Softener and application method thereof in slicing bamboo wood

Abstract

The invention discloses a softener and an application method thereof in slicing bamboo wood. The softener is composed of the following components by weight percentage: 20-30% of sodium carbonate, 20-40% of glycerol, 35-45% of alcohol and 4-6% of sodium fluoride. The application method comprises the following steps: adding the softener at the ratio of 8-12% into pool water to be prepared into softening liquid; putting a bamboo board blank to be softened into the pool; after dipping for 24-48 hours at normal temperature, increasing the temperature to 55 DEG C by boosting two DEG C per hour; keeping for 60-72 hours, and stopping boosting the temperature; and when temperature is lowered to 28-30 DEG C, taking out the bamboo board blank; and entering the next working procedure. The invention has the beneficial effect that the softener has minimum damage on bamboo wood and adhesive layers, has no harm and toxicity and has obvious softening effect, short softening period, small energy consumption, easy operation and low cost; slicing yield is above 90%, and slicing thickness can reach 10-12 decimillimetres.

Description

1. Technical field [0001] The invention relates to a bamboo plywood processing technology, in particular to a softener and its application method on sliced ​​bamboo. 2. Background technology [0002] my country's forest resources are in short supply, and the cycle of tree formation is long. Protecting forest resources is the common responsibility of all. Relatively speaking, my country is rich in bamboo forest resources, bamboo grows fast, and the forestation period is 2-3 years. Reasonable harvesting and utilization of bamboo is conducive to the growth of bamboo forests; it is an inevitable trend for bamboo plywood to replace wood plywood with its higher cost performance. In the existing process of making bamboo plywood, the softening agent of bamboo is mostly strong acid or strong alkali, such as the bamboo softening agent involved in Chinese patent CN1621580A "a kind of preparation method of bamboo fiber" contains alkali, sodium silicate, sodium tripolyphosphate, Sodium ...

AI Technical Summary

Problems solved by technology

In the existing process of making bamboo plywood, the softening agent of bamboo is mostly strong acid or strong alkali, such as the bamboo softening agent involved in Chinese patent CN1621580A "a kind of preparation method of bamboo fiber" contains alkali, sodium silicate, sodium tripolyphosphate, Sodium sulfide, etc., have problems such as long softening time, large energy consumption, great damage to the rubber layer of bamboo and bamboo fibrous structure, poor softening effect, and low rate of planing. At the same time, it is easy to damage the health of workers and pollute environment, damage to ecological security
