The invention discloses a stirring extrusion type hair dyeing comb. The hair dyeing comb comprises a hair dyeing comb shell; a cylinder cover and a comb head are arranged on the hair dyeing comb shell; a stirring mechanism is arranged in the hair dyeing comb shell; the stirring mechanism comprises a cylinder, a stirring shaft and a driving motor; the stirring shaft is arranged in the cylinder, thedriving motor is connected with the stirring shaft and drives the stirring shaft to move along the inner wall of the cylinder, the cylinder is provided with a feeding port and a discharging port, thecylinder cover covers the feeding port, the discharging port is located at the lower end of the cylinder and communicated with the comb head, and an elastic normally-open switch is arranged at one end, close to the inner wall of the cylinder, of the discharging port. The hair dyeing comb has the beneficial effects that the hair dye in the hair dyeing comb is sufficient in stock, and the two hairdyeing pastes can be uniformly stirred; the hair dyeing comb can quantitatively, sufficiently and efficiently extrude the hair dye; the hair dyeing comb is electrically driven to stir and does not need to be manually pressed; the stirring mechanism can fully extrude the hair dye, and the residual amount of the hair dye in the cylinder is small.

A centrifugal separator includes a cylindrical bowl, a core tube assembly, and an annular piston disposed around the core tube assembly and inside the inner surface of the bowl. Feed liquid is injected down the core tube assembly into the lower portion of the bowl, raising the annular piston. During a separation mode, the bowl rotates at high speed, separating solids from the feed liquid to accumulate along the inner surface of the bowl, while collecting clarified centrate as it exits the top of the bowl and through the core tube assembly. Following solids accumulation, bowl rotation is stopped and residual liquid is pumped from the bowl. In a solids discharge mode, the annular piston is urged downward along a vertical axis in response to compressed gas. The downward movement of the piston forces accumulated solids from the bowl via an opening in the lower end thereof.

Polymer processing systems are provided including an extrusion assembly, a specially configured decompression chamber assembly, and a die assembly. Such systems are effective to provide shaped polymer products having reduced extrusion markings.

The invention discloses a cedarwood fiber-based bio-composite material and a preparation method thereof. According to the preparation method, the advantages of good toughness, corrosion resistance, moth resistance, low cost and the like of abandoned cedarwood fibers are fully utilized, the cedarwood fibers are processed through a high temperature extrusion process in an earlier stage, then the cedarwood fibers are mixed with polyvinyl chloride (PVC), and matched with other additives, and proper processing steps and parameters are adopted, so as to obtain the bio-composite material which is high in strength, high in toughness and low in cost by squeezing granulation through a screw rod. The material can be processed to form various products through ways of injection molding, extrusion, mould pressing, machining and the like, is widely used in the fields of packaging, electronics, communication, furniture, decoration, automobiles, airplanes, war industry and the like, is capable of replacing the materials of plastic, logs and the like, and has very good social benefit and economic benefit.
