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 rubber tree log material processing and producing method, in particular to a method for processing a root carving and a timber pier by using a rubber tree log and a root material. The rubber tree root and log are treated through special drying process, the traditional drying defects are overcome, and the rubber wood log and the root material produced by the method have the characteristics of stable wood size, difficulty in deformation and suitability for producing products such as root sculptures, pen containers and wood piers.

Description

technical field [0001] The invention relates to the field of rubber tree wood processing, in particular to a root carving and wooden pier processing method for rubber tree logs and tree roots. Background technique [0002] Rubber trees (Hevea brasiliensis) are planted in large quantities in tropical my country and Southeast Asia. The rubber wood logs produced by rubber plantations in my country exceed 2 million cubic meters every year. Rubber wood is a diffuse-porous wood, easy to process, and has a pleasing texture. It is currently widely used in furniture and interior decoration, and is an important plantation wood in tropical my country. Due to artificial cultivation, trees grow faster, logs contain 6%-10% starch and 1-2% soluble sugar, and the wood is prone to decay, insects and mildew. At present, enterprises use boride and chemical antifungal agent for pressure impregnation treatment, and then conventional kiln drying process to produce commercial sawn timber, general...
