A method for producing a microfibrillated cellulose, which comprises subjecting a slurry containing a pulp having a solids concentration of 1 to 6 wt % to the treatment with a disc refiner repeatedly ten times or more, to thereby prepare a microfibrillated cellulose having a number average fiber length or 0.2 mm or less and an amount of water hold of 10 mL / g or more, the amount representing the volume of water capable of being held by a unit weight of the cellulose fiber. The method allows the production of a microfibrillated cellulose having high quality with stability and with good efficiency.

A thin decorative thermosetting laminate of postforming quality is glued to a longitudinal carrier to form a floor strip. The laminate has a thermosetting resin as well as hard particles impregnated therein to increase the abrasion resistance of the laminate. The carrier generally has a cross section of a dilatation, transition or a finishing profile, depending on the intended use of the floor strip. The floor strip has a tab portion on a surface that engages a channel on a floor tile or a reducer. The tab portion locks the floor strip into place and prevents movement of the floor tile or the reducer with respect to the floor strip.

The invention relates to a exquisite kraft paper and the preparation method, which is that: more than 60% masson pine, less than 15% Chinese fir and less than 40% hardwood are prepared, steamed and boiled, washed and screened, oxygen delignified and blesched, then is made into a sulfate micro-bleaching pulp, the whiteness of the pulp is 24-34%, the beating consistensy is 3.5-4.0%, the beating degree is 26-34 degree SR, and the wet weight is 10-15 g. after carried on beating, the kraft paper is made by that the pulp is carried on desanding, flavoring, the fine screening of a pressure screen, molding, pressing, drying, curling, rewinding and packing. The quantitative product is 40-120 g / M<2>, the broke resistance index is less than 1.7 Kpa.m<2> / g, the surface water absorption is 25-45 g / M<2>, the whiteness is 21.5-30%, the water content is 6-11%, the lead content (weighting as Pb) is less than or equal to 3 mg / kg, the arsenic content (weighting as As) is less than or equal to 0.8 mg / kg, the fluorescent substances are 254 nm and 365 nm, the decolorization test (water, n-hexane) shows negative, the coliform group content is less than or equal to 30 per 100 g, and the pathogenic bacteria content is 0.

A die detachment device for delaminating a die which is mounted at a position on an adhesive film comprises a plurality of movable plates having quadrilateral-shaped contact surfaces which are arranged adjacent to one another. The plurality of movable plates comprises an intermediate movable plate and outer movable plates on opposite sides of the intermediate movable plate. The contact surfaces of the movable plates together form a combined contact surface for supporting the adhesive film at the position of the die, each movable plate being movable relative to the other movable plates towards and away from the die.

A method for producing micro fibrillated cellulosic material from pulp where multiple passes through a medium consistency refiner are made either singularly or in combination with low consistency refiners and high consistency refiners.
