20180172186 · 2018-06-21 ·

A stitched double layer composite hose and a manufacturing method thereof are provided. The stitched double layer composite hose includes a middle fabric pipe layer (1), an inner surface composite colloid material layer (2) and an outer surface composite colloid material layer (3). The structure of the fabric pipe layer is weft-stitched double-layer unit structure. The double-layer unit structure includes an outer layer, an inner layer and stitched wefts. The inner layer includes inner layer warps and inner layer wefts; the outer layer includes outer layer warps and outer layer wefts. The stitched wefts interweave with the outer layer warps and the inner layer warps for conjoining the inner layer and the outer layer together. The fabric pipe layer weaved according to this invention solves problems of the stitched double layer composite hose in the fabric pipe layer of traditional casing, with such advantages as high flexibility, less weaving point, less loss of yarn strength and less degree of torsion. The fabric pipe layer, with special coating equipment and special coating process, can be directly processed into a stitched double layer composite hose satisfying market needs with large caliber, high dielectric strength and higher flexibility. The production process is simple, featured with extremely high utility value and worthy of promotion for production.

Method and apparatus for lining a pipe

The method for rehabilitating a damaged section of a pipe without a need for a resin absorbent liner is provided. The method includes pumping a low viscosity material towards a damaged section of pipe and changing the viscosity prior to dispensing of the material. For example, the material may be partially cured prior to dispensing. The partially cured or higher viscosity material is compressed between an inflating bladder and interior wall of the pipe, and the material that is allowed to fully cure. The bladder either can then be removed from the pipe or could be allowed to maintain in the pipe providing a new interior surface for the repaired pipe.

NANOCLAY SORBENTS FOR DIALYSIS

Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. The nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The montmorillonite, the bentonite, and the other clays may be used in wearable systems, in which a dialysis fluid is circulated through a filter with the nanoclay sorbents. Waste products are absorbed by the montmorillonite, the bentonite, and the other clays and the dialysis fluid is recycled to a patient's peritoneum. Using an ion-exchange capability of the montmorillonite, the bentonite, and the other clays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing a dialysis fluid used in hemodialysis and thus reducing a quantity of the dialysis fluid needed for the hemodialysis.
