Abstract: An improved method for refining cellulose that produces a highly refined cellulosic material comprising soaking raw material in a mild NaOH using reduced temperatures and pressures, and refining the material with a plate refiner so that a waste water stream is reduced in volume and has a pH within a range of 8 to 9. Also, a HRC gel having a lignin concentration of at least about one (1)% by weight, and a water retention capacity of about 25 to at least about 56 g H2O/g dry HRC is provided.

Abstract: An adhesive tape seat has a main body, a push bar, a blade, a hollow adhesive tape cylinder, and a supporting strut. The supporting strut positions a rear end of the adhesive tape cylinder. The main body has fasteners at two sides of the main body. At least an outer ring which encloses the adhesive tape cylinder abuts the supporting strut. The hollow adhesive tape cylinder receives a compression spring, the first washer and a supporting rod therein. The front portion of the supporting rod is inserted through the compression spring to reach a nut. The nut covers the orifice at the front end of the adhesive tape cylinder. The rear portion of the supporting rod is inserted through the first washer, a through hole on the supporting strut and the second washer.
