摘要： A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 μm and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.

摘要： A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, capturing an image of a test pattern through the polymer film, calculating a modulation transfer function value from the image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the calculated modulation transfer function value.

摘要： An ultra-high-molecular-weight fiber manufacturing method is provided. The method includes: removing moisture in a mixed liquid to form a to-be-processed raw material, and supplying the to-be-processed raw material to a spinning device, where the spinning device heats the to-be-processed raw material in different stages, to make the to-be-processed raw material form a semi-molten state and be extruded toward a discharge outlet, to spin at least one fibril; cooling the at least one fibril, to form a first wire; if hardness of the first wire is not in a hardness range, selecting at least two discontinuous heating zones located in the spinning device to perform temperature adjustment; stretching, heating, and re-stretching the first wire, to form a second wire; winding the second wire around a drum; and stretching, drying, and re-stretching the second wire, to form a final wire product.

摘要： The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to a respective thermoelement, is arranged on the first nozzle lip, the thermoelements being controllable by the regulation in such a way that the slot can be adjusted by the action of a mechanical force from the respective adjusting element on the first nozzle lip, as a result of the expansion or contraction of the thermoelements. At least two adjusting elements are adjusted simultaneously. The invention further relates to a control and/or regulation system.

摘要： A self-cleaning dosing apparatus includes a material hopper for containing pellets of material, a feed screw, a first material outlet through which pellets of material fall by gravity onto a first end of the feed screw for the feeding of pellets to a process machine. A second material outlet is located beneath the first end of the feed screw, with a slide gate blocking the second material outlet. A pneumatic piston is provided for pulling the slide gate to unblock the second material outlet, and a Venturi pump is located under the second material outlet for pulling pellets through the second material outlet when the slide gate is opened.
