WPC analysis process and product advantages

The release date:2016-08-31 14:57:48 Visits:699

That WPC WPC, refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual adhesive resin is mixed with more than 35% -70% wood flour, rice husk, straw and other waste plant fiber into a new wood materials, plastics processing and then by extrusion, molding, injection molding process to produce plates or profiles. Is booming at home and abroad in recent years, a new class of composite materials. Wood-plastic composite materials containing plastic, which has good elastic modulus. Further, since the fiber-containing and sufficiently mixed with the plastic, which has a hardwood with considerable compressive, flexural and other mechanical properties, and its durability is better than ordinary wood. High surface hardness, typically 2 - 5 times that of wood. WPC processing process: the polymer can add some artificial zeolite, aluminosilicate this molecular powders can capture the odor-absorbing material. By amount of crystalline powder empty, the adsorbent can capture odors of small organic molecules. Molecular adsorbent has been successfully used to capture the polyolefin pipe extrusion, injection and extrusion blow molded containers, isolated packaging materials, extrusion packaging and sealing materials. Molecular adsorbent powder can also be added as a desiccant to remove the plastic moisture. Different sizes and shapes of the extruded product increases the diversity of WPC profiles is not required when a continuous sheet-like structure or component has a complicated structure design, WPC profile can be formed by injection molding or compression molding. Processors sometimes have to face the WPC in the process how to complete filling of the problem in order to solve this problem, they need to reduce the amount of wood filler to increase the melt flow. Since the upper limit is 200 ° C operating temperature processing of wood-plastic composites, and some of the resin melting point exceeds 200 ° C, such as PET, it can not be used for wood-plastic composites. Moisture can degrade the performance of the composite material but also contribute to the breeding of microorganisms, so be sure to remove moisture prior to use wood filler. Before molding wood filler should be dried, generally require moisture content of the treated less than 1 to 2%. Now WPC processing machinery requirements with feeding equipment, drying equipment, extrusion equipment and molding equipment, and the necessary downstream equipment such as cooling water tank, traction equipment and cutting equipment. WPC six advantages: (1) water and moisture. The fundamental solution of wood products after wet and aquatic environments absorbing moisture perishable, swelling deformation problem, you can use the traditional wood products can not be applied to the environment. (2) pest control, termite, effective way to eliminate insects harassment and prolong life. (3) colorful, many colors to choose from. Both natural wood texture and wood grain, and can customize according to their individual needs color (4) plasticity, can be very simple personalized style, fully reflects the personality style. (5) high environmental protection, pollution-free, pollution-free, can be recycled. Product does not contain benzene substance, formaldehyde content of 0.2, lower than the EO-class standards for grading European environmental standards, significant savings can be recycled wood use, national policy for sustainable development for the benefit of society. (6) high fire resistance. Effective flame retardant, fire rating to B1 level, fire self-extinguishing, does not produce any toxic gases.
