  • Publication number: 20110121482
    Abstract: A method of forming a chopped strand mat formed of bonding materials and wet use chopped strand glass fibers (WUCS) which demonstrate a reduced occurrence of static electricity is provided. In one exemplary embodiment, the occurrence of static electricity on the glass fibers is reduced or eliminated by increasing the total solids content on the glass fibers, such as by applying an increased or excess amount of size composition to the glass fibers. Alternatively, an anti-static agent may be added directly to the sizing composition and applied to the glass filaments by any suitable application device. The antistatic agent may be applied to the wet chopped strand glass prior to chopping the strands or as the wet chopped strands are packaged. The static free wet use chopped strand glass fibers may be used in dry-laid processes to form chopped strand mats having a reduced tendency to accumulate static electricity.

    Abstract: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed.

A coloring solution is discharged from the fluid discharge head when each layer is deposited to color the sheet material. After the deposition is completed, the unnecessary parts of the sheet material can be pulled away to complete the three-dimensional model. Alternatively, by discharging a setting solution using a nozzle of the fluid discharge head onto each layer of the sheet material, each layer of the sheet material in the section area of the three-dimensional model can be insolubilized, and a color setting solution can be discharged to color and set the colored parts.

    Abstract: A process for producing a new material consists of utilising pieces of waste material which are to be discarded from a process of scrapping a product such as a vehicle where the product is passed through a shredding machine (12) which shreds, chops or fragments the product which is to be scrapped into small pieces and after at least part of the re-useable pieces have been recovered, mixing or coating (22) the remaining waste material with an encapsulating material for wholly or partially encapsulating the waste material therein to form a new composite material.

  • Patent number: 7445738
    Abstract: A multi-layer process for producing structural cementitious panels, includes, a. providing a moving web; b. one of depositing a first layer of loose fibers upon the web and c. depositing a layer of settable slurry upon the web; d. depositing a second layer of loose fibers upon the slurry; e. embedding said second layer of fibers into the slurry; and f. repeating steps c. through e. until the desired number of layers of settable fiber-enhanced slurry in the panel is obtained. Also provided are a structural panel produced by the present process, an apparatus suitable for producing structural cementitious panels according to the present process, and a structural cementitious panel having multiple layers, each layer created by depositing a layer of settable slurry upon a moving web, depositing fibers upon the slurry and embedding the fibers into the slurry such that each layer is integrally formed with the adjacent layers.

  • Publication number: 20080179777
    Abstract: A polyolefin-containing material including an internal additive, where the internal additive is a triglyceride according to the structure (T): CH2(OR1)—CH(OR2)—CH2(OR3) ??(T) where R1, R2 and R3 are, independently of one another, saturated, mono- or poly-olefinically unsaturated acyl groups containing 8 to 24 carbon atoms, the chain lengths of the acyl groups are the same or different, and the polyolefin-containing material exhibits improved softness is provided. A process for the softening finishing of articles including polyolefins is also provided and includes adding a triglyceride to polymer granules including a polyolefin present in an amount of from about 0.1% to about 40% by weight, based on the weight of the granules, and subjecting to further processing to form a fiber or film.

  • Patent number: 7396438
    Abstract: A method of making a formed, dried lignocellulose fiber material comprising (a) providing an aqueous lignocellulose fiber pulp slurry having an effective consistency; (b) de-watering the slurry to provide a de-watered material at an effective de-watering rate under an effective pressure to prevent or reduce the formation of fissures and voids within the material; (c) drying an effective amount of the de-watered material at an effective temperature and period of time to provide the formed, dried lignocellulose fiber material having a thickness of at least 5 mm. The formed, dried lignocellulose material may be used to make a lignocellulose fiber-resin composite material of use as a cost effective structural member, as a substitute for steel, in, for example, bridges, processing equipment, and the like.

  • Publication number: 20080145630
    Abstract: Densified non-woven materials having acoustic and thermal properties are provided. The non-woven material is formed of a thermoplastic material or fibers and a thermoplastic material. The fibers may be an organic, inorganic, or thermoplastic fiber and are desirably devoid of conventional sizing compositions. The densified portion of the non-woven material is formed by applying a moisture additive and subsequently applying heat. Heating the non-woven material causes the water in the moisture additive to turn to steam, which causes a molecular change in the polymer based thermoplastic material(s) of the non-woven material that was treated with the moisture additive. The moisture additive is preferably water, but may include a dilute alkali, a dilute acid, or additives to enhance surface, fire, or mold release characteristics. The water additive may be utilized to surface treat, partially treat, or completely treat the air-laid mat to achieve desired acoustic or thermal properties and/or stiffness.
