Site£ºProducts¡úPorous Product->Introduction |
|
| --Porous metal materials have higher strength and advantages of weld-ability, workability, resistant to hot shock and corrosion. They are widely used as filters, elements for gas diffusion and solid particle fluidization, catalyst supports, porous electrodes, damping materials, flame arrests, sweat cooling materials etc, in petrol-chemical, pharmacy, beverage, metallurgy, nuclear energy, electronics and machine-building industries. A variety porous materials and products of titanium, nickel and its alloys, stainless steel are now available. |

 |
| --Porous metal materials
can have varied porosity, crossed pore and diameter distribution,the
characteristics are: |
| --High temperature
resistance and withstanding rapidly cooling/heating,work temperature
between -200~ 800¡æ |
| --Better corrosion
resistance,suitable in couple of acids and alkalis |
| --High strength and
toughness,used in high pressure state. |
| --Stable hole form,provide
consistent filtration performance. |
| --Good renewability
and long work-life,performance can be recovered by 90% after
retexture. |

--NIN founded the lab of the sinter metal porous material(the predecessor of Baode) in 1960s. It was took up in research and development of porous material, has achieved as much as 100 projects, and has been awarded more than 30 items by province and ministry. It already had mass production.
The research and development of the porous material in NIN was the first taken up in China.NIN is the domestic R&D and production base of the filtration material and filtration equipment.
¡ô1960s founded the lab of the metal porous material, and founded a ntegrated product line of the powder porous material.
¡ô1970s compiled 'Powder Metallugy Porous Material'-exclusive specialized publication in China
¡ô1980s writed 6 national standards
GB6886-86:Sinter stainless steel filtering element;
GB6887-86:Sinter titanium filtering element and material;
GB6888-86:Sinter nickel filtering element;
GB6889-86:Sinter Ni-Cu alloy filtering element;
GB5249-85:infiltrability sinter metal material-- the mensuration of air bubble test;
GB5250-85:infiltrability sinter metal material-- the mensuration of liquid permeability;
¡ô1980s has researched the second generation metal porous filtering material-the metal complex yarn-net.
¡ô1990s has researched the third generation metal porous filtering material- metal fibrofelt, and has taken up the exclusive industry product line in China-- the main industry demonstration project.
¡ô Obtained authorization of Shell Global Solutions for the design and manufacture of SCGP Critical Equipment
