摘要:
A flexible fibrous material comprises inorganic fibers and a binder and methods of making the same. The binder comprises at least one of: a first organic polymer having anionic groups and a flocculent, the flocculent comprising a second organic polymer having cationic groups; or a reaction product of the first organic polymer and the flocculent. Flexible fibrous material according to the present invention may be used as components in certain pollution control devices.
摘要:
There is disclosed a honeycomb structure 1 which is made of a ceramic material and in which a plurality of honeycomb segments 12 having cell structures 5 and porous outer walls 7 on outer peripheries of the cell structures 5 are integrated by bonding the outer walls 7 to one another with a bonding material, each of the cell structures being provided with a plurality of cells 3 constituting fluid channels divided by porous partition walls 2, wherein the bonding material contains a bio-soluble fiber. The honeycomb structure 1 of the present invention has a performance equivalent to that of a honeycomb structure in which a heretofore used ceramic fiber is contained.
摘要:
On fabrique une matière textile à revêtement, utilisée notamment comme tissu de filtration durable, à partir d'un substrat textile tel qu'un tissu tissé ayant un revêtement microporeux de polymère de fluorocarbone élastomère. On peut réaliser le substrat en aramide ou en sulfure de polyphénylène ou en fibres de verre. Le polymère élastomère peut être un terpolymère de tétrafluoroéthylène de pentafluoropropène de fluorure de vinylidène. On peut appliquer le revêtement microporeux sous forme d'émulsion aqueuse moussée séchée et broyée mécaniquement.
