摘要： A sealing material is presented which can be applied to surfaces and/or to surfaces having seams, cracks, crevices and the like to hinder growth and colonization of bacteria while maintaining adhesion over a wide range of service, or use, conditions. The sealing material includes a fluoropolymer layer, a reinforcing layer and an adhesive for adhering the sealing material to the surface or surfaces to be sealed. The invention combines the inherent anti-stick and hydrophobic properties of fluoropolymers with excellent adhesive characteristics.

摘要： A quench bath, for quenching and solidifying an extruded hollow porous fiber of a liquid polymer solution in a chemical quenching solution, includes a shallow quench bath of a length for the generally horizontal part of the extruded fiber travel in the bath. A vertical extension tube with its lower end beneath the surface of the bath liquid holds a spinneret through which the fiber is extruded. The spinneret is sealed in the tube above the height of the liquid in the shallow bath. A vacuum drawn in the tube raises the liquid up to the spinneret. Also, the vacuum may be drawn by disposing the spinneret in a sealing piston which is raised through the tube to draw the vaccum in the tube behind the piston.
