Embodiment Construction

[0007] The present invention mainly achieves high-grade pencil material by improving the physical properties of pine.

[0008] 1. According to the physical properties of the sand pine, the resin in the sand pine must be removed first. It is steamed and pressure-treated through the cooking plate tank. After a period of time, the resin can be removed and then dried.

[0009] 2. Put the dried sand pine pencil board into the softening tank. When the water temperature reaches a certain temperature, it is necessary to add a certain amount of softener, dispersant, cross-linking agent, penetrant and other materials, and keep it for a certain period of time to improve the physical properties of sand pine.

[0010] 3. During the above time, it is necessary to maintain a certain pressure in the softening tank, so that the physical properties of the sand pine pencil board can be improved to the greatest extent and easy to be rolled. Only by mastering these, can the sand pine pencil boa...

Abstract

A softening technology of an Abies holophylla Maxim. pencil board. Through softening technology, liquid line and resin of the wood are broken to improve the physical properties of the wood, so as to reach easy sharpening.

Description

technical field [0001] The invention belongs to the field of new products in the new material technology. In particular, it relates to a softening technology of sand pine pencil board. Background technique [0002] So far in our country, the material used for making pencils is mainly basswood, and the materials used for making high-grade pencil boards have not been developed and utilized. However, internationally, high-grade wooden pencils are made of Sida wood from the United States and Jierdong arbor from Southeast Asia. These two kinds of wood have a straight, uniform texture, light weight, little shrinkage, and good curling performance. It is deeply loved by international high-end pencil users. [0003] Sand pine is now mainly distributed in the Mudanjiang River Basin in Northeast China, Changbai Mountains and the 500-1200m above sea level in eastern Liaoning. Because it contains more rosin, it cannot be used for pencil boards at present, and the economic benefit is r...
