Abstract
The invention relates to a bamboo bleaching method. Soaking bamboo material in sodium hydroxide solution, bleaching in hydrogen peroxide solution with small amount of acetic acid, washing and drying. Has the characteristics of simple method and low cost.
Description
The present invention relates to a kind of bleaching process for bamboo material.
Along with the raising of people's living standard, people are also more and more higher to the requirement attractive in appearance of bamboo product.So handling, the bleaching of bamboo wood just seems even more important.Present known bleaching process for bamboo material be with the bleaching liquid that bamboo wood places clorox or hydrogenperoxide steam generator to add fluorescent whitening agent decide float processing after, put into sodium metasilicate or dithionic acid sodium solution again and protect and float processing, clean at last, drying.Though these method for bleaching can reach the purpose of bleaching bamboo wood, also exist technology complexity, the higher shortcoming of cost, the bamboo wood hygienic requirements after the bleaching is also difficult satisfactory.
The object of the present invention is to provide that a kind of bleaching process is more simple, cost is low, the bleaching process for bamboo material of safety and sanitation.
Task of the present invention is achieved in that and adds an amount of acetic acid in hydrogen peroxide bleaching liquid.The bamboo wood of handling with this bleaching liquid does not need to float processing through protecting again, thereby has simplified technological process, has saved cost again.
Technological process of the present invention is as follows:
1, bamboo wood was flooded 30 minutes with 1.5% NaOH (NaOH) hot solution (50 ℃).
2, will place through the bamboo wood behind the sodium hydroxide solution dipping and contain 2% hydrogen peroxide (H
2O
2), 0.05% industrial acetic acid (HA
C) bleaching liquid in closed processes 24 hours.The initial temperature of bleaching liquid was about 75 ℃ when bamboo wood placed.
3, will bleach that bamboo wood cleans or with dry getting final product after the clear water drip washing in clear water.
Bleach bamboo wood with the present invention, it is simple to have method, easy and simple to handle, with low cost, advantages such as non-toxic sanitary, and the bamboo wood after bleaching has aromatic odor.
Claims (2)
1, a kind of bleaching process for bamboo material after the impregnation process, places the bleaching of hydrogen peroxide bleaching solution to handle in sodium hydroxide solution bamboo wood, and feature of the present invention is directly to add acetic acid in hydrogen peroxide bleaching solution.
2,, it is characterized in that the concentration of hydrogen peroxide and acetic acid is respectively 2% and 0.05% in the hydrogen peroxide bleaching solution according to the bleaching process for bamboo material of claim 1.
