Example Embodiment

[0019] A method for industrialized harmless utilization of water hyacinth comprises the following steps:

[0020] Step 1: Collect fresh water hyacinth, clean the soil on the surface of water hyacinth, and cut into sections;

[0021] Step 2: Put the water hyacinth section into the electric heating blast dryer to dry, and take it out when the water hyacinth section is completely dried to an absolutely dry state;

[0022] Step 3: Put the water hyacinth segment in the dry state into the electric pulverizer for crushing, and then sieve through a 100-mesh sieve to make water hyacinth dry powder for use;

[0023] Step 4: prepare phenolic resin, the mass ratio of each raw material is: phenol (C 6 H 5 OH): formaldehyde (CH 2 O): NaOH=1:2.2:0.5;

[0024] Step 5: At a temperature of 40-45 °C, put the dissolved phenol and part of the formaldehyde (2 / 3 of the total) into the reactor, and add a catalyst (30% NaOH solution), and the input amount is 1 of the total. / 3, then keep the temp...

Abstract

The invention relates to an industrial harmless utilization method of a water hyacinth, which comprises the following steps: firstly cleaning, cutting up, drying, smashing and screening the water hyacinth to prepare water hyacinth dry powder; and then mixing the water hyacinth dry powder with a phenolic resin adhesive to prepare bamboo green plywood through processes: gluing, seasoning, assembling, hot-pressing and the like. The bamboo green plywood prepared through the process can meet the requirement on bonding strength prescribed in the national standard GB/T14074.10-1993 testing method for wood adhesive and resin, replaces the filler flour in the present plywood production, achieves the purposes of lowering the production cost of the plywood and eliminating the harm of the water hyacinth on ecological environments in different areas of China. Therefore, the method has a wide development prospect.

Description

technical field [0001] The invention relates to an industrialized harmless utilization method of water hyacinth. Background technique [0002] Water hyacinth( Eichhornia crassipes ) is a perennial floating herb, which is recognized as one of the most important biological invasive species by countries all over the world due to its strong adaptability and fast reproduction. In 1901, water hyacinth was introduced into China as an ornamental plant. In the 1950s and 1960s, it was widely used as feed for pigs in lakes and ponds in the south during the period of extreme food shortage in my country. Due to the strong reproductive ability of water hyacinth and the lack of natural enemies in my country as an invasive species, it has spread rapidly in the waters of southern my country. In recent years, the grass has spread to disasters in 17 provinces (cities and autonomous regions) in southern my country, bringing great ecological and social harm. [0003] The damage of water hyaci...
