Method of making structural members using waste and recycled plastics

Номер: US20120007284A1
Автор: Darrel S. Nelson, James M. Oliver
Принадлежит: Nelson Darrel S, Oliver James M

A composite formulation consisting of agglomerated industrial/residential sewer sludge and recycled high density polyethylene (HDPE) and/or polypropylene (PP) materials. The recycled plastic materials act as a binder for the pozzolan industrial/residential sewer sludge. The composite formulation can be produced in a batching process wherein the sieved dried sewer sludge and the recycled plastic in appropriate small cut pieces is fed into a large plastic extruder, heated and extruded into specific structures. The formulation can also be compounded using a compression mold wherein sieved dry sewer sludge are added to heated chopped recycled plastics and heat mixed to produce pellets or directed into a compression mold to create a structural member of predetermined shape.

Polymer pelletization via melt fracture

Номер: US20130234357A1
Автор: Tim Andreas Osswald, William Maurcio Aquite
Принадлежит: WISCONSIN ALUMNI RESEARCH FOUNDATION

Polymer pellets are formed using air to influence the separation of polymer from a polymer melt. In accordance with one or more embodiments, a polymer material is extruded through a nozzle to form a polymer melt extending from the nozzle. A non-uniform thickness is generated in the polymer melt using a gas or gasses to apply a drag force to the polymer melt. This drag force reduces a thickness of a portion of the polymer melt adjacent the nozzle, and the polymer melt is fractured into discrete droplets at the reduced thickness. The discrete droplets are then solidified to form pellets.

Method for starting up a processing plant for producing plastics material granulate and processing plant for producing plastics material granulate

Номер: US20130285276A1
Автор: Hans-Joachim Samann, Klaus Kapfer, Michael Ahlgrimm, Peter MUNKES
Принадлежит: Coperion GmbH

In a processing plant for producing plastics material granulate, the start-up takes place in such a way that a screw machine is firstly driven by means of a drive device and then plastics material to be processed is fed by means of a metering device into the screw machine. At least one conveying position of the plastics material in the screw machine is determined by means of a control device by evaluating at least one measuring signal. Depending on the conveying position determined, a granulating device is activated and put into operation. The method according to the invention allows a direct start-up of the processing plant without the use of a start-up valve. This ensures an easy and safe start-up of the processing plant.

CELLULOSIC MICROPOWDER PRODUCTION SYSTEM

Номер: US20180009133A1
Автор: Hata Seiji
Принадлежит: Biomass Conversions, LLC

An improved process is provided for reducing cellulosic biomass into air suspendable micropowder. Although the process is particularly suitable for processing empty fruit bunches of oil palms, it is adaptable to most cellulosic biomass. The incoming biomass has a water content of around 50% and is reduced to centimeter scale pieces by a chipper or similar device. These pieces are then processed by a tandem line of four pairs of grooved rollers each successive roller having a larger number of grooves. This process squeezes moisture from the biomass and reduces the material into millimeter scale pieces. After an optional drying stage, the material is fed into a terrace line of three or four essentially smooth rollers which squash the material and reduce the particle size into a micrometer scale. Finally, the material is suspended in an air stream and fractionated by a cyclone and bag filter system. 1. A process for efficiently and rapidly reducing the particle size and moisture content of cellulosic biomass comprising the steps of:feeding centimeter scale cellulosic biomass pieces into a squeezer tandem roller line comprising a series of paired rollers having interdigitated surface grooves with successive roller pairs having a larger number of grooves thereby squeezing moisture from the biomass and reducing the squeezed biomass to millimeter scale particles;conducting the squeezed biomass into a terraced squasher roller line comprising a series of paired rollers arranged so that the first roller pair is above the successive roller pair with the surfaces of the rollers being essentially smooth and with each roller pair having a scraper plate to scrape biomass material from the roller surface thereby reducing the squashed biomass into submillimeter scale particles; andsuspending the squashed biomass in an air stream which passes into a filter system which directs larger biomass particles back to the squasher roller line for additional processing and passes smaller ...

PREPARATION OF BIMODAL RUBBER, THERMOPLASTIC VULCANIZATES, AND ARTICLES MADE THEREFROM

Принадлежит:

Pellet-stable olefinic copolymer bimodal rubber is made using parallel reactors, with one reactor synthesizing higher molecular weight (MW) rubber with dual catalysts, with an improved molecular weight split ratio and an improved composition distribution of the moderate and ultra-high MW components, while another reactor synthesizes random isotactic polypropylene copolymer (RCP). The effluents are reactor-blended and result in pellet-stable bimodal rubber (P-SBR), which may be pelletized. When making thermoplastic vulcanizates (TPVs) with P-SBR, the need to granulate rubber bales and subsequently use talc, clay, or other anti-agglomeration agents to prevent granulated rubber crumbs from agglomerating are eliminated. TPVs made with P-SBR have vulcanized rubber particles that are smaller and more uniform in size, resulting in TPVs with higher particle counts and more thermoplastic “ligaments” between the particles, with such ligaments being made stronger by the added RCP. Such thus-produced TPVs have a lower hysteresis and flexural modulus, and better elastic properties. 1. A method of preparing a pellet-stable olefinic copolymer bimodal rubber , comprising:producing a high molecular weight olefinic copolymer rubber characterized by a bimodal molecular weight and a bimodal composition distribution (“bimodal rubber”) within a first reactor;concurrently producing isotactic polypropylene random copolymer (RCP) within a second reactor, wherein the first and second reactors are operated in parallel to each other;obtaining an effluent from the first reactor;obtaining an effluent from the second reactor;reactor-blending the effluents in situ to thereby produce a pellet-stable RCP-containing bimodal rubber (“pellet-stable bimodal rubber”), wherein about 80-97.5 wt % of the bimodal rubber is blended with about 2.5-20 wt % of the RCP, and optionally pelletizing the pellet-stable rubber.3.
