Understanding wood equipment

May 25th 2015 at 4:42 AM

After the last few years, the WPC by encouraging national recycling economic policy, as well as the potential benefits of demand-driven enterprise dual power, especially WPC successfully entered the Beijing Olympic venues and facilities construction, nationwide "WPC hot" this V They played in the ascendant. According to incomplete statistics, as of the end of 2008, connecting R & D on WPC industry chain, production, marketing and ancillary enterprises more than 200, including equipment manufacturers (including mold) accounted for 1/4 about. With the gradual expansion of WPC market, the domestic production capacity of WPC also greatly improved, wood products sales reached an annual output of 15 million tons, ranking second in the world; the individual manufacturer's level of technology has leapt in the world, its innovative products often make foreign counterparts with admiration. It should be said that this is a hard-won, exciting situation. However, it should be noted that China's industrial development is not balanced wood, some of the links are still problematic. In the author's Opinion, WPC production equipment research and development lag is a bottleneck restricting the development of Chinese wood.wood plastic composite manufacturers in ireland

Wood-plastic extrusion equipment in some of the features WPC processing methods and major equipment on the surface, and plastic processing is similar, but with a marginal as a multi-faceted, emerging industry professional features, its equipment, technology and processes related to polymer chemistry, material rheology wood chemistry, physical chemistry, fine chemicals, precision machinery, hydraulic, vacuum technology, thermal conduction, fluid mechanics, sensor technology, electronic automation and computer programming and many other professions and disciplines, its production equipment has its own distinct characteristics. After several years of exploration temper proved WPC as a new material with the independent nature of its processing difficulty far beyond the ordinary plastic products, manufacturing equipment is also growing tendency specialization and specialization, and thus produce many New features and requirements, such as:vinyl or plastic ceiling panels pretoria

1. Selection Requirements: production of wood-plastic products, because there are a lot of biomass fiber added, increasing the equipment barrel and screw wear, and therefore the material for the production of WPC equipment used must be higher strength, process is more complex metal materials, such as tungsten alloy bimetal coating material to enhance the wear resistance, extend equipment life.

2. Restructuring: Because the wood material contains a lot of wood flour, resulting in melt fluidity, extrusion resistance is increased, increasing the screw torque, so the screw designed to use more compression and melt faster, push and strong Multi-stage dual-cone structure to meet at the same speed at lower temperatures and with good plasticizing and delivery capabilities.redwood fences design
