摘要:
The present invention relates to a resin binder composition, a filter medium comprising the resin binder composition as well as related methods and uses.
摘要:
The invention relates to a single or multi-layer filter material, comprising at least one layer made of cellulose, glass fiber, synthetic fiber, or a mixture thereof, and saturated with a binding agent made of an epoxy resin and a curing agent. The hardening agent comprises a first hardener cross-linking at a lower temperature, and a second hardener cross-linking at a higher temperature, so that the epoxy resin can be hardened stepwise depending on the temperature.
摘要:
The invention relates to an abrasive support comprising a support material composed of at least one wet- or dry-laid nonwoven based on natural and/or synthetic fibers. The support material is impregnated with a thermally curable polymer solution on one side and with an aqueous polymer dispersion on the opposite side. The thermally curable polymer solution penetrates at least 50% and at most 80% of the thickness of the support material, while the aqueous polymer dispersion penetrates at least 25% and at most 50% of the thickness of the support material.
摘要:
A filter material for separating liquids from fluid flows comprises a wet- or dry-laid nonwoven, woven fabric, or an open-cell foam. The two sides of the filter material are impregnated with two different binders in such a way that one side of the filter material has a higher amount of surface energy and thus a shorter drop sink-in time than the opposite side.
摘要:
The invention relates to a filter material comprising a carrier material that is impregnated on one side (1) with a thermally pre-crosslinked binder system (VB) and on the other side (2) with a thermally crosslinkable but un-crosslinked binder system (UB). The filter material is characterised by improved deformability and a very good level of heat sealability, particularly using ultrasound, and a low pressure differential particularly when filtering high-viscosity liquids.
摘要:
The invention relates to a filter material impregnated on one side with a binding agent that is in particular suited for gas filtration, wherein the filter material comprises a side that is not impregnated with a binding agent, which side contains a halogen-free and boron-free flame protection means. By means of the filter material according to the invention, a high separation rate and a high dust storage capacity are achieved, whereas the filter material is flame-retardant, and in the event of fire, does not release any toxic decomposition products. The invention further relates to a filter element comprising the filter material according to the invention.
