In the manufacturing process of wood products, a large amount of fine wood powder is generated. There is a growing movement to reuse this wood powder by compounding it with plastic to create new wood products. Due to various constraints in wood powder compounding, a twin-screw extruder with a deep groove screw like the 'TEX' and advanced kneading technology are required. This document introduces wood powder compounding using our twin-screw extruder 'TEX'. We invite you to read it.

Recycled paper is mainly referred to as recycled paper in the context of old paper recycling, but there are other uses for old paper, such as cushioning materials and packaging made by blending old paper with plastics, as well as various containers. The blending of old paper and plastics is one of the technologies that should be established urgently from an environmental protection perspective. In the recycling of old paper using an extruder, the various forms of old paper and their low bulk density result in poor feedability into the extruder. Additionally, since paper is fibrous, it tends to tangle easily, making it a significant challenge to uniformly disperse it into the molten plastics. We have achieved the blending and pelletizing of old paper and plastics using our twin-screw extruder 'TEX'. 【Mixing Technology】 ■ Stability of raw material feed ■ Dispersion of old paper ■ Low-temperature extrusion ■ Devolatilization *For more details, please refer to the PDF materials or feel free to contact us.

We have developed a recycling technology for cross-linked plastics and cross-linked rubber, which previously had no treatment methods other than energy recovery through incineration or landfill, using "TEX." By equipping the system with a screen changer at the front, we can filter out debris that mixes with the crushed material. Additionally, the filter can be easily replaced during operation, allowing for continuous operation. This technology effectively performs cross-link cutting of cross-linked plastics such as wire insulation materials and cross-linked rubber (tires, weather strips, etc.). 【Features】 - Effectively performs cross-link cutting of cross-linked plastics such as wire insulation materials. - Effectively performs cross-link cutting of cross-linked rubber (tires, weather strips, etc.). - Enables continuous production of high-quality recycled products. - Allows for stable extrusion by precisely controlling the resin temperature, which is crucial for cross-link cutting. - All by-products can be collected through venting or slitting. *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to our continuous chemical recycling technology for plastics, utilizing our twin-screw extruder 'TEX' and associated equipment. The raw materials are continuously decomposed through shear heating by the extruder's screw and heat transfer from the cylinder heater. By condensing and recovering the decomposition gas into liquid monomers downstream of the extruder, we can efficiently remove decomposition gases and residues, resulting in high-quality monomers with harmful substances removed. 【Features】 ■ Efficient continuous production of high-quality recycled plastics ■ Capable of recycling various materials other than acrylic ■ Stable supply of raw materials in various shapes, such as film scraps and crushed pieces, to the extruder ■ Specification considerations using test equipment are also possible *For more details, please refer to the PDF document. Feel free to contact us with any inquiries.

Our company is working on the development of recycling technology for plastics and rubber with cross-linked structures, which are generally considered difficult to recycle, by utilizing the twin-screw extruder 'TEX'. 'TEX' effectively cuts the cross-linking by finely grinding supplied coarse crushed rubber with a kneading screw, followed by heating, compression, and shearing action. Since the conditions suitable for cross-link cutting, such as resin temperature, screw rotation speed, and shear stress, can be precisely controlled, it enables the continuous production of high-quality recycled products effectively and stably. 【Features】 ■ Filtration of impurities is possible by equipping a screen changer at the front end. ■ Continuous operation is possible as the filter can be replaced during operation. ■ Further efficiency can be achieved by using liquid additives for cross-link cutting. ■ By-products can be collected through venting or slitting, etc. *For more details, please refer to the materials.

The "TEX Twin-Screw Extruder" is a dechlorination treatment device that efficiently thermally decomposes chlorine-based polymers in waste plastics and allows for the efficient removal of hydrogen chloride through a twin-screw extrusion method. Thanks to external heating of the cylinder and the shearing action of the screw, it enables efficient and uniform melting, plasticizing, and thermal decomposition of waste plastics, which is difficult with conventional heating devices. Additionally, by removing hydrogen chloride gas, waste plastics can be utilized as a more efficient solid fuel or as resources for oilification or gasification. 【Features】 ■ High dechlorination performance ■ Stable dechlorination treatment ■ Prevention of adhesion within the device ■ Flexible adaptability to raw material formulations ■ Efficient melting, plasticizing, and thermal decomposition *For more details, please refer to the PDF materials or feel free to contact us.
