The present invention discloses a composite ribbed expanded polystyrene pallet and a manufacturing method thereof, comprising a body and a base support, said base support clads the sides and bottom of the body, said body is made of expanded polystyrene, said comprises a pallet platform and plural supporting feet. Through the above mentioned way, the present invention utilizes light-weight polystyrene to make the body, the surface is covered with a base support of high-strength engineering plastic film, and reinforcing ribs are additionally arranged inside the body through special process. The pallet of the present invention has good load bearing performance, economy and practicability. The logistics cost also can be reduced greatly. Therefore, the composite ribbed expanded polystyrene pallet and the manufacturing method thereof have broad market prospects in popularization.

The application relates to a method and apparatus for producing a solid foam continuously. A homogeneous suspension is formed from a raw material in which the suspension comprises a solidifying agent, and a foam mixture which comprises bubbles is formed by mixing air bubbles into the suspension. The foam mixture is injected via at least one nozzle to form a foam pattern and the foam pattern is laid on a moving surface and the foam mixture of the foam pattern is solidified in order to form a solid foam such that the bubbles of the foam mixture shrink in off-length directions to form the shaped bubbles. Further, the application relates to the product and the use of the method.

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable having a scalloped periphery, the braid can be infiltrated with membrane polymer which, when coagulated, embeds the braid positioning it around the lumen. The embedded spiral weave, free of any circumferentially constricting monofilament, allows the membrane to be biaxially distensible. The membrane has give not only in the axial or longitudinal direction but also in the radial direction. Give in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.

A method of manufacturing a polymer composite comprising a polymer phase and agro-waste particles dispersed in the polymer phase, wherein the polymer phase is preferably obtained from polyolefin containing waste plastics, and the agro-waste particles are preferably obtained from date palm wood flour particles. Various combinations of embodiments are provided.

A method of producing a stretch-blow-molded article, comprising: a process of producing a preform from a melt-kneaded product of a resin mixture comprising at least a wax, a styrene-based resin and a carbodiimide compound; and a process of stretch-blow molding the preform to produce the stretch-blow-molded article.

A manufacturing method of a composite ribbed expanded polystyrene pallet, which includes prefabricating the base support according to the bottom shape of the body; placing the base support in a concave mold matched with the base support; placing the plural reinforcing ribs on a supporting bracket of a raised mold; forming a mold cavity; and injecting ore-expanded polystyrene particles to produce the body, meanwhile the body is combined with the base support to form the pallet; wherein the reinforcing ribs are fixed by the supporting bracket, one end of which is provided with a spring leaf configured to engage the plural reinforcing ribs, during production process, the free end of the spring leaf inserts into the process hole to fix the reinforcing ribs, after completion of forming process, the free end of the spring leaf is removed together with the raised mold, while the reinforcing ribs stay inside the body.

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem common in prior art multifilament braid-supported tubular membranes. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable it can be infiltrated with membrane polymer which, when coagulated embeds the braid positioning it around the lumen. The spiral weave, free of any circumferentially constricting monofilament, when embedded in film, allows the membrane to be biaxially distensible. In other words, the membrane has give not only in the axial or longitudinal direction but also in the radial direction. Give in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.
