  • Patent number: 8262960
    Abstract: First, wood or bamboo is crushed to obtain wood powder with an average grain size of 5 ?m to 100 ?m. Next, the wood powder is put in a first mold, and a first compression molding step is carried out under the conditions that, for example, a temperature is 160° C. and a pressure is 30 MPa. Thus, a temporary molded body is obtained. Subsequently, the temporary molded body is immersed in a flame retardant and a surface of the temporary molded body is impregnated with the flame retardant. Thereafter, the temporary molded body is put in a second mold, and a second compression molding step is carried out under the conditions that, for example, a temperature is 200° C. and a pressure is 100 MPa. At this time, ingredients such as lignin and a hemicellulose are separated from the wood powder, and function as an adhesive. For this reason, pieces of crushed material are firmly bonded with each other so as to be integrated into a single body. Thus, a compression-molded product with a predetermined shape is obtained.

  • Patent number: 8211342
    Abstract: A process for the production of a non-fibrous ultra high molecular weight polyethylene tape having a width of 1-inch or greater and a modulus of 1,400 grams per denier or greater. The non-fibrous UHMWPE tape is obtained by compression molding ultrahigh molecular weight polyethylene powder at a temperature below its melting point and then drawing and stretching the entire resultant compression molded UHMWPE sheet, with no slitting or splitting of the sheet, at a draw ratio of at least 100:1. The UHMWPE tape can be produced in weights of 6,000 to 90,000 denier or greater. The UHMWPE tape of the present invention minimizes the effect of stress concentrators that are prevalent with fibers and thereby enables the tape to be drawn at much higher draw ratios than is possible with fibrous UHMWPE. When used in ballistics panels, the high modulus high molecular weight polyethylene tape of the present invention improves ballistic performance by providing enhanced dissipation of the impact energy of a projectile.

  • Patent number: 8137601
    Abstract: A process for the production of virtually full density polyolefin suitable for further processing by drawing to form a high tenacity, highly oriented polyolefin sheet comprising: a) feeding a metered amount of polyolefin powder into the nip between two heated calender rolls; b) rolling the powder through the nip under these conditions until a coherent sheet of polyolefin is produced. According to a highly preferred embodiment, initially, the nip is set at a gap smaller than the size of the smallest polyolefin powder particle and at a temperature above the melting point of the powder and once a coherent sheet of polyolefin exits the nip the temperature in the nip is lowered to a temperature below the melting point of the polyolefin powder and the gap increased to a desired level above the thickness of the largest powder particle.

  • Publication number: 20120043685
    Abstract: A powder particle shaping device is provided, which includes a closed cavity capable of changing between multiple shapes as an external pressure changes, and the closed cavity compresses and moves powder particles with which the closed cavity is filled full while the shape changes. A powder particle shaping method is further provided, which includes a. filling a closed cavity full with powder particles to be shaped; and b. applying a varying external pressure to the closed cavity, such that the closed cavity changes repeatedly between multiple shapes, thereby making the powder particles under compression move and be subject to friction. The shaping device and method according to present invention have highly controllable shaping processing intensity of powder particles and stable processing strength, and thus are applicable to shaping and pulverization of various powder particles, and also applicable to pulverization and further shaping processing of dispersed agglomerates.

  • Patent number: 8021508
    Abstract: The present invention is directed to a method for manufacturing a panel containing wood fibers. The wood material is cut into strands having a thickness and a width perpendicular to the grain direction and a length parallel with the grain direction, the length being significantly greater with respect to the other dimensions. An adhesive is applied to the strands, the glued strands are formed into an assembly, wherein the strands are substantially parallel in the longitudinal direction, and the strands remaining substantially parallel in the longitudinal direction are extruded by applying a thrusting force substantially perpendicular with respect to the longitudinal direction of the strands.
