Problems solved by technology

[0003] At present, rubber tree logs are usually processed in the form of planks and square strips, chemically preserved and kiln-dried as sawn timber, and sold to wood products companies such as solid wood furniture. Small logs of tree roots and branches are generally crushed and used as particleboard raw materials, which are difficult to directly use as raw materials. The use of solid wood boards has low added value. After the trees are felled, they generally need to be processed, preserved and dried within 1-2 weeks, otherwise the wood is prone to blue stains, moths and decay
[0004] Nowadays, people gradually love the natural form of wood, such as using small-diameter logs as interior decoration walls, or using small-diameter logs such as rosewood and boxwood to make follow-up pen holders, or loving the roots of nanmu and camphor wood to make coffee tables and Drum stools, etc., but the resources of such precious tree species are gradually decreasing, and the fast-growing wood of ordinary plantations is rarely used as materials for carving and handicrafts due to its lack of color, texture, density and dimensional stability.

Abstract

The invention belongs to the technical field of wood processing, and relates to a processing and production method for rubber tree logs, in particular to a method for producing root carvings and wood piers from rubber tree logs and root materials. The rubber tree roots and logs are processed through a specific drying process, Not only the traditional drying defects are overcome, but also the rubber wood logs and root materials produced by the invention have the characteristics of stable wood size, not easy to deform, and are suitable for producing products such as root carvings, pen holders and wooden piers.

Description

technical field [0001] The invention relates to the field of rubber tree wood processing, in particular to a method for producing root carvings and wooden piers from rubber tree logs and root materials. Background technique [0002] Rubber trees (Hevea brasiliensis) are planted in large numbers in the tropics and Southeast Asia in my country. The annual output of rubber plantations in my country exceeds 2 million cubic meters. Rubber wood is a loose-porous wood, easy to process, and has a pleasing texture. It is currently widely used in furniture and interior decoration, and is an important commercial wood for tropical plantations in my country. Due to artificial cultivation, trees grow faster, logs contain 6%-10% starch and 1-2% soluble sugar, and wood is prone to decay, moth-eaten and mildew. At present, enterprises use boride and chemical antifungal agent pressure immersion treatment, and then conventional kiln drying process to produce commercial sawn timber, generally ...
