high hardness outdoor decking for sale
article molding equipment and molding process - how molding machinery, mold design and set up given the right conditions (molding temperature and pressure), in order to maintain stable feeding, devolatilization effectively, improve wood flour in the blended dispersion system to ensure product performance as the main purpose.wood plastics composites for decking in usa
the following will be specifically addressed these issues. improve polymer materials and plant fiber compatibility way non-polar or weakly polar polymer materials and plant fibers polar poor compatibility, thus without any pretreatment or add WPC additive performance is poor. thus to improve the performance of WPC,outdoor decking floor in austria
the two components must be modified accordingly, in order to make the two compatible polymer matrix for WPC, there are three main ways to improve the compatibility: part of wood processing wood processing divided into two major categories of chemical and physical methods: chemical methods: surface grafting method: modified graft is an effective method, before the complex or composite plant fiber simultaneously graft. engineered utility hardwood floors install
As can with maleic anhydride, isocyanate and other grafted plant fibers. interfacial coupling method: form a covalent bond with the coupling agent with the plant fibers to change interfacial adhesion. Such as silane coupling agents, titanate coupling agent, an aluminum coupling agent, etc. treated fiber, fiber and resin to improve compatibility.plastic wall cladding Switzerland
