METHOD FOR PRODUCING SYNTHETIC RESIN MOLDED ARTICLE IN WHICH MARINE FLOATING PLASTIC WASTE IS USED
The present invention provides a method for manufacturing a synthetic resin molded product which does not require classification of recovered ocean floating plastic trash according to kind of plastic, and can reuse most thereof as a raw material. The method is characterized by including mixing ocean floating plastic trash P (30 to 80 wt %) having a diameter or a side of 5 mm or less or a weight of 0.1 g or less, and a woodchip W (second material) (20 to 70 wt %) having a diameter or a side of 5 mm or less, and not molten under a temperature condition of 200° C. by a mixer 3, supplying a mixture of the ocean floating plastic trash P and the woodchip W to a grinding device 4, grinding the mixture into a powder with a diameter or a side of 1 mm or less, supplying the resulting powder as a raw material for a synthetic resin molded product to a molding machine, and carrying out a molding step.
Apparatus and method for composite material
The present invention provides an apparatus for recycling composite material and a method for recycling composite material by using same, the apparatus including: a mixing tank in which pulverized products of fiber-reinforced waste plastic are dispersed and mixed in water together with a filler, thereby forming a composite material mixture; a fixing agent addition part for forming a recyclable material by supplying, to the composite material mixture, a fixing agent that aggregates the pulverized products of the fiber-reinforced waste plastic and the filler; and a filtering tank in which the recyclable material is supplied such that a recyclable composite sheet is formed.
Method and mixing plant for the batch-based production of a flowable coating material
Disclosed is a method for the batch-based manufacture of a flowable coating material, in particular water-based or solvent-containing paint, from a plurality of components. The method includes feeding batch components into a process mixing container, mixing the components in the process mixing container to form a mixture having a preliminary composition, transferring at least part of the mixture having the preliminary composition from the process mixing container into a reception container, ascertaining an actual state of the mixture having the preliminary composition during transfer into the reception container, determining a deviation of the actual state of the mixture having the preliminary composition from a predefined setpoint state, ascertaining an adjustment quantity for the components required to reach the setpoint state, and topping up the adjustment quantity of the components into the preliminary mixture, while the preliminary mixture is being transferred from the process mixing container into the reception container.
PROCESS FOR FEEDING PLASTIC WASTE MATERIAL TO A THERMOCHEMICAL OR PYROLYSIS REACTOR
Process for feeding plastic material, e.g. a plastic waste, to a processor such as a thermochemical reactor, e.g. a pyrolysis reactor. The process comprises an optional shredder or disintegrator (1), a conveying system (2), a feed hopper (3) with a lock hopper or rotary valve, a melting tank (6) with an agitator (5) followed by a melt pump (7) for the delivery of molten plastic to the processor. The advantage of the current process includes the ability to supply a consistent, metered flow to the processor, independent of the recycled plastic's melt properties, or the form or particle size and distribution of the plastic material.

PLASTIC PROCESSING SYSTEM AND APPARATUS
Described is a method of manufacturing a binder and the use of the binder to manufacture a roading mixture through mixing with aggregate, or a composite plastic product through the mixture of binder with particulate matter and/or fibre. The binder comprises mixing a plastic with two or more ethylenically unsaturated monomers in a mixing tank. The two or more ethylenically unsaturated monomers may have different homopolymer glass transition temperatures (TO wherein a first monomer structural unit has a homopolymer T.sub.g of greater than 80° C. and a second monomer having a homopolymer T.sub.g of less than 80° C. The plastic may be selected from a plastic comprising a styrene homopolymer, a styrene copolymer, a copolymer of an alkene and vinyl acetate, acrylic polymer and nylon based polymers or co-polymers, polyester-based thermoplastic polymer resin, propylene-based thermoplastic polymer and homo-polymer of an alkene or combination thereof.
THERMOKINETIC MIXER FOR MELT-MIXING WASTE PLASTIC PRODUCTS
A thermokinetic mixer for melt mixing plastics waste includes a housing enclosing a mixing chamber, and a shaft protruding through the mixing chamber and connectable to a drive unit. In the mixing chamber, Y-shaped mixing blades protrude radially from the shaft, wherein the free end of the mixing blades protruding into the mixing chamber is cuboid, and the end opposite the free end of the mixing blades has two legs in each case having at least one through bore. The shaft has polygonal recesses, in which recesses the legs can be fastened by a fastener protruding through the through bores.
