7 results about "Cuprammonium rayon" patented technology

Cuprammonium rayon is a rayon made from cellulose dissolved in cuprammonium solution. It is produced by making cellulose a soluble compound by combining it with copper and ammonia. The solution of this material in caustic soda is passed through the spinneret and the cellulose is regenerated in the hardening baths that remove the copper and ammonia and neutralize the caustic soda. Cuprammonium rayon is usually made in fine filaments that are used in lightweight summer dresses and blouses, sometimes in combination with cotton to make textured fabrics with slubbed, uneven surfaces.

Novel cellulose coated diaphragm and preparation method thereof

The invention provides a novel cellulose coated diaphragm and a preparation method thereof, and the preparation method comprises the following steps: preparing a 10wt% saturated copper ammonia solution, adding a low-cost cellulose raw material into the copper ammonia solution according to a mass ratio of 1: (8-12), and stirring for 40-60 minutes at 25-30 DEG C and 200-300 r / min to obtain a copper ammonia fiber solution; the preparation method comprises the following steps: coating the surface of a polyolefin base membrane with the coating by using an automatic coating machine to form a 1-3 [mu] m coating, immersing in a 10-20% coagulating bath, standing at 25-30 DEG C for 1-3 min, curing, washing with water until the pH is 6.8-7.2, rolling at 2-30 MPa, and drying at 60 DEG C for 60 min to obtain a finished product. The diaphragm contains the polyolefin base membrane and the cellulose coating, and is good in thermal stability, high in ionic conductivity, low in raw material cost, simple in process, biodegradable and suitable for large-scale industrial production, and the electrolyte absorption rate reaches 68%-72%.
