RIDO chain guide usage

The chain guide, also called chain guide, is a hydrostatic guide that supports and guides the chain, reduces chain friction, reduces noise, and enhances the service life of the chain. High wear-resistance, temperature resistance, precision, stability, silence, environmental protection and other high-precision chain guidance. Chain guides and chain guides are involved in product material packaging, canning and conveying machines, food packaging machines, metallurgical equipment, printing machines, book binding machines, die-cutting machines, plastic nail linkage lines, saddle stitches, and printing machine manufacturing trusted partners. . High wear-resistant chain guides, wear plates, wear-resistant engineering plastics factory direct.

Product Performance The high molecular weight of UHMWPE, the chain guide of Dongguan City Dynamic Machinery Components Co., Ltd., gives excellent performance, and it is a thermoplastic engineering plastic with moderate price and excellent performance. It almost concentrates the advantages of various plastics and has ordinary Polyethylene and other engineering plastics have unparalleled comprehensive properties such as wear resistance, impact resistance, self-lubrication, corrosion resistance, impact energy absorption, low temperature resistance, adhesion resistance, water absorption, and low density. In fact, there is no single polymer material with so many excellent properties.

Wear resistance of chain guide rail UHMWPE The wear resistance of chain guide UHMWPE of Dongguan City Dynamic Machinery Components Co., Ltd. ranks the highest among plastics and exceeds the wear resistance of some metals, UHMWPE and other materials. Compared with other engineering plastics, the mortar wear index of chain guide UHMW-PE is only 1/5 of PA66, 1/10 of that of HEPE and PVC, 1/7 of that of carbon steel, and 1 of brass. /27. This high abrasion resistance makes it difficult to test the degree of wear resistance by using a general plastic abrasion test method, and thus a mortar abrasion test device has been specifically designed. The wear resistance of the UHMWPE chain guide UHMWPE is directly proportional to the molecular weight. The higher the molecular weight, the better the wear resistance.

Processing technology Because the viscosity of the ultra-high molecular weight polyethylene (chain guide UHMW-PE) in the molten state is as high as 108 Pa*s, the fluidity is extremely poor, and its melt index is almost zero, so it is difficult to process it by ordinary machining methods. In recent years, the processing technology of ultrahigh molecular weight polyethylene (chain guide UHMW-PE) has been rapidly developed, and the UHMW-PE has been suppressed from the initial stage by the transformation of ordinary processing equipment. - Sinter forming has evolved into extrusion, blow molding and injection molding as well as other special methods of forming.

General Processing Technology Pressed sintering Pressed sintering is the most primitive processing method for UHMW-PE (Ultra High Molecular Weight Polyethylene). This method has low production efficiency and is prone to oxidation and degradation. In order to increase production efficiency, direct electric heating method [1] can be used. In addition, Dongguan Dynamic Machinery Parts Co., Ltd. has developed an ultra-high-speed sintering processing method [2] using a blade-type mixer with the largest blade rotation. The speed can reach 150m/s, so that the material can be raised to processing temperature in only a few seconds.

Extrusion molding Extrusion molding equipment mainly includes plunger extruder, single screw extruder and twin screw extruder. Twin-screw extrusion uses co-rotating twin-screw extruders. Most of the 60s used plunger extruders. In the mid-1970s, Japan, the United States, and West Germany developed the single screw extrusion process. Japan Mitsui Petrochemical Company first achieved the success of round bar extrusion technology in 1974. At the end of 1994, China developed a special single-screw extruder of Φ45 type UHMW-PE (chain guide UHMW-PE), and in 1997 achieved the success of the Φ65-type single screw extrusion pipe industrial production line.

Injection Molding Japan Mitsui Petrochemical Corporation developed an injection molding process in 1974 and commercialized it in 1976, and later developed a reciprocating screw injection molding technology. In 1985, Hoechst of the United States also achieved the ultra-high molecular weight polyethylene (UHMW-PE) screw injection molding process. In 1983, China's domestic XS-ZY-125A injection machine was modified to successfully inject the ultra-high molecular weight polyethylene (chain guide UHMW-PE) support wheel and water pump bushing for beer canning production lines. Successfully injected medical artificial joints.

When the blow molding UHMW-PE is processed, when the material is extruded from the die, a certain shrinkage occurs due to the elastic recovery, and almost no sagging occurs. Therefore, it is a hollow container. In particular, large containers such as fuel tanks and vats create favorable conditions for blow molding. Ultrahigh molecular weight polyethylene (chain guide UHMW-PE) blow molding can also result in vertical and horizontal strength and performance of high-performance thin film, thus solving the long-standing vertical and horizontal strength of HDPE film inconsistency, easy to cause vertical damage.
