摘要:
Mounting materials for pollution control devices comprising biosoluble fibers, heat treated silica fibers having a silica content of greater than about 67 percent by weight (pbw) based on a total weight of the fibers, and intumescent material, with an optional binder component, are disclosed. Methods for making and using the materials are also disclosed.

The fluid delivery system includes a fluid path set with a first section adapted for connection to a syringe and to a source of fluid to be loaded into the syringe, and a second section that is removably connected to the first section. A connector removably connects the first and second sections. The connector includes a first connector member having a first luer member and a first annular member disposed about the first luer member. The connector further includes a second connector member having a second luer member and a second annular member disposed about the second luer member. A check valve arrangement is disposed in of one of the first and second connector members for limiting fluid flow to one direction through the connector. The first and second annular members are adapted to operably engage to securely and releasably connect the first and second connector members.

The present invention relates to a fiber mat, preferably a non-intumescent, polycrystalline, needle-punched or stitch-bonded aluminia-silica fiber mat, which contains an organosilicon compound. The fiber mat comprises a fiber blanket which is essentially free of organic binder and which is impregnated with an organosilicon compound selected from the group consisting of siloxane compounds, alkoxy group-containing silanes, hydrolysates and condensates of these compounds, and combinations thereof. In a further embodiment the fiber mat comprises a high friction coating on at least the side of the mat which is to be brought in contact with a pollution control element of a pollution control device. Furthermore, the present invention relates to a pollution control device containing such a fiber mat.

摘要:
A method of making mounting mats comprising the steps of: (i) supplying inorganic fibers through an inlet of a forming box having an open bottom positioned over a forming wire to form a mat of fibers on the forming wire, the forming box having rollers for breaking apart clumps of fibers and an endless belt screen; (ii) capturing clumps of fibers on the endless belt; (iii) conveying captured clumps of fibers on the endless belt so as to enable captured clumps to release from the belt and be broken apart by the rollers; (iv) transporting the mat of fibers out of the forming box by the forming wire; and (v) compressing and restraining the mat of fibers to thereby obtain a mounting mat having a desired thickness suitable for mounting a pollution control element in a pollution control device.
