37 results about "Super black" patented technology

Super black is a surface treatment developed at the National Physical Laboratory (NPL) in the United Kingdom. It absorbs approximately 99.6% of visible light at normal incidence, while conventional black paint absorbs about 97.5%. At other angles of incidence, super black is even more effective: at an angle of 45°, it absorbs 99.9% of light.

High-permeability super black decorated base paper and preparation method thereof

The invention relates to high-permeability super black decorated base paper and a preparation method of the high-permeability super black decorated base paper, and belongs to the technical field of decoration base paper. The preparation method is characterized by comprising the following steps: taking pulp mixed from bleached softwood pulp and bleached hardwood pulp according to the mass ratio of 1:(3.6-4.4) as a main raw material; reducing the beating degree of bleached wood pulp to 32 SR, enabling the mass concentration to reach 4%, and then pumping into a repulping pond for later use; directly adding a black pigment to the repulping pond, wholly substituting kaoline for titanium dioxide to prepare the decorated base paper with a black and shiny color, the fluorescent whiteness of 6%-8%, the basis weight of 70-90g/m<2>, the ash content of 10%-15%, the wet strength of 6.5-9N, the dry strength of 35-50N, the water absorption of 20-35mm/10 minutes and the air permeability of 15-20s/100ml. The high-permeability super black decorated base paper disclosed by the invention has the advantages of uniformity in coloring, good covering power, high air permeability, low basis weight and high paper output ratio; a processed decorating plate is high in stereoscopic impression, pure and bright in color and luster, green and environmental-friendly without white patterns.

Method for producing fine-denier glazed super-black terylene FDY (Fully Drawn Yarn) filament yarn

The invention relates to a method for producing a fine-denier glazed super-black terylene FDY (Fully Drawn Yarn) filament yarn. The method comprises the following steps of (a) weighing 92%-94% of glazed PET (Polyethylene terephthalate) slices and weighing 6% of black master-batches to dry; (b) blending the dried glazed PET slices with the dried black master-batches, and putting the mixture into a screw extruder so as to form PET flux; (c) filtering and pressurizing the PET flux, and distributing the pressurized PET flux to all spinneret components for producing nascent fibers through a metering pump; (d) winding-forming the nascent fibers by means of cooling the nascent fibers through side blowing, oiling the nascent fibers through an oil nozzle, performing stretching-setting operation on the nascent fibers, and gridding the nascent fibers, wherein the speed of a first heat roller for the stretching-setting operation is 1,500-2,000 m / min, and the temperature of the first heat roller is 80-90 DEG C; the speed of a second heat roller is 4,000-4,500 m / min, and the temperature of the second heat roller is 120-130 DEG C; the winding speed is 4,000-4,500 m / min, and the winding tension is controlled to be 10-15 N. According to the method for producing the fine-denier glazed super-black terylene FDY filament yarn, on one hand, the glazed PET slices and the black master-batches are blended and prepared into the PET flux, so that the PET flux can be used for preparing the glazed super-black terylene FDY filament yarns; on the other hand, the prepared filament yarns are fine-denier yarns by means of adjusting the speeds of the first heat roller and the second heat roller as well as the winding speed.
