  • Publication number: 20120326355
    Abstract: A sulfur-containing material in a melt state is stored in material hopper heated to a temperature within a preset temperature range of which a lower limit is equal to or above a melting point of sulfur. The stored sulfur-containing material is sucked by pressure generators and pulled out into cylinders heated to a temperature within the preset temperature range. The pulled out sulfur-containing material is pushed out from the cylinders under pressure applied by the pressure generator, and thereafter, the resultant material is injected into mold heated to a temperature within the preset temperature range. An injection port of the mold after the sulfur-containing material is fully injected is closed. By stopping heating of the mold, the sulfur-containing material is slowly cooled. After that, a modified sulfur concrete substance formed by cooling and solidifying the sulfur-containing material is taken out from the mold.

  • Publication number: 20120133071
    Abstract: A method for producing leather pellets, and a method for producing compound granules from leather pellets and a polymer material, for use in molded parts or films. The leather pellets are produced through the following steps: Shavings, crust leather remnants and finished leather waste are obtained as waste products in leather production and finished leather processing; the shavings, crust leather remnants and finished leather waste are milled into ground leather stock comprising leather fibers; the ground stock is pressed into leather pellets; and the leather pellets are dried to a residual moisture content of no more than 30% by weight. The leather pellets can be mixed with a polymer material at a ratio of 10-95% by weight and bonded to one another and shaped forming compound granules. The compound granules can be used to produce molded parts by injection molding or films by calendering.

  • Patent number: 8076146
    Abstract: A method for evaluating rubber is provided which can evaluate the degree of crosslinking of a crosslinked rubber product within a short period of time without performing any specific treatment. In the above method, the amount of energy shift of the peak (such as the peak of C12p3/2 of chlorinated butyl rubber) of a constituent element of the rubber is measured by photoelectron spectroscopy, and the degree of crosslinking of the rubber is evaluated from the amount of energy shift. In addition, a method for manufacturing a rubber product is also provided which includes the steps of measuring the amount of energy shift of the peak of a constituent element of the rubber product by a photoelectron spectrometer which is installed in a manufacturing line and then feeding back measurement result to adjust heat molding conditions so as to obtain a desired degree of crosslinking.
