摘要： One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti-jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti-jamming characteristics of the product in the hopper.

摘要： The present invention belongs to the technical field of functional film materials; disclosed are a wavelength-controllable cellulose iridescent film and a method for preparation thereof. The method is: (1) mixing well a cellulose nanocrystal (CNC) suspension with lactic acid solution and glucose solution to obtain a CNC/lactic acid/glucose mixed solution; said CNC suspension being a cellulose nanocrystal suspension; (2) drying the CNC/lactic acid/glucose mixed solution to form a film to obtain a cellulose iridescent film. The method of the present invention is simple and low in cost. In the present invention, by means of the addition of lactic acid and glucose, the prepared film has iridescent film characteristics; the wavelength of the iridescent film is within the range of visible light, and the wavelengths of different colors of iridescent film are controllable.
