal powder filter element USES metal powder as the raw material, does not need to add adhesive. After cold isostatic pressure molding, by high-temperature vacuum sintering.The pore size and distribution of metal powder can be adjusted by selecting particle size and process parameters.According to the characteristics of pore structure, material composition and compressive strength of different filtration materials, filtration products that are finally suitable for users are developed.

Sintered metal powder filter precision filtration, which can realize the micron grade can be a solid impurity in the separation of liquid, gas when the fluid passes through a certain accuracy of filter, the impurity is blocked in the surface of the filter cake formation, pure fluid through the filter, the contaminated or clean fluid containing impurities to the normal production of the required state, to ensure the purity of the product or of the downstream device protection equipment to work normally.

Different from the non-metallic sintered filter element, when the filter cake on the surface of the sintered metal powder filter element reaches a certain thickness, the filter element can be cleaned by backwashing or back blowing under certain reverse pressure due to its high strength.

Nickel sintered porous material is made of spherical pure nickel powder by pressing molding and sintering.
