Preparation method of reed fiber particleboard

Abstract

A method for preparing reed fiber particleboard. The reed raw material is cut by a circular saw machine to make a stalk-shaped reed of a certain size, and then cut by a reed cutter. Part of the scrap is boiled and softened to obtain reed fiber, and the other part is crushed again. The reed fine shavings are processed, and the reed fibers and shavings are respectively applied with different resin adhesives, dried, air-selected, paved into a three-layer or multi-layer structure slab, and pre-pressed into a continuous flat-press heat press machine. Pressing produces an environmentally friendly reed fiber particleboard. The advantage of the present invention is that the impact of the waxy layer on the surface of the reed on the bonding performance is reduced to the greatest extent through the step-by-step paving treatment. The production cost of the reed fiber particle board made by this process is moderate, and the physical and chemical properties all meet the requirements of the relevant national standards. Free formaldehyde The release amount meets the requirements of the E1 level standard. The invention makes full use of wetland reed resources, expands the source of raw materials for artificial board production, and meets the requirements of the country for building a resource-saving and environment-friendly society.

Description

technical field [0001] The invention belongs to the technical field of non-wood plant wood-based board production, and specifically relates to a new production process for making fiber particle boards by using grasses—reeds. Background technique [0002] Phragmites reed is a perennial tall herbaceous plant of the Gramineae family. It is widely distributed all over the world. It is an important wetland species widely distributed in the world. It is a highly differentiated morphologically differentiated species of meadow and wetland vegetation. High ecological and socioeconomic value, my country's reed resources are rich, widely distributed and concentrated, and now there are 14 main reed producing areas nationwide (Shandong Province is one of them, and Dongying City, Shandong Province has 500,000 mu of natural reed grassland , the annual output of high-quality reed is more than one hundred million kilograms), and the area of ​​reed is 1.3×106hm 2 Above, the economic value and ...

AI Technical Summary

Problems solved by technology

[0003] The reed fiber is long, and its aspect ratio and wall thickness to diameter ratio are within the range of excellent fiber materials, but its epidermis has a waxy layer, which contains non-polar silicon-containing substances and fatty substances. The urea-formaldehyde resin glue has poor wettability to the wax layer, and poor bonding performance to the reed wood-based panel
